Abstract

The present invention relates to Fabrid care composition, it contains a kind of silicone gel, thereby makes fabric be easy to ironing, and the outward appearance after the ironing is improved.

Description

The present invention relates to fabric care compositions and a method of treating fabrics to improve various properties of fabrics, especially ease of ironing and improved appearance after ironing.

Most of the clothes in the world today are made from textiles, which have been known for centuries. The invention of textiles in general is indeed to be attributed to ancient Egypt. The natural cotton, wool or flax fibers are made into yarn, and the textiles made from these yarns are used to make clothes. The clothes are often damaged in the process of wearing, and it takes a lot of time and effort to iron them when washing to keep them in good condition. The original look.

During the past half century, textile manufacturers have made two major improvements in the washing and wearing of clothes: (1) the use of cross-linked resins in cotton-containing clothes, and (2) the use of synthetics and synthetic mixtures. Although these two measures have made great progress in reducing the wrinkling of clothes, consumers are still not satisfied with the results and still think that ironing is necessary.

The term "ease of ironing with improved appearance after ironing" as used herein means that the fabric only needs to be ironed a little, (it can increase the ironing slip and make it easier to remove wrinkles), and after a specific cleaning operation, it is then After re-ironing there are fewer wrinkles than after normal washing operations and ironing.

It is therefore an object of the present invention to provide compositions which make the treated garments particularly easy to iron/better in appearance after ironing. This and other objects are accomplished by the present invention, as will be seen from the following description.

The present invention relates to fabric care compositions comprising a silicone gel agent which, when used in fabric cleaning operations, deposits an effective amount of the silicone gel on the fabric to render it easy to iron, and The appearance is improved after ironing.

The silicone gel composition involved in the invention can make the fabric easy to iron and improve the appearance after ironing. In another aspect, the present invention relates to a method of fabric care using such a silicone gel composition for ease of ironing and improved appearance after ironing. Preferred compositions are aqueous liquids which also contain a fabric softener and/or a surfactant or a starch. The compositions are usually added to the detergent or rinse water used in laundry operations, preferably these compositions are water-based, water-dispersible additives containing from about 0.1% to 80%, preferably from about 0.1% to 50% silicone gel, dilute these additives in detergent or rinse water.

Surprisingly, the combination of silicone gel with a suitable carrier that deposits an effective amount of silicone gel on the fabric results in fabrics that are easy to iron and have an improved appearance after ironing . Accordingly, several silicone gel-containing fabric care compositions are disclosed herein. Several methods of treating fabrics with silicone gels for ease of ironing and improved appearance after ironing are also disclosed.

The silicone gel compositions of the present invention are used with a suitable carrier. The term "carrier" as used herein means any suitable carrier (liquid, solid or mechanical) for delivering and depositing the silicone gel on the fabric, such as the ability to add the silicone gel to a water-based In softener or detergent compositions, or in an aqueous emulsion. It is available in bottled liquid sprays. Preferred embodiments include the liquid rinse water component comprising silicone gel plus fabric softener.

In a preferred embodiment, from about 0.1% to about 10% by weight of the silicone gel is mixed with a suitable commercially available laundering liquid fabric softener composition. The result is a fabric care composition which provides ease of ironing and better ironed appearance of treated fabrics.

，或非离子型表面活性剂基洗涤剂，如BOLD₃液体 ）中，注意必须使用与洗涤剂表面活性剂相容的硅氧烷凝胶乳浊液，以免该硅氧烷凝胶脱乳化。这种新型的液态洗涤剂/硅氧烷凝胶产物具有意想不到的易于熨平且熨平后外观得以改善的效果。在另一种方案中，将硅氧烷凝胶直接喷在浸湿的织物上。在洗涤剂或冲洗液中，硅氧烷凝胶的含量约为1-300ppm，最好为5-150ppm。在直接喷射时，硅氧烷凝胶含量应更高，如1000ppm至200000ppm。In another version, an equal amount of silicone gel is mixed into a suitable commercially available liquid detergent and/or softener composition (anionic/nonionic surfactant based detergent, as liquid TIDE

, or a non-ionic surfactant based detergent such as BOLD ₃ Liquid ), note that a silicone gel emulsion compatible with detergent surfactants must be used to avoid demulsification of the silicone gel. This novel liquid detergent/silicone gel product has the unexpected effect of easy ironing and improved appearance after ironing. In another approach, the silicone gel is sprayed directly onto the wetted fabric. In detergent or rinse solutions, the silicone gel is present in an amount of about 1-300 ppm, preferably 5-150 ppm. When spraying directly, the silicone gel content should be higher, such as 1000ppm to 200000ppm.

In another aspect, the invention includes a liquid starch composition comprising the silicone gel plus starch and a suitable carrier. In a preferred embodiment, from about 0.1% to about 10% by weight of the emulsified silicone gel is mixed into a suitable commercially available pumpable starch composition. The result is a sprayed starch composition which makes the sprayed fabric easier to iron and has an improved ironed appearance. Suitable commercially available sprayable starch compositions consist essentially of water and a suitable emulsifier. Note that a silicone gel emulsifier compatible with the starch and silicone gel must be selected to avoid demulsification. A second approach involves laundry rinses wherein the silicone gel is present in the rinse water at about 1-300 ppm, preferably at about 5-150 ppm.

Without wishing to be bound by theory, it is believed that once these silicone gels are deposited on the fabric, during the washing process it spreads and forms a three dimensional film on the fabric which will facilitate easy ironing, during the ironing process Eliminates wrinkles and makes the fabric look better after ironing.

Best care is taken to ensure that the compositions of the present invention are substantially free of heavy waxes, abrasives, fiberglass and other fabric discomforts.

silicone gel

Silicone gel is a cross-linked product of silicone fluid and silicone resin. Silicone fluids are defined as flowable silicone polymers of variable viscosity, which may be branched or linear. In general, silicone resins are highly crosslinked siloxane solid systems with crosslinks introduced as trifunctional (T) (e.g. RSiO _1.5 ) or tetrafunctional (Q) (e.g. SiO ₂ ) units. components. The resin becomes more brittle due to the addition of only tri- or tetrafunctional units without the addition of monofunctional or terminal components (M) (eg, R ₃ SiO _0.5 ).

The most important thing of the present invention is that due to the addition of the difunctional unit (D) (eg, R ₂ SiO), the resin becomes soft and can be regarded as a silicone gel. In addition to the effects of mono-, tri-, tetra-, and difunctional units on silicone resins and gels, changing organic groups can also affect their properties. The terms Q, tetra- and quat- are synonyms. Usually silicone resins and gels use methyl, phenyl, vinyl and mixtures thereof as organic groups, but not too limited. Other possible groups include amines (mono-, di-, tri-, quaternary, cyclic, di-, and tri-amines), epoxides, esters, ethers, halogen-functional organics, carboxyl groups, etc., including hydrogen.

The importance of the silicone gel to the present invention is that it is softer than the resin and less cross-linked (i.e., tri-(T) and/or tetra-(Q) low content of functional units). The silicone gels of the present invention have a higher degree of crosslinking than silicone fluids or viscous silicone gums. More specifically, preferred silicone gels have about 3%-30% T and/or Q functional units, about 70%-97% D functional units, and about 0.1%-10% M functional units; Alkane gel has about 5%-20% T and/or Q functional unit, about 80%-95% D functional unit, about 0.3%-8% M functional unit is better, preferably this silicone gel has about 5%-15% T and/or Q functional units, about 85%-95% D functional units, about 0.5%-5% M functional units, where M is curable and can be represented by the following molecular formula

wherein R and R' are preferably mutually independent alkyl groups or H or some other groups (but not limited to) selected from the following groups: amines (mono-, di-, ternary, quaternary, cyclic, di- and triamines), epoxides, esters, ethers, halogen-functional organics, carboxyl groups, etc., including hydrogen. The molecular weight of the polymeric silicone gel should be greater than about 20,000; greater than about 50,000; even greater than about 100,000; Theoretically, their molecular weight can be as high as 10 ²⁰ . Preferred polymeric siloxanes of the invention are below 10 ¹⁵ , even more preferably below 10 ¹⁰ . An important factor is that the polymeric silicone is in gel form. When the content of T and/or Q functional units is high, the molecular weight of the gel is lower.

In addition, the silicone gel must be in such a form that it is preferably applied to the laundered fabric through an aqueous carrier; thus emulsified forms are ideal, however not limited to emulsions of preformed gels, silicone The alkane gel itself to form an emulsion is the best way to practice the preferred embodiment of the invention.

This can be accomplished in a number of different ways. There are usually two methods: (1) emulsion polymerization (see US4600436, Traver/Thmineur/zotto, issued July 15, 1986, for Durable Silicone Emulsion Polish, which has been included in the references of this article, especially column 6.11, 35-47 ); (2) Emulsification of polymers followed by curing in emulsion (see "Siloxanes", Hardman et al., Encyclopedia of Polymer Science and Engineering, Vol.15, Second Edition, Pages 204-308, John Wiley and Sons, Inc., 1989, also incorporated herein by reference). Harding et al. identified four curing methods: (1) concentration; (2) peroxide; (3) platinum-catalyzed hydrosilylation; and (4) ultraviolet light. These curing methods are known in the art, but care must be taken in the choice of starting materials and reaction conditions to ensure the desired "gel".

One particular method of preparing the gel is to emulsify the curable branched silicone polymer and then cure the polymer into the gel in the emulsified droplets prior to application to the fabric. For example: a kind of emulsified branch curable amine function siloxane (test emulsion, provided by General Electric Company, No.124-7701, which is 9-10 in the glass container, it is available on the market The 20% emulsion of curable amine functional silicone GE, sold under the trade name SF1706) can be heated at 50°C for 5-10 days to form an emulsified silicone gel.

This silicone gel is made from a branched curable amine functional silicone with the following structure:

Wherein X is equal to Z+2; Y is at least 3; Z is at least 1; R', R" are C _1-20 alkyl or selected from cyclic amines, polymeric amines and alkyl chains containing about 2-7 carbon atoms Amino groups of alkylamines where at least R' or R" is an amine group; curable amine-functional silicones are cured in emulsified form by heating and/or addition of a base to produce an emulsified silicone Oxygen Gel.

Preferred siloxanes are when: R is hydrogen or a C _1-3 alkyl; ^R is a C _1-3 alkyl; R" is an alkylamine containing about 2-7 carbon atoms in the alkyl chain Group; wherein the curable amine-functional silicone is cured in emulsified form by heating and/or adding a base to produce an emulsified silicone gel.

More preferred siloxanes are when: R is methyl; R' is methyl; R" is (CH ₂ ) ₃ NH(CH ₂ ) ₂ NH ₂ ; X is about 4; Y is about 27 and Z is about 2; wherein the siloxane has a molecular weight of about 1000-2800 and a viscosity of about 5-40 centistokes at 25°C; the curable amine-functional siloxane is cured in emulsified form by heating and/or adding a base to produce a Emulsified silicone gel.

The physical properties of this system differ considerably from the starting polymer. Use of curable amine functional siloxane is beneficial for wrinkle reduction, which has been disclosed in previous U.S. patents, such as US4800026, coffindaffer/wong, approved on January 24, 1989; US4911852, coffindaffer/Trinh approved on March 27, 1990; .8 granted, all of which are incorporated herein by reference, in which a polymer is added to a fabric and then cured by reacting with other silicones, much to our surprise, if the The polymer solidifies to form a gel in an emulsion, which is then delivered through a liquid carrier, resulting in ease of ironing and an improved appearance after ironing, which is evident to consumers.

Increasing the pH of the emulsion shortens the reaction time to prepare the gels disclosed above. For example, at a pH of 13, an emulsified SF1706 gel can be formed in 6-30 hours, depending on the degree of solidification desired prior to addition to the product. Raising the temperature from room temperature to about 75°C ± 15°C can also increase the curing reaction rate, while lowering the pH value will slow down the curing reaction rate, for example, when the pH is about 2.5, almost no curing occurs after one month at 23°C . Care should be taken to keep the temperature low enough to not denature the emulsion.

In this reaction, the amine and base in the system act as catalysts for the concentration and solidification reaction, and the effectiveness of alkali metal hydroxides as catalysts increases in the order of Li ⁺ <Na ⁺ <K ⁺ <Rb ⁺ <Cs ⁺ . There are many methods known in the prior art that do not require the use of amines or bases to cure silicone polymers, some of which are disclosed in Encyclopedia of Polymer Science and Engineering, Vol.15, Second Edition, Pages 204- 308, John Wiley and Sons, Inc., 1989, which are incorporated by reference herein.

One way to characterize silicone gels ^is29Si ; NMR. Even in emulsified form (with relaxation aids such as Cr(acac) ₃ ), MDT and Q are easily identified within the specified ranges above.

The fabric care compositions of the present invention comprise a suitable silicone gel and preferably another fabric care material selected from the group consisting of organic solvents, water, surfactants, fabric softeners, soil removers, Builders, brighteners, fragrances, dyes and mixtures thereof.

One embodiment of the present invention is a liquid fabric softening composition, which contains an effective amount of silicone gel and a softening agent selected from (such as US4661269, Trinh et al., approved on April 28, 1987, listed fabric softeners described in the references herein). US 3,904,533 (Neiditch et al., 1975, Approved 9.9, incorporated herein by reference) describes many other fabric conditioning formulations suitable for use in the present invention.

liquid detergent

Another embodiment of the present invention is a liquid detergent composition comprising an effective amount of silicone gel and a surfactant, such as selected from US4318818 (Letton et al., approved on March 9, 1982) ) and one described in US 4,911,852 (coffindaffer/Trinh, approved March 27, 1990) (both incorporated herein by reference). Suitable surfactants may be selected from anionic, nonionic, amphoteric, zwitterionic and cationic surfactants and mixtures thereof. In a preferred embodiment, about 0.1%-33%, more preferably about 0.5%-20%, and most preferably about 1.0%-10% of silicone gel are added to the total liquid detergent composition, resulting in a A product which, when the fabric is left to be laundered in the ordinary manner, provides a marked ease of ironing and an improved appearance after ironing.

some preferred implementations

A preferred composition of the present invention is an aqueous dispersion comprising: a silicone gel in a weight ratio of the silicone gel to the fabric softener of about 17:1 to 1:350, preferably About 10:1-1:100. Some more preferred weight ratios of silicone gel to fabric softener are 1:1 to 1:10 and 1:5 to 1:10. Adding these compositions to the rinse water can make the fabric easy to iron and improve the appearance after ironing, and it is also beneficial to the softness of the fabric.

Suitable fabric softeners are selected from the group consisting of:

ⅰ. Quaternary ammonium compounds;

ii. Aliphatic amine fabric softening compounds;

ⅲ. Aliphatic amide compounds;

ⅳ. Fatty acids;

v. Aliphatic alcohols; and

ⅵ. Its mixture

In the compositions of the present invention to which certain rinse solutions are added, the fabric softening agent is present in an amount of from about 2% to about 35%, preferably from about 4% to about 27%, based on the total composition. The lower limit of the amount must be such that it is effective to soften fabrics when added to a domestic laundry rinse tank in the conventional manner. The upper limit applies to more concentrated liquid products which need only be used in small amounts.

Preferred levels of silicone gel in the compositions, by weight of the concentrate, are from about 0.05% to 40%; from about 0.1% to 20%; from about 0.5% to 10%.

Suitable fabric softening compounds include quaternary and non-quaternary ammonium and amine salts.

Use of compositions containing cationic nitrogen-containing compounds (in the form of quaternary ammonium salts and substituted imidazolinium salts with two long-chain acyclic aliphatic hydrocarbon groups) to facilitate fabric softening during laundry rinsing (see, for example, US3644203, Lamberti et al. People, 1972.2.22 approval; US 4426299, Verbruggen, 1984.1.17 approval; also "Cationic surface Active Agents as Fabric softeners" R.R.Egan, Journal of the American Oil chemists' society, January and 1978, P1 to choose cationics for Fabric softeners," J.A. Ackerman, Journal of the American oil chemists' society, June 1983, P 1166-1169).

Other suitable fabric softening compounds are non-quaternary amides and non-quaternary ammoniums. The commonly cited substances are the reaction products of higher fatty acids and hydroxyalkylenediamines. An example of these substances are the reaction products of higher fatty acids with hydroxyethylethylenediamine (see "Concentrated products of β-hydroxyethylethylenediamine and fatty acids or their alkyl esters, and their use as fabric softeners in detergents Applications", H.W. Eckert, Fette-seifen-Anstrichmittel, September 1972, P 527-533). These materials are often used together with other cationic quaternary ammonium and imidazolinium salts as softening actives in fabric softening compositions. (seeing US 4460485, Rapisarda et al., 1984, approved July 17; US4421792, Rudy et al., 1983, approved December 20; US4327133, Rudy et al., approved 1982.4.27).

Particularly preferred fabric softeners are in the form of aqueous dispersions containing from about 3% to about 35% by weight of the following mixture:

(a) Reaction products of about 10% to 92% higher fatty acids with a polyamine selected from the group consisting of hydroxyalkylenediamines and dialkylenetriamines and mixtures thereof

(b) About 8%-90% cationic nitrogen-containing salts with only one long-chain acyclic aliphatic C ₁₅ -C ₂₂ hydrocarbon group and optionally containing

(c) 0% to about 80% have two or more long-chain acyclic aliphatic C ₁₅ -C ₂₂ hydrocarbon groups or one such group and an arane containing about 15-22 carbon atoms in the alkyl chain The cationic nitrogen-containing salt of the base.

A detailed description of certain preferred fabric softening agents can be found in commonly assigned US Patent 4,661,269 (Trinh/Wahl/Swartley/Hemingway, Approved April 28, 1987), incorporated herein by reference in its entirety.

Unless otherwise stated, terms herein, eg, softening compound, refer to both single and composite components.

starch

A preferred embodiment of the present invention is a liquid starch composition comprising an effective amount of silicone gel and up to about 99% of a liquid starch composition selected from conventional aqueous starch compositions. The composition comprises from about 0.1% to about 35%, preferably from about 0.5% to about 20%, of starch, a minor amount of surfactant, minor components and the balance being water. The use of starch aids in ironing and shaping and serves as a carrier for the silicone gel component. Accordingly, any water-based starch composition used in the fabric care art can be used in the present invention. For example, US4780499, Villarreal et al., approved October 25, 1988; US3644241, Falivene, approved February 1972; US3833393, Kandathil, approved September 1974; US4495226, Smith, approved January 22, 1985; (both incorporated herein by reference in its entirety), these patents disclose suitable starch and starch-derived compositions.

Preferred carriers are liquids selected from water and mixtures of water and short chain C ₁ -C ₄ monohydric alcohols. The water used can be distilled water, deionized water or tap water. Mixtures of water and up to about 10%, preferably less than about 5%, of a short chain alcohol such as ethanol, propanol, isopropanol or butanol and mixtures thereof can also be used as the liquid carrier.

Certain short chain alcohols are present in commercially available quaternary ammonium compound products. These products can be used to prepare the preferred aqueous compositions of the present invention and the short chain alcohols in these products generally comprise from about 1% to about 10% by weight of the aqueous composition.

Other carriers may be suitable solids, polyol waxes and waxy substances which are commonly used in detergents and drier softeners and spray containers.

Certain optional components and preferred embodiments

It is well known that compatible adjuvants can also be added to the compositions of the present invention, such adjuvants include, but are not limited to, viscosity modifiers, fragrances, emulsifiers, preservatives, antioxidants, bactericides, fungicides, Agents, coloring agents, dyes, fluorescent dyes, brighteners, opalescent agents, freeze-thaw regulators and shrinkage regulators and other agents that can be easily ironed (such as starch, etc.). If such adjuvants are used, they are generally added in amounts of up to about 5% by weight of the preferably liquid composition at a time.

Viscosity modifiers can be organic or inorganic. Examples of organic viscosity modifiers are fatty acids and esters, fatty alcohols, and water-miscible solvents such as short chain alcohols. Examples of inorganic viscosity modifiers are water-soluble ionizable salts. A wide variety of ionizable salts can be used. Examples of suitable salts are the halides of Group _IA and _IIA metals of the Periodic Table, such as calcium chloride, magnesium chloride, sodium chloride, potassium bromide and lithium chloride. Calcium chloride is preferred. The ionizable salts are particularly useful when mixing the components to form the liquid compositions of the invention and bringing the compositions to the desired viscosity. The amount of ionizable salt depends on the amount of active ingredient in the composition and can be adjusted according to the formulation requirements. The salt concentration used to control the viscosity of the composition is generally 20-6000 parts per million (ppm) by weight of the composition, preferably about 20-4000 ppm.

Compatible bactericides are generally used in the compositions of the present invention at concentrations of from about 1 ppm to about 1500 ppm by weight of the composition.

This mixture, containing approximately 5% silicone gel, was used as a pre-ironing spray to allow easy ironing of the fabric and improved appearance after ironing.

Examples VI and VII

Two other starch/silicone gel compositions were prepared as in Example V. About 5 parts and 50 parts of the 20% silicone gel emulsion were mixed with the liquid SPRAY'N STARCH composition to obtain stabilized 1% and 10% silicone gel compositions, respectively.

The starch composition is stable.
