Definitions
- the present application relates to a process for the hydrophilic finishing of fibers which exclusively or predominantly contain polyolefins or polyesters or of nonwovens which contain polyolefin or polyester fibers and also fibers or nonwovens which are made hydrophilic by this process.
- absorbent materials are used to absorb aqueous liquids.
- this material is covered with a thin, water-permeable nonwoven.
- nonwovens are usually made from synthetic fibers, such as polyolefin or polyester fibers, since these fibers are inexpensive to produce, have good mechanical properties and, in the case of polyolefin, can be thermally bonded.
- untreated polyolefin or polyester fibers are not suitable for this purpose, since their hydrophobic surface means that they do not have sufficient permeability to aqueous liquids.
- the fiber surface must be made hydrophilic by an appropriate preparation.
- the hydrophilic finish of the fiber is preserved as long as possible without the water permeability of the nonwoven being reduced. If such nonwovens are processed, for example, in diapers, they can be used several times without becoming leaky. In this way, the wearing time of the diapers is increased and the waste caused by used diapers is reduced.
- No. 5,045,387 describes, for example, an agent for the hydrophilic finishing of polyolefin fibers, which contains a mixture of an alkoxylated ricinoleic acid derivative, a hydrogenated ricinoleic acid derivative, a Ci "fatty acid and a polyalkoxylated polymethylsiloxane.
- EP 372 890 B1 discloses fibers which are polyolefins or Comprise polyesters and have been treated with an agent containing a fatty acid diethanolamide, a polyether-modified silicone, a sorbitan fatty acid ester and a metal salt of an alkyl sulfonate. The disadvantage of such preparations can be seen above all in their high price.
- the object of the present invention was to provide an improved process with which polyolefin or polyester-containing fibers or nonwovens which contain polyolefin or polyester fibers can be given a hydrophilic finish, the hydrophilic finish being to be retained even after repeated wetting.
- the invention therefore relates to a process for the hydrophilic finishing of fibers which contain exclusively or predominantly polyolefins or polyesters or of nonwovens which predominantly contain such fibers, the nonwovens being mixed with an aqueous dispersion of a preparation which comprises 50 to 95% by weight, based on the Total weight of the preparation, at least one quaternary esteramine salt of the formula (1),
- R 1 is an aliphatic alkyl radical having 12 to 22 carbon atoms
- R 2 is either a radical (CH 2 ) n -O-COR ', or an alkyl radical having 12 to 22 carbon atoms
- R 3 and R 4 are independently a radical (CH 2 ) n -R 5 , where R 5 is H or OH and n is a number between 1 and 3 and X is either a halide, methosulfate, methophosphate or phosphate ion, 5 to 50 wt .-% of at least one alkyl glycoside with the general formula RO (G) x in which R represents a primary straight-chain or methyl-branched aliphatic radical having 8 to 22 C atoms and G represents a glycoside unit having 5 or 6 C atoms and x represents a number between 1 and 10, and contains 0 to 30% by weight of glycerin.
- RO (G) x in which R represents a primary straight-chain or
- the process according to the invention is suitable for fibers which contain exclusively or predominantly, ie more than 50% by weight, polyolefins or polyesters and for nonwovens which predominantly contain such fibers, fibers which exclusively contain polyolefins or polyesters being preferred.
- Nonwovens containing 100% by weight of polyolefin or polyester fibers are particularly suitable.
- Polyolefin fibers are among the most commonly used fibers in the manufacture of nonwovens. Examples of suitable polyolefins are polypropylene, polyethylene or copolymers of ethylene or propylene with butadiene. Polyester fibers, mainly polyethylene terephthalate fibers, are also used.
- nonwovens can also be used, for example fibers made of Nylon® . Fibers consisting of two or more components are also particularly suitable, for example polyester-copolyester fibers or polypropylene-polyethylene fibers.
- the nonwovens used in the process according to the invention can be produced by all processes of nonwoven production known in the prior art, as described, for example, in Ullmann's Encyclopedia of Industrial Chemistry, Vol. A 17, VCH Weinheim 1994, pages 572-581. Nonwovens which are produced either by the so-called “dry laid” method or by spunbonding or spunbonding are preferred.
- the “dry laid” method is based on staple fibers, which are usually separated into individual fibers by carding and then using one aerodynamic or hydrodynamic processes are combined to form the unconsolidated nonwoven.
- thermobonding This is then bonded, for example, to the finished nonwoven by a thermal treatment (the so-called “thermobonding”).
- the synthetic fibers are either heated to such an extent that their surface melts and the individual fibers are bonded to one another at the contact points, or the fibers are mixed with an additive coated, which melts during the heat treatment and thus connects the individual fibers to one another.
- the connection is fixed by cooling.
- all other methods which are used in the prior art for connecting nonwovens are also suitable.
- Spunbond formation starts from individual filaments which are formed by the melt spinning process from extruded polymers which are pressed through spinnerets under high pressure.
- the filaments emerging from the spinnerets are bundled, stretched and laid down to form a fleece which is usually solidified by "thermobonding".
- the process according to the invention is particularly suitable for nonwovens which are produced by the spunbonded or the “dry laid” process.
- the fibers or nonwovens are equipped with the preparation of quaternary esteramine salt, alkglycoside and optionally glycerin by preparing the preparation in the form of an aqueous dispersion, preferably between 5 and 30% by weight of the preparation, based on the total weight of the dispersion, contains, to which fibers or the nonwoven are applied. All methods and machines commonly used in textile technology, for example a foulard, can be used for this become.
- the nonwoven fabric is first brought into contact with the aqueous dispersion in a bath and the nonwoven fabric treated in this way is guided between two rollers, the water being rebounded by the pressure of the rollers.
- the process according to the invention is preferably designed such that the fibers or nonwovens have a coating of preparation in amounts of 0.3 to 1.5% by weight, in particular 0.5 to 1.0% by weight, based on the fiber or nonwoven weight obtained.
- the preparation used in the process according to the invention contains between 50 and 95% by weight, based on the total weight of the preparation, of at least one quaternary esteramine salt of the formula (I).
- preparations containing quaternary esteramine salts of the general formula (II) are particularly preferably used
- Examples of such compounds are methyl N- (2-hydroxyethyl) -N, N-di (tallow acyloxyethyl) ammonium methosulfate or bis (acyloxyethyl) hydroxy ethyl methyl ammonium methosulfate.
- Compounds which contain alkyl radicals having 16 to 18 carbon atoms and whose alkyl chains have 1 to 3 double bonds are particularly preferred. Mixtures of different esteramine salts of the formulas (I) and / or (II) can also be used.
- the preparation used in the process according to the invention contains, in amounts between 5 and 50% by weight, based on the total weight of the preparation, alkyl glycosides of the general formula RO (G) x , in which R is a primary straight-chain or methyl-branched, in particular in 2 Position methyl-branched aliphatic radical with 8 to 22, preferably 12 to 18 carbon atoms and G is the symbol which stands for a glycoside unit with 5 or 6 carbon atoms, preferably for glucose.
- the degree of oligomerization x which indicates the distribution of monoglycosides and oligoglycosides, is any number between 1 and 10; x is preferably 1.2 to 1.4. Preparations which contain alkyl glycosides in amounts of between 5 and 30% by weight are particularly preferred.
- the method according to the invention is preferably so designed that the fibers or nonwovens are treated with a preparation containing glycerin, the preparation containing glycerin in amounts between 1.0 to 15% by weight, based on the total weight of the preparation.
- antistatic agents or lubricants are usually used in amounts of up to 20% by weight, based on the total weight of the preparation.
- the process according to the invention can also be advantageous to design the process according to the invention in such a way that the fibers or the nonwovens are treated with a preparation which, in addition to the components already described, also contains monoesters of glycerol and a C O -C H fatty acid in amounts between 5 and 35 % By weight, based on the total amount of the mixture.
- a particularly preferred monoester is glycerol monolaurate.
- fibers with a hydrophilic finish which contain exclusively or predominantly polyolefins or polyesters or nonwovens which predominantly contain fibers which are produced by the process according to the invention are claimed.
- These fibers or nonwovens show hydrophilic properties, which are preferably retained even after repeated wetting.
- the nonwovens produced according to the invention have "liquid strike through” times of less than 10 seconds and in particular less than 5 seconds.
- liquid strike through times are understood to mean the times that a certain amount of water or Artificial urine is required to reach an absorbent lower layer through the fleece. This time is determined according to the EDANA (European Association of Nonwovens Manufacturers) test method 150.0-84.
- the "liquid strike through” time should be as short as possible in order to ensure that the liquid is transported quickly through the fleece to the absorbent material. In this way, the fleece surface remains dry and thus leads to increased wearing comfort
- the nonwovens produced according to the invention also retain this favorable property repeated use and are further characterized in that they preferably have a "liquid strike through” time of three times, in particular five times, the determination of the "liquid strike through” time according to the EDANA test method 150.0-8, in any case a "liquid strike through” time of have less than 10 seconds, in particular less than 5 seconds.
- the measurements were carried out using a test device with a time logger (Lister tester) from
- test fleece polypropylene spunbond fleece with a
- test fleeces were then one at 70 ° C.
- WIS 150 placed under a layer of the prepared test fleece and then brought into contact with 5 ml artificial urine (1000 ml dist. H 2 O, 9 g NaCl) from the Lister tester. The measurements were carried out at 20 ° C and 65% relative humidity. The time it takes for the liquid to penetrate the fleece was read in seconds on the time log.
- test nonwoven was underlaid with a new layer of filter paper after the first measurement without being dried and the measurement was repeated.
- Nonwovens that were equipped with the following preparations were tested.
- the percentages by weight relate to the total weight of the preparation.
- the respective preparations were used in the form of an aqueous dispersion which contained 20% by weight of active substance, based on the aqueous dispersion.
- the nonwoven equipped with the agent V2 proves that the use of alkyl polyglucoside and glycerol alone does not lead to the desired hydrophilic nonwovens. This proves that only through the suitable combination of quaternized esteramine salt and alkyl glycosides the desired hydrophilic finish is achieved.
