Definitions

• the invention relates to a textile finishing agent and process for finishing cellulose-containing textile goods.
• low-formaldehyde crosslinking agents are usually used to refine textile fabrics made from cellulose fibers.
• dimethylolurea compounds used in the past - and sometimes still today - they have the advantage that the free and bound formaldehyde on the goods could be reduced.
• Formaldehyde-free crosslinkers based on N, N′-dimethyl derivatives of glyoxal monourein are currently on the market. Compared to conventional N, N'-dimethylol compounds, these products have a much lower reactivity on the cellulose fiber and significantly higher equipment costs. Comparative equipment with low-formaldehyde reactant crosslinkers has shown that the effects achieved do not correspond to the usual standard.
• the invention is therefore based on the object of providing a formulation for the high finishing of textile goods, in the use of which no formaldehyde is split off, but the application properties of the treated textile goods are nevertheless not adversely affected.
• the dialdehyde used is preferably 1,2-ethanedial or 1,5-pentanedial, which is usually used in aqueous solution.
• the reaction product from the dialdehydes with polyols is prepared by combining the components, if appropriate in an inert solvent, preferably water.
• the pH of the mixture is adjusted to 3-4, e.g. by adding acids (HCl, H2SO4, H3PO4 and the like) or, when using strongly acidic dialdehydes, by adding inorganic or organic bases (e.g. NaOH, KOH, mono-, di- or triethanolamine).
• Dialdehyde and polyol can be used in different amounts.
• the weight ratio of dialdehyde to polyol is preferably 70:30 to 30:70.
• the polyol is preferably used in a deficit so that a mixture of dialdehyde and reaction product is obtained.
• the polyols used are preferably linear C1-C6 diols, in particular those of the formula (I) above, in which R1 and R2 represent a hydrogen atom and the polyols of the general formula (II) above, wherein x, y and z are 0 or 1 stand.
• Particularly preferred polyols are glycol, propylene glycol, 1,4-butanediol, 1,6-hexanediol, neopentyl glycol, glycerin, pentraerythritol and 2-ethyl-2-nitro-1,3-propanediol.
• polymer two types are possible, namely film-forming polymers and self-crosslinking polymers which are customary in the field in question here, and copolymers thereof which have a glass transition point of from -40 ° C. to +10 ° C.
• the polymers can be selected from polyacrylates, polyurethanes, polyamides, polyaminoamides, polyvinyl acetates and polysiloxanes.
• the film-forming polymers are drawn onto the fiber in a conventional manner without forming a chemical bond with the fiber.
• the self-crosslinking polymers are those which are capable of reacting with the textile fiber to form a chemical bond under the finishing conditions (approx. 120 to 160 o C).
• Such self-crosslinking polymers therefore generally contain functional groups, such as free ester groups, hydroxyl groups, amino groups, isocyanate groups and the like, which can react with functional groups of the textile fiber.
• Preferred polymers are: - Polyacrylates and copolymers thereof, for example butyl acrylate / vinyl acetate, ethyl acrylate / vinyl acetate, 2-ethylhexyl acrylic / vinyl acetate, butyl acrylate / vinyl acetate / maleic acid, butyl acrylate / vinyl acetate / maleic acid ester or butyl acrylate / acrylic acid polymers.
• - Polyvinyl acetates and copolymers thereof for example the polymers already mentioned and a vinyl acetate / ethylene polymer.
• the polymers serve to reduce the yellowing problems which arise in the finishing of textile fibers and to give the fibers protection, i.e. to reduce the loss of tear strength associated with the finishing.
• the agent according to the invention further contains a catalyst which serves to bring about a reaction (crosslinking) of the cellulose fibers with the participation of the dialdehyde or its reaction product.
• Suitable catalysts are acidic metal salts, especially magnesium and aluminum halides or mixtures thereof. If the catalysts are used in a mixture, the mixing ratio (in parts by weight) can vary within a wide range. For the particularly preferred catalyst mixture of magnesium chloride and aluminum chloride (including all basic aluminum chlorides), it is, for example, in the range from 100: 0.5 to 100: 30.
• the agent according to the invention can also be present in two or three parts which are only put together when in use.
• the agent is preferably in two parts, the first part containing the components a) and b) mentioned and the second part containing the component c).
• the catalyst is preferably combined with components a) and b) directly or in the liquor immediately before use of the agent according to the invention.
• Components a) to c) according to the invention are preferably used in the following weight ratio: a) Dialdehyde or its reaction product 10-40 parts by weight b) polymer 5-25 parts by weight c) catalyst 5-15 parts by weight
• compositions according to the invention can also contain stabilizers which serve to make the composition stable in storage and homogeneous if self-crosslinking polymers or copolymers are contained therein.
• Suitable stabilizers are, for example, polyols of the above formulas (I) and (II) and polyglycols of the formula HO (CH2-CH2-O-) K -CH2-CH2-OH, in which k stands for 100 to 6000.
• the polyols of the formula (II) and the polyglycols mentioned are preferred.
• the stabilizer is generally present in the composition in proportions of 1 to 10 parts by weight.
• the agent according to the invention can contain a hydrophobizing agent in order to make the textile material hydrophobic.
• the hydrophobizing agent is preferably added to the first part of the agent according to the invention.
• hydrophobizing agents for example paraffins in the form of an emulsion, in particular metal salts of higher fatty acids, such as aluminum or zirconium stearates, or aminoplasts.
• the hydrophobizing agent is generally contained in the composition in proportions of 1 to 15 parts by weight.
• the agents according to the invention can also contain conventional additives, e.g. Surfactants or other additives used in the fleet.
• the crosslinker component a) of the agents according to the invention has a higher reactivity to the cellulose fiber than the previously known formaldehyde-free crosslinkers, such as N, N'-dimethyldihydroxyethyleneurea, and a reactivity comparable to the dimethylolurea compounds. This also achieves comparable effects in terms of dry and wet crease recovery, tensile and tear strength as with conventional low-maintenance equipment.
• crosslinker component a) according to the invention can also be combined by the presence of a stabilizer use with self-crosslinking polymers without fear of instability and inhomogeneity of the agent or of the liquor in which the agent is dissolved.
• the invention also relates to a process for finishing cellulose-containing textile goods, which is characterized in that a liquor is prepared by dissolving the two parts of a textile finishing agent according to the invention, if appropriate together with conventional additives, in water, impregnating the textile goods with the liquor and drying them and subjected to heat treatment for condensation.
• the agents according to the invention are present in the liquor in an amount of about 0.2 to 1.5% by weight, based on the total weight of the liquor.
• the pH of the liquor is generally 2.0 to 6.0, in particular 2.5 to 4.0.
• the liquor can contain other additives customary for the finishing of cellulose-containing textile goods, such as plasticizers, surfactants, antistatic agents, additional hydrophobizing agents, anti-slip agents and the like.
• the textile goods are then impregnated in a customary manner, for example by padding and squeezing the textile goods to a liquor absorption of about 60 to 100%.
• Tables 1 and 2 below show the composition of the agents used and the fleet.
• the liquor was produced by adding the two parts of the agent according to the invention and optionally the stabilizer to the liquor.
• the goods to be equipped were padded in the liquor, squeezed to 80% liquor absorption and shock-condensed at the temperature specified.
