Description

Process for the Enhancement of Thermostability
The present invention relates to an auxiliary composition and also to a method of improving the thermal stability of natural or synthetic textile fibre materials that are undyed, fluorescent whitened or dyed.
In various textile-processing procedures (pretreatment, application of fluorescent whitening agents, dyeing, finishing), the textile fibre materials are exposed to a heat treatment.
Particularly in the case of goods that are undyed and that may have been fluorescent whitened, this frequently results in undesirable yellowing.
The action of heat also often results in undesirable effects before and after dyeing.
For example, a thermal pretreatment may lead to oxidative damage to polyamide, which manifests itself, for example, in increased yellowing or loss of tensile strength, or which may also have a negative effect on dyeability. Thermal treatment after the dyeing process may likewise result in unacceptable alterations in shade.
It has now been found that the above-mentioned disadvantageous effects can be substantially reduced by the use of a specific textile auxiliary.

Preference is given to compositions comprising, based on the total composition, from 10 to 50 % by weight, especially from 20 to 40 % by weight, of component A, from 44 to 85 % by weight, especially from 55 to 75 % by weight, of component B and from 0 to 75 % by weight, especially from 10 to 60 % by weight, of component C.

The textile fibre materials which can be treated using the method according to the invention may be natural or synthetic fibres and also mixtures thereof. Examples of natural fibres are plant fibres, for example cotton, viscose, flax, rayon or linen, and animal fibres, for example wool, mohair wool, cashmere wool, angora wool and silk. Synthetic fibres are, for example, polyester, polyamide, polyurethane and polyacrylonitrile fibres. The method according to the invention is suitable for the treatment of, especially, polyamide fibre materials.
As polyamide fibre material there comes into consideration natural polyamide fibre material, for example wool or silk, or synthetic polyamide fibre material, for example polyamide 6 or polyamide 6.6, or fibre blends, for example wool/cellulose, polyamide/cellulose, polyamide/wool, polyamide/polyester or, especially, polyamide/elastane blends. The fibre material is preferably synthetic polyamide fibre material.
The textile material can be used in any form, for example in the form of fibre, yarn, woven fabric or knitted fabric.
The auxiliary compositions used in the method according to the invention, comprising the above-defined components A, B and C, are present in the liquor advantageously in an amount of from 0.1 g/l to 100 g/l, preferably from 0.5 g/l to 50 g/l and especially from 1.0 g/l to 40 g/l.
The composition according to the invention can be applied to the textile fibre material by customary dyeing or printing methods, for example by spray application or foam application, by the exhaust process or, preferably, the pad-dyeing process.
Special apparatus is not necessary. It is possible to use, for example, the customary dyeing apparatus, e.g. open baths, winch becks, jiggers or paddle, jet or circulatory apparatus.
In addition to comprising water and the textile auxiliary according to the invention, the liquors may comprise further additives, for example wetting agents, anti-foams, levelling agents, fluorescent whitening agents or agents that influence the properties of the textile material, for example softeners, flame-proofing agents or dirt-, water- and oil-repellents and also water- softeners and natural or synthetic thickeners, e.g. alginates and cellulose ethers.
As mentioned above, the method according to the invention can advantageously be used for the thermal stabilisation both of undyed textile fibre material (white goods), which may have been treated with a fluorescent whitening agent, and of dyed textile fibre material. In the case of undyed or fluorescent whitened textile fibre material, the yellowing caused by heat treatment during heat-setting (hot air) or during moulding processes (contact heat) is prevented or reduced.
The method according to the invention is especially effective in the treatment of fluorescent whitened textile fibre material.
In the thermal stabilisation of dyed textile fibre material, the composition according to the invention can be applied before, during or after dyeing.
When the composition is used before dyeing, yellowing of the undyed goods during so-called pre-setting can be prevented or reduced.
The composition according to the invention is preferably applied after dyeing of the textile fibre material with reactive, acid, metal complex or disperse dyes.
The after-treatment of the dyed textile fibre material with the textile auxiliary according to the invention brings about especially a certain degree of fibre protection during post-setting (heat setting) and effectively reduces the alteration in shade that frequently occurs in that process step, that is to say the shade remains constant, there is no dulling and no loss of colour strength.
In the case of undyed or fluorescent whitened textile fibre materials, no appreciable reduction in whiteness is observed after the treatment with the composition according to the invention.
It has also been found that, surprisingly, the treatment of the textile fibre material with the composition according to the invention also brings about an improvement in fastness to ozone, NOx and chlorine.
The invention accordingly relates also to a method of improving the fastness to ozone, NOx and chlorine of natural or synthetic textile fibre materials that are undyed, fluorescent whitened or dyed with reactive, acid, metal complex or disperse dyes, wherein the fibre material is treated with a liquor comprising a composition comprising the above-mentioned components A, B and C. So-called storage yellowing, that is to say the yellowing that occurs during storage of the textile materials, can surprisingly also be effectively reduced by treatment with the composition according to the invention. Resistance to storage yellowing is generally measured using the Courtauld yellowing test.
The Courtauld test, developed by the Courtauld company and further developed by Marks & Spencer, is an established test in the textile industry for assessing the sensitivity to yellowing caused by phenolic antioxidants.
The textile fibre materials treated with the composition according to the invention have a high Courtauld's fastness.
The compositions according to the invention may comprise as further additives, for example, wetting agents, dispersants or pH regulators.
