DE2054300C3 - Process for delustering a textile containing acetyl cellulose fibers - Google Patents

Description

There are various ways to remove the shine from acetyl cellulose fibers Methods known. This includes B. boiling the fiber in water or in an aqueous one Solution of phenol and soap. Stretch the fiber in a 35 to 55% acetone solution and wash out the fiber in a mixture of a solvent and a non-solvent. These known methods however, have a number of disadvantages and in particular have not been able to achieve satisfactory results achieve in terms of gloss removal, because this results in a significant deterioration in tear strength and the handle of acetyl cellulose textiles had to be accepted.

In contrast, the method according to the invention for delaminating a textile which contains acetyl cellulose fibers consists in applying an aqueous paste to the textile which contains 0.1 to 25 percent by weight of a hygroscopic substance and 3 to 50 percent by weight of an inorganic acid and / or an aliphatic carboxylic acid contains up to 4 carbon atoms, the paste dries on the textile and then the textile is subjected to steam treatment in saturated or unsaturated steam at 90 to 130 ^° C for 1 to 60 minutes.

In this way, according to the invention, textiles with contrasting surfaces made of glossy and matte material can easily be made by using the textile with the paste Printing plate or printing roller is printed, which shows the desired surface pattern.

The invention also relates to an aqueous paste for delaminating an acetyl cellulose fiber Textiles containing 0.1 to 25 percent by weight of a hygroscopic substance and 3 to 50 percent by weight an inorganic acid and / or aliphatic carboxylic acid having up to 4 carbon atoms Contains thickeners and, if appropriate, customary additives.

The term "acetyl cellulose" includes cellulose diacetate, cellulose triacetate, and mixtures thereof. The term "textile" extends to fibers, game, woven and non-woven as well as knitted or knitted textiles and films. Furthermore, the term "textiles" also extends to materials that consist partly or wholly of acetyl cellulose fibers.

Textiles that contain a synthetic cellulose fiber such as viscose rayon, copper rayon, made with acid is not delaminated and textiles that also contain polyamide fibers, acrylic fibers or polyester fibers, can be treated according to the invention. Woven textiles can also be used containing twisted or doubled yarn.

Examples of suitable inorganic acids which are suitable for the purposes of the invention are phosphoric acid, Hydrochloric acid, sulfuric acid, nitric acid, hydrobromic acid, phosphorous acid and hypophosphorous acid. Of these inorganic acids, phosphoric acid, hydrochloric acid and Hydrochloric acid and sulfuric acid are preferred.

Examples of suitable aliphatic carboxylic acids which are suitable for the purposes of the invention are Monocarboxylic acid such as formic acid, acetic acid or acetic anhydride, propionic acid and butyric acid, Dicarboxylic acids such as oxalic acid, malonic acid, succinic acid, maleic acid and maleic anhydride: and hydroxycarboxylic acid such as lactic acid. Malic acid and tartaric acid. Of these aliphatic carboxylic acids become formic acid. Acetic acid, maleic acid, lactic acid, malic acid and tartaric acid are preferred. For the treatment of cellulose triacetate fabrics, formic acid and lactic acid are particular suitable.

When aliphatic carboxylic acids with a carbon number of more than 4 are used usually both the miscibility with water and the delustering effect are significantly reduced. For this reason, those aliphatic carboxylic acids should be used that do not exceed Contains 4 carbon atoms.

The concentration of this inorganic, aliphatic Carboxylic acids and or mixtures thereof in the paste depend on the nature of the acetyl cellulose fiber and the hygroscopic substance as well as the desired degree of delustering. If the The total acid concentration is less than 3, there is no satisfactory de-gloss effect cause. Even if a concentration greater than 50% is used, the physical Properties of the fiber adversely affected. As a result, a concentration in general Range from 3 to 50%, preferably from 5 to 40% by weight preferred. In any case, concentration should be can be selected within such a range as not to be desirable in strength or others Properties adversely affected. The aliphatic carboxylic acid or the inorganic acid can be used on its own or in a mixture with one another.

The term "hygroscopic substance" includes substances that are produced during steam heating treatment Absorb moisture well and thereby increase the gloss effect. Examples of suitable hygroscopic substances are polyhydric alcohols such as ethylene glycol, diethylene glycol, triethylene glycol, Polyethylene glycol and glycerine hydroxiamines such as ethanolamine, diethanolamine, triethanolamine and urea. The hygroscopic substance has the further advantage that it reduces the strength of the textile to be treated prevented. your

A remote delustered print can be produced according to the invention by using a textile which Contains acetylceliulose fibers, printed with a paste, which is prepared by adding a thickener to a solution of an inorganic acid or a carboxylic acid containing no more than 4 carbon atoms has and a hygroscopic substance, whereupon the textile after an interposed one Drying stage exposed to steam heating treatment. The most suitable Thickening agents can be made by adding one or more natural rubbers or gums with synthetic rubber or rubber such as wheat starch, naphka crystal rubber, sodium alginate, Hydroxymethyl cellulose, gum arabic, gum dragons, carboxymethyl cellulose or polyvinyl alcohol mixed.

The concentration of the thickener should be such that the paste has a viscosity that is suitable for printing and vapor deposition. The intermediate drying to be carried out after 3c the printing is necessary in order to prevent the printing paste from blooming in the subsequent steaming stage; the textile can for Nonnaltemperatur or a temperature up to 100 ⁰ C dried.

The steam heating treatment is done in saturated or unsaturated for 1 to 60 minutes after drying Steam at a temperature of 90 to 130 ° C and preferably in saturated steam 100 to 120 ° C carried out The thickener is removed by touching the textiles after steaming washes enough with water

The de-glossing method according to the invention can after the whitening treatment with a fluorescent Substance or after dyeing the washed cloth to the desired color will. Conversely, the anti-gloss effect desired according to the invention can also be achieved in textiles, which should only be colored after the treatment according to the invention. You can also do that Wash the textile with a detergent at the stage at which the thickener is removed again.
