Description

GERMAN

It is known to refine textile goods, in particular to make them water-repellent, that on the Textile material from spray nozzles or by means of spray guns solutions of stearic anhydride in organic Solvents are applied and the goods treated in this way are left to mature thermally.

This procedure relates to the treatment of non-made-up fabrics. The heat treatment takes place according to this process at temperatures above 35 ° C, preferably above 50 ° C, took place over a period of about 6 hours. In this treatment of unfinished fabrics existed the purpose of the procedure in rendering water repellant; for keeping the shape of the unconfigured There is neither a cause for textile goods, nor did the aforementioned prior art process see such a thing Make it dimensionally stable before, and it would also have at the temperatures used and the specified treatment time a dimensional stability of the treated fabric is not achieved by this process can be.

It is well known that articles of clothing, especially outerwear, are ironed on them lose shape in a relatively short time, especially when it comes to clothing is made of materials that have a more or less large proportion of cellulose fiber. This is true Also for garments, the fabric of which is made using known methods with water repellants has been treated.

It has been found, and surprisingly, that new and worn garments, in particular Outerwear, dimensionally stable and at the same time water-repellent, can be made if the garments after ironing in a chamber provided with suction with a spray of in Treated organic solvents dissolved water repellants and then during a 2 hours not significantly longer exposed to temperatures between 90 and 140 ° C will.

As items of clothing to be treated come into consideration, for. B. Men's suits, women's dresses and Costumes, pleated articles, coats of all kinds, tobacco products (fur coats, etc.), children's clothing and the like. It is irrelevant whether the treatment of such items of clothing immediately after assembly Is made for the first time, or whether the inventive method on garments for Application that have already been worn.

According to the method of the invention, the garments in a conventional ironing process. given shape. The items of clothing are then placed in a chamber and here with them

treated with a spray mist, which consists of a solution of water repellants in organic solvents will be produced. Suitable water repellants for carrying out the process are suitable Textile auxiliaries which are soluble in organic solvents and which have a water-repellent effect of the goods treated with it, such as stearic anhydride or solutions of technical Aluminum oleate in trichlorethylene. For the process according to the invention are not expedient explosive and non-flammable organic solvents such as trichlorethylene or carbon tetrachloride, used.

The spray mist is in a manner known per se through nozzles arranged in the chamber or by means of Spray gun generated. The chamber is equipped with an exhaust system through which the solvent vapors and the excess spray removed for further treatment for reuse. If the items of clothing are treated in a chamber that is closed on all sides, it is appropriate to lead the way by means of a transport device, the individual items of clothing through the one produced with the nozzles Spray through. When working with a spray gun, the item of clothing to be treated becomes Handed into a chamber provided with a glass wall and inserted through an opening with a Spray gun sprays the outer surface of the garment. Following the few minutes Continuous spray treatment exposes the garment to the heat treatment. The applicable Temperatures depend on the type and proportion of synthetic fibers contained in the item to be treated;

Claims (3)

For fabrics made from pure rayon, temperatures of up to 140 ° C can be selected. As has also been found, particularly good success is achieved in the treatment of the garments if the spray mist is injected into the chamber under pressure; Particularly in the case of items of clothing made from tumbled goods, the spray mist injected under pressure penetrates deeper better. Finally, it has been found that the process can be carried out in a particularly economical manner if the heat treatment following the treatment with the spray mist takes place in one or more special drying chambers. The items of clothing treated according to the method of the invention retain the good shape imparted to them by ironing and their water-repellent nature even in the seams, even after months of wear. Claims: 20 1. Process for making garments dimensionally stable and water-repellent, in particular of outerwear, thus identified draws that the garments after ironing in a chamber provided with suction with a spray of known water repellants dissolved in organic solvents treated and then in the chamber for a period not significantly exceeding 2 hours Exposed to temperatures between 90 and 140 ° C. 2. The method according to claim 1, characterized in that the spray mist under pressure in the chamber is injected. 3. The method according to claims 1 and 2, characterized in that the treatment subsequent heat treatment with the spray mist in one or more special drying chambers he follows. Considered publications:
