Treatment of textile products

Processes of chemical treatment of textile products are a separate branch of producing of above wares likewise mechanical treatment [14]. Their main aim is to give textile products suitable properties facilitating their further treatment and desirable usable features like shape stability. 

Finishing is the subsequent treatment of textile products to attain certain characteristics, for example, flame resistance or dyeing. It is necessary if these characteristics cannot be obtained solely by choosing a suitable raw material or an adequate... 

Commercial products, used widely for the treatment of textiles, mainly apparel, soft furnishings, and carpets, are known under the trade names Scotchgard (3M), Teflon (DuPont), Asahigard (Asahi Glass), and Unidyne (Daikin). This subject is reviewed in detail in Reference 24. 

There are three primary methods for controlling the flammability of textile products. These include the following incorporation of the fire retardant into the fiber during production, wet treatment of the fabric after production, or back-coating the fabric.

It should be noted that in connection with strict measures on environmental protection stock dyeing, as practically wasteless production, becomes the most important among other methods. Besides, due to the shortage of service water there is no longer any necessity for sewage treatment of textile-finishing production from different impurities (dye, surface-active substances (SAS), salts and so on). 

A finish could also be an after treatment for fiber or fabrics. Here, finishes are applied to reduce the damage during processing, promote adhesion to matrix resins, and improve the end properties such as hand (softness), water repellency, and wash-wear characteristic of textile products.

Several approaches have been proposed to implement membrane technology to the treatment of textile waste water from different production streams. Pressure driven membrane operations are traditionally divided into four different types. 

THPOH—Ammonia—Tris Finish. By far the most effective finish for polyester—cotton textiles was a system based on the THPOH—NH treatment of the cotton component either foUowed or preceded by the appUcation of Tris finish to the polyester component. This combined treatment appeared to be effective on almost any polyester—cotton blend. A large amount of fabric treated in this way was sold throughout the United States and much of the rest of the world. Shortly after the introduction of Tris finishing, Tris was found to be a carcinogen. Most of the Tris treated production was in children s sleepwear, and this created a situation in which almost aU chemical fire-retardant-treated textiles were unfairly condemned as dangerous. Manufacturers mshed to replace chemically treated textiles with products produced from inherently flame-resistant fibers. Nowhere was the impact more severe than in the children s sleepwear market. New, safer materials have been introduced to replace Tris. Thus far none has been as completely effective.
