The precise effects obtained are dependent on the fabric quality, the type of cellulase enzyme and the application conditions, but no mechanical forces are involved in removal of the fibrils. The process has attracted considerable attention and is now one of the main methods of defibrillating lyocell fabrics [94,101-114]. Simultaneous treatment with cellulase and protease enzymes has been applied to the biofinishing of wool/cotton blends [115].

Visual and Manual Tests. Synthetic fibers are generally mixed with other fibers to achieve a balance of properties. Acryhc staple may be blended with wool, cotton, polyester, rayon, and other synthetic fibers. Therefore, as a preliminary step, the yam or fabric must be separated into its constituent fibers. This immediately estabUshes whether the fiber is a continuous filament or staple product. Staple length, brightness, and breaking strength wet and dry are all usehil tests that can be done in a cursory examination. A more critical identification can be made by a set of simple manual procedures based on burning, staining, solubiUty, density deterrnination, and microscopical examination. 

Along with cotton blends, polyester blends with rayon or wool are also important. Wool—polyester blends are widely used in men s suiting materials. For these fabrics, PET staple or tow can be used with a linear density typically about 0.16—0.45 tex per filament (1.5—4 dpf) and a staple length of 50—75 mm (2—3 in.). 

Cotton—Wool Blends. Although they command only a very small fraction of the cotton blend market, cotton—wool blends are easier to make fire resistant than cotton itself. As might be expected, twiU fabrics containing both cotton and wool had decreased burning rates and increased 01 values both before and after fire-retardant treatment (147). 

Ozone is being investigated for shrinkage prevention (182). Wool and blends of wool, cotton, and polyester have been finished to provide improved flame-retardant, durable-press, and shrinkage properties (183,184). Fabrics of these types are often used for uniforms or protective clothing (185). 

TEXAPRET AM is particularly economical on spun rayons, but it is also used as filling finish for cotton, wool and blended fabrics. 

AQUAFILM may be applied to cotton, rayon, nylon, polyester, acrylics, and wool and blends thereof. 

For over a decade NIR quality control has been used in the textile and fiber industries. Perhaps the widest use of NIR has been in the cotton industry. Cotton blending, mercerization, and fiber maturity measurement have been used offline for rapid process control. The wool industry has also employed NIR to measure the residual grease after scouring. Calibrations have been developed for measuring moisture and heat set temperature in nylon yam. Online NIR analysis is being developed for the quality control of the dyeing procedure for carpet yam and for measuring yarn diameter. 

In addition to the garments prepared from woven fabrics, knits (especially single jersey and interlock) are also the major products suitable for garment finishing. The garments prepared from traditional natural fibres or their blends can be suitably processed in garment form. Some specialty fabric types such as blends of wool/nylon and wool/cotton have recently been processed in garment form in order to meet specific market demands of comfort and performance. 

Textiles and carpets are often based on fiber yarns - cotton, wool, or blends, for example cotton/polyester and wool/polyamide - but 100% synthetic fiber yarns also find wide application. Fiber yarns are hardly ever found in industrial applications.
