Pressure Batch Dyeing of Polyester Yarn Packages. 

Dyebath/auxil iary bath reuse has been demonstrated on a pilot-scale to be a feasible, economical alternative to conventional batch dyeing processes. Atmospheric disperse dyeing of nylon and polyester carpet and nylon pantyhose, and pressure disperse dyeing of polyester yarn packages have all been demonstrated as suitable candidates for plant incorporation of the reuse techniques.

BORCODYE D-6-LF may be added undiluted into the dyebath at the start of the dyeing cycle and can be applied under atmos-heric or pressure conditions. It is low foaming and yields excellent results on piece goods, yarn, package dyeing and carpet. 

INTEX DETERGENT 261 was developed as a highly efficient scouring compound, particularly for cleaning dyed yarn packages. 

When dyeing in a yarn package machine the dyestuff solution is added at 40°C (104°F) and, whilst the liquor is in circulation, the temperature is gradually raised to that recommended for the application of the dyes. The required quantities of sulphide and soda ash are dissolved separately, filtered, and entered into the machine gradually over a period of 20 to 30 minutes, after which exhaustion may be completed slowly, adding 15 to 25 per cent of common salt according to the shade. 

Pirn Vporn, 2 is also pirn [ME] (15c) n. (1) A wood, paper, or plastic support, cylindrical or shghtly tapered, with or without a conical base, on which yarn is wound. (2) The double-tapered take-up yarn package from drawtwisting of nylon, polyester, and other melt spun yarns. 

Pirn barre A fabric defect consisting of crosswise bars caused by unequal shrinkage of the filling yarn from different points on the original yarn package. 

Pot spinning n. A method formerly used for making viscose rayon. The newly spun yarn was dehvered into the center of a rapidly rotating, centrifugal pot, where it received twist and centrifugal force caused it to go to the wall of the pot. The yarn package so formed was called a cake. 

Traverse length n. The lateral distance between the points of reversal of the wind on a yarn package. 

Tube n. (1) A cylindrical holder or bobbin used as a core for a cylindrical yarn package. (2) A cylindrical yarn package. 

Knitted fabrics are categorized as either weft or warp . Weft fabric is faster and more economical to produce and the process can be accomplished with a single yarn package. The warp knitting process, on the other hand, requires a warp beam, that is, a running sheet of yarns, similarly to weaving. Loops are formed transversely in the weft process and essentially vertically in the warp process (Fig. 1.14). Simplest or plain weft knits tend...
