Good lot-to-lot shade correlations were also obtained with reuse of low-temperature reactive dyebaths and fixation baths on 100% cotton, and with reuse of combined high-energy reactive/disperse dyebaths and fixation baths on cotton/polyester knit fabrics. Further computer program development is required, however, before industrial shades can be matched with the reactive dye reuse system. 

In cold pad-batch dyeing of cotton knit goods with REMAZOL dyes, EMIGEN DPR-A is used to increase the pick-up in combination with the wetting agent and to prevent the uneven distribution of the dyes solution during the reaction time. The appearance of the fabric is generally improved.

Mercerization improves dimensional stability of cotton woven fabrics [63]. When knitted fabrics are compared with respect to their relative openness, temperature increases can be said to improve mercerization because when the goods are bleached and then mercerized, the fabric becomes more dense. However, when unbleached fabrics are mercerized, the fabrics become more open [64]. Mercerization also gives moderate improvement in crease recovery of cotton fabrics [65] as well as some protection against the decrease in tensile strength caused by easy-care finishing. 

There are three methods to remove surface fibres from 100% cotton woven and knit goods, namely singeing in the greige state and bio-polishing. The third method is home laundering the fabrics using detergent that contains a cellulase enzyme. 

Sodium chlorite, because of its quick action and ability to bleach cotton which has not been caustic boiled, is well suited for continuous processes. It is used to an increasing extent for bleaching knitted fabrics, and it is claimed that there is substantial economy in the consumption of chlorite, especially in comparison with treatment in a winch. Man-mad fibres require quantities of about 0-15 to 0-2 per cent of sodium chlorite on the weight of the goods. With regard to cotton there appears to be little information, but it is probable that between 1 and 1-5 per cent of sodium chlorite is required. It is also necessary to add an activator to bring the/>H to between 3-5 and 4 either before or during the dwell period in the J box. 

Softener for cotton knit goods, shirtings, sheetings, and yams. 

According to American and European law, it is not compulsory for manufacturers of textile goods to indicate the synthetic component on the label of a product if it is less than 5% [14], The same practice is applied in South Africa. A label may thus indicate 100% cotton, even though a synthetic component is present. As inferred from the stmcture of the warp knitted terrycloth (figure 2), the synthetic component plays a vital role in the durability of the towels, especially where breaking strength in the warp direction is concerned. 

The durability of textile goods is determined to a large extent by the wear and toughness of the textile yams [31], Durability is defined as the preservation of the physieal integrity, appearance and functionality of a product imder normal circumstances of usage [14][21], This has led to the question of whether there is a difference in the effect of industrial laimdering procedures on durability of the cotton/nylon and cotton/polyester warp knitted tenycloth towels.
