Abstract

The invention relates to a processing method of yarns, belongs to the textile field, and discloses a processing method of dyeing-free yarns. The processing method of the dyeing-free yarns comprises the following specific steps: solvent preparation: mixing pre-prepared padding solution obtained by mixing a strong alkali agent, a softening agent, a breaking agent, sodium chloride and water, and pre-cooling the pre-prepared padding solution to the temperature of 5-15 DEG C; immersing yarns with the padding solution; padding treatment; yarn cleaning; and finished product drying. The invention provides the processing method of the dyeing-free yarns. The steps are reasonable, burrs on the yarns are removed by adopting the breaking agent, thus, surfaces of the yarns are smooth, namely the yarns feel soft without sizing, the problems of slurry pollution and yarn residual slurry are fundamentally solved, moreover, a yarn processing technology is further greatly simplified, meanwhile, the breaking agent comprises substances which are easy to neutralize and harmless to human bodies such as urea and thiourea, the chemical agent can be removed by simply soaking and cleaning the yarns, and the processing course of the yarns is safe and environment-friendly.

Description

technical field [0001] The invention relates to a yarn processing method in the textile field, in particular to a dye-free yarn processing method. Background technique [0002] According to statistics in 2010, among the 39 industries in my country, the chemical oxygen demand (Chemical Oxygen Demand, COD) discharge of the textile industry ranks fourth, with a total of 305,000 tons, of which about 25% comes from desizing wastewater. The main reason for the high COD of desizing wastewater is that it contains a large amount of polyvinyl alcohol (PVA) slurry with high COD and low biodegradability. PVA slurry is difficult to desizing and has poor biodegradability. It accumulates in large quantities after being discharged into water bodies, inhibits and destroys the respiration activities of aquatic organisms, and causes the release and migration of heavy metals in sediments, which in turn causes more serious water pollution. No other size can match or surpass PVA in terms of sizi...
