Embodiment 1

[0019] Variety 214 / 4 pure capillary wool 200 kg, color number 2225 maroon, equipment: jet dyeing machine made in Japan.

[0020] The two processes of chlorination treatment and resin treatment are completed by the following steps: (wherein the percentage is calculated by the weight of plush yarn)

[0021] (1) Wash with water at 40°C for 10 minutes;

[0022] (2) Treat in 14 kg of sodium dichloroisocyanurate liquid for 20 minutes;

[0023] (3) Put in 14 kg of sodium bisulfite and keep it at a temperature of 55°C for 30 minutes;

[0024] (4) Change the water;

[0025] (5) Dyeing;

[0026] (6) Put in 12 kg of silicone resin and keep the water temperature at 40°C for treatment

[0027] 40 minutes;

[0028] (7) Dehydration and drying.

[0029] After the shrink-proof treatment is completed, the shrink-resistant processed product is obtained.

Abstract

A technology for the antishrinking treatment to knitting wool includes chlorination and resin treating steps. Its advantages include high effect (less than 8% for shrinkage of the international standard), high quality of treated knitting wool, no influence to colour fastness of knitting wool, and retaining the inherent feature of wool fibre.

Description

technical field [0001] The invention relates to a process for anti-shrinkage treatment of pure plush yarn by chlorination and resin method. Background technique [0002] With the continuous development of the market economy, people's consumption habits are also constantly changing, and the demand for material culture is constantly improving and increasing. However, a small amount of wool textile products have problems of pilling and felting. This is because the wool fiber is slender, solid, approximately cylindrical, the outer layer is covered with scales, the inner layer is the cells of the cortex, and the central layer is the medullary cavity called the medulla. Scales are sheets of cells, like fish scales. The directional friction effect caused by the structure of the wool scale layer and the elastic characteristics of wool cause pilling and felting problems in a small amount of wool textile products. There is currently no good solution to this problem. Contents of t...
