Embodiment 1

[0016] The method for mercerizing and anti-shrinkage finishing of wool fabrics of the present invention comprises the following steps:

[0017] Step 1: Wash and fluff woolen fabrics; woolen fabrics include woolen sweaters, woolen trousers, woolen scarves, woolen scarves, woolen socks, woolen gloves, woolen hats, woolen squares, etc.

[0018] The second step: chlorination or chlorination plus oxidation scale; according to the weight ratio of wool fabric: water is 1:30, prepare water in the container wool fabric scale machine, adjust the water temperature at 20-30 °C, use acetic acid, formic acid Or hydrochloric acid to adjust the pH value to 3-5; then put the wool fabric into the wool fabric peeling machine, stir, penetrate evenly, and then add the chlorinating agent sodium dichloroisocyanurate (DCCA), the dichloroisocyanuric acid When sodium is added, it should be completely dissolved in cold water, and slowly added along the cylinder wall of the wool fabric peeling machine. ...

Abstract

The invention discloses a mercerizing and shrinkproof finishing method for a wool fabric, which comprises the following steps of: step one, washing fluffiness of the wool fabric; step two, scale stripping by chloridizing or chloridizing plus oxidizing; step three, reduction dechlorination, in which a reducing agent is added into a container; step four, alkali washing neutralization; step five, water washing; step six, softening and fluid removal; and step seven, dehydration and drying. The method is characterized in that: 1. the whole process of the process is finished in water environment, which is suitable for uniform processing of ready-made clothes and has good reproducibility; 2. the appropriate stripping of wool scales improves dimensional stability and achieves the aim of machine washing; 3. the method combining the chlorination and the oxidization greatly reduces the yellowing of the fabric; and 4. the method greatly improves hand feel and luster, and meets the requirement of people on the comfort and beauty.

Description

technical field [0001] The invention relates to a finishing method for wool fabrics, in particular to a mercerizing and shrink-proof finishing method for wool fabrics. Background technique [0002] Wool is an important raw material for the textile industry. It has many excellent properties, such as good elasticity, strong moisture absorption, not easy to stain, good warmth retention, and soft luster. These properties make wool fabrics have various unique styles and are loved by people. Wool is a kind of natural protein fiber. On its surface, there is a layer of overlapping scales mainly composed of keratin like fish scales. Due to the different friction coefficients in the forward and reverse directions of the scales, when the woolen sweater is worn, the external force is repeatedly applied. Wool fibers will interpenetrate, entangle, interweave, and feel together to produce fluffing. On the one hand, milling makes the wool fabric have beautiful appearance, rich and soft fee...
