Embodiment 1

[0023] A preparation process for machine-washable cashmere knitted products, comprising the following steps:

[0024] (1) Wash the cashmere with an average length of 45cm and an average fineness of 15μm, and then use a combined cashmere carding machine to card the washed cashmere 6 times in a single pass to obtain a carding length of 39~45mm and a roughness percentage. Cashmere fibers with an impurity content of less than 0.15% and less than 0.2%;

[0025] (2) Add the dye to the chemical tank, add water and stir evenly, adjust the pH to meet the process requirements, raise the temperature to 30°C and transport it to the dyeing vat, add cashmere fiber, and after running for 10 minutes, raise the temperature by 1°C every 1.0min, and control the dyeing temperature to 80°C , the holding time is 65 minutes, after rinsing, it is neutralized with acetic acid, when the pH is around 6, it is drained, and then the cashmere fiber is dehydrated and dried;

[0026] (3) Feed the dyed loose...

Abstract

A worsted machine-washable cashmere knitted product and its preparation process, including fiber raw material selection, fiber raw material pretreatment, spinning worsted yarn, weaving into garment, and garment post-treatment. The present invention obtains cashmere through a special process. The worsted fabrics have better dyeability and high fracture resistance, and at the same time improve the anti-felting performance of the fabrics, so that the finished garments can be machine washed.

Description

technical field [0001] The invention belongs to the technical field of knitting processing, and in particular relates to a worsted machine-washable cashmere knitted product and a preparation process thereof. Background technique [0002] In the field of clothing, thin, fashionable, high-quality, and organic have become the main selection marks of mainstream consumer groups. In order to save time, the public now hopes that high-end clothing can not only be washed by hand or dry-cleaned, but also can be washed in a household washing machine at will without affecting the high-end. Appearance retention and dimensional stability of quality garments. As a high-grade animal fiber, cashmere is slender, soft and warm, and has the reputation of "soft gold". The fineness of cashmere is generally between 14-18.5 μm, and the natural curl is high. It is tight and cohesive in spinning and weaving. , so the thermal performance is excellent. [0003] Cashmere products have always had a pro...
