Preparation method of warm-keeping natural color yak cashmere and alpaca blended fancy fabric

Abstract

The invention provides a method for making warm-keeping natural color yak cashmere and alpaca blended fancy fabric, in which yak cashmere with excellent warm-keeping property is selected as a raw material. According to tests, the warmth retention of yak cashmere is 1.6 times that of cashmere, and the thick needles of the 3G knitting machine are selected to ensure that the fabric is thick and warm. The sliver weight of the carding machine is 4 g / m and the draw frame ensures that the evenness of the roving reaches 2%-5% through the light-weight process, so that the thickness difference of the final product is within 3%. Moreover, the large circle and the heavy brushing process are not only exquisite in appearance, but also ways to increase warmth. Since in this application, the series of different colors are formed by using natural color yak wool and alpaca wool for color matching, it does not need to be dyed, thereby avoiding the chemical residue phenomenon in the dyeing process and enriching the texture of the plush fabric. The variety of colors further expands the use space of plush fabrics, shortens the process flow, improves the grade of finished products, and improves economic and social benefits.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a method for making a warm-keeping natural color yak wool and alpaca blended fancy fabric. Background technique [0002] With the development of textile technology and the improvement of people's living standards, people's awareness of environmental protection has also been continuously improved, leading to higher and higher requirements for sustainable development of clothing in market consumption. As a response to material civilization and spiritual civilization, clothing fabrics are required to be environmentally friendly and comfortable in addition to novel and unique styles.

Problems solved by technology

[0003] In the production process of plush products, they must be dyed. In the process of dyeing and drying, the length and strength of the plush will be damaged to a large extent, which will make the spinnability of the plush fiber worse and the strength of the yarn Reduced, easy to break, reduced thermal performance, and the finished product feels rough, thus reducing the wearing performance of plush products

In addition, the dyeing of plush products produces a large amount of sewage, which pollutes the environment and affects human physical and mental health, especially the hexavalent chromium ions in the dyed sewage are more serious to the harm to the human body, (hexavalent chromium ions can make human cells Carcinogenic highly toxic substances)
