Problems solved by technology

Although the blending of spun silk and wool can improve its spinnability, but the spun silk has high elongation and the proportion of spun silk in the raw material is high, it is difficult to produce and spin the yarn with wool worsted processing equipment according to the ordinary process, and it is difficult to under-stretch. Big, easy to undercut, appear hard ends, increase yarn defects

Embodiment Construction

[0009] The production method of the spun silk wool blended worsted fabric with the content higher than 50% in this embodiment is to make the fabric through the process of variety design, strip dyeing, combing, spinning, weaving, repairing and finishing.

[0010] 1. Yarn variety design

[0011] Raw material composition: wool 48%, spun silk 52%; yarn count: 55Nm / 1, twist: 1200ZT / m, density: 334×284 / 10cm, weight: 180g / m 2 . The length of the fleece is approximately 80mm with a discrete 36% length.

[0012] 2. Silk raw material processing

[0013] Use a stretching machine to break the spun silk, use silk spinning and carding equipment to card the spun silk, and make the spun silk strips with a length of 88mm to 90mm to make an average fiber length of about 43mm, a discrete length of 48%, and a grammage of 6g / m of silk velvet. The silk velvet strips with a fiber length less than 30mm accounted for 25% of the total spun silk velvet strips.

[0014] 3. Strip dyeing and combing p...

Abstract

The invention relates to a manufacturing method for spun yarn and wool blended single-warp-and-single-weft yarns in content of higher than 50%. Through slub dyeing recombing, spinning, weaving, and finishing, a fabric is made. Mass percent of wool in a spinning material is 50% to 60%. Mass percent of spun yarns is 40% to 50%. A spun yarn raw material is processed, a breaking machine is used to snap the spun yarns, and the spun yarn raw material is made into spun yarn woolen strips whose average length of fiber is 40 mm to 50 mm, length dispersion is smaller than 50%, and gram weight is 5 to 8 g / m. The percentage of the spun yarn woolen strips whose fiber length is smaller than 30 mm in the total amount of the spun yarn woolen strips is smaller than 30%. Since the lengths and length dispersion differences of the spun yarn woolen strips and the wool are large, the spun yarn woolen strips and the wool are fine in thickness, high in static electricity, and tensile property of the spun yarns is good, so spinnability can be improved, and evenness quality can be effectively ensured, and yarn faults are reduced. The fabric produced by the method is made of natural fibers, and the fabric has good hygroscopicity and heat retention property, and has spun yarn style and cashmere hand feeling.

Description

[0001] This application is a divisional application, the application number of the original application is: 201210397078.2, the application date is 2012-10-18, and the invention name is "Production method of silk wool blended worsted fabric". technical field [0002] The invention relates to a spinning method, in particular to a spinning method of blending spun silk and wool with a content higher than 50%, and belongs to the technical field of textile manufacturing. Background technique [0003] Worsted fabrics use a wide range of raw materials, commonly used are one or more of polyester, viscose, nylon, spun silk, cashmere, tussah silk, tencel, mohair, acrylic, hemp and other raw materials for blending with wool. With the development of the times and the continuous improvement of living standards, consumers have higher and higher requirements for worsted fabrics. Natural, green ecological, healthy, safe and comfortable fabrics are the first choice of consumers. Because wool...
