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 1）

[0010] The production method of the spun silk and wool blended worsted fabric of this embodiment is made into a fabric through the process of variety design, strip dyeing, combing, spinning, weaving, repairing and finishing in sequence.

[0011] 1. Yarn variety design.

[0012] Raw material composition: wool 50%, spun silk 50%; yarn count: 55Nm / 1, twist: 1200Z T / m, density: 334×284 / 10cm, weight: 180g / m 2 . The length of the fleece is approximately 80mm with a discrete 36% length.

[0013] 2. Silk raw material processing.

[0014] 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.

[0015] 2. Strip dyeing and combing process.

Embodiment 2）

[0023] The remainder of the production method of the spun silk wool blended worsted fabric of the present embodiment is identical with embodiment 1, and difference is:

[0024] 1. Yarn variety design.

[0025] Raw material composition: wool 60%, spun silk 40%; yarn count: 120Nm / 2, twist: 950Z / 1150ST / m, density: 409×348 / 10cm, weight: 205g / m 2 .

[0026] 3. Spinning process.

[0027] After the process of VSN mixed sliver-VSN head needle-VSN two-needle-SHS three-needle-FM20P roving-FM20S roving-COGNETEX four-roller spun yarn-steamed yarn-self-winding-doubling-double twisting-steamed yarn process, it is made for Two-ply yarn for weaving worsted fabrics.

[0028] For two-for-one twisting, the two-for-one twister yarn unwinding mechanism (patent application No. 201220057701.5) and the two-for-one twist yarn production tension device (patent application No. 201020513293.0) to reduce the end-up breakage rate of high-count yarn double twist.

Abstract

The invention relates to a production method for spun-silk wool blended worsted fabrics and relates to the technical field of textile manufacture. The method comprises top dyeing and recombing, spinning, weaving and after treatment to manufacture the fabrics successively. The mass percentage of wool in spinning raw materials accounts for 50% to 60%, the mass percent of spun silks ranges from 40% to 50%, the spun silk raw materials are machined and are broken through a breaking machine to be manufactured into spun silk velvet strips with the average length between 40mm and 50mm, the length discretion smaller than 50%, and the gram weight ranging from 5g / m to 8g / m. The spun silk velvet strips with the fiber length smaller than 30mm account for less than 30% of the total spun silk velvet number. According to the production method, the spun silk content is high, the spinnability is good, the yarn levelness quality is guaranteed effectively, and yarn faults are few.

Description

technical field [0001] The invention relates to a spinning method, in particular to a spinning method for blending spun silk and wool, and belongs to the technical field of textile manufacturing. Background technique [0002] 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 and silk are natural fibers, silk and wool blended fabrics have good moisture absorption and warmth retention properties, and silk contains a variety of amino acids needed by the human body, which has health care functions and is favored by consumers. The average fineness ...
