Embodiment Construction

[0016] 1 Process flow:

[0017] Raw material--sliver--pre-twisting--stretching--rewashing and drying--needle combing--combing--needle combing--balling--finished product

[0018] 2 The specific production process of stretching blue and purple velvet fibers is as follows:

[0019] (1) Sliver making: combing green and purple velvet fibers 20±1g / m into velvet strips;

[0020] (2) Ply pre-twisting: 5 combed velvet strips are combined, twisted in the Z direction, twist: 4-5T / m, sliver speed: 5.0-5.5m / min; sliver weight: 100±3g / m;

[0021] (3) Stretching: After twisting, the line speed V: 3m / min, the draft ratio D R : 1.75, delivery draft ratio T R : 1.1, temperature: 80°C-100°C;

[0022] (4) Re-washing and drying: feeding number: 12, stripping speed: 2.0-2.5m / min, stripping weight: 65-70g / m2, temperature: 110-120°C, moisture regain after off-machine: 15±1 %;

[0023] (5) Needle comb: combined number: 1, draft ratio: 6.5, stripping speed: 60-70m / min, stripping weight: 10±1g / m...

Abstract

The invention relates to a manufacture technology for drawing short fiber. It contains the following steps: combing, jointing and pre-twisting, drawing, washing and drying, gilling, combing, twain needling, balling and the product would be made. The invention has advantages of sliding, nicety, soft, and would not change the natural feature of cashmere. It has great application value and economic value.

Description

1. Technical field [0001] The invention relates to a production process of drawing short fibers and fibers produced by the process, belonging to the field of textiles. 2. Background technology [0002] The price of high-quality white cashmere is high and the goods are in short supply, reaching a maximum of more than 800,000 per ton. However, the blue and purple velvet with an annual storage capacity of nearly 1,000 tons but relatively coarse fineness has always been in the middle and low-end product range due to poor color quality and end product feel, and the raw material price is only 60-80% of that of white velvet. %, compared with white cashmere, the price difference between the two is larger. If the blue and purple cashmere fibers are pulled to the fineness of white cashmere fibers, they can be used reasonably. [0003] Due to the short length of velvet and purple velvet fibers and short fibers, the tensile strength of the velvet strips is small, and the fibers are eas...
