Problems solved by technology

Generally speaking, during the weaving process of spandex and other elastic fibers, in order to avoid the unexpected elongation of the spandex yarn and the uneven tension that will affect the quality of the elastic fabric, the spandex yarn must be fed by a special fixed-length positive thread feeding device. Strictly control the tension of the spandex yarn during the yarn, and there are certain difficulties in the implementation of industrial production

Embodiment 1

[0027] A method for preparing a suede-like elastic fabric, comprising the following main steps: (1) The raw material is polyester / polyester sea-island type superfine denier fiber filament as the warp direction, and polyester interwoven spandex filament is used as the weft direction for weaving processing. The scheme is as follows: warp direction: polyester / polyester sea-island type ultra-fine denier fiber filament FDY→twisting→setting→warping; weft direction: polyester FDY+spandex→twisting→setting→weft adjustment, and then warp and weft weaving into gray fabric;

[0028] (2) The gray cloth obtained in step (1) is subjected to the following process: open-width scouring → pre-shrinking → pre-setting → weight reduction → dyeing → sanding → napping → shearing → setting; the open-width scouring is first performed with cold water at 20°C Carry out low-temperature scouring for 120 minutes, then scouring in warm water heated to 60°C for 30 minutes, and then high-temperature treatment w...

Embodiment 2

[0041] A method for preparing suede-like elastic fabric, comprising the following main steps:

[0042] (1) The raw material adopts polyester / polyester sea-island type superfine fiber filament as the warp direction, and polyester interwoven spandex filament as the weft direction for weaving processing. The weaving scheme is as follows: warp direction: polyester / polyester sea-island type superfine denier fiber length Silk FDY→twisting→shaping→warping; weft direction: polyester FDY+spandex→twisting→shaping→weft adjustment, and then warp and weft weaving into gray fabric;

[0043] (2) The gray cloth obtained in step (1) is subjected to the following process: open-width scouring → pre-shrinking → pre-setting → weight reduction → dyeing → sanding → napping → shearing → setting; the open-width scouring first uses 35°C cold water Carry out low-temperature scouring for 50 minutes, then scouring in warm water heated to 60°C for 20 minutes, and then high-temperature treatment with 98°C h...

Abstract

The invention relates to a method for preparing suedette elastic fabric. The method comprises the following steps that 1, weaving processing is conducted on raw materials by taking polyester or polyester sea-island type ultra-fine denier fiber filaments as the warp direction and taking polyester woven spandex filaments as the weft direction; 2, open-width scouring, preshrinking, preshaping, decrement, dyeing, sanding, napping, shearing and shaping are conducted on gray fabric obtained in the first step, wherein open-width scouring comprises the steps that low temperature scouring is conducted for 30-120 min through cold water with the temperature ranging from 20 DEG C to 35 DEG C, then scouring is conducted for 20-30 min in warm water with the temperature ranging from 60 DEG C to 70 DEG C, and high-temperature processing is conducted for 8-15 min through hot water with the temperature ranging from 90 DEG C to 98 DEG C. Therefore, uniform shrinkage of spandex in a wet state is guaranteed, and the warp density is increased. The preparation method is simple, convenient and feasible, the raw materials are easy to obtain, the cost is low, and the product quality is good.

Description

technical field [0001] The invention belongs to the technical field of textiles, in particular to a method for preparing suede-like elastic fabric. Background technique [0002] Natural suede has soft luster, soft texture, delicate and comfortable touch, and is deeply loved by people. But the number of suede is extremely limited, and suede is more expensive. With the development of leather tanning technology, people can process sheepskin, cowhide and pigskin as suede. This kind of leather product is also called suede. However, the price of suede processed from sheepskin and cowhide is still very expensive, and limited by its output, it can only meet the needs of a small number of people. Most of the suede currently on the market are some suede-like fabrics. The main raw material of suede-like fabric is sea-island microfiber, and woven fabrics, knitted fabrics and non-woven fabrics can be used as base fabrics for suede-like fabrics. Among them, knitted gray fabrics are div...
