Abstract

The invention provides a leather substrate for a fine eiderdown clothing and the making way for the leather substrate, which is made by interweaving warp and weft yarns. The warp is polynosic viscose rayon, the weft comprises novel polyester microfiber (33-37% by mass) and polynosic viscose rayon (63-67% by mass). The making way for the leather substrate comprises spinning, weaving, dyeing and leveling. The leather substrate is mainly for producing clothing leather. The clothing leather made of the leather substrate is soft, very like true leather, with fine texture, and small shrinkage. The leather substrate changes the idea for producing clothing leather in the past, improves such problems associated with the production of cloth leather substrate as liability to wrinkle, high shrinkage and poor strength, etc., can meet demands from different consumers in the change of clothing leather, and provide wider space for raw materials for the leather-making industry.

Description

Drizzle suede clothing leather foundation cloth and manufacture method thereof

Technical field

The present invention relates to textile field, relate in particular to a kind of drizzle suede clothing leather foundation cloth and manufacture method thereof

Background technology

Artificial synthetic leather be on base fabric coated with resins or dipping polyurethane resin again through arrangement later and make, the performance of leather base cloth has directly influenced the performance of artificial synthetic leather, and production technology, equipment and the quality level of therefore removing from office base cloth is the basis that guarantees the good sustainable development of artificial synthetic leather industry.Can mainly contain woven cloth, knitted cloth, non-weaving cloth and composite fabric four big classes as the material of artificial synthetic leather base cloth.Woven cloth is to be interweaved by the warp of mutual arranged vertical, weft yarn to make, and can be divided into plain cloth, TWILL CLOTH, SATIN AND SATEEN CLOTH and nap fabric four big classes.The employed raw material of woven cloth mainly contains cotton textiles, polyester-cotton blend and polyester-viscose blended yarn, and fabric has good DIMENSIONAL STABILITY, and consumption maximum in polyurethane artificial leather processing is mainly used in and produces footwear leather, fancy leather, clothing leather and luggage leather etc.

The production method of existing woven synthetic clothing leather foundation cloth is: mainly by cotton type polyester staple fiber of 1.4 dawn to 1.5 dawn, cotton, common viscose fiber is spun into warp thread and weft yarn through normal spinning process, produces clothing leather foundation cloth by bleachinging and dyeing with plucking, cropping after routine is weaved.The major defect that existing clothing leather foundation cloth product exists is that easy wrinkle, contraction are big, DIMENSIONAL STABILITY, powerful poor, and the clothing leather lines of making is too thick, and fine and smooth inadequately, the skin sense is not strong.

Summary of the invention

For addressing the above problem, the object of the present invention is to provide a kind of drizzle suede clothing leather foundation cloth.

3) dyeing and finishing process: select for use the liquid starchy enzyme to carry out destarch; Select the dyeing of high strength 300% phoenix plumage sulphur black for use; The washing operation is selected the abundant washing of detergent and soda ash for use, the alkalescence of flush away cloth cover and loose colour; In the soft technology, handle with bleeding agent and fluffing softener; Adopt the oven dry of secondary drying method to dye base.

The mass percent of described novel microdenier polyester fibers is 33%-37%, and the mass percent of rich and powerful viscose is 63%-67%.

Described spinning process comprises the steps:

1) opening or cleaning;

2) comb and parallel cotton fibers prior to spinning: select Bearded-needle knitted cloth AC2515 for use, doff clothing AD4532, the taker-in clothing of flat-clothing MCZ H35 and AT5605, differential surface speed adopts 1.9-2.0;

3) drafting;

4) revolving cup spins: adopt band to bear the CM-2A combing roller card clothing at angle, and 8000 rev/mins of carding speeds, feed plate pressure 26.5 kgfs, relative humidity is between 62%-70%.

The described portion operation of knitting adopts ring temple, thorn is high select for use 0.4mm 0.6mm the coronule combination of 1.0mm.

Described dyeing and finishing process comprises the steps:

1) destarch, dye gigging select for use speed of a motor vehicle 95-100 rice/minute, tension force 5N, 85-90 ℃ of grey cloth last volume destarch temperature was with amylase destarch 42-48 minute;

2) dyeing, selecting 300% phoenix plumage sulphur black dyeing, 1 road charge temperature for use is that 40-50 ℃, 2 road charge temperatures are 90-95 ℃, dyes 42-48 minute;

3) washing earlier becomes washing liquid with efficient detergent and soda ash according to 6: 5 mixed, and per 5 kilograms of detergents add 200 kilograms in water, wash 2 roads with described washing liquid heat, and per pass 30-40 minute, temperature was 50-60 ℃;

4) softness becomes softener with bleeding agent 838 with the mixed of softener MF according to 4: 6 kilograms of fluffing earlier, carries out soft treatment 2 roads with described softener, and per pass 30-40 minute, temperature was 50-60 ℃;

5) oven dry is dyed base and is adopted secondary drying method technology;

6) plucking selects for use the napper card clothing to carry out plucking

Drizzle suede clothing leather foundation cloth of the present invention is mainly used in the production clothing leather, has advantages such as soft, that kishke feel is strong, lines is fine and smooth, contraction is little with the clothing leather of this drizzle suede clothing leather foundation cloth manufacturing.Drizzle suede clothing leather foundation cloth of the present invention has changed the thinking that the traditional dress leather is produced, improved in the clothing leather foundation cloth production problems such as easily wrinkling, shrink greatly, brute force is poor, can satisfy the demand that different consumers change clothing leather, for leather industry provides more wide raw material space.
