A kind of double-layer air layer pure separation follow-up cutting fabric

Abstract

The invention relates to the technical field of shell fabric weaving and specifically relates to a double-layer air layer pure separation shell fabric capable of being tailored at will. The double-layer air layer pure separation shell fabric an upper-layer plain single face and a lower-layer plain single face, wherein the upper-layer plain single face and the lower-layer plain single face are woven from 20 D asahi kasei spandex and 40 S / 1 toyobo acrylic fiber yarns, the upper-layer plain single face and the lower-layer plain single face are woven and connected together through spandex betweenthe upper-layer plain single face and the lower-layer plain single face, an a thermal-insulation air layer is formed between the upper-layer plain single face and the lower-layer plain single face, the spandex is chosen from asahi kasei 30 D spandex, and the double-layer air layer pure separation shell fabric capable of being tailored at will is woven by a six-way circular weaving method. The double-layer air layer pure separation shell fabric disclosed by the invention has the advantages that upper-layer gray cloth and lower-layer gray cloth are connected through the spandex, no chemical adhesion aid is utilized, and environmental friendliness and hygiene are achieved; the double-layer air layer pure separation shell fabric disclosed by the invention is of a unique lock structure, so thatthe shell fabric can be tailored at will, and the problem of hemming of the shell fabric after being tailored is solved; the thermal-insulation air layer is formed between the two layers of cloth, sothat the fabric has more thermal insulation and good breathability.

Description

technical field [0001] The invention relates to the technical field of fabric weaving, in particular to a double-layer air layer purely separated random-cut fabric. Background technique [0002] At present, the thermal knitted fabric market mainly achieves the thermal effect through three methods: 1. Increase the thickness of the fabric itself; 2. Use scientific principles to increase the air layer of the double-sided fabric to achieve the thermal effect; It is mostly acrylic blended yarn. The latter two processing methods require high production technology and the cost of raw materials is too expensive, so most of the market adopts increasing thickness to achieve the effect of warmth retention. However, due to the limited thickness of knitted fabrics, most of the market adopts the method of bonding to make two finished products on one side. Cloths are bonded together to achieve thicker garments and better warmth retention. However, this process cannot be tailored to suit t...

Problems solved by technology

The latter two processing methods require high production technology and the cost of raw materials is too expensive, so most of the market adopts increasing thickness to achieve the effect of warmth retention. However, due to the limited thickness of knitted fabrics, most of the market adopts the method of bonding to make two finished products on one side. Cloths are bonded together to achieve thicker garments and better warmth retention. However, this process cannot be tailored to suit the shape, and there are also defects. 1. Chemical glue additives are used for bonding, which is not environmentally friendly; 2. After the use of glue, the weight of the cloth itself will increase, thereby increasing the manufacturing cost of the garment; 3. The use of glue will make the cloth feel hard, lose the air layer in the middle, have poor air permeability, and the comfort of the garment is not enough; 4. Existing fabrics After cutting, the problem of selvage edge curling is serious, which brings troubles to the garment factory; 5. After processing the finished garment, the detachment is large and the service life is short
