Detailed Description

In order to provide a better understanding of the present utility model, the present utility model will be further described in detail with reference to the drawings and embodiments.

The cold-expansion breathable suede-proof fabric comprises a cold-expansion fabric outer layer 1 and a breathable thermal fabric inner layer 2 which are in composite connection, wherein the cold-expansion fabric outer layer 1 is woven by cold-expansion yarns, the cold-expansion yarns comprise nylon core yarns 11 and cold-expansion layers 13 arranged outside the nylon core yarns 11, and cold-expansion particles 15 and ore particles 16 are arranged outside the cold-expansion layers 13 through secondary spraying. The cold expansion layer 13 is a PU foaming adhesive layer, and the cold expansion particles 15 are particles formed by spraying PU foaming adhesive. The PU foaming adhesive, namely polyurethane foaming adhesive, has the characteristic of thermal shrinkage and cold expansion of polyurethane, and the volume of the PU foaming adhesive changes along with the temperature change within a certain temperature range. Specifically, when the temperature is increased, the polyurethane is subjected to thermal shrinkage, the volume is reduced, and when the temperature is reduced, the polyurethane is subjected to cold expansion, and the volume is increased. The ore particles 16 may be mica crystals, jade or composite ore, for example, mica crystals, which have good heat conduction properties, and when the external temperature is low, the mica crystals can rapidly conduct low temperature to the cold expansion layer 13 to cause volume expansion. An antibacterial coating 3 is arranged outside the outer layer 1 of the cold expansion fabric, and the antibacterial coating 3 is formed by spraying nano silver paste, so that the cold expansion fabric has a good antibacterial and bacteriostatic effect and simultaneously has antistatic capacity.

The breathable thermal fabric inner layer 2 is formed by knitting blended yarns, and the blended yarns comprise Modal yarns 21, acrylic heating yarns 22 and bamboo fiber yarns 23 which are twisted and wound outside the Modal yarns 21. The modal yarn 21 is a man-made cellulose fiber yarn, has good softness and excellent hygroscopicity, and has good effects of keeping warm, ventilation, bacteriostasis and deodorization when being combined with the acrylic heating yarn 22 and the bamboo fiber yarn 23 to form a blended yarn. The inner side of the inner layer 2 of the breathable thermal fabric is provided with a napping layer 5 through a napping process, and the outer side of the napping layer 5 is provided with an antistatic layer 51 through spraying. The napping layer 5 is composed of dense fluff, can better block down from penetrating, and can also play a better role in keeping warm. The antistatic layer 51 is formed by spraying a water-soluble polyurethane solution mixed with graphene, and has an inner and outer dual antistatic effect by being matched with the antibacterial coating 3, so that the problem that the down jacket fabric is easy to generate static electricity is solved well.

As a preferable scheme, the waterproof breathable film 4 is compounded outside the antibacterial coating 3. The waterproof breathable film 4 has waterproof and breathable performances, so that the fabric has the capability of coping with severe weather, and meanwhile, keeps good breathability, and is comfortable to wear. The preferable thickness ratio of the outer layer 1 of the cold expansion fabric to the inner layer 2 of the breathable thermal fabric is 1:1.3-1.5.

By adopting the cold-expansion breathable suede-proof fabric as the fabric of the down jacket, the waterproof breathable film 4 can bring better waterproof and outdoor wearing experience to the down jacket. The outer layer 1 of the cold expansion fabric is woven by cold expansion yarns, and due to the design of the surface cold expansion particles 15 and the ore particles 16, the fabric has micropores for preventing velvet from running and has better air permeability. At lower temperature, ore particles 16 conduct low temperature to cold expansion layer 13 fast, and cold expansion layer 13 and cold expansion particles 15 volume expansion further reduce the space between the yarns, make down jacket have more excellent ability of preventing running down and wind-proof ability when using in winter. The inner layer 2 of the breathable thermal fabric is knitted by blended yarns, and has good effects of thermal insulation, ventilation, bacteriostasis and deodorization. The napping layer 5 is composed of dense down, can better prevent down from penetrating, further has the effect of preventing down from running, and has better warm-keeping effect.
