Background
In recent years, with the continuous development of economy in China and the continuous improvement of the living standard of people, the market demand and the performance requirements of the fabric are higher and higher. Especially, the functional requirements of fabrics for special purposes are more severe. Such as household sofa fabrics, automobile cushion fabrics and clothing fabrics worn by people for outdoor exercises, all of which need to have excellent wear resistance so as to overcome the defects that the appearance is affected due to frequent grinding marks after long-term use, and the service life is shortened due to the phenomena of wear-through, wear-out and the like.
In the prior art, a common method for improving the wear resistance of the fabric is to add a wear-resistant agent into a conventional fabric, wherein the wear-resistant agent is usually a silicon-containing auxiliary agent and has a certain effect on improving the wear resistance of the fabric, but a silicon-containing material is usually poor in compatibility in the fabric and is easy to migrate to the surface of the fabric, so that the bonding of fabric fabrics is influenced, and interlayer separation is caused. Meanwhile, the wear resistance of the material is reduced due to the migration of the wear-resistant agent to the surface. Meanwhile, the strength of the fabric is affected by the addition of the silicon-containing auxiliary agent wear-resistant agent, so that the comprehensive performance of the wear-resistant fabric in the prior art is reduced, and the performance stability needs to be further improved. In addition, the wear-resistant fabric in the prior art has the defects of softness, air permeability, hand feeling, flexing resistance and antibacterial property which need to be further improved.
The Chinese patent with the application number of 201610615337.2 discloses a high-wear-resistance antibacterial sofa cover, which comprises a zipper track, a sofa, cotton fibers, glass fibers and a fragrant bag, wherein the zipper track is arranged at the top of the sofa cover, elastic bands are arranged inside the sofa cover, connecting pieces are arranged on the outer surface of the sofa cover, the cotton fibers are arranged on the outer surface of the sofa cover, snap fasteners are arranged on the outer surface of the sofa cover, the glass fibers and the bamboo charcoal fibers are arranged inside the sofa cover, the glass fibers are arranged on two sides of the bamboo charcoal fibers, a sponge pad is arranged below the glass fibers and the bamboo charcoal fibers, the fragrant bags are arranged on two sides of the sponge pad, and an activated carbon layer is arranged below the sponge pad and the fragrant bags. According to the invention, a high-wear-resistance antibacterial fabric weaving technology is adopted, the polyester low-stretch yarn glass fiber is used as warp yarn, the polyester low-stretch yarn bamboo charcoal fiber is used as weft yarn, and a rapier jacquard is used for weaving the fabric, so that the wear resistance and the antibacterial property of the sofa cover are improved, but the effect of improving the wear resistance of the sofa fabric by only using the rapier jacquard for manufacturing is limited.
Therefore, it is an urgent problem to be solved by those skilled in the art to develop a wear-resistant fabric with excellent comprehensive performance, good wear resistance, softness, air permeability, hand feeling, flexing resistance and antibacterial property.
