Abstract

The invention discloses a biodegradable environment-friendly fabric and a preparation method and product thereof. The biodegradable environment-friendly fabric is made of biodegradable composite fibers through a knitting or machine-weaving process; and the biodegradable composite fibers are prepared from the following raw materials in parts by weight: 60-70 parts of polyethylene terephthalate, 25-32 parts of polybutylene succinate, 10-14 parts of polylactic acid, 5-7 parts of chitosan, and 5-7 parts of fumed silica. The biodegradable environment-friendly fabric is prepared from selected raw materials, the content of each raw material is optimized, the biodegradable environment-friendly fabric made of the biodegradable composite fibers through the knitting or machine-weaving process is highin biodegradation rate, good in biodegradability, environmentally friendly, high in burst strength, (warp direction) high tensile strength close to that of a pure polyester fabric, good in mechanicalproperty, and durable.

Description

technical field [0001] The invention relates to the technical field of textile fabrics, in particular to a biodegradable environment-friendly fabric, a preparation method and a product thereof. Background technique [0002] Fabric is the material used to make clothing. As one of the three elements of clothing, fabrics can not only interpret the style and characteristics of clothing, but also directly affect the color and shape of clothing. Among them, functional fabrics refer to fabrics with certain special properties and uses, such as waterproof, windproof, breathable, moisture-permeable, warm, oil-proof, easy to decontaminate, anti-bacterial and deodorizing, anti-ultraviolet, anti-static, anti-radiation, Anti-flame retardant, high temperature resistance, acid and alkali resistance and other functions. The functional fabrics on the market are mainly clothing fabrics, which are mostly used in outdoor sportswear and high-end casual wear. Among the new functional textile ma...
