Problems solved by technology

[0003] The existing Chinese patent document (publication number: CN105595488A) discloses an anti-pilling knitted fabric and its preparation method. The fabric is composed of three layers of inner, middle and outer layers respectively composed of different components, and the inner layer is made of cellulose fiber and acrylic fiber. The middle layer is made of polyester fiber, polyester fiber and lignin fiber; the outer layer is made of cotton fiber, hemp fiber and wool blended fiber. Although the knitted fabric can resist pilling, it has poor flame retardancy and requires further improvement

Abstract

The invention discloses a knitted fabric capable of improving flame-retardant performance. The knitted fabric is prepared from the following raw materials in parts by weight: 24 to 30 parts of preprocessed bamboo fibers, 16 to 22 parts of polypropylene fibers, 12 to 14 parts of pure cotton, 8 to 12 parts of needle-shaped wollastonite, 6 to 10 parts of a flame-retardant reinforcing agent, 4 to 8 parts of sepiolite fibers, 2 to 5 parts of sodium silicate, 1 to 3 parts of hindered phenol, 4 to 8 parts of micro-porous bamboo charcoal, and 1 to 3 parts of mullite powder. The invention aims at providing the knitted fabric capable of improving the flame-retardant performance. Compared with the knitted fabric in the prior art, the flame-retardant performance of the fabric is greatly improved. Theknitted fabric provided by the invention has high application value and good application prospect.

Description

Technical field [0001] The invention relates to the technical field of fabrics, in particular to a knitted fabric with improved flame retardancy and a preparation method 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 influence the performance of clothing colors and shapes. In the clothing world, clothing fabrics are diverse and change with each passing day. But generally speaking, high-quality and high-end fabrics have the characteristics of comfortable wearing, sweat-absorbing and breathable, drape and stiff, noble vision, and soft touch. Knitted fabrics use knitting needles to bend the yarn into loops and Fabrics formed by intertwining, knitted fabrics and woven fabrics are different in the form of yarns in the fabric. Knitting is divided into weft knitting and warp knitting. At present, knitted fabrics are ...
