Problems solved by technology

Due to the limitation of cotton fiber's own material properties, the biggest disadvantage of fabrics woven from pure cotton yarn is that it is flammable and cannot be used as a flame-retardant material.
At the same time, the development of traditional flame-retardant products overemphasizes the flame-retardant function of the final product and ignores the wearability of the product
[0004] China's textile flame-retardant technology began in the 1950s, starting with the study of temporary flame-retardant finishing of cotton fabrics, but the development is slow

Embodiment 1

[0023] A flame-retardant aramid-cotton blended knitted fabric, the product adopts single-side plain weave. Horizontal density: 63 / 10cm; vertical density: 44 / 10cm. Needle size: 12G, knitted on a computerized flat knitting machine. Yarn: 30S / 2 strands are used. Gram weight: 248 grams / square meter.

[0024] 85% flame retardant aramid fiber and 15% cotton are used as raw materials. The flame retardant aramid fiber is high flame retardant aramid fiber. The fine-staple cotton fiber is used as raw material.

[0025] The product process includes:

[0026] 1. Pretreatment of flame retardant aramid fiber: pretreatment → opening and cleaning → carding → pre-drawing → flame retardant aramid sliver;

[0027] In order to avoid static electricity generated in the production process of flame-retardant aramid fiber, which affects production efficiency, the flame-retardant aramid fiber is pretreated with an antistatic agent and placed for more than 7-9 hours to avoid the static electricity...

Abstract

The invention relates to a flame-retardant aramid fiber and cotton blended knitted fabric. 85% of flame-retardant aramid fibers and 15% of cotton fibers are selected as raw materials and spun by adopting a siro spinning and compact spinning combined spinning method and then the fabric is woven. An antistatic agent is adopted to pretreat flame-retardant aramid fibers before spinning, the flame-retardant aramid fibers are placed for 7-9 hours or longer and the yarns are lubricated and waxed during weaving. According to the flame-retardant aramid fiber and cotton blended knitted fabric, the yarnsare formed by blending the flame-retardant aramid fibers and the cotton fibers so that the fabric has the advantages of softness, smoothness and good hygroscopicity of the cotton fabric and has a certain flame-retardant property.

Description

technical field [0001] The invention relates to the technical field of textile manufacturing, in particular to a flame-retardant aramid-cotton blended knitted fabric. Background technique [0002] In recent years, my country's textile flame-retardant technology has developed rapidly, and a large number of new flame-retardant fibers and multi-functional flame-retardant fabrics have come out, but there is still a large gap with foreign countries, especially the high-end market is basically controlled by foreign companies, while my country's self-developed technology still has many difficulties to be overcome. A large number of statistical data at home and abroad show that interior decoration fabrics, bedding, sofas, electric blankets, etc. were once the source of fires. In recent years, my country has attached great importance to the development of flame-retardant textiles. [0003] Although cotton fibers are currently used to make fabrics woven from yarns, they feel smooth an...
