Problems solved by technology

Compared with its main component (melamine), the fiber improves the mechanical properties of the fiber and improves the wearing performance of the fabric, but its spinnability is poor, the product yield is low, and the dyeing performance of the product is not good
CN (02154960.5) discloses a flame retardant fiber and its manufacturing method. The fiber is a fiber treated with a flame retardant. Although it has flame retardant properties, its mechanical properties and wearability are not ideal, and its The flammability will also decrease with the increase of washing times
At present, more and more meta-aramid fiber flame-retardant fabrics invented and industrially produced by DuPont in the United States have been introduced in China. This fabric has good flame-retardant and mechanical properties, but there are great limitations in practical applications: price Higher, unacceptable to the majority of users; the appearance quality of the product is poor, the drapability is not good, so the wearing performance of the product is poor; the dyeing performance of the product is limited

Embodiment 1～3

[0028] Take aramid 1313 fiber and flame-retardant viscose fiber with specifications of 1.8D*90mm and 1.5D*90mm respectively, and blend the two fibers in different ratios. The weight ratio of the fibers is shown in Table 1:

[0029] Example

[0030] The blended flame-retardant fabric listed in Table 1, from fiber to fabric, includes three processes: spinning, weaving, and finishing. In the spinning process, the yarn count is 30 s ~70 s / 2; In the weaving process, the warp yarn density is 180-300 strands / 10cm, and the weft yarn density is 150-260 strands / 10cm.

Embodiment 2

[0032] A comparison example of the performance of the flame-retardant fabric prepared by the process described in Example 1 and the flame-retardant fabric of the same specification produced abroad.

[0033] Test items

[0034] Thermal stability shrinkage

[0035] It can be seen from the above table that the blended fabric of domestic aramid fiber and flame-retardant viscose fiber has excellent flame-retardant performance and wearing performance, the fabric has good appearance and feel, dimensional stability, good wear resistance and chemical resistance. Compared with the fabric Nomex III, because the fabric component contains high-strength fiber Kevlar, its mechanical properties are higher, but the addition of high-strength fiber increases the difficulty of dyeing the fabric. In actual use, the fabric’s light fastness is reduced, and at the same time Increase the cost of the product and reduce the cost-effectiveness of the product. Although the mechanical prop...

Abstract

The invention discloses heat poof anti-flaming textile and its manufacturing method. It is blended by two anti-flaming fibers; one is aramid fiber 1313 fiber; the other is anti-flaming viscose fiber. Both of their content percentage are 20%-80%. Its special spinning technique demands are as follows: yarn count is 30s-70s / 2; yarn twist is 400-800T / M; twisting direction is í‹Sí

Description

Technical field [0001] The invention relates to a heat-resistant flame-retardant fabric and its production process. Background technique [0002] Flame-retardant fabrics have a wide range of uses, and their application areas have expanded from clothing fabrics to architectural interiors, aircraft, ships, and industrial fabrics, and they have attracted more and more attention. At present, the flame-retardant protective clothing industries that have been listed in the country are metallurgy, petroleum, chemical, forestry, fire protection and other industries. In addition, according to relevant national standards, flame-retardant protective clothing should be used in coal, transportation, machinery, weapons and other departments. In modern warfare, the army also needs a large number of flame-retardant combat clothing. [0003] The flame-retardant properties of textile materials are mainly obtained by two methods. One is to perform flame-retardant finishing of textile materials to ac...
