Problems solved by technology

[0016] B. The fiber has low strength, which is the worst of the intrinsic flame-retardant fibers, and its strength is even slightly lower than that of cotton
As a result, the fabric has low tensile strength, is not wear-resistant, and is prone to pilling.

preparation example Construction

[0060] Based on the above-mentioned multifunctional intrinsically flame-retardant viscose blended yarn, the present invention also provides a preparation method. Described preparation method comprises the steps:

[0061] According to the percentage by weight, the flame-retardant viscose fiber, aramid fiber, and antistatic fiber are mixed, and the yarn is spun through a combination of manual and automatic configuration to obtain a single-ply yarn of 20-60s;

[0062] Two-fold twisting is performed on the obtained single-ply yarn of 20-60s to obtain double-ply multi-functional intrinsically flame-retardant viscose blended yarn of 20-60s.

[0063] Therefore, through two-for-one twisting, the multifunctional intrinsically flame-retardant viscose blended yarn of the present invention has the least damage, the least hairiness, and excellent strength performance.

[0064] Based on the above-mentioned multifunctional intrinsically flame-retardant viscose blended yarn, the present inve...

Embodiment 1

[0073] A viscose blended yarn comprising 50 wt% flame retardant viscose fiber and 50 wt% aramid was prepared. In the present embodiment, the mixed strip made is made into 25 strands, and the warp and weft yarns all use this yarn. Warp and weft yarns are used in 2 / 1 twill on rapier looms. The fabric structure is 75 warp yarns / inch*55 weft yarns / inch, and the basis weight is 250g / cm 2 . The fabric made as above is subjected to water setting finishing to obtain the final finished fabric.

Embodiment 2

[0075] A viscose blended yarn comprising 55 wt% flame retardant viscose fiber, 25 wt% meta-aramid, 18 wt% para-aramid and 2 wt% antistatic fiber was prepared. In the present embodiment, the mixed strip thus made is made into 40 strands, and the warp and weft yarns all use this yarn. Warp and weft yarns are used in 2 / 1 twill on rapier looms. The fabric structure is 90 warp yarns / inch*60 weft yarns / inch, and the basis weight is 180g / cm 2 . The fabric made as above is subjected to water setting finishing to obtain the final finished fabric.

Abstract

The invention provides multifunctional inherent-flame-retardant viscose blended yarn, fabric and a yarn preparation method. The viscose blended yarn comprises 50wt%-80wt% of flame-retardant viscose fibers, 20wt%-50wt% of aromatic polyamide fibers and 0-5wt% of antistatic fibers. The multifunctional inherent-flame-retardant viscose blended yarn has the multiple advantages of electric arc resistance, high temperature resistance, heat insulation, comfort, breathability and the like; the fabric is low in cost, high in cost performance and excellent in protective performance and has the performance of high fiber strength, tearing resistance, excellent wear resistance, good flame retardance, high-temperature resistance, heat insulation and the like. Therefore, the industrial enlarged production requirement is sufficiently met, and personal safety of a worker can be sufficiently guaranteed.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a viscose blended yarn and fabric with fire prevention, arc prevention, high temperature resistance, heat insulation and other multifunctional intrinsic flame retardancy, and a preparation method of the yarn. Background technique [0002] With the development of science and technology and the improvement of people's living standards, people pay more attention to safety and health, and have higher and higher requirements for safety protection products. Especially for employees engaged in manufacturing, construction, mining, electric power, gas and other industries, flame-retardant fabrics with single functions and protective equipment with low performance are gradually eliminated by people. In the upgrading of protective clothing, safety and protective textiles not only have high technology content, high added value and high efficiency, but also cater to the development trend of ...
