Problems solved by technology

[0003] At present, most of the fabrics or clothing used for the above purposes are cotton or cotton and other chemical fiber blended products that are flame-retardant finished, and there are defects such as cotton is easy to mold, poor strength, non-lasting flame-retardant effect, and poor heat resistance.
The use of flame-retardant polyester, nylon and other fibers will cause secondary damage due to the obvious droplet phenomenon.
Currently used fibers with high temperature resistance (such as aramid fibers, polyimide fibers and their modified fibers, polyazole fibers, carbon fiber pre-oxidized silk, etc.), can solve the problems of permanent flame retardancy and heat protection, but In terms of printing and dyeing properties (such as dyeing rate, dyeing color fastness, and dyeing brightness), there are difficulties in dyeing, inability to dye dark colors, low color fastness, low coloring rate, poor reproducibility, and high cost (glass The dyeing temperature is above 250°C and the dyeing temperature is high); in addition, the uncomfortable feeling of wearing the above-mentioned high-temperature-resistant fiber also hinders the batch application of the above-mentioned high-temperature-resistant fiber products in the above-mentioned fields
[0004] Blended polymer fibers containing aramid and polyarylsulfone have sulfone groups, although the glass transition temperature is higher than that of steel rod fibers, but sulfone groups are easy to color

Embodiment 1

[0158] The fiber weight ratio is: 30% blended polymer fibers of aromatic polyamide and polyarylsulfone, 20% flame-retardant nylon, 35% flame-retardant viscose, 15% aramid 1414, and the four fibers pass through conventional cotton spinning system equipment The prepared clear cotton blended sliver is then spun into 24s spun yarn by a ring spinning frame, and doubled by a ply machine to make a flame-retardant 24s / 2 ply yarn as a weaving warp yarn. Take the same similar process and blending ratio to make 20s / 2 as weaving weft yarn. The natural color twill fabric with a grammage of 267g / m2 is woven by an air jet machine. The washed fabric is jet dyed in an overflow dye vat. Gained colored finished fabric grammage is 282g / m .

Embodiment 2

[0160] The fiber weight ratio is: 25% blended polymer fibers of aromatic polyamide and polyarylsulfone, 30% flame-retardant nylon, 35% flame-retardant viscose, 10% aramid 1414, and the four fibers pass through conventional cotton spinning system equipment The prepared clear cotton blended sliver is then spun into 30s spun yarn by a compact spinning frame, and then doubled by a ply machine to make a flame-resistant 30s / 2 ply yarn as a weaving warp yarn. Take the same similar process and blending ratio to make 28s / 2 as weaving weft yarn. Weave into the natural color twill fabric of grammage 203g / m2 by shuttle loom. The washed fabric is jet dyed in an overflow dye vat. Gained colored finished fabric grammage is 210g / m2.

Embodiment 3

[0162] The fiber weight ratio is: 20% blended polymer fibers of aromatic polyamide and polyarylsulfone, 35% flame-retardant nylon, 40% flame-retardant viscose, 5% aramid 1414, and the four fibers pass through conventional cotton spinning system equipment The prepared clear cotton blended sliver is then spun into 32s spun yarn by a compact spinning frame, and then doubled by a ply machine to make a flame-retardant 32s / 2 ply yarn as a weaving warp yarn. Weave into the natural color plain weave fabric of grammage 201g / m2 by shuttle loom. The washed fabric is jet dyed in an overflow dye vat. Gained colored finished fabric grammage is 208g / m2.

Abstract

The present invention relates to a flame-resistant yarn comprising blended polymer fibers of aromatic polyamide and polyarylsulfone, fabrics and garments made therefrom, and methods for their preparation. The present invention relates to a kind of yarn, which comprises: high temperature resistant intrinsic flame retardant fiber (A); conventional flame retardant fiber (B), said conventional flame retardant fiber is selected from flame retardant nylon, flame retardant polyester, flame retardant acrylic; Burn cellulose fibers (C). The yarn of the invention is mainly used in the preparation of protective camouflage fabrics and clothing with good permanent flame retardancy, abrasion resistance and comfort.

Description

technical field [0001] The present invention relates to a flame-resistant yarn comprising blend polymer fibers of aromatic polyamide and polyarylsulfone, fabrics and garments made therefrom, and methods for their preparation. The yarn of the invention is mainly used in the preparation of protective camouflage fabrics and clothing with good permanent flame retardancy, abrasion resistance and comfort. Background technique [0002] Firefighters, emergency responders, racing personnel, military personnel, and industrial production personnel are often exposed to flames or high temperatures. The protective clothing or protective products they need must not only have high temperature resistance and permanent flame retardancy, but also have excellent Wear resistance, at the same time, due to the human body's strenuous exercise and high temperature occasions, the human body's perspiration is doubled, so the fabrics used in such occasions also need to have good comfort, moisture perme...
