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% of the blended polymer fiber of aromatic polyamide and polyarylsulfone, 20% of flame-retardant nylon, 35% of flame-retardant viscose, 15% of aramid 1414, four kinds of fibers are passed through conventional cotton spinning system equipment The prepared clear cotton blended sliver is then spun into a 24s spun yarn by a ring spinning frame, and then plied by a plying machine to make a flame-retardant 24s / 2 ply yarn as a weaving warp. Using the same similar process and blending ratio, 20s / 2 is used as weaving weft yarn. The natural color twill fabric with a weight of 267g / m2 is produced by air-jet weaving. The washed fabric is spray dyed in the overflow dyeing vat. The resulting colored finished fabric has a gram weight of 282g / m2.

Embodiment 2

[0160] The fiber weight ratio is: 25% of the blended polymer fiber of aromatic polyamide and polyarylsulfone, 30% of flame-retardant nylon, 35% of flame-retardant viscose, 10% of aramid 1414, the four types of fibers are passed through conventional cotton spinning system equipment The prepared clear cotton blended sliver is then spun into a 30s spun yarn by a compact spinning frame, and then twisted by a twisting machine to make a flame-retardant 30s / 2 ply yarn as a weaving warp. Using the same similar process and blending ratio to make 28s / 2 as weaving weft yarn. A natural twill fabric with a weight of 203g / m2 is produced through a shuttle loom. The washed fabric is spray dyed in the overflow dyeing vat. The resulting colored finished fabric has a weight of 210g / m2.

Embodiment 3

[0162] The fiber weight ratio is: 20% of the blended polymer fiber of aromatic polyamide and polyarylsulfone, 35% of flame-retardant nylon, 40% of flame-retardant viscose, 5% of aramid 1414, the four types of fibers pass through conventional cotton spinning system equipment The prepared clear cotton blended sliver is then spun into a 32s spun yarn by a compact spinning frame, and then plied by a twister to make a flame-retardant 32s / 2 ply yarn as a weaving warp. A plain weave fabric with a basic color of 201g / m2 is produced by weaving a shuttle loom. The washed fabric is spray dyed in the overflow dyeing vat. The resulting colored finished fabric has a weight of 208g / m2.

Abstract

The invention relates to a fire-retardant yarn of a blended polymer fiber containing aromatic polyamide and polyarylsulfone and fabric and clothes produced by the fire-retardant yarn and production method of the fabric and clothes. The yarn comprises a high temperature resistant nature fire-retardant fiber (A), a conventional fire-retardant fiber (B) and a fire-retardant cellulose fiber (C), and the conventional fire-retardant fiber is selected from fire-retardant polyamide, fire-retardant polyester and fire-retardant acrylic. The yarn is mainly used for producing protective camouflage fabric and clothes which are forever fire retardant, wear resistant and good in comfortableness.

Description

Technical field [0001] The present invention relates to a flame-retardant yarn containing a blended polymer fiber of aromatic polyamide and polyarylsulfone, fabrics and garments prepared therefrom, and their preparation method. The yarn of the present invention is mainly used to prepare protective camouflage fabrics and clothing with permanent flame-retardant, abrasion resistance and good comfort performance. Background technique [0002] Firefighters, emergency responders, racing personnel, military personnel, and industrial production personnel are often exposed to flames or high temperatures. In addition to high temperature resistance and permanent flame retardant properties, the protective clothing or protective products they need need to have excellent Wear resistance. At the same time, the human body’s perspiration is doubled due to intense human exercise and high-temperature occasions. Therefore, the fabric used for this occasion also needs to have good comfort, moisture p...
