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] Aromatic polymer fibers containing sulfone groups have sulfone groups. Although the glass transition temperature is higher than that of steel rod fibers, sulfone groups are easy to color

Embodiment 1

[0170] The fiber weight ratio is: 30% H-PSA fiber, 20% flame-retardant nylon, 35% flame-retardant viscose, 15% aramid 1414, the four kinds of fibers pass through the clear cotton blended strip prepared by conventional cotton spinning system equipment, and then pass through the ring Spinning spinning machine spins into 24s spun yarn, which is made into flame-retardant 24s / 2 ply yarns as weaving warp yarns. 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

[0172] The fiber weight ratio is: 25% H-PSA fiber, 30% flame-retardant nylon, 35% flame-retardant viscose, 10% aramid 1414, the four kinds of fibers are passed through the clear cotton blended strip prepared by conventional cotton spinning system equipment, and then passed through compact The spinning frame spun into 30s spun yarn, which is combined by the plying machine to make a flame-retardant 30s / 2 ply yarn as the 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 207g / 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 gram weight of 212 g / m2.

Embodiment 3

[0174] The fiber weight ratio is: 20% H-PSA fiber, 35% flame-retardant nylon, 40% flame-retardant viscose, 5% aramid 1414, the four kinds of fibers pass through the clear cotton blended strip prepared by conventional cotton spinning system equipment, and then pass through compact The spinning frame spun into 32s spun yarn, which is combined with the yarn by the plying machine to make a flame-retardant 32s / 2 ply yarn as the weaving warp yarn. The plain weave fabric of 195g / 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 202g / m2.

Abstract

The invention relates to a flame retardant yarn comprising aromatic polymer fiber containing sulfuryl, a fabric and garment made of the same and a preparation method thereof. The yarn comprises a high temperature resistant inherent flame retardant fiber (A), conventional fire-retardant fiber (B) and flame retardant cellulose fiber (C). The conventional fire-retardant fiber (B) can be one of flame retardant nylon, flame retardant polyester and flame retardant acrylic selectively. The yarn is mainly applied to preparation of the protective camouflage fabric and garment with permanent flame retardance, wear resistance and good comfortable performance.

Description

Technical field [0001] The invention relates to a flame-retardant yarn containing aromatic polymer fibers containing sulfone groups, fabrics and garments prepared therefrom, and their preparation methods. 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 permeability, air permea...
