Problems solved by technology

[0003] However, the high volume specific resistance and initial modulus, low friction coefficient and crimp stability of polysulfone fibers are unfavorable to the processing of fibers such as spinning, weaving and dyeing.
The main problems in the spinning process are: small cohesion between fibers, difficult yarn formation, relatively low yarn strength, particularly prominent yarn hairiness, and many long hairs, which affect yarn quality

Embodiment 1

[0027] Weigh 30 kg of N,N'-bis(diphenoxythiophosphoryl)dithiooxalamide; 30 kg of N-hydroxymethyl-3-(dimethoxyphosphono)propionamide; three ( 2,3-dibromopropyl) 40 kilograms of isocyanurates, stir and mix uniformly and make composite flame retardant.

[0028] The above-mentioned composite flame retardant is mixed with the viscose solution, and shaped according to the conventional wet spinning and spinning process to obtain the flame-retardant viscose fiber, and the length of the flame-retardant viscose fiber is 38 mm. Wherein, the content of flame retardant in the finished product flame retardant viscose fiber is controlled to be 10wt%.

[0029] For the viscose solution in the raw materials, the weight percent content of methyl cellulose is 8.5%, the weight percent content of sodium hydroxide is 5%, the falling ball viscosity is 50 seconds, and the maturity is 12%.

[0030] Aramid sulfone fiber (provided by Shanghai Teanlun Fiber Co., Ltd. The mass ratio of aramid sulfone fi...

Embodiment 2

[0034] The preparation method is basically the same as in Example 1, except that the flame retardant used is N,N'-bis(diphenoxyphosphorylthio)dithiooxalamide instead of a composite flame retardant.

Embodiment 3

[0036] The preparation method is basically the same as in Example 1, except that the flame retardant used is N-methylol-3-(dimethoxyphosphono)propionamide instead of a composite flame retardant.

Abstract

The invention discloses a blended fabric of polysulfonamide and viscose fiber. The blended fabric of polysulfonamide and viscose fiber is formed by blending and weaving 40wt% to 80wt% of polysulfonamide and 20wt% to 60wt% of viscose fiber. The blended fabric of polysulfonamide and viscose fiber has the advantages that the afterflame time, the smoldering time and the damaged length meet the state standards, and the specified flame retardant requirement is met.

Description

technical field [0001] The invention relates to a fabric, in particular to a blended fabric of sulfonamide and viscose fiber. Background technique [0002] Polysulfone fiber, also known as polysulfone amide fiber, PSA fiber for short, trade name TANLON (TANLON). Aramid sulfone fiber is a kind of aromatic polyamide fiber with special structure. Its scientific name is polyphenylsulfone terephthalamide fiber. It is made from the condensation polymer of diphenyl sulfone and terephthaloyl chloride. The p-phenylene structure and sulfone group are introduced into the polysulfone fiber during production, so that the amide group and the sulfone group are connected to each other with a para-phenyl group and a meta-position group to form a linear macromolecule. Due to the presence of a strong electron-withdrawing sulfone group -(SO2)- on the main chain of the macromolecule, the electron cloud density of the nitrogen atom on the amide group is significantly increased through the conju...
