Embodiment 1-3

[0026] Embodiment 1-3: a kind of high-strength composite fiber, described high-strength viscose fiber is obtained by following process method, process method this comprises the following steps:

[0027] Step 1, vaporize aromatic diamine and aromatic diacid chloride, in gaseous NH 3 Mixing under low temperature, and then carry out gas-phase polycondensation reaction in a tubular reactor to prepare aromatic polyamide, the reaction temperature condition is 200-300°C;

[0028] Step 2. Mix the cooled aromatic polyamide and viscose collagen solution uniformly at a mass ratio of 1:20 at 90-150°C for 30 minutes to obtain a mixed solution. The viscose collagen solution contains cellulose yellow Sodium hydroxide solution of sodium orthoate;

[0029] Step 3, filtering the mixed solution through a filter to remove larger particles or impurities;

[0030] Step 4, adding high-carbon alcohol as a defoamer to the mixed solution of step 3, in order to remove the foam in the mixed solution; ...

Abstract

The invention discloses high tenacity viscose fiber. A processing method of the high tenacity viscose fiber comprises the following steps of: vaporizing aromatic diamine and aromatic oxalyl chloride, and mixing under gaseous state NH3; uniformly mixing aromatic polyamide and viscose solution at the temperature of 90-150 DEG C according to mass ration of 1:20 to obtain mixed liquor, wherein the viscose solution is sodium hydroxide solution containing cellulose sodium xanthogenate; filtering larger particles or / and impurities of the mixed liquor through a filter; adding defoamer into the mixed liquor, and removing foam in the mixed liquor; after extruding the mixed liquor through a spinneret orifice to form mixed liquor trickle, coagulating the mixed liquor trickle into nascent fiber through coagulating bath at the temperature of 60-80 DEG C; and drafting the nascent fiber to form composite fiber filament. According to the high tenacity viscose fiber, the technical problem that the existing viscose fiber strength is low is solved, and the strength property of the viscose fiber is greatly improved.

Description

technical field [0001] The invention relates to a high-strength viscose fiber, which belongs to the technical field of textile fabrics. . Background technique [0002] Viscose fiber is the full name of viscose fiber. Viscose fiber is a cellulose fiber produced from cotton or other natural fibers. The moisture content of viscose fiber meets the physiological requirements of human skin, and it has the characteristics of smooth and cool, breathable, antistatic, and brilliant dyeing. [0003] Viscose fiber is a regenerated cellulose fiber. It is made of natural cellulose as raw material, which is made into soluble cellulose sulfonate through alkalization, aging, sulfonation and other processes, and then dissolved in dilute lye to make viscose, which is made by wet spinning. Viscose fiber has good hygroscopicity, and the moisture regain is about 13% under general atmospheric conditions. After absorbing moisture, it swells significantly, and the diameter increases by up to 50...
