Embodiment 1

[0048] Match the pre-spinning injection system with the improved viscose fiber production line with a daily output of 25 tons of pearl particles. The metering pump for the viscose collagen solution uses a 14,000 liter / hour NEMO single-screw pump, the pearl particle slurry uses a 1,000 liter / hour diaphragm metering pump, the primary mixer uses a 24,000L / h static mixer, and the secondary mixer uses a 24,000L / h rotor / stator high shear mixer, the fiber production capacity of the corresponding spinning machine is 25 tons / day.

Embodiment 2

[0050] To prepare reinforced viscose fiber containing pearl particles, the content of methylcellulose in the raw material pulp is not less than 93%.

[0051] Viscose collagen composition: cellulose 9.0%, NaOH 5.6%, CS 2 (p-methylcellulose) 33%, denaturant A 0.5%, maturity 10ml (10% ammonium chloride), falling ball viscosity 50sec.

[0052] The composition of the pearl particle slurry: the pearl particle content is 20wt%, the dispersant is 5wt%, the rest is water, and the pearl particle is less than 1 μm.

[0053] The pre-spinning injection system of Example 1 was used to adjust the flow rate of the stock solution and the slurry metering pump to ensure that the proportion of pearl particles in the fiber was 4.5 wt%, and the above-mentioned blended stock solution was subjected to viscose wet spinning and post-treatment.

[0054] Spinning bath composition: sulfuric acid 120g / l, zinc sulfate 17g / l, sodium sulfate 320g / l, additive D 0.05g / l, immersion length 40cm, bath temperature...

Abstract

The invention relates to improved viscose fiber containing pearl particles and a manufacturing method thereof. The fiber is reinforced, high-wet-modulus or rich and strong viscose fiber, the total amount of the fiber comprises 0.1 to 15.0 weight percents of the pearl particles, 0.2 to 6.0 weight percent of denaturant, and 79.0 to 99.7 weight percents of cellulose, the dry rupture strength of the fiber is more than or equal to 2.2 cN/dtex, and the wet rupture strength of the fiber is more than or equal to 1.2 cN/dtex. The mixture of one or more components selected from the copolymer of fatty amines, polyamines compounds, alcohol amine, polyoxyethylene and the aliphatic amine thereof, fatty acid, fatty alcohol, amide condensation compounds, ethylene oxide and propylene oxide, quaternary ammonium, pyrrolidine dithiocarbamate, dithioglycol, imidazole and derivatives thereof, is adopted as the denaturant. The manufacturing method for the fiber comprises the steps of: (1) the preparation of a viscose stock solution; (2) the preparation of slurry of the pearl particles; (3) the injection mixing of the slurry of the pearl particles and the viscose stock solution through a pre-spinning injection system; (4) spinning; and (5) post-treatment.

Description

technical field [0001] The invention relates to the technical fields of chemical engineering, viscose fiber manufacturing process, polymer blending modification and the like, in particular to an improved viscose fiber containing pearl particles and a manufacturing method thereof. Background technique [0002] After decades of development, viscose fiber has become a chemical fiber with mature production technology and widely used. And formed a series of viscose fiber products from low to high strength, including ordinary type, enhanced type, semi-high wet modulus type, high wet modulus type and rich strength type. The wet modulus of the latter three varieties has also increased. Meets or exceeds cotton fiber levels. Its basic technology is based on the synthesis and decomposition of cellulose xanthate, but due to different varieties, there are some differences in the selection of pulp raw materials and manufacturing processes, resulting in fiber properties, especially streng...
