Abstract
A flat visose fibre is disclosed, which is prepared through one-step coagulating bath at 45-55 deg.C. The said bath is prepared from sulfuric acid, sodium sulfate and zinc sulfate. The resultant flat viscose fibre has fineness of 333.3 dtex 666.7 dtex, dry crack strength of 1.55-1.64 CN/dtex, wet breaking strength of 0.69-0.77 Cn/dtex, dry elongation of break of 18-23% and dyeing index not less than 3.5. Its advantages include simple process and high output and quality.
Description
The present invention relates to a kind of artificial silk and manufacture method thereof in the spinning industry, definitely say so a kind of flat viscose fibre and manufacture method thereof.
Along with improving constantly of people's living standard, the dress ornament of pursuing stylization has become a kind of fashion, and the viscose glue flat filament is an optimum feed stock of making stylized fabric, and it is fit to do knit fabric and woven fabric, have the style of hair, flax fibre, comfortable and easy to wear, well-pressed.The existing abroad commodity listing of this product, but price is more expensive, can not satisfy the demand in market, domestic still do not have producer's Development and Production.The external flat filament system that produces adopts two-bath process, technology more complicated.
The objective of the invention is to: it by one-step coagulating bath flat viscose fibre and manufacture method thereof are provided.
The objective of the invention is to realize by the enforcement following technical proposals: the manufacturing technique of it by one-step coagulating bath flat viscose fibre is as follows: (1) is flooded the cotton pulp dregs of rice through alkali lye, carry out sulfonating reaction after experienced and make viscose glue, more after filtration, adopt for spinning after the maturation, deaeration; (2) with above-mentioned spinning viscose glue by being immersed in the special flat shower nozzle spray collodion silk in the acid tank and carrying out disposable coagulating bath, the body lotion of coagulating bath is the sulfuric acid of (105-135) g/L by concentration, concentration is the sodium sulphate of (220-300) g/L, concentration is that the solution of zinc sulfate of (10-40) g/L is formed, and the temperature of coagulation bath is 45-55 ℃; (3) above-mentioned fiber is again through peracid treatment, desulfurization, washing, pickling, make flat viscose fibre after washing, oil, dewater, drying.The flat viscose fibre of making, the fiber number of its fiber are 333.3dtex, 666.7dtex, its dry and cracked intensity is (1.55-1.64) CN/dtex, wet breaking strength is (0.69-0.77) CN/dtex, and dried elongation at break is (18-23) %, and dyeing shelves number average is more than 3.5.In sum, it by one-step coagulating bath flat viscose fibre and manufacture method thereof, include: having fiber number is 333.3dtex, 666.7dtex, its dried fracture strength is (1.55-1.64) CN/dtex, wet breaking strength is (0.69-0.77) CN/dtex,. dried elongation at break is (18-23) %, dyeing shelves number at the flat viscose fibre product of all performance characteristics more than 3.5 and the feature that produces disposable this method of coagulating bath method of this kind product is: the coagulation bath that flat collodion silk passed through that the shower nozzle spray goes out, by concentration is the sulfuric acid of (105-135) g/L, concentration is the sodium sulphate of (220-300) g/L, concentration is that the solution of zinc sulfate of (10-40) g/L is formed, and the temperature of body lotion is (45-55) ℃.
The invention has the advantages that: adopt it by one-step coagulating bath to produce flat viscose fibre, have outstanding advantages such as technological process is short, product quality is high, cost is lower.Comfortable and easy to wear, well-pressed with this production lining, can constantly satisfy the demand of domestic and international market.
