Abstract
The present invention relates to flat viscose silk which is a fashion product in the current market. Flat viscose silk products come into the abroad market and have no factories to develop and produce in China. The present invention aims to develop the flat viscose silk product and a preparation method thereof so as to satisfy market requirements. The present invention is characterized in that the flat viscose silk is developed and has the performances that the fineness is 667 tax, 1220 tax, 2220 tax and 4440 tax; the dry breaking strength is from 0.85 to 1.50 CN/tax, the wet breaking strength is from 0.4 to 0.8 CN/tax, the dry breaking elongation rate is from 10 to 23 %, and the dye index is not less than 2.5. The preparation method of the flat viscose silk is characterized in that the flat viscose silk strip is only processed through once coagulation bath, the bath liquid is composed of 140 to 170 g/l of sulfuric acid, 250 to 300 g/l of sodium sulphate and 10 to 40 g/l of zinc sulphate, and the temperature of the bath liquid is from 45 to 55 DEG C. The flat viscose silk of the present invention has the prominent advantages of short process flow, high output and quality, low cost, etc., and can satisfy the heavy requirement of a market.
Description
The present invention relates to a kind of artificial silk and preparation method thereof in the spinning industry, a kind of flat viscose fibre and preparation method thereof of definitely saying so.
Along with improving constantly of people's living standard, the dress ornament of pursuing stylization has become our 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 preparation method are provided.
The purpose of this method realizes by implementing following technical proposals: the preparation technology 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 special flat shower nozzle with 50-90 rice/minute spinning speed ejection collodion silk, and in acid bath, carry out disposable solidifying, the body lotion of coagulating bath is the sulfuric acid of (140-170) g/l by concentration, concentration is the sodium sulphate of (250-300) g/l, concentration is that the solution of zinc sulfate of (10-40g/l) is formed, and the temperature of coagulation bath is 45-55 ℃; (3) above-mentioned fiber is again through washing, bleaching (chlorine floats, hydrogen float), pickling, washing, neutralization, make flat viscose fibre after washing, oil, dewater, drying.The flat viscose fibre of making, the fiber number of its fiber are 1220dtex, 2220dtex, 4440dtex, its dried fracture strength is (0.85-1.50) CN/dtex, wet breaking strength is (0.40-0.80) CN/dtex, and dried elongation at break is (10-23) %, and dyeing shelves number average is more than 2.5.
In sum, it by one-step coagulating bath flat viscose fibre and preparation method thereof, include: having fiber number is 1220dtex, 2220dtex, 4440dtex, its dried fracture strength is (0.85-1.50) CN/dtex, wet breaking strength is (0.40-0.80) CN/dtex, dried elongation at break is (10-23) %, and dyeing shelves number is at the flat viscose fibre product of all performance characteristics more than 2.5 and produce the disposable coagulating bath preparation method of this kind product.The feature of this method is: the coagulation bath that flat collodion silk passed through that the shower nozzle spray goes out, is the sodium sulphate of 250-300g/l by concentration for sulfuric acid, the concentration of (the same coagulation bath composition) 140-170g/l, concentration is that the solution of zinc sulfate of 10-40g/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.
