Embodiment 1

[0028] First select 55 parts by weight of flax raw material and 45 parts by weight of tencel strips, divide the flax into pounds, and then pass through the large cut, the first dimension comb, the middle cut, the second dimension comb, the small cut, and the third Comb first, and then make linen slivers by rowing and stretching; the tencel slivers are incorporated into the linen slivers for sliver making, and blended rovings are prepared by drawing five times, and the rovings are passed through Squeeze to obtain spun yarn, then dry, wind and pack it into the required blended yarn.

[0029] Wherein described boiling comprises the steps:

[0030] (1) pickling: under the normal pressure that temperature is 30 ℃, in batching is: concentrated sulfuric acid (concentration is the sulfuric acid solution of 98%) 15kg, osmotic agent 5kg 10000 kilograms of aqueous solutions are processed, and the treatment time is 20min.

[0031] (2) Sub-bleaching: Under normal pressure at a temperature...

Abstract

The invention relates to a blended yarn of flax and Tencel fiber, wherein the flax is 50-60%; the Tencel fiber is 40-60%; and its preparation comprises: (1) preparing the flax into blended yarn bar to be mixed with Tencel fiber into bar, and combining the bars into thick yarn; (2) boiling said thick yarn into thin yarn; (3) drying the thin yarn and winding to prepare the blended yarn; and the boiling process in the step (2) comprises: washing with hydric sulphate solution; bleaching with the mixture of sodium chlorite and sodium nitrate; first washing with water; oxygen bleaching with the mixture of sodium carbonate, caustic soda, sodium silicate and hydrogen dioxide solution; second washing with water. The inventive blended yarn has the advantages of two fibers, and the boiling process can increase the spinning number of flax; therefore, the product has crinkle resistance and better brightness, etc.

Description

technical field [0001] The present invention mainly relates to a spinning yarn and its production process, in particular to the blended yarn of flax and tencel and its production process. Background technique [0002] Flax cellulose has the reputation of "fiber queen". Its textiles have the characteristics of moisture absorption, fast heat dissipation, strong tensile force, good gloss, fast moisture dissipation, acid and alkali resistance, and rot resistance, but its shortcomings are poor spinnability and wrinkle resistance. . [0003] Tencel fiber is a brand new fiber produced from wood pulp by solvent spinning. It has the "comfort" of cotton, the "strength" of polyester, the "luxurious beauty" of wool fabric and the "unique touch" and "soft drape" of silk. It is extremely tough no matter it is dry or wet. In the wet state, it is the first cellulose fiber with a wet strength far superior to that of cotton. 100% pure natural materials, coupled wit...
