Problems solved by technology

Flax fiber contains a lot of miscellaneous, high rigidity, brittle and hard, easy to damage, and has a lot of short fibers, so the falling rate in the cleaning process is relatively high, while the tencel fiber is relatively small, so it is difficult to determine the optimal combination of the two. It is also difficult to master the process conditions of opening and carding
In addition, it is easy to produce unevenness in drawing frame and roving process

Embodiment Construction

[0028] raw material:

[0029] The dry strength of flax fiber is 3.3-4.0cN / dtex, the wet strength is 3.5-5.2cN / dtex, and the main body length is 17-20mm.

[0030] Tencel fiber fineness is 1.0~1.8dtex, main body length is 35~40mm.

[0031] Process flow:

[0032] 1. Raw material preparation process: The moisture regain of flax fiber and tencel fiber is basically maintained at about 13%, so these two raw materials should be regained. The specific method and time of moisture regain are as follows:

[0033] flax fiber

72 hours

spray water mist

tencel fiber

48 hours

spray water mist

[0034] After regaining moisture, it is necessary to test and calculate the moisture regain of the two raw materials to determine the appropriate blending ratio, which is generally 35%-40% for flax fiber and 60%-65% for tencel fiber.

[0035] 2. Opening and cleaning process: the distance between the cotton equalizing roller and the corner nail curtain is 30mm, th...

Abstract

The invention provides a flax fiber and tencel fiber blended yarn and a preparation method thereof. The flax fiber and tencel fiber blended yarn comprises 35 to 40 weight percent of flax fiber and 60 to 65 weight percent of tencel fiber, wherein the twist degree of the blended yarn is 21.32 to 23 T / inch; the average strength of the blended yarn is 300 g; and the elongation percentage of the blended yarn is 14.1 percent. The flax fiber and tencel fiber blended yarn combines moisture absorption, perspiration, antibacterial effect and the like of the flax fiber and the healthy environmentally-friendly characteristic of the tencel fiber, has the advantages of natural environmental friendliness, cooling performance and antibacterium, and can be applied to clothing fabrics and other industries.

Description

technical field [0001] The invention relates to a blended yarn and a preparation method thereof, in particular to a blended yarn of flax fiber and tencel fiber, and a production process of the blended yarn. Background technique [0002] Tencel fiber has the excellent characteristics of cellulose fiber, its dry breaking strength is close to polyester, better than viscose fiber, and combines the advantages of natural fiber and synthetic fiber; flax fiber is the only bundle fiber in natural textile fibers, which has moisture absorption and heat dissipation. Fast, eliminate static electricity, breathable and smooth and so on. [0003] The physical properties of flax and tencel fibers are too different, making blending very difficult. Flax fiber contains a lot of miscellaneous, high rigidity, brittle and hard, easy to damage, and has a lot of short fibers, so the falling rate in the cleaning process is relatively high, while the tencel fiber is relatively small, so it is difficu...
