Technical Field

The invention relates to the technical field of textile production, in particular to a yarn-dyed process of linen fabric.

Background

With the continuous improvement of the living standard of people, the pure hemp fabric becomes a main product for high-end consumption.

Although the linen yarn has better strength and can bear the non-sizing weaving, the abrasion resistance of the linen fiber is not good because the linen fiber lacks the natural crimping property and the fibers are not easy to cohere; secondly, the elastic property of the linen yarn is very poor, so that the yarn velvet is tense in the weaving process and is obviously easier to rub. Therefore, the prior art mostly adopts roving count flax cotton and pure flax yarn for production, such as 17 counts and 14 counts. However, the thick and thin warps are strongly rubbed by the reed during weaving, so that the strength of the warps is rapidly reduced, and the broken warp phenomenon is serious. And the linen yarn has long stabbing velvet, so that the problem of unclear opening is easily caused in the weaving process, and the improvement of the weaving efficiency is seriously influenced.

Disclosure of Invention

The invention aims to provide a weaving method of yarn-dyed pure flax fabric, which can improve the production efficiency and the production quality of pure flax.

The technical scheme of the invention is as follows: during weaving, 3 and 4 of the heald frames are empty healds; the dropper is used in the No. 1, No. 2, No. 5, No. 6, No. 3, No. 4; the tension of the warp yarns is 1.4 KN; the opening amount is 30 °.

In the heald frames, 3 and 4 are empty healds, the No. 1, 2, 5 and 6 are used as the warp stop sheets, and the No. 3 and 4 are empty, so that the broken warp phenomenon caused by excessive friction of the linen yarns can be greatly reduced.

The warp adopts 1.4KN of low tension, reduces the phenomenon that flax warp breaks under the condition that does not influence normal production.

By adjusting the opening angle to be 30 °, warp breakage caused by unclear opening angle due to such burr length of flax can be reduced.

Therefore, the invention mainly reduces the broken warp frequency to ensure that the weaving efficiency of the weaving machine is improved and the production quality of the pure flax fabric is ensured from the drafting method and the adjustment of the tension and the opening amount.

In general, the temperature in the weaving workshop is 25 ℃ and the humidity is 60%. The invention preferably adopts the high-temperature and high-humidity conditions with the temperature of 26 ℃ and the humidity of 82 percent, and can greatly reduce the problem of strength reduction of the linen yarns.

Detailed Description

Firstly, producing pure flax woven fabric, and meeting the requirements of tissue, warp and weft density and the like:

warp yarn: 21S pure linen yarn;

weft yarn: 21S pure linen yarn;

warp density: 64 pieces/inch;

weft density: 51 pieces/inch;

organizing: 1/1.

Secondly, drafting requirements of the warp yarns:

drafting: 1. 2, 5 and 6, and the heald frames 3 and 4 are empty frames.

Thirdly, weaving process:

1. the equipment model is as follows: the bitonal OPTIMAX high-speed rapier is disclosed.

2. The weaving environment requirement is as follows:

the temperature was 26 ℃ and the humidity was 82%. The problem of strength reduction of the linen yarns is solved by adopting a high-temperature and high-humidity environment.

3. Weaving technological parameters are as follows:

warp tension: 1.4 KN; by adopting the small tension, the phenomenon of the stretch breaking of the flax warp yarns is reduced under the condition of not influencing normal production.

Leveling time: 315 degrees;

a rear beam: +4/4 cm;

the drop wire adopts the threading methods of No. 1, No. 2, No. 5, No. 6, No. 3 and No. 4, so that the broken warp phenomenon caused by excessive friction of the linen yarns is reduced.

A warp stop frame: -1/15 cm;

height of the heald frame: conventionally, as follows: 113. 112, 109, 108;

opening amount: 30 degrees. The opening angle is enlarged, and the situation of warp breakage caused by unclear opening angle due to the long burrs of flax is reduced.

Fourthly, obtaining a result:

compared with the prior art, the warp and weft stop times are respectively reduced to 15 times/shift and 20 times/shift, the speed of the vehicle is improved to 380-400 rpm, the efficiency is obviously improved, and the efficiency can be improved to 90% from 60%.

The technical innovation of the invention is that the weaving of the yarn-dyed pure flax fabric with high efficiency and high quality is realized under the guarantee of the quality of the cloth cover by only integrating the existing equipment with little change and little leather and operation process resources without upgrading and updating the equipment.
