Problems solved by technology

[0005] The disadvantage of the prior art is that, in today's environment-friendly environment, the use of a large amount of acid and alkali chemical reagents will not only destroy the ecological environment, but also be harmful to the health of the human body after remaining on the fiber.
The disadvantage of this invention is that strong alkali reagents such as sodium hydroxide are used, which is not environmentally friendly and unfavorable to human health

Embodiment 1

[0034] A pretreatment method for ring spinning cotton and linen blended yarn, comprising the steps of:

[0035] (A), the extraction of flax:

[0036] The formula of ecological emulsifier is: 2wt% cottonseed oil, 2wt% rapeseed oil, 3.5wt% pectinase, 2.5wt% sodium dodecylbenzenesulfonate, 1.5wt% salt, 88.5wt% water.

[0037] The second coarse flax is loosely packaged, classified according to the color depth and the light and shade of the second coarse flax, and the bag is stacked. When stacking, an ecological emulsifier with a weight of 18wt% of the second coarse flax is evenly sprayed, and the second coarse flax is controlled. The coarse compacted density is consistent, and then the sacking treatment is carried out for 84 hours; the flax after the sacking is subjected to strong opening through the continuous three licker-in carding machine to obtain rough flax, and the three licker-in carding machine The licker-in speed is 850r / min; the crude flax is subjected to secondary suf...

Embodiment 2

[0044] A pretreatment method for ring spinning cotton and linen blended yarn, comprising the steps of:

[0045] (A), the extraction of flax:

[0046] The formula of ecological emulsifier is: 2.5 wt% peanut oil, 1.5 wt% soybean oil, 5wt% pectinase, 2 wt% sodium dodecylbenzene sulfonate, 2 wt% salt, 87 wt% water.

[0047] The second coarse flax is loosely packaged, classified according to the color depth and the light and shade of the second coarse flax, and the bag is stacked. When stacking, an ecological emulsifier with a weight of 20wt% of the second coarse flax is evenly sprayed, and the second coarse flax is controlled. The coarse compacted density is consistent, and then the sacking treatment is carried out for 48 hours; the flax after the sacking is subjected to strong opening through the continuous three licker-in carding machine to obtain rough flax, and the three licker-in carding machine The licker-in speed is 900r / min; the crude flax is subjected to secondary suffoc...

Embodiment 3

[0054] A pretreatment method for ring spinning cotton and linen blended yarn, comprising the steps of:

[0055] (A), the extraction of flax:

[0056] The formula of ecological emulsifier is: 1 wt% cottonseed oil, 2 wt% soybean oil, 2 wt% pectinase, 2 wt% sodium dodecylbenzene sulfonate, 1 wt% salt, 92 wt% water.

[0057] The second coarse flax is loosely packaged, classified according to the color depth and the light and shade of the second coarse flax, and the bag is stacked. When stacking, an ecological emulsifier with a weight of 15wt% of the second coarse flax is evenly sprayed, and the second coarse flax is controlled. The coarse compacted density is consistent, and then subjected to simmering treatment for 120 hours; the second rough flax after suffocation is subjected to strong opening through a continuous three licker-in carding machine to obtain rough flax, and the three licker-in carding machine The licker-in speed is 800r / min; the crude flax is subjected to seconda...

Abstract

The present invention relates to the technical field of textile pretreatment of textile fiber, and discloses a ring spun flax-cotton blended yarn pretreatment method including: (A), flax velvet extraction, to be more specific, flax scutching tow is stuffed in a warehouse, and sprayed with an ecological emulsifier; the flax scutching tow stuffed in the warehouse is strongly opened; crude flax velvet is secondarily stuffed in the warehouse; the crude flax velvet secondarily stuffed in the warehouse is finely carded; the fine flax velvet is thirdly stuffed in the warehouse; wherein the ecological emulsifier formulation includes vegetable fat, pectinase, a surfactant, salt and water; (B), cotton and flax card sliver preparation, to be more specific, the fine flax velvet which is thirdly stuffed in the warehouse is prepared into a flax velvet card sliver; and natural colored cotton and ecological fine staple cotton are mixed to prepare a cotton card sliver; and (C), flax-cotton blended yarn preparation, to be more specific, the flax velvet card sliver and the cotton card sliver are bonded to prepare a drawn sliver, and the drawn sliver is spun to obtain a flax-cotton blended yarn. The flax-cotton blended yarn uses the new ecological emulsifier, and is green, and environmentally friendly; the obtained product is small in impurity content, permeable and good in hand feel.

Description

technical field [0001] The invention relates to the technical field of textile fiber pre-processing technology, in particular to a pre-processing method of ring spinning cotton and linen blended yarn. Background technique [0002] In today's world, the enthusiasm of human beings to pursue green and ecological environmental protection continues to rise. In the production of traditional textiles, a large number of chemical products such as sizing materials, bleaching dyes, and finishing agents are used, which cause serious pollution to the environment and bring hidden dangers to human health. Therefore, green and eco-friendly textiles have become a high-level pursuit of consumers. [0003] Hemp fiber has good moisture absorption and air permeability, low static electricity and antibacterial properties, but its elasticity and wear resistance are poor, so it usually needs to be blended with other fibers to make fabrics. Flax is one of the main hemp fibers. The surface of flax h...
