Problems solved by technology

[0002] Chitosan fiber does not contain processing agents and drugs that cause allergic reactions, high-purity 100% chitosan fiber (chitosan 100) has a high safety factor, has antibacterial and deodorizing properties, promotes wound healing, and has excellent cell regeneration effects and A new product with no toxic and side effects, the fiber is made into strips, which can be blended with other fibers into yarn to make woven and knitted products, but its fiber strength is poor, so it is not suitable for spinning alone, and it is usually drawn with cotton fibers. However, because the transfer between fibers in the drawing process cannot be accurately controlled, many chitin fibers are transferred to the inside of the yarn, which reduces the overall function of the yarn

preparation example Construction

[0022] The preparation method of the present invention is the following steps:

[0023] ①. The filament bundled multifilaments obtained by spinning carapaceous fibers, the number of monofilaments in the multifilaments is controlled between 150 according to the special number of single fibers, and the multifilaments are air-jet entangled to make the intertwining degree 80 pieces / m, stay in the stretching false twisting heater for 0.15 seconds, so that the temperature of the running single fiber yarn at the outlet of the heater is 80°C higher than its glass transition temperature, and stretching false twisting is carried out at the same time with a stretching ratio of 1.2 times Processing to make false twist, and then cut the false twist yarn into 35-55mm short fiber state;

[0024] ②. After cleaning, carding, drawing the obtained short fibers and noodles respectively into the friction spinning machine for spinning, wherein the cotton fibers are drafted by the rollers to supply ...

Embodiment 1

[0028] Ingredients: Shell fiber 45%, cotton fiber 55%;

[0029] Preparation:

[0030] ①. The filament bundled multifilaments obtained by spinning carapaceous fibers, the number of monofilaments in the multifilaments is controlled between 150 according to the special number of single fibers, and the multifilaments are air-jet entangled to make the intertwining degree 80 pieces / m, stay in the stretching false twisting heater for 0.15 seconds, so that the temperature of the running single fiber yarn at the outlet of the heater is 80°C higher than its glass transition temperature, and stretching false twisting is carried out at the same time with a stretching ratio of 1.2 times Processing to make false twist, and then cut the false twist yarn into 35-55mm short fiber state;

[0031] ②. After cleaning, carding, drawing the obtained short fibers and noodles respectively into the friction spinning machine for spinning, wherein the cotton fibers are drafted by the rollers to supply t...

Embodiment 2

[0034] Ingredients: 50% of chitosan fibers, 50% of cotton fibers, and its preparation method is the same as that of Example 1.

[0035] In summary, the natural chitin fiber and cotton fiber blended functional fabric of the present invention is made of chitin fiber and cotton fiber as raw materials, the chitin fiber is spun, the multifilament is air-jet entangled, stretched, false twisted, Heating, the transfer between fibers in the drawing process can be accurately controlled, improving the function of the yarn and the production value of the product.

Abstract

The invention provides a combination of functional fabrics of natural chitin fiber and cotton fiber blending and process for parathion, wherein chitin fiber and cotton fiber are used as raw materials, the chitin fiber is spun, multifilament is jetted, entangled, stretched, false-twisted and heated, the metastasis between the fibers is capable of being accurately controlled in the state of drawing, and the function of yarn and the production value of a product are improved.

Description

technical field [0001] The invention relates to a combination of functional fabrics and a preparation method thereof, in particular to functional fabrics blended with natural chitin fibers and cotton fibers. Background technique [0002] Chitosan fiber does not contain processing agents and drugs that cause allergic reactions, high-purity 100% chitosan fiber (chitosan 100) has a high safety factor, has antibacterial and deodorizing properties, promotes wound healing, and has excellent cell regeneration effects and A new product with no toxic and side effects, the fiber is made into strips, which can be blended with other fibers into yarn to make woven and knitted products, but its fiber strength is poor, so it is not suitable for spinning alone, and it is usually drawn with cotton fibers. Blending is carried out, but because the transfer between fibers in the drawing process cannot be accurately controlled, many chitin fibers are transferred to the inside of the yarn, reduci...
