Problems solved by technology

[0002] The surface state of chemical synthetic fibers is generally smooth and smooth, with mirror luster and waxy feeling. When this fiber is used as a special fabric or application, it cannot achieve the desired effect. Generally, it is added to the melt-spun composite A variety of inorganic substances, such as silicon dioxide, titanium oxide, etc. (that is, matting), are effective for matting synthetic fibers, but have an impact on the color of the fibers. Excessive addition of matting agents will affect the mechanical properties of the fibers. The surface of the fiber is subjected to glow discharge plasma radiation to make the fiber have an uneven surface, but the cost is too high and the practicability is not strong

preparation example Construction

[0008] The preparation method of the present invention is the following steps:

[0009] ①. Melt the water-soluble paraffin at 85°C, add 10% carbon black powder with a diameter of 1-5 microns to the molten paraffin, and stir it evenly as the cortex for spinning;

[0010] ②. The above-mentioned paraffin mixed melt and acrylic fiber spinning solution are metered online by a metering pump respectively, and then supplied to the spinning part of the skin-core mechanism for spinning to form a composite yarn with a skin-core structure. The supply of paraffin is 25% of the acrylic fiber spinning solution ;

[0011] ③. After spinning and stretching, the obtained fiber is dewaxed in hot water, the temperature of the hot water is 80°C, and the time is 5 minutes;

Embodiment 1

[0014] Ingredients: 75% acrylic fiber, 22.5% paraffin wax, 2.5% carbon black powder;

[0015] Preparation:

[0016] ①. Melt the water-soluble paraffin at 85°C, add 10% carbon black powder with a diameter of 1-5 microns to the molten paraffin, and stir it evenly as the cortex for spinning;

[0017] ②. The above-mentioned paraffin mixed melt and acrylic fiber spinning solution are metered online by a metering pump respectively, and then supplied to the spinning part of the skin-core mechanism for spinning to form a composite yarn with a skin-core structure. The supply of paraffin is 25% of the acrylic fiber spinning solution ;

[0018] ③. After spinning and stretching, the obtained fiber is dewaxed in hot water, the temperature of the hot water is 80°C, and the time is 5 minutes;

Embodiment 2

[0020] Ingredients: cupro ammonia fiber 80%, paraffin wax 18%, carbon black powder 2%, its preparation method is the same as embodiment one.

[0021] To sum up, the chemical synthetic fiber of the present invention uses cupro ammonia fiber, paraffin wax, carbon black powder, etc. as raw materials, has a convex and concave appearance, solves the matting problem of synthetic fibers, has low cost, and has strong weavability.

Abstract

The invention provides a brand novel weaving concept of chemical synthetic fibers and a method thereof. Copper ammonia fibres, paraffin, carbon black powder, etc. are used as raw materials; the fibers spinning by dissolution method such as nitrilon, copper ammonia fibres, vinylon, etc. are used; single hole spinning is changed into compound spinning by spinning parts with a sheath-core structure when the spinning is non-compound spinning, which can obviously improve weaving performance; the outer layer of the spinning uses water-soluble paraffin and the surface of the fibers reserves concave-convex appearance caused by atoms at the same time when the paraffin is removed. The invention does not influence fiber color and has low cost and strong weaving capacity.

Description

technical field [0001] The invention relates to a weaving method of chemical synthetic fiber fabric, especially a weaving method of weaving chemical synthetic fiber with uneven surface by physical method. Background technique [0002] The surface state of chemical synthetic fibers is generally smooth and smooth, with mirror luster and waxy feeling. When this fiber is used as a special fabric or application, it cannot achieve the desired effect. Generally, it is added to the melt-spun composite A variety of inorganic substances, such as silicon dioxide, titanium oxide, etc. (that is, matting), are effective for matting synthetic fibers, but have an impact on the color of the fibers. Excessive addition of matting agents will affect the mechanical properties of the fibers. Subjecting the surface of the fiber to glow discharge plasma radiation makes the fiber have an uneven surface, but the cost is too high and the practicability is not strong.
