Problems solved by technology

[0004] However, the kapok fiber is short, ranging from 8mm to 34mm, the diameter of the middle section of the fiber ranges from 20m to 45m, and the linear density is low, ranging from 0.9 to 1.2tex
In terms of strength and elongation, kapok fiber has low strength, low elongation, poor surface smooth cohesion, and the fiber specific gravity is too light to be spun into yarn.
For a long time, due to the machinability of kapok fiber, kapok is used to make low-grade wadding products, which affects its development and utilization in the textile industry.

Embodiment 1

[0018] Example 1: After mixing water, silicone oil and crude oil in a mass ratio of 74:4:22, an auxiliary agent solution is obtained, and then the auxiliary agent solution is sprayed on the kapok fiber, and the kapok fiber sprayed with the auxiliary agent is placed at a humidity of 57%, the temperature is 30 ℃ environment, balance 25h, get the kapok fiber after pretreatment, in order to improve the spinnability of kapok fiber.

[0019] Then the kapok fiber is fed into Qingganglian equipment through weighing curtain feeding mechanism for opening, mixing and impurity removal.

[0020] The cotton web in Qingganglian carding machine is collected by the suction device and fed to the dust removal equipment for further dust removal and opening.

[0021] Connect the dedusting equipment with the spunlace line carding machine, card the fibers into a web on the spunlace line carding machine, then perform cross-laying, spunlace into cloth, and rolls, and then send the kapok cloth rolls di...

Embodiment 2

[0023] Example 2: Mix acrylate, starch, polyvinyl alcohol and water in a weight ratio of 40:40:20:300 to obtain a mixture of additives, heat it to 70°C, then add the kapok fiber to be treated, mix evenly, and then Use steam at 80°C to semi-set the kapok fibers for 25 minutes, spray the auxiliary agent mixture evenly on the surface of the kapok fibers, and obtain the pretreated kapok fibers after drying, so as to improve the spinnability of the kapok fibers.

[0024] Then kapok fiber and cotton fiber are fed into Qingganglian equipment according to the mass ratio of 70:30 through the weighing curtain feeding mechanism for opening, mixing and impurity removal.

[0025] The cotton web in Qingganglian carding machine is collected by the suction device and fed to the dust removal equipment for further dust removal and opening.

[0026] Connect the dedusting equipment with the spunlace line carding machine, card the fibers into a web on the spunlace line carding machine, then perfor...

Embodiment 3

[0028] Example 3: Mix acrylate, starch, polyvinyl alcohol and water in a weight ratio of 40:40:20:300 to obtain a mixture of additives, heat it to 70°C, then add the kapok fiber to be treated, mix evenly, and then Use steam at 80°C to semi-set the kapok fibers for 25 minutes, spray the auxiliary agent mixture evenly on the surface of the kapok fibers, and obtain the pretreated kapok fibers after drying, so as to improve the spinnability of the kapok fibers.

[0029] Then kapok fiber, polyester and man-made viscose fiber are fed into Qingganglian equipment according to the mass ratio of 60:10:30 through the weighing curtain feeding mechanism for opening, mixing and impurity removal.

[0030] The cotton web in Qingganglian carding machine is collected by the suction device and fed to the dust removal equipment for further dust removal and opening.

[0031] Connect the dedusting equipment with the spunlace line carding machine, card the fibers into a web on the spunlace line car...

Abstract

The invention belongs to the technical field of weaving, in particular to a production method of kapok fiber spunlaced nonwoven fabric. The method includes: pretreating kapok fiber to improve spinnability; using a weighing curtain feeder to feed kapok fiber into a blowing-carding device for opening, blending and purification; using an induced fan to collect web in a blowing-carding machine to feed into a tiny dust removing device for further dust removing and opening; connecting the tiny dust removing device with a spunlaced line carding machine, carding the fiber into web on the spunlaced line carding machine, cross lapping, spunlacing to form fabric, coiling, degreasing and bleaching, drying and slitting to obtain the finished product. The method is safe, environment-friendly, energy-saving, efficient, high in automation level, and advanced in spunlaced kapok nonwoven fabric weaving, and various characteristics of fiber raw materials are protected effectively.

Description

technical field [0001] The invention belongs to the technical field of weaving, and in particular relates to a production method of kapok fiber spunlace nonwoven fabric. Background technique [0002] Kapok fiber is a natural superfine and high hollow fiber. Its fiber hollowness is 80%, which is far more than other fibers. It has good warmth retention, high buoyancy, smooth and soft, not easy to tangle, impervious to water, no heat conduction, and strong adsorption capacity after degreasing. And the characteristics of strong moisture absorption and moisture conductivity. [0003] The hygroscopicity of kapok fiber is better than that of cotton fiber, and the standard moisture regain is 10%-10.73%. The main chemical components of kapok are volatile components, triterpenes and flavonoids, which have pharmacological properties such as antibacterial, anti-inflammatory, anti-tumor, and hepatoprotective effects. effect. Moreover, the specific gravity of kapok fiber is much smalle...
