Embodiment 1

[0038] The average particle size of the cleaned kapok fiber powder is 68.5 μm, soaked in 35% sodium hydroxide aqueous solution at a ratio of 1:2.5,

[0039] Mix the kapok fiber powder thoroughly and disperse in an ultrasonic oscillator for 4.5 hours at a temperature of 26°C. A kapok fiber powder solution is obtained.

[0040] In addition, the cellulose bamboo pulp with a polymerization degree of 550 is prepared by conventional cellulose viscose preparation processes such as alkali staining, pressing, crushing, aging, yellowing, dissolving, mixing, filtering, aging and degassing to obtain cellulose viscose spinning Stock solution, control the composition of this viscose spinning stock solution to be α cellulose 8.8%, contain alkali 4.5%.

[0041] Then get the kapok fiber powder solution and the cellulose spinning stock solution according to the production needs, mix and pass through no less than 10 minutes in a static mixer. 5 Mix for the first time to mix evenly. After pre-f...

Embodiment 2

[0043] Take the cleaned kapok fiber powder with an average particle size of 72.8 μm, soak it in 30% sodium hydroxide aqueous solution at a ratio of 1:3, fully mix the kapok fiber powder, and disperse it in an ultrasonic oscillator for 5 hours. is 25°C. A kapok fiber powder solution is obtained.

[0044] In addition, the cellulose hemp pulp with a degree of polymerization of 580 and the cellulose bamboo pulp with a degree of polymerization of 750 are processed by alkali staining, pressing, crushing, aging, yellowing, dissolving, mixing, filtering, aging and degassing. The cellulose viscose spinning stock solution is obtained in the viscose preparation process, and the composition of the viscose spinning stock solution is controlled to be 8.8% of α-cellulose and 4.5% of alkali.

[0045] Then get the kapok fiber powder solution and the cellulose spinning stock solution according to the production needs, mix and pass through no less than 10 minutes in a static mixer. 5 Mix for t...

Embodiment 3

[0047] Take the cleaned kapok fiber powder with an average particle size of 72.8 μm, soak it in 30% sodium hydroxide aqueous solution at a ratio of 1:3, fully mix the kapok fiber powder, and disperse it in an ultrasonic oscillator for 5 hours. is 25°C. A kapok fiber powder solution is obtained.

[0048] In addition, the cellulose bamboo pulp with a degree of polymerization of 780 and the cellulose straw pulp with a degree of polymerization of 450 are subjected to alkali staining, pressing, crushing, aging, yellowing, dissolving, mixing, filtering, ripening and degassing. The cellulose viscose spinning stock solution is obtained in the plain viscose preparation process, and the composition of the viscose spinning stock solution is controlled to be 8.8% of α-cellulose and 4.5% of alkali.

[0049] Then get the kapok fiber powder solution and the cellulose spinning stock solution according to the production needs, mix and pass through no less than 10 minutes in a static mixer. 5...

Abstract

The invention relates to a composite fiber of kapok fiber powder and cellulose and a preparation method thereof, in particular to a preparation method of kapok fiber powder modified cellulose composite fiber; the method provided by the invention comprises cleaning the kapok fiber powder , the cleaned kapok fiber powder, cellulose polymer, various additives, and solvents are prepared into a spinning solution, and the kapok fiber powder and cellulose composite fiber are obtained by wet spinning through coagulation bath spinning. The invention prepares the kapok fiber powder and cellulose composite fiber with low production cost and excellent performance by adding different contents of kapok fiber powder to spinning solution and changing process conditions. The preparation method of kapok fiber powder and cellulose composite fiber of the present invention will solve the problem of difficult spinning of kapok fiber, maintain the advantages of hollow kapok fiber to keep warm, natural antibacterial, etc., and effectively use kapok fiber to expand its application field of clothing.

Description

technical field [0001] The invention relates to a functional fiber material, in particular to a composite fiber of kapok fiber powder and cellulose, and a preparation method of the composite fiber. Background technique [0002] As the earliest man-made fiber, cellulose fiber has a history of more than 100 years, and the current output of cellulose fiber has reached more than 2.6 million tons. Cellulose fibers produced by nature have attracted much attention. However, because the traditional cotton and hemp natural cellulose fibers have certain limitations in the development scale, such as the problem of cotton "competing for land with grain", people are focusing more and more on new natural and regenerated cellulose fibers. development and utilization. [0003] Kapok fiber is a kind of fruit fiber of the woody plant kapok tree, which is attached to the inner wall of the kapok capsule shell and developed and grown from the inner wall cells. The adhesion force between the f...
