Embodiment 1

[0023] Kapok fiber pretreatment: hydrogen peroxide 8g / L, TAED 4g / L, sodium carbonate 2g / L, treatment temperature 80°C.

[0024] Corona treatment: The corona treatment voltage is 8kV, the time is 30s, the treatment time corresponds to each set of voltage is 14s / 3cm, and the treatment temperature is 60°C.

[0025] Specific operation: immerse the kapok fiber in the pretreatment solution, treat it at 80°C for 60 minutes, then take it out, wash it with water and dry it. Then the kapok fiber after pretreatment is placed on the A201 comber and combed for 1 pass. The combed kapok fibers are placed on a corona discharge apparatus, and processed according to the above corona treatment conditions.

Embodiment 2

[0027] Kapok fiber pretreatment: pretreatment condition is the same as embodiment 1.

[0028] Corona treatment: the corona treatment voltage is 10kV, the time is 40s, the treatment time corresponds to each group of voltage is 16s / 3cm, and the treatment temperature is 80°C.

[0029] Specific operation: immerse the kapok fiber in the pretreatment solution, treat it at 80°C for 60 minutes, then take it out, wash it with water and dry it. Then the kapok fiber after pretreatment is placed on the A201 comber and combed for 1 pass. The combed kapok fibers are placed on a corona discharge apparatus, and processed according to the above corona treatment conditions.

Embodiment 3

[0031] Kapok fiber pre-treatment: hydrogen peroxide 10g / L, TAED 6g / L, sodium hydroxide 2g / L, treatment temperature 80°C.

[0032] Corona treatment: The corona treatment voltage is 8kV, the time is 30s, the treatment time corresponds to each set of voltage is 14s / 3cm, and the treatment temperature is 60°C.

[0033] Specific operation: immerse the kapok fiber in the pretreatment solution, treat it at 90°C for 60 minutes, then take it out, wash it with water and dry it. Then the pre-treated kapok fiber is placed on the A201 comber for 2 passes. The combed kapok fibers are placed on a corona discharge apparatus, and processed according to the above corona treatment conditions.

Abstract

The invention relates to a novel method for improving the moisture absorption performance of kapok fiber by using corona treatment technology to modify the surface of the kapok fiber. The method comprises the following steps: subjecting the kapok fiber to pretreatment with a mixture of 6 to 10 g / L of hydrogen peroxide and 4 to 8 g / L of tetraacetyl ethylenediamine (TAED) so as to remove wax and impurities on the surface of the kapok fiber, which allows the kapok fiber to have certain whiteness; and then combing the kapok fiber having undergone pretreatment and then placing the kapok fiber on a corona discharge instrument for discharging treatment of the kapok fiber, wherein treatment voltage is 6 to 12 kV, treatment time corresponding to each group of treatment voltage is 5 to 20 s / cm<3>, and treatment temperature is 30 to 110 DEG C. According to the invention, active groups like hydroxyl groups, carboxyl groups, epoxide groups and peroxide are creatively introduced onto the surface of the kapok fiber having undergone corona treatment, so the properties like moisture absorption, dyeing and bonding properties of the surface of the kapok fiber are effectively improved.

Description

technical field [0001] The invention relates to a new technology for improving the hygroscopicity of kapok fiber surface by corona treatment technology. Background technique [0002] Kapok fiber is the thinnest, lightest, highest hollow and warmest fiber material among natural ecological fibers. Its fineness is only 1 / 2 of cotton fiber, but the hollow rate reaches more than 80%, which is 2-3 times that of ordinary cotton fiber. [0003] Kapok fiber has the characteristics of antibacterial, smooth, mildew-proof, moth-proof, soft, impermeable, not easy to tangle, non-thermal conduction, ecological, warm, and strong hygroscopicity. However, kapok fiber has poor spinnability and is generally difficult to spin purely. Moreover, its poor hygroscopicity leads to poor dyeability, and there are few types of pigments that can be used for dyeing. [0004] Kapok fabric is favored by people because of its ecology, warmth and softness. However, in the current dyeing and finishing proces...
