Problems solved by technology

In addition, static electricity will absorb a variety of viruses, bacteria and harmful substances contained in dust in the air, affect the human respiratory system, bring a lot of discomfort to patients with respiratory diseases, and even cause bronchitis and asthma in severe cases; and lasting It will increase the alkalinity of human blood, reduce blood calcium, and increase urinary calcium excretion, which is very unfavorable to patients with low blood calcium levels, especially for the elderly with cardiovascular system diseases, static electricity is more likely to cause aggravated or induced premature

Embodiment 1

[0028] (1) Feather pretreatment: immerse the selected feathers in the cleaning agent, remove them after 10 minutes, and then rinse them with clean water to remove the dust and impurities attached to the feathers;

[0029] (2) Feather powder preparation: add water to 25g of feathers after pretreatment to adjust its water content at 65-70%, then add 3g of pregelatinized starch, mix well and send it to a freeze dryer, and dry the resulting solid through ultramicro The pulverizer makes fine powder, and then it is ground into nano-scale powder by nano ball mill, that is, feather powder;

[0030] (3) Preparation of silky down fiber: add 70g 5wt% peracetic acid solution to the 25g feather powder of the above-mentioned gained, fully mix and soak for 24h, and microwave reflux treatment at microwave frequency 2450MHz, output power 700W for 10min, filter while hot, The obtained filtrate was naturally cooled to room temperature, and then the pH value of the filtrate was adjusted to 7 with...

Embodiment 2

[0037] (1) Feather pretreatment: immerse the selected feathers in the cleaning agent, remove them after 10 minutes, and then rinse them with clean water to remove the dust and impurities attached to the feathers;

[0038] (2) Feather meal preparation: add water to 30g of feathers after pretreatment to adjust its water content at 65-70%, then add 3g of pregelatinized starch, mix well and send it to a freeze dryer, and dry the resulting solid through ultramicro The pulverizer makes fine powder, and then it is ground into nano-scale powder by nano ball mill, that is, feather powder;

[0039] (3) Preparation of filamentous down fiber: add 80g 5wt% peracetic acid solution to the above-mentioned gained 30g feather powder, soak for 24h after fully mixing, and process 10min under microwave reflux at microwave frequency 2450MHz, output power 700W, filter while hot, The obtained filtrate was naturally cooled to room temperature, and then the pH value of the filtrate was adjusted to 7 by...

Embodiment 3

[0072] Taking the same batch of feathers as raw materials, the down composite fibers were prepared by the methods of Example 1, Example 2, Comparative Example 1, Comparative Example 2 and Comparative Example 3 respectively, and the comparative example 4 without modification treatment was set at the same time, and the determination The method is used to remove dust and impurities on feathers in the feather pretreatment stage, and measure the antistatic performance of the prepared down composite fiber. The results are shown in Table 1.

[0073] The application performance of down composite fiber preparation method described in table 1 embodiment and comparative example

Abstract

The invention discloses anti-static down feather composite fibers for down and feather filled products and relates to the technical field of down feather processing. A preparation method comprises the following steps: (1) pre-treating feather; (2) preparing feather powder; (3) preparing threadlike down feather fibers; (4) modifying the down feather fibers; and (5) forming the down feather compound fibers. On the basis of original light and soft properties and heat insulating ability of the down feather fibers, the down feather composite fibers which are excellent in anti-static property are prepared. Static electricity caused by friction of common down feather fibers and down feather fibers as well as the down feather fibers and a shell fabric of a product is avoided, the using comfort of the down feather product filled by the down feather composite fibers is enhanced, and discomfort caused by static electricity on a human body is reduced.

Description

[0001] Technical field: [0002] The invention relates to the technical field of down processing, in particular to an antistatic down composite fiber for processing down products. [0003] Background technique: [0004] Natural protein fibers used in textiles usually include wool, rabbit hair, camel hair, yak hair, mohair and silk, etc., while down is often only used as filler for clothing and bedding. As a natural protein fiber, down fiber has the characteristics of softness, light weight, and good warmth retention, so it is widely used as a filling material for thermal textile products. [0005] Static electricity is a problem that still needs to be solved in down products. Wearing or using down clothing and bedding in the dry season is prone to static electricity. When the human body touches metal objects, it will feel electrified. In addition, static electricity will absorb a variety of viruses, bacteria and harmful substances contained in dust in the air, affect the human...
