Antistatic breathable down used for down jackets and a preparing method thereof

Abstract

Antistatic breathable down used for down jackets and a preparing method thereof are disclosed. The method includes adding down into a cyclodextrin-containing solution to perform crosslinking modification; soaking the modified down in an antistatic agent solution having a concentration of 18-22 g / L; and adding the down subjected to antistatic treatment into a hydrogen peroxide solution having a concentration of 35-40 mL / L to bleach the down so as to obtain the antistatic breathable down used for down jackets. Beneficial effects of the antistatic breathable down and the method are that the antistatic breathable down has good antistatic performance and air permeability; an antistatic agent is strongly adhered to the down; the down is washable and warm keeping performance of the down is not influenced; a down product is made not swollen, thick or solid, thus increasing beauty and comfort sense; the down has a great market potential; the down modified with cyclodextrin is more liable to react in an aqueous solution; and grafted cyclodextrin contains a large amount of hydroxy and can increase the number of reactive hydroxy on the surface of the down.

Description

Technical field [0001] The invention relates to the field of clothing fabrics, in particular to an antistatic and breathable down for down wear and a preparation method thereof. Background technique [0002] Natural down is a branch-shaped fiber with a fractal structure. Because of its shape characteristics, the down aggregate has the characteristics of efficient heat insulation and warmth, elasticity and fluffy, soft and easy to slip, but pure down has the following shortcomings: down It is a rare resource with limited output and high price, especially in special periods such as avian influenza, when the cost of down is soaring; down is like a velvet, without entanglement between each other, so it is easy to flow, and the stability is extremely poor; down-like feathers and breaks The root tip of the feather twigs and the fine barbs of the down will inevitably cause the down fiber to easily drill down, and leak and leak; the down is a protein fiber, and if it is not strictly disi...

Problems solved by technology

[0002] Natural down is a branch-shaped fiber with a fractal structure. Because of its shape characteristics, the down aggregate has the characteristics of efficient heat insulation and warmth, elasticity and fluffy, soft and easy to slide, but pure down has the following disadvantages: down It is a rare resource with limited output and high price. Especially in special periods such as bird flu, the cost of down is soaring; the down is in the shape of a flower, and there is no entanglement with each other, so it is easy to flow and has extremely poor stability; down barbs and broken The tip of the root of the barb and the fine barbs of the down will inevitably lead to the easy drilling of the down fiber, and leakage and leakage; the down is a protein fiber, and if it is not strictly sterilized, it is easy to cause moths and mildew; Due to performance limitations such as tree-branch shape and structure, it is almost not suitable for direct spinning, and can only be used as filling material; traditionally used down products are bulky and thick, and usually need quilting to solve their fixation, which makes the appearance of feather products obsolete and outdated. limit its demand for fashion and consumption

[0003] The prior art, such as the Chinese invention patent with the authorized announcement number CN 103011047 B, discloses a down lyocell and its processing method, which is composed of the following raw materials in weight percentage: down 1-99%, and the rest is lyocell fiber; The processing method is prepared through the processes of opening, spraying, drying, cooling and dust removal, and baling of the lyocell filler. The filler has the advantages of effective use of natural resources, energy saving, natural environmental protection, high cost performance, and economic benefits. , the product is soft and comfortable to the touch, has excellent moisture absorption and dehumidification, reduces unpleasant odor, has the characteristics of warmth and dryness, but the antistatic effect is poor, the product is bloated, and the comfort is not enough
