Problems solved by technology

The traditional water-repellent finishing method of textiles mainly uses fluorine-containing finishing agents to achieve the purpose of water-repelling by reducing the free energy of the fabric surface, but such finishing agents are expensive, and organic fluorine has certain biological toxicity, which is harmful to the human body and the environment. potential hazard
After the fabric is treated with organic fluorine, although it can significantly reduce the surface energy of the fabric, it cannot improve the microscopic roughness of the fabric surface, and it is difficult to meet the long-term water repellency requirements.

Embodiment 1

[0025] The nano water-repellent and antifouling down work clothes in the present embodiment comprise an outer fabric, an inner fabric, and a down filling layer arranged between the outer fabric and the inner fabric; the preparation method of the down work clothes comprises the following steps:

[0026] (1) The ordinary polyimide fiber is pickled with salicylic acid for 30 minutes, then taken out and drained, impregnated with ammonium chloride for 20 minutes, and then put into a continuous carbonization furnace with a temperature of 800 ° C and nitrogen atmosphere for 40 minutes. Finally, put it into a 400°C steam activation furnace for heating treatment for 30 minutes to obtain modified polyimide fibers, then compound the modified polyimide fibers and cotton fibers to obtain a built-in layer, and then coat the high-density spun and built-in layers After the cloth is glued and hot-bonded and pressed, put it on the reel in the vacuum chamber of the coating equipment, close the ch...

Embodiment 2

[0031] The nano water-repellent and antifouling down work clothes in this embodiment comprise an outer fabric, an inner fabric, and a down filling layer arranged between the outer fabric and the inner fabric; the preparation method of the down work clothes comprises the following steps:

[0032] (1) The common polyimide fiber was acid-washed with salicylic acid for 20 minutes, then drained and impregnated with ammonium chloride for 30 minutes, and then put into a continuous carbonization furnace with a temperature of 600 ° C and a nitrogen atmosphere for heat treatment for 60 minutes. Finally, put it into a 500°C steam activation furnace and heat it for 20 minutes to obtain modified polyimide fibers, then compound the modified polyimide fibers and cotton fibers to obtain a built-in layer, and then coat the high-density pongee and built-in layers After the cloth is glued and hot-bonded and pressed, put it on the reel in the vacuum chamber of the coating equipment, close the cham...

Abstract

The invention relates to a nano water-repellent antifouling down working clothes, and belongs to the technical field of down jackets. The nano water-repellent antifouling down working clothes comprises an outer-layer fabric, an inner-layer fabric and a down filling layer arranged between the outer-layer fabric and the inner-layer fabric, wherein the outer-layer fabric is formed by compounding a gray fabric layer and a built-in layer, a nano water-repellent coating is arranged on the surface of the gray fabric layer, the inner-layer fabric is formed by compounding a cotton cloth layer and a nano waterproof layer which are treated by a decontamination finishing liquid, and the down filling layer comprises at least two layers of water-repellent down and at least three layers of lining latticed fibers. According to the nano water-repellent antifouling down working clothes, through the outer-layer fabric, the inner-layer fabric and the down filling layer, the down jacket has the functions of water repellency, antifouling, flame retardance, static resistance, breathability, acid and alkali resistance and the like, compared with a common down jacket, the performance is more excellent, and the nano water-repellent antifouling down working clothes are suitable for outdoor work and use in winter.

Description

technical field [0001] The invention belongs to the technical field of down jackets, in particular to a nano water-repellent and anti-fouling down work clothes. Background technique [0002] Water-repellent down jackets appear on the market, which is to carry out water-repellent finishing on the down jacket fabrics. The traditional water-repellent finishing method of textiles mainly uses fluorine-containing finishing agents to achieve the purpose of water-repelling by reducing the free energy of the fabric surface, but such finishing agents are expensive, and organic fluorine has certain biological toxicity, which is harmful to the human body and the environment. Potentially hazardous. After the fabric is treated with organic fluorine, although the surface energy of the fabric can be significantly reduced, the microscopic roughness of the fabric surface cannot be improved, and it is difficult to meet the long-term water repellency requirement. [0003] In order to maintain...
