Embodiment 1

[0020] The protective sleeve with radiation protection function, its preparation method comprises the following steps:

[0021]1) Put the polyester fibers into acetone and ethanol for ultrasonic cleaning for 15 minutes, wash with deionized water and then dry; put them in 1.5mol / L NaOH solution, stir magnetically at 55°C for 15 minutes, wash with deionized water and then dry ; Put the quantitative fiber into the solution containing 0.05mol / LSnCl 2 , 0.2mol / L HCl solution, magnetically stirred for 10min, washed with deionized water and dried; prepared 0.03mol / LAgNO 3 solution and 2mol / L ammonia solution according to the mass ratio of silver ammonia solution of 1:3, put the polyester fiber in the silver ammonia solution for 20min magnetic stirring, wash with deionized water and then dry it for later use; 2) First, the activated polyester The fiber is fixed in the silver salt solution, and the reducing solution twice as much as the silver salt solution is slowly dropped in while ...

Embodiment 2

[0023] The preparation method of the protective sleeve with radiation protection function comprises the following steps:

[0024] 1) Fiber pretreatment: Put the polyester fiber in acetone and ethanol for ultrasonic cleaning for 20 minutes, wash with deionized water and then dry; put it in 2.0mol / L NaOH solution, stir magnetically at 60°C for 25 minutes, and then dry it with deionized water Dry after cleaning; put the quantitative fiber into the 2 , 0.5mol / L HCl solution, magnetically stirred for 15min, washed with deionized water and dried; prepared 0.04mol / LAgNO 3 solution and 3mol / L ammonia solution according to the mass ratio of silver ammonia solution of 1:5, the polyester fiber is placed in the silver ammonia solution and magnetically stirred for 30min, washed with deionized water and dried for later use; pretreatment can remove oil stains and Impurities, using silver ammonia solution to activate the surface of the fiber, abandoning the expensive metal palladium, which n...

Embodiment 3

[0032] Protective sleeve with anti-radiation function. The protective sleeve is made of 30% polyurea microcapsule / PP blend spinning and silver-plated polyester fiber, which is cut and sewn. The protective sleeve not only has the function of self-heating, but also can effectively shield High and low frequency radiation with large fluctuations can be applied to special work occasions to protect the body from radiation hazards. At the same time, its self-heating function can keep the body warm. The heat transfer speed and self-heating sensitivity are high, which expands the application of radiation protection fabrics scope.

[0033] The preparation method of the protective sleeve with radiation protection function includes: fiber pretreatment, silver plating, preparation of emulsion, preparation of polyurea microcapsules, and weaving, specifically including the following steps:

[0034] Fiber pretreatment: Put the polyester fiber into acetone and ethanol for ultrasonic cleaning f...

Abstract

The invention discloses a protection sleeve with a radiation protection function and a preparation method thereof. The protection sleeve is made by weaving, cutting and sewing 28-32% polyurea microcapsule / PP blended spun yarn and silver-plated polyester fibers. The preparation method of the protection sleeve comprises the steps that firstly, the surfaces of polyester fibers are degreased, decontaminated and activated; secondly, the polyester fibers are immersed in a silver salt solution and a reducing solution for silver plating to obtain the silver-plated fibers, and an O / W emulsion is prepared separately; thirdly, an aqueous solution of diethylenetriamine and 3,5-difluorobenzoic acid is added, and washing and drying are conducted after a reaction to obtain polyurea microcapsule powder; finally, the 28-32% polyurea microcapsule / PP blended spun yarn is prepared, and the 28-32% polyurea microcapsule / PP blended spun yarn and the silver-plated polyester fibers are woven, cut and sewn intothe protection sleeve. The protection sleeve has the advantages that silver plating layers of the polyester fibers of the protection sleeve are uniform and compact, and the protection sleeve can effectively prevent the penetrating power of radiation and effectively shield high-and-low frequency radiation without large fluctuations and has a self-heating function at the same time.

Description

technical field [0001] The invention relates to the field of preparation of special functional sleeves, in particular to a protective sleeve with radiation protection function and a preparation method thereof. technical background [0002] Protective sleeves, also known as cuffs and sleeves, are sleeves worn outside the sleeves to protect the sleeves of clothes. A sleeve usually worn loosely over the other sleeve. It is suitable for kitchen work and cleaning, and the dirt stuck on it is easy to remove, easy to use, and never worry about various oil stains. It is also very suitable for students, for example, it can avoid getting pen and ink on the sleeves. Sleeves can be classified into the following three types according to the fabric used: Cotton fabric: mostly pure cotton, knitted cotton, coral fleece, quilted cotton, etc. The sleeves made of cotton fabric are soft and do not hurt the skin, but because they are not Waterproof and dirt-resistant, need to be changed frequ...
