Problems solved by technology

[0006] The lightness of protective clothing generally adopts the method of increasing micropores or reducing the thickness, which often leads to a decline in protective performance. The development of new special materials is also an important direction to reduce the density of protective clothing, but the research and development costs are high and the cycle is long

Embodiment 1

[0042] 1kg of epoxy resin is made into aqueous dispersion, 7kg of cellulose xanthate is dissolved in aqueous sodium hydroxide solution, and the two are mixed to form a liquid adhesive with a concentration of 70wt%.

[0043] Provide PET non-woven fabric 15kg, area density 35g / cm 2 , Porosity 85%. Provide two layers of aramid 1313 fiber textile layers with the same thickness, the total weight is 70kg, and the area density of each aramid fiber textile layer is 65g / cm 2 , Aramid fiber linear density 44tex.

[0044] Two layers of aramid fiber textile layer sandwich the PET non-woven layer to form a superimposed base fabric.

[0045] Add m-xylylenediamine to the liquid adhesive, and then apply the liquid adhesive to the superimposed base fabric, and use a roller or brush to apply pressure to promote the penetration of the liquid adhesive from the aramid fiber textile layer on one side to the Aramid fiber textile layer on the other side. During the infiltration process, the molec...

Abstract

Disclosed is lightweight protective clothing. The lightweight protective clothing is characterized by comprising a protective layer, the protective layer includes a PET (polyethylene glycol terephthalate) non-woven layer and an aramid fiber textile layer which are overlain, and epoxy resin and a cellulose chain penetrate the gap of the PET non-woven layer and the aramid fiber textile layer to havethe PET non-woven layer and the aramid fiber textile layer connected. The invention further provides a making method of the protective clothing and the protective clothing including protective clothes. The lightweight protective clothing and the protective clothes are light, high in strength, good in heat isolation, light and comfort in wear and good in protective performance.

Description

technical field [0001] The invention relates to a protective clothing and a fabric for the protective clothing, in particular to a light protective clothing and the fabric for the protective clothing. Background technique [0002] In terms of technology and use, protective clothing products mainly have the following development trends: [0003] 1) Multiple functions. In the production process of oil exploration, petroleum refining, chemical companies, electronic companies and other industries, operators often face multiple risks. This also requires protective clothing to have multiple protective functions to meet certain requirements. The protection requirements of some specific working environments, such as chemical protection, deflagration protection and arc protection. [0004] 2) Portability and comfort, so the portability and comfort of protective clothing are very important to the wearer. Typical applications such as operations in summer / high temperature environments...
