An antistatic stitch-bonded nonwoven material and its manufacturing method

Abstract

The invention discloses an anti-static loop bonding non-woven material and a production method of the anti-static loop bonding non-woven material. The anti-static loop bonding non-woven material comprises 20-50 wt% of viscose and 50-80 wt% of regenerated polyester fiber. The production method comprises the following steps of (1) selecting 20-50 wt% of the viscose and the 50-80 wt% of regenerated polyester fiber to serve as a raw material, (2) obtaining a loop bonding non-woven base cloth through opening, mixing, carding, lapping and loop bonding strengthening, (3) obtaining the loop bonding non-woven material through twice afterfinish and treatment of the loop bonding non-woven base cloth, wherein the specific resistance of the front surface of the loop bonding non-woven material and the specific resistance of the back surface of the loop bonding non-woven material are respectively below 107. The anti-static loop bonding non-woven material has a permanent anti-static function on the basis of excellent moisture absorption performance of the viscose, the strength index of the product is further guaranteed through the regenerated polyester fiber, and carding of a carding technique is conveniently conducted. According to the anti-static loop bonding non-woven material and the production method of the anti-static loop bonding non-woven material, the problems that an anti-static function of a traditional non-woven material depends on an anti-static agent, a physical index of the product is affected, and an anti-static effect is reduced and even lost after being used for a time are solved.

Description

technical field [0001] The invention relates to the field of stitch-bonded nonwoven materials, and more specifically relates to an antistatic stitch-bonded nonwoven material and a manufacturing method thereof. Background technique [0002] Most of the existing antistatic non-woven materials are made of regenerated polyester fiber, and the non-woven base fabric is obtained through the needle punching process, and then the finishing liquid is glued and heat-set, and a large amount of A large amount of antistatic agent, so that the surface of the nonwoven material obtained after finishing is attached with a large amount of antistatic agent, so as to achieve the purpose of antistatic. [0003] The above method is not only cumbersome and difficult to implement, but also because the antistatic agent is attached to the surface of the base fabric, that is, its antistatic effect is not a characteristic of the base fabric itself, so in the later use process, the antistatic agent will ...
