Problems solved by technology

[0002] Due to the existing process characteristics of the current microfiber materials, the physical indicators such as waterproof and breathable of the superfiber materials are not ideal.
Therefore, the existing microfiber materials are generally suitable for low-end products and cannot be applied to high-end products, which further limits the application prospects of superfiber materials.

Embodiment 1

[0028] In this embodiment, the preparation process of the waterproof and breathable superfiber material is mainly realized through the following steps:

[0029] Step 1: 80-85 parts by weight of nylon 6, 8-15 parts by weight of protein synthetic fiber, 90-95 parts by weight of low-density polyethylene, 3-8.5 parts by weight of modified fluororesin, and 5-35 parts by weight of conductive functional masterbatch Mixing and preparing adventitious island-in-the-sea short fibers according to conventional techniques. For example: successively go through the processes of melt extrusion, spinning, oiling, drawing, crimping, shaping and cutting. The conductive functional masterbatch can be the product of Shenzhen Jianyang Plastic Chemical Co., Ltd., or the product of Dongguan Suheng Plastic Co., Ltd. Preferably, the protein synthetic fiber is composite protein synthetic fiber, or called protein synthetic composite fiber, which includes various animal proteins, and is mainly made of the ...

Embodiment 2

[0038] The main difference between the present embodiment and the first embodiment is that the present embodiment has further optimized the process parameters of each step in the first embodiment, and the similarities will not be repeated here.

[0039] In step 1:

[0040] The components by weight of the conductive functional masterbatch are as follows: 15-35 parts of conductive powder, 5-8 parts of nano-silver, 6.5-8.5 parts of coupling agent, 8.5-15 parts of dispersant, 35-80 parts of carrier resin; The components in parts by weight of the body are as follows: 30-55 parts of tin oxide and 30-55 parts of antimony oxide.

[0041] Wherein, the average particle size of the conductive powder is less than 2 microns. The coupling agent is aluminate, titanate or aluminum-titanium composite coupling agent. The dispersant is PE polymer wax or PP molecular wax. The carrier resin is PP resin.

[0042] The conductive functional masterbatch is prepared as follows: mix tin oxide and an...

Abstract

The invention discloses a preparation process of a waterproof and breathable microfiber material. The process comprises the steps of, 1, mixing, by weight part, 85-90 parts of nylon 6, 8-15 parts of protein synthetic fiber, 90-95 parts of low-density polyethylene, 3-8.5 parts of modified fluororesin and 5-35 parts of conductive functional masterbatch to prepare unfigured sea-island short fibers through conventional processes; 2, preparing conductive non-woven fabrics through conventional processes; 3, performing impregnation, solidification and washing treatment to obtain base fabrics containing polyurethane; 4, performing splitting treatment to obtain semi-finished products; 5, performing impregnation, padding, preliminary drying, drying and after-treatment to obtain the finished microfiber material. Impregnation liquor applied during the steps is waterproof and oil proof soft finishing liquor containing C6 three-proofing finishing agent and protein powder. The microfiber material and product produced through the preparation process obtains ideal physical indexes such as waterproofness and breathability, which are significantly higher than those of like products, and meanwhile is soft and rich in hand feeling, thereby being applicable to high-grade products and further broadening the application prospect of microfiber materials and products.

Description

technical field [0001] The invention relates to a superfiber material and a product, in particular to a preparation process of a waterproof and breathable superfiber material and a product. Background technique [0002] Due to the existing process characteristics of the current microfiber materials, the physical indicators such as waterproof and air permeability of the superfiber materials are not ideal. Therefore, existing microfiber materials are generally suitable for low-end products, but cannot be applied to high-end products, which further limits the application prospects of superfiber materials. [0003] Therefore, it is necessary to develop a superfiber material that can both improve waterproof and air permeability. Contents of the invention [0004] In view of this, the object of the present invention is to provide a preparation process of a waterproof and breathable waterproof and breathable superfiber material. [0005] The invention also provides a waterproof...
