Problems solved by technology

[0002] At present, Dingdao sea-island fiber is used to produce superfiber materials. Due to the existing process characteristics, the dimensional stability and physical indicators of 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

[0046] In this embodiment, the preparation process of the graphene-containing superfiber material is mainly realized through the following steps:

[0047] Step 1 Preparation of fiber batt: fiber A, fiber B and fiber C are opened, initially mixed, opened for the first time, metal detection, mixed and opened for the second time, so that the fibers are snowflake-shaped, and the snowflake-shaped fiber is made into a fiber batt with a certain density.

[0048]Among them, the weight ratio of fiber is: the weight ratio of fiber is: fiber A is 86-88 parts of 3.5D×51mm polyester sea-island fiber, fiber B is 4-4.5 parts of modified high-shrinkage polyester fiber, fiber C is 4-6 parts of graphene fibers. Graphene fiber can adopt the products on the existing market. Preferably, graphene fibers can be replaced by composite graphene fibers compounded with protein synthetic fibers. The protein synthetic fiber adopts composite protein synthetic fiber, or is called protein synthetic composi...

Embodiment 2

[0070] 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.

[0071] step 1

[0072] Fiber A, fiber B and fiber C are mixed together for the opening step.

[0073] Preferably, fiber A is subjected to an opening step, fiber B and fiber C are mixed together for an opening step, and then fiber A, fiber B and fiber C are mixed together for a preliminary mixing step.

[0074] step 2

[0075] The needle density of pre-acupuncture is 90-92 needles / cm 2 , The acupuncture depth is 8.2-8.5mm.

[0076] Preferably, the front and back needling steps use front and back needling boards, and the needling density of the front and back needling boards is 270-280 pricks / cm 2 , the needling depth is 5.5-6mm, and the needling density of anti-thorn board is 420-450 thorns / cm 2 , Acupuncture depth is 8.2 ~ 8.5mm....

Abstract

The invention discloses a preparation method of a graphene-containing microfiber material. The preparation method comprises 1, preparing a fiber bat from figured sea-island polyester fibers, modified high shrinkage polyester fibers and graphene fibers, 2, preparing a base fabric, 3, immersing the base fabric in polyvinyl alcohol, 4, immersing the base fabric in PU, 5, carrying out alkali reduction treatment, and 6, carrying out functional agent treatment dry process overlaying, wherein the overlaying layer is prepared through orderly coating a carrier with surface layer slurry to obtain a surface coating, coating the surface coating with middle layer slurry to obtain a middle coating, coating the middle coating with graphene-containing slurry to obtain a bottom coating and coating the bottom coating with binder layer slurry to obtain a binder coating. The invention also discloses a preparation technology using the graphene-containing microfiber material and product. Through use of graphene, physical property indexes such as elasticity, toughness, tearing strength, wear resistance and tear resistance are improved and bacterial inhibition effects are obtained. The physical property indexes of the product with the graphene-containing microfiber material are significantly higher than those of similar products and can be widely used in special equipment such as for protection and military shoes, apparels and equipment.

Description

technical field [0001] The invention relates to a superfiber material and a product, in particular to a preparation process of a superfiber material and a product. Background technique [0002] At present, Dingdao sea-island fiber is used to produce superfiber materials. Due to the existing process characteristics, the dimensional stability and physical indicators of 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. Especially for special equipment, such as military shoes, clothing, equipment and other microfiber materials, its physical indicators such as wear resistance, tearing, and maximum tension are particularly important. [0003] Therefore, it is necessary to develop a superfiber material that can improve physical properties. Contents of the invention [0004] In view of this, th...
