Problems solved by technology

[0002] At present, Dingdao island fiber is used to produce superfiber materials. Due to the existing process characteristics, the dimensional stability, physical indicators, three-dimensional effect, leather surface texture effect, brightness, luster, etc. 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

[0045] In this embodiment, the preparation process of superfiber materials with three-dimensional natural light by scalding is mainly realized through the following steps:

[0046] 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.

[0047] Among them, fiber A is 90 parts by weight of 3.5D×51 mm polyester sea-island fiber, fiber B is 5 parts by weight of modified high-shrinkage polyester fiber, and fiber C is 5 parts by weight of polyester fiber.

[0048] Apply 0.32 to 0.38 parts by weight of an antistatic agent after the first opening and / or the second opening. The antistatic agent can be a polyester antistatic agent, which can reduce static electricity generated by the fiber. The antistatic agent can be the products of Binzhou Juli C...

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....

Embodiment 3

[0096] This embodiment mainly describes the scalding in detail, and other similarities with Embodiments 1 and 2 will not be repeated here.

[0097] Back cover coating, fourth drying and first scalding, wherein the fourth drying temperature is 85-88°C, the first scalding temperature is 105-120°C, preferably, the first scalding temperature is 112-120°C 115°C.

[0098] Undercoating, drying for the first time, and boiling for the second time, wherein, the drying temperature for the first time is 85-88°C, the temperature for boiling the second time is 105-120°C, preferably, the temperature for boiling the second time is 112°C ~115°C.

[0099] Intermediate coating and drying for the second time, wherein the drying temperature for the second time is 85-88°C.

[0100] The texture is painted and dried for the third time, wherein the temperature for the third time is 85-88°C.

[0101] Top coating, fourth drying and scalding, wherein, the fourth drying temperature is 85-88°C, and the ...

Abstract

The invention discloses a method for preparing a stereoscopic natural bright microfiber material by lustring, comprising the following steps: step one, preparing a fiber bat; step two, preparing base cloth; step three, carrying out impregnation via polyvinyl alcohol; step four, carrying out impregnation via PU by dipping an intermediate product prepared by the step three via wet polyurethane size, solidifying, washing at normal temperature, pre-drying for a second time, dipping via dispersoid, drying for a second time, washing with water at high temperature, drying and shaping to prepare a semi-finished product, wherein a solidification solution is dimethylformamide, and the dispersoid is water-soluble polyurethane dispersoid; step five, carrying out alkali minimization; and step six, carrying out leather facing effect treatment and treating via a functional agent. The invention also discloses a preparation method of the microfiber material and the products thereof. The prepared microfiber material and the products thereof are strong in texture stereoscopic feeling, natural in gloss and rich and full in hand feeling; various physical indexes such as peeling strength, abrasion resistance, tearing resistance, maximum tension force, yellowing resistance and breathability and the like are significantly higher than that of the similar products; the microfiber material and the products thereof can be widely applied to high-grade fashionable clothes, household articles and working articles.

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, physical indicators, three-dimensional effect, leather surface texture effect, brightness and luster 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. [0003] Therefore, it is necessary to develop a superfiber material that can not only improve physical properties, but also enhance the three-dimensional sense of leather surface texture, and produce light and natural luster. Contents of the invention [0004] In view of this, the object of the pre...
