Preparation method of stereoscopic natural bright microfiber material and products thereof by lustring

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
