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.
