A kind of microfiber fabric and its manufacturing process

Abstract

A superfine fiber fabric, comprising a base part and a surface part, the base part is composed of fixed island type sea-island filaments or / and ordinary filaments, the surface part is composed of short fibers, and the fabric is the base part and the surface Partially intertwined nonwoven structure. A manufacturing process of superfine fiber fabrics, the island-fixed island-in-the-sea filaments or / and ordinary filaments of the base part are weft-knitted, warp-knitted or woven, and then a napping layer is formed on the surface through napping treatment. Lay short fibers on the layer, and use non-woven complexing technology to form a complex non-woven structure between short fibers and the brushed layer on the surface of the substrate, and then obtain superfine fiber fabrics through impregnation, drying, fiber opening, dyeing and post-treatment. The ultra-fine fiber fabric fills the gap in the finished product specifications of the needle-punched non-woven fabric with a thickness of less than 0.5mm, and has a very good two-color effect, high-grade and beautiful.

Description

technical field [0001] The invention relates to a superfine fiber fabric and a manufacturing process thereof, belonging to the technical field of high-grade textile fabrics. Background technique [0002] Microfiber is the abbreviation of superfine fiber PU synthetic leather. Sea-island superfine fiber is a type of superfine fiber, which is divided into two categories: sea-island filament and sea-island staple fiber (including fixed island type and indeterminate island type). Sea-island filaments generally produce suede fabrics through weaving and knitting, which are used in the production of clothing and apparel; sea-island staple fibers usually produce thick imitation leather fabrics through needle-punched non-woven, mainly used for shoemaking, sofas, and automotive interiors , clothing, etc. All microfiber fabrics are generally aimed at achieving high imitation leather. The fixed-island type super-fabric adopts alkali reduction fiber opening, which is safer and more envir...

AI Technical Summary

Problems solved by technology

[0003] Ordinary ultra-fine fiber needle-punched non-woven fabrics are usually made of ultra-fine staple fibers through the processes of unpacking, mixing, carding, laying, and acupuncture. The equipment investment is expensive, the production process conditions are high, and the energy consumption is large. The output is low, and the average thickness and weight of the fabric are difficult to control, which brings difficulties to the subsequent resin impregnation and dyeing deep processing. The thickness specifications of the produced fabrics are relatively limited. Generally, only 0.5-2.0mm medium thickness and no elastic specifications can be produced. Gray cloth, gray cloth with a thickness of less than 0.5mm and elastic specifications cannot be directly produced

In order to pursue gray fabrics with a specification below 0.5mm, some manufacturers adopt the process of first producing thickness above 1.2mm, and then adopting the process of cutting and slicing the fabric transversely. Significant decline, affecting subsequent applications
