Problems solved by technology

All microfiber fabrics generally have the highest purpose of achieving high imitation leather. The fixed-island type super-fabric adopts alkali reduction fiber opening, which is safer and more environmentally friendly than the indeterminate island-type superfiber fabric using toluene. At present, it still needs to be impregnated with polyvinyl alcohol PVA and oily polyurethane (containing dimethylformamide DMF), which needs to add organic solvents such as DMF, which has a great impact on the environment during the production process, and the treatment of DMF residues will increase the processing time. cost

Abstract

The invention relates to a green microfiber fabric and a manufacture process thereof, and belongs to the technical field of top-grade textile fabric. The green microfiber fabric consists of 37-island figured sea-island staple fiber and water-base resin, wherein the 37-island figured sea-island staple fiber accounts for 50 to 80 percent by weight, and the rest is the water-base resin; or the green microfiber fabric consists of 64-island figured sea-island staple fiber and water-base resin, wherein the 64-island figured sea-island staple fiber accounts for 65 to 80 percent by weight, and the rest is water-base resin. The manufacture process does not use polyvinyl alcohol (PVA) and dimethylformamide (DMF) and has characteristics of no toxic substance residue; moreover, a great amount of water is saved, the energy consumption is controllable, the produced green microfiber fabric is excellent in real-leather feeling, high in color fastness, and the physical performance of the produced green microfiber fabric is better than that of the real leather.

Description

technical field [0001] The invention relates to a green superfiber 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 generally have the highest purpose of achieving high imitation leather. The fixed-island type super-fabric adopts alkali reduction fiber opening, which is safe...
