Abstract
The present invention belongs to the field of synthetic leather product and its production. The fascicular superfine fiber polyurethane synthetic leather for sofa is produced with fascicular superfine fiber base cloth and through facing and serial post-treatment, and features its fiber structure similar to that of collagenous fiber in natural leather. The fiber structure is formed with fascicular superfine fiber skeleton in 3D structure and through filling with polyurethane with excellent performance and open celled structure and further processing. The product of the present invention is superior to available polyurethane and PVC synthetic leather in clear pattern, fullness, flexibility, peeling strength, wear resistance, etc. and superior to natural leather in mechanical strength, chemical resistance, quality homogeneity, etc.
Description
One, technical field
The present invention relates to a kind of Bundle-like ultrafine fibre polyurethane sofa leather and its production method, belong to synthetic leather product and production technology field.Be applicable to daily daily necessitiess such as making high-grade sofa, case and bag, auto use chair.
Two, background technology
The synthetic leather of bundle superfine fibre polyurethane is as a kind of high emulated artificial leather, and its fiber can reach below 0.01 DENIER, and the fiber number of fiber and structure are extremely similar to the collagenous fibres of natural leather.According to the serviceability of bundle superfine fibre, all kinds of fields such as shoemaking, case and bag, system ball, clothes bundle superfine fibre have been applied to.But with leather, but captured by natural leather and PVC artificial leather for a long time as the domestic family property of another big Application Areas of bundle superfine fibre always.
Three, summary of the invention
The bundle superfine fibre series products has light weight, soft, characteristic such as stretch, tear is better than natural leather, intensity is especially considerably beyond the PVC artificial leather, utilization rate on the measuring and calculating natural leather is in the private leather only is about 70%, the utilization rate of bundle superfine fibre artificial leather then can reach more than 90%, so, the success develop the bundle superfine fibre polyurethane sofa artificial leather will bring family property with the leather a revolution.
The object of the present invention is to provide a kind of bundle superfine fibre polyurethane sofa artificial leather with characteristic and advantage of natural leather, aspect the clear and natural of decorative pattern, aspect such as richness, flexibility, peel strength, anti-wear performance all is better than common polyurethane, PVC artificial leather, cut out aspects such as flexibility (adaptability) of operation in mechanical strength, chemical-resistance, quality homogeneity, shape-retaining ability, automation and more be better than natural leather.
The objective of the invention is to realize by following technical scheme:
The bundle superfine fibre polyurethane sofa artificial leather, be to be base cloth with the bundle superfine fibre, behind veneer, carry out the sofa artificial leather that a series of post processings form, collagenous fibres are extremely similar in the fibre structure that its special character is product and the natural leather, the three-dimensional structure that is employing bundle superfine fibre (filament number is below 0.01d) is a skeleton, the polyurethane with open-celled structure of filling capacity excellence is made through processed therein, and product is a kind of artificial leather material that exactly likes natural leather.
The manufacture method of bundle superfine fibre polyurethane sofa artificial leather, its special character is:
(1) will be with nylon (polyamide) and polyethylene weight ratio mixed melting with 35-65%:35-65%, through reeling off raw silk from cocoons, acupuncture, pressing, dipping polyurethane, solvent extracts out and makes the bundle superfine fibre base cloth;
(2) (1) bundle superfine fibre base cloth is carried out flour milling, employing thickness sand paper polishes the bundle superfine fibre base cloth respectively and fluffs, make the bundle superfine fibre base cloth be fit to veneer, and base cloth back side effect is extremely similar to natural leather, and dye, oiling treatment is carried out the expanding drying then, makes the dyeing base cloth;
(3) the dyeing base cloth of (2) item after oiling rubbed the leather machine with five sections and rub by force, pass through the polyurethane veneer then, make dyeing base cloth surface uniform color of formation and decorative pattern, make the semi-finished product sofa artificial leather with 2 meters speed;
(4) (3) semi-finished product sofa artificial leather was carried out water, segmentation drops in the boarding machine then, rubs line 20-40 minute under 40 ℃-60 ℃ condition, carries out post processing (filling, typing etc.) again, promptly makes bundle superfine fibre polyurethane sofa artificial leather of the present invention.
(1) the dipping polyurethane described in, solvent are extracted out to solidifying, the extraction of toluene adverse current, carry out the expanding drying make the bundle superfine fibre base cloth under 100-130 ℃ with 18% concentration hydrolysis resistant polyurethane dipping, the DMF aqueous solution in back that nonwoven fabric is plated;
(2) the bundle superfine fibre base cloth that the dyeing described in, oiling treatment are to use the dyestuff of mainly being made up of ACID DYES, DISPERSE DYES etc. will grind behind the skin dyes, and the bundle superfine fibre base cloth that has dyeed is oiled;
(3) the bundle superfine fibre base cloth surface lining described in is a polyurethane resin; Veneer is that surface layer adopts ABRASION RESISTANCE polyurethane, and adhesive layer adopts two liquid type polyurethane, wet combining;
(4) water of crossing described in is with bundle superfine fibre polyurethane sofa artificial leather semi-finished product immersion extruding, makes moisture about 10-20%.
Adopt above technical scheme of the present invention, its superiority is:
