Problems solved by technology

[0004] In the prior art, the basketball leather is mainly embossed and granulated on the surface of the synthetic leather to improve the touch of the synthetic leather. Reduced slip performance
"Astringent Finishing Agents for Basketball Leather" uses hydrophilic PU resin, polypropylene micropowder, silk peptide powder, etc. as leather astringent finishing agents, but the adhesion and hygroscopicity to basketball leather are still not ideal

Embodiment 1

[0034] Embodiment 1: a kind of basketball leather, comprise base cloth layer, it is characterized in that: comprise microfiber base cloth layer, bonding layer, waterborne polyurethane elastomer foaming layer and polyurethane surface layer, be provided with anti-skid reinforcement on surface layer Astringent film. The superfine fiber base cloth layer is a fabric web formed on a mesh conveyor after the sea-island fibers formed by nylon 6 and polyethylene are opened, and then the fabric web is heated to 100°C by a pair of upper and lower rolling. The textured roller is thermally bonded, and then interlaced by needle punching, dipped in water, lightly rolled by a rolling mill, and then peeled and divided by a percussion kneading machine to obtain a weight per unit area of ​​210g / m 2 The ultrafine fiber non-woven fabric, and then shrink the nonwoven fabric in warm water at 70°C to obtain an ultrafine fiber base fabric with an area of ​​60% of the area before shrinkage, and its unit...

Abstract

The invention relates to basketball leather. The basketball leather comprises a superfine fiber base cloth layer, an adhesion layer, an aqueous polyurethane elastomer foaming layer and a polyurethane surface layer, wherein a non-slip astringent film layer is arranged on the surface layer.

Description

[0001] This application is a divisional application of the invention patent application with the application number 2014103166668, the invention title is "a basketball leather", and the application date is 2014-07-06. technical field [0002] The invention relates to a basketball leather. Background technique [0003] In recent years, the application field of synthetic leather has been continuously developed. However, to produce ideal basketball leather, it must be plump and elastic, and its mechanical strength, chemical resistance, moisture absorption and perspiration, weight uniformity, and anti-slip properties can all be achieved. Requirements, which have high requirements for the elastomer forming basketball leather. As basketball leather, it is especially required to have a wet touch. The basketball made in this way is easy to grasp, even if the athlete produces a lot of hand sweat due to strenuous exercise, he can still grasp the basketball. [0004] In the prior art,...
