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

[0036] Example 1: A basketball leather including a base fabric layer, characterized in that it includes a superfine fiber base fabric layer, an adhesive layer, a water-based polyurethane elastomer foam layer and a polyurethane surface layer, on which an anti-slip and astringent film is provided Floor. The superfine fiber base fabric layer is a fabric net formed on a mesh conveyor after opening sea-island fibers formed of nylon 6 and polyethylene. Then, the fabric net is heated to 100° C. The grain roll is thermally bonded, and then interlaced by needle punching, then immersed in water, lightly rolled with a rolling mill, and then peeled and divided with a percussion kneader to obtain a basis weight of 210g / m 2 The ultra-fine fiber nonwoven fabric is then shrunk 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 area weight is 350g / m 2 , The thickness is 1.0mm, and the fineness is 0.15dtex.

Abstract

The invention discloses basketball leather. The basket leather comprises an ultrafine fiber base cloth layer, a binding layer, a waterborne polyurethane elastomer foaming layer and a polyurethane surface layer, wherein the surface layer is provided with a non-slip unsmooth-increasing film. Since the surface layer is provided with the non-slip unsmooth-increasing film, the unsmooth feeling on the surface of the basketball is improved.

Description

[0001] 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, the basketball leather is mainly embossed and granulated on the surface of the synthetic leather to improve the touch of the synthetic leather. Anti-slip performance is reduced. "Astringent Finishing Agents f...
