Problems solved by technology

However, since it is still extremely easy to adhere to pollutants, and not only the slip resistance is significantly reduced due to the adhesion of pollutants, but also it is not a structure with excellent surface strength such as abrasion resistance, so when considering its use as a ball covering material, it is still Does not address durability issues

Embodiment 1

[0070] The island component is 6-nylon, and the sea component is high-fluidity low-density polyethylene (sea component / island component = 50 / 50), and the two are melt-spun to form sea-island mixed spinning fibers. The obtained fibers were stretched, crimped and sheared to obtain short fibers with a fineness of 3.5 denier and a cut length of 51 mm. The short fibers are combed to form a web by cross-capping. Thereafter, use a felting needle with a hook attached to one part of the needle, at 980P / cm 2 Acupuncture with a needle punching density of 450g / m2 2 of non-woven fabrics. The non-woven fabric is heated and dried, and after the surface is smoothed by extrusion, it is immersed in a solution of 16% polyether polyurethane dimethylformamide (abbreviated as DMF), and coagulated with an aqueous solution of DMF. Wash with hot water, and use hot toluene to extract and remove the polyethylene in the fiber to obtain an artificial leather-like fiber substrate formed of 6-nylon ultra...

Embodiment 2

[0085] On the surface of the artificial leather-like fibrous base material produced in this embodiment 1 with 400g / m 2 A DMF solution of polyether polyurethane (manufactured by Dainippon Ink Chemicals Co., Ltd., MP-105) with a solid content of 20% was applied and solidified in water to form a high molecular polymer layer as a porous surface layer. Carry out coloring with the ether type polyurethane ink that comprises brown pigment on it, use the embossing roller of basketball that area of ​​convex part is bigger than embodiment 1, be that temperature is 180 ℃, pressure is 8kg / cm, processing speed is 1.2m / Under the condition of 1 minute, mold pressing is carried out to form a primary convex part, wherein the average height difference (A) of the circular primary convex part with a diameter of 3.8 mm is 170 microns, and the projected area on it is 11.1 mm 2 , the total projected area of ​​the protrusions was 48% of the total area of ​​the substrate sheet. Only the upper surface...

Abstract

A sheet material having polymer layer over the surface of base fabric, the polymer layer comprises a primary outwardly projecting pebbles and a secondary pebbles & valleys over the primary outwardly projecting pebbles, wherein an average height difference (A) of the primary pebbles is 50 to 1000 mum, a projected area of the upper surface of the primary pebbles is 1 to 300 mm<2>, an average height difference (B) of the secondary pebbles & valleys is 5 to 200 mum, an average distance between the pebbles each other of the secondary pebbles & valleys is 100 to 500 mum, and A>=B. A gas filling type ball, a basketball and a glove using the sheet material.

Description

technical field [0001] The present invention relates to a flap, a gas-filled ball covered by the flap, and a handbag. The present invention relates in more detail to a sheet having sufficient surface abrasion strength and excellent slip resistance obtained by forming secondary convex and concave portions on the primary convex portion, and to a basketball covered by the sheet Such as gas-filled balls, handbags formed from the sheet. Background technique [0002] As surface materials for gas-filled balls, especially gas-filled sports balls, many proposals have been made so far in which leather-like sheets are used instead of natural leather. Especially in the case of balls used in sports where the ball is touched by hand, the material used to cover the ball is required to have non-slip properties in many cases, so various techniques for imparting non-slip properties to leather-like sheets have been proposed. [0003] For example, in various materials including artificial lea...
