Description

Ball for sports synthetic leather

Technical field

The technical program belongs to synthetic leather (artificial leather being namely commonly called as) technical field, specifically a kind of ball for sports synthetic leather.

Background technology

The production process of synthetic leather is usually, present base fabric is coated with foaming layer material, coated side layer material on foaming layer material again, it is then fed into baking oven (i.e. tunnel oven) to be heated, now, foaming layer foaming materials, constitute foaming layer, then through steps such as knurling rolls embossing etc., coolings, finally give synthetic leather. One class synthetic leather is material based on PVC, and foaming layer material and surface material etc. are based on PVC, and for foaming layer, its raw material, compared with surface material, with the addition of foaming agent.

The surface of basketball, football and vollyball etc. is coated with one layer of leather, becomes covering. In the past, the covering of high-grade ball was based on Corii Bovis seu Bubali. Due to the individual variation of Corii Bovis seu Bubali, so the parameters such as the frictional force on covering surface, tensile property are wayward, it is high that concordance controls cost. And the covering of synthetic leather class, it is possible to ensure concordance by modes such as surface layer, the formula of foaming layer material, technological parameters, and cost is not high. Limitation due to surface layer, foaming layer material itself, and the limitation of processing technique, the covering subject matter of current synthetic leather material is that poor flexibility, sense of touch are hard, frictional force is not enough compared with selected Corii Bovis seu Bubali material covering out (football after especially wet water).

Summary of the invention

In order to solve the above-mentioned problems in the prior art, the technical program conversion thinking, start with from structure, a kind of new ball for sports synthetic leather is proposed, it is surface layer, foaming layer and base fabric from top to bottom successively, it is characterized in that described base fabric includes upper, middle and lower-ranking, base fabric upper strata is identical with the structure of base fabric lower floor, and the center line about base fabric middle level is mirrored into symmetry;

For base fabric upper strata or base fabric lower floor: include warp thread and weft yarn, warp thread and weft yarns; The material of warp thread and weft yarn is to be prepared yarn by chinlon and spandex blending;

For base fabric middle level: be made up of the monofilament of terylene material;At same warp direction, there are two undaform monofilament, the wave-like difference half period of two monofilament;

The crest of arbitrary monofilament walks around the weft yarn on base fabric upper strata, and in adjacent two weft yarns, a weft yarn is enclosed in the crest of this monofilament and surrounds in space outside warp thread, and another root weft yarn is enclosed in outside crest and surrounds in space in warp thread;

The trough of arbitrary monofilament walks around the weft yarn of base fabric lower floor, and in adjacent two weft yarns, a weft yarn is enclosed in the trough of this monofilament and surrounds in space outside warp thread, and another root weft yarn is enclosed in outside trough and surrounds in space in warp thread.

For base fabric upper strata or base fabric lower floor: weft yarn becomes " S " type, adjacent even root weft yarns, constitutes netted.

Compared with prior art, this synthetic leather changes thinking, starts with from base fabric structure, by the three-decker of base fabric, supports upper and lower two-layer with terylene, makes base fabric have well elastic and toughness with foaming layer after coordinating. Mesh made by base fabric upper strata, the resilient yarn of lower floor's apparatus, by the retractility of mesh-structured retractility and yarn itself, makes synthetic leather have excellent handle.

This synthetic leather simple in construction, is suitable to produce.

Fig. 1 is the structural representation of this synthetic leather;

Fig. 2 is longitudinal tangent plane structural representation of base fabric;

Fig. 3 is base fabric schematic top plan view;

In figure: surface layer 1, foaming layer 2, base fabric 3, weft yarn 4, warp thread 5, monofilament 6.

Detailed description of the invention

Such as Fig. 1, a kind of new ball for sports synthetic leather, it is surface layer, foaming layer and base fabric from top to bottom successively;

As Fig. 2,3, described base fabric includes upper, middle and lower-ranking, and base fabric upper strata is identical with the structure of base fabric lower floor, and the center line about base fabric middle level is mirrored into symmetry;

For base fabric upper strata or base fabric lower floor: include warp thread and weft yarn, warp thread and weft yarns; The material of warp thread and weft yarn is to be prepared yarn by chinlon and spandex blending;

For base fabric middle level: be made up of the monofilament of terylene material; At same warp direction, there are two undaform monofilament, the wave-like difference half period of two monofilament;

The crest of arbitrary monofilament walks around the weft yarn on base fabric upper strata, and in adjacent two weft yarns, a weft yarn is enclosed in the crest of this monofilament and surrounds in space outside warp thread, and another root weft yarn is enclosed in outside crest and surrounds in space in warp thread;

The trough of arbitrary monofilament walks around the weft yarn of base fabric lower floor, and in adjacent two weft yarns, a weft yarn is enclosed in the trough of this monofilament and surrounds in space outside warp thread, and another root weft yarn is enclosed in outside trough and surrounds in space in warp thread.

For base fabric upper strata or base fabric lower floor: weft yarn becomes " S " type, adjacent even root weft yarns, constitutes netted.
