Abstract
The invention relates to a preparation method of a basketball containing fabric, which comprises the steps of (1) weaving a three-dimensional nylon plain weave: during weaving, the weaving area of the three-dimensional nylon plain weave adopts a double-layer weaving process, and when forming each weave point, a Determine the corresponding heddle eye height and let-off amount in the weaving area of the three-dimensional nylon plain weave to obtain a three-dimensional nylon plain weave; place a grid-like support with the same hemispherical surface in the area from the corresponding weaving fell to the first row of healds Under the condition of constant tension, each warp yarn is actively let off independently; (2) three-dimensional nylon plain weave is made into basketball fabric; (3) basketball fabric is made into basketball with basketball fabric as protective layer inner tank; (4) making a basketball; the method in the present invention can realize the interweaving of warp and weft yarns on the curved surface by controlling the warp let-off amount and the lifting stroke, and can prepare basketball fabrics with equal warp and weft densities; The basketball is not deformed or bulged during use, which prolongs the service life of the basketball.
Description
technical field [0001] The invention belongs to the technical field of sports equipment and relates to a preparation method of a basketball with fabric. Background technique [0002] Basketball is a kind of sport in which teams compete against each other in the same field. Because of its low activity restrictions, small space occupied, and low equipment costs, it is loved and accepted by a wide range of sports enthusiasts. When manufacturing a basketball, a basketball-specific nylon yarn must be evenly wound on the surface of the inner tank of the ball to form a protective layer like a cocoon on the bladder. The main function of the yarn winding is to prevent the deformation of the basketball, which is similar to shaping The general yarn winding process is to use a sophisticated special basketball winding machine to evenly wind the basketball liner on the basketball liner. After winding, a layer of glue will be brushed on the yarn to shape the yarn and can be well integrated...
