specific Embodiment approach 1

[0012] Embodiment 1 of the present invention, the cotton fiber and the polyester fiber are uniformly mixed in a ratio of 50%: 50% by weight; the mixed fibers in the previous step are then spun into threads; and finally the threads formed in the previous step are woven into cloth . The elastic fabric can be made by gluing the formed elastic cloth and then creasing it. The production process, spinning process, and weaving process of the above-mentioned cotton fibers and polyester fibers are in the prior art, and will not be described in detail here. The ratio of cotton fiber to polyester fiber in this embodiment is the optimum ratio.

specific Embodiment approach 2

[0013] In the second embodiment of the present invention, cotton fibers and polyester fibers are spun into cotton threads and polyester fiber threads, respectively; and then the cotton threads and polyester fiber threads formed in the previous step are mixed and kneaded at a ratio of 45%: 55% by weight. Hybrid thread; finally weave the hybrid thread formed in the previous step into a cloth. The elastic fabric can be made by gluing the formed elastic cloth and then creasing it. The production process, spinning process, and weaving process of the above-mentioned cotton fibers and polyester fibers are in the prior art, and will not be described in detail here.

specific Embodiment approach 3

[0014] In the third embodiment of the present invention, cotton fibers and polyester fibers are uniformly mixed in a ratio of 55%: 45% by weight; the mixed fibers in the previous step are then spun into threads; and finally the threads formed in the previous step are woven into cloth . The elastic fabric can be made by gluing the formed elastic cloth and then creasing it. The production process, spinning process, and weaving process of the above-mentioned cotton fibers and polyester fibers are in the prior art, and will not be described in detail here.

Abstract

The invention relates to elastic fabric used for loudspeaker elastic wave. The invention comprises the following components by the weight percentages as follows: cotton fiber is 42% to 58% and polyester fiber 58% to 42%. The content of the cotton fiber and the polyester fiber in the invention is moderate; utilizing the good adhesiveness of the cotton and the good strength of the polyester fiber not only ensures that the elastic fabric has enough adhesiveness to bond and shape with glue water, but also guarantees that the elastic fabric has enough strength so that the fabric is not likely to be torn up during the process of press-pleating and shaping, thus optimizing the comprehensive performance of the elastic fabric.

Description

technical field [0001] The present invention relates to a horn-bounce material, in particular to an elastic cloth used for horn-bounce. Background technique [0002] The elastic wave of the horn is also called the positioning support, which is usually made of cotton fiber woven into a cloth, and then glued or dipped into the fabric and formed by creasing. Cotton cloth has the advantage of good adhesion and can be well combined with glue. However, the disadvantage of the elastic wave made of cotton is that it has poor tensile properties and is very easy to be torn during the pleating process. [0003] In order to overcome the above shortcomings of pure cotton fiber elastic wave, some manufacturers use the method of mixing polyester fiber into pure cotton fiber to improve the strength, but the content of polyester fiber usually used is very small, which cannot achieve the purpose of improving strength well. . Chinese patent 02134429.9 discloses a "vibration piece", the mate...
