Elastic fabric manufacturing method and elastic cloth thereof

Abstract

The invention relates to a manufacture method for flexible-wave or drum paper sutural margin molding elastic woven material for loudspeaker or microphone. It includes the following steps: mixing flexible fiber, cotton, polyester fiber, and acrylic fiber according to certain ratio, drawing out suitable flexibility thread to weave flexible cloth; or drawing out suitable flexibility thread from flexible fiber, cotton, polyester fiber and acrylic fiber material, weaving certain flexibility cloth according to suitable ratio; or weaving suitable flexibility thread from thread of different material and weaving flexibility cloth.

Description

technical field [0001] The present invention relates to a kind of manufacturing method of elastic cloth and the elastic cloth made by it, especially relate to the manufacturing method and the Elastic cloth made from it. Background technique [0002] The spring wave or drum paper joint is one of the most important components in the horn or speaker structure. The spring wave or drum paper joint with better elastic expansion and toughness characteristics can provide better output power and audio frequency of the horn or speaker. It is also the basis for speaker or speaker manufacturers to manage quality when manufacturing speakers or speakers. In addition, the elastic wave also has the effect of maintaining and extending the service life of the horn or loudspeaker. [0003] The traditional forming wave or drum paper joint edge is based on cotton cloth, which is dipped in liquid synthetic resin to make the fibers of the cotton cloth absorb the synthetic resin, and the cotton c...

AI Technical Summary

Problems solved by technology

[0005] (1) The elastic wave or drum paper joint edge made of cotton cloth has poor lateral force resistance, and is prone to fatigue and rupture, resulting in damage to the sound of the elastic wave or drum paper joint edge, and its service life is not long

[0006] (2) The elastic wave or drum paper joint edge made of cotton cloth lacks elastic stretching force, the resonance flexibility with the sound wave is not good, and the sound quality is also poor.

[0007] (3) The elastic wave or drum paper joint edge made of cotton cloth has poor toughness and strength, and it is also poor to withstand the sound wave pressure of high-power output, so it is impossible to make a high-output shaped elastic wave or drum paper joint edge.

[0009] (1) The thin steel wires in the weaving of cotton cloth cause great damage to the forming and cutting mold of the elastic wave. The elastic wave forming and cutting mold is used to cut off the edge of the mold for forming elastic waves. After a period of time, the cutting mold cannot cut off the forming elastic wave, and the cutting mold must be replaced. Therefore, in addition to interrupting production and causing waste of time, the cost of the mold will also be increased, and the manufacturing cost will also increase.

[0010] (2) The elasticity and toughness of thin steel wire are much higher than that of cotton fiber, which will cause uneven local stress and form the interference phenomenon of sound wave resonance
