Production equipment for spunbonding of filament double-component hot-air non-woven fabric

Abstract

The invention provides production equipment for spunbonding of filament double-component hot-air non-woven fabric. The production equipment comprises a fusing mechanism. A spinning unit has an inner layer and an outer layer; and the heating temperature of the fusing mechanism is larger than a softening temperature of the outer layer of the spinning unit and is less than a melting point of the outer layer of the spinning unit and the softening temperature of the inner layer of the spinning unit. Therefore, fully binding of the inner layer and the outer layer of the spinning unit can be guaranteed; a phenomenon that another fiber is fused when the inner layer or outer layer has not fused completely can be avoided; the influence on the physical and chemical properties of the fiber due to excessive fusing can be eliminated; and the physical and chemical properties of the fiber can be realized completely. After testing, compared with the existing product, the produced manufactured by the equipment has the structure and form that are close to those of a silk fiber batting piece; the strength property, wearing-resistant performance, and elasticity of the product are improved substantially; the anti-pilling property is good and firmness is high; the vertical pulling strength is larger than 18N and the horizontal pulling strength is larger than 8N; and the pilling degree reaches a seventh level under the friction force of 90 N.

Description

technical field [0001] The invention relates to a spunbonded nonwoven fabric, in particular to a production equipment for a spunbonded nonwoven fabric. Background technique [0002] In the chemical fiber field, composite spinning technology has been very mature and widely used. Due to the variety of cross-sectional structures of composite filaments, especially with the development of composite spinning technology, the spinning components and their processing technology are becoming more and more perfect, the cross-sectional composite shapes are ever-changing, and the most commonly used structural forms are divided into skin-core type. , side-by-side and peel-off three forms. [0003] With the development of composite fiber research and manufacturing technology and the gradual maturity of industrial applications, the two-component spunbond nonwoven fabric produced by combining composite spinning technology and spunbond nonwoven technology has gained more and more popularity ...

AI Technical Summary

Problems solved by technology

In the production process, it is necessary to use equipment such as a melting mechanism to melt the material, and then composite spinning to form a woven fabric; and the strength and wear resistance of the woven fabric produced by the existing technology are poor, mainly because the existing spinning The performance of the material itself and the control accuracy of the melting equipment for the melting temperature of the material are not high, and the physical and chemical properties of the main fiber cannot be fully utilized, resulting in poor product quality and small application range
