Composite elastic non-woven fabric production device and method for processing elastic non-woven fabric

Abstract

The invention relates to a composite elastic nonwoven fabric production device and a method for processing elastic nonwoven fabric. The composite elastic nonwoven fabric production device comprises a tape casting unit and an elastic separator, wherein the elastic separator comprises guiding rollers, elastic separating rollers, traction rollers, cutting rollers and winding rollers, and the elastic separating rollers comprise a pair of longitudinal strip-shaped separating rollers and a pair of mill pinions. The method for processing the elastic nonwoven fabric by the composite elastic nonwoven fabric production device comprises steps as follows: (1), materials are prepared; (2), the materials in the step (1) are mixed and stirred in a mixing agitator and subjected to synchronous rolling compositing by calendering rollers and films of the calendering rollers, and composite nonwoven fabric is formed; (3), the composite nonwoven fabric obtained in the step (2) is separated by the elastic separator, elastic strip-shaped nonwoven fabric is obtained and separated again, and blocky nonwoven fabric is obtained; (4), the blocky nonwoven fabric is cut. The elastic nonwoven fabric is composited without glue, so that harm of hazardous substances in the glue to a human body is avoided; the composite elastic nonwoven fabric has separation areas longitudinally and horizontally, thereby having elasticity in the longitudinal and horizontal directions.

Description

technical field [0001] The invention relates to a non-woven fabric and a processing method, in particular to a production device for a composite elastic non-woven fabric and a method for processing the elastic non-woven fabric. Background technique [0002] Non-woven fabrics are used in many aspects due to their soft, breathable and good feel, but the traditional non-woven fabrics have limited their use due to their lack of elasticity; although elastic non-woven fabrics are also available, due to the elastic rubber band installed inside, non-woven fabrics Relying on rubber bands to shrink and wrinkle, the overall thickness of the cloth surface is large, the amount of raw materials is large, and the cost is high. Due to the large thickness and heavy weight, it cannot meet the needs of exquisite products; there are also non-woven fabrics that can only be stretched horizontally and elastically, but not in multiple directions. Elastic stretching reduces market demand; no multi-d...

Problems solved by technology

[0002] Non-woven fabrics are used in many aspects due to their soft, breathable and good feel, but the traditional non-woven fabrics have limited their use due to their lack of elasticity; although elastic non-woven fabrics are also available, due to the elastic rubber band installed inside, non-woven fabrics Relying on rubber bands to shrink and wrinkle, the overall thickness of the cloth surface is large, the amount of raw materials is large, and the cost is high. Due to the large thickness and heavy weight, it cannot meet the needs of exquisite products; there are also non-woven fabrics that can only be stretched horizontally and elastically, but not in multiple directions. Elastic stretching reduces market demand; no multi-directional stretchable non-woven fabric equipment produced by elastic plastic film has been found so far, so a composite elastic non-woven fabric production device and processing with this device have been studied. The processing of elastic nonwovens is very necessary
