Double-die-head compound interlaced two-component spunbond spunlace non-woven fabric production equipment and production process

Abstract

The invention relates to the technical field of non-woven fabric manufacturing equipment and particularly relates to double-die-head compound interlaced two-component spunbond spunlace non-woven fabric production equipment and a production process. The equipment comprises a lapping machine, wherein a tube type stretching mechanism and a long-slit stretching mechanism are arranged on the lapping machine; the tube type stretching mechanism comprises a melt spinning small-component compound die head, a unidirectional lateral blowing device, a drafting head, a stainless steel drafting tube, a sway machine and a guiding device in sequence from top to bottom; the long-slit stretching mechanism comprises a melt spinning big-component compound die head, a bi-directional lateral blowing device and a long-slit negative pressure stretching device. A product prepared by the production equipment and the production process has the advantages that the uniformity and the strength of a cloth cover are enhanced, the fiber strength is 100g / m<2> as fixed weight, the longitudinal breaking strength is 380N / 50mm, the horizontal breaking strength is 260N / 50mm, the longitudinal stretching rate is 78%, the longitudinal tearing strength is 60N, the horizontal tearing strength is 40N, and the CV (coefficient of variation) value of the uniformity of the product is 3-5%.

Description

technical field [0001] The invention relates to the technical field of non-woven fabric manufacturing equipment, in particular to the production equipment and production process of double-die compound interlacing two-component spunbond spunlace non-woven fabric. Background technique [0002] In the field of chemical fiber filament production, the two-component composite spinning technology is relatively mature and has been widely used. There are many types of fiber cross-sectional shapes of various filaments, and fabrics prepared from filaments prepared by spinning POY+DTY\FDY process routes have been widely used in the field of clothing. The fiber drawing process in the spinning long fiber process includes hot rolling drawing, tubular HOY drawing method, spinning and winding into rolls and then weaving process. In the process mode of spunbonded nonwoven fabric production equipment, tubular stretching and long slit stretching are independently completed on the laminating ma...

AI Technical Summary

Problems solved by technology

When the drafting wind pressure is 0.5MPa in the tubular drawing method, the vertical and horizontal strength of the fiber filament and the finished cloth can generally reach 1:1.0~1.2, but the deviation of the uniformity is generally ≥7%, which affects the market of the product application, especially two-component thin 50g / m 2 The left and right spunbonded spunlace fabrics cannot be used to prepare leather base fabrics and filter materials
