Embodiment Construction

[0059] The present invention will be further elaborated below in conjunction with the accompanying drawings.

[0060] Such as figure 1 , figure 2 with image 3 As shown, PET and PA-6 slices are delivered to respective dryer 1 and dryer 2, and after drying, they are sent to screw extruder 1 and screw extruder 2 for melting, and the obtained melt is filtered and measured by filter 5 and filter 6 , PA-6 first enters the sub-box 8, and then the melt pipe of the sub-box 8 is introduced into the main box 10 and the main box 9, and PET directly enters the main box 10 and the main box 9, or according to The production requirements first enter the auxiliary box 7, and then enter the main box 10 and the main box 9; after the melt is compounded by the spinning assembly, it is sprayed out from the spinneret hole, and the sprayed melt flows through the side wind air-cooled The device 11 and the air cooler 12 are rapidly cooled into as-spun yarns, the conjugate compounding temperature i...

Abstract

The invention belongs to the technical field of spun-bonded nonwovens manufacturing. The manufacturing method comprises the following steps: a. respectively drying, extruding, melting and filtering the two slices made of different materials according to a ratio; b. precisely measuring the two melts with a metric pump to enter into a main box for conjugate composition, spinning the composite melts at the condition of air cooling to obtain hollow as-spun fibers; c. air-drafting and spinning the as-spun fibers; d. spreading and lapping the obtained spinning; e. carrying out spunlace solidifying and splitting on the fiber nets obtained by spreading and lapping; and f. drying and shaping to form clothes. The device comprises a slice device, a conjugate composition device, a spinning device, an air drafting device, a swaying yarn and web forming device, a spunlace device and a sari forming device which are arranged in turn, and also comprises a central control desk which can manipulate the devices. The invention has the advantages of less labor room buildings, short processing flow, high production efficiency and the like. And the produced non-woven fabrics have better hand feeling, better softness and thinner single fiber fineness, have improved filtering property and developed application of the non-woven fabrics in health care.

Description

technical field [0001] The invention belongs to the technical field of spunbond nonwoven fabric manufacturing, in particular to a manufacturing method and equipment for a two-component hollow spunbonded spunlace nonwoven fabric. Background technique [0002] Ultrafine composite fibers are widely used due to their advantages of high coverage, softness and comfort, good adsorption, and fine cloth surface. There are many technical routes for applying ultrafine composite fibers to the field of nonwovens manufacturing technology. Divided into skin-core type, side-by-side type, sea-island type and orange segment type, the commercially available products are mainly sea-island type and orange segment type. [0003] The sea-island type can be divided into two types: fixed island type and indeterminate island type. The two component slices are conjugated, melt-spun, cooled, and drawn to make sea-island short fibers, and then carded into a web and needle-punched to make a non-woven bas...
