Problems solved by technology

[0004] Due to the use of pure polyethylene powder particles when dusting, although the mesh number of powder dusting can be manually adjusted, after the polyethylene powder particles melt, it is easy to form a layer of film, and the skin non-woven fabric is bonded to the lower non-woven fabric. After spinning, the gaps between polyethylene powders are relatively small, and the air permeability of non-woven fabrics is relatively poor

Embodiment 1

[0036] Example 1: A highly air-permeable non-woven fabric, which includes an upper non-woven fabric, an adhesive layer, and a lower non-woven fabric from top to bottom. The lower layer of non-woven fabric is ordinary gray cloth, and the adhesive layer is formed by melting the adhesive, which is made of PE and CaCO 3 Composition, and the weight ratio of PE is 50%-90%, CaCO 3 The weight ratio is 10%-50%, the mesh number of the adhesive is 10-100 mesh, and the gap between the adhesives after composite molding is 150-1700 microns, so that the gap can be ensured to be large enough, thereby improving the composite without The breathability of the fabric.

Embodiment 2

[0037] Embodiment two: a kind of production process that is used to produce the highly air-permeable non-woven fabric in embodiment one, specific production process is as follows:

[0038] S1. The lower non-woven fabric is conveyed forward at a speed of 2m / min-10m / min and passes through the powder spreading device. The powder spreading device here is a common powder spreading machine in the industry, and the lower non-woven fabric is driven forward by rollers. Send through the powder spreader; S2, the powder spreader evenly sprinkles the adhesive powder on the lower layer of non-woven fabric, and conveys it forward through the oven, and the mesh number of the powder here is 10-100 mesh; S3, the temperature of the oven Keep it at 100°C-400°C, and melt the adhesive powder, attach the upper layer of non-woven fabric to the surface of the lower layer of non-woven fabric sent out from the outlet of the drying room and bond it; S4, for the bonded non-woven fabric The woven fabric is...

Abstract

The invention discloses a highly air-permeable non-woven fabric and a production process for producing the non-woven fabric, aiming at solving the problem of poor air-permeability of the non-woven fabric. : From top to bottom, it includes an upper layer of non-woven fabric, an adhesive layer and a lower layer of non-woven fabric, the adhesive layer includes an adhesive, and the adhesive includes PE and CaCO 3 , and the weight ratio of the PE is 50%-90%, CaCO 3 The weight ratio is 10%-50%, and the binder is 10-100 mesh. The non-woven fabric with high air permeability and the production process for producing the non-woven fabric of the present invention make the produced non-woven fabric have the advantage of high air permeability.

Description

technical field [0001] The invention relates to the field of non-woven fabric production and processing, more specifically, it relates to a highly air-permeable non-woven fabric and a production process for producing the non-woven fabric. Background technique [0002] In the field of non-woven fabric production, the existing two-layer and three-layer composite process processing methods of non-woven fabrics of rolls and sheets include the method of bonding two layers of non-woven fabrics through adhesive materials. [0003] For example, the Chinese patent whose publication number is CN103640308A discloses the processing technology of non-woven fabric composite materials for automobile interior decoration, which first sprinkles polyethylene powder particles on the lower layer of non-woven fabric, and then attaches the lower layer of non-woven fabric with polyethylene powder particles. The cloth is sent into the oven to melt the polyethylene powder particles, and then the skin...
