Preparation method of composite non-woven fabric

Abstract

The invention discloses a preparation method of a composite non-woven fabric. The composite non-woven fabric is composed of a superfine fiber layer, a polyester fiber layer and two layers of non-woven fabric base materials; the preparation method is implemented through the following steps of S1, a first double-screw film blowing machine is heated to 260-265 DEG C, and polyester fibers are put into the first double-screw film blowing machine for extrusion and mixing; S2, the non-woven fabric base materials are pulled, tensioned and flatly laid on a first processing platform, pure water at the temperature of 55-60 DEG C is sprayed to the non-woven fabric base materials, the pure water is sprayed to the non-woven fabric base materials through double die heads of the first double-screw film blowing machine to form a net, and then the net is pulled into a rolling mill to be subjected to rolling and hot sticking to form a fabric; S3, a second double-screw film blowing machine is heated to 250-255 DEG C, and the superfine fibers are put into the first double-screw film blowing machine to be extruded and mixed; S4, the first composite fabric is pulled to cover the top face of the non-woven fabric base materials after net forming, the first composite fabric is connected with the non-woven fabric base materials in a bonding mode through 200 DEG C hot pressing, then the bonded product is pulled into the rolling mill to be subjected to rolling and hot sticking to form the fabric , and the composite fabric is obtained; and S5, the composite fabric obtained in the step S4 is pulled to a hot air drying furnace for drying.

Description

technical field [0001] The invention belongs to the technical field of nonwoven fabrics, and in particular relates to a preparation method of composite nonwoven fabrics. Background technique [0002] Non-woven fabrics have the characteristics of moisture-proof, breathable, light weight, and easy to decompose. They are widely used in clothing, cleaning, medical care, agriculture and other fields. Non-woven fabrics are generally formed by orienting or randomly arranging short textile fibers or filaments The network structure is formed by reinforcement through mechanical, thermal bonding, chemical adhesion and other methods. However, with the application of non-woven fabrics in more scenarios, the application performance of non-woven fabrics needs to be improved. Currently, the market Most of the non-woven fabric products with enhanced performance are formed by composite multi-layer structure, but each non-woven fabric product with different performance has different production...

Problems solved by technology

There is a non-woven fabric with high water absorption, which is composed of non-woven fabric and superfine fiber and polyester fiber compositely filled between the non-woven fabrics. In the existing technology, each layer is usually stacked and then planned. The edge of the grid is sealed, and then cut according to the planned grid edge. The operation of the process is simple but the cost is relatively high, but the non-woven fabric prepared by this method is poor in durability and easy to be damaged. Based on this, there are It is necessary to develop an improved preparation method
