Problems solved by technology

However, when it is used for the bottom film of composite breathable film, the conventional PP spunbonded non-woven composite bottom film needs to be bonded with glue, and additional adhesive materials need to be added, and the adhesion is very poor.

Embodiment 1

[0032] Example 1, PE raw material LL6101XR, elastomer Vistamaxx 6020FL are mixed according to the ratio of 98%: 2%

[0033] Preparation method of PE spunbond nonwoven fabric:

[0034] 1. Mix PE raw material LL6101XR and elastomer Vistamaxx 6020FL according to the ratio of 98%:2%;

[0035] 2. The mixed and stirred raw materials are extruded and melted to the screw through the feeding system (vacuum suction) to obtain a hot melt (screw melting temperature 270°C);

[0036] 3. Filter, measure and distribute the hot melt at a certain temperature and pressure (the operating temperature for filtering, measuring and distributing the hot melt is 250°C and the pressure is 10MPa);

[0037] 4. Spinning the distributed and metered hot melt, and cooling the spun silk through the side cold air to obtain primary growth filaments (the distributed and metered hot melt is spun out through a 0.8mm aperture) The silk is cooled by a cooling bellows, the temperature of the cooling bellows is 20°C,...

Abstract

The invention relates to a PE spun-bonded non-woven fabric which is composed of PE raw material and elastomer mixed at a ratio of 98%: 2%. The elastomer is VISTAMAXX 6020FL, and the PE raw material isLL6101XR. A manufacturing method of the PE spun-bonded non-woven fabric is further disclosed. A bottom film product for composite air permeable films is produced by using the PE raw material insteadof the conventional PP raw material. The composite bottom film of the conventional PP spun-bonded non-woven fabric needs to be bonded by adhesive. The novel PE spun-bonded non-woven fabric has good adhesion, and can be directly composited with an air permeable film after heating without adding adhesive materials. On the other hand, the PE spun-bonded non-woven fabric can be used in wallpaper without gluing.

Description

technical field [0001] The invention belongs to the technical field of spun-bonded non-woven fabrics, and in particular relates to a PE spun-bonded non-woven fabric and a manufacturing method thereof. Background technique [0002] Non-woven fabric is a kind of non-woven fabric formed by directly using polymer chips, short fibers or filaments to form fibers through airflow or mechanically, and then undergo spunlace, needle punching, or hot rolling reinforcement, and finally finish finishing. . Compared with traditional textile fabrics, it has the characteristics of short process flow, fast production speed, high output, low cost and wide application. It is widely used in medical and health care, home decoration, automobile industry, clothing accessories and other fields. With the improvement of people's living standards and the enhancement of safety awareness, the flame retardancy of non-woven fabrics has increasingly become the focus of attention. [0003] Spun-bonded non...
