Non-woven cambric and production thereof

Abstract

A non-woven bast cloth for the inner surface of car top and the liner of artificial leather used for car, or as polishing material for steel, copper, or aluminium is prepared from bast fibres through airflow netting, immersing and adhering. Its advantages are high tension strength and temp stability, good moisture and air permeability, and high heat insulation.

Description

Technical field: [0001] The invention relates to a non-woven linen and a production method thereof. It is mainly used as the inner lining material of the car roof and the artificial leather bottom surface material of the car. It can also be used as finishing polishing material for steel, copper and aluminum. It belongs to the technical field of nonwoven fabrics. Background technique: [0002] Existing non-woven fabrics generally all adopt chemical fiber production. Existing automotive interior lining materials are generally made of glass fiber mesh sheets of glass fiber mesh profiles and chemical fiber hot-rolled non-woven fabrics. The construction process is: chemical fiber non-woven fabric-glue-glass fiber mesh cloth-sponge-glue, reaching a certain thickness for composite heat drying and shaping, cutting into pieces, and performing hot-melt molding according to the size of the vehicle model—— Cut - finished product. Its disadvantages are: [0003] 1. The shape of the...

AI Technical Summary

Problems solved by technology

[0003] 1. The shape of the glass fiber mesh itself is poorly fixed, and it is easy to crepe when the cloth is withdrawn from the cloth, the speed difference is uneven, the tension is uneven, and the cloth surface is unevenly distributed;

[0004] 2. Polyester fiber has unstable cold and heat resistance, poor wear resistance, moisture absorption, air permeability and moisture permeability

[0005] 3. Poor adhesion between glass fiber mesh and glue;

[0006] 4. Dust generated by high-speed shearing during construction is harmful to the human body and seriously affects the working environment of workers

[0009] 2. The wear resistance of cotton fiber is poor;

[0010] 3. The cost of finishing cotton fiber through spinning and weaving is high;

[0011] 4. Chemical fibers contact with objects through high-speed operation during polishing, which is easy to generate heat, and high-temperature melting will cause agglomeration, which will affect the polishing quality
