Abstract

The invention provides a high-strength and low-stretch non-woven fabric for car seats, comprising two layers of PET staple fiber needle-punched non-woven fabric layers, and the PET staple fiber needle-punched non-woven fabric layers are PET staple fiber needle-punched non-woven fabric layers respectively Woven fabric layer one and PET staple fiber needle-punched nonwoven fabric layer two, PET staple fiber spunbond nonwoven fabric layer between the PET staple fiber needle-punched nonwoven fabric layer one and PET staple fiber needle-punched nonwoven fabric layer two The cloth layer, the PET staple fiber needle-punched non-woven fabric layer one and the PET staple fiber needle-punched non-woven fabric layer two are short fiber layers formed by mixing L-PET and PET. The invention also provides its preparation method. The invention uses three layers of non-woven fabrics with different structures and different processes to combine long and short fibers, the fiber direction is disordered, there is no distinction between warp and weft, the difference in longitudinal and transverse tensile force and elongation of the product is small, and the tear strength is greatly improved.

Description

technical field [0001] The invention relates to a non-woven fabric and a manufacturing method thereof, in particular to a high-strength and low-stretch non-woven fabric for car seats and a manufacturing method thereof. Background technique [0002] With the rapid development of the economy, the continuous improvement of people's living standards, and the rapid development of the automobile industry, people's requirements for automobiles are not only the quality, function and appearance of the automobile itself, but also the requirements for the interior decoration of automobiles are getting higher and higher. . In addition to the basic function of taking a seat in the car, the exterior fabric shape, material and color of the car seat are very important to the user. Generally, the fabric of the car seat needs to be coordinated with the interior decoration style of the real car. Therefore, the seat The selection of chair fabrics, especially the selection and matching of color...
