Problems solved by technology

[0003] Currently commonly used seat fabrics are woven from ATY yarns, that is, ATY elastic fibers. However, ATY yarns have poor resilience due to structural defects, resulting in insufficient warp and weft extension of some fabrics woven from ATY yarns. Unable to fully meet the requirements of car seat fabrics

Embodiment Construction

[0010] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0011] Such as figure 2 The process diagram shown is a production method of a new type of ATY elastic fiber for vehicles. First, POY is drawn to form a PET material, and POY is drawn to form a PBT elastic material; then the PET material and the PBT elastic material are preheated, and the PBT The elastic material is the core filament, and the PET material is the outer skin, which is air-deformed and entangled to form an air-textured yarn; finally, the air-textured yarn is shaped and wound. Oiling process can also be carried out before winding.

[0012] By implanting high-elastic PBT materials and intertwining and coating, the resilience of ATY yarns of craft...

Abstract

The invention relates to the field of production of seat fabrics, in particular to a novel production method of vehicular ATY (Air Texturing Yarn) elastic fiber. The production method comprises the following steps of: first drafting POY (Polyester Pre-Oriented Yarn) to form a PET (polyethylene terephthalate) material and simultaneously drafting the POY to form a PBT (polybutylene terephthalate) elastic material; preheating the PET material and the PBT elastic material, carrying out air texturing by taking the PET elastic material as core yarns and the PET material as outer skin, and simultaneously, intertwining and wrapping to form the air texturing yarns; and finally sizing and winding the air texturing yarns. According to the novel production method disclosed by the invention, the production process route is simple, the rebound resilience of the ATY elastic fiber product is improved, and economy and environmental-friendliness are achieved.

Description

technical field [0001] The invention relates to the production field of seat fabrics, in particular to a production method of a novel ATY elastic fiber for vehicles. Background technique [0002] Decorative textiles are the main application fields of textiles, and seat-like decorative fabrics refer to the fabrics used to cover sofas and soft chairs. Seats are the dominant part of vehicle interior decoration. At the same time, seat covers, carpets and other decorative fabrics used as automotive interior decoration account for 70% of the entire automotive textiles. It can be seen that automotive seat fabrics have great development potential. In addition to the various performance requirements of traditional textile products, automotive textiles also have special requirements due to their special uses, such as wear resistance, sun resistance, color fastness, UV resistance, antifouling, flame retardancy, easy cleaning and Dimensional stability and other aspects have higher requ...
