Problems solved by technology

[0003] However, the existing integrated molding process of polyurethane seats is quite complicated, and has very strict requirements on fabrics and processing. Accurate temperature control and high vacuum degree of the mold cavity are required, but the above problems have always hindered the development of integrally formed seats.

Abstract

The invention relates to an integrally-formed automobile seat and a preparing method thereof. The automobile seat comprises a composite woven fabric seat base matrix integrally heated and formed and first non-woven needled combined short fiber cloth wrapped on the surface of the whole composite woven fabric seat base matrix. During preparation, opening and carding of a carding machine are conducted on combined short fibers, the short fibers are flatly spread to form a combined short fiber net, second non-woven needled combined short fiber cloth is prepared through needling, cospinning is conducted on the second non-woven needled combined short fiber cloth and strengthened woven fabric, the second non-woven needled combined short fiber cloth and the strengthened woven fabric are alternatively overlapped to commonly form the composite woven fabric seat base matrix, the first non-woven needled combined short fiber cloth is wrapped on the surface of the composite woven fabric seat base matrix through needling, the composite woven fabric seat base matrix is put into an automobile seat mold to be integrally heated and formed, and therefore the integrally-formed automobile seat is prepared. Compared with the prior art, the main material of the integrally-formed automobile seat is the composite fiber material, the mass is lighter, the surface material is the TPEE material, elasticity is good, a comfortable riding experience can be provided for passengers and a driver, and the integrally-formed automobile seat is suitable for mass production.

Description

technical field [0001] The invention belongs to the technical field of car seats, and relates to an integrally formed car seat and a preparation method thereof. Background technique [0002] In recent years, in order to reduce the quality of the whole vehicle, reduce the cost and improve the competitiveness, automobile manufacturing has mostly used plastics and composite materials to replace metals. With the continuous development of the chemical industry and the mechanical industry, the integrated molding process of automobile seats came into being. The so-called one-piece molding refers to the vacuum forming of the seat fabric jacket in the foaming mold cavity, and then filling and foaming in the same mold cavity. In the past few decades, many experts and manufacturers have done a lot of work in this area, applying this seat molding technology to cars. [0003] However, the existing integrated molding process of polyurethane seats is quite complicated, and has very stric...
