Surface material for vehicle use, producing method thereof, internal decorative material and seat material for automatic two-wheel and tricycle vehicles

Abstract

This invention provides an extremely high-performance surface skin material for vehicles which can readily and accurately be dyed at low cost and excellent in properties which both component fibers have and is relatively inexpensive by carrying out blended spinning of PPT fiber excellent in light resistance and fastness to abrasion and having good touch feeling with a cellulosic fiber excellent in hygroscopic property and flame retardance and dyeing the resultant blended fabric with a vat dye. The surface skin material for vehicles is composed of a blended fabric of PPT fiber and the cellulosic fiber and dyed with the vat dye.

Description

technical field [0001] The present invention relates to a vehicle skin material containing a blended fabric of polyester fibers and cellulose fibers, a method for producing the same, and an automobile interior material and a seat material for motorcycles and tricycles using the skin material at least in the skin portion. Background technique [0002] PET (polyethylene terephthalate) fiber cloth is a kind of polyester fiber, and it is known that such fiber cloth is conventionally used as interior materials for automobiles. [0003] Although this PET fiber is excellent in light resistance and frictional firmness, there is a problem that it lacks hygroscopicity and easily generates static electricity. In addition, because PET fiber has poor affinity with vat dyes (vet dyes), it is difficult to dye with vat dyes, so it is dyed with disperse dyes with a smaller molecular weight than vat dyes but a relatively high price. In addition, because of its fast burning speed, It is neces...

Problems solved by technology

[0006] In order to solve the above-mentioned problems with the existing PET fiber skin materials for automobiles, attempts have been made to blend cellulose fibers such as rayon among natural fibers excellent in hygroscopicity and flame retardancy with PET fibers, but cellulose fibers Fibers are difficult to dye with disperse dyes and PET fibers are difficult to dye with vat dyes, so it is impossible to dye cellulose fibers and PET fibers with the same dye, so either use dope dyed silk, or dye the yarns with dyes separately and then blend them. However, in this case, the reproducibility of the dyeing of the woven fabric is poor, and labor is required, resulting in problems such as an increase in cost and limitations in design, and it has not yet been put into practical use.
