Benefits of technology

[0007]In view of the above, it is aimed to provide a fabric that contains partially animal and plant origin fibers and has improved durability against deterioration in appearance and in physical properties even with the lapse of time upon application to a vehicle interior finish material.
[0008]As a result of earnest investigations made by the inventors, it has been found that deterioration of in appearance and physical properties of a fabric with the lapse of time can be suppressed by decreasing exposure of animal and plant origin fibers on the surface of the fabric to a small extent, thereby providing a fabric that has sufficient durability as a fabric for a vehicle interior finish material. The invention has been completed based on the findings.
[0013]According to the invention, such a fabric can be provided that contains partially animal and plant origin fibers and has improved durability against deterioration in appearance and in physical properties, even with the lapse of time upon application to a vehicle interior finish material. The fabric for a vehicle interior finish material of the invention contains partially animal and plant origin fibers, and therefore, the fabric lowly depends on petroleum and provides decreased load on disposal. Therefore, the fabric of the invention contributes to establishment of environment-conscious society as an environmentally benign fabric for a vehicle interior finish material.

Problems solved by technology

However, the animal and plant origin fibers inferior in durability as compared to conventional synthetic fibers, such as polyester fibers, and have not yet been subjected to practical use as a material for a fabric for a vehicle interior finish material.
Upon applying the moquette pile fabric or the nonwoven fabric to a vehicle interior finish material, however, they are deteriorated in appearance and physical properties with the lapse of time and cannot be subjected to practical use.
In particular, the nonwoven fabric disclosed in JP-A-2005-307359 contains the polylactic acid staple fibers that are exposed on the surface of the nonwoven fabric in a large amount, and therefore, suffers considerable embrittlement due to light, heat and humidity.
Furthermore, the composite fibers used in the moquette pile fabric disclosed in JP-A-2005-281891 are limited to so-called core-shell type or sea-island type fibers, which increase the production cost.

example 1

[0058]A double weft woven fabric was woven as a base fabric (loomstate fabric) according to a weaving pattern shown in FIG. 1 in the following manner. A Jacquard loom having 170 warp ends per inch was used. The warp thread used was a pre-dyed thread (thread B1) consisting of; a polyethylene terephthalate multi-filament thread of 33 dtex / 12 filaments as a core; and a two-ply thread formed of polyethylene terephthalate multi-filament threads of 56 dtex / 48 filaments, as a sheath. The back weft thread was a mixed spun thread of a yarn number of 30 / 2 (thread A1) consisting of; polyethylene terephthalate staple fibers of 1.6 dtex and 51 mm; and polylactic acid staple fibers of 1.7 dtex and 51 mm, at a mixing ratio of 50 / 50. The front weft thread was a polyethylene terephthalate pre-dyed multi-filament thread (thread B2) of 167 dtex and 36 filaments. Each of the front and back weft thread was introduced in an arrangement of 1-in / 1-out and 1-out / 1-in, at a density of 116 threads per inch.

example 2

[0061]A plain weave fabric was woven as a base fabric (loomstate fabric) in the following manner. A Jacquard loom having 170 warp ends per inch was used. The warp thread used was a polyethylene terephthalate pre-dyed multi-filament thread (thread B3) of 990 dtex and 324 filaments. The weft threads used were; a “pre-dyed” mixed spun thread of a yarn number of 30 / 2 (thread A2), which consists of polyethylene terephthalate fibers and polylactic acid fibers at a mixing ratio of 50 / 50 and is same as the thread A1 used in Example 1 except for being “pre-dyed” (hereinafter expressed in the same manner); and a polyethylene terephthalate pre-dyed multi-filament thread (thread B4) of 390 dtex and 130 filaments. The thread A2 and thread B4 were alternately introduced at a density of 170 counts per inch.

[0062]The base fabric was then processed in the same manner as in Example 1 as to form the backing layer of the resin, thereby providing a fabric for a vehicle interior finish material according...

example 3

[0063]A fabric for a vehicle interior finish material according to the invention was provided in the same manner as in Example 2 except that a polyethylene terephthalate pre-dyed multi-filament thread (thread B5) of 940 dtex and 313 filaments was used as a warp thread.

Abstract

A fabric for a vehicle interior finish material that contains partially animal and plant origin fibers and has improved durability against deterioration in appearance and in physical properties, even with the lapse of time upon application to a vehicle interior finish material. The fabric comprises a thread A containing fibers derived from a raw material of animal and plant origin and a thread B containing polyester fibers, and has an exposure ratio of the thread A with respect to the surface area of the fabric represented by the following expression being 20% or less:exposure ratio of thread A=(SA / SF)×100wherein SA represents a total area of the thread A exposed on the surface of the fabric, and SF represents the surface area of the fabric.

Description

BACKGROUND OF THE INVENTION[0001]The present invention relates to a fabric for a vehicle interior finish material. More specifically, the invention relates to a fabric that partially contains fibers derived from a raw material of animal and plant origin, and has sufficient durability upon application to a vehicle interior finish material.[0002]A fabric has been used as an interior finish material of a vehicle, such as an automobile, a railcar, an aircraft, a boat and a ship, in various interior articles including a seat, a ceiling, a curtain and the like. A vehicle interior finish material is required to have high durability because it is used under severe conditions for a prolonged period of time, and therefore, as fibers constituting a fabric for a vehicle interior finish material, synthetic fibers excellent in physical and chemical characteristics, particularly polyester fibers, have been used.[0003]Environmental issues such as global warming and issues of petroleum exhaustion ha...
