Benefits of technology

The present invention provides a pile fabric with a ground structure and a cut pile portion that exhibits a high-grade appearance and smooth touch. The cut pile density is 40,000 to 300,000 dtex / cm2, and the single fiber fineness and cut pile length are in the ranges of 0.1 to 2.0 dtex and 0.20 to 2.00 mm, respectively. The cut piles have a polyester-based fiber yarn at the point of recyclability. The method involves weaving or knitting a pile fabric with a ground structure and a cut pile portion, applying a thermal treatment to the fabric to thermally shrink the cut piles, and using yarns with a boiling water shrinkage of not less than 20% and / or false-twisted yarns with a crimp percent of not less than 30% in the ground structure portion. The pile fabric can be used as a vehicle interior material.

Problems solved by technology

However, when such the flocked pile fabrics have been used as car sheet members, there has been a problem that the adhesive forces of the roots of the cut piles have been deteriorated to cause the coming-off of the cut piles from the ground structure portions during the repeated getting-on and off movements of passengers, because the roots of the cut piles have chemically been adhered to the ground structure portions.
As a method for preventing such the cut pile coming-off, the patent document 1 has proposed to knot the root portions of the cut piles, but has sufficiently not solved the problem of the cut pile coming-off due to the deterioration of the adhesive forces, because a chemical adhesion treatment has basically been applied.

[0038] Examples and Comparative Examples of the present invention will be explained in more detail hereafter, but the present invention is not limited to Examples and Comparative Examples. Additionally, measurement items in Examples and Comparative Examples were measured by the following methods, respectively.

[0039] (1) Pile Coming-Off Quantity (PCO)

[0040] A 70 mm-wide, 300 mm-long test fabric was prepared in the warp direction of the pile fabric. A 70 mm-wide, 300 mm-long test fabric was also prepared in the weft direction of the pile fabric. A slab urethane foam having the same size as that of said test fabric was attached to the back side of the prepared test fabric. Then, both the ends of said test fabric were fixed to the slab urethane foam in a non-loose state. The 140 mm-long area of the test fabric was reciprocatedly rubbed with a 9.8±0.098 N-loaded rubbing member having a contact area of 20 mm×20 mm 10,000 times at a rate of 60±10 times / min. The test was carried out in ea...

example 1

[0061] A copolyester having a relative viscosity of 1.45 was prepared from an acid component comprising terephthalic acid and isophthalic acid in a molar ratio of 93 / 7 and a glycol component comprising ethylene glycol. This copolyester resin was melt-spun, and wound up at a winding rate of 3,500 m / min to produce the partially oriented un-drawn copolyester multifilament. The undrawn multifilament yarn was drawn between the 65° C. first roller and the 75° C. second roller of a drawing machine at a draw ratio of 1.4 without being thermally set to obtain the copolyester filament yarn (yarn count: 100 dtex / 12 filaments) which was used as a yarn for a ground structure. The boiling water shrinkage (BWS) of the copolyester filament yarn was 65%.

[0062] Meanwhile, the same copolyester as the above-described copolyester was melt-spun and wound up at a winding rate of 3,500 m / min to produce the partially oriented un-drawn copolyester multifilament. The partially oriented un-drawn copolyester m...

[0067] A pile knitted fabric was produced similarly as in Example 1 except that false-twisted crimped yarns (yarn count: 167 dtex / 48 fibers) comprising ordinary polyethylene terephthalate and having a crimp percent of 40% were used as the yarns for the ground structure in Example 1. Then, the tip portions of the piles of the above-described pile knitted fabric were cut in a length of 0.15 mm with a conventional shearing machine (manufactured by Nikki (Ltd.) to obtain the pile fabric having cut piles having a cut pile length of 0.85 mm. Thereafter, the treated pile knitted fabric was subjected to the same thermal treatment, dyeing treatment, cut pile-standing treatment, and dry heat treatment as those in Example 1 to obtain the pile fabric having a cut pile portion cut pile density of 105,000 dtex / 6 m2, a cut pile length of 0.68 mm, an inclination angle of 78 degree and a cut pile single fiber fineness of 0.49 dtex. The obtained pile fabric exhibited a pile coming-out quantity (PCO) ...

Abstract

A pile fabric having a ground structure portion having a knitted or woven structure comprising organic fiber yarns and a cut pile portion comprising cut piles knitted or woven in said ground structure and having a single fiber fineness of 0.1 to 2.0 dtex is woven or knitted, ant then subjected to a thermal treatment to thermally shrink the above-mentioned cut piles to obtain the pile fabric in which the cut pile density of the cut pile portion is in a range of 40,000 to 300,000 dtex / cm2 and the cut pile length of the cut piles is in a range of 0.20 to 2.00 mm. If necessary, said pile fabric is used to obtain a vehicle interior material.

Description

TECHNICAL FIELD [0001] The present invention relates to a pile fabric having a ground structure portion and a cut pile portion. In more detail, the present invention relates to a pile fabric having a ground structure portion, and a cut pile portion comprising cut piles knitted or woven in said ground structure portion, and exhibiting the same high grade appearance and smooth touch as those of a flocked pile fabric having a large cut pile density and a small cut pile length, and to a method for producing the same. BACKGROUND ART [0002] Hitherto, pile fabrics composed of cut pile portions and ground structure portions have been used in wide fields, because of having excellent appearances and surface touches. Especially, flocked pile fabrics obtained by electric flocking called flocking processing exhibit high grade appearances and smooth touches originated from the compacted touches and ultra small cut pile lengths of cut piles, because of having large cut pile densities and small cut...
