Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multilayer knitted fabric having a pile loop structure on one of the outer surfaces of a front and back knitted fabric layer. In particular, the present invention relates to a seat fabric used for furniture, automobile interiors, and the like.

[0002]

2. Description of the Related Art As shown in FIG. 6, a conventional pile structure knitted fabric generally has a ground yarn and a pile yarn knitted by the same feeder, and has a needle loop composed of a ground yarn and a pile yarn and a sinker nose. Is formed from a sinker loop made of a pile yarn formed straddling the frame. When this pile knitted fabric is used as a fabric for a seat, the pile loop on the surface of the fabric is shaved as a processing after knitting, and the fabric is finished in a velvety glossy and high-grade fabric.

[0003]

However, the pile yarn of the fabric processed in this manner is merely anchored to the ground yarn at the needle loop portion as described above, and the pile yarn may fall off due to external force. Occur. For this reason, after the shaving, the back surface is fixed by resin processing or the like, but this may impair the elasticity peculiar to the knitted fabric. The present invention is mainly intended to improve this point,
It is an object of the present invention to obtain a high-grade fabric in which pile yarns after shaving the pile yarn are greatly reduced.

[0004]

SUMMARY OF THE INVENTION The present invention is directed to a back knitted fabric composed of an inner loop forming a double knit knitted fabric, a ground loop composed of a ground yarn and a pile yarn, and a pile yarn formed at least on the outer surface. This is a multilayer knitted fabric having a surface knitted fabric made of a pile loop and a tack loop joining the surface knitted fabric and the back knitted fabric.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The back surface formed by a ground loop, which is a portion that connects a pile yarn and a ground yarn of a surface knitted fabric, is joined to the back knitted fabric of a twill loop by a tack loop of an intermediate layer. . The surface layer may further include a pile loop formed on the inner surface, in addition to the pile yarn formed to protrude on the outer surface. Although not required in the present invention, it is usually planned to shear the pile yarn of the surface layer as a final finish.

[0012]

According to the multi-layer knitted fabric of the present invention, since the back side of the surface knitted fabric in which the pile yarns protrude on the outer surface is covered with the back knitted fabric, the pile yarns fall off greatly after shaving the pile yarns. To decrease. For this reason, it is not necessary to strongly apply resin processing or the like for preventing falling off, and it is possible to obtain a velvet-like glossy and high-grade cloth without impairing the elasticity peculiar to the knitted fabric. In addition, in addition to the above effects, the multilayer knitted fabric including the pile loop in the middle layer does not need to attach sponge or urethane rubber as a backing material, increasing cushioning and heat retention, and further improving durability In addition, the most suitable fabric for seats used in furniture and automobile interiors, etc. with a rich sense of volume can be obtained.
Furthermore, by using a material having good water absorption such as cotton yarn as the material of the knitting yarn, it can be used for diapers and the like.
