Description

Technical field of the present invention

The present invention relates to various clothing outerwear, bedding, for example, interior pads such as laid pads and mats, chair upholstery, and toiletries.

Conventional technology and its problems

Conventional materials that have been used for clothing, bedding, etc. include fiber fabrics, leather, synthetic resin sheets, or materials used in combination with foams. Depending on the purpose of use, product weight, odor, weather resistance, durability, washing resistance and the like are required. In particular, in the clothing field, some functions such as breathability and sweating have been sacrificed and have been overlooked.

Purpose of invention

An object of the present invention is to provide a material in which a constituent fiber of each part constituting a three-dimensional woven fabric has been woven, and the lower layer portion is smooth and the upper layer portion has an irregular concavo-convex pattern.

Key points of the idea

The present invention is a three-dimensional woven fabric having a structure in which an intermediate layer of a woven structure of the upper layer surface portion and a woven structure of the lower layer back surface portion is connected by a plurality of pile yarns. Further, the weft yarn of the lower layer portion is constituted by a stretchable yarn, and the weaving width after weaving is adjusted within the range of 80 to 40 (hereinafter referred to as the width index) with respect to the weaving width 100 at the time of weaving. is there. Therefore, the lower layer back surface portion shrinks in the weaving width direction after weaving, and this shrinkage causes irregular deformation in the woven structure of the upper layer portion via the pile yarn of the intermediate layer.
The deformation of the upper layer woven structure constitutes the warp in the warp direction. Further, the size of the upper layer warp can be controlled by the length and density of the pile yarn constituting the intermediate layer. As a practical experience value, the width index due to the weft shrinkage of the lower layer is in the range of 70 to 55.

Example of device

Embodiments of the present invention will be described in detail below with reference to the drawings.
FIG. 1 illustrates the configuration of a loom used when weaving the embodiment of the present invention.
The warp yarn A is supplied to the backrest Br from the warp beam K, divided into upper layer and lower layer lead rods L, fed into the loom body, and reaches the ground heald Kh. On the other hand, the pile yarn B used for the intermediate layer is fed from the pile beam P to the pile-held Ph via the continuous feeding device S and the tension adjusting device Ts.
The weft yarn C of the lower layer woven structure, for example, the Kospun yarn CSY or the high heat shrinkage yarn and the weft yarn D of the upper layer woven structure is applied to the ground yarn A or the pile yarn B each time the ground heald Kh or the pile heald Ph is opened. The weft yarns C and D are fixed by the length R by being inserted at a right angle. In order to stabilize the shape of the cross section of the woven fabric thus woven, heat setting was performed at 150 to 180 ° C. with a tenter so that the width index was in the range of 55 to 50. The heat treatment fixed the width dimension and smoothness of the lower layer woven structure, and relaxed the stress to strain caused by the deformation caused to the intermediate layer pile yarn and the upper layer woven structure.

In the figure, A is a warp yarn, B is a pile yarn, C is a lower layer weft, and D is an upper layer weft.
Next, examples of practical use according to the present invention will be shown.

Claims (4)

The three-dimensional woven fabric according to the present invention is composed of three different layers, a woven structure of the upper layer part, a woven structure of the lower layer part, and an intermediate layer (pile layer). One of the warp and weft yarns in the lower layer of the woven fabric described above, preferably a stretch yarn (cow spun yarn or high heat-shrinkable yarn) is used for the weft, and then heat treated to shrink to an arbitrary width. A structure of a woven fabric having a three-dimensional feature having irregular warp (reversible effect) generated on the surface of the upper layer portion in accordance with a change in the weave density (densification phenomenon) of the lower layer portion shrunk by the heat treatment described in the item.
