Abstract

PURPOSE:To obtain a cushiony material of high durability by heat treatment of a fabric with high-thermal shrinkage synthetic fiber and low- or non-thermal shrinkage synthetic fiber used as one or both of wefts and warps to bend the latter fiber through the shrinkage of the former fiber. CONSTITUTION:A fabric is made by using high-thermal shrinkage synthetic fiber and lower- or non-thermal shrinkage synthetic fiber as one or both of warps and wefts. This fabric is then heat-treated to bend the latter fiber due to shrinkage of the former fiber, thus forming elastic parts on the fabric. The resultant fabric can find wide applications as clothes, supporters, other supporting goods, medical goods such as bandages and industrial materials for e.g. construction and civil engineering.

Description

[Detailed description of the invention] (Industrial application field) The present invention relates to fabrics with rich cushioning properties.

(Prior Art) Carpets, raised fabrics, pile fabrics, and the like are already well known as cushioning fabrics.

(Problems to be Solved by the Invention) The above-mentioned conventional cushioning fabrics cannot provide rich cushioning properties with just one piece of fabric, so in order to further improve the cushioning properties, it is necessary to stack multiple fabrics. In addition, its cushioning properties gradually deteriorate with use over time, and its uses are also limited.

(Means for Solving the Problems) The present invention eliminates the above-mentioned disadvantages of the conventional products, has extremely rich cushioning properties, is durable, and is water resistant, and can be used in clothing, supports, and other sports equipment. It can be used in a wide range of medical supplies such as bandages, as well as civil engineering, construction, and other industrial materials, and includes synthetic resin fibers with high heat shrinkage and synthetic resin fibers with lower heat shrinkage or synthetic resins with no heat shrinkage. A fabric woven by combining resin fibers in diameter, weft, or warp is heat-treated under appropriate temperature conditions, and the elastic part is created by bending synthetic fibers with low or no heat-shrinkability due to heat-shrinkage of heat-shrinkable fibers. Characterized by the formation of
Furthermore, as a plate-shaped cushioning material, a fabric made by combining synthetic resin fibers with high heat shrinkability and synthetic resin fibers with smaller heat shrinkability or no heat shrinkability in diameter or weft is woven under appropriate temperature conditions. It is characterized by forming a wave-shaped elastic part between the flat upper and lower fabrics made of heat-shrinkable fibers or on one side of the fabric by heat-treating the fabric with fibers having low heat-shrinkability or no heat-shrinkability. .

(Function) In the present invention, a fabric woven from synthetic resin fibers with high heat shrinkability and synthetic resin fibers with low heat shrinkability or no heat shrinkability is woven by synthetic resin fibers with high heat shrinkability. However, when heat treatment is performed at an appropriate temperature (80 to 200°C), the fibers with high heat shrinkage will shrink, and the non-heat shrinkable fibers will bend, creating unevenness on the woven surface and forming an elastic part for shock absorption. is formed.

In this case, if the non-heat-shrinkable synthetic resin fibers are relatively rigid, the cushioning properties can be further improved, and the thickness of the fabric is determined from the bond between the highly heat-shrinkable fibers and the non-shrinkable fibers. It can be set depending on the distance up to bonding and the arrangement density of fibers.

Note that the fabric structure using red and weft yarns is arbitrary, but in order to clearly form bends, it is advantageous to use a textured structure other than a plain structure.

(Example) Embodiments of the present invention will be described with reference to the drawings.

As shown in Fig. 2, polypropylene monofilament (2) with low heat shrinkage is flat-woven as a warp, and the warp (
An appropriate number of polyethylene monofilament warps (1) with high heat shrinkage are arranged for every few warps (1) of 2).
Using fabric A as a base material, fabric A is woven by wefting yarns (2) across multiple weft yarns (2).
A tissue woven with threads that do not shrink by heat between the joints of the warp (1) and weft (2), which are highly heat-shrinkable by drying at ℃ for 0.5 to 3 hours. The section is bent by the contraction of the warp threads (1), and in this embodiment, an elastic section (5) is formed by parallel wavy bends as shown in FIG.

Incidentally, the bending form forming the elastic portion (5) can be arbitrarily changed depending on how the synthetic resin fiber (1) having high heat shrinkability in the base fabric A is used as the warp or weft.

In order to obtain the plate-shaped cushioning material having flat upper and lower surfaces according to claim 2, as shown in FIG. The woven fabric A is made into a flat upper and lower surface, and between them, a structure B is formed in which relatively rigid polyester monofilament with low heat shrinkage is used as the warp (3) and polypropylene monofilament with low heat shrinkage is used as the weft (4). After forming portions a in which the upper and lower fabrics A and A and the intermediate fabric B are separated at regular intervals, a bonding portion with the warp (1) having high heat shrinkage is formed, and this is attached to the base material. As in claim 1, 8
By drying at 0 to 200°C for 0.5 to 3 hours, the warp (1) shrinks as shown in Figure 4, and the warp (2)
is restrained by the engaging part and bent at the separated part a and undulates in a wavy shape, making the wavy bends alternately different. Due to the arrangement of many of them, the flat upper and lower fabrics A are formed by contracted warp threads (1). , A shock-absorbing elastic part (5) in which pipe-shaped spaces are arranged in parallel is formed by bending the filament (3) with low heat shrinkage forming the intermediate fabric B between A and A, as shown in the third figure. A corrugated board-like plate-like cushioning material that is flat on both sides is obtained.

Further, a corrugated board-like plate cushioning material having one side flat can also be obtained by a manufacturing method similar to this method.

(Effects of the Invention) According to the present invention, a fabric made of synthetic resin fibers with high heat shrinkability and synthetic resin fibers with low heat shrinkage or no heat shrinkage selected and woven in an arbitrary manner is used as a base material. By heat-treating this at a predetermined temperature condition, an elastic part for shock absorption can be easily obtained by bending the fibers with low heat shrinkage as the fibers with high heat shrinkage shrink, and the bending of the elastic part The shape can be changed by changing the woven structure of synthetic fibers with high heat shrinkability, and the thickness as a cushioning material can be made uniform by changing the woven structure. Not only can you freely adjust the cushioning properties by selecting the type and thickness of the fibers used, but also the elasticity can be further increased by polymerizing multiple fibers. Moreover, due to its durability, it is used in a wide range of areas and has the effect of obtaining a general-purpose plate-shaped cushioning material for various industries.
