CONSTITUTION:The objective woven fabric obtained by arranging (A) a low- melting polymer 5 (e.g., polyethylene) partially melting at 180 deg.C in dry heat and (B) a high-melting polymer 6 having a higher melting point than that of the component (A) in, e.g., a side-by-side form, to provide a heat bonding fiber 1, mixing >=2wt.% resultant fiber with a heat-nonbonding fiber, spinning the obtained mixed fibers, using the resultant spun yarn as a ground yarn 3, weaving a pile fabric with a pile yarn 4 and subsequently heat-treating the resultant pile fabric at a higher temperature than the melting point of the component (A).

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to textiles having napped pile yarns, such as towels and moquettes.

<Prior Art> Fabrics such as towels and moquettes are made up of a basic structure called ground thread and a raised part called pile thread. The pile yarn is usually fixed in a space formed by the warp and weft of the ground yarn. The degree of shedding of the pile yarn is determined by the weaving density of the warp and weft. That is, it is determined by the size of the space between the warp and weft.

Conventionally, various measures have been taken to prevent this pile yarn from falling out. For example, by making a fabric using heat-shrinkable yarn for the warp or weft, and then heat-treating it, you can shrink the shrinkable yarn and increase the density of the warp and weft to prevent yarns from falling out of the pile, or to create a pile fabric. After that,
There is a method of preventing pile shedding by coating the back side of the fabric with a thermosetting resin or the like to bond the pile yarn and ground yarn.

<Problems to be Solved by the Invention> In pile fabrics using heat-shrinkable threads, the weight per unit area of the fabric increases due to shrinkage of the shrinkable threads after heat treatment, resulting in a heavy pile fabric.

In addition, since the warp and weft of the ground yarn have a tight structure, the fabric becomes stiff and has poor drape properties.

Those with resin bonded to the back side of the pile have the disadvantage that the resin may fall off when washed many times or the like, and that they cannot be used for items such as pile fabrics that have pile threads on both sides. The present invention aims to provide a fabric that prevents pile yarns from coming out by preventing several types of pile yarns from being juxtaposed.

Means for Solving the Problems The present invention provides a pile fabric characterized in that a spun yarn containing heat-adhesive fibers that at least partially melts at a dry heat temperature of 180° C. or lower is used as the ground yarn of a pile fabric. It is a fabric that prevents it from coming off.

First, it is essential that the heat-adhesive fiber is partially melted at a dry heat temperature of 180° C. or lower. This is usually done by taking into consideration the general temperature at f2, considering the heat treatment when dyeing and finishing pile fabrics, and of course, it can be considered that the treatment is performed at an even higher temperature. However, when treated at such temperatures, there are adverse effects on other pile fabrics, such as hardening of the texture and reduction of color fastness. Preferably 9
It is a fiber that has a portion that melts at 0°C to 130°C. The thermoadhesive fibers are preferably fibers made of 100% of a low melting point polymer, or have a core-sheath structure (Figure 2) or a side-by-side structure (Figure 3) with another polymer having a higher melting point than the low melting point polymer. . In the former type of fiber, a low melting point polymer is placed in the sheath. In FIGS. 2 and 3, 5 indicates a low melting point polymer and 6 indicates a high melting point polymer. Incidentally, undrawn fibers such as polyester can be used as such fibers. These fibers are used in textiles by blending them with other materials as ordinary spun yarns, or by making them into core-sheath dual-structure yarns called core yarns.

The core yarn referred to herein is a composite yarn in which a plurality of high-melting point fibers and a plurality of low-melting point fibers form a core-sheath structure. (Fig. 5) It is necessary that the heat-adhesive fibers should be present in a content of 2% by weight or more, preferably 15% by weight or more in the ground yarn of the pile fabric, and when it is 2% by weight or less, the pile fabric The slip-off prevention effect is significantly reduced and it no longer fulfills its role. Moreover, when using thermal adhesive fibers at a low mixing ratio, a spun yarn called core yarn is preferable. In other words, if heat-adhesive fibers are used as the sheath component of the core-sheath structure, the pile shedding prevention effect can be obtained at a low mixing ratio. The spun yarn thus produced is used for the warp, weft, or both of the ground yarns of a pile fabric.

After the spun yarn of the present invention is used in a pile fabric, when it is heat-treated at a temperature higher than the melting point of the low-melting point polymer, the low-melting point polymer melts and may melt and adhere to some of the fibers constituting the pile yarn. The substance melts and penetrates into a part of the pile yarn or covers a part of the constituent fibers of the pile yarn, and as a result, it is possible to prevent the pile yarn from coming off. In this case, the density of the ground yarn of the pile fabric is not as high as in case B, since shrinkable yarn is used, and the drapability is good, and like when bonded with resin, it easily falls off when washed. No. Examples of low melting point polymers include mature plastic polymers such as polyethylene, polypropylene, polyamide, polyester, and modified polymers thereof.

FIGS. 2 and 3 show the core-sheath structure and side-by-side structure of a fiber made of a high melting point polymer and a low melting point polymer. Fourth
