Abstract

PURPOSE:To finish thinly, to facilitate production and to improve durability. CONSTITUTION:A tape' 13 made of thermoplastic resin such as polyurethane having stretchability is made into an U-shaped section and the end 11 of a knitted product 10 is coated with the tape. The outer periphery of the tape 13 is covered by ring sewing 14. By heat melting of the tape 13, the tape 13 is fixed to the knitted product 10 to prevent deviation of position and yarn of the ring sewing 14 is immobilized to check frays.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for treating the edges of knit products such as supporters and socks to prevent them from fraying.

0002

2. Description of the Related Art Conventionally, edge treatments for knit products such as supporters have been used as shown in FIGS. 2 and 3.

That is, first, from the starting point 3 of the edge 2 of the knitted product 1, a rubber tape 4 having a U-shaped cross section is wrapped and chain-stitched 5 along the edge 2. edge 2
to cover. After going around the edge 3 in this manner and reaching the starting point 3, chain stitching is continued without covering the edge 3 with the tape 4, and the protrusion 6 is formed, and the sewing is completed. After this, the protrusion 6 is cut and removed. If left as is, the thread of the chain stitch 5 will become frayed, and the tape 4 will become misaligned within the chain stitch during use. Therefore, zigzag stitches are performed near the starting point 3 to form bar tacks 7, and the ends of the chain stitch 3 are sewn. and the tape 4 are fixed.

[0004] In this conventional process, in order to bartack,
Processing is time consuming. Furthermore, since a rubber tape is used, the edge portion becomes thicker and the tightening force becomes stronger, resulting in an unsatisfactory feeling of use. In particular, the bar tacking part becomes hard, so it feels strange. If used for a longer period of time, thread breakage,
The tape may be cut or misaligned, the thread may become frayed, and the tape may protrude from the chain stitch.

[0005]

[Problems to be Solved by the Invention] The object of the present invention is to eliminate these inconveniences and to obtain an edge treatment structure that has excellent workability during manufacturing and excellent durability during use. It is.

[0006]

[Means for Solving the Problems] The structure of the present invention is to wrap an edge of a knit product by making a stretchable thermoplastic resin tape into a U-shaped cross section, and to cover the edge of the knit product near the tape. The outer periphery of this tape is covered with a chain stitch while forming a seam along the side, and the tape is fixed to the knitted product by heat fusion to prevent the tape from shifting, and the thread of the chain stitch is fixed to prevent fraying. This is the edge treatment structure of knit products that prevents this.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure of the present invention will be specifically explained below in accordance with its manufacturing procedure with reference to FIG.

First, in the same manner as in the past, a chain stitch 14 is made from the starting point 12 of the edge 11 of the knitted product 10 such as a supporter, while wrapping the tape 13 in a U-shaped cross section along the edge 11. and cover this edge 11. The tape 13 used here is made of a stretchable thermoplastic resin such as polyurethane, for example, "Esmer UR" manufactured by Nippon Matai Co., Ltd.
"S" can be used. Note that the appropriate thickness of this tape 13 is about 30 to 100 micrometers. Also, the softening temperature of this tape 13 is naturally the same as that of the knit product 1.
It is necessary to be low enough so as not to damage 1, but 1
A temperature of about 50 to 170 degrees is sufficient for practical use. For the chain stitch 14, any sewing method can be used, such as an over-lock stitch, as long as it forms a seam in the knit product near the tape 13 and covers the outer periphery of the tape 13.

After going around the edge 11 in this way and reaching the starting point 12, the tape 13 is cut, the chain stitch 14 is stopped, and the thread is cut.

[0010] After this, the edge part is heated with an iron or the like to melt the tape 13 once, and this tape 13 is fused to the edge 11. At the same time, the thread of the chain stitch 14 is also fused to this tape 13 and processed. complete.

The structure of the present invention is formed by the above procedure, but it goes without saying that it can also be formed by other procedures. For example, it is also possible to cover the edges with tape and heat it to fuse it, then chain stitch it, and then heat it again to fuse the chain stitch thread. According to this procedure, heating is required twice, but chain stitching becomes easy.

0012

[Effects of the Invention] As mentioned above, the edge treatment structure of the present invention uses a stretchable thermoplastic resin tape.
It can be made thinner than when using conventional rubber tape. In other words, the thickness of conventional rubber tapes is limited to about 0.3 mm, and it is impossible to make the tape thinner than this, but the resin tape of the present invention can easily be made thinner than 100 micrometers. Can be done. Therefore, the tightening force on the edge portion will not be excessive compared to other portions, and the edge portion will not dig into the skin during use. Furthermore, during manufacturing, there is no need for treatments such as bar tacking, which were conventionally necessary, and it is sufficient to simply heat the tape, so manufacturing efficiency is improved and at the same time, deterioration in the feel of the bar tacking portions is prevented. Further, since both the tape and the chain stitch are fixed to the knit product, even after long-term use, the tape will not shift, the chain stitch will not protrude, or the threads will become frayed.
