Description

  The present invention has an object to provide a trenker that is comfortable to wear and simple in manufacturing, particularly by fixing a user's heel part firmly and easily, with respect to a trenker that is a sock having a hollowed heel part. .

  The sock tends to slip and rise from a fixed position when worn by constantly receiving gravity and frictional force from the footwear while being worn on the user's foot. In this respect, the trender is a sock having a shape with an open heel portion, and the user's foot can be firmly fixed to the hollowed portion, thereby preventing the slipping and the sliding.

The conventional socks and the manufacturing method thereof are as follows. When applying the socks to be manufactured as a trender, the stitched portions that need to be sewn are stitched together, and the stitched portions are melted at a heat or low temperature and fused. (See, for example, Patent Document 1). In addition, as a conventional trender, there are socks and socks manufacturing methods in which when the manufactured socks are applied as a trender, the folded end of the leg part is sewn to the leg part (for example, , See Patent Document 2).

As described above, the present invention provides a hook portion that is cut in a straight line in the vicinity of the Gore line from the end portion of the hook portion to the inside, from the cutting tip portion on the back side of the leg portion and the foot portion. Folding with the inside as a fold, and joining the folded area to the leg and foot parts to form a reinforcing part, the folded part of the folded area has a continuous double knitted fabric with a double thickness. Therefore, the strength of the folded part of the buttocks can be increased and the fit to the user's foot can be improved. In addition, since the incision is performed after the heel portion is once formed, the shape of the instep is naturally maintained as compared with the case where the opening portion of the heel portion is integrally knitted, and the foot portion, particularly A sufficient fit for the instep can be obtained.

  Further, in the trender according to the present invention, if necessary, the reinforcing portion is joined by sewing with one or a plurality of seams along the fold. In this way, according to the present invention, since the reinforcing portion is joined by sewing with one or a plurality of seams along the fold, the folding region is securely fixed by sewing, and the collar portion Furthermore, the strength of the folding part can be further increased, and the fit to the user's foot can be further improved.

  In addition, in the trender according to the present invention, the reinforcing portion is bonded by thermal bonding as necessary. As described above, according to the present invention, since the reinforcing portion is bonded by thermal bonding, the folding region that is difficult to sew is securely bonded by thermal adhesive force, and the strength of the folding portion of the collar portion is increased. Furthermore, it is possible to further improve the fit to the user's foot and simplify the production process, thereby realizing an improvement in quality and a reduction in production costs due to a reduction in production errors.
