Three-dimensional tailored thermal bonding invisible sock

Abstract

The invention discloses a three-dimensional tailored thermal bonding invisible sock. The sock comprises a sock upper and a sock sole, the lower edge of the sock upper is connected with the edge of thesock sole in a sewn mode, a containing cavity is defined by the sock upper and the sock sole, a first hot melt adhesive film is thermally bonded to the upper edge of the sock upper in the circumferential direction and distributed on the inner side and / or the outer side of the sock upper, and a sock opening is defined by the upper edge of the sock upper and is oval. The sock sole part, corresponding to the foot sole, of the sock sole extends upwards to wrap the instep. The sock upper comprises a tiptoe coating part corresponding to the tiptoe, a sole coating part corresponding to the sole anda heel coating part corresponding to the heel, the tiptoe coating part, the sole coating part and the heel coating part are of an integrated structure, the cross section of the heel coating part is arc-shaped, the radian of the cross section of the heel coating part is the same as the radian of the section of the ankle of a human body, and an anti-skid piece is adhered to the hell coating part. The three-dimensional tailored thermal bonding invisible sock is comfortable to wear, durable, anti-falling and capable of preventing allergy.

Description

technical field [0001] The invention relates to the technical field of sock structure design, more specifically, the invention relates to three-dimensional cutting thermally bonded invisible socks. Background technique [0002] At present, for the purpose of beauty and fashion, traditional invisible socks often use accessories such as elastic bands and lace, which will cause a strong sense of pressure on the feet during wearing, and even leave strangulation marks on the feet. Therefore, the traditional The comfort of invisible socks is very poor, mainly manifested as skin allergies and other foot discomfort; in the process of wearing traditional invisible socks, the adsorption force between the ankle and the heel of the socks is small, and the invisible socks are prone to fall off, which will not only affect the comfort , and it is very easy to cause friction between the ankle and the heel of the shoe, which will wear the skin of the human ankle and cause the user unbearable...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the problems of poor comfort, easy falling off, and failure to meet the actual needs of users in traditional invisible socks, the present invention innovatively provides a three-dimensional cutting heat-bonded invisible socks, which has a unique design for the structure of invisible socks. The suture line of the upper and the bottom of the heat-bonded invisible socks is set on the instep. The transverse section of the heel covering part is arc-shaped without protrusions, which fits the feet better. It will not cause allergies, greatly improves the comfort of invisible socks on the whole, and effectively solves many problems existing in traditional invisible socks
