Recyclable polyester abrasion-resistant sock

Abstract

This invention provides an easily recyclable, abrasion-resistant polyester sock, comprising a sock body with a tubular structure, one end having an opening for the user to put on, and the other end being sealed. It includes a sole layer and an outer layer, wherein the sole layer forms the inner surface of the sock body, contacting the user's foot; and the outer layer forms the outer surface of the sock body, contacting the outside environment. The outer layer is woven from a surface composite yarn and a high-strength yarn. The surface composite yarn provides an anti-slip effect, and the high-strength yarn increases the abrasion resistance of the outer layer, preventing wear and tear. The core-sheath structure of the surface composite yarn allows the long-fiber polymer fibers to form a fuzzy structure similar to short-fiber yarn, thus achieving an anti-slip effect; and the high-strength yarn with high fiber strength prevents the sock body from wearing out and tearing. In areas particularly prone to friction and damage with the shoe, such as the big toe and forefoot, the amount of high-strength yarn is increased to improve durability.

Claims

1. A recyclable and durable polyester sock, comprising: A sock body, having a tubular structure, with an opening at one end and a closed end at the other, comprises: a base yarn layer forming the inner surface of the sock body; and an outer yarn layer forming the outer surface of the sock body; wherein, the sock body is further subdivided according to the position in contact with the user's foot: a heel counter, an arch counter, and a forefoot counter; wherein, the outer yarn layer is woven from a surface composite yarn and a high-strength yarn to reduce friction damage; and wherein, the sock body is made of polyester material for easy recycling.

2. The easily recyclable, abrasion-resistant polyester socks as described in claim 1, wherein, The outer composite yarn is a composite yarn made by winding an outer yarn around a core yarn; wherein the outer yarn is made of polyethylene terephthalate (PET); and wherein the core yarn is made of a composite material of polyethylene terephthalate (PET) and polypropylene terephthalate (PTT), or a composite material of polyethylene terephthalate (PET) and polybutylene terephthalate (PBT).

3. The easily recyclable, abrasion-resistant polyester socks as described in claim 2, wherein, The high-strength yarn is made of polyethylene terephthalate (PET) and has a fiber strength greater than 5 g / d (gram / denier).

4. The easily recyclable and abrasion-resistant polyester socks as described in claim 3, wherein, The base layer comprises yarns formed from polyethylene terephthalate (PET) and thermoplastic polyester elastomer (TPEE).

5. The easily recyclable, abrasion-resistant polyester socks as described in claim 4, wherein, The yarn in the base layer is DTY yarn, and also consists of TPEE yarn and PET yarn, formed by yarn wrapping technology or air jetting technology.

6. The easily recyclable, abrasion-resistant polyester socks as described in claim 5, wherein, The high-strength yarn is set in the forefoot area.

7. The easily recyclable, abrasion-resistant polyester socks as described in claim 5, wherein, The closed end of the sock body further forms a first toe portion and a plurality of second toe portions corresponding to the user's toes; wherein, the high-strength yarn is disposed in the first toe portion.

8. The easily recyclable, abrasion-resistant polyester socks as described in claim 6 or 7, wherein, The outer yarn has an X1 / Y1 specification, where X1 is 45-150 and Y1 is 72-288. The core yarn has an X2 / Y2 specification, where X2 is 30-100 and Y2 is 24-72. X represents the fineness in denier, and Y represents the number of individual fibers. The bottom yarn layer has an X3 / Y3 specification, where X3 is 20-200 and Y3 is 1-200. X represents the fineness in denier, and Y represents the number of individual fibers.

9. The easily recyclable, abrasion-resistant polyester socks as described in claim 8, wherein, The surface composite yarn is either air-composite yarn (ATY) or stretch textured yarn (DTY).

10. The easily recyclable, abrasion-resistant polyester socks as described in claim 9, wherein, The outer and bottom yarn layers may contain one or more of the following: silver ions, copper ions, zinc ions, activated carbon, silicon dioxide, titanium dioxide, chitosan, tea polyphenols, and plant essential oils (e.g., essential oil microcapsules).
