Abrasion resistant fabric

Abstract

The invention relates to a woven fabric comprising a weft yarn, an outer layer with warp yarn A and an inner outer layer with warp yarn B, wherein the weft yarn comprises a combination of individual yarns comprising UHMWPE yarns and individual natural yarns, the warp yarn A comprises at least 50 wt % of a natural fiber, and warp yarn B comprises a combination of individual UHMWPE yarns and individual natural yarns, and said outside and inside layer being at least partially interconnected by the weft yarn. The invention also relates to products comprising said woven fabric such as clothing, lining, sport apparel, and gloves.

Claims

1. A woven fabric comprising a weft yarn and two warp yarns A and B, wherein the weft yarn comprises a combination of: individual yarns comprising ultrahigh molecular weight polyethylene (UHMWPE) yarns, and individual natural yarns, wherein the amount of yarns comprising the UHMWPE yarns in the weft yarn is between 33 and 66 wt % of the total amount of weft yarn; the warp yarn A comprises at least 50 wt % of a natural fiber; and wherein the warp yarn B comprises of a combination of: individual UHMWPE yarns, and individual natural yarns, wherein the amount of UHMWPE yarns is between 10 and 50 wt % of the total amount of the warp yarn B; and wherein the fabric has an outside layer comprising the warp yarn A and an inside layer comprising the warp yarn B and the outside and inside layer being at least partially interconnected by the weft yarn.

2. The woven fabric of claim 1, wherein at least a part of the amount of the yarns comprising UHMWPE yarns in the weft yarn is between 40 and 60 wt % and is arranged in alternating fashion with individual natural yarns.

3. The woven fabric of claim 1, wherein at least a part of the UHMWPE yarns in the warp yarn B is arranged in alternating fashion with individual natural yarns.

4. The fabric of claim 1, wherein warp yarn A additionally comprises natural fibers selected from the group consisting of cotton, hemp, wool, silk, jute, linen and/or synthetic fibers including polyamides, polyesters, polytetrafluoroethylene, polyolefins, polyvinyl alcohols and polyacrylonitriles.

5. The fabric of claim 1, wherein the warp yarn B is a spun yarn.

6. The fabric of claim 1, wherein the weft yarn comprises individual yarns comprising UHMWPE spun yarns.

7. The fabric of claim 1, wherein the warp yarn B further comprises at least one third fiber selected from the group comprising cotton, hemp, wool, silk, jute, linen and synthetic fibers of polyamides, polytetrafluoroethylene, polyesters, polyolefins, polyvinyl alcohols and polyacrylonitriles.

8. The woven fabric of claim 1 wherein the UHMWPE yarns in the warp yarns B are arranged in a clustered manner, comprising clusters of between 1-20 individual UHMWPE yarns.

9. The woven fabric according to claim 1, wherein the warp yarn B consists of a combination of individual UHMWPE yarns and individual natural yarns, the amount of UHMWPE yarns being between 10 and 50 wt % of the total amount of warp yarn B.

10. The fabric of claim 1, wherein the warp yarn A substantially consists of cotton, the warp yarn B is a spun yarn substantially consisting of UHMWPE staple fibers and natural staple fibers and the weft yarn comprises of individual natural yarns and individual yarns comprising UHMWPE yarns.

11. The fabric of claim 1, wherein the weft yarn comprises individual natural yarns and individual yarns comprising UHMWPE yarns, preferably UHMWPE spun yarns, and synthetic fibers, such as polyamide fibers, and/or at least one continuous elastic filament.

12. The fabric of claim 1, wherein the individual natural yarns are selected from the group consisting of cotton, hemp, wool, silk, jute, linen.

13. The fabric of claim 11, wherein the synthetic fibers are selected from the group consisting of polyamides, polytetrafluoroethylene, polyesters, polyolefins, polyvinyl alcohols and polyacrylonitriles.

14. A product comprising the fabric according to claim 1, wherein said product is selected from a group comprising clothing, lining, sport apparel, and gloves.

15. A textile product which comprises the fabric of claim 1.

Description

EXAMPLES

(1) Woven fabrics were produced using double weave beam technology providing 2 warp yarns: warp yarn A (outer layer) and warp yarn B (inner layer) and a weft yarn in a 1/3 twill arrangement. Different yarn compositions have been employed as warp yarn A, warp yarn B and weft yarn, forming single layer fabrics with outer side and inner side:

(2) Yarn I: Ne9.5/1 100% cotton spun yarn

(3) Yarn II: Nm34/2 100% Dyneema® SK75 spun yarn

(4) Yarn III Nm21 Dyneema®/Nylon/Spandex 66/33/5 wt %, based on the total amount of Yarn III, i.e. i) individual yarns 34 Nm (294 dtex) Dyneema® SK75 spun yarn, and ii) individual yarns of elastane continuous filaments (Spandex, 40 denier/3 filaments), with the elastane yarns being covered by Nylon 6,6 individual yarns (78 dtex, 23 filaments texturized), with i) and ii) being twisted together to form a 476 dtex (Nm21) Yarn III containing 62 wt % Dyneema® SK75 yarn, 33 wt % Nylon 6,6 yarn, 5 wt % elastane yarn, based on the total composition of Yarn III.

(5) Yarn IV: Nm21 cotton spun yarn

(7) Table 1 clearly shows that the woven fabric according to the present invention (Example 1) reaches the same abrasion resistance level (A) the Comp. Ex. A, by using with only half of the amount of UHMWPE yarns. By using lower amount of UHMWPE yarn, the wearing comfort for the woven fabric according to the present invention also increases.
