Abstract

A ripstop fabric having multi-component polyester filament yarns interwoven into spun yarns in a ripstop pattern.

Claims

1. A ripstop fabric, comprising a woven fabric consisting of:

a first yarn consisting of a spun yarn comprising an intimate blend of at least one cellulose-based fiber and at least one synthetic fiber comprising at least one of a polyester fiber and a modacrylic fiber; and

a second yarn consisting of multi-component polyester filament yarn interwoven with the spun yarn in a ripstop pattern, wherein the first yarn is woven in a first direction and the second yarn is woven in a second direction.

2. The ripstop fabric of claim 1, wherein the spun yarns are weft yarns for the fabric, and the multi-component polyester filament yarns are warp yarns.

3. The ripstop fabric of claim 1, wherein the at least one synthetic fiber is a polyester fiber.

4. The ripstop fabric of claim 1, further comprising a stain and oil repellant finish that is added during a finishing process.

5. Police clothing made with the ripstop fabric of claim 1.

6. Military clothing comprising the ripstop fabric of claim 1.

7. A method of forming a ripstop fabric, comprising a weaving step:

wherein the weaving step consists of weaving a plurality of multi-component polyester filament weft yarns with a plurality of spun warp yarns in a ripstop fabric pattern; and

wherein the warp yarns consist of an intimate blend of at least one cellulose-based fiber and at least one synthetic fiber, the at least one synthetic fiber comprising at least one of a polyester fiber and a modacrylic fiber.

8. The method of claim 7, further comprising adding a stain and oil repellant finish during a finishing process.

9. The method of claim 7, further comprising forming the fabric into police clothing.

10. The method of claim 7, further comprising forming the fabric into military clothing.

11. A ripstop fabric, comprising a woven fabric consisting of:

a first yarn consisting of spun yarn, the spun yarn comprising an intimate blend of at least one cellulose-based fiber and at least one synthetic fiber comprising at least one of a polyester fiber and a modacrylic fiber; and

a second yarn consisting of one or more uncovered mechanical stretch filaments;

wherein the second yarn is interwoven with the spun yarn in a ripstop pattern.

12. The ripstop fabric of claim 11, wherein the fabric comprises warp yarns and weft yarns;

and wherein all of the warp yarns are spun yarn and all of the weft yarns are uncovered mechanical stretch filaments.

13. The ripstop fabric of claim 11, wherein the one or more uncovered mechanical stretch filaments comprises a multi-component polyester filament.

14. The ripstop fabric of claim 11, further comprising a stain and oil repellant finish that is added during a finishing process.

15. Police clothing made with the ripstop fabric of claim 11.

16. Military clothing comprising the ripstop fabric of claim 11.

17. A method of forming a ripstop fabric, comprising a weaving step:

wherein the weaving step consists of weaving a plurality of mechanical stretch yarn weft yarns with a plurality of spun yarn warp yarns in a ripstop pattern, wherein the weft yarns consist of one or more uncovered mechanical stretch filaments, and wherein the warp yarns consist of an intimate blend of at least one cellulose-based fiber and at least one synthetic fiber, the at least one synthetic fiber comprising at least one of a polyester fiber and a modacrylic fiber.

18. The method of claim 17, further comprising adding a stain and oil repellant finish during a finishing process.

19. The method of claim 17, further comprising forming the fabric into police clothing.

20. The method of claim 17, further comprising forming the fabric into military clothing.
