Abstract

Provided is commingled yarn excellent in strength. The commingled yarn comprises a continuous thermoplastic resin fiber and a continuous reinforcing fiber as fiber components, which has twist.

First claim

1 . A commingled yarn comprising a continuous thermoplastic resin fiber and a continuous reinforcing fiber as fiber components, which has twist.

2 . The commingled yarn according to claim 1 , wherein the continuous thermoplastic resin fiber is a polyamide resin fiber.

3 . The commingled yarn according to claim 1 , wherein the continuous thermoplastic resin fiber comprises at least one kind selected from polyamide 6, polyamide 66 and a xylylenediamine-based polyamide.

4 . The commingled yarn according to claim 1 , wherein the continuous reinforcing fiber is a carbon fiber and/or a glass fiber.

5 . (canceled)

6 . (canceled)

7 . (canceled)

8 . (canceled)

9 . (canceled)

10 . The commingled yarn according to claim 2 , wherein the continuous thermoplastic resin fiber comprises at least one kind selected from polyamide 6, polyamide 66 and a xylylenediamine-based polyamide.

11 . The commingled yarn according to claim 2 , wherein the continuous reinforcing fiber is a carbon fiber and/or a glass fiber.

12 . The commingled yarn according to claim 3 , wherein the continuous reinforcing fiber is a carbon fiber and/or a glass fiber.

13 . A weave fabric using a commingled yarn according to claim 1 .

14 . A weave fabric using a commingled yarn according to claim 2 .

15 . A weave fabric using a commingled yarn according to claim 3 .

16 . A knitted fabric using a commingled yarn according to claim 1 .

17 . A knitted fabric using a commingled yarn according to claim 2 .

18 . A knitted fabric using a commingled yarn according to claim 3 .

19 . A composite material obtainable by thermally processing a commingled yarn according to claim 1 .

20 . A composite material obtainable by thermally processing a commingled yarn according to claim 2 .

21 . A composite material obtainable by thermally processing a commingled yarn according to claim 3 .

22 . A composite material obtainable by thermally processing a weave fabric according to claim 13 .

23 . A composite material obtainable by thermally processing a knitted fabric according to claim 16 .

24 . A process for preparing a composite material, comprising preparing a commingled yarn comprising a continuous thermoplastic resin fiber and a continuous reinforcing fiber as fiber components, twisting the commingled yarn, and thermally processing the twisted commingled yarn.

25 . The process according to claim 24 , further comprising weaving or knitting the twisted commingled yarn before the commingled yarn is thermally processed.
