Abstract

Lightweight fabrics with a balance of high thermal properties, especially arc resistance and flash fire resistance, on the one hand, and durability and comfort properties, on the other hand, are disclosed. Articles, such as garments and linen, made from the lightweight fabrics are also disclosed. Spun yarns made with an intimate blend of fibers including flame resistant fiber, fire-resistant hydrophilic fibers, and a low level of anti-static fibers are described. The lightweight fabrics are particularly useful in garments for utility workers, industrial workers, military personnel, and firefighters.

Claims (56)

1. A fabric, comprising:

a spun yarn comprising:

60% by weight to 80% by weight, based on the total weight of the spun yarn, meta-aramid fiber;

7% by weight to 15% by weight, based on the total weight of the spun yarn, nylon fiber;

5% by weight to 15% by weight, based on the total weight of the spun yarn, para-aramid;

less than 2% by weight, based on the total weight of the spun yarn, anti-static fiber, and

10% by weight to 15% by weight, based on the total weight of the spun yarn, fire-resistant hydrophilic fiber;

wherein said fibers are intimately blended; and

wherein said fabric has a basis weight of less than 6.5 oz/yd 2 .

2. The fabric of claim 1 ,

wherein said fabric is a woven fabric.

3. The fabric of claim 1 ,

wherein said fabric is a knit fabric.

4. The fabric of claim 1 ,

wherein said fabric is a non-woven fabric.

5. The fabric of claim 1 ,

wherein said anti-static fiber is present at a level of less than 1.5% by weight, based on the total weight of the spun yarn.

6. The fabric of claim 1 ,

wherein said anti-static fiber is present at a level of less than 1.25% by weight, based on the total weight of the spun yarn.

7. The fabric of claim 6 ,

wherein said woven fabric has a basis weight of less than 6.0 oz/yd 2 .

8. The fabric of claim 1 ,

wherein said meta-aramid fiber is present at a level of 60% by weight to 70% by weight, based on the total weight of the spun yarn.

9. The fabric of claim 1 ,

wherein said nylon fiber is present at a level of 8% by weight to 15% by weight, based on the total weight of the spun yarn.

10. The fabric of claim 1 ,

wherein said para-aramid fiber is present at a level of 8% by weight to 15% by weight, based on the total weight of the spun yarn.

11. The fabric of claim 1 ,

wherein said fire-resistant hydrophilic fiber is present at a level of 12% by weight to 15% by weight, based on the total weight of the spun yarn.

12. The fabric of claim 1 ,

wherein said fire-resistant hydrophilic fiber is present at a level of 10% by weight to 13% by weight, based on the total weight of the spun yarn.

13. The fabric of claim 1 ,

wherein said fire-resistant hydrophilic fiber is selected from the group consisting of cellulosic fiber, wool fiber, silk fiber, fire resistant acrylic derivative fiber, and combinations thereof.

14. The fabric of claim 1 ,

wherein said spun yarn comprises:

85% by weight to 90% by weight, based on the total weight of the spun yarn, hydrophobic component; and

10% by weight to 15% by weight, based on the total weight of the spun yarn, hydrophilic component.

15. The fabric of claim 1 ,

wherein said anti-static fiber comprises a conductive fiber.

16. The fabric of claim 1 ,

wherein said anti-static fiber comprises a carbon fiber with a nylon sheath.

17. The fabric of claim 1 ,

wherein said spun yarn further comprises an elastomeric filament.

18. An article, comprising:

the fabric of claim 1 .

19. A woven fabric, comprising:

a spun yarn comprising:

66% by weight, based on the total weight of the spun yarn, meta-aramid fiber;

9% by weight, based on the total weight of the spun yarn, nylon fiber;

12% by weight, based on the total weight of the spun yarn, para-aramid;

1% by weight, based on the total weight of the spun yarn, anti-static fiber; and

12% by weight, based on the total weight of the spun yarn, FR rayon;

wherein said fibers are intimately blended; and

wherein said woven fabric has a basis weight of less than 6.5 oz/yd 2 .

20. An article, comprising:

the fabric of claim 19 .
