Surgical towels with reduced lint particle generation
View Patent ↗Absorbent surgical towels with reduced lint particle generation are provided. The surgical towels are formed from fibrous substrates containing binder material that limits lint particle generation to 5,000 or less according to INDA standard test 160.1. The binder material can limit lint particle generation to 500 or less.
1. A surgical towel comprising an absorbent fibrous substrate having a binder material that limits lint particle generation to 5,000 or less according to INDA standard test 160.1,
wherein the surgical towel is a nonwoven fabric, and the fibrous substrate comprises one or more nonwoven layers comprising non-absorbing synthetic fibers, a silicone based wetting agent, and the binder material in an amount of about 0.5% to about 10% by weight of the fibrous substrate, and
wherein the towel has a weight of less than about 10 ounces per square yard and has an absorbent capacity of greater than about 250%.
2. The towel of claim 1 , wherein the towel has a thickness of from about 0.010 inch to about 0.30 inch.
3. The towel of claim 1 , wherein the binder material is selected from the group consisting of binder fibers and binder powder.
4. The towel of claim 1 , wherein the fibrous substrate has a lint particle generation of 2,500 or less according to INDA standard test 160.1.
5. The towel of claim 1 , wherein the fibrous substrate has a lint particle generation of 1,000 or less according to INDA standard test 160.1.
6. The towel of claim 1 , wherein the fibrous substrate has a lint particle generation of 500 or less according to INDA standard test 160.1.
7. The towel of claim 1 , wherein the fibrous substrate comprises a laminate of at least two separate nonwoven layers.
8. The towel of claim 1 , wherein the binder material is present in an amount of about 0.5% to about 5% by weight of the fibrous substrate.
9. The towel of claim 1 , wherein the towel is bonded by the binder material.
10. The towel of claim 1 , wherein the towel is adhesively and mechanically bonded by the binder material.
11. The towel of claim 1 , wherein the non-absorbing synthetic fibers are polyester fibers or polypropylene fibers.
12. The towel of claim 1 , wherein the fibrous substrate is a laminate of at least two spunlaced woodpulp/polyester layers.
13. The towel of claim 12 , wherein the binder material is present in an amount of about 0.5% to about 5% by weight of the fibrous substrate.
14. The towel of claim 12 , wherein the towel is bonded by the binder material.
15. The towel of claim 12 , wherein the towel is adhesively and mechanically bonded by the binder material.
16. The towel of claim 12 , wherein the towel has a weight of less than about 10 ounces per square yard and a thickness from about 0.010 inch to about 0.30 inch.
