Absorbent towel with projections
View Patent ↗A towel ( 10 ) includes a base layer ( 12 ) and a plurality of raised projections ( 14 ) that project away from the base layer ( 12 ). The base layer ( 12 ) has a first side ( 16 ) and a second side ( 18 ). In one embodiment, the projections ( 14 ) are discontinuously positioned and are each separately secured to one or both of the sides ( 16, 18 ) of the base layer ( 12 ). In one embodiment, the projections ( 14 ) have a higher coefficient of static friction than the base layer ( 12 ) relative to a surface ( 20 ). The base layer ( 12 ) can be formed from an absorbent material and the projections ( 14 ) can be formed from a relatively non-absorbent material. In one embodiment, the projections ( 14 ) cover less than approximately 50 percent of one of the sides ( 16, 18 ) of the base layer ( 12 ). Moreover, in one embodiment, the projections ( 14 ) can be substantially hemispherical in shape.
1. A towel for use on a surface, the towel comprising:
a base layer having (i) a first side that is at least partially formed from a liquid-absorbing material, and (ii) a second side that is substantially opposite the first side and at least partially formed from a liquid absorbing material, the second side being at least partially exposed; and
a plurality of raised projections that are each separately secured to the first side, the projections having a higher coefficient of static friction than the base layer so that the projections inhibit relative movement between the towel and the surface when the projections are in contact with the surface.
2. The towel of claim 1 wherein the projections are formed from a material that is substantially liquid impermeable.
3. The towel of claim 1 wherein at least one of the projections is formed from a material selected from the group consisting of plastic, rubber and epoxy.
4. The towel of claim 1 wherein the projections are positioned on at least a portion of the first side so that the projections have a density of at least one projection per square inch.
5. The towel of claim 1 wherein at least one of the projections projects at least approximately 0.1 millimeters away from the first side of the base layer.
6. The towel of claim 1 wherein the projections cover less than approximately 90% of the first side of the base layer.
7. The towel of claim 1 wherein at least two of the projections are positioned at least approximately one-quarter inch on center from one another.
8. The towel of claim 1 wherein at least two of the projections are positioned less than approximately one-quarter inch on center from one another.
9. The towel of claim 1 wherein the base layer is at least partially formed from a microfiber material.
10. A towel for use on a surface, the towel comprising:
a base layer having (i) a first side that is at least partially formed from a liquid-permeable material, and (ii) a second side that is substantially opposite the first side and at least partially formed from a liquid-permeable material, the second side being at least partially exposed; and
a plurality of first projections that are each separately secured to the first side, the first projections being formed at least partially from a material that is substantially liquid impermeable, the first projections having a higher coefficient of static friction relative to the surface than the base layer.
11. The towel of claim 10 wherein at least one of the projections is formed from a material selected from the group consisting of plastic, rubber and epoxy.
12. The towel of claim 10 wherein the projections are positioned on at least a portion of the first side so that the projections have a density of at least one projection per square inch.
13. The towel of claim 10 wherein at least one of the projections projects at least approximately 0.1 millimeters away from the first side of the base layer.
14. The towel of claim 10 wherein the projections cover less than approximately 90% of the first side of the base layer.
15. The towel of claim 10 wherein at least two of the projections are positioned at least approximately one-quarter inch on center from one another.
16. The towel of claim 10 wherein at least two of the projections are positioned less than approximately one-quarter inch on center from one another.
17. A method for manufacturing a towel, comprising the step of:
separately securing a plurality of substantially liquid impermeable projections to a substantially liquid-permeable first side of a base layer having an opposing second side that is at least partially exposed, the second side being at least partially liquid-permeable, the projections having a coefficient of static friction that is greater than a coefficient of static friction of at least a portion of the first side of the base layer relative to a surface.
18. The method of claim 17 wherein the step includes covering less than approximately 90 percent of the first side of the base layer with the plurality of projections.
19. The method of claim 17 wherein the step includes positioning the projections to project at least approximately 0.1 millimeters away from the first side of the base layer.
20. The method of claim 17 wherein the step includes securing the plurality of the projections to the first side using a heat treatment.
