Composite fabric with engineered pattern
View Patent ↗A method of forming a composite fabric article includes interlacing yarns including multi-filament fibers to form a fabric body of knit construction, and forming a raised or fleece region upon an inner surface of the fabric body. The method also includes applying a non-continuous coating consisting of discrete coating segments of coating material upon yarn fibers at an outer surface of the fabric body to bind individual yarn fibers together in bound groupings and to enhance abrasion resistance of the outer surface. The non-continuous coating is applied such that the coating is without substantial effect on hand tactile and breathability of the knit construction of the fabric body.
1. A method of forming a fabric article, said method comprising the steps of:
interlacing yarns comprising multi-filament fibers to form a fabric body of knit construction;
forming a raised or fleece region upon an inner surface of the fabric body; and
applying a non-continuous coating in a predetermined and repeating pattern comprising discrete coating segments of between about 0.5 to about 6.0 ounces per square yard of coating material selected from a group consisting of acrylic latex, polyurethane and silicone with a single head rotary screen having from about 30 to about 195 holes per lineal inch upon yarn fibers at an outer surface of the fabric body such that the non-continuous coating is without substantial effect on hand tactile and breathability of the knit construction of the fabric body, thereby to bind individual yarn fibers together in bound groupings and to enhance abrasion resistance of the outer surface.
2. The method of claim 1 , wherein the step of forming a fleece or raised region includes at least one selected from a group consisting of napping, sanding and brushing.
3. The method of claim 2 , wherein the step of forming a fleece or raised region occurs prior to applying the non-continuous coating.
4. The method of claim 2 , wherein the step of forming a fleece or raised region occurs subsequent to applying the non-continuous coating.
5. The method of claim 1 , wherein the step of applying a non-continuous coating comprises applying the non-continuous coating in a discrete area of the outer surface.
6. The method of claim 5 , wherein said discrete area corresponds to an area of the outer surface typically subjected to relatively high levels of pilling or abrasion during use.
7. The method of claim 5 further comprising applying a continuous coating in an area of the outer surface other than said discrete area.
8. The method of claim 5 , wherein an area other than said discrete area is substantially free of coating material.
9. The method of claim 1 , wherein the step of applying a non-continuous coating comprising discrete coating segments of coating material upon yarn fibers at an outer surface of the fabric body to bind individual yarn fibers together in bound groupings protects the fibers from fraying corresponding to an increase in pilling resistance.
10. The method of claim 1 , wherein the discrete segments of coating material are in the form of dots.
11. The method of claim 1 , wherein the step of interlacing yarns comprises double needle bar warp knitting.
12. The method of claim 1 , wherein the step of interlacing yams comprises Raschel warp knitting.
13. The method of claim 1 , wherein the step of interlacing yarns comprises reverse plaited circular knitting.
14. The method of claim 1 , wherein the step of interlacing yams comprises non reverse plaited knitting.
15. The method of claim 1 , wherein the non-continuous coating is applied such that the non-continuous coating is without substantial effect on insulation performance provided by the knit construction of the fabric body.
16. The method of claim 1 , wherein the non-continuous coating is applied such that the non-continuous coating is without substantial adverse effect on moisture vapor transmission rate provided by the knit construction of the fabric body.
17. The method of claim 1 , wherein about 1.7 ounces per square yard of coating material is applied to form the non-continuous coating.
18. A method of forming a fabric article, said method comprising the steps of:
interlacing yarns comprising multi-filament fibers to form a fabric body of knit construction;
forming a raised or fleece region upon an inner surface of the fabric body; and
applying a non-continuous coating in a predetermined and repeating pattern comprising discrete coating segments of between about 0.5 to about 6.0 ounces per square yard of coating material selected from a group consisting of acrylic latex, polyurethane and silicone with a single head rotary screen having from about 30 to about 195 holes per lineal inch upon yarn fibers at an outer surface of the fabric body such that the non-continuous coating is without substantial effect on hand tactile and breathability of the knit construction of the fabric body, and such that the one or more discrete areas including the non-continuous coating have a pilling resistance of five on a scale from one to five, as measured by ASTM D-3512.
