23. The fabric according to claim 1 , wherein the at least one different quality includes a sanded face between the first and second sides.
24. The fabric according to claim 1 , wherein the at least one different quality includes a brightness difference between the first and second sides.
25. The fabric according to claim 1 , wherein the at least one different quality includes an opacity difference between the first and second sides.
26. The fabric according to claim 1 , wherein the at least one different quality between the first and second sides affects fabric performance.
27. The fabric according to claim 26 , wherein the quality is selected from the group consisting of wicking, breathability, water-resistance, stain resistance, comfort, heat transfer, insulation, cooling, flame retardancy, reflectivity, and combinations thereof.
28. The fabric according to claim 27 , wherein the difference is caused by different fiber sizes on the first and second sides.
29. The fabric according to claim 27 , wherein the difference is caused by at least one chemical treatment.
30. The fabric according to claim 1 , wherein the fabric weight ranges between about four oz/yd 2 and about 12 oz/yd 2 depending upon the application.
31. The fabric according to claim 1 , wherein fiber components forming the fabric have weight ranges between about 20 to about 150 denier.
