No, you cannot. While you could resell the fabric "as is" (so long as there was no sales, etc. agreement you signed or agreed to in purchasing the fabric, which agreement bars resale--if there was, it is enforceable against you) but you cannot use the fabric to create new products. Trademark law gives the trademark holder the sole right to use that trademark for commercial purposes (subject to the exception for as is resale); copyright law (and these characters would be copyrighted as well) gives the copyright holder the sole right to create "derivative" or "adapted" works--that is, new or modified products--using the copyright material. Between the two, you cannot use the character fabric to make and sell new products.
