Crosslinking of cellulose is considered a necessary process in creating anti-wrinkling cotton fabrics. In the recent years, the concern of buyers regarding the wrinkle-resistant fabric has increased the demand of easy-care finishes. Formaldehyde based easy care finishes are carcinogenic but still used in the textile industry. Low formaldehyde reagents are being developed and tested to replace formaldehyde based easy care finishes. In this research the low formaldehyde easy care finishes; Fixapret ECO and Alkaknit WFR were investigated for their effect on color fastness to crocking, tear strength, tensile strength and durable press rating. Findings of the research showed that the there was a subsequent decrease in tensile and tear strength as compared to original fabric with the increase in resin concentration on both type of dyes. From the results we can say that higher the resin concentration, better the washing durability. This is due to the fact that resin decreases the chance of fiber chain displacement. The fabric with navy blue dye displayed much better performance and compatibility with non-formaldehyde resins as compared to turquoise blue dye.
