Abstract
Wrinkle free finishing is a widely used functional finishing process to produce wrinkle-resistant cotton fabrics at the expense of tearing strength of fabrics. In this research, full factors and orthogonal experiments were carried out to invesitgate the mechnism between the wrinkle recovery and tearing strength of cotton fabrics. Wrinkle recovery angle (WRA) was tested by AATCC Test Method 66–2003. Fabric tearing strength, interwoven resistance, and yarn strength were tested before and after resin treatment by a tensile testing machine. By full factors experiment, it was found that the specimen could achieve its best wrinkle-free performance at 110°C curing temperature, 2.5 minutes curing time, 80% pick-up percentage and 60g/l resin concentration considering fabric tearing strength. It is found out that after resin treatment in optimum condition, it could effectively improve the WRA and at the same time with the minimum lose of tearing strength of fabric.
