Background
At present, the requirements of textile fabrics are increasingly high, and not only the popular styles and designs of the fabrics are required, but also the fabrics are required to have good performance. One of the important indexes for evaluating the performance of the fabric is the crease recovery performance of the fabric.
The crease recovery performance of fabric is measured by a plurality of methods, but most commonly, the crease recovery angle of a fabric folding sample is measured by folding and pressurizing a fabric sample with a specified shape and size under a certain atmospheric condition for a certain time, and measuring the recovery angle of the fabric after releasing the weight. The position of the crease line of the test piece for determining the recovery angle is classified into a horizontal method and a vertical method. On one hand, the horizontal method is a method for measuring a recovery angle by enabling a crease line to be parallel to a horizontal plane when the crease of the sample recovers; on the other hand, the vertical method is a method for measuring a recovery angle when a sample crease recovers and a crease line is vertical to a horizontal plane. The polyester fabric is firm and durable, has the characteristics of good elasticity, difficult deformation, corrosion resistance, good light fastness and the like, and is a chemical fiber textile fabric in daily life. The conventional process for producing pure polyester fabric comprises the following steps: grey cloth → dye vat deoiling shrink → grey cloth preshaping → dyeing → after finishing and shaping finished products. However, in practical production, cloth surface creases often appear when the process is adopted, and the creases are more serious especially when the fabric is dyed with deep colors.
