Wrinkle recovery is the property of a fabric that enables it to recover from folding deformations. In this study, wrinkle recovery angle is determined according to the standard method of AATCC (66-2008) by using Shirley Crease Recovery Tester. This test method is used to determine the wrinkle recovery of woven fabrics. It is applicable to fabrics made from any fibre, or combination of fibres. The wrinkle recovery angle of the treated sample is obviously increased by wrinkle resistant finishing. By observing on Fig.1 (a) and (b), the wrinkle recovery angle is considerably increased at the 6% concentration of crosslinking solutions. It may be due to the fact that crosslinking agent produces crosslinks among fibroin molecules of the silk and masks the free hydroxyl side groups, which in turn reduces the swelling and subsequently improves the wrinkle resistant properties of treated fabrics. In the case of both Citric acid and BTCA, with the increase of the concentration of crosslinking agents to 6%, the wrinkle…show more content…
It may be due to the fact that wrinkle resistant finish forms a layer on the surface of fabric and makes the fabric more compact, which leads to increase in weight of fabric. (4) Effect of Treatment on Air Permeability The air permeability of a fabric is the volume of air measured in cubic centimetres passed per second through 1cm2 of the fabric at a pressure of 1 cm of water. From the comfortable point of view, the greater the air permeability value of a fabric, the more the body comfort is. The results of air permeability of the treated samples are obviously reduced as compared to that of the untreated samples as shown in Table.2 and Fig.4. It may be due to the fact that the crosslinking agent fills partially the interstices between the yarns of the fabric that reduces the air permeability. Another reason may be that the surface coating is formed by wrinkle resistant
