“…These results are consistent with those reported previously. 24 The crease recovery characteristics of fabrics have a dramatic effect on the quality of the final product. Figure 4 shows the effect of the ALD process on the crease recovery properties of the bare silk fabric and TiO 2 -coated silk fabric samples in the dry and wet states.…”

Ultraviolet (UV)-protective textiles have attracted significant attention because of their wide applicability. However, the anti-UV coatings of such textiles have an adverse effect on their wearing comfort, and other properties related to luster, softness and handle were also ignored. In this study, TiO2-coated silk fabric with controllable UV-protection properties was successfully fabricated via atomic layer deposition (ALD). The luster, bending properties, crease recovery, mechanical properties, air permeability and anti-UV properties of the TiO2-coated silk fabric were investigated. The results showed that the thickness, whiteness, bendability, tensile strength and anti-UV properties of the silk fabric increased progressively while its air permeability, wet crease recovery angle and dry crease recovery angle decreased with an increase in the thickness of the TiO2 coating. However, the coating did not have a negative effect on the usability of the fabric. Thus, the proposed ALD method is a promising one for modifying the surfaces of elastic textile materials in order to accord them with UV-protection properties.

Bombyx mori silk fabrics were chemically modified by EPSIB (a multifunctional silicone-containing epoxy crosslinking agent). The reactivity of the epoxy groups with silk fibroin was studied by using amino acid analysis. The physical properties of the modified silks such as resiliency (both wet and dry), moisture regain, dyeing behaviors, and solubility in a mixture solvent (C 2 H 5 OH ϫ CaCl 2 : H 2 O ϭ 2 : 1 : 8, molar ratio) were examined. The modified silk fabrics exhibited a significantly improved resiliency, a small increase in moisture regain and whiteness, and a slightly decreased tensile strength. The contents of Serine, Trosine, Lysine, and Histidine decreased linearly as the wet crease recovery angle (CRA) increased. The solubility in the mixture solvent also decreased as the wet CRA increased. The changes of physical properties, especially the wet CRA, were mainly due to the presence of stable crosslinks between silk fibroin and epoxy groups. The DSC and TGA analyses showed that EPSIB-modified silk fibroin had a higher thermal stability compared with the control. © 2004 Wiley Periodicals, Inc. J Appl Polym Sci 91: 3579 -3586, 2004

“…16 The mechanical properties of silk fabrics modified with epoxide compounds were analyzed on the basis of bending, in-plane shear and compressional characteristics experiments. 17 In addition, the value of the mechanical behavior of the silk fabrics, including shearing stiffness (G), and shearing hysteresis (2HG), can be largely attributed to the increase in the contact pressure between warp and weft yarns. However, there is no research on KES evaluation for wool fabrics grafted with vinyl polymers, such as poly(methacrylamide) (MAAm) and poly(2-hydroxyethyl methacrylate) (HEMA).…”

Wool fabrics were graft copolymerized with methacrylamide (MAAm) and 2-hydroxyethyl methacrylate (HEMA) in aqueous media, using a chemical redox system as an initiator. After grafting, the mechanical properties related to the hand evaluation, such as tensile, shearing, bending, compression and surface properties of wool fabrics, were evaluated by means of the Kawabata Evaluation System for Fabric. The surface morphology was examined by scanning electron microscopy. The results revealed that the surface morphology and low-stress mechanical properties of wool fabrics were remarkably changed after grafting with HEMA. The weight gain of the wool fabrics grafted with HEMA increased rapidly in the initial grafting stage and reached saturation level at 17 wt% after 20 minutes. Small deposits of oligomers were visible on wool surfaces and typical scale patterns were changed after grafting wool fabric with HEMA. The slope of the shearing hysteresis curves in the weft and warp directions for wool fabrics grafted with HEMA was increased compared with the control and wool fabrics grafted with MAAm. These results imply that the changes in tensile, shearing, bending and compression behavior of grafted wool fabrics are due to the reduction of the free internal volumes of the fabrics, leading to a tightening of its texture.
