“…Also, test results clearly showed that treated wool fabric with Pulcra HPU emulsion could not meet the Woolmark TM 31 technical standard in less than 3.0% of machine‐washable wool products for any washing cycle. If the results are discussed after 3x5A washing, a commonly used procedure in literature and industry, while Pulcra HPU did not create a significant effect when compared to raw fabric, all SMPU treatments decreased felting shrinkage of the fabric significantly. Performance of Pulcra HPU may be related to thinner film formation on fiber surface which is insufficient to prevent relative mobility of the fibers and cuticle layer.…”

“…Tear strength values in both warp and weft directions were affected negatively from Pulcra HPU application (Table ). On the other hand, significant tear strength increases were achieved with neat SMPU and SMPU‐CNW nanocomposite finishing as a result of thicker film formation on yarns and accumulated polymer among yarns increasing flexural stiffness and stress modulus of fabric especially in weft direction compared to raw and WO‐Pulcra HPU. The tear strength of the fabrics in both warp and weft directions increased with the increase of CNW concentration in the composite structure but the differences were not significant except for the performance of WO‐SMPU‐CNW20 for warp direction which includes the highest CNW concentration.…”

Shape memory wool fabrics having both temperature and moisture responsiveness were fabricated by a functional nanocomposite treatment comprising of shape memory polyurethane (SMPU) and cellulose nanowhisker (CNW). Water vapor permeability and sweat absorption properties were investigated under different temperature or relative humidity values to test smart comfort capabilities of the treated fabrics. Besides, felting shrinkage and weight loss of the fabrics after repeated washing cycles were investigated for end use performance. It was found out that the wool fabrics functionalized by nanocomposite treatments exhibited dynamic breathability and sweat absorption changing with temperature and relative humidity of body or environment. Moreover, nanocomposite application enhanced rigidity, tear strength, anti‐felting and weight loss performances of the wool fabric. 20 wt% CNW concentration can be suggested for thermal comfort, mechanical and end use performance enhancements to obtain smart garments having dynamic responsiveness to both body physiological and environmental changes. © 2019 Wiley Periodicals, Inc.

Wool fabrics having temperature sensitive shape memory effect were fabricated by using a shape memory polyurethane (SMPU) treatment. The contribution of SMPU treatment on bagging recovery and felting shrinkage, crucial properties for end use performance, was investigated by a test procedure including hot water conditions simulating laundry of garments according to the Woolmark TM31 standard. Chemical and morphological analyses, bending rigidity, and tear strength tests were also carried out to determine the effects of SMPU treatment on performance properties. SMPU treatment significantly increased weight and rigidity of fabrics. Most notably, SMPU treated wool fabric exhibited excellent temperature sensitive bagging recovery stimulated by a washing procedure. Also, anti-felting and weight loss performances were quite high compared to raw and commercial polyurethane-treated fabrics.

Bio‐based waste from households and industries is a big problem for the world, however, turning it into valuable composite materials can offer a promising approach to deal with it. It involves the conversion of waste from different bio‐based sources such as cellulose waste from farming and forestry leftovers, chitin waste from seafood and mushrooms, and keratin waste from hair, nails, and feathers into natural fibers. These fibers are then effectively mixed with other materials to create composite materials having unique properties, such as high strength and stiffness, good thermal and electrical conductivity, and better barrier properties. Developing these materials is not just good for the environment because it reduces landfill waste and the reliance on non‐renewable resources, but it can also make economic sense for producers. In this review, the basic compounds of natural fibers and the development of composite materials from them are explored and discussed in detail. Furthermore, their chemical and mechanical properties are discussed and summarized. In the final section, a brief overview of the challenges and the future research needed in this fast‐evolving field is given.
