Abstract: This paper highlight the most important areas and directions of shape memory polymers in textiles. The textiles of shape memory polymers involve fibre spinning (including wet-spinning, melt-spinning and electro-spinning), fabric, smart apparel, actively finishing technology and WVP investigation. Based on the molecular structure of shape memory polymer, the shape memory transformation from polymer to textiles and application theory are illustrated and stated. Additionally, the challenges of shape memory polymers in textiles are pointed out and some research directions are also suggested in this paper.

Abstract: Shape memory finishing is suitable to wool knitted and woven fabric. The chemical is water soluble and environment friendly. The shape memory treated wool knitted fabric and garments achieve good dimensional stability, pill resistance, pattern design, crease retention, wrinkle recovery and bagging recovery effects. The finishing process is simple, saving water and can be done using the normal common washing machine. Shape memory chemical is also used on cashmere finishing increasing the piling rates.

Abstract: Shape memory polymers are a promising class of stimuli-responsive materials that have dual-shape capability. This kind of materials can recover their shape in a predefined way from temporary shape to desired permanent shape when exposed to an appropriate stimulus. In the development and extensive application of synthetic shape memory polymers on textile industrials, the thermal and hygrothermal effects of wool materials have attracted considerable attention. In this article the fundamental concept of the shape memory polymers and the fundamental aspects of the shape-memory effect were reviewed. The thermal and hygrothermal effects of wool materials were also summarized to discuss the shape memory behavior of wool materials. Besides the effects of synthetic shape memory polymers on the thermal and hygrothermal of the woven wool fabrics were introduced to show the shape memory behavior of treated wool further.
