Abstract
Performance textiles that protect human from different threats and dangers from environment are in high demand, and the advancement in functionalization technology together with employing advanced materials have made this an area of research focus. In this work, silicone rubber and environmentally friendly fluoropolymers have been employed to explore superomniphobic surface on cotton fabrics without compromising comfort much. It has been found that a cross-linked network between the rubber membrane and the fluoropolymers has been formed. The surface appearance, morphology, handle, thickness and chemical components of the surface of cotton fabrics have been changed. The coated fabrics showed resistance to water, aqueous liquid, oil, chemicals and soil. The comfort of the coated fabrics is different to uncoated cotton fabrics due to the existence of coated layers on the surface of cotton fabrics. This work would benefit the development and design of the next generation of performance textiles with balanced performance and comfort.
Highlights
Protective clothing has been developed to help humans withstand hazards and threats from environment or other sources [1,2]
A three-layer coating was added on the surface of cotton fabrics followed by a curing process to initiate the crosslinking between the layers, as illustrated in Figure 2a the mechanism of the coating
The air permeability of cotton fabrics has been affected after coating, as the results show in
Summary
Protective clothing has been developed to help humans withstand hazards and threats from environment (cold, hot, wind, water, soil, gas, etc.) or other sources (fire, explosion, corrosive chemicals, pollution, etc.) [1,2]. Protective clothing with a single function, such as being flame retardant [3,4], water repellent/superhydrophobic [5], oil repellent [6], self-cleaning [7], or with cold protection [8], chemical protection [7] and moisture management, has been widely developed to serve customers in different areas [3,9]. The development of new fibers and/or the functionalization of current fibers are the pathways to advance technology towards the generation of performance textiles. Much attention has been put on the functionalization of fabric surface for the development of performance textiles, and different technologies have been developed including plasma-enhanced chemical vapor deposition [16], plasma [17], grafting [18] and coating [19]
