Wear‐resistant cotton fabrics modified by PU coatings prepared via mist polymerization

Abstract

Cotton fabric was successfully modified using a simple mist polymerization with polyurethane (PU) prepolymer and ethylene glycol as the monomers. Scanning electron microscope showed the presence of a very thin polymer coating on the cotton fiber surface. Martindale abrasion tests revealed that the thin PU coating imparted to the cotton fabric a doubled wearing durability compared with the original fabric. Additional experiments demonstrated that the mist polymerization has little impact on the desired cotton properties such as water absorptivity, vapor transmissibility, mechanical property, and flexibility. Considering the excellent balance between the enhanced abrasion resistance and the cotton natures, this surface modification methodology has potential to fabricate wearing durable textiles.

Effect of coating process on morphology, bending rigidity and wearability of polyester harness cords

“…The wearability of harness cord is mainly affected by properties of fibers, structure, surface coating, lubricant and interfacial property [3,4]. The traditional cotton and ramie harness cords are inferior in wearability and are susceptible to environments; thus, they need to be lubricated, waxed or sized [5][6][7]. The vinylon harness cord is sensitive to environmental humidity due to its high moisture regain.…”

UV-Cured Fluoride-Free Polyurethane Functionalized Textile with pH-Induced Switchable Superhydrophobicity and Underwater Superoleophobicity for Controllable Oil/Water Separation

“…PU coatings have excellent wearing durability, are safe to the human body, and are well suited for fabrics or textiles. , Moreover, UV-curing PU coatings may possess many other advantages, such as energy and time savings, low environmental impact, and very fast and efficient polymerization. , In addition, due to the nanoscale cage structure of polyhedral oligomeric silsesquioxane (POSS), the introduction of POSS into the polymer main chains at the molecular level for the construction of organic/inorganic hybrid materials is a good strategy to acquire high performance materials, which can improve the hybrid material performance, such as surface performances, mechanical properties, thermal stability, and biological function.…”

Excellent binding effect ofl-methionine for immobilizing silver nanoparticles onto cotton fabrics to improve the antibacterial durability against washing

“…[1][2][3] To extend its market share, various efforts have been made to endow cotton textiles with additional functions, [4][5][6] and such exploration has gradually concentrated on a few areas, for example, antibacterial effects, 7,8 UV-protection, 9,10 hydrophobic coating, 11,12 ame retardance, [13][14][15] and wear-resistance. 16 Among these functions, the antibacterial effect has received more signicant attention because the bacterial problem of cotton textiles oen seriously troubles users. The temperature, moisture, and nutrients in the cotton textiles generally meet the requirements for the growth and reproduction of a multitude of bacteria and fungi, 17 and the microorganisms living on cotton fabrics oen produce terrible odours, and cause colour degradation and even serious risks to human health.…”
