Polyurea-urethane cord treatment for power transmission belt and belt
A belt with a tensile cord embedded in an elastomeric body, having a polyurea-urethane adhesive composition impregnating the cord and coating the fibers. The composition is reaction product of a polyurethane prepolymer and a diamine curative. The prepolymer is a reaction product of a compact, symmetric diisocyanate and a polyester, polyether, or polycarbonate polyol. The belt body may be of cast polyurethane, vulcanized rubber, or thermoplastic elastomer. The cord may have an adhesive overcoat.
METHODS FOR USE OF AQUEOUS POLYURETHANE DISPERSIONS AND ARTICLES MADE THEREBY
Methods for improving localized shaping and/or support functionalities, shape retention, comfort and/or stay of apparel and other fabric articles by applying an aqueous polyurethane dispersion at a selected intensity and/or at one or more selected locations of the apparel or other fabric article are provided. Apparel and other fabric articles with improved localized shaping and/or support functionalities, shape retention comfort and/or stay prepared in accordance with these methods are also provided.
Anti-pilling merino wool fabric, garments comprising thereof, and method of fabrication thereof
The present invention provides an anti-pilling wool fabric with a coating having pilling resistance and resistance to fiber loss from fabric surface. The coating is formed by a coating formulation including at least two diisocyanates, at least two catalyst, a water dispersing agent, a buffer and water, which provides a polycarbodiimide crosslinker reactive to the relative less reactive groups on polypeptide of the wool fabric and promotes crosslinking between polypeptides of the wool fabric under relatively mild processing conditions so as to enhance mechanical strength of the wool fabric whilst no significant effect of the original finish merino wool fabric and/or garment and fiber loss from fabric surface are observed, compared to conventional treatment methods on wool fabric. A corresponding coating formulation and method of fabricating the anti-pilling wool fabric are also provided. The present invention is applicable to finished wool fabric which fibers are already with colorant(s), and/or dye(s), and/or reactive dye(s).
