Abstract: A long-lasting water-repellent textile treatment process using a curable polydimethylsiloxane (PDMS)-containing polyurethane (PU) system includes the steps of mixing a di-isocyanate with a PDMS-containing material, and reacting the di-isocyanate with the PDMS-containing material to form an NCO-terminated PDMS-containing PU system. The treatment process obtains a long-lasting water-repellent textile, which overcomes the shortcomings in hand feel, washing durability, and breathability of the conventional water-repellent textile, while having the advantages of low cost and of being an environmentally friendly process, while also providing useful and practical industrial applications.

Abstract: A long-lasting water-repellency textile application that uses a polydimethylsiloxane (PDMS)-containing polyurethane (PU) involves a manufacturing process of NCO-terminated PU prepolymer of PDMS diols and polyisocyanate with a catalyst for forming a moisture-curable PDMS-containing PU oligomer, or becoming an UV-curable PDMS-containing PU oligomer after a chemical reaction takes place. The PU oligomer owns PDMS moiety with water-repellent properties. The moisture- or UV-curable PU with NCO and acrylate end-groups can create cross-linked polymeric networks between fibers of textiles by exposing to the air or UV-radiation. The final cross-linked PDMS-containing PU treated textile demonstrates long-lasting water-repellent properties with an excellent soft hand feel and a breathable feature. Furthermore, the textile water-repellent treatment is cost-effective, and most importantly these two different curing processes could be carried out at ambient temperature without requiring any waste water discharge.

Abstract: Self-polymerization of mono-aziridine (or azetidine) and multi-aziridine (or azetidine) containing compounds with vinyl group containing organic acid, such as acrylic acid (AA), 2-methylenesuccinic acid, 2,3-dimethylenesuccinic acid and etc, at ambient temperature results in the new type of cross-linked and linear type copolymers, respectively. The polymerization of multi-functional aziridine (or azetidine) containing compounds with vinyl group containing organic acid results in the formation of high cross-linked polymers. The self-polymerization takes place at ambient temperature and the resultants, cross-linked polymeric networked materials, are solvent insoluble and potential for adhesive, composite matrix and other applications. These insoluble materials are hydrolyzed in an acidic or basic condition to form the water soluble ?-amino acids.

Abstract: A manufacturing method for ambient temperature self-curable system of water borne based polymeric ink is disclosed by using a carboxyl group containing water borne-based polymer as a base of polymeric dye and reacting the isocyanate or epoxy group of this polymer with dye to form a water borne-based polymeric dye, then neutralizing this water borne-based polymeric dye to form a water borne polymeric dye dispersion, adding a latent curing agent to get a single-pack ambient temperature self-curable system of water borne polymeric ink.
