A temperature-regulating fiber may include a spun phase change polymeric material that may include a plurality of phase change polymer blocks. The fiber may have a fixity ratio of at least 80% and a recovery ratio of at least 74%.
摘要:
A finishing liquid which containing as least one kind of dendrimer molecules with terminal groups of —NH2, —OH, —COOH, —COOR, —R, —Si—O—R, PAMAM-OS, —R-halogen etc, or with groups which can be modified to achieve the above groups was invented. Employing sol-gel or solution method, the finished textiles obtain part of the following multifunction: breathable, water proof, oil repellency, soil repellency, anti-static, anti-UV irradiation, anti-bacterial, dying acceleration, and slowly release of drug and perfume.
摘要:
The present invention relates to methods for synthesizing shape memory polyurethanes, and fibers therefrom. The polyurethanes can be synthesized via solution polymerization or bulk polymerization. Following synthesis, the polyurethanes can be treated via wet spinning, dry spinning, reaction spinning, melt spinning, or electro spinning.

摘要:
A reaction system for forming a viscoelastic polyurethane foam includes an isocyanate component and an isocyanate-reactive component that includes at least a polyol component, an additive component, and a preformed aqueous polymer dispersant. The mixture includes 50.0 wt % to 99.8 wt % of the polyol component, 0.1 wt % to 49.9 wt % of the additive component, and 0.1 wt % to 6.0 wt % of the preformed aqueous polymer dispersant. The aqueous polymer dispersant has a pH from 6.0 to 12.0 and includes from 5 wt % to 60 wt % of a polymeric component and from 40 wt % to 95 wt % of a fluid medium. The polymeric component includes at least one base polymer derived from 20 wt % to 100 wt % of at least one hydrophilic acid monomer having at least one carbonyl group, phosphate group, phosphonate group, or sulfonyl group, and optionally derived from at least one hydrophobic terminally unsaturated hydrocarbon monomer.
