  • Publication number: 20230089849
    Abstract: Described are methods and systems for cationizing and dyeing a natural fiber-containing textile. The method includes a step of steam treating a textile padded with a base and cationizing agent in a defined temperature range (greater than 100° C. to less than 110° C.) and for a defined time period (1 min to 10 min). The cationizing agent in the presence of the base is capable of generating two epoxide groups. The cationization step in the presence of steam using the halogenated catonization agent of the invention facilitates improved dyeing.

  • Publication number: 20230071562
    Abstract: Described are methods and systems for cationizing and dyeing a natural fiber-containing textile, which uses a mono- or di-quaternized cationizing agent. The method includes a step of heating the textile to a temperature in the range of 90° C. to less than 110° C. for a period of time in the range of 1 min to 10 min to react the cationizing agent with the textile. The cationization step in the presence of heat using the halogenated cationization agent of the invention facilitates improved dyeing.

  • Patent number: 10883023
    Abstract: The present disclosure provides a composition. In an embodiment an adhesive composition is provided and includes (A) a propylene-based interpolymer having a density from 0.850 g/cc to 0.900 g/cc; (B) an ethylene-based polymer composition having a melt viscosity at 140° C. from 10 mPa*s to 1,000 mPa*s; and (C) a tackifier. The composition has a molecular weight distribution ratio from 1.00 to 1.40, wherein the molecular weight distribution ratio is the molecular weight distribution of the propylene-based interpolymer of component (A) compared to the molecular weight distribution of the ethylene-based polymer composition of component (B). The composition has a density ratio from 0.93 to 1.30, wherein the density ratio is the density of the propylene-based interpolymer of component (A) compared to the density of the ethylene-based polymer composition of component (B).

  • Patent number: 10266703
    Abstract: A functionalized ethylene-based polymer dissolved in an appropriate solvent and applied to a nonpolar surface can change the surface polarity/characteristics of the nonpolar surface. This change to the surface polarity/characteristics of the nonpolar surface allows adhesion of materials, such as paint, to surfaces such as polypropylene, polyethylene and polyolefin elastomers.
