  • 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: 11420181
    Abstract: A method for suppressing the formation of ammonia comprising providing a carrier material to a container having a headspace; providing a bacteria, an acidifier and an odor inhibitor to the carrier material, the bacteria comprising Staphylococcus-xylosus or Staphylococcus-cohnii bacteria, and the odor inhibitor comprising a salt of an aminopolycarboxylic acid compound; and applying animal waste to the carrier material; wherein there is a 5 to 98 percent improvement of ammonia content in the headspace as compared to an untreated control comprising a container containing the carrier material and the bacteria and not contain the odor inhibitor.
