Patent number: 11846065Abstract: A new method of delivering more precise amounts of carpet mill dye to regions of discoloration using a roller-ball applicator enables precisely metered delivery of the three primary dye colors to discolored carpet fibers. The method eliminates the need for a water extraction, enables the restoration of a more uniform color pattern, and eliminates dye overspray outside of the treated region that is inherent with the use of a spray bottle. The applicator is held with a loose grip and the roller ball is alternately moved in clockwise and counter-clockwise directions while in contact with the carpet fibers to be dyed. This ensures that dye is delivered to all sides of the fiber. To ensure even dye penetration and improved motion of the roller ball, an emulsifier is added to the dye solution. After each application, a microfilament cloth is wiped across the treated region.Type: GrantFiled: August 19, 2020Date of Patent: December 19, 2023Inventor: Jerry Gordon Roper

Patent number: 11781265Abstract: This invention relates to a method for dyeing fabrics, yarns and fibers using microorganisms whereby the adsorption of dye-containing microorganisms onto textile fibers is improved using carbon sources above a threshold concentration. Dye molecules contained within the microorganism are released from the microorganism and fixed directly and locally to the textile fibers using a heat treatment step. Said heat treatment also deactivates the carrier microorganisms. Single or multiple microorganism species, and single or multiple dyes produced by said single or multiple microorganism species may create a variety of textile colors. Suitable synthetic dyes may also be added before, during or after microorganisms have produced dyes but before the dye-releasing heat treatment step.Type: GrantFiled: July 22, 2021Date of Patent: October 10, 2023Assignee: Colorifix LimitedInventors: David Glen Hastie Nugent, Orr Yarkoni, James Ajioka

Patent number: 11739390Abstract: A tanning agent-free leather making method is provided. A raw hide is subjected to controllable dehydration with a molecular sieve-polar organic solvent composite dehydration media to achieve a dehydrated hide, and then a tanning agent-free leather is prepared by increasing the surface roughness of the dehydrated hide and reducing the surface energy of the dehydrated hide. The present disclosure does not use any metal or non-metal tanning agent, which is eco-friendly. The present disclosure breaks the balance of water distribution between the raw hide and the polar organic solvent, which realizes a multi-medium self-driven directional controllable dehydration of the raw hide, effectively solving the problems during dehydration of the raw hide only using polar organic solvent. The molecular sieve-polar organic solvent dehydration system is easy to recover and can be recycled for the controllable dehydration of the raw hide multiple times. Therefore, a brand-new clean leather making technology is provided.Type: GrantFiled: August 31, 2022Date of Patent: August 29, 2023Assignee: SICHUAN UNIVERSITYInventors: Xin Huang, Yawen Huang, Bi Shi
