摘要:
A TBET cassette including at least one xanthine -or pyronin- based compound as a donor or acceptor is disclosed. Also, a method of TBET cassette design in which four criteria may be used is provided. TBET cassettes may be used to label biological molecules, in clothing dyes, and in cosmetics.
摘要:
Bi-constituent fiber having a cationic dyeable nylon, usually Type 6 nylon adequately sulfonated, as the major component with an intimate melt blent of a minor amount of a polyester are dyed with a anionic dye to improve lighfastness, ozone resistance and to provide resistance to acid-type stains. The fibers may be tufted into carpets that are resistant to acid-type stains. Both components of the bi-constituent fiber may come from recycled sources so that 100% of the fiber, excluding processing additives, is based on post consumer recycled polymer.
摘要:
The present invention is directed to a method, apparatus, and system for color management by a retailer. The method, for example, includes comprising the steps of: choosing an engineered color standard (ECS); communicating the ECS to a product vendor; having a product produced using the ECS; and controlling the product's color quality by comparing the ECS to the produced product. The ECS preferably comprises reflectance data and a dye specification.
摘要:
A textile substrate (252) is patterned by the selective application of various dyes to the substrate surface in a way that provides desirable, visually apparent enhancements in the area of pattern detail, definition, and color range (70), through the use of a novel patterning system (254), including the application of various chemical agents, that makes such enhancements possible. In one embodiment, the patterning system (254) described herein is capable of producing pile-faced textile substrates (252), useful as floor coverings, that exhibit a unique combination of desirable pattern attributes that have been identified and measured using novel techniques specifically developed for these substrates and pattern attributes.
摘要:
The invention relates to the use of malonaldehyde derivatives of formula (I) for dyeing fibres containing keratin, in the presence of at least one compound with a primary or secondary amino group or hydroxy group chosen from primary or secondary aliphatic or aromatic amines, nitrogenous heterocyclic compounds, alpha - to omega -amino acids, oligopeptides made up of 2 to 9 amino acids and aromatic hydroxy compounds and/or at least one CH-active compound. R and R each represent a (C1-C4)-alkyl group independently of each other, and R represents a hydrogen atom, a halogen atom, a (C1-C4)-alkyl group, a (C1-C4)-alkoxy group, a hydroxy-(C1-C4)-alkoxy group or an optionally substituted aryl or heteroaryl group, each pair of radicals being able to form a 5-, 6- or 7-ring.
摘要:
A dyed substrate having at least one dyed surface. At least one dye solution is disposed across at least a portion of the surface in combination with a migration promoting composition and/or a migration limiting composition. The migration promoting composition and/or migration limiting composition adjusts the migration of at least a portion of the dye solution across the substrate in a controlled manner. Dye migration may be arrested by the application of RF (radio frequency) energy as a step in dye fixation. A process for forming the dyed substrate is also provided.
