摘要:
A textile is disclosed having regions of color contrast and corresponding regions of sculptured three-dimensional surface geometry. Furthermore, one or more methods of making such a textile also are disclosed. The textile includes a first side having first regions and second regions in a predetermined pattern. The first and second regions differ in color shade values due to the etching of the textile, which has the effect of degrading or dissolving fiber material from the second regions, thereby providing a three dimensional sculpted geometry and a color contrast between etched and non-etched areas. Screen printing is applied using an extremely strong acidic or alkali composition paste upon the textile, followed by heating. Then, a washing step and a drying step results in a product having a color shade difference between etched areas and non-etched areas having differing DeltaL* color shade values using L*a*b* color space measurement techniques.

A textile (20) is disclosed having regions of color contrast and corresponding regions of sculptured three-dimensional surface geometry. Furthermore, one or more methods of making such a textile (20) also are disclosed. The textile (20) includes a first side (22) having first regions (23) and second regions (24a-c) in a predetermined pattern. The first and second regions (23 and 24a-c) differ in color shade values due to the etching of the textile (20), which has the effect of degrading or dissolving fiber material from the second regions (24a-c), thereby providing a three dimensional sculpted geometry and a color contrast between etched and non-etched areas. Screen printing is applied using an extremely strong acidic or alkali composition paste upon the textile (20), followed by heating. Then, a washing step and a drying step results in a product having a color shade difference between etched areas and non-etched areas having differing ΔL* color shade values using L*a*b* color space measurement techniques.
摘要:
The present invention is generally directed to a process for making fabrics containing cotton fibers more aesthetically pleasing and resistant to staining by anionic dyes by derivatising the cotton so that it exhibits a permanent anionic charge. By increasing the anionic charge of the fibers, the fibers become resistant to anionic coloring agents which may undesirably come into contact with the fibers. Furthermore, the negative charges repel each other resulting in a fabric with greater loft and porosity. This results in greater smoothness, better hand, and more comfort. Besides being used to prevent the cross-staining of fabrics, the present invention can also be used to make carpet materials resistant to anionic staining agents. Alternatively, it has also been discovered that an anionic derivative can be used to catalyze permanent press resins onto fabrics containing cellulosic fibers, also resulting in anionic cotton.
摘要:
In a continuous application process with post-steaming Sulfonated Aromatic Condensates (SAC) having molecular size (hydrodynamic volume) defined by elution volume (Ve) determined by Size Exclusion Chromatography (SEC) of between 6.3 and 6.5 ml. using the procedure described, are such that they are not too small so that migration into the fiber occurs (reduces ring dyeing effect) nor are they too large such that they require extremely long steaming times or the use of swelling agents to be effective. This is independent of the degree of sulfonation of the SAC.
摘要:
The invention is a process for dyeing polyamide substrates comprising anionic and cationic fibers in multicolored patterns. Cross-staining or dyeing of the cationic fibers by the anionic-dyeable nylon colorant is avoided. The anionic dyeable fiber portion is dyed with a fiber-reactive vinyl sulfone dye having one or more sulfonic acid substituents and one or more vinyl sulfone groups with the proviso that the sum of the number of sulfonic acid and vinyl sulfone substituents is at least three. The dyeing process is conducted at a pH of about 2 to about 4. Optionally the cationic portion of the substrate may be dyed with a basic dye in admixture with the vinyl sulfone dye.

Dans un procédé d'application continue par post-vaporisation, les condensats aromatiques sulfonés (CAS) ayant une taille moléculaire (volume hydrodynamique) définie par un volume d'élution (Ve) déterminé par chromatographie par exclusion de tailles (CET) compris entre 6,3 et 6,5 ml utilisant le procédé décrit, ne sont pas trop petits, de sorte que la migration jusque dans la fibre se produit (réduit l'effet de coloration annulaire), et ne sont pas trop grands, de manière à éviter des temps de vaporisation extrêmement longs, ou l'emploi d'agents gonflants, cela indépendamment du degré de sulfonation des CAS.

摘要:
A liquid buffer composition comprises either or both of monsodium phosphate, in a concentration of 13-40 percent by weight, and tripotassium phosphate, in a concentration of 20-50 percent by weight, in aqueous solution. Combination of these two ingredients provides liquid buffer mixes for use in place of solid phosphate buffers.
