Abstract:
The present invention relates to a method of applying dye and stainblocker to a substrate comprising cationically dyeable fibers which reduces or eliminates the need for subsequent reapplication of dye. The present invention solves the problem of cationic dye removal resulting from stainblocker application by providing a method wherein application of stainblocker precedes the application of dye to a substrate comprising cationically dyeable fibers. Surprisingly, the invention provides a method wherein the effectiveness of cationic dye application is improved when preceded by stainblocker application compared to stainblocker application preceded by cationic dye application. The substrate comprising cationically dyeable fibers preferably further comprises acid dyeable fibers wherein even more preferably, said cationically dyeable fibers and acid dyeable fibers are attached to a backing to form a carpet.
Abstract:
A method of treating articles having a textile surface (such as broadloom carpets or carpet tiles) with a stainblocker composition is disclosed.A pile surface structure having pile elements containing nylon yarns having both acid dyeability and cationic dyeability is dyed with both acid dye and cationic dye and then passed through a hot stainblocker treatment bath and a cooling zone. Substantially the entire height of each pile element is coated with a stainblocker composition whereby the pile surface structure has a stain resistance of 9 or higher on the AATCC Red 40 Stain Scale. The resulting pile surface has good color separation and stability, and no color loss from the catatonically dyeable yarns.

Abstract:
A method of treating articles having a textile surface (such as broadloom carpets or carpet tiles) with a stainblocker composition is disclosed. After coloring, a stainblocker composition having a temperature from twenty to ninety-five degrees Celsius (20 to 95null C.) is applied. If the articles are carpet tiles, the stainblocker is applied using a flood process. The article is dried in a drying zone having a temperature in the range from seventy-five degrees Celsius to ninety-five degrees Celsius (75-95null C.) for a time sufficient to allow the stainblocker composition to react with the nylon yarn in the textile surface. Preferably, an infra-red oven is used to define the drying zone.
Abstract:
A process is provided for manufacturing a high quality cloth having a width of 150 cm or any width in which likelihood of occurrence of defects such as color shading, rub marks, wrinkles and creases due to fabric dyeing method is eliminated and color fastness is enhanced.A process for manufacturing a woven or knit fabric using yarn dyed silk comprises the steps of dyeing (step 3) sericin which covers the periphery of silk fibers and fibroin which is located inside thereof into the same color; making yarn dyed silk (step 4, 5) by doubling and twisting the dyed silk fibers; making a cloth (step 6) by weaving or knitting the yarn dyed silk; swelling (step 7) the yarn dyed silk which constitutes the cloth by dipping the cloth into hot water in a tub; and decomposing (step 8) sericin of the yarn dyed silk of the cloth with an enzyme in hot water in a tub.
Abstract:
The invention relates to modified materials based on polyacrylonitrile having amidic groups on their surface. The modification gives the material greater hydrophilic characteristics improving its comfort properties. In addition, it permits the polyacrylonitrile to be dyed also with acidic dyes thus making it possible for it to be used for the preparation of yarns mixed with natural fibres, such as wool for example. The process for their production involves treatment of the material with enzymes of the nitrile hydratasis class obtained from Brevibacterium imperiale.
Abstract:
The invention provides a process for dyeing a textile substrate comprising wool fibres, which process comprises bringing the substrate into contact with an aqueous dyebath containing an acid dyestuff or a mixture of acid dyestuffs having(a) a build-up power on wool of from 90 to 98% at pH 4.5; together with(b) a migrating ability on wool of from 25 to 40%, at pH 4.5;(a) and (b) being determined under specific conditions, in the presence of a levelling agent which is the alkoxylation product of an amine substituted by a fatty saturated or unsaturated residue, the aqueous dyebath containing a mixture of acid dyestuffs when the substrate is a wool/synthetic polyamide fibre blend.These dyestuffs give level, fast and reproducible dyeings of a high quality.
Abstract:
A process is described for manufacturing fibrous materials such as carpet yarns and textile yarns, wherein the yarns contain at least two groups of differentially dyeable nylon filaments. The fiber chemical structure of the filaments is altered so that groups of nylon filaments in the yarn have at least two distinctly different dyeability properties. Each group of nylon filaments has an anionic polymer group difference of at least 20 microequivalents per gram of polymer, thereby providing visible differences in dye uptake.
Abstract:
Levelling agents for dyeing anionic dyestuffs are constituted by diphenylene ioxide sulphones, hydroxydiphenylene oxide sulphones, diphenyl oxide sulphones, diphenyl sulphide sulphones, mixtures of these with sulphonated aromatic hydrocarbon oils, their alkali metal and ammonium salts and/or condensation products, and reaction products of these sulphones with formaldehyde or dimethylol urea; an example of dyeing with such a levelling agent is also given. The use of these levelling agents avoids stripy or ringy appearance of certain nylon yarns, especially when these are mixed with spandex type fibres.
