摘要： By forming a meta-type wholly aromatic polyamide fiber using a highly hydrophobic UV absorber and having specific physical properties, a meta-type wholly aromatic polyamide fiber having light resistance, which can be dyed in various hues by carrier dyeing and in which the shedding of a light stabilizer during dyeing can be suppressed, is provided. That is, the meta-type wholly aromatic polyamide fiber contains a UV absorber with a water solubility of less than 0.04 mg/L and has a degree of dye exhaustion of 90% or more in the form of a dyed fiber and a light resistance retention of 80% or more after carrier dyeing.

摘要： There is provided a process of dyeing yarn or cloth comprising fibres, comprising dyeing at least part of the fibres with at least two types of dyestuff that dye the same fibres substantially the same colour. One of the types of dyestuff chemically bonds with or is at least partially incorporated into the fibre structure and the other type of dyestuff does not chemically bond with or become at least partially incorporated into the fibre structure.

摘要： 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.

摘要： 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.

摘要： 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.
