摘要:
The present invention provides a process for improving the colorfastness, ozonefastness, and stainresistance of cationic dyeable nylon fibers dyed with basic dyestuffs wherein the process comprises the steps of treating the nylon fibers with a tannic acid product and then fixing the treated nylon fibers by a fixation method.
摘要:
Flame resistant stretch fabrics made from aramid fibers and elastomeric fibers and methods and systems for dyeing such fabrics while significantly retaining the stretch properties of the fabrics. Such methods and systems include the use of certain dye carriers not conventionally used in the aramid dyeing process that enable the fabric to be dyed under normal aramid dyeing conditions without eliminating or significantly impacting the stretch properties of the fabric. Such suitable dye carriers for use in the process include, but are not limited to, benzyl alcohol, butyl benzoate, n-butyl phthalimide, isopropyl phthalimide, dimethyl phthalate, biphenyl, monochlorotoluene, and combinations thereof. Phthalimides, and more particularly blends of n-butyl phthalimide and isopropyl phthalimide, have proven particularly effective at dyeing the aramid fibers at high temperatures while retaining the elastomeric properties of the fabric. The dyed flame resistant stretch fabrics of this invention can be used to construct, among other things, the entirety or various portions of, a variety of protective garments for protecting the wearer against electrical arc flash and flames, including, but not limited to, coveralls, jumpsuits, shirts, jackets, vests, and trousers.
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 95° 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 (75-95° 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.

An iridescent effect is achieved in satin weave filling-faced fabric using sheath-core filaments wherein the core is dyed to a color that is different from that of the sheath.
摘要:
There is provided by this invention a process for preparing poly(paraphenylene terephthalamide) fibers dyeable with cationic dyes. The process comprises soaking poly(paraphenylene terephthalamide) fibers in sulfuric acid, washing the fibers and dipping the acid soaked fibers or never-dried PPD-T fibers in an aqueous solution of a dye promoting species. The fibers can then be dried and subsequently dyed.
