A welding process may be configured to convert a substrate comprised of short staple fibers into a welded substrate having significantly increased strength as compared to the raw substrate. When applied to a one-dimensional substrate, such as a yarn, the welding process may also reduce the diameter of the welded substrate compared to that of the raw substrate. Additionally, the welding process may be configured to impart superior color properties to the welded substrate compared to the color properties of the raw substrate, which superior color properties may be very pronounced when performing a welding process on a raw substrate comprised of colored and/or dyed recycled fibers.

An ink jet ink composition for textile printing contains a crosslinking component having a blocked isocyanate group, tertiary amine, at least one carboxylic acid selected from the group consisting of monocarboxylic acid, dicarboxylic acid, and tricarboxylic acid, a pigment, and water.

A composition for aqueous ink contains water and a coloring material, wherein the calcium ion content x (ppm) and the oxalate ion content y (ppm) in the composition for aqueous ink jet satisfy the relation of y?3491.8x.sup.?3.386.

A required portion of a textile fiber product is subjected to a fiber-modifying treatment by applying a fiber-modifying agent containing at least an aqueous polyvalent cationic salt solution and a urethane resin having a blocked isocyanate group at the end thereof, after which a masking ink containing at least a white or light-colored pigment, a water-soluble polymer dispersing agent, a self-emulsifying urethane resin and/or an acrylic resin having an acid value of 40 to 100 mg KOH/g, and an aqueous liquid as a solvent or disperse medium, is printed by an inkjet process.

The present invention falls within the field of textile products, and specifically provides a brand new production method for a high-low pile towel. The method breaks through the visual monotony of conventional towels and a traditional design method in which two or three adjacent conventional pile loops have a consistent pile loop height in conventional high-low pile towels, but uses a design method in which two or three adjacent pile loops have a inconsistent pile loop height for weaving, and at the same time uses a special dyeing and finishing treatment, whereby the dyed and finished product has a special visual effect, a strong visual impact, and a fluffy and soft hand feel, and the product therefrom has a high additional value without improving the coats, compared with the existing products. The method fills up a blank of high-low pile towels, and can be widely popularized and applied.

An ink jet ink composition for textile printing including a dye and 5% to 30% by mass of a cyclic amide that is liquid at normal temperature and that has a normal boiling point in the range of 190 C. to 260 C., wherein the hue angle h defined by the CIELAB color space on a recording medium ranges from 15 to 80 degrees.

An ink jet ink composition for textile printing including a dye containing copper or chromium and 5% to 30% by mass of a cyclic amide that is liquid at normal temperature and that has a normal boiling point in the range of 190 C. to 260 C., wherein the hue angle h defined by the CIELAB color space on a recording medium ranges from 260 to 310 degrees.

A dye additive suitable for use in improving the dyeing of aramid fibers includes non-water components dissolved in water. The non-water components include about 20-25% (w/w) sodium or potassium nitrate; about 20-25% (w/w) ketone solvent; about 30-40% (w/w) aromatic solvent; about 1-5% (w/w) of each of glycol ether, biodegradable solvent, acetic acid 56% strength or equivalent or equivalent amount of formic acid, brine salt, sodium or potassium hydroxide, and phenylenediamine, about 1-10% (w/w) of each of a strong acid, hydroxycarboxylic acid, and lanolin; wherein the water makes up about 50-70% of the weight of the dye additive and the non-water components make up about 30-50% of the dye additive. The dye additive may be added to a dye bath at a w/w percentage of about 0.25% to about 6%.

The present invention relates to a method for reducing or preventing the decomposition of a composition Z comprising Z1 a salt of dithionous acid in an amount ranging from 50 to 100 wt % and optionally Z2 an additive selected from the group consisting of alkali metal carbonate, alkaline earth metal carbonate, alkali metal or alkaline earth metal tripolyphosphate (Na.sub.5P.sub.3O.sub.10), alkali metal or alkaline earth metal sulfite, disulfite or sulfate, dextrose and complexing agents in a combined amount ranging from 0.0001 to 40 wt %, which comprises contacting the components Z1 and optionally Z2 in the solid and/or dry or solvent-dissolved or -suspended state with at least one of the following compounds V in the solid and/or dry or solvent-dissolved or -suspended state, wherein the compounds V are selected from the group consisting of: (a) oxides of the alkali metals lithium, sodium, potassium, rubidium, cesium, or of magnesium, (b) sodium tetrahydroborate (NaBH.sub.4), (c) anhydrous copper(II) sulfate (Cu(SO.sub.4)), phosphorus pentoxide and (d) basic amino acids arginine, lysine, histidine, wherein the solvent for Z1, optionally Z2 and V is practically water-free.

A ring dyed textile product resulting from the treatment of yarn, fabric, or garments with a combination of a dye, engineered polymer, and heat. The resulting material can be engineered into fabric, garments, or other textile product. Subsequent abrasion of the article can produce apparel in a broad color range that has an aesthetic appearance similar to that of garments produced from indigo dyed yarn. Colorfastness performance including crocking, washfastness, and lightfastness are good to excellent for a broad color range.
