A multispectral camouflage fabric having a camouflage pattern containing a least a first, second, and third color. Each of the first, second, and third colors contain at least one dye and at least one of the first, second, and third colors contains carbon black. The camouflage pattern has a short wave infrared (SWIR) reflectance pattern and contains first, second, and third reflectance zones. Each reflectance zone has an upper and lower reflectance zone boundary and the difference between the upper and lower first reflectance zone boundaries is approximately 10 percentage points. The difference between the first and second zone and the second and third zone is approximately 10 percentage points. At essentially all wavelengths within the SWIR portion of the spectrum, the first color falls within the first zone boundaries, the second color falls within the second zone boundaries, and the third color falls within the third zone boundaries.

In one aspect, a composition for treating fibers comprises an acidic aqueous or aqueous-based continuous phase and a liquid repellent phase comprising a dendrimer component and/or non-dendrimer alkyl urethane. The treatment composition, for example, can have pH of 2.5 to 6.5. In some embodiments, carboxylic acid is employed in the treatment composition for providing the acidic character of the aqueous or aqueous-based continuous phase. Moreover, the treatment composition can further comprise at least one of an acid stain resist component and soil release component. In some embodiments, fibers treated with compositions described herein exhibit ionic character.

A dye composition and a dyeing method for an elastic fabric are provided. The dyeing method includes: (a) providing an elastic fabric which includes an elastic fiber; and (b) immersing the elastic fabric in a dye composition. The dye composition includes an ion modifier and a dye. The elastic fiber of the elastic fabric has a first ion by contacting the ion modifier, and the first ion has a first charge; the dye has a second ion, and the second ion has a second charge opposite to the first charge. The first ion of the elastic fiber and the second ion of the dye together form an iconic bonding.

A polymeric linear substrate is provided with one or more active agents infused into the linear material to a depth less than the 100 micrometers, optionally where the polymeric linear substrate has a cross sectional dimension that does not exceed 2 centimeters. The polymeric material may include a polyamide, a polyester, polyvinylchloride, or polycarbonate. Also provided are systems for infusing a linear substrate with one or more active agents that includes a dye supply providing a dye; a process tank connected to the dye supply and providing a reservoir of a liquid infusion solution including the dye through the linear substrate infusion system; and a process chamber fluidly connected to the process tank for contacting the liquid infusion solution with a linear substrate effective to infuse the dye into a surface of the linear substrate.

A method of forming an active agent infused linear material includes passing a substantially linear polymeric substrate through a linear substrate infusion chamber in a first direction, flowing a liquid infusion solution through the linear substrate infusion chamber in a second direction, and contacting the linear substrate with the liquid infusion solution at an infusion temperature and for an infusion time effective to infuse the one or more active molecules into or onto a surface of the linear substrate, thereby forming an active agent infused linear material. The liquid infusion solution includes one or more active molecules. The second direction is substantially opposite or substantially parallel to the first direction. A linear substrate infusion system and a polymeric linear substrate are also disclosed.

A method for dyeing artificial fibers comprises preparing an artificial fiber, and adding a dyestuff, a crosslinking agent, and an appropriate amount of water into a tank for mixture. Then, the artificial fiber is immersed in the tank to obtain a dyed artificial fiber, and the dyed artificial fiber is pressed by a roller set. Finally, the dyed artificial fiber is dried out.

Apparatuses and processes for producing yarn having longitudinally variable dye uptake and well as yarns having longitudinally variable dye uptake and articles prepared from these yarns are provided.

A dyeing process includes weaving patterns on a textile of nylon, CD yarn and polyester; pouring acidic dye, cationic dye and dispersive dye into a dyeing machine; adding auxiliary coloring agent, homogeneous coloring agent and coloring retardant into the dyeing machine wherein the auxiliary coloring agent is prepared by adding 1 g of acetic acid to 1 liter of water to form a solution which is adjusted to have a pH between 4 and 5; the homogeneous coloring agent is prepared by adding 1 g of homogeneous coloring agent to 0.1 kg of textile; and the color retardant is prepared by adding 1 g of sodium sulfate to 1,000 g of water; putting the textile in the dyeing machine to dye as a finished textile. Each pattern woven by a different textile material has a color corresponding to the applied dye. The color of patterns is the color of the dye applied to the patterns.

The invention relates to carpets comprising a cationically-dyeable polyester effect yarn, dyed with a basic dye, and a background polyester or polyamide yarn, not dyed with a basic dye, and wherein the carpet has been overdyed with a disperse dye or an acid dye. The invention further relates to methods of preparing such overdyed carpets.
