Merino Staining Process Utilizing Aqueous Nitrate at a fairly low Temperatures

Because they are a non-fluid medium, fluid smelling salts give water a number of real qualities, like a low subatomic weight and a high porousness.Through ecological processing, it has been widely used to improve the luster, softness, and dyeing properties of cellulosic fibers.However, not many people have reported using liquid ammonia to dye treated wool, particularly at lower temperatures.Before dyeing the wool using a standard wool dyeing machine, in this instance, a continuous liquid ammonia finishing machine was used to batch process the wool.By dissolving the disulfide bonds between cystines, the treatment with liquid ammonia made it simpler for dyestuff to enter the fiber. As a result, scale flakes and cuticle cracks developed on the fiber surface.In addition, the dyeing temperature could be reduced to 85 °C with only a 3–5% decrease in fiber strength, and wool dyed with Lanaset and Lanasol CE dyes had higher uptakes and K/S values than untreated wool.Chemical auxiliaries from Miralan LTD, on the other hand, can lower the dyeing temperature for reactive dyes to 70 °C and reduce fiber strength by 8 to 10%. Dyeing wool with liquid ammonia can be done at a temperature lower than boiling (100 °C), with less energy required, and with less loss of wool fiber strength.Because it makes it possible to use low-temperature dyeing technology in the industrial sector, the method is important and has a lot of value.
