Embodiment 1
[0012] The sample specifications of lyocell, cotton and spun silk fabrics are: lyocell 20X spun silk 15 / cotton 85 30 116X78 +57 / 58, and the weight is 252g / ㎡. The above samples are dyed and finished by the following steps:
[0013] Pre-treatment: including desizing, scouring, bleaching and other processes: desizing adopts enzyme oxygen cold stack process, in desizing, add 2000L 10g of desizing enzyme per liter of water, 2g of chelating dispersant cm-5, wax remover WR is 4 g, refining agent 88ECO is 4 g; in the bleaching process, 5.5 g of 100% hydrogen peroxide and 7 g of stabilizer are added per liter of water.
[0014] Dyeing: The specific operation is: add water according to the bath ratio of 1:4-5 of the weight of the lyocell fiber to be dyed and the weight of the cotton and spun silk blended fabric, put the fabric into operation for 3 minutes, and then add neutral fixation at a temperature of 40°C Alkali-free reactive dyes—Kayacelon React dyes produced by Nippon Kayaku and ...
Embodiment 2
[0019] In the pretreatment process, add 2000L 9g of desizing enzyme per liter of water during desizing, 2.5g of chelating dispersant cm-5, 3g of wax remover WR, and 5g of refining agent 88ECO; in the bleaching process, add 100 % hydrogen peroxide 6 g, stabilizer 8 g.
[0020] All the other are with embodiment 1.
Embodiment 3
[0022] In the pre-treatment process, add 2000L 11g of desizing enzyme per liter of water, 1.5g of chelating dispersant cm-5, 5g of wax remover WR, and 3 g of refining agent 88ECO; in the bleaching process, add 100 % hydrogen peroxide 5.7 g, stabilizer 6 g.
[0023] All the other are with embodiment 1.
