Example Embodiment
[0047] Example 1
[0048] An orange petal type polyester-nylon composite fiber fabric imitating velvet dyeing and finishing process includes the following steps:
[0049] (1) Open refining
[0050] Use the open-width washing machine to wash and refine the polyester and nylon composite fabric. The temperature of the six washing tanks are 55℃, 65℃, 80℃, 95℃, 80℃ and 40℃.
[0051] (2) Pre-shrinking-initial opening
[0052] In the dyeing machine cylinder, add water, Yuzhongbao, and washed and refined polyester / nylon composite cloth for 5 minutes, and then add alkali reduction accelerator, oligomer remover and liquid caustic soda in order. The temperature is increased to 100°C at a rate of 1 min and kept for 30 minutes, and then the temperature is lowered to 60°C at a rate of 2°C / min. The liquid is drained; fresh water is introduced for the first time, and the temperature is increased to 80°C at a rate of 2°C / min and kept for 10 minutes. Cool down to 60°C for draining at a rate of 2°C / min;...
Example Embodiment
[0074] Example 2
[0075] According to the fleece-like dyeing and finishing process of the polyester-nylon composite fiber fabric of Example 1, the difference from Example 1 lies in the composition of the opener, which is composed of the following components by mass percentage:
