Embodiment
[0027] Fabric fabric: width 206cm, 216g / cm 3 .
[0028] The dyeing and finishing process of the high-elastic hemp fabric provided in this embodiment includes a pre-treatment process, a dyeing process and a setting process, and the pre-treatment process includes an open-width desizing process and a cylinder training process in sequence. , pre-setting process and loose alkali reduction process, the specific steps of the dyeing and finishing process are as follows:
[0029] (1) Pretreatment process:
[0030] In the open-width desizing process, an open-width desizing machine is used to desizing the gray fabric. The formula of the desizing aid used in the open-width desizing process is as follows:
[0031] Liquid caustic soda 45g / L,
[0032] Long car fast desizing agent TF-127HA 2g / L,
[0033] Sodium tripolyphosphate 2g / L;
[0034] The temperature conditions of the open-width desizing process are 85°C and the vehicle speed is 40m / min.
[0035] Under hot alkali conditions, com...
