Embodiment
[0025] A modified cellulose fiber dyeing process mainly comprises the following steps:
[0026] 1. Production control process
[0027] 1. Gray cloth storage - order recording (various physical and chemical indicators required by the customer) - order review - production process card - fabric preparation - blank finalization - cutting board re-sampling - pre-treatment scouring - dyeing - soaping - opening width rolling - Finished product finalization (adding hydrophilic softness, citric acid) - Finished product inspection and packaging storage;
[0028] Order review: each order is not the same batch, and each color sample test is required to determine the process before entering production.
[0029] 2. Key process of dyeing and finishing
[0030] 1. Test the sample according to the standard process, check the pH value of the process steps, and record it. If there is a difference and there is residual liquid, it proves that the formula is excessive and needs to be adjusted and...
