Parameters
This low-temperature refining agent has strong oil removal and penetration refining effects, and has excellent removal capabilities for lignin, ash, and cotton seed shells in cotton fibers.
1. The combined treatment of the two ensures the whiteness and brightness of bleached fabric bases, providing a good guarantee for the vividness of dyeing and coloring as well as the dyeing rate.
2. As it is treated at 85℃, the heating time is shortened, the steam usage is reduced, especially for certain factories with insufficient steam supply, it can effectively complete the pre-treatment process before production quickly, facilitating production operations.
3. As it is treated at 85℃, for varieties prone to creasing, it avoids the creasing stage during temperature rise and drop, and controls the creasing easily within the range of 85℃ - 60℃, significantly reducing the chance of creasing.
4. The low-temperature 85℃ pre-treatment for products containing spandex, under mild wet heat conditions, the strength of spandex does not decrease significantly, and the overall strength of the fabric is guaranteed. Compared with the conventional high-temperature 100℃ * 60min process, it can maintain an effect of reducing strength by 30-50N.
5. The low-temperature 85℃ pre-treatment has a mild production condition, short process time, and reduces the loss of cotton fibers during production processing, facilitating the guarantee of a low loss rate of the product during the processing.
Product Description
Pre-treatment process plan
In response to the current trend of energy conservation and emission reduction in environmental protection, in order to further improve and optimize the pre-treatment processing scheme of cellulose fibers, especially in the processing of T/C, CVC cotton and other products containing spandex, considering factors such as the significant decrease in product burst strength due to the needle structure of the product and the wet-heat strength reduction of the spandex fibers, the 85°C pre-treatment and bleaching process with low-temperature scouring agent is implemented to ensure the whiteness and luster of the product while shortening the processing time, reducing the chance of strength decline, creases and scratches, etc. The specific process is as follows:
1. Dark-colored varieties:
Sodium hydroxide 1.0%
Low-temperature refining agent 2.0%
H2O2 (27.5%) 6-8%
Process conditions: 85°C * 60 minutes
2. Light and bright-colored varieties:
Sodium hydroxide 1.0%
Low-temperature refining agent 2.0%
H2O2 (27.5%) 8-10%
Process conditions: 85°C * 60 minutes
3. White varieties:
Sodium hydroxide 1.0% (the specific dosage is adjusted according to the whiteness requirements)
Low-temperature refining agent 2.0%
H2O2 (27.5%) 12%
Process conditions: 85°C * 60 minutes
Note: The dosage of other additives should be calculated based on the actual bath ratio; when the bath ratio is less than 8, the dosage of additives should be calculated according to OWF; when the bath ratio is 8 or above, the dosage of additives can be calculated based on concentration in G/L. Specific adjustments can be made based on the actual application effect of the bulk goods.
