Want to learn more about mercerizing?
The first decision that must be made in the mercerizing process of fabrics is to select the fabric to be mercerized in the original embryo, pre-processed, or partially pre-processed state. Regarding the choice of whether materials need pre-processing before the mercerizing project, it depends on the type of materials, special plant equipment, and the demand for mercerized fabric products. Theoretically, for most factories, if it is to mercerize the original embryo, its operation should be the simplest, because it can save drying or special pre-treatment. However, since a large amount of impurities are brought into the lye, these impurities will hinder the mercerizing process or the recovery of lye. However, under ideal circumstances, the original embryo will show satisfactory gloss and affinity for dyes after mercerizing treatment, and will enhance the toughness (Strength) and other excellent properties. Therefore, in order to obtain satisfactory results in the mercerizing process of the original embryo, a strong penetrant must be added to the lye.
The mercerization of the original embryo or the desizing treatment of the original embryo or the mercerization of the refined cotton, their respective gloss, toughness, chemical activity and affinity for dyes, cannot help us choose the advantages and disadvantages. This choice can only be made after a rigorous evaluation of the convenience of the manufacturing machine, the effectiveness of the lye recovery equipment and the drying equipment. Before the mercerizing process, the material may have been completely refined and bleached and there are many manufacturing machines to operate with this equipment. Generally speaking, assuming that all mercerizing processes are controlled under the best conditions, the mercerizing process after scouring and bleaching of the material will show a better gloss and smoother appearance than the bleached material before mercerizing process. The mercerizing treatment of bleached materials has a possible shortcoming, that is, the adverse effects of excessive bleaching will not be manifested under normal circumstances, but will be manifested after the mercerizing treatment of the materials. Any excessively bleached fiber will be dissolved a little in the lye, and a certain degree of tensile strength will be destroyed.
Generally speaking, different mercerizing pretreatments will not cause too much difference between products. If the main purpose of mercerizing is excellent gloss and smoothness, then the pretreatment of bleaching is of course the best. If the maximum tensile strength must be maintained, then bleaching should be carried out after mercerizing.
