production, the pretreatment process has a decisive influence on the final dyeing effect and the quality of the finished product.\u00a0Whether the pretreatment is sufficient and stable directly

natural wax, pectin, protein and residual oils and sizing agent in the textile processing. If these impurities are not thoroughly removed, they will seriously influence the wetting performance of fabrics and the absorption of dyes, causing dyeing defect and color difference, etc.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Common_Processes\"><\/span>Common Processes<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>At present, the relatively mature process combination is:<\/p>\n\n\n\n<p><strong>enzymatic desizing\u00a0or biological\u00a0scouring + hydrogen peroxide bleaching<\/strong>.<\/p>\n\n\n\n<p>This process can not only ensure the effect of removing impurities, but at the same time also help to reduce energy consumption,\u00a0minimize fiber damage\u00a0and improve handle of fabrics.
