In the vibrant world of textile manufacturing, achieving brilliant colors with lasting fastness is a key objective. For cotton fabrics dyed with naphthol-based dyes, a critical step in ensuring vibrant hues and preventing color bleeding is the use of a mordant. Aluminum Sulfate, readily available from reputable suppliers like NINGBO INNO PHARMCHEM CO.,LTD., serves as an effective and economical mordant in this process. As a leading chemical manufacturer in China, we provide high-quality 17% iron-free Aluminum Sulfate essential for achieving optimal results in textile dyeing operations.

Aluminum Sulfate’s function as a mordant stems from its ability to form coordination complexes with both the dye molecules and the fabric fibers. When used in the dyeing process, the aluminum ions act as bridges, binding the dye to the cellulosic fibers of cotton more securely. This linkage enhances the dye's affinity for the fabric, resulting in improved color depth and significantly better wash fastness and light fastness. The process typically involves impregnating the fabric with a solution of Aluminum Sulfate before or during the dyeing phase.

The 17% iron-free grade of Aluminum Sulfate is often preferred in textile applications to avoid any potential metallic impurities that could interfere with the dye shade or cause unwanted discoloration. Its consistent chemical properties, indicated by CAS No. 10043-01-3, ensure reproducible results batch after batch. For textile professionals looking to buy Aluminum Sulfate, sourcing from a trusted manufacturer in China guarantees product integrity and availability.

Beyond its role as a mordant, Aluminum Sulfate’s general properties as a flocculant are also relevant to the textile industry, particularly in wastewater treatment. Effluents from textile dyeing processes often contain residual dyes and suspended solids, and Aluminum Sulfate can be employed to clarify this wastewater before discharge, contributing to environmental compliance.
