Dyeing cotton and polyester-cotton blended fabrics presents unique challenges, from managing natural impurities to ensuring consistent dye uptake in varying water conditions. To achieve the desired color depth and fastness, specialized chemicals are indispensable. NINGBO INNO PHARMCHEM CO.,LTD. is proud to offer HA-AL, a multifunctional dispersing chelating agent that serves as an essential specialty chemical for cotton and blended fabric dyeing.


For polyester-cotton blended fabric dyeing, HA-AL plays a critical role in preventing cotton impurities, which might dissolve in acidic mediums, from precipitating in the subsequent alkaline dye bath. This issue is particularly prevalent in jig dyeing processes. By incorporating HA-AL at the initial stage of dyeing, manufacturers can proactively avoid such precipitation, ensuring a cleaner and more uniform dyeing result across both fiber types.


When it comes to cotton fabric dyeing with reduced dyes, HA-AL’s function as a protective colloid in alkaline dye solutions, combined with its significant complexing effect on metal ions like calcium and magnesium, proves invaluable. Its use eliminates the need for separate protective colloids or complexing agents, simplifying the process and reducing material costs. This makes it an attractive option for those looking to buy cost-effective solutions for textile auxiliaries.


Crucially, for cotton fabrics dyed with reactive dyes, conventional EDTA-type complexing agents can sometimes leach metal ions from dyes, compromising color fastness. HA-AL, however, avoids this issue as it does not attack metal complex dyes. It can effectively replace polyphosphates at the same concentration in reactive dyeing processes, ensuring high color fastness and vibrancy. NINGBO INNO PHARMCHEM CO.,LTD. stands as a reliable supplier, offering HA-AL at a competitive price for all your cotton and blended fabric dyeing needs, guaranteeing superior fabric quality with every batch.
