The textile industry relies on a spectrum of chemicals to transform raw fibers into finished fabrics with desired properties. Among these, sodium hydroxide (NaOH), commonly known as caustic soda, holds a position of paramount importance. NINGBO INNO PHARMCHEM CO.,LTD. recognizes NaOH as a critical component that significantly enhances fabric quality, particularly in processes like mercerization, dyeing, and finishing.

Mercerization is a key treatment for cotton fabrics that significantly improves their properties. This process involves treating the cotton under tension with a concentrated sodium hydroxide solution. The caustic soda swells the cotton fibers, causing them to become more rounded and crystalline. This structural change results in increased luster, improved strength, and a smoother surface that is more receptive to dyes. The efficacy of mercerization is directly linked to the quality and concentration of the sodium hydroxide used in textile processing.

In dyeing and printing operations, sodium hydroxide plays a crucial role in creating the alkaline environment necessary for many types of dyes to react effectively with textile fibers. For reactive dyes, which are commonly used for cotton and other cellulosic fibers, NaOH is essential for the fixation of the dye to the fiber. It helps to create the optimal pH for the covalent bond formation between the dye molecule and the hydroxyl groups of the cellulose. Without the correct pH, achieved through the careful addition of NaOH, dye uptake and colorfastness would be significantly compromised.

Furthermore, in the finishing stages, sodium hydroxide can be utilized for various purposes, including scouring to remove natural impurities from fibers and as a component in some finishing formulations. Its ability to saponify fats and oils makes it effective in cleaning processes.
