A specialized treatment applied to cotton fibers yields a yarn with enhanced luster, strength, and dye uptake. The process involves immersing the cotton in a sodium hydroxide solution under tension, causing the fibers to swell and realign. This alteration in structure results in a smoother surface that reflects light more effectively, imparting a characteristic sheen. An example of its application can be found in premium knitwear and crochet projects where a refined aesthetic is desired.
The importance of this treatment lies in its ability to improve the inherent qualities of cotton. By increasing its tensile strength, the resulting yarn becomes more durable and resistant to wear. Furthermore, the enhanced absorbency allows for richer, more vibrant colors when dyeing. Historically, this process was developed as a means to make cotton resemble silk, adding value and appeal to a widely accessible textile.
