Finishing Bath For Linen Fabric
The finishing bath for linen fabric typically involves various processes and treatments to enhance its properties and achieve the desired characteristics.
Steps involved finishing bath for linen fabric
- Desizing: Linen fabric is often sized during the weaving process to improve its handle and weaving performance. Desizing involves removing the sizing agents applied during weaving, typically using enzymatic or chemical desizing agents.
- Scouring: Scouring is a process of thoroughly cleaning the linen fabric to remove impurities, such as natural waxes, oils, dirt, and other contaminants. It is usually done using alkaline solutions and surfactants to achieve a clean and uniform fabric surface.
- Bleaching (optional): If a whiter or lighter shade is desired, linen fabric can undergo a bleaching process. Bleaching agents, such as hydrogen peroxide or sodium hypochlorite, are applied to remove natural colorants and achieve a more uniform color.
- Mercerization: Mercerization is a treatment specific to cellulosic fibers like linen. The fabric is treated with concentrated sodium hydroxide (caustic soda) solution, followed by neutralization and washing. Mercerization improves the fabric’s strength, luster, and dye affinity, resulting in a more desirable appearance and improved dye uptake.
- Softening: Linen fabric can be softened to improve its drape, hand feel, and overall comfort. Softening agents, such as cationic surfactants or silicone-based softeners, are often applied during the finishing bath to impart a softer touch to the fabric.
- Stabilization: Linen fabric has a tendency to shrink and wrinkle. To minimize these issues, the fabric can undergo a stabilization treatment where it is exposed to controlled heat and moisture. This process helps to set the fabric dimensions and reduce shrinkage and wrinkling.
- Drying and curing: After the various treatments in the finishing bath, the linen fabric is dried using heat or air drying methods. This is followed by curing or heat-setting, which helps to finalize the effects of the applied treatments and ensure their durability.
