Chemical Quantity
Synthetic compounds applied to cellulosic fabrics provide the durable press properties required for wrinkle resistant garments. The crosslinking resin mass is measured to ensure that enough finish has bonded with the fiber molecules to hold the fabric shape. This measurement typically occurs after the padding and curing stages of textile finishing.
High concentrations improve crease recovery but can reduce the tensile strength of the cotton fibers.
Application Ratio
Fabric immersion in a chemical bath deposits a specific weight of resin onto the surface. Monitoring the crosslinking resin mass involves weighing the fabric before and after the application of the liquid finish. Adjusting the nip pressure on the padder rollers controls the wet pick up.
This step determines the final performance of the garment.
Performance Impact
Fiber stability improves when the resin creates bridges between the molecular chains of the cellulose. If the crosslinking resin mass is too low, the fabric will wrinkle easily after laundering. If the mass is too high, the material becomes brittle and prone to tearing.
Balancing these two outcomes is the goal of the finish.
Finish Retention
Laundering durability depends on the temperature and duration of the curing oven. A stable crosslinking resin mass remains fixed to the fibers through many wash cycles. Testing for free formaldehyde is often required to ensure the chemical reaction was completed safely.
Final checks confirm the handle and appearance of the cloth.
