Treatments designed for application to cotton, polyester or nylon substrates to provide easy release and resistance to wrinkling can be divided into three basic categories:
In tire production, cotton, rayon or polyester fabrics treated with a fatty acid derivative, soap or resin are generally used for calendared stock. Catagory #1 above is probably the most popular treatment. They are generally lower in cost and longevity of release properties under reuse conditions is almost as great as the other more durable polymeric coatings. Another important performance characteristic in the liner business is that the category #1 and #3 treatments above also contain organic sizing compounds to attain a required stiffness or hand.
Silicone treatments are generally applied to cotton and nylon for a variety of inter-weaving and release properties, mostly for non-tire and mechanical applications.
The treatment process generally involves one or two passes through a dip tank containing the treatment chemicals followed by a step to remove excess liquid in a rolling operation with subsequent stretching or holding to constant width on a tenter frame under heated conditions. Our dryer is capable of handling widths from 20" to 84" and temperatures to 300 degrees F. We have the ability to slit, hot-knife slit or seal, pink or overcast edges and reroll to customer specifications.
NOTE: All treatments may very in add-on percentage which is positively correlated to the type of substrate being treated, cost constraints, type of treatment and performance level desired.
