Textile Term: Tow
In textile manufacturing, 'tow' is a group of synthetic fibers or filaments, like polyester, nylon, or rayon, that are bound together.
Melt spinning is the common method of producing these filaments, which involves melting polymer material, then pushing it through a small opening, collecting it on a spool, and drawing the filaments together to create a bundle or tow.
Tow is frequently utilized in the manufacturing of other textile materials, such as fabrics, yarns, and nonwovens. It is also employed in the production of consumer and industrial goods, including ropes, filters, and insulation.
Tow can offer numerous advantages, including increased strength, durability, and flexibility, as well as better management of moisture and heat resistance.
The tow manufacturing process typically comprises several stages, including polymerization, melt spinning, drawing, and winding. During polymerization, monomers chemically bond to form a polymer chain. The polymer is then melted and pushed through a spinneret, a small plate with multiple tiny holes.
The filaments emerging from the holes are drawn or stretched to align the molecules and enhance their strength and stability. Finally, the filaments are collected on a spool to form a bundle or tow.
In summary, tow plays a critical role in textile manufacturing and other sectors, providing a flexible and high-performance raw material for a wide range of applications.
