A spinneret is used to produce polymer fibers through an extrusion process. Polymers are turned into liquid and forced through small holes in the head of the spinneret, creating long threads that are cooled and hardened. Synthetic fibers produced in this technique tend to be strong and durable. Cleaning techniques are available for the head of the supply chain, and research and development departments are constantly analyzing the production of fiber chains.
A spinneret is a piece of industrial equipment used in the production of polymer fibers. Using an extrusion process, a plant can force liquid polymers through the spinneret, turning them into long filaments that harden into usable fibers. This process is similar to that seen with spider silk, and the name of this equipment comes from the organ spiders used to produce thread for webs and other activities.
The process of creating fiber with a spinneret begins with the preparation of polymers, either by melting or solvent treatment to turn the polymer into a liquid substance. Dyes can be added to create colorful products, or the finished fiber can be dyed after processing, depending on the type and intended use. As it is forced through small holes in the head of the spinneret, the chains in the polymers align and create long threads. The air or liquid on the other hand provides a cooling bath to harden and temper the fibers so they are usable, and the company can wind them onto spools for distribution.
This process is known as gel or polymer spinning. Manufacturers with this capability can distribute the resulting fiber to textile companies or produce their own fabrics in house, depending on the types of products and services they wish to offer. Synthetic fibers produced in this technique tend to be strong and durable and range from Kevlar® for bulletproof vests to polyester for clothing. Supply chain conditions must be tightly controlled to achieve the best results.
The head of each supply chain represents a point of vulnerability in the system. The tiny holes can become clogged with polymers and impurities and render the device unusable. Cleaning techniques are available, including in-service cleaning and removing the treatment heads to a different facility to remove layers of polymers and other materials that could clog them. Companies that offer cleaning services are available for businesses that don’t want to manage their own maintenance needs.
The research and development departments constantly analyze the production of fiber chains. These departments study new ways to produce synthetic fibers and work on developing new types of fiber to meet consumer needs. Some are also investigating ways to improve the design of spinnerets to address common problems or make it possible to produce unusual fibers. Textile engineers doing this type of research usually have advanced degrees and are very familiar with the physics behind polymers and the formation of polymer fibers.
