Synthetic yarns like nylon and polyester are typically known for their high shrinkage rate. In order to permanently set the physical properties of these materials after extrusion, they are stretched or drawn at elevated temperatures under tension during the manufacturing process, also known as heat setting. When stretched under these elevated temperatures, changes in physical properties happen and the crystallinity of these synthetic yarns is modified. The general physical properties of the thread or yarn can be adjusted by selecting the specific conditions under which the yarn is drawn, bringing the desired property changes to the material. Heat setting also stabilizes the yarn for future exposure to heat.Read more
Over the past 20 years, more than 100 major sports facilities have opened in the United States to join the thousands already in operation. Throughout these sports complexes, concession stands see a great amount of traffic as fans enjoy stadium food and beverages during events. In particular, beverage hoses are a critical element in the sanitary dispensing of soda, beer and more.Read more
The critical reason for using waterblocking fiber in wire and cable manufacturing is to prevent access and dissipation of water and moisture throughout the cable. In fact, water is the most likely cause of premature failure for cable and electrical equipment. There are two common ways water and moisture finds its way into a cable:Read more
Manufacturers of wire and cable understand the importance of preventing moisture from making contact with fiber optics. Conducting a water wicking test for yarn and thread used in the manufacturing process can help with product evaluation, as well as save time and money in the long term.Read more
PTFE (polytetrafluoroethylene) is a thermoplastic polymer with a very low coefficient of friction along with excellent chemical, temperature, and environmental resistant properties. Commonly known by its brand names of Teflon™ , Yeumiflon® , or Profilen® , PTFE can be manufactured as a specialty fiber or thread for a broad range of applications including filtration, outdoor fabrics, electrical cables, and protective garments.
PVA, or Polyvinyl Alcohol, is a water-soluble synthetic polymer that lends itself to a variety of adaptions. PVA can be made into threads of fibers, liquids, coatings, beads, lubricants, and many other forms. As a filament yarn, PVA has valuable properties:Read more
As a primary supplier to both the thermoplastic hose and wire and cable manufacturing industries, Service Thread has worked with many companies using reinforcement yarns and protective textile threads with their braiding equipment. From what we see in the industry, we’ve created this quick reference list of some of the best yarn braiding machinery manufacturers:Read more
