Importance of Having Accurate Industrial Yarn Specifications

Example Yarn Specification SheetIndustrial yarn is designed and engineered to be incorporated into products where oftentimes, a functional requirement supersedes aesthetic considerations. Used by non-apparel industry product manufacturers, industrial yarns are typically a component part of a product to enhance the strength, durability, performance and other high-value properties of the product.

What is Ultra-High Molecular-Weight Polyethylene (UHMWPE)?

Polyethylene is the most commonly used plastic in the world, but how do you know if it’s the right yarn for your application? Consider the attributes of ultra-high-molecular-weight polyethylene (UHMWPE) - a very tough subset of polyethylene that has a strength to weight ratio 8-15 times greater than steel.

Vectran™ Vs. Aramid

Both Vectran™ and Aramid yarns are known for being resilient materials used for specialized products. They each have varying degrees of creep resistance, abrasion resistance, high tensile strength, excellent flex/fold characteristics, long term dimensional stability and exceptional property retention at high temperatures. These yarns are extremely durable and often used to protect people and products.

Water Blocking Test Method for Industrial Yarns - Wire & Cable

When yarn used in a wire and cable application prevents access of water and moisture to the critical elements - it is considered to be waterblocking. This feature is also known as water swellable or water absorbent. There are also various treatments that can be applied to a yarn to enhance its waterblocking characteristics. The most important function is that the yarn absorbs or blocks water in a way that stops water from causing damage to your product.

Bonded Polyester vs. UV Treated Polyester: Comparison Results for Industrial Sewing Threads

Manufacturing products for outdoor applications or those that require the product be exposed to UV light, require special specifications to stand up to various environmental conditions. UV degradation of industrial sewing thread is a physical and chemical change that results from irradiation of the base polymers by ultraviolet light. The UV energy absorbed into the thread leads to degradation of the polymeric chain and loss of strength in the thread. It can also affect thread finishes such as bonding as well as causing fading or spotting of thread dye.

What is ASTM D4974? Hot Air Shrinkage Test for Yarn & Cord Explained

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.
