How much does Kevlar® (Aramid) cost?

Aramid fiber is best known by the trademark name DuPont™ Kevlar® and offers many unique and beneficial properties.  With aramid raw material costs between five and thirty times the cost of nylon or polyester, many manufacturers look for ways to save when aramids are required for their application. What seems on the surface like an easy question is a lot more complicated than you might think.  So, what are some of the factors that contribute to the total cost of industrial aramid yarn or thread?

3 Common Industrial Yarn Joining Methods Explained

The practice of joining industrial yarn ends (resulting from breaks, defects, or end of the supply), is a critical component to the product manufacturing process, particularly in industries such as wire and cable (integration of ripcords), hose reinforcement, belting and more. When using industrial yarn in the production process, it is essential that the joining method endures the process without interruption and does not have a negative effect on the quality of the end product.

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.

What is Vectran™?

Vectran™ is a manufactured fiber used to make specialty fabric and typically only those with a specific product application know much about it. This multifilament yarn is spun from a liquid crystal polymer (LCP) and is the only commercially available melt-spun LCP fiber in the world. Vectran™ fiber presents exceptional strength and rigidity because the material is five times stronger than steel and ten times stronger than aluminum. There are no real alternatives when it comes to working with Vectran™ as the qualities it brings to the table are distinctive and highly beneficial.

Polyester Yarn Price Update Part Two: Understanding Market, Spot and Indexed Pricing

In part one of Service Thread’s blog series on polyester yarn pricing, I discussed the reason for the unpredictable cost swings with polyester yarn pricing. In addition to understanding the global dynamics that effect these swings, it is also important to understand the pricing strategies used.

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.

5 Reasons to Use Industrial Yarn as Reinforcement in Beverage Hoses

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.

Guest Post: Effects of Twist on Cord Properties

Spending years in materials science in the tire and rubber industry, I have found large volumes of publications available on most performance aspect of cord properties (strength, elasticity, fatigue, adhesion), and when I run across something on twist I usually make a note of it. I have seen less published data and information available on the effect of twist level on textile cord properties. I have collected a few “rules of thumb” from Takeyama and Fujimoto. Recently at Hailide America Inc, we have looked at the twist effects in an industrial-grade high-tenacity polyester and have found the old tire-cord-twist rules of thumb that apply are actually inverted in the low twist region.

Industrial Yarn Diameter, Gauge - Why is it important?

If you manufacture hoses, cables, or sewn products, yarn diameter or gauge is an important factor in determining what industrial yarn or thread type and construction to use.  Not to be confused with the linear density or size of the material, yarn gauge is the measured thickness of a cross section of material.

Conductive and Non Conductive Yarns

Control of static and current electricity is a crucial consideration in industrial product design. By using combinations of different polymers and coatings, industrial yarn and threads can be designed to help conduct or impede electrical charges as required for different product applications.
