The video above features untreated continuous multifilament polyester thread on the left, which burns vigorously once ignition temperature is reached, melts, emits black smoke and drips. Untreated aramid yarn on the right burns with difficulty because of high LOI. The flame extinguishes when the heat source is removed.  Aramid does not melt but decomposes showing signs of thermal degradation.

The video above features NeC 8/4 staple spun polyester. The untreated thread on the left burns vigorously once ignition temperature is reached, melts, emits black smoke and drips. The treated thread on the right melts and drips, however, resists combustion and flaming, therefore, smoke is greatly reduced, retardant has done its job.

Ohm values vary for different industrial yarn and threads. Your choice depends on your specific application - do you need conductivity or static dissipation in your process or product? 

Industrial yarns and threads are made of various fiber types and sizes which aresupplied on a wide range of package sizes with different lengths and yields.  Most products are ordered by the pound, which may leave you wondering, “How long is it?” It’s important to understand the length and yield of your products to help improve your processing efficiency and waste reduction. 

Unlike the September 2018 10 percent tariff, the additional 15 percent announced for shipments on or after May 10th may not have an immediate impact on the price of polyester yarn imports to the U.S.

Trade tensions between the E.U. and the U.S. have continued to escalate after a preliminary list of $11 billion in tariffs was announced in April 2019. In response to European subsidies to Airbus and a subsequent World Trade Organization (WTO) ruling, U.S. textile importers have faced a duty of up to 100% on certain materials.

If you’ve come across the term Cotton Count and were a bit confused, you’re not alone. The terminology of the yarn and thread industry can be tricky.

Tough and durable, UHMWPE (ultra-high-molecular-weight polyethylene) yarns have the highest tensile strength of any thermoplastic. You may also know these yarns by the names Spectra® and Dyneema®.
