Wrapped Yarns-Three New Options!
Wrapped Yarns-Three New Options! Shieldex and Lederer GmbH are developing three new products. Three types of conductive wrapped yarns are under development. These products are: Wrapped Yarn dyed: Silver plated yarns cannot be dyed. Color can now be added by wrapping the dyed yarn with silver plated yarn. The silver plated yarn is not directly affected by the dyed yarn. This allows the plated yarn to maintain its electrical and thermal conductive properties. Wrapped Yarn Stretched: Using a very stretchable yarn...

Supply Chain Woes- We’ve got the Goods!
Supply Chain Woes-We've got the Goods! The last two years have been crazy for businesses! Shutdowns due to COVID put us all behind production schedule! The suppliers of raw materials were also affected in similarly. Now we are able to work again. Good Employees are hard to come by, slowing production! The current problem is that the supply chain is broken! Many companies have no raw materials or parts to work with. Orders are currently being taken at many companies. ...

Global Reach and Innovation-two Great Assets!
Global Reach and Innovation-two Great Assets! During these tough economic times, we have been very fortunate. The supply chain has broken and is difficult to repair. VTT and our European partner, Shieldex, have excellent global reach. Our two locations, Germany and the USA, make shipping easier. Both of our locations have large standing inventories in stock. We manufacture many of the products that we sell. We have been fortunate to find suppliers of raw goods. This has helped us to...

Non-woven Metalized Fabrics-what are their uses?
Non-woven Metalized Fabrics-what are their uses? The concept of a non-woven metalized fabric is hard to grasp. They are not made by weaving or knitting. They consist of Nylon 6.6 fibers. These fibers are NOT converted to yarns. The fibers are pin bonded together in a three-dimensional matrix. This process yields a uniform fabric with dimensional stability, and high tear and tensile strength. The fabric can be plated with Silver, Copper, Nickel, and Tin. These varied metal platings yield different...

Use a Tenter Frame-Erase Yarn Memories!
Use a Tenter Frame-Erase Yarn Memories! Yarns develop bad "memories" from the knitting process. Think of the knitting process as a traumatic event for the yarn. These "memories" first show up when oils and binders are removed by washing after knitting. The removal of these oils and binders is an "aqueous process". As the yarns dry from the washing, the yarn appears wrinkled. These "wrinkles" are physical swelling or "bellies" caused by the yarn's "knitting memory". These "physical memories" make...

Tough Conductive Textiles-Great in Extreme Conditions!
Tough Conductive Textiles-Great in Extreme Conditions! Much of the work done by conductive textiles is done under mild environmental conditions. They are often used indoors in EMC testing labs, hospitals, and vehicles. They are not able to withstand harsh weather elements. These conductive textiles are thin and fragile. They are vulnerable in their native state. There has long been a need for them in tougher conditions. The textiles just weren't durable enough for it. Architectural Shielding, marine conditions, military operations...

Electronic Data Protection-Buy or DYI!
Electronic Data Protection-Buy or DYI! I've talked about Faraday pouches that protect digital data hacks before. They are security pouches used by government, police, and big business. These pouches prevent data tampering or theft by wireless access. Phones, laptops, and PDAs are protected from wireless access while inside the pouch. These pouches work using the "Faraday Cage Effect" created by metalized textiles. The metalized textiles block passage of electromagnetic fields through pouch walls. This same technology is now available to...

Efficient Best Practice- Frequent EMC Developmental Testing!
Efficient Best Practice-Frequent EMC Developmental Testing! Frequent EMC developmental testing sounds like a lot of work. It also sounds like a waste of precious time. The truth is doing the testing early and often saves a lot of time! "Backtracking" to mitigate/diagnose problems is the real waste of time. Backtracking means "to retrace one's steps" or to "pursue, trace, and monitor". I call it "going back to the drawing board"! Talk about time consuming, that's the definition of backtracking! Pre-Compliance...
