What Kind of Ripcords Are Used in Wire and Cable Manufacturing?

Ripcords are industrial yarns located longitudinally just under the jackets that cover conductor wires in cables.

The purpose of a ripcord is to cut back the jacket to expose the wires of the cable so you don't run the risk of cutting any of the wires inside (you pull the cord, it cuts the jacket). This helps make splicing cables easier during installations.

Industrial Sewing Thread Sizes Explained

Choosing the correct thread size for the specific applications is important in the yarn and thread industry, where thread size is the primary consideration for meeting the requirements of the finished product.

ASTM D7016 - Importance of fire retardant sewing thread in mattresses

Many products use components created in places other than the final assembly site. Each component must itself conform to safety standards. The logic here is that if something is composed of parts that each pass safety tests, the final product will be safety compliant. A mattress is such a product, and its materials must be fire resistant so that the product sold to consumers can be deemed safe.

What Are The Differences Between Meta-Aramid And Para-Aramid yarns?

When a manufacturer is seeking a synthetic fiber that addresses heat and flame resistance, or one that demands extreme tensile strength, two materials immediately come to mind, the commercially branded Dupont™ Nomex® and Kevlar® composite materials. Each of these belong to the class of aramid fibers with the general characteristics which include a high melting point, a high strength to weight ratio and low elongation at break. These composite materials were developed by Dupont™ labs in the sixties and although Nomex® and Kevlar® are similar, they belong in different 'aromatic polyamide' classes, that is the meta-aramid and para-aramid fibers, respectively.

The UV Resistance of Polypropylene and Polyester Explained

Plastic fibers have found their place in the modern world by their many applications. Polypropylene and polyester are two families of plastics that are common for people to use day-to-day. For industrial uses, polypropylene and polyester have very different characteristics that make them suitable for different environmental stresses including sunlight exposure. Understanding the differences in UV resistance between polypropylene and polyester can help you decide the best yarn or thread for your application.

Left Twist Vs. Right Twist Industrial Sewing Thread

Choosing the correct twist for the industrial sewing thread used in your application is an important consideration in how smoothly your manufacturing process works. That is why it's important to know the difference between left twist and right twist industrial sewing threads.

Industrial Multifilament Yarns and Importance of Twist

Twist can impact the dynamics of your final product in many ways – strength, elongation, diameter, torque, lustre, softness etc. Unlike staple spun yarns, multifilament yarns lose strength as the twist is increased, therefore it is important to know the physical requirements required in the end product. Elongation increases with increasing twist, as does diameter, torque and lustre. Yarns become stiffer with twist therefore softness decreases.

Improving Karg Braider Performance with Yarn Bobbin Design

 One of our large industrial hose manufacturing customers had problems getting long lengths without yarn breaks or run outs in their Karg reinforcement yarn braiding department.  Like most fluid hose manufacturers, they were using a combination of flanged bobbins wound in-house and cardboard prewound braider tubes to meet their production scheudule demands.
