Benefits of Compact Ring Spun Yarn in Other Spun Yarns

Fiber, Yarn / / / 2 Comments

BACKGROUND In 1991, textile researchers at Universities in Eastern Europe introduced a change in the traditional manufacture of ring-spun yarn. Condensation of the roving web prior to entering the spinning triangle produced a less hairy and more compact yarn structure. Surface fibers from the condensed roving provided reduced protruding surface hair and a smaller diameter […]

Carbon Fibers – the lightweight and super strong man-made fibers

Manmade Fiber, Resources & General / / / 1 Comment

Carbon fiber is a super strong material that is extremely lightweight. It is five times as strong as steel, two times as stiff, yet weighs about two-thirds less. Carbon fiber is basically very thin strands of carbon (even thinner than human hair). The strands can be twisted together, like yarn and then be woven together, like cloth. To make carbon fiber take on a permanent shape, it can be laid over a mold and coated with a stiff resin or plastic. Carbon fiber can also be defined as a fiber containing at least 92 wt % carbons.

Arrangement and Schemtics of Ring Spinning

Ring-Spinning, Yarn / / / 1 Comment

The traveller speed in a ring frame is the main limitation in achieving higher spindle speed because of the frictional resistance of traveller over the ring flange. The design, metallurgy, surface finish and breaking-in of the rings decide the speed at which a ring frame can be run without excessive end breaks. It is important to understand the schematics of the ring travellers in order to achieve maximum productivity from the ring spinning machines.

Types of Yarn Winding

Types of Yarn Winding

Ring-Spinning, Yarn / / / 2 Comments

There are two types of winding machines: precision winders and drum winders. Precision winders, used primarily for filament yarn, have a traverse driven by a cam that is synchronized with the spindle and produces packages with a diamond-patterned wind. Drum winders are used principally for spun yarns; the package is driven by frictional contact between the surface of the package and the drum.
