Spinners to Check Out Automated Materials Handling Systems at ITMA.

Yarn producers from the United States attending ITMA 1995 will be seeking upgraded materials handling systems that offer automation, faster speeds, computerization, training tools, and improved maintenance procedures. Automated materials handling systems generally focus on several key points within an open end operation--transporting cans..

Determining the Cost of Spinning.

The Spinning Calculation Program (SCP) is a dialogue oriented software tool that determines manufacturing costs for four different types of short staple yarns under a variety of manufacturing conditions. The SCP, which comprises several modules linked within a main program, instantly calculates costs for producing carded and combed ring s..

Sutures.

The raw materials utilized for sutures include both natural and manmade fibers. The selection of raw material depends on the preferences of the surgeon, desiring knotting characteristics, concerns about potential infection, supply and price variability, and the type of medical procedure. Multifilaments for sutures must meet United States ..

The Influence of Yarn Quality on Downstream Processing.

High speed machinery and the demand for greater efficiency during downstream processing increases the need for higher quality yarns. High speed weaving makes yarn sizing alone insufficient to ensure higher productivity and increases the need for more elastic yarns. Consumers of knitwear are demanding softer hand, which demands an increase..

Effects of Spread Width on the Structure, Properties, and Production of a Composite Yarn.

Researchers characterized the effects of spread width on the structure, properties, and production capacity of a novel, evenly blended cotton staple fiber/polyester multifilament bicomponent yarn. Tests employed a modified Rieter GO/2 spinning frame with spreading electrodes and condensers. Spread widths in excess of 8 millimeters yielded..

Thread: The Key to Product Quality.

A review of trends in idnustrial sewing thread production considers the properties of twisted multifilament, bonded monocord, interlinked multifilament, entangled multifilament, and single strand threads. Some manufacturers use a bonding agent to hold the threads together and to improve the abrasion resistance of the twisted multifilament..

Sewing Threads from Basalt for Special Use.

Scientists in the Czech Repulbic produced basalt sewing threads. The basalt threads had sufficient strength, a high softening temperature, good chemical resistance, and a high resistance to hydrochloric, nitric, and sulfuric acids. The abrasion resistance of the basalt threads, however, was low. The abrasion resistance could be improved b..
