FABRIC SELECTION In selecting a woven fabric for industrial applications, a number of design parameters may be considered. These are broken down into four basic variables: yarn weight, thread count, weave pattern and fabric finish. The wide range of yarn weights provides the base for fabric design. Yarn weight, combined with thread count [the number of warp ends (lengthwise) and filling picks (widthwise) per inch] determines the strength, weight and thickness of Basic weaving concepts are utilized in the manufacture of fiber glass and high performance fabrics. The technology, however, is...

The basket weave is similar to the plain weave except that two or more warp yarns and two or more filling yarns over and under each other. The basket weave is more pliable, flatter and stronger than the plain weave, but is The leno weave is used where relatively low numbers leno weave locks the yarns more warp threads over each other and interlacing with one K or more filling threads. — Four Harness Satin (Crowfoot) The four harness satin weave is more pliable than the plain weave and is easier to conform to curved surfaces typical in reinforced plastics. In this weave pattern there where a...

Eight Harness Satin The eight harness satin is similar to the four harness satin except that one lling yarn oats over seven warp yarns and under one. This is a very pliable weave and is used for forming over curved surfaces. Twill Weave The twill weave is more pliable than the plain weave and has better drapability while maintaining more fabric stability than a four or eight harness satin weave. The weave pattern is characterized by a diagonal rib created by one warp yarn floating over at least two lling yarns 7

CONVERTING YARN TO FABRIC The first step in the warping stage is beaming, where purchased yarn is transferred from the bobbin creel to section beams. Most input yarn is in singles form; however, some yarn is twisted and plied together to yield unique properties. The section beams constitute the machine direction or thread sheet segment of yarn in the loom. Several section beams are produced and consolidated into a group called a set, which provides the input for the slashing process. The slashing process combines the warp ends of the set's multiple section beams into a single beam for...

After the warp beam is installed in the loom, then either rapier technology for heavy fabrics, or air jet technology for lighter fabrics is used to interlace the filling yarns at 90 degree angles to the warp ends on the loom. The fabric, called greige or loom state, is then wound onto a roll or steel drums called mandrels, and the weaving process The next stage is batch oven cleaning, where the mandrels are placed on racks, loaded into large ovens, and exposed to high temperatures until all organic binders are removed and a pure clean glass fabric is produced. Organic, polymer-based fabrics...

CARBON FABRICS NOMENCLATURE 14 Carbon fabrics from Hexcel have a specific nomenclature which enables us to know the fiber used and the weave style as well as any tracers, tracer fiber and the tracer spacing if in the fabric. This nomenclature is referred to as the “description” on our fabric label that is placed on each box of carbon fabric. Here are some examples of the nomenclature for the US and Europe: US EXAMPLES: SGP203CSDL means: S = IM7 Type Fabric GP = GP sizing 203 = 203 gsm fabric CS = Crowfoot Satin (4 Harness Satin Weave) D = SCG 75 1/0 0.7z 933 L = Tracer yarn every 12” in...
