Fabric weave

Ca.rca.ss Construction. Carcasses are made of one or more pHes of a woven fabric bonded together with an elastomeric compound. Woven materials that are used include cotton, rayon, nylon, polyester, aramids, and glass, in the pure form or in blends. The fabrics are constmcted with warp yams that mn lengthwise along the belt, and filling (weft) yams that mn crosswise. There are a variety of fabric weaves available for specific appHcations... 

Fabric weave. Fabric weave pattern can influence the properties such as drape-ability, tightness, etc. of a fiber product. The quantities of relevance in this regard are pick count, fabric areal weight, etc. 

Use High-grade paper (Europe), fabrics (weaving apparel and car seat covers), stem-tube packing in ships, patching water mains (Great Britain). 

With at least two more strips of fabric, weave through the center part of your twig group. Start with the first strip on the right side and the second strip on the left side of the twigs. 

Fabrics woven from Kevlar 49 aramid fiber are often used as composite reinforcement, since fabrics offer biaxial strength and stiffness in a single ply. The mechanical properties of Kevlar 49 aramid are dependent on the fabric constmction. The composite properties are functions of the fabric weave and the fiber volume fraction (typically 50%-55% with ply thickness 5-10 mils, depending on fabric constmction). In 1987, Du Pont introduced high-modulus Kevlar 149. Compared to Kevlar 49 it has higher performance (47% modulus increase) and lower dielectric properties (65% decrease in moisture regain).

High-retraction polypropylene fiber has low thermal conductivity for thermal insulation. It also provides fluffiness with high retraction. This fiber is widely used in blanket, cotton products, synthetic leather, nonwoven fabrics, weaving, and needle knitting. 

Lead oxide has been widely used in the glazing of pottery in flint -type glasses and in solder glasses, but these materials contain no carbon and have no visible structure In the process being reported, carbon contained in the cotton is required for formation of the new chemical structure and for retention of the fabric weave pattern and shape in the new products ... 

Glassy polymers from fabrics with more than 15% lead separate from the 8ubstrate usually as brittle flakes. When these brittle flakes are removed an etched replica of the fabric shape and weave pattern remains on the substrate. This etched substrate surface shows no lead when examined by ESCA. Thus there is only diffusion of silica from the substrate to the lead carbon cellulosic matrix without reciprocal diffusion of lead into the original silica sub-strate The higher the lead content of the fabric the smoother is the surface of the new glassy material. However the fabric weave pattern is still visible in all glassy products. 

In order to test the influence of the fabric construction parameters on valve behavior, different types of woven fabrics were then compared (Heim et al, 2005). The following parameters were varied (1) fabric weave construction (plain weave or satin), (2) fabric tightness, and (3) yarn specific surface area. The fabric tightness was calculated using the Russel construction factor (C) and is described in warp and weft directions by... 

Four-harness satin refers to a fabric weave also named crowfoot satin because the weaving pattern when laid out on cloth design paper resembles the imprint of a crow s foot. In this type of weave there is a three by one interlacing, that is, a filing thread floats over the three warp threads and then under one. This type of fabric looks different on one side than on the other. Fabrics with this weave are more pliable than either the plain or basket weave and, consequently, are easier to form around curves.

Application of weave design as described earlier enables the manufacture of closed woven surfaces even if spacings are increased significantly at some areas of the fabric. As a variation of option (b), additional threads can be woven into the structure only for a limited length. From the position where these threads leave the fabric weave...

Before the 1970s, many different materials had been used as body armour material such as cotton, silk and nylon. Only in the last 30 years, have high-performance materials such as Kevlar and Dyneema been introduced in the body armour industry. Apart from fibre am properties, fabric construction parameters, including fabric weave, yam counts, density and fabric width have also had a significant effect on ballistic performance of body armour. On top of this, fabric (yam) surface treatments are additional parameters that can be considered for the optimum conditions for ballistic application. 

Fabric weave stractures are the types of forms in which the yams are constmcted to produce various aesthetic designs through weaving. The material selection, design and constmction method all play very important roles to ensure the product meets the required geometry as well as the physical mechanical properties.
