Woven Constructions

Woven reinforcement material constructed is by interlacing fibers, yarns, or filaments to form such fabric patterns as basket, plain, harness, satin, leno weaves, scrim, etc. These different weaving patterns are used to provide different processing and/or directional properties. There are filling threads that represent threads in the so-called machine direction warp threads represent those in the transverse direction or at 90° to the filling threads.

Historical. A detailed visual examination of the textiles, both macroscopic and microscopic, was done to determine motifs, techniques of woven construction, color, and fiber content. Many literary sources were used to identify the fragments, including the Survey of Persian Art by Pope and Ackerman (13), Persian Textiles and Their Techniques by Reath and Sachs (3), plates from the volumes on Persian and Indian textiles by Riefstahl (14), and Bunt (15). In... 

The fabrics used in this study were prepared by the Southern Regional Lab especially for the 13 states involved in the S-163 Project. They Include 100% cotton, 100% polyester, and a 50/50 cotton/polyester blend. Fabrics are print cloth, woven construction, with a thread count of 70W x 78F, 3.5 ounce per square yard. All fabrics were wet finished and heat set. A durable press finish (DMDHEU) was applied to cotton and cotton/polyester fabrics. A water repellent fluorocarbon finish (Corpel) and an acrylic acid soil-release finish were applied to all three types of fabrics. Our preliminary findings for the AATCC spray test are reported here. 

Knitted This woven fabric has an interlacing (interloping) yarn or thread in a series of connecting loops with needles. This is a rather compact woven construction. 

The traditional market for cellulose acetate and triacetate fabrics is women s apparel. The appealing characteristics of silk-like softness that pleases the hand, comfort, attractiveness, and low cost account for the demand in textiles. Acetate yams are evenly divided between tricot-knit and woven constructions. Principal markets for women s apparel are dresses, blouses, lingerie, robes, and housecoats. Other textile markets are decorative household applications such as draperies, bedspreads, and casements. Acetate has replaced rayon as liner in men s suits and in nonapparel applications such as for curtains and caskets [82]. 

Different types of breathable components can be classified into following groups, based on the basic component used in the multilayer constfuction. A suitable substrate is essential to support a membrane and/or coating whereas in some cases, such as closely woven construction, a single fabric can be used in isolation. Examples of these include ... 

Bi-directional woven construction laminates do not perform as well as unidirectional materials. The presence of crimp in the fibres gives rise to a local stress concentration in the polymer which may cause cracking and allows the fibre to straighten out under stress. Non-woven continuous fibre reinforcements are preferred in critical applications. The least resistant constructions to creep are the random discontinuous short fibre reinforcements, as they contain a multitude of fibre end stress concentrations and higher shear stresses developed in the polymer to couple between fibres. 

Three types of manufacturing systems can be used to produce three-dimensional woven constructs ... 

Flat belts are still widely used for power transmission. Their thin, flexible cross section allows them to operate over small diameters and, in some cases, at very high speeds. Many different sizes and constructions are available for a wide variety of uses. Flat belts are made either of fully molded or woven construction and may or may not have a tensile member. 

Drape of woven fabrics induced by gravitational force is influenced by a combination of certain deformation properties and structural characteristics. Stiffness, shear and extension are the relevant measure of deformation, while fabric weight and thickness are the appropriate structural characteristics. The type of woven construction (for example, plain, matt, twill, satin) is also a factor influencing the drape of woven fabric. Many researchers tried to find out the relationship between the fabric drape behaviors with the fabric mechanical properties. A brief of their findings are discussed below.
