SPINNING A Yarn is usually of substantial length & of a small cross-section. In the cross-section of yarn, there are usually multiple numbers of Staple fibers (short fibers) or Filaments (long fibers) of unlimited length. Spinning is the process of creating yarn (or thread, rope, cable) from various raw fiber materials. Several fibers are twisted […]
Denim is made from a tightly woven twill in which the weft passes under two or more warp threads. Denim is an indigo-dyed cotton twill fabric in which the weft passes under two or more warp yarns.
Physical properties of warp yarn are improved by incorporating oligomer resin into the yarn interior at the size box. These improvements yield benefits at each step of the fabric formation process from size box to the woven greige fabric. Warp sizing technology has been in a period of stagnation following the introduction of synthetic polymers into size formulations nearly 60 years ago. As noted in the following “Warp Sizing: A Brief History”, abrasion-resistant surface barriers may have reached optimum performance in sizing.
Higher quality yarn improves the weaving process. Introduction of very small non-film forming resin particles in conventional size formulations modify and provide improved fiber cohesion in the warp yarn bundle. This transient effect provides a more compact and improved yarn substrate to host conventional warp size polymers on the yarn surface. Evaluation of this technology in producing mills has provided positive results in all factors associated in the weaving process.
Nanometer (Nm) resins have been shown to modify fiber behavior in existing textile yarn. Incorporation of nanometer (Nm) resins in conventional warp size formulations improve weaving performance, improve fabric quality and reduce cost.
The effect of shed geometry has been studied on a loom under the combination of weaving conditions that give the best cover and least stress on loom and warp yarns determined.
Warp sizing is the process of giving a protective coating on the warp yarn to minimize yarn breakages during weaving operation.
Major weaving patterns such as plain, twill, satin, Dobby, Jacquard, Pique, Pile, its characteristics, usages and techniques.
In weaving, no matter what type of weaving is being done, four major operations are performed in sequence and are continuously repeated, they are Shedding, Picking, Beating Up, Taking Up and Letting Off.
Skip twills are a type of broken twill effects formed by a skip drawing-in draft and a regular twill weave as a chain draft. The weaves that form a wave effects across the cloth known as pointed twills. These effects are also frequently spoken of as herring banes, or herring-bones stripes, because the radiating twill lines suggest the radiating bones of a fish’s backbone.
