The sizing machine improved the process by sizing a warp before putting it into the loom. The warp threads are first wound onto a large beam, which is then placed at one end of the sizing machine. Then the warp is drawn off the beam and passes through a bath of boiling size, between sets of rollers and cooled, dried and rewound onto another beam.
Desizing, irrespective of what the desizing agent is, involves impregnation of the fabric with the desizing agent, allowing the desizing agent to degrade or solubilise the size material, and finally to wash out the degradation products. The major desizing processes are: Enzymatic desizing of starches on cotton fabrics; Oxidative desizing; Acid ...
Sizing the warp. Textile warp sizing, also known as tape sizing, of warp yarn is essential to reduce breakage of the yarn and thus production stops on the weaving machine. On the weaving machine, the warp yarns are subjected to several types of actions i.e. cyclic strain, flexing, abrasion at various loom parts, and inter yarn friction.
A heald is a loom component also called heddle or harness, used to separate warp yarns for passage of the weft. Commonly made of cord or wire. Minimum two healds are required to weave a fabric with warp and weft in a loom. heddle A heddle is a common loom component, used to separate warp yarns for passage of the weft. Commonly made of cord or wire.
Balanced plain weaves are fabrics in which the warp and weft are made of threads of the same weight (size) and the same number of ends per inch as picks per inch. [3] Basketweave is a variation of plain weave in which two or more threads are bundled and then woven as one in the warp or weft, or both.
Textile fibers, threads, yarns and fabrics are measured in a multiplicity of units.. A fiber, a single filament of natural material, such as cotton, linen or wool, or artificial material such as nylon, polyester, metal or mineral fiber, or human-made cellulosic fibre like viscose, Modal, Lyocell or other rayon fiber is measured in terms of linear mass density, the weight of a given length of ...

Tissue is a thin, transparent, and lightweight material. [1] [2] Tissue fabric is a suitable material for designing various types of garments, including saris. [3] Tissue is characterized by the use of metallic yarns for decorative purposes. [4] The tissue sari is composed of silk threads in the warp and zari in the weft. [5] [6]
