Worsted is a yarn and cloth usually made from wool. The yarn is well twisted and spun of long staple wool (though nowadays also medium and short fibers are used). The wool is combed so that the fibers lie parallel. woven fabric A woven fabric is a cloth formed by weaving. It only stretches in the bias directions (between the warp and weft ...
Adaptive scalable texture compression (ASTC) is a lossy block-based texture compression algorithm developed by Jørn Nystad et al. of ARM Ltd. and AMD. [1]Full details of ASTC were first presented publicly at the High Performance Graphics 2012 conference, in a paper by Olson et al. entitled "Adaptive Scalable Texture Compression".
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 ...
Long wool fibres can be up to 15 in, but anything over 2.5 inches is suitable for combing into worsteds. Fibres less than that form short wool and are described as clothing or carding wool, and are best suited for the jumbled arrangement of woolens. At the mill the wool is scoured in a detergent to remove grease (the yolk) and impurities.
Scotswomen walking (fulling) woollen cloth, singing a waulking song, 1772 (engraving made by Thomas Pennant on one of his tours). Fulling, also known as tucking or walking (Scots: waukin, hence often spelt waulking in Scottish English), is a step in woollen clothmaking which involves the cleansing of woven cloth (particularly wool) to eliminate oils, dirt, and other impurities, and to make it ...
A wool bale is a standard sized and weighted pack of classed wool compressed by the mechanical means of a wool press. This is the regulation required method of packaging for wool, to keep it uncontaminated and readily identifiable. A "bale of wool" is also the standard trading unit for wool on the wholesale national and international markets.
All fabrics pill to some extent, although fibers such as linen and silk pill less than most. [6] The primary drivers of pilling are the physical characteristics of the textile (including both the initial fiber, and the way in which it is processed during manufacturing), the personal habits of the textile's wearer, and the environment in which the textile is used.
The origin of the word is not known for certain. It may be a back-formation either from the obsolete noun stapler meaning wool-stapler, a merchant trading in wool who would sort and class the wool according to quality, or else from the obsolete verb staple, to receive goods such as wool at a staple port.
