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 ...
By this method it is possible to check an unknown weight of yarn with a regular pencil and ruler [3] without unwinding the yarn. Simply slip the pencil under approximately an inch of the strands and count the number of strands. [3] Wrap the yarn around a large needle or a ruler. Make sure the yarn lies flat.
Yarn is selected for different textiles based on the characteristics of the yarn fibres, such as warmth (wool), light weight (cotton or rayon), durability (nylon is added to sock yarn, for example), or softness (cashmere, alpaca). Yarn is composed of twisted strands of fiber, which are known as plies when grouped together. [19]
The yarn is processed by knitting or weaving, with color and patterns, which turns it into cloth. The machine used for weaving is the loom. For decoration, the process of coloring yarn or the finished material is dyeing. [1] For more information of the various steps, see textile manufacturing
The industrial revolution in the 18th century led to mass production of yarn and cloth, which led to the growth of the woven fabric part of the textile industry. [117] Warp and weft: Knitting: Knitting involves interlacing loops of yarn, which are formed either on a knitting needle, needle, or on a crochet hook, together in a line. The ...
Originally meant also as part marking code, this shorthand notation is widely used in electrical engineering to denote the values of resistors and capacitors in circuit diagrams and in the production of electronic circuits (for example in bills of material and in silk screens).
Cotton fibres differ in terms of staple length and other physical characteristics; this is an inherent feature. [5] Bale management, also known as "bale mixing," is the process of analysing, classifying, and then blending fibres from various bales [which also includes the bales received from other stations] according to their fibre properties ...
A stitch is a single turn or loop of the thread or yarn in sewing, knitting, and embroidery. All stitches made with a sewing needle with an "eye" or hole are variations on seven basic stitches: running stitch , backstitch , overcast stitch , cross stitch , buttonhole or blanket stitch , chain stitch , and knot stitch .
