Fiber is a hair-like strand of material. It is flexible and can be spun or twisted for weaving, braiding, knotting, crocheting, etc. to make desired products. Fibres can be obtained in natural form from plants and animals as well as in synthetic form. Man-made or synthetic fibres are either made up of chemicals or by processing natural fibres to create new fibre structures/properties.
Certain weaves,based on their construction or use are group into categories, For instance , the plain weave may be considered as a standard construction .One of the largest of these classes is that of twill weaves, which are so called because of the peculiar effect they form on the surface of the fabric. Many of the simpler twills have , like the plain weave , acquired distinctive names by which they are readily recogonised by experienced designers.
Routine finishes are applied to almost all fabrics with an aim to improve their appearance. A finish is anything that is done to a fabric after weaving or knitting, to changes its appearance, hand and performance. When a finish is applied, say on cotton, it might become more shiny, stronger or resist shrinking on washing. Similarly, other finishes may make the fabric softer or
stiffer; water or stain resistant; coloured or designed.
Regular twills are those that run in regular order; it is, therefore, simply necessary to know the interlacing of any one end or pick, say the first, of a regular twill in order to show the entire weave on design paper. The interlacings of the first end or pick of any regular twill are conveniently shown by writing numbers above and below a horizontal line; thus, for example,if the first end is up 2 picks, down 3, up 1, and down 2.
