转载(olio) Woven fabrics &Knitted fabrics [资料] The textiles are made by various means, such as hand-woven, printing method and mass factory producing and the fibers used also vary according to the preference, cotton, silk, rayon, nylon or polyester. The traditionally hand-woven garment is usually made of cotton fibers, which vary from the size. It also uses normally natural color while printed and mass produced garment use the chemical textile color. The different method of making, treatment and sort of material determine the prices of the garment. Therefore, for the same pattern of garment you choose you can get different prices. Woven fabrics are made of two sets of yarns - a lengthwise set called the warp and a crose set called the filling or weft. The warp yarns are threaded into a loom through a series of frames called harnesses. During the cloth-making process, the harnesses raise some warp yarns and lower others. This action creates a space, or shed, between the yarns. A device called a shuttle carries the filling through the shed and so forms the crose yarns of the fabric. The pattern in which the harnesses are raised and lowered for each pass of the shuttle determines the kind of weave. Knitted fabrics are made from a single yarn or a set of yarns. In making cloth, a knitting machine forms loops in the yarn and links them to one another by means of needles. The finished fabric consists of crose rows of loops, called courses, and lengthwise rows of loops, called wales. This looped structure makes knitted fabrics more elastic than woven cloth. Garment manufacturers use knitted fabrics in producing comfortable, lightweight clothing that resists wrinkling. Other fabrics include tufted fabrics, nets and laces, braids, and felt. None of these fabrics is woven or knitted. However, the textile industry produces another class of fabrics specifically called non-woven fabrics.
