General term for processes after winding concerned in preparing weaver's and knitter's warps. Methods of warping vary according to (1) the yarns employed (2) whether they are sized or not, and (3) at what state sizing takes place. There are at least seven methods of warp preparation, e.g., beam warping, direct warping, mill warping on vertical mills, section warping on horizontal mills and in cheeses on section blocks, Scotch dresser sizing, Scotch warp dressing, and Yorkshire warp dressing. Beam Warping is the system in general use for making grey cotton goods. The beam warper comprises a creel for the supply ends, which may be on double-flanged bobbins, cones or cheeses, and a beaming head which comprises mechanism for mounting and rotating a warper's beam and means for winding the yarn from the creel supply on to the beam under suitable tension. The number of ends and length of warp on a back or warper's beam is related to what is required in the weaver's beam. Assuming the weaver's beams were required to have 2928 ends, 24's warp, and 8 cuts of 96 yards each, the back beams for a set might have 2928: 6 = 488 ends, and 2 X 6 X 8 X 96 = 9216 yards. On the slasher sizing machine six back beams would be run together, thereby producing 12 weaver's beams each containing 2928 ends 768 yards long. Warp Beaming Speeds - With the old type of warp beaming machine taking supply from unrolling double-flanged bobbins, the warping speed would be about 70 yards per minute. In modern beam warpers taking supply overend from cones, the warping speed is up to 250 yards per minute. With beam barrels of 4¹/₂-in. dia., and up to 500 yards per minute with barrels of 10-in. dia. Warp and Weft Knitted Fabrics - Warp knitted fabrics in which extra yarn is introduced in the form of weft threads which are laid in between the warp threads and their needles for the purpose of adding extra weight and for patterning purposes. Warp Loom Tapes - Narrow knitted fabrics usually less than one inch wide used for trimming garments. They are knitted on circular latch needle machines, but the tapes are flat. Direct Warping - A method used in making warps for towels, fustians, and other fabrics in which the total number of ends can be accommodated in one creel, say not more than 1,000 ends. The threads are run from the creel direct to the weaver's beam on a machine similar to that used in section beam warping. Mill Warping - There are two distinctly different methods of mill warping. On the vertical mill, which may be anything up to 20 yards in circumference, the number of ends in the complete warp is obtained by repeating the runs the required number of times, e.g., with 200 bobbins in the creel, 4 runs would give a warp of 800 ends. The length of the warp is determined by the number of revolutions made by the mill for each run. The horizontal mill is much used in Yorkshire for making woollen and worsted warps It is used to a small extent for cotton warps and is largely used for making silk and rayon warps. The mill or swift is usually about 5 yards in circumference. Its distinctive feature is the making of warps in sections which are wound on the mill in overlapping manner. The creel capacity varies from 250 to 600 ends, and with 500 ends in the creel a warp of 5,000 ends would require ten sections. Section Warping for Coloured Goods - This is a system of making coloured striped warps from hank-dyed and bleached yarns. The bobbins are creeled to pattern, one or more complete patterns to each section. Each section is the full length of the warp and is run on a small section block keywayed to fit a key on the shaft of the subsequent beaming machine where the sections are placed side by side and run on the weaver's beam. Scotch Dresser Sizing - There are two systems of warp preparation known as Scotch dressing. 1. Dresser sizing used for sizing warps for linen damasks, etc. Back beams are first made and placed in two beam creels, one on each side of the headstock. The threads from several back beams are collected in one sheet of yarn, sized by passage through a size-box, brushed by a revolving brush, dried by hot air, and passed vertically upwards where both sheets of warp threads are united and pass on to the weaver's beam in a single sheet. Scotch Warp Dressing - The other method of Scotch dressing is used in the preparation of coloured striped warps, usually from warp-dyed and bleached yarn. It consists in splitting off from ball warps previously dyed or bleached and sized, the number of ends of each colour required in the finished warp. Each group is then wound on separate flanged warpers' beams. These beams are placed in a creel and the ends drawn through a reed according to pattern, and wound finally on to the weavers' beams. Yorkshire Warp Dressing - This is a system used mostly in the preparation of coloured striped warps. It is also invaluable in preparing warps dyed and sized in warp form to prevent shadiness in the cloth. Four warps with the same number of ends in each are dyed the same colour, and in sleying, one end from each warp is put in each dent of the reed. Any tendency to shadiness arising from irregularity in dyeing is thereby effectively eliminated. In striped work the required ends are split off if necessary from a larger ball warp, sleyed to pattern in the reed, and then run under controlled tension on to the weaver's beam. The dresser uses a brush as long as the width of the warp to brush out entangled places where the threads have adhered together with size. Yorkshire dressing provides perfect warps with every thread in its proper place on the weaver's beam, no crossed or missing threads, and a minimum of knots.

The true repp is a plain weave fabric having both warp and weft arranged one thread fine, one thread coarse. The coarse ends are always lifted above the coarse picks, and fine ends over the fine picks, thus producing more prominent transverse ribs than those of the poplin. Two beans are used, with the fine warp more heavily weighted than the coarse warp. The illustration shows the true repp weave in cross-section, A is the coarse warp and C coarse weft, B is fine warp and D fine weft. A and B are alternately set.

Silk yarns are composed of a number of silk filaments twisted together, usually 8 to 12 to form a thread. The filaments have a natural coating of gum which gives strength and elasticity, but reduces lustre. The gum must be boiled off if lustre is wanted, which may be done either in the yarn state or when woven in cloth. Silk yarns are divided into two classes, " thrown silk" and " spun silk," the first being yarns that are made by the processes of reeling and throwing, and the second consisting of yarns spun from waste silk. Thrown Silk, or Net Silk comprises organzine and tram yarns, organzine being made from the most perfect cocoons and used for warps. Tram is made from the inferior cocoons and used as weft. All silk contains a proportion of natural gum, and the amount of gum removed give rise to the following terms: - Boiled-off Silk - Yarn which has had all the gum removed, and has the highest sheen (see Boiled-off). Hard Silk - Yarn that has not undergone any boiling-off process. Ecru Silk - Yarn boiled to remove about 3 per cent to 5 per cent of the gum by light washing in lukewarm water. Souple Silk - Yarn boiled to remove about one-sixth of the gum. Bengal Silk - See Bengal Silk. Berlin Silk - A silk yarn made for fancy hand work. It is produced by doubling from 4 to 8 twisted singles grege by a right-hand twist; then again doubling three of these with a left-hand twist. The thread is very round, smooth, and hard, also known as cordon-net. Blond Silk - A special silk yarn made by doubling three grege threads left-hand twist, then doubling three of these together with right-hand twist. Brights - Silk which has been entirely de-gummed in the skein and then dyed. Bourette, Bourrette Yarn - A low grade of silk yarn made from the waste produced by schappe spinning. Canton Silk - See Canton Silk. Chiffon Twist - Single raw silk threads, 50 or more turns per inch. Used for chiffons, crepe-de-chines, etc. Crepe-de-Chine - Hard twist tram silk, about 40 to 70 turns per inch. Made from 3 to 5 raw silk ends. Usually woven as weft. Crepe Georgette - Hard twist raw silk usually made from two threads 13/15 deniers, 50 or more turns, both right and left twist, used for crepe georgettes as warp and weft. Crepe Twist - This is tram silk hard twisted, having from 30 to 100 turns per inch. Used for making fabrics of a crepe character both all silk and mixtures. Cordonnet Silk - See Berlin Silk; also under Cordonnet. Eri Silk - A raw silk obtained from the wild silkworm " Attacus ricini." Flock Silk - A general term used to indicate silk yarns made from the outer uneven parts of the cocoon. Floss Silk - Used principally for embroidery purposes. It is a thrown silk and made by doubling two thick raw singles with right-hand twist together with a left-hand twist. Galette Silk - A coarse silk yarn made from waste. Grenadine Silk - Organzine silk with a large number of turns per inch. Jaspe Silk - Silk warps printed in the hank. Ombre Silk - Skein dyed yarn in a gradation of shades, which run in sequence of depth of colour, varying from five up to forty shades. Schappe Silk - A spun silk yarn which is made from silk degummed by the maceration process used on the Continent (see Schappe Silk). Soie Ondee - See Soie Ondee.

A fancy dress cloth made from spiral yarn warp and mixture weft (cotton and wool). The design is a small spot on 10 shafts; piece-dyed black or blue. This cloth is set 68-in., 18 ends and 18 picks per inch, warp one thread of 5's twisted to one thread of 20's The single threads are both hard twisted and have only six turns per inch in the doubling. The weft is coarse single yarn spun from about 80 per cent wool and 20 per cent cotton to 6 yards per dram. The cloth is shrunk to 54-in.

Originally a silk cloth with warp predominating over weft. The weft is almost completely covered, giving a very smooth warp face. The best satin weaves are those in which the intersections are distributed widely and equidistantly spaced. Satin weaves can be made on any number of ends and picks above four, but the perfect satins, e.g., those in which the intersections are equidistant in warp and weft are few, see examples numbered 5, 10 and 13. The 8-end satin also has good distribution of the intersections. In all satin weaves each thread and pick intersects once only in each repeat. This permits fabrics to be made with a greater number of warp threads per inch than picks; or a greater number of picks per inch than warp threads. In both cases maximum smoothness of surface appearance is obtained, especially when the Schreiner finish is applied. A great variety of fabrics are made in the satin weave; silk, rayon, wool, cotton, flax, etc., are all used. Silk satins very often have a cotton back formed by using cotton yarn as weft.
