A fancy yarn composed of four threads doubled together. A hard twist two-fold thread is doubled with three other single threads in a reverse direction and with fewer turns per inch. These fancy yarns are also made of three threads doubled together in which case the hard-twist yarn is thicker than the others. Sometimes silk is used as one of the threads to give further character.

The twist is assumed to be balanced in a two-fold yarn when half as many turns per inch have been inserted in the doubling process, as were previously inserted in the opposite direction in each single thread. Theoretically, each turn of reverse twist in the doubling takes a turn out of the single twist, and in twisting together two single threads which contain, say, 20 turns per inch, the twist will be balanced when 10 turns of reverse T. have been made. It is not usual to obtain balanced T. in a two-fold yam, the number of twists in which more nearly approaches the number in the single threads, and, in this condition, very little twist is left in the single threads. (W. Watson.)

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.

(See knitting). All yarns used for knitting are termed hosiery yarns in Leicester, but in America only yarns actually used for knitted footwear come under this term. These yarns are much softer than required for weaving. Miscellaneous Yarns - Goat wools, such as llama and alpaca are employed in spinning. yarns for the knitting trade. Vicuna and camel yarns are used to a limited extent. Ramie yarn is specially employed for knitting gas mantle fabrics. Soft spun flax yams have been used for making underwear fabric. Chenille and other manufactured threads are used to a small extent in warp knitting. Composite yarns, such as union yarns - spun from a mixture of wool and cotton fibres; cordon yarns - cotton and worsted singles, doubled together; wool and rayon or spun silk, cotton and rayon or spun silk are largely used to produce self or two-colour effects. Fancy yarns, such as slub yams, voiles, and curled and loop yarns are also employed. Hosiery Yarns (Cotton) include condenser, hosiery, condenser lisle thread, mercerised and sewing cottons. Condenser yarns are spun in coarse counts from low-grade cotton, Indian and American. They are carded, condensed and mule spun, and possess little twist. Hosiery cotton yarns vary considerably in counts and qualities, practically all varieties of Indian, American and Egyptian being used in varying proportions to obtain suitable mixture for quality and price. Cheaper yarns are carded and mule spun. American and Egyptian cotton yarns are combed mainly with the object of removing seed particles. High-class Egyptian and Sea Islands cotton yarns are super-combed. The chief features of a hosiery cotton yam should be: (1) Regularity; (2) cleanliness; (3) fullness. Regularity prevents the making of cloudy fabric, showing thick and thin places. Cleanliness is essential, as the seed particles clog the eyelet hole in the yam guides and cause breakages. Fullness is desirable to cover the loop interstices. Elasticity and pliability are quite as essential as tensile strength. Yams are usually soft spun and if two-fold soft doubled, average twists in two-fold being 2/10's 6¹/₂T., 2/20's 8¹/₂T., 2/30's 10T., 2/40's 16T., 2/80's 20T. Softer twist less 25 to 30 per cent of average (T= turns per inch). Lisle thread is a comparatively hard-twisted and doubly-gassed thread in which there are no projecting fibres. It is always of a two-fold character, and the doubling twist varies from 24 to 34 turns per inch in 2/60's. It is used largely in the manufacture of ladies' hose tops and feet and for lace hosiery. Mercerised yams are used largely in the fancy trade, a comparatively soft twist again being employed. Sewing cottons for seaming, linking and making-up are specially prepared in two to six cord open and reverse twist. Woollen and Worsted Yarns include lamb's wool, wheeling, skein yarns, gala yams (woollens), worsted, crossbreds, fingering, cashmere, dry spun botany (see under each name). Worsted and crossbred yarns of various qualities are used. These yams are spun softly with " hosiery twist." The drawing may be open, cone or French, and the spinning may take place on cap, ring or flyer frames. The chief essentials of hosiery yarn are softness of fibre, fullness, minimum of twist consistent with the requisite tensile strength, regularity, pliability and elasticity. Cashmere Yarns, as used in the knitted goods industry, are spun from short, loose and weak wools as well as from better qualities by French drawing and mule spinning. A small proportion of real cashmere is used for outer garments. In recent years nylon yarns have been largely employed.

The waste used in the spinning of cotton condenser yarns is chiefly the best class of hard waste, viz., cop bottoms, with sometimes a judicious addition of reelers' and winders' waste. The selection of material to be used in the production of condenser yams requires very careful attention and no small amount of skill and experience. Apart from colour, the guiding feature in the mixing of cop bottoms is uniformity of counts of the waste threads within certain limits. When one considers the factors employed in determining the standard amount of twist per inch in cotton yarns, viz., counts X 3.25 for weft, and counts X 3.75 for twist, it is obvious that if, say, 24's American and 80's Egyptian were mixed together the treatment necessary to tear the threads of 24's back again into fibre would not be nearly sufficient to put the 80's into the same condition. The result would be badly broken-up material, which would hamper the subsequent operations to an alarming extent. Assuming, then, that the waste purchased is of suitable quality, the first operation is to put down a mixing of the selected grades. The most satisfactory method is to spread layer after layer until the mixing is of sufficient size or weight. The attendant should then pull the waste along the whole of the face of the mixing. In this way a thorough blending takes place, with the risk of variation in shade reduced to a minimum.

The French term for raw silk yarns run together without twist. It is reeled from cocoons and used either as it is or when converted into tram or organzine by throwing. ———————— A term applied to the filaments produced by silkworms in the form of cocoons. The term also applies to the threads produced by reeling the filaments from a number of cocoons together. Each filament (bave) consists of two fibres (brins) joined together by gum and the length varies from about 500 to over 1,200 yards. Various counts ranging from 8/10 denier to 20/22 denier are reeled, 13/15 denier is the most usual and this is produced by reeling from five cocoons. It has no twist. There are nine different qualities of Bombyx Mori silk in commerce, whether from Japan, China, Italy or India. They are: - Bons Cocoons, Cocoons Pointus, Cocoons Foibles, Cocoons Doubles, Cocoons Satines Goufflons. Cocoons Ouverts. Cocoons Chiques, Cocoons Taches, Dragles.

Thick strong twist, made by twisting together two or three untwisted raw silk threads to the left, and then combining two or three of the composite threads with a right-hand twist. The yarn has a soft handle.

The twisting together of two or more threads to make a stronger or fancier thread. The operation consists in drawing threads from two or more cops or bobbins and twisting them together with the required number of turns per inch. This amount of twist varies considerably according to the purpose for which the yarn is required. Fewer turns are given to yarns for mercerising and hosiery, but yarns for sewing cotton or making healds require a great amount, 2/100's for instance, varies from 15 to 40 turns per inch. Many crepe yarns have 60 or more turns per inch. Doubled yarns possess greater strength and elasticity than a single yarn of the same weight (see Cop and Cop Doubled Yarns)

A mule machine used for doubling and twisting two or more threads together at one operation. It has similar general features to the spinning mule, but in the Yorkshire twiner, the spindle carriage is stationary and the creel carrying the supply yarns moves out while twist is inserted and in while the yarn is wound on the spindles in cop form. The supply yarns can be cops, cones or other packages. The yarns can be dry-twisted, or wet doubled, in which case a trough for water or a wetting-out compound is situated between two flannel-covered drag boards.
