1 Cocoon
The envelope of raw silk spun by the silkworm and in which it encloses itself when in the pupa state. About 10 per cent of the totalled weight can be reeled off in a single filament, the length averaging about 300 yards. The outer layers of the cocoons are used for floss or spun silk. -
2 Cocoon Pointus
Cocoons which have one end rising in a point. When reeling, the thread breaks at the point where the thread is weak, and so cannot be wound further (see Raw Silk) -
3 Bad Cast
Classified as a "major" defect by the Silk Association of America. Casts are the beginning of new cocoon filaments. Appearance - Abruptly increased diameter in a raw-silk thread. This defect may vary in length. Causes - A single cocoon filament may not have been properly " cast " on to the raw-silk thread in the reeling operation; or a " layer " of filaments may have loosened itself from the cocoon and have come off the cocoon simultaneously by passing through the rollers porcelain gauge-eyelets in a bulk, which either suddenly or gradually decreases to the required number of single cocoon filaments - that is, to the normal size of the raw-silk thread. -
4 Antherea
Several commercial varieties of wild silks are obtained from the silkworms as under. These worms do not feed on mulberry leaves, and because of this fact are called wild silks: - Antherea Yama-Mai - A native of Japan which feeds on oak leaves. The caterpillar is green-coloured - its cocoon is large and bright green. The fibre is not so readily dyed and bleached as Bombax mori. Antherea Pernyi - A native of China, feeding on oak leaves. The cocoon is large and of a yellow to brown colour. Antherea Assama - A native of India, giving a large cocoon. Antherea Mylitta - A native of India (see Antherea Silk) -
5 Corkscrews
Officially classified as a major defect by the Silk Association of America. The appearance is spiral like raw silk thread, instead of smooth and cylindrical. It may seem thinner or coarser in size, but this may prove to be only an illusion. The spirality runs for varying lengths. It is caused in the reeling operations by some cocoon filaments having become unevenly tensioned, or a cocoon filament may have broken and been tied or pieced with the tails not cut so that the tails may have attached to the thread in the reeling in spiral like fashion on to the raw silk thread; this defective portion of the thread is called corkscrew. -
6 Antherea Silk
A term often applied to the silk produced by the Antherea mylitta, a wild silkworm of India, which gives the so-called tussah silk. The worms feed on the leaves of the castor-oil plant, and give very large cocoons. The fibre is much longer than from the cocoon of the Pombyx mori, varying from 600 to 2,000 yards in length. The colour of tussah silk varies from a grey to a deep brown. Other wild silks are also frequently given this name (see Antherea) -
7 Basinetto Silk
Waste silk obtained from the hard inner skin of the cocoon, which was left over after the reeling. Also known as Ricotti, Neri, Galettame Silk. -
8 Bassinas Silk
A waste silk obtained from the cocoon after reeling, used for floret silk. -
9 Bave
When silk is reeled from the cocoon a double filament is drawn: out and this.. is termed " Bave." The length varies from 400 to 1,000 yards. The single filament is given the name " Brin." -
10 Cappadine Silk
The silk floss obtained from the cocoon after the good thread has been reeled. The yam spun from this waste is used for carbaso and laffis cloths. -
11 Corean Silk
Brand name for a piece-dyed douplon silk of medium weight, double cocoon filling. -
12 Crin Silk
The silk substance obtained from the glands of dead silk worms; it is heavier than cocoon silk. -
13 Dumb Singles
A silk trade term for yarns made from cocoon filaments, reeled without twist, which are combined to form tram or thrown silk weft. The finest of silk yams. This term is also applied to rayon and other untwisted yarns. -
14 Dupion (Double)
A silk trade term denoting a double cocoon formed by two or more silkworms. -
15 Duvet
Imperfections in reeled silk consisting of small loops which are formed by the fibre (bave) as drawn from the cocoon. -
16 Frison Silk
Irregularly spun and tangled silk on the outside of cocoons which have been pulled slightly loose and are generally heavier in earthy matter. It comprises from 25 to 30 per cent of the entire cocoon and is valuable. -
17 Galettame Silk
Waste silk obtained from the inner skin of the cocoon which is left over after reeling. It is also known as ricotte, wadding, neri and basinetto silk. -
18 Hairiness
A condition of silk threads due to countless fibres of fragmentary size having been broken off the individual cocoon filaments. This condition is also known as lousiness or fuzziness. -
19 Husks
-
20 Kemuka Silk
Silk waste in Japan, obtained from the outer skin of the cocoon in reeling.
