yarn

In the manner known to those skilled in the art of textiles, yarns are used with irregular diameter goods with desired aesthetic and gripping properties available. Under the yarn with irregular diameter or "knobbed yarn" is to be understood here a yarn that is light detectable, bulky parts (coarsening or Has "knobs") at least 0.64 cm long »

Silk yarn with irregular diameter are known to be quite valuable, but are, as they are obtained from abnormal cocoons _s not in · the large quantities and consistent quality are available which are required for the mass production of goods made of such yarn.

The titer ratio is the ratio of the> titer of the thickening to the titer of the base yarn. "Au understand / The mean titer ratio is determined by" determining the titer ratio of all thickenings in a yarn sample of a given length (e.g. 1400 m) _;; and the mean is calculated. The titer ratio of a given. Thickening ν naturally represents a mean value, since the titer of a thickening typically varies over its entire length «" ■ ■.. · "'-" · " ^: ' - ^Λ . ^: . ^: '-
