a yarn produced by combining one fibre or filament with another during a
twisting process.
a measure of linear density (see decitex, denier, tex).
a yarn made by feeding one yarn through one or more revolving spindles
carrying the other (wrapping) yarn. Covered yarn may also be produced using
air-jet technology.
a number which indicates the extent to which the area of a knitted fabric is
covered by yarn. It is also an indication of the relative looseness or tightness
of the knitting.
a number which indicates the extent to which the area of a fabric is covered
by one set of threads. For any woven fabric, there are two cover factors: a
warp cover factor and a weft cover factor. Under the cotton system, the
cover factor is the ratio of the number of threads per inch to the square root
of the cotton yarn count.
a unit of the tex system. A measure of linear density; the weight in grams
of 10,000 metres of yarn.
the average decitex of each filament in a multifilament yarn.
a synthetic polymer with a tree-like branching structure.
a measure of linear density; the weight in grams of 9,000 metres of yarn.
a layer in a nonwoven hygiene product (such as a diaper) which distributes
fluid to a superabsorbent and/or fluff pulp material, where it is absorbed.
a mechanism for controlling the vertical position of heald shafts on a loom,
so as to selectively raise some warp threads while leaving others depressed.
The use of a dobby facilitates the weaving of a fabric which has a more
complex structure than that achievable by using cams and tappets to raise and
lower heald shafts. However, it can not offer weaves as complex as those
obtained by using a jacquard mechanism.
a type of weave produced on a loom equipped with a dobby.
see decitex per filament.
a cover sheet.
in the dry spinning process, polymer is dissolved in a solvent before being
spun into warm air where the solvent evaporates. This leaves the fibrous
polymer ready for drawing.
a fibre or filament produced by the dry spinning process.
see decitex.
