DENIER
Do you like this story?
Denier or den is a device of evaluate for the immediately line huge solidity of fibres. It is scheduled as the huge in h per 9,000 measures. In the Worldwide Method of Models the tex is used instead (see below). The denier is according to a normal standard: 1 string of cotton is one denier. A 9,000 gauge string of cotton weighs one g. The phrase denier is from a France money of little value (worth 1/12 of a sou). Used to string, a denier was presented to be equivalent in fat to 1/24 oz (this does not have units of huge per length!).
The phrase micro-denier is used to explain filaments that think about less than one g per 9,000 gauge duration.
One can identify between Filament and Complete denier. Both are identified as above but the first only concerns 1 filament of fiber content (also usually known as Denier per Filament or D.P.F) whereas the second concerns a string, an agglomeration of filaments.
The following connection relates to immediately, consistent filaments:
D.P.F. = Complete Denier / Variety of Uniform Filaments
The denier system of description is used on two and individual filament fibres. Some typical data are as follows:
1 denier = 1 g per 9 000 meters
= 0.05 h per 450 measures (1/20 of above)
= 0.111 mg per meter
In exercise calculating 9,000 measures is both time-consuming and bad. Usually a example of 900 measures is assessed and the outcome increased by 10 to acquire the denier fat.
A fiber content is usually regarded a micro-fiber if it is 1 denier or less.
A 1-denier rayon fiber content has a size of about 10 micrometers.
Denier is used as the evaluate of solidity of place in hose and tights, which identifies their opacity.
One can determine the size of a filament given its fat in denier with the following formula:
where ρ symbolizes the material's solidity in h per cubic centimeter and the size is in cm.
