Commonly used raw material specifications

- Jun 05, 2017 -

The purpose of these specifications is to enable the measured specifications to be accepted by the factory. No matter what kind of raw materials, there are relatively fixed size specifications, that is, we usually call the conventional specifications. We use the estimated method to measure the size of the specifications, can not be very accurate, but to determine a general range. Therefore, after measuring the fineness of the above method, but also by the file, such as the fiber can be converted into the regular fineness, the production process can be shortened, the production cost can be reduced. The following are the conventional fineness of commonly used raw materials:

Silk filaments: 13/15 D 20/22 D 28/30 D 40/44 D

Mulberry silk double palace silk: 50/70 D 100/120 D 150/170 D

Sang silk: 210N / 2 140 N / 2 120 N / 2 80 N / 2 60 N / 2

Sang silk: 17N 25 N 27 N 33 N

Cotton yarn: 10S 16 S 21 S 32 S 42 S 50 S 60 S 80 S 100 S

          Or 32S / 2 42 S / 2 60 S / 2 80 S / 2 100 S / 2

The above doubles yarns are calculated for half of the calculation of the specifications, such as 32 S / 2 by 16S / 1

Viscose filament: 75 D 120 D 150 D

Viscose staple fiber: 10 S 20 S 30 S 40 S

Flax: 6 S 9 S 14 S 17 S 21 S 25 S

Or: 10 N 15 N 24 N 28 N 36 N 42 N

Polyester filament: 30 D 50 D 68 D 75 D 100 D 115 D 150 D 300 D

Nylon filament: 40 D 70 D 140 D

Wool: 20 N 26 N 32 N 36 N 48 N 52 N 60 N 80 N

Above for the commonly used specifications, there may be customers with conventional specifications outside the fineness, for short fibers, it is relatively easy to do, but for the filament spinning process is more complex, adjust the fineness of the higher cost, It is more difficult to meet customer requirements. In the above raw materials, the most types of polyester fiber, in addition to changes in fineness, the morphological changes are more, such as according to the gloss points are: large light silk, semi-dull filament, full extinction silk; cross section points are: round, , The three-leaf shape, bone ------ by the surface shape points are ordinary filament (drawing silk), low elastic yarn, high elastic yarn; according to single fiber fineness points have ordinary fineness (single fineness above 1.5D) (Single fiber in the 0.8D ~ 1.2D between), ultra-fine denier (single fiber below 0.8D); according to the performance of ordinary polyester and modified polyester (change dyeing performance, change the moisture absorption performance Wait). According to different products using different raw materials, such as the production of imitation silk products should be fine fine silk, the production of cashmere products (jeanette, suede, advanced equipment Sassafras) with ultra-fine denier; Wool products) with modified polyester and so on. The polyester single fiber in the raw material specifications that can also be reflected. Such as the commonly used 75 D / 36F, 75 D / 72 F, 100D / 96F, 150D / 144F. The number of "F" in these numbers indicates the number of individual fibers. 100D / 96 F represents a 100 denier (D) thickness of the wire, is composed of 96 single fibers, the single fiber fineness of about 1, generally can be called fine denier.
