The twisted color silk is yellowed. 3.3 Unconstrained crimpunevenness In the process of processing, due to poor untwisting, the local non-bulked tight strands or the local twisted strands are insufficient. 3.4 Bamboo silk bambooknoppedfilament The strands are tightly twisted, and the twists are concentrated every 2 cm to 5 cm along the length of the textured yarn to form tight details or tight points. 3.5 Single stranded silkstrandfilament The sericin is sandwiched by a strand or a layer of silk which is left as a result of a strand break in the process. 3.6 Multiple silks excessivefilaments Since the drafting drum is a double-twisted yarn for false twisting or a tow that is entrained into the adjacent spindle when twisted, the linear density of the strand is significantly thicker. The silk layer or the entire filament is twisted.4 Classification and identification4.1 According to the content of titanium dioxide, the product can be divided into light wire, semi-dull wire and full extinction wire. 4.2 Product specifications are expressed in terms of bus density (dtex) and number of filaments (f).

The method is applicable to the polypropylene elastic yarn produced by the false twist deformation process. B.2 Normative references The following documents are indispensable for the application of this document. For dated references, only dated versions apply to this article. Pieces. For undated references, the latest edition (including all amendments) applies to this document. GB/T 6502 chemical fiber filament sampling method GB/T 6529 Standard atmosphere for textile conditioning and testing GB/T 8170 Numerical Rounding Rules and Representation and Determination of Limit Values B.3 Principle After the sample was treated under the specified conditions, the length under light and heavy load conditions was measured, and the elongation at break and the elastic recovery rate were calculated. B.4 Instruments and equipment B.4.1 Vertical scale. length is 0.5m~1m, and the division value is 1mm. There is a holder at the upper end, the lower end of the holder and the measuring ruler The zero position is flush. B.4.2 Tension clamp. The mass is calculated according to the nominal linear density, the light load is 0.0018cN/dtex, and the heavy load is 0.1cN/dtex. B.4.3 Electrothermal constant temperature water tank, stopwatch, oven, etc. B.5 Test procedure B.5.1 According to GB/T 6502, 20 wire strands are obtained, and each wire strand is cut into two curls of 30cm~40cm. B.5.2 Pre-treat the silk sample in constant temperature water at a temperature of (70 ± 2) °C for 30 min. B.5.3 Take the hot-treated silk sample and place it loosely on the dry skim gauze. The standard specified in GB/T 6529 Allow to dry naturally for 12 h under quasi-atmospheric conditions, or put in a standard atmosphere strip specified in GB/T 6529 after being baked in an oven at a temperature of 45 ° C for 30 min. The mixture was equilibrated for 2 h to achieve a moisture absorption balance. B.5.4 Clamp the balanced wire sample into the holder at the upper end of the vertical measuring rule, let it hang naturally, and then load the light load at the lower end. The force clamp causes the wire to hang. After 30 s, the wire sample is marked with a mark (M point) at a vertical gauge of 20 cm, which is the initial length L0, accurate to 1 mm. B.5.5 Remove the light load tension clamp, and then clamp the heavy load tension clamp. After 30s, observe the vertical scale of the M point at the same level. The degree is the length L1 when the load is increased, to the nearest 1 mm. B.5.6 Remove the heavy-duty tension clamp, and slowly retract the wire sample for 2 minutes, then add the light load tension clamp. After 30 seconds, observe the M point at the same level. The vertical scale is the recovery length L2 when the heavy load is removed and the light load is removed, to the nearest 1mm. B.6 Calculation of results The contraction elongation and elastic recovery rate are calculated according to formula (B.1) and formula (B.2). CB=L1-L0L0 × 100% (B.1) SR=L1-L2L1-L0× 100% (B.2) In the formula. CB --- tightening elongation, %; L1 --- length of the weight load, in centimeters (cm); L0 --- plus light load length in cent......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of FZ/T 54009-2012_English be delivered?Answer: Upon your order, we will start to translate FZ/T 54009-2012_English as soon as possible, and keep you informed of the progress.
