3 Test principle
Under specified conditions, the sample was held constant elongation type (CRE) tensile tester holder in order to be pulled straight constant elongation
To break off from the force - elongation curve or data obtained in the data acquisition system or rupture the specimen strength, elongation, elongation strength and other fixed
Tensile properties of the measured values.
4 Sample Pretreatment
4.1 conditioning and testing using standard atmosphere. temperature of 20 ℃ ± 2 ℃, relative humidity of 65% ± 4%.
4.2 Pre for wet atmosphere. temperature does not exceed 50 ℃, relative humidity of 10% to 25%.
4.3 A sample pre-humidity control at 4.1 standard atmospheric place for more than 24h, for breaking strength and elongation test.
5 Sample Preparation
5.1 Chemical staple fiber and tow
From the quality of the sample has been made, a representative fiber extracted or interception of about 500 fibers, uniformly laid on the pile board.
5.2 bast fibers
The crack spread on the table linen quality samples from groups capable Ma, slightly folded at the cut, again clipping base 10cm, mixed by comb
