Foreword
GB/T 13835 "rabbit fiber test method" consists of the following nine sections.
--- Part 1. Sampling;
--- Part 2. The average length and short hair ratio manual transmission method;
--- Part 3. impurity rate, coarse hair and loose hair rate;
--- Part 4. Regain oven method;
--- Part 5. single fiber breaking strength and elongation at break;
--- Part 6. diameter projection microscopy;

This section GB/T 13835 Part 6.
GB/T 13835.6-1992 "angora fiber fineness test methods" in this section instead.
This section compared with the GB/T 13835.6-1992 The main changes are as follows.
--- Measuring step by the 1mm modified to 0.5mm (version 7.4.2 1992; this version 8.1.1);
--- Increased detection order schematic arrows and legend (1992 version 7.4.2; 8.1.1 edition);
--- Rate differences between the two test samples of 5% revised to 3% (1992 version 7.4.5; 8.1.4 edition);
--- Improving the focusing and measuring record text description (version 7.4.3 1992; this edition 7.2 and 8.2);
--- Modify the test result is calculated (version 1992 Chapter 8; Chapter 9 of this edition);
--- Modify numerical rounding (Version 1992 Chapter 9; Chapter 10 of this edition).

GB/T 13835.1 rabbit hair fiber test methods - Part 1. Sampling
Principle 3
The outline rabbit hair fiber segments magnified image projected on the screen, with a ruler to measure fiber diameter wedge screen inside the circle, successive record measurements
Fruit, and calculate the average fiber diameter.
4 apparatus and appliances
4.1 projection microscope.
4.2 pairs or fiber blade slicer.
4.3 slides, cover slips.
4.4 sealing medium. liquid paraffin, or a temperature of 20 ℃ refractive index of the liquid medium from 1.43 to 1.53.
5 Standard conditioning and testing atmosphere
5.1 presetting wet
The test sample was allowed to stand at a relative humidity of 10% to 25%, the temperature does not exceed 50 ℃ atmospheric conditions, bringing them closer to equilibrium. If the test
Regain equilibrium moisture content of the sample is higher than the standard (14%), the need to pre-process the humidity.
5.2 Standard conditioning and testing atmosphere
Standard atmosphere in GB/T 6529 provisions (a temperature of 20 ℃ ± 2 ℃, relative humidity of 65% ± 4%) were conditioning and testing,
The humidity not less than 2h.
6 Sampling and sample preparation
6.1 Sampling
According to GB/T 13835.1 provisions of the thoroughly mixed laboratory sample tile on the table, with the pros and cons of each 16-point multi-point method
Draw about 30mg test sample, divided into three parts of the test sample.
6.2 Sample Preparation
6.2.1 Each test will be compiled into a parallel sample of small bundles, fiber or dual-blade slicer in the middle of the fiber cut sample cut
