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; --- Part 7. whiteness; --- Part 8. ether extract content; --- Part 9. crimp performance. This section GB/T 13835 Part 1. This Part replaces GB/T 13835.1-1992 "angora fiber test sampling methods." This section compared with the GB/T 13835.1-1992 The main changes are as follows. --- Modify the method and amount of extracted sample batch and batch-like moisture regain (1992 version 4.1; this version 4.1); --- Modify the sampling method and sample laboratory test sample (1992 version 4.2 and 4.3; 4.2 edition and 4.3); Inner --- to regain a lot sample drawn into a given weight of time from within 24h 4h (version 4.1.3 1992; this version 4.1.1). This section proposed and managed by China Fiber Inspection Bureau. This section is drafted. Sichuan Provincial Fiber Inspection Bureau, Zhejiang Province Fiber Inspection Bureau, Jiangsu CIQ.

4.1 Batch comp 4.1.1 determine the number of extracted sample package Packaging Machinery 20% of the total number of sample packets; soft pack 20 bags and packages by the following extract, 20 bags by more than 30% increase in part extraction, Less than 1 in 1 package packet count; loose wool 20kg bag by 1 meter. Regain lot sample. 24-by-packet and the following package extraction; more than 24 packages randomly determined sampling Package, pumping a total of 24 bags, produce 1 sample every three kits, produced a total of eight samples, each sample of not less than 50g, respectively, into the sealed container 8 , The total mass of not less than 400g. Immediately after the release regain lot sample extraction in a closed container, and the default weight in 4h. 4.1.2 Batch extraction methods and sample quantity An open pack of multi-point method were determined from the sample package to extract even rabbit fur, like the composition of the batch, each sample package to extract the amount determined in accordance with Sample calculation package, like quality extracting batch of not less than 500g, wherein the first extraction 90g sample (in 3 parts) were placed in a sample bag for containing Miscellaneous rate and loose hair rate test, the remaining batch of samples to test for the appearance features, and then used as a laboratory sample. 4.2 laboratory sample The batch-like tiles on a test bench thoroughly mixed with a bisection into two equal parts, one for the laboratory samples, one reserved for sample preparation. 4.3 test sample The laboratory sample thoroughly mixed, multi-point method (less than 40 points) from the positive and negative sides random test sample. 4.4 Test specimens Each pilot project to extract the number of test specimens and parts shown in Table 1.
