Foreword

This standard replaces GB/T 6099.1-1985 "Test method for maturity of cotton fiber cell wall in the cavity contrast method" and GB/T 6099.2- 1992 "Test method for maturity of cotton fiber polarization meter method." The main changes modified as follows. --- The GB/T 6099.1-1985 and GB/T 6099.2-1992 consolidated into a standard; --- According to GB/T 1.1-2000 write requirements, modification of the cover and write formats, increasing the foreword, scope and normative references file; --- Original standard GB/T 6099.1-1985 Test specimen observation each 180 ~ 220 to each test specimen observation is not Less than 180; --- Revised GB/T 6099.1-1985 and GB/T 6099.2-1992 The test report format. Appendix A of this standard is an informative annex. This standard was proposed by the State Administration of Quality Supervision, Inspection and Quarantine.

1 Scope

This standard specifies the method according to the cotton fiber cell wall cavity polarization contrast method or apparatus method to determine the maturity of cotton fiber maturity. This standard applies to upland cotton, long-staple cotton and an untreated cotton yarn, cotton fiber line release after maturation factor, maturity ratio, mature Fiber percentage test.

3 Terms and Definitions

The following terms and definitions apply to this standard. 3.1 Cotton fiber cell wall relative to the degree of development. 3.2 The actual cotton fiber cross-sectional area of \u200b\u200bthe cell wall area of \u200b\u200ba circle with the same perimeter ratio. 3.3 Cotton fiber cell wall thickness increased to 0.577 arbitrarily selected equal to the increase in the standard thickness ratio. 3.4 The average percentage of mature fibers comprise fibers of the total number of roots. 3.5 It represents an indicator of the cotton fiber maturity. According to the Department of the ratio of cotton fiber cell wall thickness and cavity width fixed for the corresponding value. ratio The smaller the coefficient, the greater maturity, represents the more mature fibers. 3.6 Lateral wall thickness by optical microscope observation cotton fiber convolutions flattened segment. 3.7 Lateral observation through an optical microscope cotton fiber convolutions flattened sections of wall remaining cavity width.
