Foreword

Accordance with the standards GB/T 1.1-2009 given rules drafted Instead of the standard FZ/T 71005-2006 "The knitted cotton yarn." this standard FZ/T 71005-2006 compare the main changes are as follows.

--- Revised Chapter 3 classification will be calculated 100m standards of quality and standards into the dry mass of Appendix A, delete the line density to Demand content;

--- Technical requirements, modify the name of part of the project, evenness assessment remains only evenness variation coefficient, blackboard Nep tune Whole in kilometers Nep assessment;

--- Yarn breaking strength of the coefficient of variation, linear density coefficient of variation (the original "one hundred meters weight coefficient of variation"), yarn breaking strength, linear density Deviation ratio (the original "one hundred meters weight deviation"), evenness variation coefficient and other indicators have been adjusted;

--- Cancel indicators along the lower assessment, according to the technical requirements of the products, such as a minimum assessment;

--- Change the original sample, adjusting the direct sampling of the finished product.

The standard proposed by China Textile Industry Association.

3 Product classification, marking

3.1 The cotton knit with yarn in different production processes and line density classification.

3.2 The knit cotton yarn raw cotton, code-named C, combing production technology, code-named J, knitting yarn codenamed K.

3.3 knitted cotton yarn when this mark, after the front line density should indicate yarn production process code, material code, line density indicated pin Weaving yarn code.

Example. a linear density of 18.5tex combed cotton knit with this yarn, should be written as. JC18.5texK.
