Preface FZ/T 12047-2014 Details of Cotton/Water Soluble Vinylon Natural Color Thread FZ/T 12047-2014.1 Scope FZ/T 12047 specifies the terms and definitions of cotton/water soluble Vinylon natural color thread products, as well as product classification. Marking, requirements, test methods, inspection rules and markings, packaging. FZ/T 12047 is suitable for the combination and reverse twisting of pure cotton single yarn and water-soluble vinylon single yarn, allowing the cotton yarn to fully break down the twisted natural color thread. The following normative references are essential for the application of this document. For dated references, only the dated version applies to this document. For undated references, the latest version (including all modification orders) applies to this document. GB/T 398-2008 Cotton Yarns of Natural Color GB/T 2543.1 Determination of Twist in Textile Crystal Yarns Part 1: Direct Counting Method GB/T 2543.2 Determination of Twist in Textile Crystal Yarns Part 2: Untwist and Twist Method GB/T 3292.1 Test Method for Unevenness of Textile Yarns Part 1: Capacitance Method GB/T 3916 Determination of Breaking Strength and Elongation at Break of Single Yarn in Wrapped Yarns GB/T 4743-2009 Determination of Linear Density in Wrapped Yarns GB/T 30101-20 13 polyvinyl alcohol water-soluble short fiber FZ/T 10007 cotton and chemical fiber pure spinning. Inspection Rules for Blended Natural Color Yarns FZ/T 1008 Cotton and Chemical Fiber Pure Spinning. The following terms and definitions apply to the marking and packaging of blended natural colored yarns in this document. 3.1 Water soluble polyvinyl alcohol (PVA) fiber is modified from polyvinyl alcohol (PVA) fibers, which can fully dissolve in water at a constant temperature. 4 Product classification. Mark 5 Requirement 5.1 The technical requirements for the cotton/water-soluble vinylon natural color yarn of the project include the coefficient of variation of single line breaking strength, coefficient of variation of linear density, and single line breaking strength. Linear density deviation rate, evenness variation coefficient of yarn, kilometer nep (+200%), and twist variation coefficient of strand yarn. 5.2 Classification regulations 5.2.1 Products of the same specification produced continuously from the same raw material and process shall be considered as one or more inspection batches. 5.2.2 The product quality level is divided into first-class products, first-class products, and second-class products. Products below second-class are considered substandard. 5.2.3 Cotton/water-soluble vinylon natural color yarn products shall be rated based on the product specifications and the lowest item in the assessment items, and the grade of cotton/water-soluble vinylon natural color yarn products shall be evaluated based on the results. 5.3 Technical Requirements: The technical requirements for cotton/water-soluble vinylon natural color yarn shall be as specified in Table 1
