Testing of Natural Color Yarn Blended with Carding Cotton and Copper Ammonia Fiber

Preface FZ/T 12054-2017 Details of Plain Carding Cotton and Copper Ammonia Fiber Blended Natural Color Yarn FZ/T 12054-2017.1 Scope FZ/T 12054 specifies the classification, marking, requirements, test methods, inspection rules, and markings of Plain Carding Cotton and Copper Ammonia Fiber Blended Natural Color Yarn. FZ/T 12054 is suitable for ring spinning plain carded cotton and copper ammonia fiber blended natural color yarn. The following documents are essential for the application of this document, which are not applicable to special purpose carded cotton and copper ammonia fiber blended natural color yarn. All cited documents with issue 8 noted. The dated version only applies to this document. For undated references, the latest version (including all modification orders) applies to this document.

Blended natural color yarn labeling and packaging 3 product classification. Mark 3.1 Plain combed cotton and copper ammonia fiber blended natural yarn products are classified according to different blending ratios and linear densities. 3.2 Raw material code for natural color yarn blended with carded cotton and copper ammonia fiber; Copper ammonia fiber is Cu, and cotton is C.3.3. The blending ratio of the product is expressed by the public quality ratio, specifically as: the cotton blending ratio is 50% or more. Expressed as cotton content/copper ammonia fiber content; The mixing ratio of cotton is below 50%, expressed as copper ammonia fiber content/cotton content. Example: The natural color per second linear density of the blend of back planting cotton and copper ammonia fiber is 18.5 tex. The copper ammonia fiber dimension is 65%. The cotton content of 35% should be written as Cw/C 65/35 18.5 tex. Note. The cumulative number of sand line imperial branches and Tex conversion is 590.5. 4. Requirement 4.1 The technical requirements for the blending of plain carding cotton and copper ammonia natural color yarn in the project include the deviation rate of linear density. Coefficient of variation in linear density, single yarn breaking strength. Single yarn breaking strength variation coefficient and evenness variation coefficient. Kilometer details (-50%), kilometer thick knots (+50%). Dry rice cotton thread (+200%), 100000 meter yarn defects, and fiber content deviation+indicators
