Foreword

GB/T 29256 "Textiles - Woven fabrics structure analysis method" includes the following sections. Part 1. Figure and heald weave, mechanized representation of FIG denting and lifting; Part 3. yarn in fabric shrinkage measurement; Part 4. Determination of twist in yarn removed from fabric; Part 5. Determination of linear density of yarn removed from fabric; Part 6. Fabric weft yarn mass per unit area was measured. This section GB/T Part of 529,256. This section drafted in accordance with GB/T 1.1-2009, rules GB/T 20000.2-2009 given. GB/T 29256 "textile fabric structure analysis machine" section above and the corresponding part of ISO 7211 series of standards corresponding. And ISO 7211 Part 2 corresponding to the national standard GB/T 4668-1995 "Determination of density woven fabrics", GB/T 4668- 1995 referring to the use of ISO 7211-2. 1984 developed. This section uses redrafted Law Amendment uses ISO 7211-5. 1984 "Textiles - Woven fabric structure analysis method - Part 5. Determination of yarn removed from fabric linear density. " Part of this ISO 7211-5. 1984 The main differences are as follows. --- Remove the introduction, into the scope of its content; --- Increased range and does not apply content; --- Normative references are replaced by the corresponding international standards to national standards; --- Simplified description number of specimens, the length of the note in the sample was adjusted to 250mm, incorporated in the text; --- The measurement procedure combined into Chapter 7; --- Specify oven heated to 105 ℃, weighing interval unified 30min; --- Increased by 7.3 and 8.3 of the measurement strand linear density and representation terms; Interpretation --- In the formula (3) in combination to increase the drying value of moisture regain factor; --- Test report adds "sample description." This part is proposed by the China Textile Industry Association. This part of the National Textile basic standards Standardization Technical Committee Technical Committee (SAC/TC209/SC1) centralized.

1 Scope

GB/T 29256 provisions of this part of the determination of linear density of yarn removed from fabric comprising fibers from the material did not go unless Determination of linear density of yarn removed from fabric, as well as from the measurement method to remove non-woven fabric material that has been removed yarn linear density. This section applies to most of the woven fabric does not apply in certain straight crimped yarn tension can not be eliminated, as well as weaving, finishing The method and analysis process by yarn fabric damage. Note. the method of the area of \u200b\u200bthe resulting fabric may be a yarn linear density of the yarn before weaving linear density different from the original.
