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 629,256.

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 7211-6. 1984 "Textiles - Woven fabric structure analysis methods - Part 6.

Weft yarn quality measurement area "fabric units.

Part of this ISO 7211-6. 1984 The main differences are as follows.

--- Deleted the introductory part;

--- Normative references are replaced by the corresponding international standards to national standards;

--- Increased range and does not apply content;

--- A simplified description of the principle of the method;

--- Results The calculation of "accurate to one decimal place";

--- Test report adds "sample description."

1 Scope

This section GB/T 29256 provides for two methods of fabric per unit area of \u200b\u200bthe warp and weft of quality, it may be necessary

One.

This section applies to most fabrics, yarn does not apply to easily remove the fabric.

Principle 3

Method A. the sample draw a rectangle marked on the fabric samples tested, unless after the fibrous material to decompose remove warp and weft were measured

Its quality.

Method B. the known area of \u200b\u200bsample decomposition, remove the warp and weft, warp and weft yarn from going after unless fibrous material were measured quality.
