Yarn density measurement method of single yarns disassembled from piled yarns in fabric

Abstract

The invention provides a yarn density measurement method of single yarns disassembled from piled yarns in fabric and relates to the technical field of yarn density measurement of textiles. Through lots of tests and by statistics of quality deviation rate of a higher quality value and a lower quality value of two single yarns, it is determined that yarn densities of two single yarns are different when the quality deviation rate is greater than 10%, and piled yarn density is indicated as the sum of yarn densities of the two single yarns; and when the quality deviation rate is less than or equal to 10%, the two single yarns have the same yarn density, and the piled yarn density is indicated as two times of the single yarn density. Finally, calculation and expression method of the test results is determined, the blank of yarn density detection method of yarns disassembled from piled yarns in fabric is filled up, and technical support is provided for the detection of piled yarn density of fabric. If the method is universally adopted, the invention provides a scientific accurate unified examination method for a detection mechanism and also improves processes for enterprises. The method provides a basis for inspection of a product required by the client and also helps raise quality detection accuracy. The method has important social and economic benefits.

Description

technical field [0001] The invention relates to the technical field of measuring the linear density of textiles, in particular to a method for measuring the linear density of a single yarn by removing strands from a fabric. Background technique [0002] In trade, it is usually necessary to specify the linear density of the yarns in the fabric, and the linear density of the warp and weft yarns in the fabric is an important reflection of the fabric specifications and quality indicators. Therefore, the single yarn density test method for removing the strands in the fabric is formulated , It is of great significance to maintain the normal progress of trade and reduce trade disputes. [0003] In recent years, the share of high-end textiles has increased, and the inspection of fabric linear density has become more and more important. However, the current domestic fabric linear density index inspection method is GB / T29256.5-2012 "Textile Woven Fabric Structure Analysis Method No. ...

[0003] In recent years, the share of high-end textiles has increased, and the inspection of fabric linear density has become more and more important. However, the current domestic fabric linear density index inspection method is GB / T29256.5-2012 "Textile Woven Fabric Structure Analysis Method No. Part 5: Determination of the Linear Density of Disassembled Yarns in Fabrics", this method does not make clear instructions on the inspection of strand fabrics, especially the determination of the single yarn density of the strands

The international standard has ISO7211.5-1984 "Determination of Yarn Linear Density Removed from Fabric". In addition, what is reported at home and abroad is to study the change of yarn density after yarn is woven into fabric, and there is no report. The method of detecting the single yarn density when the fabric is removed from the strands
