Embodiment

[0038] Example Blind Fabric Test Example

[0039] A piece of woven fabric A with unknown nominal linear density (cotton-type yarn, without coating and other non-fibrous substances, single yarn, actual specification is 21s×21s, take this sample as a blind fabric test, and compare the test results with the specifications ), it is required to test the yarn linear density, the test procedure and results are as follows.

[0040] 1 Sample preparation

[0041] Since the samples do not contain non-fibrous substances such as coatings, no pretreatment according to ISO 1833-1 is required. Place the sample in a constant temperature and humidity chamber and adjust the humidity to the equilibrium state specified in GB / T 6529.

[0042] 2 Approximate value of test yarn linear density

[0043] The two ends of the yarn removed from the fabric are respectively clamped into the two clamps of the yarn length tester, and the two clamps are separated without straightening tension until the curl o...

Abstract

The invention discloses a linear density test method of a withdrawing yarn of woven fabric for the linear density under an unknown name of the yarn, which comprises the steps of: firstly, measuring a general value of the linear density of the yarn to determine the extending tension during the length measurement by a yarn length measuring instrument; then testing the length and quality of the yarn; and calculating the linear density of the yarn. The test method is simple, accessible, practical and efficient in test operation, is simple and convenient to inspect and operate, short in the inspection period, and has high operability.

Description

technical field [0001] The invention belongs to the technical field of textile testing, and in particular relates to a method for testing the linear density of a woven fabric whose nominal linear density is unknown. Background technique [0002] Enterprises purchase knitted products according to a certain specification, how to verify whether the product meets the requirements, some indicators such as yarn branch density, there is no corresponding method standard. The test of the linear density of woven fabrics has a corresponding test standard, that is, "FZ / T01093-2008 Woven Fabric Structure Analysis Method - Determination of the Linear Density of Yarns Removed from Fabrics". [0003] According to the FZ / T01093-2008 standard for measuring the linear density of yarns removed from woven fabrics, according to FZ / T01091-2008 "Measurement of Yarn Weaving Shrinkage in Fabrics by Structural Analysis of Woven Fabrics", calculate the stretch that needs to be set to measure the length...
