Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
"Determination of linear density and export of cotton, polyester-cotton woven fabric" Instead of the standard SN/T 1013-2001.
This standard compared with SN/T 1013-2001, the main technical changes are as follows.
a) determination of the yield point of the yarn, this standard is omitted empirical formula SN/T 1013-2001Y value, standard yield
From the point of yarn tester at a certain tension, promote test clip, drawn yarn to yarn into three meter line, the measured bending stretch
Long length of the yield point;
b) for determining the pre-tension, the standard gives two methods, one is in the body of the standard quoted ASTMD1059-01 Regulation
Given that the measured yarn linear density estimates, according to 0.25cN/tex without first giving the first pre-tension using yarn Measurer
It has curved elongated length, and then follow the linear density of the first measured bending elongated length representation, according to 0.25cN/tex then give
The exact tension, then the yarn meter measured the bending of the second extension length. Second, the standard normative appendix, references
Type constant elongation (CRE) testing machines, relaxation of the yarn is pre-drawn, according to the force - elongation curve determined pre-tension,
To determine the length of the curved elongated;
c) According to the actual work needs, make fast humidity control method;
d) cut the sample is determined as 200mm × 200mm2 block, to extract the number of each yarn is determined to be 20.
This revised standard adopts the American Society for Testing and Materials standard ASTM D1059-01 "StandardTestMethodforYarn
NumberBasedonShort-LengthSpecimens1.Scope, 10procedure and 11.Calculation bar.
This standard is proposed and managed by the National Certification and Accreditation Administration Committee.
This standard was drafted. People's Republic of China Shanghai Entry-Exit Inspection and Quarantine Bureau, Ministry of Education Key Laboratory of textile fabrics (Donghua large
learn).
The main drafters of this standard. Chen Qingdong, Zhang Ning, Wang Jun, Zhao Jie.
This standard was first released in 2001, in 2010 the first amendment.
Determination of linear density of yarn in woven fabrics Importers
Cotton, polyester woven fabrics
1 Scope
This standard specifies the determination of linear density woven fabrics principles, instruments, reagents, sample preparation, test procedures, calculations and test reports.
This standard applies to the determination of cotton, polyester-cotton woven fabric linear density. This section does not apply to the knitted fabric, pure chemical fiber and other technology integration by terry
Special-treated fabric.
2 Normative references
