SN/T 3588-2013Determination of linear density of yarn removed from the knitted fabric (English PDF)

Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules.

This standard is proposed and managed by the National Certification and Accreditation Administration Committee.

This standard was drafted. People's Republic of China Jiangsu Entry-Exit Inspection and Quarantine Bureau.

1 Scope

This standard specifies the determination knitted yarn removed from the line density test method.

This standard applies to most of the knitted yarn removed Determination of linear density, does not apply on certain straight yarn tension can not be eliminated it curled, or can not be split, and fabric weaving, finishing and the method of analysis of yarn damaged.

Note. The use of this standard methods of knitted yarn linear density may be the front line of the original yarn weaving different densities.

Principle 4

Remove from the sample yarn, measuring its stretched length and quality, where quality standards in the quality of the humidity in the atmosphere after the test, or Drying quality. Calculated based on the quality and yarn count stretched length.

In the determination of the dry mass of the yarn, when heated to 105 °C, easily volatile substances other than water caused significant losses in this case should be Sample standard air quality was measured after the humidity.

You can not go unless yarn fiber material was measured to be on the go unless yarn fiber material was measured.
