Scope

This part of GB/T 3917 specifies a method for determining the tear strength of a fabric using a single slit pant sample method. In the direction of tearing strength
The force required to tear the fabric from the initial single slit slit to the specified length is measured.
This section is mainly applicable to woven fabrics, and can also be applied to fabrics made by other technical methods, such as non-woven fabrics.
This section does not apply to knitted fabrics, woven elastic fabrics, and sparse fabrics that have the potential to cause tear transfer and have higher anisotropy.
Fabric.
This section specifies the use of a constant velocity elongation (CRE) tester.

Summary	This standard specifies the method for determining the fabric sample with a single slit trouser tear strength of the law. Tear strength of the fabric measured in the direction from the initial single tear slit to a predetermined length of the incision required force. This section applies to woven fabrics, fabric can also be applied in other manufacturing technical methods, such as non-woven cloth. This section does not apply to knitted fabric, woven elastic fabric and tearing the fabric may produce sparse transfer fabric and has a high anisotropy. This section provides the use of constant elongation (CRE) tester.
