ASTM-D-1422 Electronic Textile Digital Yarn Twist Tester

Product Introduction

Determining optimum twist is critical for yarn physical characteristics. Yarns with low twist counts produce increased softness for knitting and warmth, while higher twist counts provide additional tensile strength. However, maximum tensile strength decreases if the twist angle exceeds the desired amount.

The SBT331A Electronic Digital Twist Tester meets international standards for measuring both untwist/retwist and direct rotational counting methods, offering advanced technology that is easy to use and cost-effective.

Applications

Designed to determine yarn twist in single or plied yarns using quadrant type with auto stop & reverse for conventional or untwist/retwist methods.

Testing Standards Compliance

ASTM D1422 - Standard Test Method for Twist in Single Spun Yarns by the Untwist-Retwist Method
ASTM D1423 - Standard Test Method for Twist in Yarns by Direct-Counting
ISO 2061 - Textiles - Determination of twist in yarns - Direct counting method
BS 2085 - Method of test for determination of twist in yarns, direct counting method
DIN 53832 - Testing of textiles - Determination of the twist of single and plied yarns

Test Procedure

Select the appropriate method/mode
Clamp yarn between two clamps
Select 'S' or 'Z' key based on twist direction
Set stopper at approximately 50% of expected elongation
Press 'START' key to initiate motor
Motor untwists yarn while LCD display counts twists

Salient Features

Latest microprocessor-based equipment for twist per inch/cm measurement
Specialized for single yarn, double yarn & open-end yarns
Special sensor for zero setting
Tensioning device for proper yarn tension during testing
Fully programmable unit
User-friendly control panel with operator guidance
Smooth precision-engineered auto mechanism
1 to 50gms weights for proper tension application
Digital control panel with 16-character, 4-line LCD display
