The optimum amount of twist depends upon the use for which the yarn is intended. The amount of twist affects both the strength and elongation properties of the yarn with increased twist being associated with increased elongation

twist-tester-61

Electronic Twist tester Branca 61S measures the exact twists per unit lenght of yarns

The apparel can determine the twist no. and twist direction of single and folded yarns , monofilament yarns, multifilament yarns, Open End yarns composed of natural or synthetic fibers

Twist tester Branca 61S is designed to determine the twists per meter (tpm) or twists per inches (tpi) of all types of yarns as e.g. single, monofilament, folded yarns, multifilament yarns,Open End, spun yarns, synthetic yarns, etc..

twist-tester-61

Electronic twist-tester 61S is designed in compliance with International Standard UNI 9069, UNI EN ISO 2061, ASTM D1423, ASTM D1422 and other related norms

The reading accuracy has been improved at ± 0,1 twist and yarn sample can be tested easily setting the distance between the clamps from 1 to 50 cm in standard versions through the movable equipment installed on board or until 1 or 2 m for special models mainly used for tyre cords application, thus high-quality nylon and polyester yarns.

The electronic twist tester 61S is easy to use thanks to the user-friendly hmi touch screen that allows to select the test selection to use for the big variety of yarns:

SINGLE single yarn test means Untwist-Retwist method of single spun yarns in S or Z twist direction as described in UNI 2061, ASTM D1422;
DIRECTdirect counting test method means only untwist of yarns reaching the straight section of a yarns according to ASTM 14232/1423M;
DUALtest method suitable for double or plied yarns;
SCHUTZsuitable for Open End yarns according to the 2nd Appendix New “double test check” worked out by Messrs. M.KUENY, H.LE CHATELIER and R.A. SCHUTZ;
MANUALmotor control digitally commanded by the operator and real time read-out of real twistings;

Additional test methods are implementable only in the Twist tester 61S PRO software version:

SLIPPAGE TEST METHODtest method used to determine when yarn fiber slip off applying different pretension weights;
MULTIFILAMENT TEST METHODtest method suitable to determine the twistings no. of folded yarns up to 10 yarn levels.
GUIDED ANALYSESoperator led by the indications on the screen and test indexing, can perform multiple analysis on Single, Direct Counting, Dual, Multi-level yarns following instructions shown on display step by step;


twist-tester-ascii-printer
The test report is printed with ASCII printer supplied on request, where the operator can input data and notes as additional data, e.g.:
  • Company name;
  • Address
  • Country
  • Tension applied to yarn in grams;
  • Material
  • Sample no.
  • Notes;
  • Test results espressed in TPM or TPI;
  • Operator signature;

Test report includes additional info about:

  • Starting yarn untwist direction: S or Z;
  • Yarn length, expressed in cm or inches;
  • Saved memory up to 20 results per test method;

Other statistical evaluations:

  • Minimum;
  • Maximum;
  • Average;
  • DELTA (Max-min);
  • Coefficient of Variation (CV%);
  • Standard Deviation (ST.Dev%);

Saved results are expressed both in TPM (twist per meter) or in TPI (twist per inch).

The measure units are indicated on test report.

During the test, the HMI touch screen shows data and evaluation data, e.g.:

  • Motor speed in rpm;
  • Number of twist on real time;
  • Test index (1..20);
  • Direction of twist (S/Z or Z/S);
  • Operation commands e.g. start, stop, repeat, etc.);

statistical-analyses-software

Application software TWIST4.0: for PC use through USB serial port communication, that allows to do automatic statistical evaluations on test results, generation of trend graphs, macro plugins and math formulas;
