The splice strength tester launched by Pioneer Instruments & Innovations in ITME 2008 is an advanced tester which tests the retained splice strength of a splicer. In addition to it, this instrument also gives the tenacity in g/tex (RKM) of the yarn being tested.
Need for testing splice strength
All modern mills deploy autowinders at huge costs to wind the cops into cones. The primary idea of employing autowinders is to produce good quality yarn with minimum man-power. Splicers are an integral part of any autowinder. The Splicer should splice the yarn at every break with at least 75 to 80% strength of the parent yarn. If they don’t do so then the yarn produced by such splicers will create enough problems for the subsequent end user irrespective of what its other quality parameters may be (like RKM, CSP, evenness, etc.). Hence even a very good quality ‘A’ grade yarn may be a failure with the end user if the splice strength is not sufficient. Hence every splicer should be monitored periodically for splice strength.
Conventional splice strength testing method
The conventional method of testing splice strength was to test the parent yarn and spliced yarn using a pull gauge. This method was very approximate and operator oriented errors where large. Hence it was a failure in most of the mills.
