Testile Testing Equipment

The Digital Ink Rub Tester is designed to measure scuffing or rubbing resistance. Several tests can be performed including dry rub(the amount of transfer ink from one dry surface to another), wet rub(the amount of transfer of ink from wetted surface to another), wet bleed or transfer (ink transfer to a water-saturated blotter), wet smear(similar to wet bleed with the addition or rub cycles), functional rub/wet rub(smear or transfer tests using a liquid other than water), and hot abrasion. An optional heated weight provides a uniform test for evaluating “hot abrasion” resistance of printed cartons, labels etc. Ink Abrasion tester is used in the dry grinding test, wet test, bleaching change test, paper fuzzy test, and special friction test. Effective analysis of the print is poor abrasion resistance, poor adhesion, ink off, ink marking, PS version of the anti-Indian forces and other products, coatings with poor low hardness performance.

The most obvious way to measure the number of twists per unit length of yarn is simply to untwist a known length of the yarn and check visually to see whether the twist has been completely removed. The test instrument that used for to measure the number of twists per unit length of yarn called electronic yarn twist tester . Twist testing methods depends on the specification, accuracy, demanded, from of the sample etc. In general the following points may be followed for getting reliable result. Usually twist is not distributed uniformly along a yarn. Speaking technically, the amount of twist in a materials is inversely proportional to its thickness. This from is ‘twist x weight=constant’’. And for to avoiding having bias in twist measurement, twist should be determined at fixed intervals along the yarn that is 1 yard of distance which is suitable.  Withdrawal of yarn over the end of the package adds twist to a yarn, whereas withdrawal from the side of the package does not. The

Twist has a critical effect on the physical properties of yarn such as softness, tensile strength and cover factor.  Optimum twist level is important for both yarn end-users and production plants.Determining optimum twist can have a critical effect on the physical characteristics of yarns. Yarns with a low twist count are capable or producing a yarn with increased softness for knitting and warmth.Increasing twist count can provide additional tensile strength. However, maximum tensile strength can decrease if the twist angle is greater than the desired amount. The Yarn Twist Tester provides semi-Automatic testing of single or plied yarns. Digital displays of twist for sample length tested, as well as twist per unit selected (twist per inch, twist per centimeter). Automatically stops at end of test. Allows multiple test of same sample. Variable speed. Specify 110 or 220 volts, 50/60 Hz. Electronic Twist Tester meets applicable standards for measuring twist in the yarn.  The
