Yarn Count Testing Machine, automatically calculates count systems used for sliver, roving and yarn, and can also be used for fabric yield. Yarn Count Tester consists of an accurate electronic balance with a capacity of g or g x g and built-in calculating program. Please contact us if you want to know more about yarn count test method. Our new Yarn Meter has a built-in tensioner. This allows the user to add the correct level of tension on their yarn to ensure that the meter works properly. This new unit can also be used to tension yarn in any application. It does not need to be used with the meter (simply remove the meter).

The LH Yarn Friction Meter adds another dimension of versatility to the measurement of yarn friction. In addition to being able to be stand-mounted for quality control functions and laboratory use, it can be hand held to measure yarn under actual operating conditions.
It is direct reading, easy to use, accurate and reasonably priced. Digital Friction Meter KFY The Digital Friction Meter is a reliable economical method of computing yarn coefficient of friction. Windows software has been added which allows the DFM readout to be connected to your personal computer or lap top with a complete statistical package.
Yarn Friction Meter. Lawson Hemphill Yarn Friction Meter, YFM is a small, handheld, portable instrument that measures the coefficient of friction very quickly and accurately. It provides very quick feedback on the effects of wax, paraffin, sizing material on the overall yarn friction values.

Electronic Yarn Count System. Latest Updates • Social. Yarn Friction Tester. Yarn HATRA yarn friction meter book is a recurrent source of difficulties in knitting most products on most machines. Problems may arise from inherently high friction yarns, form variations between batches, from a rogue cone within a batch or from changes that occur in storage.
It is on this principle that HATRA Yarn speed meter and Yarn length meter have been developed. Conclusion 3 Prior to the work of Doyle and Munden, many yarn and machine variables were recognized as having an influence on knitting quality and the dimensions of a fabric in its relaxed state.
However, Munden has shown that a change in any one of. Some common yarn friction meters are illustrated and there is mention of the simple MLT friction monitor which takes up one of two positions, depending on the friction of the yarn passing through it. GI YARN FRICTION TESTER: This machine determines the friction coefficient of yarns during the friction to metal surface.
This machine calculates the frictiction coefficient of yarns by friction angle of °. The speed of the machine is between m/min. The pre-tension is adjusted by pretensioner.

Friction Charging Tester is the antistatic fabric and knitted fabric friction generated by the amount of charged charge test equipment, used to measure the amount of static electricity charge.
+ + [email protected] Various commercial friction testers and test methods (e.g. ASTM D) are available, most of these measuring the tension generated in the yarn as it passes over a cylindrical or flat metal surface, or itself, the yarn-to-metal coefficient of friction (μ) can be estimated by measuring the yarn tension (T 1) prior to the surface and that (T 2.
Friction Testing Apparatus (Indirect)7 (Fig. 2)— Apparatus in which the input tension is measured or controlled to a set value, the output tension is measured, and the coefficient of friction is calculated within or outside the apparatus. Yarn Tension Input Control—A means of controlling the yarn input tension to the nearest 61mN.
Two types of meter may be employed to monitor yarn feed during knitting - yarn length counters and yarn speed meters - which may be considered to be respectively analogous to tachometers and speedometers in cars.
The yarn length counter is simplest in construction, providing a reading of the amount of yarn fed in a certain time period. The data in, can also be used to explain an apparent well-known paradox, i.e. that the friction of a lubricated yarn at high sliding speed is higher than the friction of a non-lubricated yarn.
Thus, we are dealing with two very different phenomena – dry friction, which is independent of speed, and hydrodynamic lubrication, or.
