Preparation for the IULTCS Leather Friction Tester test

Preparation for the IULTCS Leather Friction Tester test: 

The IULTCS Leather Friction Tester is suitable for testing the abrasion resistance of products such as plastics, automotive parts

Testing principle.
Friction head (with or without additional weights) on the square wool felt on the friction platform of the leather (stretched or not stretched) for reciprocal friction, a certain number of times after the wool felt for color staining gray card comparison, the test leather for color loss gray card comparison, evaluation of the grade.
 
Preparation before the test.
 
Test before the instrument needs to be connected to the power supply, the exhaust port connected to the vacuum cleaner.
 
Accessories and other instruments: a pair of standard grinding wheels, double-sided adhesive (hard), fine sandpaper (for calibration). According to the requirements of different standards also need to prepare 0.1mg precision balance, fabric strength machine, appearance evaluation light box, etc., to evaluate the test results.

The Leather Friction Color Fastness Tester

Leather friction color fastness tester applied to test leather property in shoes, clothing, luggage handbag industry, research laboratories; commodity inspection, arbitration and technical supervision departments.Leather friction color fastness tester test the degree of decolorization of dyeing leather after friction. It can used to test the leather color resistance to dry, wet and friction. This instrument is suitable for leather, textile, belt, trademarks, cardboard and other friction materials by foreign object damage and decoloring. The machine is designed to carry out a rub fastness test on the surface of leather or coated fabrics to determine the marring of the surface finish and to assess the amount of color transfer from the sample to the rubbing pad. This machine is designed to determining the colorfastness of leather, plastics and textile materials. The colorfastness is assessed by checking change in color of the specimen and stain of the felt after rubbing the ...

How Sublimation Fastness Tester Works?

Sublimation Fastness Tester is a suitable instrument for dyestuff manufacturers as well as textile processors for checking effects of dry heat on dyestuff. Qinsun-lab offers Sublimation Fastness Tester of the best quality and at the best price which gives accurate results.    Features of Sublimation Fastness Tester : Testing the effect of direct heat on the dyestuff； up to 250°C temperature range； Independent digital timers with the minimum display of 1℃(one with each of top and bottom plates, respectively)； Can test entire range of temperature in a single test.                           Working Principle: A dyed cloth piece is sandwiched between two undyed pieces and placed to cover the heat pads and the test goes on for a preset time period. The fabric pieces should be picked up immediately. The undyed fabric pieces will be stained by the dyes. This gives the sublimation fastness ...

what is the Working Principle of fogging tester?

Fogging Test Chamber   is the best tool to determine the fogging characteristics of automotive or other vehicle interior materials. The fogging tester is applicable for gravimetric method, photometric method and haze measurement method. Working Principle: The main frame of the Fogging tester includes a water sink fully filled with specified ethylene glycol, which can reach a high temperature. At the time of testing, leather specimens are put in the six standard glass containers filled with  high temperature liquid, and the stainless steel containers are placed above each glass. Relying on the constant water flow distribution, the temperature can maintain at 20℃ constantly, and it can be adjusted through the regulation device connected to the main frame. This controlled environment condition will generate a layer of “fog” on the surface of specimens. The operator can determine the fogging characteristics of materials based on gravimetric analysis method or refraction...
