Working Procedure of Perspiration tester

Perspiration is on everything we touch or comes in contact with our bodies. It can react with certain materials and trigger allergies or shorten product service life. While the mechanics of perspirations tests have been specified since 1947, there is no consensus for an artificial perspiration mixture that will successfully mimic natural human eccrine perspiration.

Perspiration tester determines colorfastness of textiles to human perspiration. The KFG-2041 Perspiration Tester consists of two stainless steel frames. Each frame be loaded with up to 20 samples of 10 x 4 cm between the supplied acrylic separator plates. Loading weights for AATCC TM 15/106/107 and ISO 105 E01/2/4 are included.

Working Procedure :

Thoroughly wet one composite sample in a solution of PH8.0 at the liquor ratio of 20:1 and allow it to remain in this solution at room temperature for 30min. pour off the solution and place the composite sample between two glasses plates measuring about 7.5×6.5cm under a force of about 4.5kg.

Treat the other sample in the same way but with the solution at PH 5.5.

Place the apparatus containing the samples in the oven for 4 hour at 37±2C˚

Separate the sample from the white cloth and dry them apart in air at the temperature not exceeding 60C˚.Assess the change in colour of the specimen and the staining of the white cloth with the greigh scale.

Moisture Management Test Method -AATCC 195

MMT textile moisture management tester Test Method -AATCC 195 is for the measurement, evaluation and classification of liquid moisture management properties of textile fabrics. The test method produces objective measurements of liquid moisture management properties of knitted, woven and nonwoven textile fabrics. The test method produces objective measurements of liquid moisture management properties of knitted, woven, and nonwoven textile fabrics. The results obtained with this test method are based on water resistance, water repellency, and water absorption characteristics of the fabric structure, including the fabric's geometric and internal structure and the wicking characteristics of its fibers and yarns.

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 properties for the range of temperature 130°C to 250°C in one test. A rea
