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 ...

Features Of The Smoke Toxicity Chamber

The Smoke Density Chamber is widely used in all industrial sectors for the determination of smoke generated by solid materials and assemblies mounted in the vertical orientation within a closed chamber.Building smoke density tester, plastic smoke density tester is with built-in burning lamp, and by the smoke box into a 45 ° angle, for the determination of building materials, solid materials and related products combustion static tobacco production. It measures the specific optical density of smoke generated by materials when an essentially flat specimen, up to 25 mm thick, is exposed to a radiant heat source of 25 kW/m , in a closed chamber, with or without the use of a pilot flame. The radiant heat source can be easily replaced with the Conical Radiant Furnace for testing of specimens in the horizontal orientation according to ISO 5659 and IMO FTP Part 2 requirements. Features Test chamber with full width opening door, allowing easy access for sample loading and chamber clea...

Feature Of The Thermal Radiation Droplet Tester

Thermal Radiation Droplet Tester can be used for more than 5mm thickness of rigid and elastic material performance evaluation, and it is developed according to flame test standard NF P92-501. The tester to provide 30KW / m2 heat radiation, which may lead to volatile flammable gas sample and triggered the combustion of volatile gases, and at the same time to observe the state of the flame spread through the material and estimate combustion heat release data. Suitable for railway vehicle test radiation test methods of fire resistance materialIt is used to determine the resistance to the thermal radiation through up a radiant heat source placed on the top of the sample to generate gas combustion, droplet, fiber combustion, etc. thus the fire safety of automotive interior materials is determined. Automotive interior materials droplet characteristic tester is according to appendix 7 of ECE R118 to determine the melting characteristics of materials. With mechanical and electrical e...

Washer And Dryer For AATCC Shrinkage Testing

The   Washer And Dryer  through either the family type washed many times to the textile afterwards measures the textile the shrinkage or the elongation ratio, after also might carry on each kind to wash the outward appearance evaluation. Meet to AATCC standard testing method (88B+C, 124, 130, 135, 142, 143, 150, 172 and 179). The machine consists of washing machine and dryer. It is a shrinkage tester appointedby AATCC. After one or more washing, it will test shrinkage or elongation of textiles, and rate the samples to make the care label.The shrinkage rate is the percentage of fabric shrinkage after washing or immersion. When we wash something in the daily life, such as viscose fiber, rayon, rayon, woolen fabric,woolen fabric, linen fabric, silk fabric, synthetic fiber and blended fabric. Their drying process will appear different shrinking performance degrees. Washing temperature,washing time, washing dynamics, detergent type and detergent dosage will effect fa...

The Shoe Slip Resistance Testing Machine

The Shoe Slip Resistance Testing Machine is equipped with a special design of the control and data acquisition system, to provide users with the friction coefficient of each specimen.To obtain this result by closely controlling the various forces involved in the test, these forces include the speed of movement provided by the variable speed motor. The shoe and heel materials slip resistance tester has been developed following extensive biomechanical studies and is representative of conditions encountered during walking when slip is most likely to occur. A normal walking step commences with heel strike and ends as the toe is lifted from the ground. Slip is most likely to occur shortly after heel strike and just before toe lift when half body weight is being applied. The  shoes slip resistance testing equipment measures the slip resistance between the sole of the shoe/boot and the floor.  Other surfaces can be used with the machine and are available to order. Providi...

How The spray rating tester Works

The spray rating tester comprises a metal framework allowing distilled water to be sprayed through a nozzle onto a test specimen at 45° and 150mm below the nozzle. The appearance of the specimen is compared against an standard photographic scale.A certain volume of distilled water is sprayed into the center of the fixed sample. Before testing is carried out the specimen shall be conditioned for at least 24hours in the standard atmosphere. Water sprayed against the taut surface of a test specimen under controlled conditions produces a wetted pattern whose size depends on the relative repellency of the fabric. -To carry out the test, first of all fasten the test specimens securely in the metal hoop of the water repellency tester so that it represents a smooth wrinkle free surface and place it face up on the tester. -Adjust the metal hoop so that the centre of the spray coincides with the centre of the metal hoop. Later pour 250 ml of distilled water at normal temperature...

Test Principle of Moisture Management Tester

To measure the dynamic liquid transport properties, a sample is placed horizontally in the instrument between the upper and lower sensors.  These sensors are made of concentric rings of pins.  A solution, representing perspiration, is dropped on the center of the upper facing (skin side) of the test sample.  As the solution moves through and across the sample, the changes in electrical resistance are measured and recorded. The MMT- Moisture Management Tester  is the instrument on the market that can precisely measure the liquid management properties of performance and technical fabrics, ensuring the comfort and protection that consumers demand.Fabric liquid moisture transport properties in multi-dimensions, called moisture management properties, influence the human perception of moisture sensations significantly. To improve the comfort of today's clothing, especially in sportswear, it is important to know the liquid moisture management properties of the fabric...

Definition of Scratch And Mar

For grained surfaces such as pp/talc in automotive applications we use the Erichson multi-finger scratch and mar tester that generates a pattern of crossed lines on test plate. Thereby, the scratching force as well as the diameter of the scratching head can be adjsuted. The difference in color before and after the scratching is measured (D L) and taken as indicator for the scratch resistance. Secondly, we use the five finger scratcher to evaluate the scratch resistance of grained surfaces.  It is a fast method to evaluate the scratch resistance at different forces in one single test.Scratch and mar are types of mechanical surface damage that can occur during normal usage and handling, shipping or assembly procedures.  Defined as "the resistance of a solid body to penetration by an edge or protuberance on a second body that is moving along its surface", scratches are usually associated with a single occurrence in the specimen surface.  Normal scratching includes defo...
