Abrasion Tester For Sole Leather

a.Compressor with 1/2 H. P. motor
b. Vaccum pump for removing abraded particles
The resistance to abrasion of sole leather may be determined with the help of a drum type abrader (similar to NBS Abrader). In this test, an abrasive cloth strip of a specified grit is fixed over the circumference of a drum, which is rotated at a specified speed. The test specimen, in shape of a rectangular strip, is held on a metallic bar located above the drum such that its longer axis is perpendicular to the axis of the drum. When the metallic bar is pressed against the drum, the test specimen gets abraded. The number of revolutions needed to produce a depth of abrasion of 2.5 mm is determined and compared against that needed to produce a depth of abrasion of 2.5 mm in a standard rubber compound to obtain the abrasive index of the leather sample under test.

Finish Film Adhesion Tester

The strength of adhesion between finish film and the leather surface it is applied on may be found either by pressing a pressure sensitive adhesive tape over it and peeling it off, or by separating the finish film from leather and finding the force needed to separate it further. The first method is empirical in nature and cannot be reproduced accurately as the adhesion strength of various adhesive tapes and their bonding with the finish surface cannot be standardized. Hence the second method Is generally used for this determination. In this method, a smooth metallic specimen mounting strip is pasted onto the finish film at right angle to the axis of the test specimen with the help of a suitable adhesive. After the bond is set, the excess adhesive is cleared off and the mounting strip held in a vertical frame. The end of the test specimen is separating from the finish film and a pan containing dead weights suspended from it. The force needed to cause the finish film layer to separate further is determined by adding dead weights on the pan till the separation of the film from the leather takes place.

The ability of light leathers and leather-cloth used in manufacture of shoe uppers, gloves, and garments to withstand repeated flexing without cracking is determined with the help of a flexing endurance test. In this test, test specimens in shape of rectangular pieces are folded and clamped at each end to maintain them in a folded position in a set of grips, one of which is fixed while the other is able to oscillate. The movement of the oscillating grip causes the fold in the test specimen to run along its centre. This operation is carried out repeatedly and the test specimens inspected periodically to assess the damage produced. The equipment used for this test is called as Flexometer.

Water Vapor Absorption Tester

Specimen Cutting Die
The weight of water vapours absorbed by a sample of leather is determined by fixing a circular piece of leather over a cylindrical cavity in a metal container having distilled water inside it. The test specimen is held firmly against the lip of the cavity and allowed to come in contact with the vapours left off by the water for a specified period of time. The gain in weight of the test specimen because of absorption of vapours by it is determined, from which the value of water vapour absorption is calculated.

Water Vapor Permeability Tester

Specimen Cutting Die



In the dynamic waterproofness test of sole leather, the leather test specimen is wetted on one surface and is flexed and compressed in the same manner as the sole of a shoe during walking. The penetration time, water absorption, and water transmission are determined to evaluate the water resistance of the leather sample under test. Permeometer for sole leather consists of a fixed platform with its upper surface covered by a strip of cotton gauge kept moist by a slow flow of distilled water from holes in the platform. A brass roller is provided to move in a horizontal direction along the length of the platform with the help of a motor, gearbox, and link mechanism. The roller is mounted on ball bearings with its axis horizontal and perpendicular to the direction of movement of the roller.

Rub Proofness Tester

The rub proofness tester is used for determination of fastness of colour of light leathers to wet and dry rubbing and for measuring the transfer of colour to the material with which it is rubbed. The test specimen is rubbed with a rotating circular felt pad pressing against it under a specified force, and the number of revolutions of the pad required to produce certain specified effects is determined. This equipment can also be used for assessing the degree of damage to a material during mild wet abrasion imitating the scuffing action of a damp hose on footwear insole during wear. A rotating wet circular felt pad, covered with a worsted fabric under a specified contact force rubs against the test specimen. Overall damage to the test specimen is assessed by measuring its mass loss after a specified numbers of rubs.

The uppers of shoes get folded over the toe portion every time a step is taken. These repeated foldings cause the finished grains to start cracking, resulting in loss of water resistance. To ensure that the leather uppers retain their water resistance for a reasonable period of use, the action of such foldings on them is evaluated by subjecting test specimens taken from the leather to a water penetration test using a penetrometer. In this apparatus the test specimens are held in form of a trough between two cylindrical grips. One of the grips is then repeatedly moved towards and away from the other along their common axis. The test specimens are kept immersed in a water bath up to a part of their periphery. Penetration is detected when an electric conductivity is established between the inside and outside surfaces of the test specimens. The time needed to cause penetration of water through the test specimens is determined and taken as an index of water resistance of the leather. The test can be further continued to determine the percent gain of weight of the specimen due to water absorption and also to determine the mass of water that is transmitted.

Heat Resistance Tester

The resistance of the surface finish and colour of leather to action of heating such as may occur when shoes are flamed, hot blasted, ironed, or subjected to other shoe making operations involving contact with hot tools, machine parts, air and gases, is determined by pressing a piece of finished leather under a copper bit maintained at different elevated temperatures for a period of five seconds under a specified load and evaluating the change in colour produced with the help standard grey scale for change in colour.
