Nylon peel test

Nylon Peel Test Nylon-6 films (10-mil Ihick) were pressed between Teflon-covered stainless steel plates on a 30-ton Carver hydraulic press at 235°C. The nylon film was then cut into 2 x 5 in panels, with care taken to ensure all sides were square. The panels were submerged in a phosphate buffer solution (pH = 7.2, T = 25°C) for 1 h. Excess moisture was removed with lint-free tissue paper. The monomeric tissue adhesive, for example MFC, was applied to one panel, and another panel was placed on top. A 1/2 x 5 in portion of the panels was left unglued. The MFC was allowed to cure for 2 h. Each panel was then sectioned into smaller samples. The xmglued portion was gripped into an MTS MiniBionix (Model 858) and the force required to separate the films at a displacement rate of 2.5 cm/min was measured. The average load after the initial peak was used to calculate the average peel force of the adhesive joint.

On the whole, the peel strength and rubber coverage on the treated Technora fabric samples after peel tests were rdkitively high, and were less dependent on the nylon type.

After the surface layer of the leather sample is peeled off, the sample can be observed under a microscope. The collagen fibres of leather differ in appearance from non-woven fabrics and from the uniform polymers of coating and lamination in the synthetic substitutes. However, some artificial leathers in the market do better than the real leather. It has been reported that some leather substitutes with super-microfibres of nylon, polyester and polypropylene can have similar views of cross-section under the microscope (Cheng, 1998). A combination of the bum test, the chemical test, the infrared spectroscopic analysis and/or the microscopic...
