13-62 Textile Burst Testers

INTRODUCTION

Burst Testers for Textiles are used as a multi-directional tensile test to identify failure in the direction of least resistance for evaluating physical strength and fiber bond. Models are available to test a variety of materials. These models can also be fitted with a device to measure the deflection of the sample prior to burst.

The textile burst tester is designed to meet international standards for tests on textiles. In textiles, the burst tester measures the fabrics strength along with immediate or eventual effects of dyes, chemicals and processes. It also demonstrates the results of wear, age and environment and evaluates the comparative strength of alternative fibers.

OPERATION

The Textile Burst Tester is designed for measuring the bursting strength of fabric materials subjected to an increasing hydrostatic pressure. This pressure is applied to a circular region of the specimen via an elastic diaphragm. The specimen is firmly held round the edge of this circular region by a pneumatic clamping device. When the pressure is applied, the specimen deforms together with the diaphragm. The bursting strength corresponds to the maximum pressure supported by the specimen before failure identical, in the principle to the multi-directional tensile test, Ball Burst Method for Fabrics, this measurement is independent from the cutting direction of the sample (machine or cross) since the failure naturally occurs in the least resistance direction. The rubber diaphragms with specific thickness and shore hardness must have a bulge versus pressure pattern within the tolerance of the standards related to the type of material tested.

APPLICATIONS

Textiles, Fibers, Non-woven’s, Polyester, Fabrics and Felts etc.
Strength, stiffness, dye ability, resilience, fatigue elasticity, orientation and crystallinit

Pressure system:

The hydrostatic pressure is transmitted to the diaphragm by a hydraulic jack associated with a frictionless ball-screw driven by a precision DC motor. The rotational speed and the position of the motor are servo-controlled by means of an optical encoder ensuring a perfect control of the fluid flow rate together with the determination of the displaced volume of fluid.

Sample tightening system:

A large pneumatic jack enables an accurate and reproducible tightening.
The tightening surfaces have an adequate profile to minimize the slippage even for difficult materials like textiles for high volume bags.
The tightening pressure is measured with a precision manometer and may be displayed in metric or imperial units.
The gripping strength is recalculated according to the geometry of the tightening surfaces, and displayed in newtons.

Bursting pressure measurement:

The pressure is measure by a metallic gages pressure transducer (0 to 100 bars)
Accuracy: +/-1% of read value +/-1 digit between 5% and 100% of the FSD.
