Fabric bursting strength tester can perform textile, industrial fabrics, knitted fabrics, woven fabrics, coated fabric bursting strength test.

Bursting strength directly reflects the durability index of the fabric when it is deformed and ruptured by external force. According to the wearing or use of the fabric, the bursting strength is one of its important assessment indicators. If the bursting strength is unqualified, no matter how good other performances are, it can only be downgraded or discarded at present.

Factors that are affecting the test result of fabric bursting strength
A.Internal factors
1)Yarn breaking strength and elongation of the impact. When the yarn in the fabric has high breaking strength and large elongation, the bursting strength of the fabric is high.
2)The thickness of the fabric is influenced by other same conditions, which is when the fabric is thick and with strong bursting.
3)Warp or weft density of the fabric. When under other same conditions, the fabric density is different. The top of the fabric will crack along the density of small tear, the gap was linear, and the fabric bursting strength is low. The hooking strength of yarn. In the knitted fabric, the hook strength of the yarn is large, and the bursting strength of the fabric is high.
4)The fineness and the density of the yarn in the knitted fabric also influence the breaking strength of the knitted fabric. Improve yarn density and coil density, bursting strength also increased.
5)The effects of fabric bleaching, grinding, dyeing, enzyme washing, resin qualitative finishing and other treatment. Under the influence of these different processes, the bursting strength of the fabric decreased. When using different processes and materials, the breaking strength is not the same degree of decline. In general, the bursting strength of the darker color fabric is lower than the light color.

B.External factor
1) The impact of adopting the test method
Using different test methods, the test range is not the same, and the test results will be biased. The current testing methods for fabrics include hydraulic method, air pressure method and steel ball method.
2) The impact of the test environment
In the burst strength test, the test environment also has a great influence on the burst strength of the fabric, so the tester needs to strictly follow the standard to select the corresponding test environment.
3) The influence of the operator
Effects of tester readings. Relative to the hydraulic top breaking strength machine, because different people's eyes are not consistent, or there is no positive reading in the counter, the reading will also have deviation. The operator did not test according to the operation procedure and some mistakes occurred during operation.

Three Test Methods for Burst Strength of Fabrics
A. Ball Burst test method
Ball Burst Strength test principle: a particular area of the sample clamped in the fixed base of the ring specimen. The spherically shaped mandrel is perpendicular to the sample at a constant moving speed, deforming the specimen until it breaks, and measuring the breaking strength.

B. Hydraulic bursting test method
Bursting Strength Tester is applied to determine the bursting strength test and distension at burst of woven, knitted and non woven fabrics,papers and boards by the application of hydraulic load under a rubber diaphragm.



C. Pneumatic Bursting test method
Pneumatic Bursting strength Tester is used for determining the bursting strength of woven or knitted fabrics, non-wOven, paper, leather and board byapplication of a pneumatic load under a rubber diaphragm of a specific area. Provide with a digital readout of pressure with peak value holdfacility, renewable rubber diaphragms, and manual clamping device with acrylic bell, fonward reverse and neutral drive system.Provideaccurate elongation information of fabrics, up to 0.1mm.
