Terminology 3.1 Definitions: 3.1.1 bursting strength, n—the distending force, which isThe HydroBurst Burst Strength Tester utilizes hydraulic bursting (diaphragm method) to determine the burst strength and expansion of knitted fabric, woven fabric, non-woven fabric, laminated fabric, elastic woven fabric, paper, and other materials when subjected to stress in both warp and weft directions, as well as in all other directions, to get the material’s burst . This paper investigates the bursting strength performance of single jersey weft knitted fabrics. The objective of the study is to find out the impact of the yarn count ,stitch length , stitch . 10 The type of knit structure has an effect on extensibility and strength of knitted fabrics. 11 The knitting parameters particularly yarn feeding load has an effect on fabric on fabric relaxation .
In the burst strength test, the test environment also has a great influence on the BS test results, so the tester needs to choose the corresponding test environment in strict accordance with the standard. 3. Measures to be Taken to Ensure the Accuracy of the Test Results. There are many factors affecting the results of the fabric burst strength .Bursting strength is a method of measuring strength in which the fabric is stressed in all the directions at the same time and is therefore more suitable for materials such as knitted fabrics. During a test a fabric fails across the direction which has the lowest breaking extension. Tensile test is unidirectional and thus suitable for woven .The bursting strength properties of knitted fabrics are related to the raw material, pattern type, elastomer ratio, and yarn count. . measured by bursting strength testing methods (Au 2011).
5.2 In cases where test results obtained using the procedures in Test Method D3786 have not been correlated with actual performance, Test Method D3786 is considered satisfactory for acceptance testing of commercial shipments of textile fabrics for bursting strength since the method has been used extensively in the trade for acceptance testing. In .This document describes a pneumatic pressure method for the determination of bursting strength and bursting distension of textile fabrics. NOTE ISO 13938-1 describes a method using hydraulic pressure.

5.2 In cases where test results obtained using the procedures in Test Method D3786 have not been correlated with actual performance, Test Method D3786 is considered satisfactory for acceptance testing of commercial shipments of textile fabrics for bursting strength since the method has been used extensively in the trade for acceptance testing. In .Key words: knitted fabrics, bursting strength, experimental design, Taguchi design. Taguchi views the design of a product or . The fabric bursting strength was tested 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 .IS 1966 (Part 1): 2009 ISO 13938-1 :1999 6.1.2 Bursting pressure shall be indicated with an accuracy of ±2 % of full scale range above the first 20 % of range. 6.1.3 Height at burst up to 70 mm shall be indicated with an accuracy of ±1 mm. Zero position of the measuring gauge shall be adjustable to accommodate the thickness of the test specimen.
In case of knitted fabrics, testing and analysis are equally important to assure the quality production both during as well as postproduction. It helps to observe the faults of machinery as well as of materials throughout the process of production. . In knitted fabrics, the bursting strength tester, shown in Fig. 19.12, determines the results .The bursting strength test is an alternative method of measuring strength and elasticity in which the material is stressed in all directions at the same time and is therefore more suitable for such a material. . Hussain, Safdar, Nazir & Iqbal. (2013).‘Optimizing the Shrinkage and Bursting Strength of Knitted Fabrics after Resin Finishing .
The pressure is increased smoothly until the test specimen bursts. The bursting strength and bursting distension are determined. 5 Sampling . For most fabrics, particularly knitted fabrics, the test area of 50 cm2 is applicable.
