The objective of the study is to find out the impact of the yarn count ,stitch length , stitch density, fabric thickness, loop shape factor, tightness factor ,GSM and porosity on the bursting strength of the single jersey weft knitted fabric. The experimental results have been statistically evaluated with Analysis ofVariance (ANOVA) test , Results show thatstitch length , stitch density, fabric thickness, loop shape factor, tightness factor ,GSM and porosity areeffective on bursting strength and individual ANOVA test results show that stitch density , fabric thickness , tightness factor , GSM and porosity are Individually effective on bursting strength .the GSM parameter of the fabric is fundamental for bursting strength , the correlation relation and R square values of GSM with bursting strength found to be in order 0.839& 0.9438.

For getting high performance knitted goods has been expanded by changing the raw materials , loop length ,course & wales ,GSM machine gauge &designs etc.The performance of the fabric depends on the bursting strength , tensile strength ,tearing strength , air permeability etc.Çoruh [1] studied changes in the mechanical properties of weft knits as a function of the structure and density and relationships between the hand, knit structure and density. the quality of fabric production was maintained according to specific constraints and objectives without producing the comfort properties desired. Statistical analysis indicates that are significant for the air permeability, bursting strength and water vapour permeability of the fabrics.El-Tarfawy [2] investigated the failure behaviourof different samples withdifferent percentage of polyester/ lycra single jersey knitted fabric. Tensile and bursting strength were measured , adding Lycra loaded the loop with un-balance forces and unevendistribution of stresses in the wale and course directions. Tensile, bursting strength and Young’s modulus gave highcoefficient of correlation with lycra percentage.Uyanik [3] studied the bursting strength properties of the knitted fabrics on the basis of splice types. The obtained yarns by splicing in different splicer in the knitted fabric, the tests of structural properties and bursting strength were applied for the fabric samples. The results unexpectedly indicate that splice types do not have effect on the bursting strength of the knitted fabrics in spite of the results showing splice types clearly affect yarn strength. But, fiber types are effective on the bursting strength as expected. Besides, fabric structural properties do not have effect on the bursting strength because of constant knitting parameters.Sitotaw [4]investigated the dependency of bursting strengths on knit structures.Badr et al. [5]studied four different blends of cotton and Modal yarns (100% cotton, 50/50% Cotton / Modal, 70/30% Modal / Cotton and 100% Modal) were produced on the same knitting machine with different yarn input tension ranging from 2 CN to 14 CN. All the produced fabrics were half bleached and dyed under identical dyeing conditions and two different finishing methods. The dimensional properties, physical properties, some mechanical properties and shrinkage weremeasured for the produced fabrics.Khanamet al. [6] investigated the relationship between bursting strength, pilling, extension, and residual extension with GSM. Furthermore, from grey to dyed stage, a visible change in GSM occurred and the influence of GSM in different physical properties also appeared significantly. A strong relationship of bursting strength, extension, and residual extension with GSM change of 100% cotton single jersey fabric was found.With the change of fabric condition, i.e., grey and dyed stage fabric, the physical properties shows significant changes in terms of characteristics Bursting strength, extension, and residual extension was decreased from grey to dyed stage. Kan [7] studied the effect of bursting strength of knitted fabrics in relation to ultraviolet protection. Differentknitting
