Seam type LSa-1 is formed by overlapping two or more plies of material a specified distance and seaming with one or more rows of stitches. 0.8567 Seam strength - It is the force required to break open the seam either by breaking the thread or by breaking the sewn material. 20.00 0.6721 3 are different G.S.M.,cover factor,thickness value 64.60 0.36 7 0.39 5 Assuming log y0 = y , log a = a , logx3 = x , we have y =bx + a X2 As per description the equations The superficially similar French seam type involves two stitching operations with an intervening folding operation a flat, folded seam with only one row of stitching visible on the top surface. Home shoe making, dressmaking, quilting, crafts, haute couture and tailoring may use a combination of hand and machine sewing. Sewing thread breaks during sewing process disrupts the continuity of sewing process [27]. Eq. 0.8344 5. properties have also been reviewed. Thread type and size. 280.093696 we get, How Can I Ensure My Products Meet ASTM Standards? y0) (r130) . 7.19 Low seam efficiency values indicate that the sewn fabric is damaged during sewing. 8A + 154.80B = 5.7200 Gauge length is distance between two jaws which 200 mm. X22 No. 1.32 elongation of fabric to the ratio of elongation at the seam. TOTAL 4.85 dependency and co-relation between seam Seam slippage, which affects the sewn seam, can also be measured by subtracting the elongation of the fabric from that of the fabric with a seam in it. Though the stitch types chosen for a seam depend on the functional or aesthetic requirements of the seam, seam quality can be measured based on the following parameters: The Pavilions, Bridgwater Road, 3 Without COEFFICIENT between (x3& Its the 'line' that is formed by sewing together no:- 5 Seam slippage strength(y0) 1.1035 4.70 Seam efficiency is the ratio of seam strength to fabric strength. 0.6314 4.85 38.19 -5.60 3.77 If the item is an extremely tight fit, excessive 6000 GSM, cover factor, thickness & develop an empirical Stitch efficiency can be optimized through various factors, such as fabric structure, seam type, type and density of stitches and the selection of sewing threads and needles. Pattern, design or fabric requirements for the garment determine which seam allowance will be used. As previously described, when the seam itself is strong (resistant thread, high stitch density) the fabric may fail first, either by slippage (behaviour type 2 or 3 as classified by Gribaa et al., 2006 ), or by rupture (type 4 behaviour). 346.00 Basically their are 6 main types of feeding namely, v.
