The current study has been conducted on 100% cotton, polyester/cotton and cotton/lycra single jersey fabrics for investigation of seam performance in term of seam strength and seam efficiency. The influence of various parameters, viz. sewing needle size, sewing needle type and seam angle, on seam performance of these fabrics have been studied and analyzed. The response surface methodology is employed to investigate their effect on seam strength and seam efficiency by analysis of variance and regression equations. The test results reveal that cotton and cotton/lycra fabrics have lower seam strength as compared to polyester/cotton fabric. Also, with increase in seam angle and needle size, seam strength decreases. However, with sewing needle type, an increase in seam strength is observed for all the three fabrics. The cotton/lycra half plated fabric shows higher seam efficiency among all the three fabrics. It is noted that seam efficiency increases with seam angle and sewing needle type. It has been found that SES needle type (Small ball point) exhibits poor seam efficiency but an improvement in efficiency has been observed with SUK (Medium ball point) and SAN needle type (Conical point) for all three knitted fabrics.

基于接缝强度和接缝效率的针织物接缝性能

目前的研究是针对100％棉，聚酯/棉和棉/莱卡单面针织面料进行的，以研究接缝强度和接缝效率方面的接缝性能。各种参数的影响，即。研究并分析了缝针的尺寸，缝针的类型和接缝角度，对这些织物的接缝性能进行了分析。通过方差分析和回归方程分析，采用响应面方法研究了它们对接缝强度和接缝效率的影响。测试结果表明，与聚酯/棉织物相比，棉和棉/莱卡织物的接缝强度较低。而且，随着接缝角度和针头尺寸的增加，接缝强度降低。但是，使用缝衣针类型时，所有三种织物的接缝强度都会增加。在这三种织物中，棉/莱卡半镀层织物的接缝效率更高。注意，接缝效率随接缝角度和缝针类型的增加而增加。已经发现，SES针型（小圆头）显示出差的接缝效率，但是已经观察到对于所有三种针织物，SUK（中型圆头）和SAN针型（圆锥形点）的效率都有改善。
