Effect of Sewing Parameters on Seam Strength and Seam Efficiency

Abstract

Seam quality is determined by the correlation between types of fabric, structures of fabric, sewing threads and selection of stitches and seams. The performance of seam also depends on the sewing conditions like size of needle, sewing thread tension, stitches per inch and lastly on the proper working and maintenance of the stitching machine. The objective of present study is to investigate and scrutinize the impact of weft knitted fabric structures, sewing thread types and stitch types on seam strength and efficiency of superimposed type of seam for cotton apparels. An experimental design was employed for the study which includes two types of sewing thread and four classes of stitch. The seam strength and efficiency of the fabric were determined by using the tensile testing machine. Seam strength have been measured and analyzed both in course and wales directions. The results revealed that differences existed between the two different thread in relation with seam strength and seam efficiency. Polyester-wrapped threads with a polyester filament core thread shows better seam strength and seam efficiency. This study also assists garment manufacturers to utilize suitable thread type and stitch type to reach quality seams to get to know customers' requirements in terms of seam.

Modeling of technological parameters of filament joints of clothing parts for professional sports fencing

“…The factors that affect the quality of the filament joints are considered in more detail in [13,14] and divided into groups:…”

“…To assess the quality indicators of the filament joints, organoleptic, measuring, registration and calculation methods are usually used [15]. When predicting the quality level of the filament joints by an overwhelming majority of scientists, the influence of one factor or another on the breaking strength and elongation at the time of breaking is studied [12][13][14]. A number of authors in [12,14] found that the strength of joints is affected by:…”

Maximization of Sewing Strength and Minimization of Seam Pucker for Denim Fabrics Using Taguchi Method

“…Seam pucker is an unacceptable waviness in appearance along the seam length [15]. Also the seam performance by means of durability is based on the strength and efficiency of seam as well as seam appearance along the seam line attributed by the seam puckering [20]. Sular et al, compared the seam performance of 12 woven fabrics by means of seam pucker and other seam properties.…”

A model on the viscoelastic behavior of sewn knitted fabrics

“…Therefore, better understanding of the seamed fabric viscoelastic behavior is essential. Previous research studies have investigated some methods to improve the mechanical performance of seams such as changing the stitch density, stitch type, the sewing thread type and fineness, fabric and seam type (Choudhary and Goel, 2013;Phebe Aaron and Chandrasekaran, 2014;Akter and Khan, 2015;Ali et al, 2016;Frydrych and Greszta, 2016;Raj and Devi, 2017;Rajput et al, 2018). However, the literature suffers from a lack of precise models and techniques to predict the time-dependent behavior of the seamed area.…”
