Investigation of factors affecting the seam slippage of garments

Abstract

Seam slippage often occurs with some garments during the process of wearing or washing, which not only affects the appearance of the garment but also influences garment quality. The purpose of this study is to find out the factors that affect the seam slippage of garments. In order to make the test results closer to those of the garment itself, this study first proposed to make the fabric into a Japanese woman's prototype sample, in order to simulate the garments produced by a garment enterprise. Then, according to standards GB/T 13772.2-2008/ISO 13936-2: 2004 and GB/T 21294-2014, samples were made and seam slippage at the armhole and side seam was tested. Experimental results reveal that the factors that cause the seam slippage of garments are the fabric, seam type and sewing thread. According to the regression analysis, the seam type has a significant effect on the seam slippage of the armhole and side seam, with Pearson correlation coefficients of −0.715 and −0.650, respectively. Thickness, weight, weft density and weave type of the fabric are also important in terms of seam slippage. The weight of the fabric is more significant than other factors; the significant values at the armhole and side seam are 0.009 and 0.002, respectively. In the linear equation, it is shown that weft breaking strength of the fabric only impacts the seam slippage at the side seam. Sewing thread is another important factor for the seam slippage of garments, and its influence on the armhole is obvious; the larger the sewing thread linear density of polyester material is, the smaller the seam slippage is.

The parameters affecting seam quality: a comprehensive review

“…Seam slippage is also dependent on the sewing direction. Seam slippage in the weft direction is higher and with the increase of the angle between the weft yarn and the sewing direction, seam slippage decreases (Pasayev et al, 2012;Ozdemir and Yavuzkasap, 2012;Mukhopadhyay and Midha, 2013;Namiranian et al, 2014;Chen and Cheng, 2019). This probably results from the fact the warp density is higher than the weft density.…”

“…Gurarda (2008) stated that there was no significant effect of ticket number in both the warp and weft direction seam slippage strength of the fabrics. Vice versa, according to the experimental results of Chen and Cheng (2019), the larger the sewing thread linear density of polyester material is, the smaller the seam slippage. Behera and Chand (1997) stated that the seam efficiency of the lightest fabric invariably increases with the increase in the ticket number of the sewing threads irrespective of their composition.…”

“…Seam opening is related to the fabric structure. Malciauskiene et al emphasized that warp density has little influence on the seam slippage and is mainly affected by weft density (Chen and Cheng, 2019). Gurarda (2008) and Pasayev et al (2012) showed that with the increase of the weft density of the fabric, seam slippage decreases.…”

“…Therefore, high puckering occurs in heavyweight fabrics. Behera and Sharma (1998) and Chen and Cheng (2019) stated that resistance of yarn slippage increases with the increase in fabric weight, cover and thickness of the fabric. This may be due to better interloping of sewing thread with fabric and higher contact area due to bulkier mass.…”

Research Progress in the Functional Textiles

“…The unique "skin core" structure of the fiber brought excellent flame retardant performance, and had the moisture absorption, ventilation and comfort of cellulose fiber suitability. [1] Professor Liu of University of science and technology of China synthesized a kind of phosphite modified chitosan (PCS) flame retardant, and deposited the films of PCS and branched polyvinylamine on the polyester cotton blend via layer-by-layer self-assembly technology, so as to prepare polyester fabric with flame retardant property. It was found that the thermal stability of this kind of fabric was enhanced.…”
