The purpose of this review paper is to define the dominating factors (such as fiber, yarn, fabric structure, sewing thread, sewing needle and machine parameters) that affect the seam damages and causing defects. It also describes the various explanations of sewing defects in garment production and critically analyzes them for optimum selection of parameters and speeds for minimizing such faults. Hence, the knowledge of various factors which affect the sewing damages/defects will be helpful for garment manufacturers/researchers to know influence of the parameters and control the quality of producing seam.

This section is not applicable for a review paper.

Sewing damages such as needle cut and other sewing damages/defects are studied mostly in woven fabric. There are very few studies conducted on knitted fabric sewing damages/defects. The sewing damage problems do not have single solution that is capable of removing these damages in fabric. All the determined and affecting parameters related to fiber, yarn, fabric construction, sewing thread and sewing machine must be examined to design appropriate remedial measurement related to machine design, fabric parameters and sewing thread. This could help in minimizing or eliminating the needle cut and other sewing damage problems.

It is an original review work and is helpful for garment manufacturers/researchers to reduce the defects and be able to produce good quality seam.

A hybrid flowshop (HFS) problem on the pre‐sewing o perations and a master production scheduling (MPS) problem of apparel manufacture are solved by a proposed two‐tier scheduling model. The first objective of this paper is to plan a MPS for the factory so that the costs are minimized when the production orders are completed before and after the delivery dates required by the customers. The second objective is to minimize the completion time of the pre‐sewing operations in the cutting department while the production quantities required by the sewing department at several predetermined times can be fulfilled by the cutting department. Experimentation is conducted and the results show the excellent performance of the proposed scheduling model for the apparel industry.

This paper aims to present investigations of the influence of sewing and adhesive bonding technology on the aesthetic, mechanical and conductive properties of the e-textile package. Commercially available conductive textiles are tested for the production of e-textile package by most common cut-and-sewn clothing production technologies.

Sewing, adhesive bonding and seam sealing technologies used to obtain e-textile packages with woven and knitted conductive textiles. Produced e-textile packages described in terms of thickness, bending rigidity and general appearance. Exploitation properties of prepared samples tested by cycle tensile experiment and discussed on the basis of variation of linear electrical resistance property.

Research has shown that a reliable e-textile package can be obtained by applying cut-and-sew technology for conductive tracks of silver coated woven and knitted material. Seam sealing by thermoplastic polymer layer has an impact on the electrical and deformation properties of the samples. To create attractive smart clothing design, the appropriate joining method and its technological parameters must be chosen to ensure the durability and safety of e-textile packages.

The findings of the research are of substantial value for the production of e-textiles by cut-and-sewn technologies. The required shape of the conductive textile element for various applications can be cut and joined to the garment parts using traditional sewing or adhesive bonding techniques.

The purpose of this paper is to comparatively examine the personnel working in the clothing sector by examining them in three different methods in order to determine the working postures, identification of the stress factors of musculoskeletal system and the exposures depending on the working postures. Methods used in the study, REBA (Hignett and McAtamney, 2000), Ovako Working Posture Analyzing System (OWAS) (Karhu et al., 1977) and PLIBEL (Kemmlert, 1995) are the scientific observation-based methods. Within the scope of this study, the working stations and the working postures of the operators who work in the clothing sector were examined and their movements that could cause harm to the body were examined and in conclusion some suggestions were suggested to prevent these movements.

Due to the standard unit of times in clothing sector are short and the work done is very repetitive, 30 min recording was thought as enough for each operator examined. These recorded videos were then divided into 30 s photographs to obtain the poses of the operators’ working postures. In the scope of the research, first, the PLIBEL observation form was filled as the PLIBEL method is more general one. According to the working postures, the body regions which are damaged or can be damaged were identified and the PLIBEL form was filled in the consideration of the risk factors in the form (Malchaire 2011). In addition, the photographs were also analyzed with REBA and OWAS methods for having more quantitative and detailed results.

The working postures of the operators who work in the cutting, sewing, ironing, quality control and packaging departments of six clothing companies were examined in the scope of this research with PLIBEL, REBA and OWAS methods in terms of ergonomy. The results belonging to each department were given separately. REBA and OWAS methods have been applied in order to investigate the working postures in more detail due to the lack of providing numerical data of the PLIBEL method. The reliability of the study has been approved with obtaining the similar results from the REBA and OWAS methods. According to Table VIII, both of the methods show that all the departments in question need ergonomic arrangements. It was analyzed that the cutting department is in the first place which needs ergonomic arrangement immediately (REBA %90.58, OWAS %87.69).

This study is composed of 65 operators who have experience between 5 and 22 years and in the age range of 22–43 working in the cutting, sewing, ironing, quality control and packaging departments in eight different clothing companies. These 65 operators were recorded by video camera during their work. The recording time were selected randomly. The movements of operators during their own work have been taken into consideration.

This paper indicates the usability of the PLIBEL, OWAS and REBA methods in clothing sector. Using these methods in clothing sectors states the value and the originality of this paper.

The designing and initial alignments of 2D garment patterns in 3D space are the key procedures in 3D apparel design. This paper presents a new methodology to prepare and edit initial pattern shape in 3D space by simulating virtual cloth scissoring.

In conventional apparel CAD tools, flat 2D patterns are drawn and sewn in 3D space. Thus, the final appearance of 3D garment cannot be easily predictable for non‐specialized personnel from the flat patterns. This paper adopts the real pattern designing method of “draping”, incorporating it into computer‐based designing so that the user can realistically cut, sew and add the cloth by only using a mouse. 2D and 3D meshes are edited simultaneously and thus a flattening process is not needed.

Several mesh‐based operations such as cutting, sewing, adding, and fixing are devised and have been successfully applied to virtual garment cutting.

Our new pattern drawing method has an advantage that designer can look and feel the garment appearance interactively during the design process. Virtual cutting is identical to the real pattern draping technique and is easy to adopt for designers.

With current computer hardware speed and through using the drape simulation technique, it was possible to drape and cut cloth in real‐time. In addition, both the 3D pattern and 2D flat pattern could be simultaneously acquired.

Evaluates the mechanical properties of 60 different shirting materials: fabric extensibility, formability, shear rigidity, bending rigidity, relaxation shrinkage, and hygral expansion by the adoption of the fabric assurance by simple testing (FAST) system. Investigates manufacturing processes comprising spreading, cutting, sewing, handling, pressing and packaging and correlates the measured properties of the shirting fabric with their actual performance during making up. Claims this overall evaluation of respective fabric performance enables manufacturers to identify the range of mechanical properties ideal for high‐quality shirt production. Adds that specific manufacturing instructions can be prepared, based on the results of fabric property evaluation, for fabrics which tend to present difficulties in production. Points out that these can considerably expedite the manufacture of garments, avoiding the alternative – expensive “trial and error” – solution to problems.

Organizational literatures stress the empowering effects of worker participation programs. The case of a Mexican garment factory is used to examine the contradictory location of women in self-managed teams. While self-managed teams require independent and assertive workers, women workers are hired specifically for their docility. I argue that managers provide the tools and mechanisms for workers to be autonomous decision-makers, while at the same time they gender teams in ways that assure continued female disadvantage. Placed in this contradictory location, women workers both reproduce and resist gender subordination by carving out spaces of independent action, using the language of traditional womanhood.

The purpose of this study is to develop a modular garment assembly line simulator that can be used for various production methods such as traditional mass production or modern small quantity batch production.

For realistic simulation, the actual shape and sewing information of the garment patterns were used. The assembly line consists of process units including the cutter, preprocessor, module assembly, final assembly, finish, and stack units. Any number of units can be arranged and connected to form various layouts. The simulation can be run at an arbitrary speed.

This system can be used to estimate the time required to process the given order for a specific layout. Therefore, it can be utilized as the basis for optimum production line design.

This system is expected to be utilized by garment manufacturers for obtaining the productivity improvement, production cost reduction, and increased competitiveness.

There would appear to be no limit to the future potential for textile applications.

The purpose of this paper is to discuss how brassiere manufacturers develop new designs for bra products, suitable for individual consumers, through consumer codesign.

New product design that relies on conjoint analysis algorithms can depict multidimensional attribute profiles, such that consumers' choice behavior reflects their preferences and overall judgment of the profiles. This statistical technique provides a means to codesign and customize bra products and thereby enhance the overall bra design process.

Bra products codesign suggests goals such as attractive appearance, shoulder strap style, vivid/mild color, elegance/sexy lace, comfort/practicality, fabric, lining, comfort/attractive appearance, neckline design, comfort/excellent function cut, sewn cups, and generous quantities. The most preferred combination of attributes for all respondents is a cotton/cotton blend fabric, seamless bra that offers a detachable shoulder strap, lavender color, a two‐strap style, lace details, and a low‐cut plunge neckline. The paper illustrates consumers' bra awareness attributes, codesign approach, and individual optimum individualized bra designs.

The results provide a useful source of information for product managers, who should consider the use of codesign to design the best products for individual consumers and decrease the risk of design failure, as well as promote consumer loyalty and satisfaction toward the product.

The paper provides a unique method to understand the new product codesign structure and make bra product design decisions that integrate optimum individualized design.
