Abstract

Purpose

The authors investigate the effects of four basic bodice pattern shapes and developing methods on the appearances of ladies' fitted bodice design. The authors also clarify the preferred appearance among the four ladies' fitted bodice design as reported by Japanese university students and propose a pattern developing method of the preferred bodice design using the four basic bodices.

Design/methodology/approach

Targeting a ladies' fitted bodice design with designated dimensions, four ladies' fitted bodices were manufactured using four types of basic bodice pattern and their development methods: BUNKA from Japan, ESMOD from France, ARMSTRONG from the United States, and ALDRICH from the United Kingdom. The appearances of the four fitted bodices were observed and explained in terms of ease and darts. The authors also conducted a sensory test regarding the preferred shirt appearance adopting a semantical difference method, for 15 female Japanese university students in their twenties. The authors propose a pattern developing method to design the preferred fitted bodice shape using different basic bodices considering the amount and allocation of ease and size and allocation of darts to front and back of the bodice.

Findings

The appearances of the bodices were different even for the same fitted bodice design depending on the type of basic bodice pattern and its developing method. BUNKA had a slightly constricted silhouette at the waist and ESMOD had a straight silhouette and less constriction. ARMSTRONG had the most constricted silhouette and rounded hips and ALDRICH had a slightly constricted curve from the bust to the hips. The shape differences were strongly related to the amount of ease and the difference in waist darts between front and back of the bodice. The Japanese participants preferred fitted bodices that have a constricted silhouette from front and back views. From the side view, a straight line at the front and a constricted shape and emphasized hip at the back silhouette were preferred. By adjusting the allocations of ease and waist darts to front and back of the bodice, it was possible to design the preferred fitted bodice shape even with different basic pattern.

Originality/value

It was found that the basic bodice pattern and developing method affect the final clothing. It is necessary to adjust the allocation of ease and darts to front and back of the bodice to construct clothing using different patternmaking methods. It was shown that it is more important to consider the patternmaking method than to select a suitable basic bodice pattern. It is necessary to understand the characteristics of allocation and amount of ease and the allocation and size of waist darts in both the basic patternmaking method and developing method. This approach is also useful in making an article of clothing with a shape required in other countries.

Abstract

Purpose

The purpose of this paper is to investigate basic block pattern modification according to fabric used and the mismatch between 2D and 3D measure lines at bust, waist and hip girths when ease allowance is changed uniformly.

Design/methodology/approach

For the investigation, virtual try-on software Modaris 3D Fit (CAD Lectra) was used. The straight shape dress fitting was done using seven cotton and cotton blended plain weave fabrics. After virtual try-on, the mismatch d (dbust, dwaist, dhip) between 2D and 3D measure lines was measured in order to determine base pattern adjustments using different fabrics.

Findings

It was found that the position and length of 3D measure lines at bust, waist and hip girths does not match the position and length of corresponding lines in 2D base patterns after virtual try-on due to fabrics deformation, which is related to mechanical properties. It was proved that derived linear equations presenting a relation between mismatch and ease allowance values could be used for basic block pattern modification that 3D and 2D measure lines would coincide during clothing try-on.

Research limitations/implications

This research is limited to cotton/cotton blended woven fabrics and straight dress; therefore, other fabric types and other clothing could be investigated in the future to expand data basis.

Practical implications

The main practical point of the proposed method is that in order to obtain particular 3D ease value in a garment, it can be calculated from 2D ease allowance value and the fabric’s tensile properties using linear equations. The basic block patterns could be modified using this method not only for tested fabrics but also for other fabrics with similar composition, structural and mechanical properties. 3D ease values in garment can be easily checked by using virtual try-on technology without production of real prototypes. The method is applicable for making ready-to-wear or individually tailored clothing.

Originality/value

The proposed method in this paper presented opportunity to modify the basic block patterns of the dress according to the fabric’s tensile properties and 2D ease allowance. The basic block patterns could be modified according to presented linear functions for each tested fabric. The application of this method can fully ensure the interaction between the garment 2D patterns to 3D garment so that a desired 3D garment fitting effect to the body can easily be satisfied by the adjustment of particular fabric characteristics. It offers further possibilities, especially with developing virtual try-on technologies.

Abstract

Purpose

This paper aims to present a flattening method for developing 2D basic patterns from 3D designed garments. The method incorporates the techniques of professional pattern development for the purpose of pattern‐making automation. The aims of the flattening method are to improve the dressing suitability and to produce pleasing figures by reversing design procedures.

Design/methodology/approach

A flattening method is presented in this paper for developing 3D undevelopable NURBS surfaces in 2D. The automatic operation embeds the expertise of pattern makers by reducing total area differences between the designed garments in 3D styles and the two‐dimensional patterns. Basic pattern‐making invokes the boundary constraints which apply mesh alignments techniques.

Findings

The global area difference between the original 3D designs and the 2D‐developed pattern is controlled within 5 percent in order to reach the final outcomes of basic patterns, whose shapes are similar to the drawing patterns currently utilized in the industry.

Research limitations/implications

This study currently handles simple designs, such as basal designs, and can only flatten garments in symmetric styles. The direct flattening method is developed by this study. In addition, this study is supplemented by expert‐based knowledge, and it establishes basic boundary conditions for various garment patterns to increase the feasibility of flattening automation.

Originality/value

This study introduces the fundamental theories and methodologies used in the automatic making of basic patterns from 3D garment designs. It proposes a flattening method with pattern expertise embedded by real‐time approximations of the global area of the 3D undevelopable designs to the 2D patterns.

Abstract

Purpose

This study establishes the principles and process steps of a new basic trousers pattern using measurements obtained according to the rules of the anthropometric measurement system. The newly developed pattern-making system in this study will be called the “Anthropometric Measurements Based Pattern Making System” (AnMePa). It is aimed at producing trousers that are more fitting to the body, thanks to this pattern-making system.

Design/methodology/approach

In this research, four pattern-making systems used in many parts of the world were compared with the “Anthropometric Measurements Based Pattern Making System” (AnMePa) with regard to the overall appearance and body fit of trousers prepared according to these systems. 10 virtual mannequins (VM) with different adult female body measurements were created, and trousers patterns were prepared for these mannequins. The trousers’ patterns were made and dressed on the mannequins in a 3D virtual dressing system. The body fit of the virtual garments was evaluated by five experts. The scores given by the experts were evaluated using the fuzzy logic method.

Findings

According to the results, it is seen that the new basic trousers pattern developed by utilizing the anthropometric measurement system, AnMePa, provides the best body fit among the basic trousers patterns created according to the other examined pattern-making systems. The combination of 3D virtual dressing and fuzzy logic in the evaluation of garment body fit is considered an innovative method for the future of fashion design and production.

Originality/value

In the developed AnMePa, unlike the existing pattern-making systems, values that can be associated with the body measurements of individuals in a way that could be suitable for each community were used instead of constant values in the pattern-making process. Furthermore, the integration of 3D virtual fitting and fuzzy logic in assessing garment fit is considered a pioneering approach with significant implications for the future landscape of fashion design and production.

– The purpose of this paper is to develop an automated custom-pattern-making system using the width-height independent grading method for semi-customized clothing.

Abstract

Purpose

The purpose of this paper is to develop an automated custom-pattern-making system using the width-height independent grading method for semi-customized clothing.

Design/methodology/approach

The system reads basic patterns and graded large patterns and calculates the grading ratio of independent horizontal and vertical values on all points in a pattern. The custom pattern is automatically generated by calculating the horizontal and vertical grading amount according to individual body measurements. The system does not follow any complicated alteration rules.

Findings

The width-height independent grading method can provide custom-pattern fitted primary body circumference and length and helps to quickly produce semi-customized clothing.

Originality/value

There are few studies on automated custom-pattern-making systems without an alteration rule. This study developed an automatic custom-pattern-making system using the width-height independent grading method.

Abstract

Purpose

The purpose of this paper is to produce an upper garment model for three-dimensional (3D) pattern making. This model will take into account ease allowance and silhouette, and will be used to propose a size-changing method.

Design/methodology/approach

The authors used two real garment bodices with a surface suitable for pattern development. The garments were fitted to a designated dummy body and scanned. Using the scanned data, the authors made those upper garment basic models suitable for 3D pattern making. Using one model, the authors produced two bodice patterns, one with the original seam lines and the other with seam lines that differed from the original ones, and then compared them with the original jacket bodice. To construct garment models that were different in size from the basic model, the authors calculated multiplication factors of cross-sectional dimensions (in the front, back and lateral directions) between the basic garment and the actual garment shape worn on a body for each basic model. Using the multiplication factors, the authors made two different size garment models from two different size dummies for each basic model. The authors used these models to make patterns and garments.

Findings

The reproduced jackets had similar shapes, silhouettes and ease allowances to the original jacket. Two garments of different sizes for each original jacket were made using the multiplication factors, and these garments also had similar silhouettes to the original jacket.

Research limitations/implications

The implications of the work could be the new size-changing method.

Originality/value

Using the modeling method, the authors were able to make complex new garment models that take into account ease allowance and silhouette. The ability to size these models up or down using multiplication factors could be a substitute for the grading method.

Abstract

Purpose

Whole garment knitwear is one of the knitwear development trends in the foreseeable future for its advantages of environmental friendliness and wearing comfort. However, the development of new styles of the whole garment knitwear requires both fashion design and computer programming, which makes it time-consuming and difficult. In this paper, a whole garment knitted skirt template Library is introduced to solve this problem.

Design/methodology/approach

The template library composes of silhouette module, design element module and parts shaping technology module. It was built based on a comprehensive investigation of design and technology. By adhering to the principle of similarity and reusability, the template library of whole garment knitted skirts was established through the innovative design and hierarchical classification of compressed patterns and package patterns.

Findings

With the template library, more than 7.7 × 1025 package pattern templates can be generated through the permutation and combination of the package pattern templates of design elements and parts shaping technology.

Originality/value

The results indicated that it can accelerate the design process and improve the design efficiency of new styles with the template library. This approach can also provide inspiration for the designers and realize rapid response and personalized customization of knitted garment production. In addition, the whole garment templates can be applied into constructing other types of clothing template libraries, such as jackets, pants, etc.

Abstract

Purpose

To make individualized men's basic upper garment patterns without sleeves, the authors developed a measuring garment that measures necessary body dimensions and angles all together. Additionally, the authors proposed a method for making individualized basic body block patterns using the obtained dimensions and angles.

Design/methodology/approach

The authors decided on the locations of the dimensions of the body required for making the individualized garments. The authors then sewed multiple stretchable capacitance sensors to corresponding locations on a stretchable T-shirt. To obtain the dimensions with sensors of short length, the authors indirectly obtained each length from the relationship between the actual body length and the capacitance of the sensor. Beforehand, the authors obtained linear-approximation equations for the relationship between actual body dimensions and the capacitance of sensors for five participants and a dummy. The authors then used the measuring garment and the equations to obtain the body dimensions of another six participants. The authors compared the obtained and actual body dimensions to verify the equations. The authors made individualized upper-garment patterns without sleeves and garments for the 11 participants with the obtained dimensions and angles. The authors verified the proposed method in wearing tests comparing garments designed using the proposed method with conventionally designed garments.

Findings

Using the measuring garment, the authors obtained body dimensions close to actual body dimensions. A pattern of the individualized basic upper garment using the obtained dimensions and angles could be drawn. Compared with the conventional patterns, the individualized patterns had notable differences in the locations of the shoulder point and side neck point and directions of the shoulder line, which relate to the shoulder shape (i.e. square, sloping, forward, or backward). In wearing tests, all participants declared that the individualized garment better fitted their shoulders than the conventional garment without tightness around the shoulders, neck, and armpits. The proposed method with the developed measuring garment was thus found to be effective in designing individualized garments.

Originality/value

This paper presents the possibility of not only measuring body dimensions but also designing individualized basic upper garments using the proposed measuring garment. The proposed measuring garment will assist the efficient manufacture of individualized upper garments without a three-dimensional scanner or special skills.

Abstract

Purpose

With the intention of detecting and describing a series of team learning patterns within a selection of organisations, an extensive exploratory and qualitative research project was conducted in seven phases. The study at hand aims to report on the most recent phase, namely eight case studies in the public employment service of Flanders (Belgium) and aims to expand the provisional typology of learning patterns and to explore the strategic relevance of these learning patterns in the light of a strategic human resource development (HRD) policy.

Design/methodology/approach

A qualitative research approach with a multiple case study design served as the methodological base. A total of 22 interviews in eight cases were conducted in the competence centres of the Flemish employment service, what brings the total to 40 cases and 150 interviews.

Findings

Hitherto, five basic learning patterns and 16 variations make up the provisional typology of learning patterns. The strategic relevance of the learning patterns varies with respect to the scope of the developed competences and the degree of orientation to future of the organisation and the career expectations of the employees.

Originality/value

The provisional typology of learning patterns has proven to be useful as a tool for the identification of configurations of workplace learning in teams. The exploration of the strategic relevance provides clues for the alignment of the HRD with the organisational strategy.

Abstract

A comprehensive apparel CAD system was developed to perform automatic garment pattern drafting and the prediction of the final drape shape of designed garment putting on the human body. Three dimensional apparel CAD system starts with a flat garment pattern drafting system. A computerized pattern design script language has been created based on the traditional patterner’s principles to develop an automatic draft system of performing basic garment pattern drafting as well as grading rule generation. A pattern modification system was also developed considering functions required in apparel CAD such as auxiliary pattern generation, seam line creation, and dart manipulation to generate engineering patterns which can be used in the three dimensional garment shape prediction system presented later in part II of this paper.
