In this paper, we discussed the particle based mechanical model for numerical simulation of clothing pressure. Human body and clothing were represented as an elastic body by particle system, collision between human body and clothing was represented by impulse force based model. The two simulations were conducted to evaluate the validity of the suggested model. In the first simulation, clothing pressure on the elastic cylinder covered with cloth was predicted to evaluate the precision of static clothing pressure prediction. As a result, it was confirmed that it had the accuracy of 0.08 kPa, but there was a room for improvement to predict on the edge of cloth. Although it is considered that the mesh resolution (particle distance) caused the problem, it is important to decide a suitable mesh resolution for purpose because it is directly with calculation time. In the second simulation, we conducted the simulation that winding elbow with sleeve to evaluate the precision of dynamic clothing pressure prediction. As a result, it was observed that clothing pressure changed with elbow flexion. However it was not able to obtain the accurate result caused by numerical instability in the case of fast elbow flexion. It is considered that time step and collision model between clothing and human body on the simulation caused numerical instability. Improvement and implementation of the simulation considering whole body motion for dynamic clothing pressure prediction are our future work.

In “Cool Japan,” the government has been trying to promote the internationalization of the fashion business by Japanese companies as a national policy since 2005. The aim has mostly failed, and only partially completed efforts have been confirmed. Consequently, the presence of the Japanese fashion business remains weak in the global fashion market. The purpose of this paper is to explain the cause. While the domestic fashion market has experienced rapid growth over the 50 years following World War II, fashion companies have not shown an interest in foreign markets. Designers of ready-to-wear apparel have followed the fashion styles of Paris and Milan. As long as fashion companies were realizing growing revenues, top management of large-scale fashion companies supported these trends. Top management did not delegate significant discretion for designs to the chief of design, and chief or creative directors had uncertain roles.As a result, designers may have lost their creativity in a commercial sense, and the chief of design is no longer responsible for sales. Top management has given more priority to modelisme than stylisme. Much interest was focused on mistakes in the product details rather than customer profiles. Senior management understood that we had efficiently conducted our fashion business in this manner.It became impossible to assume the risk associated with international market expansion. In the 1990s, the price of the property price in Tokyo decreased after collapse of the bubble economy. It attracted the famous fashion houses of Europe to the burgeoning commercial areas of Tokyo. On the other hand, Japanese entrepreneurs were unable to recover markets lost to the Europeans, even by expanding into foreign markets. Despotic leadership is necessary for the success of the fashion business. As for the company form, possession and management should be the same one. The entrepreneur should delegate the necessary discretion to the chief of design. The chief's discretion will depend on the decision premise, which precedes the first stage of fashion design. The design of fashion clothing will be added according to going through the manufacturing process. The virtual “design chain” is determined by the chief of design.The manufacturer of ready-to-wear is to “make to stock.” If nobody buy it, ready-to-wear would not exist, and the values are not found. The defects are caused at the design of the first stage. The cheif should owe its responsibility.This business depends on the sensibility or affection of humans, which is difficult to understand. However, the design chiefs of the textile manufacturers have promoted abduction about the decision premise of the chief designer at Maison. Therefore, marketing activities are being conducted aggressively. The role of a fashion designer of ready-to-wear clothing is different from that of an artist. From a large chaotic space, a “subset” is extracted. Subset is action space that is shared by certain people. It is assumed that a subset of these is represented by several people, model. Therefore, the task of the chief gives silhouette in this model. If we assume that the silhouette is supported by action space, sellable products can be designed. Action space may exist globally across the border. In many cases, global properties for global markets are lurking among these.

Light transmission property of plain woven fabrics was studied in order to perform the fabric design considering the transmission. A light transmission measurement apparatus which could change incidence and receiving direction of light was developed and the change of the transmission factor by light direction was measured for plain woven fabrics. Because structures of the fabrics are anisotropy, the light transmission property showed anisotropy. The anisotropy of transmission factor was remarkable in large incidence angle, and the minimum or maximum values were showed every Pai/4 cycle. An approximation curve of anisotropy was proposed and the anisotropic light transmission factor was estimated from a measurement at front of a fabric and structure of the fabric based on crimp theory of Peirce.

日本のファッション衣料の国際プレゼンスが低い原因は、国境を超えた着用者への製品の提案力の欠如にあった。日本のmodelismeは良好だがstylisme(ことに一次設計)は脆弱だ。スタイルの代替案想起・期待・選択作業は、設計者に対し、グローバルな着用者の行動空間に関する知見を求める。これはまた事業者の決定の価値前提の問題に関係する。大規模なファッション事業者の官僚組織が生み出す「逆機能」とも密接に係る。単にブランドの問題だけではなく、事業規模・裁量・ルーチン・経営資源配分に関わることが判明した。製品展示を半年以上前倒しするテキスタイル設計過程は、衣服デザイナーの決定前提の一部を説明していた。
