The purpose of this study was to research the characteristics of the pattern design and the weave construction of 67 fashion fabrics in women's Hanbok. All the fabrics were made by 100% silk. Arrangement, size, and the type of patterns were investigated for research of the pattern characteristics. Pattern weave and background weave were analyzed, then the weight and the thickness were measured for studying the fabric construction. The results were as follows. First, irregular arrangement was more commonly used than regular arrangement, and then the complex arrangement and the combination arrangement were appeared considerably because of the existence of the various patterns in a fabric. Third, the types of pattern weave construction were much more than those of background weave construction. This is caused by the expression of dimensional effect for patterns. This survey can be practically used for development of pattern design for Hanbok industry and furthermore it will contribute to revitalizing of Hanbok market to overcome design limit in the future.

Welding is a significant part of the construction industry. Since most high-rise building construction structures rely on a robust metal frame welded together, welding defect can damage welded structures and is critical to safety and quality. Despite its importance and heavy usage in construction, the labor shortage of welders has been a continuous challenge to the construction industry. To deal with the labor shortage, the ultimate goal of this study is to design and develop an automated robotic welding system composed of a welding machine, unmanned ground vehicle (UGV), robotic arm, and visual sensors. This paper proposes and focuses on automated weaving using the robotic arm. For automated welding operation, a microcontroller is used to control the switch and is added to a welding torch by physically modifying the hardware. Varying weave patterns are mathematically programmed. The automated weaving is tested using a brush pen and a ballpoint pen to clearly see the patterns and detect any changes in vertical forces by the arm during weaving. The results show that the weave patterns have sufficiently high consistency and precision to be used in the actual welding. Lastly, actual welding was performed, and the results are presented.

We selected four kinds of cotton velvet and chafed before and after cleaning, then in accordance with abrasion times we measured of pile exclusion rate and examined the relationship of the pile exclusion rate, its thickness and the air permeability. An experimental study was carried out the pile weave construction, the density, the yarn to yarn, the shrinkage, and the pile substantiality. The results were as follows: 1. In accordance with increments of shrinkage phenomenon of pile fabric for cleaning process, pile exclusion rate was decreased. 2. The ground weave of pile fabric and the yarn to yarn of warp and weft direction were affected by the pile exclusion. 3. It is linear of pile substantiality of pile fabric and pile fastness. 4. In estimation of pile exclusion rate, it is proper to make use of air permeability and measuring value of thickness.

There are many CAD commercial systems such as fabric design CAD for fabric designers and pattern design CAD including visual wearing system for garment designers. But there is no fabric design system for weaving factory, so the data base system related to the fabric design for weaving factory is needed. Therefore, in this study, as a preliminary study of the data base system for fabric design, easy decision of warp and weft densities according to the various yarn count, weave constructions and materials were surveyed through analysis of design plan for nylon and polyester fabrics from wearing factories.

Recently, CFRP composite is more and more used in the various fields because of a higher specific modulus, chemical property and so on. Most products using CFRP composite are manufactured by construction of components. Various components are joined with those by bolts and pins. Holes for bolts and pins decrease strength and fatigue life of components, because those act as notch in structures. In this paper, we experimentally evaluated the fatigue life of hole-notched and unnotched weave CFRP plate. Then, we compared the two results and proposed an equation for prediction of fatigue life.

Hand characteristics related with structural properties of fabrics have something to do with mechanical properties of fabric. In this study, the mechanical properties and hand characteristics have been analyzed according to fabric structural parameters such as the weave structure and the linear density of weft of cotton fabric. Mechanical properties have been used by KES-FB system which measures hand characteristics and mechanical properties of fabric. Linear density of weft, tensile, bending, and shear properties are decreasing with increasing weft linear density, and there is no considerable effects on compression and surface properties. In case of formability with weft linear density, B/W, 2HG/G, 2HB/B, 2HB/W, $\sqrt[3]{B/W}$, $\sqrt{2HB/W}$, W/T except MMD/SMD, WC/T, and WC/W have been effected. There is a high correlation between the crimp, tightness, hand, formability and mechanical properties specially tensile linearity, bending, shear, and compression properties. The weft crimp influences the bending rigidity, shear properties, and the tightness which have effects on the tensile linearity, bending, shear, compression properties, hand, and formability.

The purpose of this study was to develop and evaluate working clothes for shipbuilding workers who work in one of the poorest work environments among national strategic industries that are playing pivotal roles for the Korean economy. For the study method, requirements collected through interviews and field surveys were incorporated to directly weave the fabrics for working clothes. The colors were then selected and the woven fabrics were dyed with the selected colors. Using these, the designs of working clothes were planned from the construction and design aspects and four winter clothes and four spring and fall clothes were produced. Afterwards, the workers dressed in these clothes and workers and managers evaluated them in terms of appearance, color satisfaction, design satisfaction, and safety mind harmony on a five point scale. This study found that the new working clothes offered better functionality, design, and safety compared to existing working clothes.

In this study, the laminating of TPU film after coating of primer adhesive on the fabrics was applied in order to secure the strength to withstand a fall from a higher altitude by increasing the adhesion between the fabric and the film layer. It seems that the fineness of the yarn and the weave construction have a greater effect than the type of the laminating films. The order of superiority of the laminated fabrics by film type and thickness was the same for 1000 denier and 210 denier fabrics, and the tendency was consistent with the order of superiority in the film properties and peel strength tests. The tear strength of laminating fabrics increased three to four times for 1000 denier fabrics compared to the fabric alone, but it decreased by 2 times for the 210 denier fabrics. Summarizing the above results, it is most appropriate to combine 1000d fabric with three types of laminating films(100~200㎛ thickness) of A(0.2T) or B(0.15T) or D(0.1T) considering the air pressure resistance, the impact resistance during the fall, and the durability against damage during use.

The purpose of this study is to document an unidentified velvet fabric which is located in the Museum. The investigation was conducted by analyzing color, weaving technique. pattern of the study object. To identify the origin of the object, many references about color trends, construction methods and patterns were accessed. Two comparative objects which were dating from 1600 to 1699 in the Museum of F.I.T. were selected since they are similar to the study object. The results of this study can be summarized as follows; (1) The type of this study object is 'cut and voided velvet'. It is obtained establishing the motif as areas of cut pile so as to form a pattern, while leaving other areas of the grounded weave without pile. Two flowers and two tulips with S curved stems are composed as one unit in the vertical direction. (2) The colors used in this study object. which are ivory, smoke blue, medium orange, and yellow. are part of a new trend color in the $17^{th}$ century. (3) The vertical undulating stripe patterns are also of significance in this fabric. They seemed to be contemporary with the serpentine line which was common since the $15^{th}$ century and the vertical stripes pattern which appeared from the $16^{th}$ century. (4) The stylized tulip patterns of this study object began to appear in the early $17^{th}$ century. The stems and leaves of this patterns are less sinuous than the floral motifs of the later $17^{th}$ century. Therefore, the study object is dated to early in $17^{th}$ century because of the color combination. stripes. stylized tulips, leaves. and stems are showing the characteristics of this period.
