Two protease-like proteins, KrtA and KrtC, were identified in Fusarium oxysporum 26-1. Genes coding these proteins, krtA and krtC, were isolated and characterized. Recombinant KrtA (rKrtA) and KrtC (rKrtC) were successfully expressed in Aspergillus oryzae and secreted. The combination of rKrtA and rKrtC completely removed the cuticle of wool fibers. © 2013 The Society for Biotechnology, Japan.

Stress-strain curves of poly(lactic acid)/Poly(butylene adipate-co-terephthalate) polymer alloys (80/20, 70/30, 60/40, 50/50, 30/70) were measured using the tensile split Hopkinson bar method. The effects of mixing ratio and crosslinking agent addition on Young's modulus, maximum stress, elongation at break and dissipated work were examined. The crosslinking agent addition significantly increased elongation at break when the mixing ratio was 50/50 and 30/70. The results were compared with the results of Izod impact tests which measure the fracture toughness of materials. The tensile behavior of specimens during dynamic tensile tests was observed using a high speed video camera. The deformation of the gage area was major. The results of Young's modulus, maximum stress, and elongation at break were compared with the mixture laws of composite materials. The fracture mechanism of the specimens was discussed using observation of the fracture surfaces of the tensile test specimens. When the crosslinking agent was not used, it seemed that the fracture occurred along an interface between the PLA-rich region and the PBAT-rich region. © 2014 Elsevier Ltd. All rights reserved.

Polyamide 11 (PA11) is one of bioplastics (plant-derived plastics or recyclable-resource-based plastics). It is produced from renewable castor seeds. The castor seeds are inedible. This point is important due to the future food insecurity. In order to increase Young's modulus, in the present study, silica nanoparticles were added to PA11. The effects of the addition of silica nanoparticles and the surface treatment of nano silica particles on the stress-strain curves of PA11-based polymer composites at high strain rates were examined. After dynamic tensile tests, the fracture surfaces of the specimens were observed. © The Society for Experimental Mechanics, Inc. 2015.

Based on the structural analysis of sample knitted fabrics and the knit geometric theory, we have built an algorithm that can make three-dimensional structure models for weft knitted fabrics such as welt stitches, tuck stitches, cross stitches, rib stitches and purl stitches. In order to reduce computational complexity, we have set the anchoring point on the diametral plane of yarn in the knitting chart. Drawing from the beginning knitting point to the finished knitting point, a smooth knit curve model can be obtained with the cardinal spline curve. Using this algorithm, we have developed the weft knit three-dimensional structure modeling software that can display the threedimensional model of knitted fabrics including welt stitches; tuck stitches, cross stitches, rib stitches and purl stitches. Our work confirms 3-D modeling of three foundation knits of weft knit (plain stitches, purl stitches, rib stitches), tuck stitches, welt stitches and cross stitches with a commercially available PC. This software can be used by someone with no understanding of knitting to gain an understanding of the knitting process, and determine the structure of a knitted fabric product.© 2011 The Textile Machinery Society of Japan.

A shuttle loom is a weaving machine prevailing in the textile industry. In order to weave a fabric consisting of several kinds of weft yarns with a shuttle loom, we need to design a movement sequence of the shuttle box apparatus. The less distance of the apparatus movements, the more stable operation of the loom is possible. To minimize the distance of the apparatus movements, an algorithm based on dynamic programming was proposed. In this paper, we implement this algorithm and experimentally show that our program finds an optimal solution in less than ten seconds for problem instances with up to 300 weft yarns. © 2014 The Textile Machinery Society of Japan.

This research is aimed at developing a computer aided design system for a traditional tie-dyeing craft named “Shibori”. These products of folk crafts are made with the manual labors and their processes are divided into a lot of practiced hand works. In addition their manufacturing processes are dispersed to different regions. So the practiced hand works of the “Drawing / Pattern carving Shibori” process decrease in number. Producing Shibori products may become difficult because anyone cannot plan the Shibori products in the future. If the “Drawing / Pattern carving Shibori” process is simplified by computerizing, we can record the Shibori technology and can also design Shibori products easily. In this report, therefore, we developed both a CAD system for “Drawing” process in order to simplify its process and keep skilled hands of Shibori products, and a CAM system for “Pattern carving Shibori” process using CAD data. This CAD system is useful for “Mokume-Shibori” to make their stitch images by means of its small scale modification. This report also provides an overview of a CAD system for “Mokume-Shibori” to make their stitch images and a CAM system to make its trial fabric. © 2015 The Textile Machinery Society of Japan.
