Outline of Final Research Achievements

As material of protective clothing, properties of leno fabrics are examined. From early times, leno fabrics are well known as a kind of summer clothing material. They have a level of strength even though their high air ventilation. These features are realized by yarn locking structure; weft yarns are woven during the interchanging of paired warps.
In this study, a novel protective clothing material is prototyped using high performance fibers by leno weaving technique. The fabric is exposed air ventilation test and stab proof test. The results show that it is possible to these desirable performance at a same time based on the leno fabric principle.

Academic Significance and Societal Importance of the Research Achievements

警察官等が安全に職務を遂行する上で防護服は重要な装備である。日本においては銃刀法が徹底されているため武器によるリスクは低いが、アイスピックや釘のように法の規制外の日用品でも先端が鋭利で突刺しの危険が懸念されるものがある。このように防護服の耐突刺し防護性の向上と着用時の不快感低減が望まれる。
本研究はこの相反する要求を両立する技術としてこれまであまり検討されてこなかったテキスタイル技術の側面、特に絡み織について検討し、これが着用時不快感の低減と高度な防護性の両立に有効であることを見出した。
