A textile with high weave density which comprises a main-yarn made of a Japanese paper yarn and a sub-yarn thinner than the main-yarn interwoven with each other, wherein the textile has a weave texture structure including warps A and wefts A made of the main-yarn, and warps B and wefts B made of the sub-yarn, wherein in the weave texture structure, warp rows have a repeating row structure where a plurality of warps B are located between two warps A and weft rows have a repeating row structure where a plurality of wefts B are located between two wefts A, and wherein the warps A and the wefts A cross each other in a plain weave texture structure.

Clothing articles formed of melting yarn and non-melting yarn, and system and method of producing such clothing articles. A clothing article includes: a first garment-region which consists of, exclusively, non-melting yarn, wherein the first garment-region has a first level of rigidity; and a second garment-region which comprises a mixture of both (i) non-melting yarn and (ii) stiffed melted-yarn, wherein the second garment-region has a second level of rigidity which is greater than the first level of rigidity. A garment includes multiple garment-regions having different levels of rigidity, wherein each garment-region consists of a different ratio of non-melting yarn to stiffed melted-yarn.

Processes for preparing ultra-high molecular weight polyethylene yarns, and the yarns and articles produced therefrom. The surfaces of highly oriented yarns are subjected to a treatment that enhances the surface energy at the yarn surfaces and are coated with a protective coating immediately after the treatment to increase the expected shelf life of the treatment.
