There are provided a core material for vacuum insulator comprising an organic synthetic fiber, and at least one organic synthetic fiber bonded portion; and a preparation method therefor. In addition, provided is a vacuum insulator comprising the core material for vacuum insulator comprising the organic synthetic fiber, and the at least one organic synthetic fiber bonded portion.

Bone tissue biomimetic materials, biomimetic constructs that can be formed with the materials, and methods for forming the materials and constructs are described. The bone tissue biomimetic materials include electrospun nanofibers formed of polymers that are conjugated with peptides that include acidic amino acid residues. The materials can incorporate high levels of mineralization so as to provide mechanical strength and promote osteogenesis and/or osteoconductivity on/in the bone tissue biomimetic materials. The materials and constructs can be utilized in forming tissue engineered structures for in vitro and in vivo use. Macroscopic bone tissue biomimetic scaffolds formed from the materials can be seeded with osteogenic cells and utilized to develop bone graft materials that can exhibit strength and osteoconductivity similar to the native bone and that exhibit uniform distribution of nutrients in the scaffolds.

The invention relates to a woven fabric comprising a weft yarn, an outer layer with warp yarn A and an inner outer layer with warp yarn B, wherein the weft yarn comprises a combination of individual yarns comprising UHMWPE yarns and individual natural yarns, the warp yarn A comprises at least 50 wt % of a natural fiber, and warp yarn B comprises a combination of individual UHMWPE yarns and individual natural yarns, and said outside and inside layer being at least partially interconnected by the weft yarn. The invention also relates to products comprising said woven fabric such as clothing, lining, sport apparel, and gloves.
