SYNTHETIC LEATHER
Provided is a synthetic leather including a fibrous substrate, a porous resin layer provided on the fibrous substrate, and a non-porous resin layer provided on the porous resin layer. The synthetic leather has a thickness of 800 μm or more, and a vertical cross-section of the porous resin layer has a pore area ratio of 25% or more.
TEXTILE STRUCTURE
A textile structure includes a fiber-based layer and a glue layer. The fiber-based layer has meshes and includes fiber of which basic composition is cellulose. The glue layer penetrates into the meshes.
Touch display leather and leather structure
A touch display leather and a leather structure thereof are provided. The leather structure includes a diffusion layer, a foam layer and a fabric layer. The diffusion layer includes optical powder dispersed therein. The foam layer is disposed on the diffusion layer, and the foam layer is foamed to provide a leather feel. The fabric layer is disposed on the foam layer, and the fabric layer is color-matched and embossed to present a leather pattern. Base materials of the diffusion layer, the foam layer, and the fabric layer are all at least one material selected from the group consisting of polyvinyl chloride (PVC), polyurethane (PU), and polyolefin (PO), and the leather structure has a light transmittance between 2% and 30%.
NON-SOLVENT 2K POLYURETHANE ARTIFICIAL LEATHER COMPOSITION, ARTIFICIAL LEATHER PREPARED WITH SAME AND PREPARATION METHOD THEREOF
A non-solvent two-component polyurethane artificial leather composition is provided. The polyurethane composition comprises (A) a polyurethane-prepolymer component, comprising one or more polyurethane-prepolymers prepared by reacting at least one polyisocyanate compound with at least one first polyol, wherein the polyurethane-prepolymer comprises at least two free isocyanate groups; and (B) a polyol component, comprising at least one second polyol; wherein the polyol component further comprises an encapsulated foaming agent comprising at least one foaming core phase encapsulated within an outer shell. The polyurethane leather product derived from the polyurethane composition exhibits enhanced stability, mild bubble generation and improved cost effectiveness. A polyurethane leather product prepared with said composition and the method for preparing the same are also provided.
Composite scaffold for the repair, reconstruction, and regeneration of soft tissues
A composite scaffold having a highly porous interior with increased surface area and void volume is surrounded by a flexible support structure that substantially maintains its three-dimensional shape under tension and provides mechanical reinforcement during repair or reconstruction of soft tissue while simultaneously facilitating regeneration of functional tissue.

Woven fabric
A comfortable fabric with a strong three-dimensional effect is woven from warps and wefts. The warps and the wefts are woven into a 1/1 pattern, wherein the warp density is 11 threads/cm and the weft density is 10 threads/cm. The warps and the wefts each include a cationic dyeable polyester hollow yarn that comprises two different polyester yarns which can be dyed with two different colors. The warps and wefts comprise big-belly yarns and the cationic dyeable polyester hollow yarns. The resulting fabric has protruding patterns, a strong three-dimensional effect, good air permeability, a rough feel to the touch, and a unique aesthetic appearance.
