The invention discloses a one-way moisture-conducting fabric structure. The one-way moisture-conducting fabric structure comprises a ramie and cotton blended fabric bottom layer and porous silica gel patterns, wherein the ramie and cotton blended fabric bottom layer is provided with an inner surface and an outer surface; porous silica gel is adhered to the outer surface; the inner surface is in contact with skin. According to the one-way moisture-conducting fabric structure disclosed by the invention, sweat generated by the surface of a body can be absorbed rapidly and diffuses outside the fabric structure; the moisture absorbing and sweat releasing property and the moisture absorbing and sweat releasing speed are improved; the sticky wetting discomfort feeling generated by the sweating of the surface layer of the skin of a human body is reduced.

Molecularly Imprinted Polymers (MIPs) are utilized to detect diseases and minimize false negative / positive scenarios. MIPs are implemented on a nano-electric circuit in a biochip where interactions of MIPs and an Antigen / Antibody (AG / AB) are detected, and disease specific biomarkers diagnosed. Biomarker detection is achieved with interdigitated gold electrodes in a biochip's microchannel. Capacitance changes due to biomarker interaction with AG / AB electrode coating diagnose diseases in a microfluidic environment. Biofluid passes through the microchannel and exposed to the nanocircuit to generate a capacitance difference and diagnose any specific disease in the biofluid sample. Blood capillary flow in a microchannel curved section experience centrifugal forces that separate liquid from solid. Various blood densities and segments experience different centrifugal effects while flowing through the curved section so serum is separated from various solid matter without using external devices.

The invention discloses a method for preparing a latex-free woven carpet. The second coating layer is filament or spun yarn formed of hot-melt fibers, and the first coating layer is fiber long yarn formed of nylon 6 or nylon 66. Silk or spun yarn, the second covering layer accounts for 20%-50% of the total mass of the composite yarn, the first covering layer accounts for 10%-15% of the total mass of the composite yarn, and the rest is the core yarn. Pile weft. When hot-melt copolyamide fibers are used as bonding materials to produce adhesive-free carpets, and pile yarns made of nylon or wool fibers, when the hot-melt copolyamide fibers are heated above their melting point in the hot-pressing process, they melt, and the fibers The conformation of the macromolecular chain changes, and through the transition of the chain segment, the entire macromolecular chain slips and viscous flow occurs. After curing, the pile and weft yarn as well as the weft and warp yarn are effectively consolidated, which enhances the pull-out strength of the carpet pile and The shape retention and dimensional stability of the carpet, thereby omitting the back glue process in the carpet preparation process, makes the prepared carpet more environmentally friendly.

The invention discloses a preparation method of a machine-woven carpet without adhesive backing process. The second coating layer is filament or staple fiber yarn formed by hot-melt fibers, and the first coating layer is polyester fiber filament or staple yarn. Fiber yarn, the second covering layer accounts for 20%-50% of the total mass of the composite yarn, the first covering layer accounts for 10%-15% of the total mass of the composite yarn, and the rest is the core yarn to obtain the pile weft yarn . When hot-melt copolyester fibers are used as bonding materials to produce adhesive-free carpets, and pile yarns made of polyester fibers, when the hot-melt copolyester fibers are heated above their melting point in the hot-pressing process, they melt, and the fibers The conformation of the macromolecular chain changes, and through the transition of the chain segment, the entire macromolecular chain slips and viscous flow occurs. After curing, the pile and weft yarn as well as the weft and warp yarn are effectively consolidated, which enhances the pull-out strength of the pile and the carpet Excellent shape retention and dimensional stability, thereby omitting the back glue process in the carpet preparation process, making the prepared carpet more environmentally friendly.
