A hollow fiber membrane including a dense layer at least on an inner surface side of the hollow fiber membrane, in which when the inner surface of the hollow fiber membrane is observed under an atomic force microscope, a plurality of groove-like recesses oriented in a lengthwise direction of the hollow fiber membrane are observed, an aspect ratio defined as a ratio of a length to a width of each of the recesses is greater than or equal to 3 and less than or equal to 30, a yield strength of the hollow fiber membrane in a dry state is greater than or equal to 30 g/filament, and a breaking elongation is less than or equal to 20%/filament.

The present disclosure provides a coaxial fiber comprising a cellulose fiber exterior, and a hollow interior, wherein the aerogel occupies the hollow interior of the cellulose fiber. The present disclosure also provides a method of making the coaxial fiber, and a method of maintain a temperature differential in two zones using the coaxial fibers described herein.

A material is provided which comprises cellulose fine fibers and which is capable of suitably acting on resin or rubber uniformly on a high level, and of generating superior action when added to a resin composition. As such a material, cellulose xanthate fine fibers are contained in a resin composition or a resin dispersion.

The present invention relates to a method for constructing a chromatography test strip for triazophos based on molecular imprinting and electrospinning. The present invention combines electrospinning, molecular imprinting and the immunochromatography test strip technology. Molecularly imprinted T-line (detection limit) is prepared on an NC membrane by electrospinning, and goat anti-mouse IgG is used as C-line (quality control line). With fluorescence changes occurring when triazophos hapten-murine IgG/fluorescein isothiocyanate conjugate (THBu-IgG-FITC) fluorescent probe directly competes with the target triazophos to bind to the molecularly imprinted binding site, a chromatography-fluorescence detection method for triazophos based on molecular imprinting and electrospinning is established. The functional material adsorbing triazophos provided by the present invention adopts a virtual template to avoid template leakage, and can be used in immunochromatography to replace a biological antibody. The functional material has higher selectivity, higher stability, longer service life, and stronger resistance to adverse environment.

The present invention is generally related to a high capacity, high efficiency nonwoven filtration media comprising a gradient pore structure. In particular, the filtration media can comprise thermoplastic synthetic microfibers, fibrillated fibers, staple fibers, and a binder. Furthermore, the filtration media may be produced without the use of glass fibers or microglass fibers. A process for making the filtration media is also provided. Consequently, the filtration media of the present invention does not cause the same issues as conventional filtration media that comprises glass fibers and/or microglass fibers. Moreover, the filtration media can be used to treat fuel, lubrication fluids, hydraulic fluids, and various other industrial gases.

Composite fibers, such as poly(lactic-co-glycolic acid) (PLGA)-cellulose acetate (CA) composite fibers, matrices including such fibers, and methods for making and using such fibers and matrices are disclosed.
