Thermal insulation sheet and manufacturing method therefor

A thermal insulation sheet is used that includes a fiber, a silica aerogel contained in the fiber, and a fibrous cavity. A method for manufacturing a thermal insulation sheet is used that includes: an impregnation step of impregnating a silica aerosol in a nonwoven fabric substrate containing a fiber that is insoluble in an acidic solution, and a fiber that is soluble in the acidic solution; a gelling step of gelling the silica aerosol; a hydrophobizing step of hydrophobizing the gel; and a drying step of drying the gel. The fiber that is soluble in the acidic solution is dissolved in the hydrophobizing step.

POLYAMINO ACID-GRAFTED MODIFIED WATER-REPELLENT FABRIC AND PREPARATION METHOD THEREFOR
20230332347 · 2023-10-19 ·

An amino group is grafted to a fiber surface, the ring-opening polymerization of aniline acid anhydride is initiated by the amino group on the fiber surface to form a graft chain, and a water-repellent fabric the fiber surface of which is modified by polyamino acid is prepared. The fabric treatment uses an amino group pre-grafted on a fiber surface as an initiator in the liquid phase, and initiates (substitutes), by means of ring-opening polymerization (ROP), aniline acid anhydride to complete graft polymerization on the fiber surface. The production conditions are mild, the preparation process of the product is simple, and operation is safe. In the disclosed water-repellent fabric obtained by chemical grafting, a functional protective layer on the fiber surface is covalently bonded to the fiber, thereby having excellent fastness without affecting the wearability of the fabric, thus the problem of a water-repellent fabric having poor fastness is solved.

Super-hydrophobic fabric and preparation method thereof

The present invention provides super-hydrophobic fabrics and a preparation method thereof, and belong to the field of textiles. The super-hydrophobic fabrics are obtained by finishing Pickering emulsion formed by amphiphilic particles stabilizing low-surface-energy substances in water. Via a one-step finishing method using Pickering emulsion technology, facile preparation of durable super-hydrophobic fabrics is realized. The static contact angle between the finished fabric surfaces and water droplets is greater than 150 degrees, and the water droplets can roll off easily; and after being subjected to 30 times of standard washing tests, the finished fabrics still maintains excellent water repellency. In addition, the Pickering emulsion preparation and finishing process of the present invention are environmentally friendly, pollution-free, facile to operate and widely applicable.
