The invention provides fabrics that incorporate a cold-adapted trypsin derived from a fish or a crustacean, which trypsin inactivates viruses. The fabrics of the invention may be used in the production of various items of self-sterilizing protective equipment including gowns, sheets, curtains, surgical hats, surgical booties and protective facemasks.

A method for processing a cotton-containing textile waste includes: separating cotton fibers from a batch of the textile waste; pretreating the cotton fibers by soaking in a hydroxide-ion-containing solution to obtain a mixture including pretreated carbon fibers; removing a liquid portion from the mixture to obtain the pretreated carbon fibers; subjecting the pretreated carbon fibers to enzymatic hydrolysis to form a sugary juice containing glucose; and e) adding the liquid portion as part of the hydroxide-ion-containing solution for pretreating the cotton fibers separated from a next batch of the textile waste.

Temperature management bedding systems for mattresses and quilt panels generally include a trilayer of active components including a phase change material applied to a top surface of a flexible substrate thereof, a fire retardant layer underlying the flexible substrate including hydrophilic rayon fibers treated with ammonium polyphosphate; and a vertically oriented fiber batting layer underlying the first retardant layer including an elastomeric binder. The temperature management bedding systems provide heat control and mass transfer of moisture from the bedding surface.

The present application relates to fiber cloth having functional composite particles and a preparation method therefor. The preparation method comprises: placing a solid metal block consisting of functional metal particles into a crucible using an evaporation and condensation process, and heating and evaporating the same into a vacuum physical vapor deposition (PVD) process furnace for condensation; depositing PVD ceramic layers on the outer surfaces of the functional metal particles under the condensed state using a PVD process to form the functional composite particles; and screening the functional composite particles by means of a particle filter and accelerating the particles to bombard the fiber cloth, thereby implanting the functional composite particles into the fiber cloth to form the fiber cloth having the functional composite particles. The functional composite particles in the present application can reduce contact between the internal functional metal particles and external oxygen, slowly release ionic metal ions of the functional metal particles, and prolong the action time of the functional metal particles. According to the present application, by implanting the functional composite particles into the fiber cloth, the fiber cloth with a long lasting antibacterial effect can be obtained.

The present invention relates to functional composite particles and the preparation method thereof. One embodiment of the present invention provides a functional composite particle including an inner core and a shell layer, wherein the inner core is consisted of functional metallic particles and has an outer surface, while the shell layer is a physical vapor deposition (PVD) ceramic layer consisted of biocompatible ceramic materials, and is attached to the outer surface of the inner core. The shell layer is a crystalline structure thereby allowing the ionic functional metallic particles to be sustained-released to the outside of the shell layer from the inner core via crystal boundaries. In the embodiment of the present invention, biocompatible ceramic materials are used to cover the outside surface of the functional metallic particles which have specific functions via the PVD process so as to form functional composite particles. The ionic functional metallic particles of the functional composite particles are sustained-released via crystal boundaries of the shell layer, leading to longer action time of the functional metallic particles.
