The invention discloses a multifunctional fabric with moisture absorption and perspiration, antibacterial and antistatic properties and a production method thereof. The multi-functional fabric is made of 95-99% multi-functional blended yarn and 1-5% stainless steel anti-static yarn or conductive anti-static yarn; the multi-functional blended yarn is made of moisture-wicking fiber 50-80%, cotton Fiber 15-45% and silver fiber 5-10% are blended; stainless steel antistatic yarn is made of moisture-wicking fiber 35-45%, cotton fiber 10-30%, silver fiber 3-7% and stainless steel fiber 25-40% % blended; conductive yarn antistatic yarn is twisted from 3-5% organic conductive yarn and 95-97% multifunctional blended yarn. The multifunctional fabric produced by the invention has antistatic function, moisture absorption and perspiration function and antibacterial function, which can not only ensure the antistatic function of the fabric, but also greatly improve the air permeability of the fabric, improve the wearing comfort of the fabric, and have good antibacterial function.

The invention discloses water-dispersible environment-friendly waterborne wood coating with insect-killing and anion-releasing properties and a preparation method thereof; the waterborne wood coating comprises, by weight, 50-80% of water-dispersible modified acrylic emulsion, 0.2-0.5% of a mildew-proof bactericide, 0.2-0.5% of a defoaming agent, 0.2-0.6% of a dispersing wetting agent, 0.2-0.6% of a base wetting agent, 1.5-2.5% of a leveling agent, 3-6% of a film-forming aid, 0.05-0.2% of a multifunctional aid, 0.5-2% of a co-surfactant, 2-4% of an antibacterial insecticidal agent, 3-6% of anion powder, 0.2-0.5% of anti-adhesion aid, 0.2-1% of a polyurethane thickener, 0-20% of filling material, and the balance of deionized water, wherein the anion powder is yellow river jade anion powder, the antibacterial insecticidal agent is compounded from activated crystal antibacterial slow-release capsules and nano silver. The waterborne wood coating of the invention is waterborne, nontoxic, environmentally friendly, highly decorative, high in hardness, fine to touch, and short in drying time, and has the effects of preventing and killing insects, releasing anions and other effects.

The invention belongs to the technical field of decorative sheet machining, and relates to PVC floors, in particular to a one-time forming type PVC composite floor manufacturing process. The manufacturing process comprises the following steps that parts of a surface layer and parts of a bottom layer are mixed by weight, put onto the upper layer of a co-extrusion double-cone machine and sequentially enter the upper layer and the bottom layer of a calendaring forming machine; parts of a core layer are mixed by weight, put onto the lower layer of the co-extrusion double-cone machine, then subjected to foaming at 210-220 DEG C and enter the middle layer of the calendaring forming machine; one-time calendaring composite forming is conducted, meanwhile, a polyvinyl chloride (PVC) heat transfer film, a polypropylene (PP) heat transfer film or a polyethylene (PE) heat transfer film veneer which is formed through calendaring of the calendaring forming machine is used as a decorative layer to bepasted on the upper surface of the surface layer, and one-time roll forming is conducted through a four-roller press or a five-roller press; and integral forming is achieved through die pressing andcompositing, and one-time forming, cooling and slitting are conducted. The one-time forming type PVC composite floor manufacturing process is simple and high in controllability, a manufactured PVC composite floor has the advantages of being free of formaldehyde, environmentally friendly, non-poisonous, safe, dampproof and the like and has certain anti-microbial and anti-mold effects.
