The invention relates to devices for surgical use, for healing and for personal hygiene, wherein, among other components, the following are arranged: a layer of organic cotton or bamboo fibres, arranged so as to be in contact with the skin of a user; a layer of non-woven fabric, wherein a central area is occupied by an element consisting of polypropylene fibres and thermostable elastomers, into which nanometric powder of tourmaline is absorbed; and a layer opposite the first layer, formed from materials which allow the ventilation of the device and simultaneously form a barrier against humidity. The invention also relates to the use of the nanometric tourmaline powder in said applications.

The invention provides a flame-retardant and antibacterial nylon wig fiber and a preparation method thereof, comprising the following weight ratio of 85-95% modified nylon, 2-5% of a flame retardant, 0.6-5% of a synergistic flame retardant, and an antibacterial agent 1.5-8%, dyeing agent 0.2-4%, auxiliary additive 0.2-4%, dispersant 0.5-2%, the wig fiber obtained in the present invention has antibacterial flame retardancy, good smoothness and gloss, excellent elasticity, strong Excellent wear resistance, environmental friendliness and other characteristics, with good market competitiveness.

The invention provides a method for making an antifouling sofa fabric, which belongs to the technical field of home textiles and comprises the following steps: (1) selecting raw materials for spinning; (2) yarn antifouling finishing; (3) warping and sizing; (4) weaving (5) transfer printing; (6) solid color finishing; (7) antifouling finishing; (8) water repellent finishing; (9) bonding: on the upper and lower sides of the sponge The adhesive is applied on the sides respectively, and pressure is applied to the upper base cloth layer, sponge and lower base cloth layer stacked up and down, so that the three are bonded into one; (10) sewing; the yarn processed by the warping and sizing machine The sizing rate on the line is high and the hairiness is small, which can reduce the static electricity generated by the friction between the yarns, effectively reducing the static electricity of the fabric itself, so the woven fabric is not easy to generate static electricity, and relatively difficult to absorb dust. The sofa fabric produced has multiple anti-fouling capabilities, and the anti-fouling effect is remarkable.

The present invention relates to the field of fiber manufacturing, in particular to a copper ion antibacterial fiber and an antibacterial fabric. The fiber includes the following components in parts by weight: 100 parts of polylactic acid slices, 5~ 15 parts, 5-10 parts of hydrophobically modified polyvinyl alcohol, 1-5 parts of silane-capped polyethylene glycol, 1-3 parts of cross-linking agent, 0.01-0.05 parts of initiator and 0-3 parts of functional additives; The amount of copper loaded in the copper-loaded nano borosilicate ceramic powder is 0.01-0.1 wt%. The present invention overcomes the defect that antibacterial polylactic acid fibers in the prior art need to add more antibacterial agents in order to achieve a higher antibacterial effect, and the present invention combines copper particles with nanoporous phosphorus-containing borosilicate having far-infrared emission capabilities The combination of ceramic powder makes it possible to achieve effective antibacterial effect under the premise of extremely low copper particle loading, and the copper ion antibacterial fiber prepared by the present invention has good mechanical properties and water washing resistance, so it can be effectively applied in the field of medical care.
