Description
Technical field
The present invention relates to a kind of brassiere, in particular, the nano-antibacterial porous breathable bra cup and the manufacture method thereof that relate to a kind of nano-antibacterial ventilating bra and be used for this brassiere.
Background technology
Brassiere is the necessity of women 's life; the general utility functions of brassiere are protections and orthopedic; but human body there is not medical care effect; sweat stain in the daily life or milk stain can cause harmful bacteria a large amount of breedings in brassiere (the especially brassiere of gas permeability difference); and some breast disease of initiation that may be direct or indirect; thereby good permeability and have the brassiere of antibacterial effect, can reduce the generation of breast disease effectively.
Present commercially available brassiere, its cup generally adopts the foam sponge material, though this brassiere manufacturing is simple, cost is low, comfortable and easy to wear, airtight; Commercially available have a kind of brassiere that adopts silk flosssilk wadding material cup to make, and its gas permeability is relatively good, but poor stability is yielding behind the following water; Other has a kind of continuous brassiere of making of sandwich that adopts, and its permeability is good, washes the indeformable nondiscolouring in back, but because it is to adopt moulded section, dress property is bad.
The way of much utilizing brassiere that breast is kept healthy is also arranged at present.Existing health-care bra mainly is magnetic therapy brassiere and medication brassiere.The magnetic therapy brassiere mainly is to add magnetic sheet, magnetic bead or crystal in the brassiere interlayer, and Chinese patent CN1277825 discloses a kind of like this brassiere, but the brassiere that this method is made can influence snugness of fit; In the brassiere that also has automatic massage device or ultrasonic oscillator are housed, this brassiere complex structure, weight increases, washing inconvenience.Chinese patent ZL86200838, CN2633030Y, CN2512260Y and CN2076765U disclose a kind of Chinese medicine brassiere, and it is to utilize the external treatment with Chinese medicine theory, places Chinese medicine in brassiere, by the acupuncture point meridian conduction, reach the purpose of treatment; But this method is subject to the transmission of medicine and infiltration and affects the treatment, and also exists EDD short, and therapeutic domain is little, shortcomings such as complex process and gas permeability difference.Patent CN2421856Y discloses the antibiotic brassiere of a kind of shell-fish, but only is that its nonwoven internal layer has adopted part shell-fish antimicrobial yarn to make by acupuncture or water thorn, does not then have antibacterial functions as for the cup as the brassiere main body.
Along with the development of nanosecond science and technology, nanometer technology has also obtained widely in textile industry and has used.Chinese patent CN01128377.7 discloses a kind of functional rayon staple, and it is that crude tourmaline powder and the Zinc oxide powder of particle diameter below 100 nanometers evenly is blended in the artificial viscose solution carrier, obtains the antibacterial artificial fiber through processing such as spray silks.Chinese patent CN02110160.4 discloses the nano particle anti-bacterial fibre, its nano particle that adopts is the natural crystal through processing, as zeolite, very ice stone, particle size range is the 100-300 nanometer, also can be for synthetic metal oxide, as zinc oxide, titanium oxide, cuprous oxide and metal sulfide, as copper sulfide, cuprous sulfide, chromic sulfide, ferrous sulfide etc., its particle size range is the 5-150 nanometer.Chinese patent CN1587454A also discloses a kind of nano silver particles antibacterial viscose fiber; it is that particle diameter is joined in the spinning solution less than the silver particles of the 100 nanometers form with colloid aqueous solution; and the mixture that has added amino acid or amino acid and hydroxypropyl methylcellulose is as colloid protective agent, and a wet spinning spray silk technological forming obtains the durable antibiotic fiber routinely then.
But also there is not correlation technique that nano anti-biotic material is applied directly in the middle of the one-shot forming bra cup at present, not open about the product or the technology of nano-antibacterial ventilating bra yet.
