Problems solved by technology

[0004] The non-woven materials obtained by the aforementioned CN100535220C and CN1253615C have the advantages of antibacterial and bactericidal, but because the main components are still polyester fibers and polypropylene fibers as non-woven raw materials and / or natural fibers, so it does not have the effects of deodorization, purification, filtration and adsorption of toxic and harmful gases in the air, etc.

Embodiment 1

[0025] please see figure 1 .

[0026] A) To prepare nano-silver antibacterial fibers, first put viscose fibers with a high whiteness (also called fineness) of 1.5dtex and a length of 40mm into a nano-silver solution with a mass percentage concentration of 1000ppm for 10 minutes, and then carry out Dehydration and drying, the drying temperature is controlled at 160°C, the drying time is controlled at 10min, and the moisture content after drying is controlled at 9%, to obtain nano-silver antibacterial fibers, wherein: the aforementioned nano-silver solution with a concentration of 1000ppm is Obtained by diluting a high-concentration dispersion of nano-scale silver particles with a particle size of 5-20nm and a concentration of 50,000ppm;

[0027] B) Opening, the activated carbon fibers obtained from commercial channels are opened through the usual opener in the non-woven product production industry, and the nano-silver antibacterial fibers obtained in step A) are also opened by...

Embodiment 2

[0034] Change the fineness (i.e. fineness) of the high-whiteness viscose fiber in step A) to 1.8dtex, the length of the viscose fiber to 35mm, the mass percentage concentration of the nano-silver solution to 500ppm, and the soaking time to 30min, change the drying temperature to 130°C, change the drying time to 30min, change the moisture content after drying, that is, the moisture content of the nano-silver antibacterial fiber to 14%; change the parts by weight of the activated carbon fiber in step C) to 90 Change the weight parts of nano-silver antibacterial fiber to 10 parts; change the gram weight of the single-layer cotton net in step D) to 10g / ㎡, and change the number of layers of cotton net laying to 5 layers; step E) change Spunlace with a water entanglement machine to obtain a silver charcoal deodorizing and antibacterial nonwoven fabric with a gram weight of 50 g / ㎡, and the rest are the same as the description of Example 1.

Embodiment 3

[0036] Change the fineness of the high-whiteness viscose fiber in step A) to 1.65dtex, the length of the viscose fiber to 38mm, the mass percentage concentration of the nano-silver solution to 750ppm, the soaking time to 20min, and the drying temperature to 145 DEG C, the drying time is changed to 20min, and the moisture content of the fiber after drying is changed to 12%; the parts by weight of activated carbon fibers in step C) are changed to 85 parts, and the parts by weight of nano silver antibacterial fibers are changed to 15 parts; change the weight of the single-layer cotton net in step D) to 15g / ㎡, and change the number of layers of cotton net to 15 layers; the silver charcoal deodorant and antibacterial non-woven fabric obtained after step E) is pierced The grammage is 225g / ㎡, and all the other are with the description to embodiment 1.

Abstract

The invention discloses a silver / carbon deodorizing antibacterial non-woven fabric and a preparation method thereof, belonging to the technical field of non-woven fabrics. The silver / carbon deodorizing antibacterial non-woven fabric is prepared by mixing an active carbon fiber and a nano silver antibacterial fiber. The method comprises the following steps: soaking a viscose fiber in a nano silversolution; dehydrating and drying the soaked viscose fiber; controlling the drying temperature, the drying time and the moisture content of the dried viscose fiber to obtain the nano silver antibacterial fiber; opening the active carbon fiber and the nano silver antibacterial fiber by an opening machine; introducing the opened 80-90 parts by weight of active carbon fiber and the opened 10-20 parts by weight of nano silver antibacterial fiber into a cotton mixing machine and uniformly mixing to obtain the silver / carbon deodorizing antibacterial fiber mixture; carding the silver / carbon deodorizing antibacterial fiber mixture by a carding machine, and spreading the mixture into a cotton net by a lapping machine; and needling the cotton net by a needling machine or a spunlaced machine to obtain the silver / carbon deodorizing antibacterial nonwoven fabric. The silver / carbon deodorizing antibacterial non-woven fabric has a good effect in suppressing and killing the bred bacteria, mould and the like, and is environment-friendly.

Description

technical field [0001] The invention belongs to the technical field of non-woven fabrics, in particular to a silver charcoal deodorizing and antibacterial nonwoven fabric, and also relates to a preparation method of the silver charcoal deodorizing and antibacterial nonwoven fabric. Background technique [0002] The known antibacterial non-woven fabric is to add the drug fiber soaked and dried through the deodorant antibacterial agent solution in the polyester fiber, polypropylene fiber and / or natural fiber as cotton fiber as the main raw material, and the drug fiber can be the aforementioned Polyester fibers, polypropylene fibers and / or cotton fibers can also be other similar fibers such as polylactic acid fibers and the like. Mix the medicinal fiber with other fibers such as one or more of the aforementioned fibers (referred to as cotton blending in the industry), and open it with an opener, comb it with a carding machine, lay the net with a web-laying machine, and then nee...
