Abstract
Non-woven cloth or its fibre is soaked in the water solution of DC-5700 for 10 min, cross-linked at 120-130 deg.C for 5 min, so that on the fibre of non-woven fabric are grafted cation radicals, whose positive charges attract negative charges in bacteria to result in physical antiseptic and bactericidal effect. With lasting wide-spectrum antiseptic effect and without harmful effect on body, the said physically antiseptic no-woven fabric is used in life and medicine.
Description
The invention belongs to field of papermaking, it relates to a kind of manufacture method of antibacterial nonwoven cloth made.
Paper is and one of the closest articles for use of human lives's relation, and as the nonwoven fabric of one of paper for daily use in the paper, along with the raising of people's living standard enters various fields in life more day by day, brings convenience to people's life.But hygienic issues such as the antibiotic sterilization of nonwoven fabric, perplexing manufacturing and user always, although disinfecting in manufacture process through strictness, but in accumulating, sale and use, all cause germ contamination unavoidably, and make bacterium grow in a large number, breed, promptly influence health, also can be owing to reason such as go mouldy cause huge waste, and limited nonwoven fabric being extensive use of in hygienic material.
The objective of the invention is to promptly not influence serviceability, the scope of application reaches the nonwoven fabric of broad-spectrum antiseptic sterilization again widely with physical method.
The object of the present invention is achieved like this: after nonwoven fabric or its fiber are carried out clean, be that the aqueous solvent of the DC-5700 of the 3-that contains reactive functional groups (trimethoxy silane base) propyl-dimethyl octadecyl aliquat of 0.5-1% and an amount of softening agent evenly is sprayed at and makes it drenched on nonwoven fabric or its fiber with concentration, through under 120 ℃ of-130 ℃ of conditions, made in crosslinked 5 minutes again after ten minutes the non-woven fabrics fiber surface evenly the non-dissolution type of parcel one deck have a cationic antibacterial material.
Below with the be fabricated to example of sanltary towel with antibacterial nonwoven cloth made: with amine synthetic fibre, acrylic class nonwoven fabric after washing, rinse, drying, with component is that the DC-5700 of 0.5-1% and the aqueous solvent of an amount of softening agent evenly are sprayed on the nonwoven fabric, and the DC-5700 concentration in the aqueous solvent is that the 0.5-1% percentage by weight is as the criterion with the adsorbance of DC-5700 on the control finished product antibacterial nonwoven cloth made.The nonwoven fabric that sprays after drenching was placed 10 minutes, make its absorption more even, be placed under 127 ℃ of environment crosslinked 5 minutes again, the control of this temperature and time, the original physical properties of nonwoven fabric own is sustained damage, be wrapped in fiber surface securely after making antiseptic DC-5700 dehydrating condensation again.Because DC-5700 is a kind of 3-(trimethoxy silane base) propyl-dimethyl octadecyl aliquat that contains reactive functional groups, its structural formula is as follows:
Separate out methyl alcohol in the trimethoxy silane base of its left end after the methoxyl group hydrolysis and form silanol, reaction equation is as follows:
The hydroxyl of silanol and fiber surface forms covalent bond, CATION is inhaled into ionic bond mutually with negative electrical charge, covalent bond and ionic bond form and fiber strong bonded, its antibiotic sterilization mechanism is such: cell membrane, the cell membrane of nearly all bacterium, fungi etc. all are made up of the Phospholipids bimolecular film, be elecrtonegativity, and the CATION (N of grafting on the antibacterial nonwoven cloth made fiber
) group makes antibacterial nonwoven cloth made produce the static positive charge, inhales principle mutually according to positive and negative charge, bacterium will be adsorbed constraint, has restrained breathing function then, until death.Also have a kind of sterilization mechanism to be: under the electric field graviational interaction, the negative electrical charge skewness on cell membrane and the cell membrane causes deformation, and generation physics breaks and promptly dissolves phenomenon.In addition, positive and negative charge is inhaled mutually, causes magnetic interference, has destroyed the genetic permutation and combination of bacterium, makes the bacterium can't schizogamy.Owing to be physical sterilization, human body is not had any harmful effect, and bacteriostasis rate can reach 99.99% to 100%.And because its non-stripping character, even through repeatedly washing, bacteriostasis rate is still more than 90%.
Because characteristics such as the physical sterilization of antibacterial nonwoven cloth made of the present invention and non-stripping property, so antibacterial range wide (almost can kill all harmful bacteriums), the antibiotic time is long.Human body there is not any adverse effect.Can be not influential to original color of nonwoven fabric and intensity.Because these characteristics, antibacterial nonwoven cloth made can be widely used in every field such as life, medical treatment, health.
Claims (1)
- A kind of manufacture method of antibacterial nonwoven cloth made of paper-making industry, it is characterized in that: after nonwoven fabric or its fiber clean, with concentration is that 0.5-1% is that the aqueous solvent of the DC-5 700 of 3-(trimethoxy silane base) the propyl-dimethyl octadecyl aliquat that contains reactive functional groups and an amount of softening agent evenly is sprayed on nonwoven fabric or its fiber it is soaked into, through after ten minutes under 120 ℃ of-130 ℃ of conditions crosslinked 5 minutes again, make the non-woven fabrics fiber surface evenly the non-dissolution type of parcel one deck have a cationic antibacterial material.
