Abstract
The invention relates to a preparation method of antibacterial conductive cotton fiber. Cotton fiber short fiber loose wool is used as a raw material. The method comprises the following steps that the cotton short fiber is deoiled, coarsened and subjected to sensitization pretreatment, a low concentration silver nitrate-ammonia water solution is added for activation, then chemical silvering is carried out, a chelating ligand agent is added during chemical silvering to replace some ammonia water, and high-temperature solidifying treatment is carried out after chemical silvering. The operation is simple, the technological performance is stable, energy consumption is small, and industrial production is easy. By the adoption of the antibacterial conductive cotton fiber, the plating layer combining firmness degree is high, the conductivity is good, the specific surface area resistance reaches 10-100 ohm/cm, the properties of common cotton fiber are reserved, and the cotton fiber can be used as the antibacterial and conductive cotton fiber, and can be made into antibacterial conductive cotton yarn after being matched with different proportions of common cotton short fiber to be used for various textiles.
Description
Technical field
The present invention relates to a kind of preparation method of antibiotic conductive cotton fiber, the method, by making matrix have good electric conductivity at matrix surface plating layer of metal silverskin, belongs to new textile material field.
Background technology
Silver plated fiber is a kind of high performance functional fibre, and the function such as the antibacterial and deodouring of its uniqueness, anti-electromagnetic radiation, antistatic, regulate body temperature is attracted attention by people.The outer plating technology of fiber mainly contains chemical plating, plating and Vacuum Deposition three class.Adopt Electroless Silver Plating have technique simple, be applicable to the advantages such as irregular matrix material, cost are lower, but it is difficult to there is reaction in current Electroless Silver Plating, control bath stability is poor, and silver-plated price is more expensive, the conductive fiber coating problem that not evenly binding strength is not high of preparation.
Before making the present invention, Chinese invention patent, CNl311369A, disclose a kind of chemical silver plating method of organic fiber, take silver ammino solution as silver plating liquid, before silver-plated, raw material is cleaned in acetone soln, then surface activation process is carried out, catalyst P dCl2 catalysis with salpeter solution and hydrochloric acid solution.The method use this organic solvent of acetone, have employed again precious metal palladium as catalyst, cost compare is high.Chinese invention patent CN100570047C discloses a kind of preparation method of high-performance conductive fiber, using sodium potassium tartrate tetrahydrate as reductant, adopts oxalic acid solution to soak solidification.Have employed organic solvent 2-dichloroethanes or dimethylbenzene equally as alligatoring agent, cost compare is high.Chinese invention patent CN101012552A discloses a kind of stable fibre chemistry silver-coating method that can repeatedly supplement, and using formaldehyde as reductant, has reacted rear interpolation ammoniacal liquor and formaldehyde, continues chemical silvering.Formaldehyde toxic and volatile, adopts formaldehyde to pollute.
The base material more than invented is all the chemical fibres such as terylene, nylon, has no precedent the cotton silver-coating method as base material.Appearance of the present invention, has filled up national blank.
Summary of the invention
Problem to be solved by this invention is the deficiency overcoming prior art existence, and provides a kind of preparation method of cotton antibiotic conductive fiber.
The technical solution adopted in the present invention is:
A kind of preparation method of antibiotic conductive cotton fiber, fall apart hair for raw material with cotton fiber short fiber, comprise the steps: to deoil to cotton short fiber, alligatoring, sensitization pre-treatment, adds low concentration silver nitrate-ammonia spirit activation, then carries out chemical silvering, add chelating ligands agent when chemical silvering and replace partial ammonia water, after silver-plated, carry out hot setting process.
Preferably, described cotton short fiber roughening process adopts alkali treatment, and temperature is 50 DEG C ± 5 DEG C, and dip time is 30 ~ 40min.
Preferably, described alkali is NaOH, and the concentration of NaOH is 30 ~ 60ml/l.
Preferably, described sensitization pre-treatment, floods 15 ~ 18min under adopting the stannous chloride solution normal temperature of 5 ~ 16g/L, and the cotton fiber after then adopting the sodium bicarbonate solution of 1g/L to rinse stannous chloride dipping, clarifies to cleaning solution.
Preferably, after described silver nitrate-ammonia spirit activation, the formula carrying out chemical plating liquid is composed as follows:
Reducing solution is filled a prescription: glucose 10 ~ 15g/L;
Oxidation solution is filled a prescription: silver nitrate 10 ~ 20g/L;
Ammoniacal liquor: appropriate;
Chelating ligands agent 0.1 ~ 1.5g/L.
Preferably, the chelating ligands agent added in described chemical silvering is nitrilotriacetic acid salt, citrate or pyrophosphate.
Preferably, described silver-plated after carry out hot setting process, hot setting is temperature is 80 ~ 100 DEG C, time 5 ~ 7min.
The principle of foundation of the present invention is:
1, cotton short fiber roughening treatment can adopt acid or alkali treatment, but base extraction affects the mechanical property of fiber, and the easy etching apparatus of hydrochloric acid, nitric acid is more expensive, relatively good with NaOH.
2, when carrying out sensitized treatment with stannous chloride, not very even, easily being washed, the present invention adds sodium bicarbonate solution cleaning, and solution ph is raised, and stannous chloride forms nanogel and is deposited on cotton fiber surface, formed relatively more firm, more uniform sedimentary deposit.Thereafter adopt the activation of low concentration silver ammino solution, strengthen the adhesion of matrix and silver, make silver-plated after be not easy to fall down.
3, chemistry crosses in formula of liquid and adds chelating ligands agent, for stable plating solution, reduces surface porosity factor and roughness, makes coating surface even.The Ag particle of separating out is less, forms nano-Ag particles, can anti-oxidation, reduces the impurity that coating is separated out, and increases the uniformity that Argent grain is separated out.
Compared with prior art, the present invention has following obvious advantage:
NaOH corrosivity is lower, low price, may be used for the alligatoring of fiber, the nano-colloid of tin ash is formed during sodium bicarbonate cleaning stannous chloride, Nano silver deposition can be helped even, add chelating ligands agent in plating solution, the uniformity of coating and the binding strength between itself and matrix fiber can be significantly improved.The present invention is simple to operate, processing performance is stablized, cost is low, and power consumption is few, is easy to suitability for industrialized production, adopt antibiotic conductive fiber prepared by the present invention, coating binding strength is high, and electric conductivity is good, and specific area resistance reaches 10-100 Ω/cm, and retain the characteristic of original fiber, can use in multiple textile material.
