Summary of the invention
The objective of the invention is to propose to carry out the production technology of a kind of fabricating antibacterial Nano knitted dress of preventing acarus of mite-proofing and antimicrobial.
In order to achieve the above object, the production technology of a kind of fabricating antibacterial Nano knitted dress of preventing acarus that the present invention describes, it comprises silver and titanium dioxide powder powder material, with granularity be 30-50nm Nano Silver and titania powder dispersion of materials, be emulsified in the ethanol water solvent, and adopt tween and tannic acid to carry out nanometer Ag and nano-TiO
2Nanometer finishing agent is made in the emulsification of powder and dispersion, knitwear is immersed in the nanometer finishing agent again, bakes knitwear then, nanometer Ag and nano-TiO
2Dusty material just is adsorbed onto in the fabric securely.Optimized consumption is that Nano Silver and titania powder consumption are 3 parts in the nanometer finishing agent, and wherein the ratio of Nano Silver and nano titanium oxide is 3: 1,9 parts in the water in the nanometer finishing agent, 4.5 parts of emulsifier tweens, 15 parts of ethanol, 9 parts in tannic acid.During processing, the nanometer finishing agent that emulsification is good is poured in the soak for preparing at 1: 10 by fabric weight, about 40 ± 2 ℃ of liquid temperature, stir, the clothes after washing and the dehydration are evenly put into soak soak, require all clothes all to submerge in the soak, soak after 30 minutes, dewater, then by its normal stoving process requirement oven dry, in 100 parts of fabric weights, Nano Silver and nano titanium oxide account for 2 to 3 parts.
The production technology of a kind of fabricating antibacterial Nano knitted dress of preventing acarus that the present invention proposes mainly comprises the dispersion, optimization consumption, functional processing technology of scope, the nanoparticle of nanoparticle etc.
Nanometer Ag is the contact antiseptic, by free Ag
+Destroy the sulfydryl of zymoprotein in the bacterial body and make the enzyme loss of activity, reach the purpose of killing bacteria.Nano-TiO
2Utilize the natural daylight can catalytic decomposition bacterium and organic pollution, have characteristics such as high catalytic activity, good chemical stability and heat endurance, non-secondary pollution, nonirritant, safety non-toxic.The photocatalytic applications technical matters is simple, with low cost, and can be of value to the ecological natural environment for a long time, is one of environmental protection catalyst that has most DEVELOPMENT PROSPECT.Adopt nano-TiO in the present technique
2Carry out compoundly preparing the mite-proofing and antimicrobial finishing agent with nanometer Ag,, acarid is played the effect that suppresses and kill, improved simple greatly by nano-TiO even in the environment that light-catalyzed reaction can not take place, can play the effect of inhibition so equally to bacterium
2Carry out light-catalysed limitation.As long as add a small amount of nano-powder, just can reach good effect, thereby production cost is lower in process of production.
(24 hours the mite rate of driving is 90.9% for acarid higher repellent effect to be arranged by the knitwear of the present invention arrangement, the mite rate of driving of washing after 50 times 24 hours is 79.4%) and higher fungistatic effect (12 hours bacteriostasis rate is 95.28%, the bacteriostasis rate of washing after 50 times 12 hours is 64.19%), all reach international standard, kept the original style of fabric simultaneously.
The specific embodiment
In the specific implementation, at first:
(1) selects suitable nano inorganic mite-proofing and antimicrobial finishing agent.Make selected mite-proofing and antimicrobial finishing agent should satisfy following requirement:
1. the adhesion with fabric is strong, anti-rinsing, the mite-proofing and antimicrobial with normal effect;
2. human body is had no side effect, free from environmental pollution, security is good;
3. be easy to use, do not influence the quality and the style of fabric.
(2) dispersion of nanoparticle.Verify by experiment, select optimum experimental program, under this experimental program and dispersion theory guidance, select suitable dispersant and optimum dispersion prepared nanometer mite-proofing and antimicrobial composite finishing agent.
(3) mite-proofing and antimicrobial check.Test by the self-cleaning effect of fabric after selecting different finishing agent consumptions to arrangement, and determine the optimum amount of nanometer powder in the self-cleaning arrangement process by its effect.
(4) method of putting in order behind the mite-proofing and antimicrobial.Must select one not only to be fit to enterprise's production but also can to make nanometer mite-proofing and antimicrobial finishing agent fully adsorb and adsorb uniform method for sorting.Guarantee that simultaneously the textiles after the arrangement has good feel and gloss.The embodiment that provides thus is as follows:
1, fabric is weighed
Weigh up the clothes weight (weight before the washing) that will put in order, and record.Add the detergent washing then, dehydration.
2, calculate the weight (representing) of required nanometer powder with M
The powder consumption is 3% of a fabric weight, and wherein the ratio of Nano Silver and nano titanium oxide is 3: 1,

4, the weighing of nanometer powder and dispersant
Nanometer powder, each auxiliary agent are carried out weighing.
5, preparation composite Nano finishing agent
1, after being mixed, pours in the beaker load weighted nanometer powder.
2, in beaker, add water after, stir, be made into weak solution.
3, in beaker, add ethanol, tween and tannic acid, and ceaselessly stir.
4, add an amount of water again, behind the dilute solution, be placed on the mulser fully emulsified.
5, emulsification.Beginning is selected suitable speed (remaining on about 2400 rev/mins of low speed, 10 minutes) during emulsification, quickens then, during 5000 rev/mins of maintenance emulsification rotating speeds, carries out emulsification and is not less than 30 minutes.
6, treatment process
The nano finishing liquid that emulsification is good is poured in the larger container, and (fabric weight: dressing liquid weight) be made into dressing liquid, and keep 40 ± 2 ℃ of water temperatures, stir, the pH value of adjusting dressing liquid was 7 by 1: 10.Add the clothes that to put in order, require all clothes all to submerge in the soak, soaked 30 minutes, dewater then.
7, oven dry
Clothes after the arrangement of dehydration are dried according to normal stoving process.
8, steam boiling hot typing
Steam boiling hot typing to putting the back clothes in order, guarantee its clothes fashion style.
