Abstract
The present invention relates to a method for regenerating adsorption activity of active carbon functional fabrics. The present invention comprises: an active carbon regenerating agent is used for processing active carbon functional fabrics in a water bath mode, every liter of water needs 3 to 6mL of the regenerating agent, the temperature of the water bath is 35 to 50DEG C, and the pH value is 9 to 10; the active carbon functional fabrics are soaked in the bath liquid for 45 to 60 minutes and stirred with proper external force in the soaking process. The active carbon regenerating agent is made of the following components: 15 to 25% of polyoxyethylene fatty alcohol sodium ethoxylated lauryl alcohol sulfate (AES), 12 to 20% of fatty alcohol polyoxyethylene ether (AE), 0.1 to 1.5% of carboxylic acid alkyl sodium sulfate (CAS), 0.3 to 2% of sodium aluminosilicate, 0.2 to 3% of polycarboxylate (PCAS), 3 to 8% of cellulose ether, 5 to 10% of sodium stearate, 8 to 15% of sodium citric acid, 8 to 10% of sodium sulfuric acid, 0.2 to 1% of proteinase, 0.5 to 3% of lipase and deionized water as the rest. The present invention has the advantages that the processing process is similar to that of the traditional garment washing method, and the present invention creates conditions for enabling active carbon functional fabrics to become garment face materials with the function of health care and skin cleaning; the present invention is an innovative method for regenerating adsorption activity of active carbon.
Description
Technical field
The present invention relates to a kind of renovation process of charcoal absorption activity, feature relates to a kind of renovation process of active carbon functional fabric adsorption activity.
Background technology
Active carbon has very strong adsorptivity, and the fabric that contains active carbon also has the every characteristic that shows because of adsorptivity.This suction-operated of active carbon will reach capacity after after a while, and promptly every effect performance reduces.Regeneration techniques about active carbon also is many experts and scholars' a research topic at present, as to selecting active carbon that gold, water filtration handle etc., all be with strong acid or high temperature, calcining, it is reactivated, realize regeneration, but these method significant discomfort are used for active carbon functional fabric.And be used for the renovation process of active carbon fibre dimensional fabric, mainly based on heating desorption, the general requirement of its heating-up temperature surpasses 150 ℃, can cause certain damage to fabric like this, reduces service life.Method and the pertinent literature report of regenerative agent, the also not discovery at present of adopting regenerative agent that the adsorption activity of active carbon functional fabric is regenerated.
Summary of the invention
Prop up the place at the deficiencies in the prior art, the invention provides a kind of specially at active carbon functional fabric reach absorption saturated after, make it recover adsorption activity so that the renovation process that recycles.
Technical scheme of the present invention is achieved in that a kind of active carbon regenerative agent of employing carries out water bath processing to active carbon functional fabric, and the consumption of described regenerative agent is every premium on currency 3～6mL, and bath temperature is 35～50 ℃, and pH value is 9～10; Active carbon functional fabric is immersed in the above-mentioned body lotion, and soak time is 45～60min, stirs with suitable external force in the immersion process.
Described active carbon reclaiming agent formula is as follows, all is weight percentage:
Sodium sulfate of polyethenoxy ether of fatty alcohol (AES): 15～25%
AEO (AE): 12～20%
Alkyl-carboxylic acid sodium sulphate (CAS): 0.1～1.5%
Sodium aluminosilicate: 0.3～2%
Polymerization of carboxylic acid salt (PCAS): 0.2～3%
Cellulose ether: 3～8%
Odium stearate: 5～10%
Natrium citricum: 8～15%
Sodium sulphate: 8～10%
Protease: 0.2～1%
Lipase: 0.5～3%
Deionized water: surplus
Method of the present invention has made full use of the catalytic action of enzyme, and the effect of matching surface activating agent, carrying out with the hydrolysis that quickens the adsorbed pollutant of active carbon, thereby make the adsorbed pollutant of active carbon change water-soluble material into by water-fast material, and, realized the regeneration of charcoal absorption activity with the water removing.
Usefulness of the present invention is: processing procedure is similar to traditional clothing washing mode, and the garment material that can become health care, clean skin for active carbon functional fabric has been created condition, is a kind of innovation of charcoal absorption activity regenerating method.
The specific embodiment
Below in conjunction with embodiment method of the present invention is further described.
Select castor oil, atoleine, lanolin for use, mix, make the mixing greasy dirt thus by 1: 1: 1 percentage by weight; Make emulsifying agent with phosphatide, phosphatide is 2: 1 with the described percentage by weight that mixes greasy dirt, makes the simulation greasy dirt thus, and active carbon functional fabric is carried out artificial pollution.
Get 4 500 * 500mm
2Active carbon functional fabric as sample.
Sample 1: directly be active carbon functional fabric, without any processing.
Sample 2: adopt above-mentioned simulation greasy dirt that this sample is carried out artificial pollution, but without other processing.
Sample 3: adopt above-mentioned simulation greasy dirt that this sample is carried out artificial pollution, with " it is clear " board washing powder of buying from the market the sample after polluting is handled, handle water temperature and also be 35～50 ℃, soak time is 45～60min also, stirs with suitable external force equally in the immersion process.
Sample 4: adopt above-mentioned simulation greasy dirt that this sample is carried out artificial pollution, the sample after polluting is handled with method of the present invention.
The size of active carbon functional fabric adsorption activity is characterized by the adsorption rate of active carbon functional fabric to ammonia and benzene.Experimental result such as following table:
| Pollutant | Washing agent or regenerative agent | Ammonia adsorption rate % | Benzene adsorption rate % | |
| Sample 1 | Do not have | Do not have | 85 | 5.7 |
| Sample 2 | The simulation greasy dirt | Do not have | 10 | 0 |
| Sample 3 | The simulation greasy dirt | Washing powder (it is clear) | 75 | 5.2 |
| Sample 4 | The simulation greasy dirt | Regenerative agent | 82 | 5.6 |
Above experimental result shows, method of the present invention and regenerative agent thereof, greasy dirt to active carbon functional fabric absorption has good effect of removing, can solve effectively active carbon functional fabric is made clothes, after particularly making underwear, people are adsorbed various mixing greasy dirts such as human secretion and reached capacity when wearing after, make the capable of regeneration problem of its adsorption activity, the garment material that can become health care, clean skin for active carbon functional fabric has been created condition.
