Abstract
The invention discloses a method for finishing a silk fabric with a formaldehyde removal function. The silk fabric is endowed with the formaldehyde removal function by utilizing excellent characteristics of tea polyphenol, and the binding force between tea polyphenol and the silk fabric is improved by complexing tea polyphenol by virtue of rare earth. The method comprises the following steps: grinding tea powder into powder, dissolving the powder into a diluted ethanol solution, heating, filtering, extracting, and concentrating, thereby obtaining a tea polyphenol concentrated solution; and immersing the silk fabric into the solution containing tea polyphenol, performing functionalized finishing of tea polyphenol on the silk fabric, immersing the fabric into a rare-earth-containing solution, complexing tea polyphenol with rare earth to form stable substances inside and outside the silk fabric, and ultrasonically washing and drying, thereby obtaining the silk fabric with the formaldehyde removal function. The silk fabric obtained by the method is bright in color, has the formaldehyde removal function and ultraviolet-resistant and antibacterial performances and is an environment-friendly multifunctional silk fabric.
Description
Technical field:
The invention belongs to textile material technical field, particularly a kind of method for sorting with the silk fabric of function of removing formaldehyde.
Background technology:
Formaldehyde is volatile organic compounds, it is the toxic chemical of China's priority acccess control, the material such as wood-based plate, furniture, wallpaper and coating in new finishing family can volatilize formaldehyde under certain condition, often cause formaldehyde, and the release period of formaldehyde is very long, more than 10 years can be reached, therefore indoor formaldehyde concentration is reduced, improve IAQ, be that guarantee is healthy, improve the important channel of quality of the life.
Natural dye Tea Polyphenols, except having the feature of easily biological-degradable, ecological, environmental protective, also has uvioresistant, antibacterial, anti-oxidant, deodorizing except excellent properties such as formaldehyde.Tea Polyphenols is also known as tea tannin, mainly be extracted from the general name of polyphenol compound in Aqua Folium Camelliae sinensis, primarily of the large class material composition of catechin, flavonoids, phenolic acid class and anthocyan 4, wherein catechin compounds is the main component of Tea Polyphenols, comprises catechin, epicatechin, epigallocatechin, epicatechin gallate etc.
Silk is natural protein fibre, has excellent wearability, is usually used in high-grade fabric.Silk contains a large amount of amino, carboxyl, hydroxyl isopolarity and non-polar group, can with the combination of the phenolic hydroxyl group generation ionic bond of Tea Polyphenols and other molecular separating force, can be combined with cotton, fiber crops, viscose glue, silk, wool and polyamide fibre, carry out the dyeing of textiles and give textiles uvioresistant, antibacterial, deodorizing except performances such as formaldehyde.
Along with the development of tea polyphenol extract technology, the rising increasingly of Tea Polyphenols output, the price of Tea Polyphenols is accepted gradually, and natural environmental-protective and the functional health type textiles of Tea Polyphenols functionalization are more and more subject to liking of people.
Summary of the invention:
The object of this invention is to provide a kind of method for sorting with the silk fabric of function of removing formaldehyde, the method is arranged silk fabric by Tea Polyphenols, the Tea Polyphenols complexing of rare earth inside and outside silk fabric is utilized to become stable material, silk fabric after arrangement is in yellow, not only there is the function except formaldehyde, and there is the antibacterial performance of uvioresistant.
Object of the present invention is achieved through the following technical solutions:
There is a method for sorting for the silk fabric of function of removing formaldehyde, comprise the following steps:
(1) tea leaf powder is made Powdered, add in the ethanolic solution that concentration is 50-90% with the ratio of mass ratio 1:10-30, heat 50-60 DEG C of insulation 30-60min, after filtering and concentrating, obtain Tea Polyphenols concentrate;
(2) Tea Polyphenols concentrate is mixed with sodium dihydrogen phosphate-citric acid, regulate pH value, add surfactant, solution is mixed, obtain Tea Polyphenols except Formaldehyde Resin;
(3) silk fabric is immersed Tea Polyphenols except in Formaldehyde Resin, bath raio 1:40,50-80 DEG C of process 30-60min, takes out silk fabric, removes unnecessary Tea Polyphenols except Formaldehyde Resin;
(4) immersed by the silk fabric of step 3 in the solution of rare earth of 2-4g/L, add sodium bicarbonate and regulate pH value, 35-45 DEG C of process 15-30min, carries out complexing by Tea Polyphenols and rare earth, forms stable material inside and outside silk fabric;
(5) taken out by the silk fabric of step 4, surface conjunction material is loosely removed in ultrasonic process, and after washing, 20-30 DEG C of oven dry obtains the silk fabric with function of removing formaldehyde.
Preferred as technique scheme, the concentration of the Tea Polyphenols concentrate described in step (1) is 90-98%.
Preferred as technique scheme, the pH value described in step (2) is 5-6.
Preferred as technique scheme, the surfactant described in step (2) is peregal 0, and the mass ratio of Tea Polyphenols and peregal 0 is 50:2-3.
Preferred as technique scheme, step (2) and the Tea Polyphenols described in step (3) except the content of Tea Polyphenols in Formaldehyde Resin be 3-5%.
Preferred as technique scheme, the pH value described in step (4) is 7-8.
Preferred as technique scheme, the ultrasonic time described in step (4) is 1-2min.
Preferred as technique scheme, the washing described in step (4) is for soaping.
Preferred as technique scheme, the color with the silk fabric of function of removing formaldehyde described in step (5) is for yellow.
Beneficial effect of the present invention is: silk has the active functional group of number of chemical character, and itself has good absorbability to gas, and the elimination factor of silk fabric to gas of Tea Polyphenols process significantly improves, and the elimination factor of Tea Polyphenols consumption more atmospheric is higher.Tea Polyphenols well can be adsorbed in silk fabric under low temperature solutions of weak acidity, and therefore this method selects sodium dihydrogen phosphate-citric acid mixing to regulate pH value, the infringement of adjustment pH value reduction to silk fabric that can be gentle.By rare earth as medium, Tea Polyphenols and its complex reaction can be strengthened, make the combination of Tea Polyphenols and silk fabric more stable.Tea Polyphenols is also that a kind of natural dye can by silk fabric stained yellow, and rare earth is also a kind of additive of environmental protection, and therefore obtained silk fabric environmental protection is favourable to environmental and human health impacts.And Tea Polyphenols also has natural uvioresistant and anti-microbial property, silk fabric uvioresistant and anti-microbial property can be given.
