The special scouring agent used in the above examples 1-3 is EPA-98A scouring agent purchased from Kandex chemical Co., ltd. In Zhejiang, which is prepared by compounding sodium carbonate, sodium metasilicate, special isomeric alcohol polyoxyethylene ether and water, has the functions of permeation, cleaning and the like, and can effectively remove impurities such as oiling agents, stains and the like on textile fabrics.
The principle of removing or reducing pentachlorophenol in the above embodiment is as follows: pentachlorophenol is weakly acidic, and reacts with sodium carbonate or potassium carbonate to form soluble salts, and the soluble salts can be washed from fabrics by water, and the reaction equation is shown as follows:
sodium carbonate or potassium carbonate is weak acid and strong alkali salt, and the solution is alkaline by the hydrolysis of carbonate ions, so that the sodium carbonate or the potassium carbonate cannot be replaced by other soluble carbonates with the alkalinity weaker than that of the sodium carbonate or the potassium carbonate, and can not react with pentachlorophenol because the other soluble carbonates are with the alkalinity weaker, and in addition, strong alkali with the alkalinity stronger than that of the sodium carbonate or the potassium carbonate cannot be used, otherwise, the color of the fabric is destroyed.
The method comprises the steps of respectively carrying out chlorphenol removal treatment on a large red polyester-cotton knitted fabric, an orange polyester woven fabric, a brownish red polyester-viscose knitted fabric and a purplish red polyester-wool woven fabric according to the methods of examples 1-3, then detecting the content of pentachlorophenol on different woven fabrics before and after treatment according to GB/T18414.2-2006 method for measuring the chlorphenol content of textiles 2 nd part by gas chromatography, and the test results are shown in Table 1, so that the content of pentachlorophenol of samples which do not meet the requirements is obviously reduced or basically eliminated after the treatment by the method of the invention, and the method comprises the steps of using pentachlorophenol and Na 2 CO 3 、K 2 CO 3 The acid-base reaction of the polyester and the blended fabric thereof removes or greatly reduces the residual pentachlorophenol on the polyester and the blended fabric thereof, maintains the wearing performance of the polyester and the blended fabric thereof, in particular maintains the color and luster of the polyester and the blended fabric thereof, accords with the European Union on the residual polyester and the blended fabric thereofThe technical standard requirements of the remaining pentachlorophenol.
Table 1:
the foregoing description of the preferred embodiments of the invention is not intended to limit the invention to the precise form disclosed, and any such modifications, equivalents, and alternatives falling within the spirit and scope of the invention are intended to be included within the scope of the invention.
