Abstract
The invention discloses a function-intensified self-cleaning material and a production method thereof. The finished product is obtained through the steps of base cloth pretreatment, light sensitive color-changing treatment, membrane protection treatment, self-cleaning treatment and setting. The color of the fabric provided by the invention can become deep in the corresponding color under sunlight irradiation or can become dark red or dark blue from white after the fabric is subjected to the photoinduction color-changing treatment. As a result, the function-intensified self-cleaning material is also capable of reducing harm on the human body due to ultraviolet rays in addition to the synergetic self-cleaning function.
Description
Technical field
The present invention relates to a kind of function intensified self-cleaning material and manufacture method.
Background technology
Society, economic develop rapidly, and the environment that the industry of leading economic development is depended on for existence to people brings larger destruction, the pollution of the water resource of bringing as waste water, toxic emission and the broken hole of atmospheric ozone layer.Water be nature biotechnology existence this, leaving water just can not be survived.And the destruction of ozone layer also causes harm ray can reach more earth's surface, wherein modal is exactly ultraviolet ray.
In the face of freshwater resources reality in short supply, how better utilization and water conservation and how the ultraviolet ray be harmful to is used, allow it be that people serve the focus that becomes research.The annual water yield for family's clothes washing of tool statistics China is probably 30 billion cubic meters, and this amount has occupied 1/3 of domestic water total amount.If life possesses self-cleaning function with textiles, that is as long as just can make fabric light as new through simple rinsing when washing, and water consumption is no more than 40% of the common washing of fabric.With this rough estimation, 18 billion cubic meters of can economizing on water every year.
The processing method that makes at present fabric have self-cleaning function mainly contains two kinds: a kind of is to utilize water and oil repellent agent to be arranged fabric; Another kind is to utilize catalysis material to be arranged.There is certain environmental issue in the former, and treatment process is comparative maturity also, and there is the low series of problems that waits of catalytic efficiency in the latter.The method for sorting of a CN101709545A weaving face fabric, is characterized in that comprising the steps: 1. getting green compact cloth HEAT SETTING under 150～180 ℃ of conditions, wipe oil; 2. be washed to green compact cloth pH and keep 6～7, dry under 90～110 ℃ of conditions; 3. the green compact cloth after drying, through the dressing liquid immersion liquid, contains soil-releasing finishing agent and anti-soil agent in dressing liquid; 4. get the fabric mangle after immersion liquid, keep liquid carrying rate more than 58%, then cure under 160～180 ℃ of conditions; 5. the fabric after step being dried in 4. completes calendering under 180～220kg pressure, obtains the fabric after finished product arranges.Compared with prior art, the goods of gained of the present invention have decontamination, all good advantages of soil resistance.
CN102851943A discloses a kind of method for sorting of automatically cleaning textiles, comprise the steps: textiles is padded to processing in containing the maceration extract of self-cleaning finishing agent, pressure 2.5～3kg/cm2, liquid carrying rate 60～70%, after oven dry by fabric constant temperature 0.5～2 hour between 115～150 ℃; Described self-cleaning finishing agent is comprised of the component of following weight portion: 75～90 parts of nano titanium oxides; 5～10 parts of cationic surfactants; 0.2～1 part of Sodium Polyacrylate dispersant; 100～500 parts, water.Automatically cleaning textiles durability of the present invention is strong, has good self-cleaning function.Catalysis material is actually rare for weaving with the successful example of nonwoven material, is mainly fastness problem, problem of aging, the low not high problem of three large problems, particularly photocatalysis efficiency of photocatalysis efficiency, how to address these problems the focus that becomes research.
