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 industry of leading economic development brings larger destruction to the environment that people depend on for existence, the pollution of water resource brought as waste water, toxic emission and the broken hole of atmospheric ozone layer.Water is the existence basis of nature biotechnology, leaves water and just can not survive.And the destruction of ozone layer also causes harm ray can reach earth's surface more, wherein modal is exactly ultraviolet.
In the face of freshwater resources reality in short supply, how to utilize better and water conservation and how harmful ultraviolet being used, allow it be that people serve the focus becoming research.The annual water yield for domestic laundry of tool statistics China is probably 30 billion cubic meters, and this amount occupies 1/3 of domestic water total amount.If life textiles possesses self-cleaning function, as long as that just can make fabric light as new when washing through simple rinsing, water consumption is no more than 40% of the common washing of fabric.Estimate roughly with this, 18 billion cubic meters of can economizing on water every year.
The processing method making fabric have self-cleaning function at present mainly contains two kinds: one utilizes water and oil repellent agent to arrange fabric; Another kind utilizes catalysis material to arrange.There is certain environmental issue in the former, treatment process is comparative maturity also, and the latter exists, and catalytic efficiency is low waits series of problems.The method for sorting of a CN101709545A weaving face fabric, is characterized in that comprising the steps: 1. to get green compact cloth HEAT SETTING under 150 ~ 180 DEG C of conditions, wipe oil; 2. be washed to green compact cloth pH and keep 6 ~ 7, dry under 90 ~ 110 DEG C of conditions; 3. by the green compact cloth after drying through dressing liquid immersion liquid, containing 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 DEG C of conditions; 5. the fabric after step 4. middle oven dry is completed calendering under 180 ~ 220kg pressure, obtain the fabric after finished product arrangement.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, textiles is comprised the steps: to pad process in containing the maceration extract of self-cleaning finishing agent, pressure 2.5 ~ 3kg/cm2, liquid carrying rate 60 ~ 70%, by fabric constant temperature 0.5 ~ 2 hour between 115 ~ 150 DEG C after oven dry; Described self-cleaning finishing agent is made up of the component of following weight portion: nano titanium oxide 75 ~ 90 parts; Cationic surfactant 5 ~ 10 parts; Sodium polyacrylate disperant 0.2 ~ 1 part; 100 ~ 500 parts, water.Automatically cleaning textiles durability of the present invention is strong, has excellent self-cleaning function.Catalysis material is actually rare for weaving with the successful example of nonwoven material, and mainly how fastness problem, problem of aging, problem that photocatalysis efficiency low three large problem, particularly photocatalysis efficiency is not high, address these problems the focus becoming research.
