[China Instrument Network Instrument Industry] On May 31, Shenzhen Water Group, China Telecom and Huawei Technologies Co., Ltd. signed the “Smart Water Strategic Cooperation Framework Agreement” in Shenzhen, and reached a consensus on jointly implementing smart water construction and the application of the Internet of Things industry. . This is a brand-new exploration of the new technology of the Internet of Things in the field of water affairs, creating a pilot for Shenzhen's “Internet + smart water” innovation. For ordinary citizens, starting in August, Shenzhen will implement intelligent remote meter reading for the first batch of water meters. The intelligent water billing and uploading system will replace the “copying water meter at home,” and the water fee will also be able to be easily accessed through the mobile phone APP or the Internet. Payment.

“At present, the Water Group has about 1.2 million local end-users in Shenzhen. By the end of the “Thirteenth Five-Year Plan” period, after the city’s meter reading rate exceeds 65%, local end users will reach more than 3 million.” Shenzhen Water Group People said that in the face of a drastic increase in the number of users in the future, Water Group will build an “Internet + smart water” model based on smart water meters, and use Huawei and Telecom’s leading edge in communications technology and communications to build smart water information. The system will further enhance urban water supply and drainage support capabilities.

Polyester Draw Texturing Yarn Cationic

Polyester Draw Texturing Yarn Cationic is a new type of polyester product which is spun by dimethyl isophthalate with SO3Na into polyester. Its appearance is no different from that of ordinary polyester yarn. However, the ionic modified polyester filament not only improves the color absorption of the fiber greatly, but also reduces the crystallinity and makes the dye molecules permeable easily. The fibers are easy to dye, the absorptivity is improved, and the water-absorbing is also improved. This kind of fibers can not only ensure cationic dyeability, but also increase the micropore of the fibers, and improve the dyeing rate, air permeability and moisture absorption of the fibers, the fabrics can be soft, air permeable, comfortable, antistatic and dyeable at room temperature and atmospheric pressure. Fabrics made of cationic yarn have the following characteristics when dyed with cationic dyestuff: 

1. Bright tone, good deep dyeing;  

2. High water-absorbing; 

3. Good fastness to sunlight and fading; 

4. Good stability in high temperature dyeing bath; 

5. Dye stability is high when pH value changes in dyeing bath.
