In the 2011 Shijiazhuang Science and Technology Awards announced on August 1, three of the four special awards for science and technology were taken by chemical and pharmaceutical companies. Of the 83 scientific and technological progress awards, more than half were chemical and pharmaceutical companies. Chemical companies have become the protagonists of technological innovation in Shijiazhuang.
In recent years, the self-innovation awareness of chemical companies in Shijiazhuang City has gradually increased. Nearly 80% of small and medium-sized industrial enterprises have their own R&D institutions. Research investment has increased substantially, R&D has grown rapidly, and it has gradually become a new force in Shijiazhuang's economic construction.
Shijiazhuang Gongda Chemical Equipment Co., Ltd. completed the energy-saving environment-friendly ultra-large flow disc continuous drying device project, developed a highly efficient and energy-saving large-scale equipment design and manufacturing technology, stimulating new development vitality for the traditional equipment manufacturing industry. The device fills the gap in the domestic oversized flow tray drying device and has obtained two national patents.
Shijiazhuang Zhongqi Pharmaceutical Technology (Shijiazhuang) Co., Ltd. is a rising star in the field of Shijiazhuang biopharmaceuticals and has developed the world's first new drug that acts on multiple pathological processes in ischemic stroke, achieving the extraction from natural plants. The breakthrough in chemical synthesis has created a precedent for China's export of drug research and development technology to developed countries for the first time. The low molecular weight heparin calcium injection developed by Hebei Changshan Biochemical Pharmaceutical Co., Ltd. has made a breakthrough in the production technology of low molecular weight heparin calcium injection.

Weave Type:
1. Plain Weave: also called tabby weave, linen weav or taffeta weave, is
the most basic type of weaves. In plain weave, the warp and weft are aligned so
they form a simple criss-cross pattern. Each weft thread crosses the warp
threads by going over one, then under the next, and so on. The next weft thread
goes under the warp threads that its neighbor went over, and vice versa.
2. Twill Weave: In a twill weave, each weft or filling yarn floats across the warp yarns in a progression of interlaces to the right or left, forming a distinct diagonal line. This diagonal line is also known as a wale. A float is the portion of a yarn that crosses over two or more yarns from the opposite direction.
3. Plain Dutch Weave: similar with plain weave, just the weft and warp wire have different wire diameter and different mesh size.
4. Twill Dutch Weave: similar with twill weave, just the weft and warp wire have different wire diameter and different mesh size.
5. Reversed Dutch Weave: difference from standard Dutch weave lies in the thicker warp wires and less weft wires.
