TL;DR: In this paper, a process for producing crimped polyester filament by winding the filament round heated roll and a device thereof is presented, which can produce natural crimp after that the woven fabric is treated with hot water.
Abstract: A process for producing crimped polyester filament by winding the filament round heated roll and a device thereof. The process comprising :the polyester filaments are spun from spinning nozzle(1) to split into two or more filament bundles(3), said splitted filament bundles wind separately round an electrically heated rotary roll (2) one or two turns, the bundles which are heated by electrically heated roll are combined into a yarn and wound into a cake(4). The yarn then is made into woven fabric. The polyester filaments or woven fabric can produce natural crimp after that the woven fabric is treated with hot water. By comparing with the art, the present process has reasonable design, simple device, the produced polyester filament and the woven fabric have natural crimp etc.

TL;DR: A fixed-biofilm carrier modified by mixing sponge iron (SI) and kapok fiber (KF) combined with strain Zoogloea sp. FY6 was constructed in this paper .
Abstract: In recent years, under the condition of lack of carbon source, the presence of composite micro-pollutants make the removal of nitrate seriously damaged, and to find a suitable way to solve this problem is imminent. A fixed-biofilm carrier modified by mixing sponge iron (SI) and kapok fiber (KF) combined with strain Zoogloea sp. FY6 was constructed in this study to get a fixed-biofilm reactor with merit denitrification performance. By adjusting the operation parameters, it can be concluded that when the carbon to nitrogen (C/N) ratio was 1.5, the hydraulic retention time (HRT) was 6.0 h, and the pH was 6.0, the nitrate removal efficiency (NRE) of the fixed-biofilm reactor was up to 95.4% (2.95 mg L-1 h-1). In addition, the fixed-biofilm reactor constructed in this study can remove lead (Pb2+) and tetracycline (TC) excellently in the presence of SI and Zoogloea sp. FY6, and the denitrification performance can still maintain a high level under the influence of different concentrations of Pb2+ and TC. Furthermore, the addition of SI not only removes the compound pollutants, but also protects the toxicity of the pollutant inflow in the bioreactor, and the metabolic process of microorganisms in the bioreactor also removes some of the compound pollutants. The high-throughput data showed the abundance of strain Zoogloea sp. FY6 was still the highest value under the influence of various pollutants, and the metagenomic prediction showed that the fixed-biofilm reactor had perfect denitrification process and iron redox cycle benefits. This study provides a valuable reference for sustainable utilization of natural biological resources and reduction of material costs in wastewater treatment plants (WWTPs).
