Assessment of Chemical Fiber Air Filter for General Ventilation

Air filters for general ventilation have mainly been used to control the concentration of indoor particulate matter. In this study, the pressure differential, test dust capacity, quality factor and operating life of class F8 pleat–plate and multi-bag type chemical fiber filters were evaluated using an air filter performance test system. The results showed that the resistance increase rate of multi-bag filter (0.49 Pa/g·(cm/s)) was lower than that of pleat–plate filter (1.94 Pa/g·(cm/s)), the quality factor of the multi-bag filter was lower than that of pleat–plate filter, and the dust capacity of the multi-bag filter was much higher than that of the pleat–plate filter. The operating life of the multi-bag filter was 8 times as that of the pleat–plate filter with the measured PM2.5 of outdoor. The energy consumption of the pleat–plate filter was 2.2 times that of the multi-bag filter. Analyzing the electron microscope photos after dust loading, the dust depth of pleat–plate filter into filter material was thinner than that of multi-bag filter. The research results could provide data support for the design optimization and selection of ventilation filters and the treatment of the particulate matter in indoor environments.

Antibacterial Capability of Triclosan Treated on Filter Fiber Materials

Antibacterial filtration material is an effectively control technique of airborne biological pollutant to purify indoor air. This study aims to assess the antibacterial capability of triclosan treated on three filter fiber materials: the glass fiber (GF), the non-woven fabric (NF) and the chemical fiber (CF). Triclosan was loaded on filtration materials by the impregnation method. E. coli, S. albus and S. aureus were used as test strains. It’s found that the filter materials loaded with triclosan showed obvious antibacterial zone: the antibacterial zones against E. coli were 11.5 mm(GF), 13.2 mm(NF) and 11.0 mm(CF) respectively; zones against S. albus were 28.0 mm(GF), 21.0 mm(NF) and 25.0 mm(CF); zones against S. aureus were 21.5 mm(GF), 14.0 mm(NF) and 11.5 mm(CF). The percent reduction of bacteria of antibacterial fiber treated with triclosan against E. coli were 78.57% (CF) and 80.00% (GF), the percent reduction of bacteria of triclosan treated fiber against S. albus were 68.59% (NF) and 82.52% (CF), respectively. This research provided an effective antibacterial filter fiber material loaded with triclosan and it aids to reduce the transmission and harm of infectious diseases and to decontaminate the indoor environment.

Facial Synthesis of Adsorbent from Hemicelluloses for Cr(VI) Adsorption

It is challenging work to develop a low-cost, efficient, and environmentally friendly Cr(VI) adsorbent for waste water treatment. In this paper, we used hemicelluloses from chemical fiber factory waste as the raw material, and prepared two kinds of carbon materials by the green hydrothermal method as adsorbent for Cr(VI). The results showed that hemicelluloses hydrothermally treated with citric acid (HTC) presented spherical shapes, and hemicelluloses hydrothermally treated with ammonia solution (HTC-NH2) provided spongy structures. The adsorption capacity of the samples can be obtained by the Langmuir model, and the adsorption kinetics could be described by the pseudo-second-order model at pH 1.0. The maximum adsorption capacity of HTC-NH2 in the Langmuir model is 74.60 mg/g, much higher than that of HTC (61.25 mg/g). The green hydrothermal treatment of biomass with ammonia solution will provide a simple and feasible way to prepare adsorbent for Cr(VI) in waste water treatment.

Study on process of chemical fiber filament automatic doffing system based on simulation platform and machine learning

In recent years, a large number of automatic equipment has been introduced into the chemical fiber filament doffing production line, but the related research on the fully automatic production line technology is not yet mature. At present, it is difficult to collect data due to test costs and confidentiality. This paper proposes to develop a simulation platform for a chemical fiber filament doffing production line, which enables us to effectively obtain data and quantitatively study the relationship between the number of manual interventions and other process parameters of the production line. Considering that the parameter research is a multi-factor problem, an orthogonal test was designed by using SPSS software and was carried out by using a simulation platform. The multiple linear regression (MLR) and the neural network optimized by genetic algorithm were adopted to fit the relationship between the number of manual interventions and other parameters of the production line. The SPSS software was applied to obtain the standardized coefficients of the multiple linear regression fitting and the neural network mean impact value (MIV) algorithm was applied to obtain the magnitude and direction of the impact of different parameters on the number of manual interventions. The above results provide important reference for the design of similar new production lines and for the improvement of old production lines.

Design of an acrylic wastewater treatment method based on deep oxidation technology

Acrylic fiber is one of the earliest developed chemical fiber species in China. Acrylic products are fluffy, warm, soft to the touch, and have good weather resistance and anti-mildew and anti-moth properties. Acrylic fiber has a wide range of applicability, but the wastewater generated during its production is a major problem facing the world. The complex composition and high toxicity of acrylic wastewater pollutants, the presence of many oligomers and other difficult to biodegrade, as well as the presence of sulfate, sulfite and other bioinhibitory components, make the biochemical properties of acrylic wastewater very low, making it very difficult to treat. In this paper, we propose an acrylic wastewater treatment method based on deep oxidation technology to solve this problem, which can effectively carry out wastewater treatment and make it meet the national discharge standards.
