Abstract: The purpose of this paper is to introduce the application and Practice of a wet rubbing fastness improver DM-2589N in dark cotton fabrics. Methodology - The influence of DM-2589N mass concentration, baking temperature and time on the rubbing fastness are studied. The effects of DM-2589N on different fabrics, different dyes, and the effects of DM-2589N and other finishing agents in the same bath are studied. Findings - DM-2589N has excellent lifting effect on all kinds of cotton fabrics, and it is suitable for the improvement of rubbing fastness of fabrics dyed with reactive, direct, vulcanized and vat dyes. the optimum process is DM-2589N 40g/L, One dip and one rolling, baking temperature 150°C. Practical implications - The dry and wet rubbing fastness of the finish products can be increased above Grade 3-4, which can meet the first-class quality requirements of customers. Originality/value – The wet-rubbing fastness improver DM-2589N can be used in the same bath with the fixing agent and softener without adjusting the pH value, which can simplify the production process, shorten production time and greatly improve production efficiency.

Abstract: This research paper concerns the oil and gas well’s fires and the modern extinguishing process. We will introduce the fire thermal, chemical, and physical mechanisms on which our quenching mathematical model will be constructed based on the fire thermal parameters. The new technique involves the whole thermal sphere not only the fire visible core. Then the solution of the program was enhanced with the help of the international MATLAB program and was based on the available international fire data. Later the obtained solution shows very interesting results using the economic quenching matter and the process enhancement in optimum time. Practically we test the technique by building our own system and test it on three type of hydrocarbon fuels these are: 1- Kerosene, 2- Diesel, and 3- Benzene, the obtained results by adding clay to the sea water were very encouraging.
