1. Development of UV-curable finishing agents for textiles
This project’s major goals are as follows: 1) development of UV curable flame retardants(P and P/N classes); 2) development of UV curable waterproof breathable polyurethane coatings for high density PET fibers; 3) mass production of the newly developed UV curable materials. Throughout this study, the followings were accomplished: 1) synthetic technology of UV-curable flame retardants and waterproof breathable coatings; 2) formulation and packaging technology thereof; 3) low energy consumption and clean technology(60% of energy saving and zero emission of $CO_{2}$); 4) improvement of continuous production rate up to 300 min/m as well as 90% saving of facility area. In addition, it is believed that the newly developed UV curable fiber finishing agents, such as flame retardants and waterproof breathable coatings, will substitute the existing market and create a new market. Packaged merchandise will be supplied along with the UV curing machinery. The introduction of advanced low-energy based technology to the dyeing industry will contribute to international competitive power thanks to the increasing perception of the energy saving and environment friendliness by the industry.
2. Development of UV Finishing Machine
In this project, UV finishing machine for saving energy was developed. Traditional textile finishing processes require lots of energy to impart a function onto fabric because the process is wet processing, where water has to be usually evaporated. To reduce energy consumption, the finishing process must minimize water usage. To implement this kind of process, we designed a process that use ultra-violet light. So, we have developted a machine that can impart UV-curable resin onto fabric surface evenly and cure the resin with certain range of UV wavelength. To do this, we firstly developed pilot-scale machine to get preliminary data and skills. By using the data obtained during manufacturing the pilot machine, a commercial finishing machine equipped with gravure coater and UV curing lamp was successfully developed.
3. Development of UV-based Textile Finishing Technology for Energy Saving
This project’s final purposes are as follows: 1) UV coating of flame retardants for cotton/PET blends; 2) UV-based polyurethane coating of high-density PET fabrics for a breathable waterproof fabrics; 3) the performance improvement of water vapor permeability, hydrostatic pressure and laundering durability by optimizing formulation conditions(photoinitiator, resin and additives) as well as UV irradiation conditions(UV lamp and energy). Throughout this study, the followings were accomplished: 1) highly flame-resistant fabrics with a limited oxygen index(LOI) of 26 or more, smoke density of 100 or less, carbonized distance of 20 cm or less, and carbonized area of 30 $cm^{2}$ or less after 5 successive washing; 2) highly breathable waterproof fabrics with a moisture vapor permeability of 10,000g/$m^{2}$/24hr or higher and a hydrostatic resistance of above 5,000 mm$H_{2}O$; 3) low energy consumption and greenhouse gas generation : 77.7% energy saving and 70% reduction of carbon dioxide emission. In addition, it is believed that the newly developed UV-curable fabric coating technology can substitute the conventional wet-processed textile chemical finishes by substantial energy-saving and environmentally-friendliness without sacrificing high performances characteristics such as durable flame resistancy, water vapor permeability and hydrostatic pressure. The UV technology for highly functional textile coatings could be utilized for highly value-added textile products such as interior(sunblind fabric or curtain) and apparel goods. Moreover the introduction of the advanced technology to the dyeing industry will contribute to international competitiveness thanks to the ever-increasing perception of the energy saving and environment friendliness by the textile industry.
