Zetta Industries Co., Ltd. (CEO Won-dae Kim) announced that it has recently succeeded in developing an ultra-fine jet nozzle and a new jet head to innovate the jet head, which is the most essential part of the molten nanofiber production line.

In addition, it is said that the original patent application (Special No. 10-2021-94677) was completed without stopping at the simple development success. The company is strategically cooperating with Japan's Zetta Ltd, an innovative company in the nanofiber field, and attracts attention by localizing 100% of the mass production line using Zetta Spinning technology owned by Japan's Zeta.

The zetta injection technology was developed by researchers at Panasonic's Takahashi and Tokyo Institute of Technology Akihiko, who participated in the 'Advanced Functional New Structured Fiber-based Technology Development' project of NEDO (New Energy Industrial Technology Development Organization) in Japan in 2006 for 5 years. This is a new participle method developed by Professor Tanioka) after three years of follow-up research by establishing 'Zetta' in Japan in 2011 after completing a national project in Japan.

It has developed a zeta injection method that overcomes both the limitations of the existing ESD (Field Spinning) method and the Melt Blown method. is known.

​

Recently, Zeta Industries Co., Ltd. has succeeded in refining the more innovative spray nozzle to nano size. The ultra-fine nozzle and the new spraying device to which it is applied are expected to be applied in various ways, such as ▲ mass production of nanofiber that will revolutionize the textile industry ▲ secondary battery separator ▲ clean room filter ▲ air purification filter ▲ functional sound absorption/insulation material ▲ agricultural sheet ▲ eco-friendly packaging material.

​

When the ultra-fine nozzle is applied, it is expected to be helpful in high-tech industries in various fields such as ▲ semiconductor ▲ display process innovation ▲ secondary battery ▲ ESS separator efficient production ▲ 3D printer injection device ▲ recycled PET upcycling product production.

An official from Zeta Industries Co., Ltd. said, “We have established an initial production line in Chilgok, Gyeongbuk, and are exporting all of the filters for virus-specialized molecular masks to Japan. did. In addition, we signed a contract with Sungjin Industries (CEO Kim Hee-joong), which operates a large-scale sewing factory in Vietnam, and used an upcycled recycled PET membrane for clothing to produce winter padding to replace goose products in line with ESG management trends and vegan product preferences. entered,” he explained.

​

He said that the currently operating mass production line is capable of producing nanofibers on a daily scale of 0.5 ton with two lines. . This is interpreted as securing independent design and manufacturing capabilities of the equipment, such as localizing both the injection head and air heater, which are core parts, and attention is paid to the future.
