Rieter’s RSB-D 50c results in high-end airjet yarn

As a new player in the airjet yarn market, Rieter customer – Suzhou Sishon Biofibre Co Ltd – aims to become one of the largest producers in China. Despite increasing energy and personnel costs, the company’s goal is to market a yarn with a high level of quality and consistency.

Suzhou Sishon Biofibre Co Ltd is part of the Yingxiang Group and is located in Suzhou, China. The company processes cotton, viscose, polyester, and their blends.

The challenge
Sishon is a new player in the airjet yarn market and aims to become one of the largest producers in China.
Its air-jet yarn counts range from Ne 10 to 60. The goal is to achieve a yarn with an excellent reputation on the market for quality and consistency. However, rising costs for energy and personnel demand energy-saving solutions and automation in production. To achieve all these targets, Sishon needs to make careful decisions regarding its investment in equipment, especially in draw frames. The draw frame is the key factor in air-jet yarn production.

The solution
Sishon uses three draw frame passages. It decided to invest in 46 SB-D 22s draw frames and 52 RSB-D 50c draw frames. With the newest generation of autoleveler draw frame, the draw frame RSB-D 50c supports the customer in producing high-end yarn with consistent quality. The draw frame can processes several raw materials such as cotton, viscose, polyester, and their blends.

Benefits for Sishon
As the last draw frame passage, the RSB-D 50c runs perfectly with two passages of the prefixed SB-D 22s draw frame. The silver produced in this way directly feeds the next process stage. The system increases the production rate by 50 per cent and ensures a higher silver quality. In a workshop fitted with Rieter draw frames, three operators and two mechanics run 10 SB-D 22s and ten RSB-D 50cs. For the same production, they need five operators and three mechanics in a workshop with machines from other suppliers. Installing Rieter draw frames reduces the operator requirement by 40 per cent and the mechanic requirement by 35 per cent. RSB-D 50c draw frame guarantees smooth running of the air-jet spinning machine at highest efficiency and quality levels. The machine processes different raw materials with a yarn count ranging from Ne 10 to 60.

The customer’s statement
“The newest generation of the Rieter draw frame, the RSB-D 50c, runs perfectly with the prefixed SB-D 22s draw frame. This guarantees the highest quality and consistency of our air-jet yarns with lowest manufacturing costs,” says Shen Jiakang, General Manager, Suzhou Sishon Biofibre Co Ltd.
