Having installed three Saurer complete blowroom lines, 42 JSC 230 cards and ten BD 8 rotor spinning machines with 6,000 positions in 2023, Hengbang Zhifang is looking to further expand capacity this year with more BD machines, in order to meet the demand for its high quality recycled yarns.

The company, active in the textile industry for over forty years, is based in Lianyungang in Jiangsu, China, and currently has an annual capacity of 120,000 tons of yarn. It is part of the Hengbang Group which owns six major production facilities in China and Vietnam.

Hengbang Zhifang specialises in recycled yarns in counts ranging from Ne 6 to Ne 40 which are Global Recycling Standard (GRS) and Better Cotton Initiative (BCI) certified and suitable for a wide variety of textile applications. Global customers include both Nike and Uniqlo.

Because Hengbang obtains its raw materials from textile waste there can be significant variations in quality.

“ Every day the raw material is changing, because its never the same waste material which is delivered and Saurer BD rotor spinning machines were the first choice for us because they are flexible enough to cover all raw material deviations”, says the company’s president Li De. “It was also important to choose a rotor spinning machine that has a long history of spinning recycled material and Saurer specialists were on hand to help us to choose the right spinning elements, enabling us to run new materials on the BD 8 without a lot of trials, gaining high quality and at high speed.”

Saurer’s BD machines are equipped with numerous components specifically for dealing with recycled fibres, such as rotors with special grooves and coatings, special opening rollers and spinning navels.

The BD machines are also highly energy efficient, as a result of an energy-efficient main drive, the Twinsuction suction system and an impurity channel which reduces negative pressure by 40%. High quality bearings and leading rotor bearing technology also contribute to low energy consumption.
