What happened
Heberlein, a Swiss supplier of air interlacing and air texturing jets for synthetic filament yarns, is deepening its engagement in the Chinese market. The company is promoting two DTY jet product families — the APh-series and APe-series — and has opened a service hub in Shengze City to bring technical support closer to customers.
Why this matters to mills
Compressed air is a significant operating cost for yarn producers. Heberlein positions its DTY jets on the basis of reduced compressed-air consumption without sacrificing yarn quality. The APh-series is reported to cut air use by up to 10% on a comparative specification such as PES dtex 330f96. The APe-series has shown reductions of up to 15% in tests. Heberlein states that the new jets typically pay for themselves within 18 months through lower operating costs.
Product focus: Air Covering and interlacing
Air Covering is a primary application for Heberlein's DTY jets in China. The process uses controlled air jets to interlace an elastane core with a covering yarn at regular intervals. That produces integrated yarns that combine stretch, comfort and improved surface properties while remaining easy to process in knitting and weaving.
Heberlein highlights two performance points for the APh-series: higher knot stability or reduced compressed-air consumption depending on configuration. The APe-series also promises notable air savings while maintaining yarn quality.
Local service: Shengze City hub
Since August 2026 Heberlein has run a service hub in Shengze City. The facility is equipped to provide quick-response service visits, minor maintenance, and cleaning. Tools onsite include a portable air generator, an ultrasonic cleaning system, an airflow meter and an air splicer. These capabilities support practical onsite testing, troubleshooting and faster implementation of solutions during product trials.
Martin Zuercher, CEO at Heberlein, is quoted as saying the hub was opened to provide faster response times, stronger technical support and closer customer interaction.
Market approach and events
Practical implications for yarn producers
- Review current compressed-air consumption per machine and calculate potential savings if switching to APh or APe jets. Reported reductions are up to 10% (APh) and 15% (APe) in comparative tests.
- For Air Covering applications, test jet settings (air pressure, overfeed, elastane draft) against target downstream processing stability and fabric performance.
- Use the Shengze hub for rapid troubleshooting, onsite trials and short-turn maintenance to reduce downtime during pilot runs.
Bottom line
Heberlein's technical claims focus on reducing a key operating cost for spinners while keeping yarn performance intact. The local service hub is designed to speed adoption by shortening the feedback loop between trials, adjustments and production runs.
