Bast Fiber Processing Goes Full Automation: ANDRITZ’s End-to-End Line Accelerates Natural Fiber Industrialization

Natural fiber industrialization is leaving behind the fragmented 'outsourced-by-segment' model. ANDRITZ has launched an integrated bast fiber processing line covering decortication, degumming, opening, carding, and airlay/carding web forming. This end-to-end solution means what previously required multiple equipment vendors and months of commissioning can now be closed within a single supplier framework.

Public industry data shows global bast fiber output has grown at an average of 8% annually over the past five years, but equipment fragmentation remains the core bottleneck for capacity utilization. Jute, flax, and hemp differ significantly in fiber length, strength, and gum content. Traditionally, each fiber type required separate degumming tanks, openers, and carding machines, with material flow and parameter matching relying on manual experience. ANDRITZ’s integrated design interlocks the degumming section with the opening and carding stages, allowing continuous chemical or biological degumming followed directly by airlay or carded web formation. This theoretically cuts line setup time by over 40%.

Industry Impact

For bast fiber mills, the most direct value is lower technical barriers. In the past, a medium-sized mill needed to purchase decorticators, degumming lines, and carding/web-forming machines from at least three different suppliers, then solve material transfer and speed matching issues independently. ANDRITZ’s integrated design means all interfaces and process parameters are managed by one team, saving at least 30% of initial equipment integration costs.

More importantly, the inclusion of airlay and random carding technologies pushes bast fibers beyond traditional apparel and rope applications into industrial nonwovens. Airlay is suitable for short fibers, producing three-dimensionally oriented webs ideal for automotive acoustic/thermal insulation, filter pre-layers, and geotextile drainage layers. Random carding retains some fiber orientation, making it better for building waterproofing base fabrics that require longitudinal strength.

Global procurement trends show demand for natural fiber nonwovens growing faster than synthetics in Europe, the US, and Southeast Asia. The EU’s Sustainable Textiles Strategy requires at least 25% recycled or natural fiber content in textile products by 2030, directly driving bast fiber substitution in automotive, construction, and packaging. ANDRITZ’s integrated line hits this window precisely.

Practical Recommendations

For Buyers - Assess your raw material mix: jute and sisal are coarser, better for airlay; flax and hemp are finer and longer, better for random carding. Confirm the main fiber type before selecting the line. - Check degumming environmental compliance: chemical degumming generates high-COD wastewater; biological degumming is slightly more expensive but easier to get environmental approval. ANDRITZ supports both—choose based on local regulations. - Demand factory acceptance tests for the full line: while segmented equipment can be tested individually, an integrated line requires a full run test at the supplier’s site with material balance data for all stages.

For Exporters - Target Southeast Asia and South Asia: India and Bangladesh are the largest jute producers, and their governments promote jute use in nonwovens, offering tax breaks for imported equipment. - Bundle line with process packages: selling equipment alone yields thin margins. Partner with ANDRITZ or similar suppliers to offer turnkey services including degumming recipes, fiber blend ratios, and product physical testing to increase order value. - Leverage the EU Carbon Border Adjustment Mechanism: end products using natural fibers instead of synthetics may qualify for carbon tariff exemptions when exported to the EU. Provide carbon footprint reports to overseas customers to strengthen pricing power.
