Karl Mayer pitches TM Weft as woven-look alternative for fashion mills

Karl Mayer will present an upgraded TM Weft warp knitting machine and a new WovenLike fabric collection at ITMA Asia + CITME 2026 in Shanghai, running 20–24 November. The move targets mills producing woven-look fashion fabrics who want warp-knitting throughput.

The Obertshausen-based machinery maker developed the collection at its Textile Innovation Center in Germany. Its commercial claim is specific: warp knitting with weft insertion can deliver the appearance and hand of woven textiles while keeping warp knitting's production efficiency. WovenLike fabrics also offer ease of care, stretch comfort and crease resistance, according to the company.

Karl Mayer also claims environmental advantages over conventional weaving, citing reduced finishing requirements and less wastewater treatment. The claim carries no certification, measurement or third-party verification. Buyers evaluating it for sustainability positioning should treat it as a process argument, not a compliance-backed claim, until Karl Mayer publishes comparative data.

Which yarns does the TM Weft handle?

Two- and three-bar tricot machines can already produce WovenLike fabrics. Karl Mayer positions the TM Weft above them for difficult materials: effect yarns, linen and acetate fibres. That positioning matters for mills whose woven-look programmes involve yarns that standard tricot machines struggle to process.

The new collection splits into two ranges that bracket the machine's capability:

• Structured autumn/winter fabrics. One crêpe uses Lycra T400 fibre for stretch, movement and fit. Another runs metallic yarns through a delicate bouclé structure. A third applies a burnout technique to open partial areas in a dense surface, producing a floral design.
• Lightweight, flowing fabrics. These take crinkle chiffon as their reference, with crêpe-like textures, fluid drape and varying transparency. The lightest construction weighs 63 g/m². Karl Mayer names modest fashion and Muslim women's clothing as target applications — a concrete market segment, not a general apparel pitch.

Material choice drives handle. Acetate gives a subtle sheen and a cool, smooth touch. Viscose gives softer lustre and a more natural skin feel. A cotton-blend fabric with a clean linear stripe design rounds out the lightweight range.

What do the machine upgrades change?

Three technical changes accompany the collection. A new E 36 gauge enables finer fabrics, extending the machine into lighter, more sophisticated constructions. A new EL pattern drive speeds pattern development and adds flexibility in patterning. The yarn tension system now uses continuous regulation instead of conventional tension control, which Karl Mayer says simplifies operation and supports consistent fabric quality.

Note what the announcement does not include: no throughput figures, no pricing, no stated production speeds for the new gauge, and no named early adopters or running orders. The performance claims rest on Karl Mayer's own descriptions. Mills will need benchmark data against their existing weaving or tricot lines before committing capital.

The company frames the combined package as an efficient manufacturing solution for fashion fabrics needing complex yarn combinations, distinctive surface structures and design freedom. That is a positioning statement, not a verified result.

Where can buyers see it?

ITMA Asia + CITME 2026 runs at the National Exhibition and Convention Center in Shanghai. Karl Mayer exhibits in Hall 4.1, Stand C18, for warp knitting technologies, and Hall 3, Stand A24, for warp preparation. A complementary show at Karl Mayer (China) in Changzhou will run the upgraded TM Weft live — the practical test of the new gauge, EL drive and tension regulation under real conditions.

Technical specialists will be available at both venues to discuss fabric development, processes and commercial applications.

The sourcing decision this forces: mills supplying woven-look fashion fabrics — particularly modest-wear and lightweight summer programmes — should benchmark the upgraded TM Weft against weaving capacity before their next capital cycle, and demand quantitative finishing and wastewater data behind the environmental claim.
