Tissue forming fabrics operate under some of the most demanding conditions in papermaking: high machine speeds, low basis weights, and the critical requirement for superior sheet quality—softness, bulk, and strength—while maintaining energy efficiency and machine cleanliness. We have developed our own technologies to address these challenges. An optimal tissue forming fabric must balance fiber support, drainage capacity, dimensional stability, and wear resistance to meet the unique demands of tissue production.

Key Design Requirements

A. Sheet-Side Characteristics

· Ultra-fine yarn diameters (low-diameter weft and warp filaments on the paper side)

· Plain weave or very fine 2-shed paper side structure to obtain a smooth, low-marking surface

· High Fiber Support Index and support points for maximum mechanical retention

· Co-planar, homogeneous sheet-side topography for uniform formation and optimum sheet release

B. Drainage & Dewatering Performance

· Optimized flow resistance through controlled surface open area

· Defined dewatering channels for effective initial dewatering

· Low fabric caliper and low void volume to minimize water carryback

· High air permeability with fast drainage capability

C. Wear Side & Dimensional Stability

· Robust machine-side construction (e.g., 4-shed wear side) for excellent wear volume and life potential

· High cross-dimensional stability through increased number of binding points

· Resistance to high-pressure shower damage

· Reduced internal fabric wear for extended running life

D. Machine Cleanliness & Runnability

· Clean run with no water spray or fiber carryback at high tissue machine running speed

· Thin caliper design improves machine hygiene and reduces contamination

· Easy-to-clean surface for maintained permeability throughout fabric life

Customer Benefits

A. Superior Tissue Quality

· Improved formation and perfect fiber distribution

· Bulky, soft tissue base paper with high strength for downstream processing at high finishing speeds

· Excellent hand-feel and printability

B. Energy & Cost Savings

· High initial dewatering efficiency reduces drying energy

· Significant potential for savings in refining and vacuum energy

· Faster drainage enables increased machine speeds and production rates

C. Extended Fabric Life & Machine Efficiency

· Longer running life on the machine

· Reduced downtimes and fewer sheet breaks

· High process reliability and optimum life potential

D. Cleaner, More Reliable Operation

· No water/fiber carryback improves machine hygiene

· Consistent machine operating conditions throughout the entire running cycle

· Reduced need for cleaning and maintenance cycles

Summary

An optimal tissue forming fabric delivers superior sheet quality through fine, co-planar paper-side surfaces and high fiber support; energy efficiency through rapid dewatering and reduced drying, refining, and vacuum loads; extended service life through enhanced dimensional stability and reduced internal wear; and cleaner operation through low caliper, low void volume, and minimized water carryback. We would love to offer proven solutions for modern high-speed tissue machines, delivering measurable improvements in your productivity, quality, and total unit cost.
