Weft Knitting TRIZ Cases

Embedded electrolytic copper nanoparticles in polymer fibers provide sustained antimicrobial protection that withstands repeated laundering cycles.

Combining elastomeric fibers with polyester bi-component filament reduces fabric shrinkage and edge curling while maintaining uniform surface appearance.

A leg garment uses an inwardly-wound helical support strip to compress the ventral ankle and instep for targeted swelling reduction.

Master-slave yarn feeding systems copy braking signals to reduce device complexity and operational costs.

Alternating stiff and flexible weft yarn bands in a warp knit sleeve resolve the trade-off between hoop strength and routing flexibility.

Knit spacer fabrics use high thermal shrinkage yarns to form void spaces, resolving limited compression resistance in seating and footwear.

Multi-bed knitting integrates distinct yarn types to resolve the trade-off between structural complexity and stretch resistance.

Continuous web construction forms multi-layer pelvic implants with tailored physical properties, eliminating time-consuming cutting and bonding steps.

A unitary knitted footwear upper integrates distinct functional zones through variable stitch patterns within a single continuous structure.

Segmented layers combine conductive fabrics, spacers, and perforations to overcome insufficient cooling in single-head-covering designs.

A double-knit fabric construction uses non-elastomeric-elastic yarns to maintain stretch and recovery properties without spandex.

A yarn feeding device uses a closed-loop control system to maintain constant tension and velocity.

Interknitted thermoplastic coated yarns form a porous mesh that resolves the trade-off between tear resistance and air permeability in footwear.

An inclined needle-holding unit with a non-cylindrical working surface reduces yarn tension and prevents breakage during high fineness knitting cycles.

Variable motor speed controlled by real-time tension feedback prevents exotic thread breaks and tangling while sustaining high knitting productivity rates.

Unitarily knitting resilient and conductive yarns eliminates moisture-induced layer detachment, ensuring stable skin contact.

Flattened guide channels in a seamless one-piece needle bed resolve hardening distortion while reducing weight, friction, and lubricant consumption.
