Soluble weft yarns are dissolved after weaving so multiple pile loops merge into taller piles, improving absorbency and texture consistency.

Double-pile weaving and alkali dispersion create dense 3D microfiber leather with fine surface piles, strong wear resistance, and no toluene use.

Sliding tongues and recesses replace wear-prone hinge joints in a one-piece weaving gripper, improving alignment and lowering maintenance.

By reversing warp yarn order and threading pile yarn through a gap, this weaving approach forms secure carpet knots with less manual labor.

Shared figure warp allocation across paired warp systems preserves pattern variation while cutting yarn use, fabric weight, and weaving cost.

Separate, dynamic tension profiles adapt each warp-thread group during weaving, limiting tension peaks while preserving fabric quality.

A weaving method inserts pattern-weft yarns outside the backing fabric to create corded pile structures with varied color effects.

A pile loom start restriction device uses a reverse-rotation number system to manage weft removal during restarts.

A gripper tongue body fixed to a main body via brazing or laser welding enhances connection strength for sliding alignment.

A feed control device manages pile-warp thread tension to produce fabrics with multiple distinct pile heights on a single weaving machine.

Stepping motor with reduction gear drives backrest and breast beam to overcome low speed limits of eccentric cam systems.

Hinged cross beams absorb lateral frame deformations to minimize vibration transmission and extend component service life.

A knife carriage moves translationally within each pick to cut pile warp yarns in a double carpet weaving loom.

Segmented comb design resolves tuft position control versus retention trade-offs, reducing yarn wastage in carpet manufacturing.

Positioning scan lines beneath alignment protrusions blocks light leakage, raising aperture ratio without extra black matrix layers.

Supporting devices link yarn separating rollers to reduce tension on reed dents, preventing breakage and visual disturbances in wide pile fabrics.

Dead pile threads create an intermediary layer covering binding warp threads, resolving the contradiction between pattern versatility and surface smoothness.

Automated detection of problematic color changes in card designs prevents mixed contours and blurred patterns in face-to-face pile weaving.

A weaving method interlaces pile warp yarns around third weft yarns to create a dense fabric structure with clean backing.

Segmenting pile and flat weave portions resolves the contradiction between absorption capability and drying time while maintaining superior hand feel.

A terry weave fabric structure uses double weft insertion in primary sheds to form loops while shifting mass toward cheaper yarns.

A warp tensioner roll uses dual mechanical compensation to maintain constant pile yarn force.
