Polyester TOPS bumps — raw white and black combed top sliver

Polyester TOPS

At clover®, we manufacture 100% polyester TOPS — combed top slivers for worsted and woollen spinning lines. Fibre is converted from tow into aligned sliver, then wound as bumps (cylindrical top packages) or bobbins ready for the card and gill box.

Standard fineness runs 1.5 D through 3 D with fibre length 88–102 mm — the specification band for apparel yarn, acrylic-replacement blends, and worsted spinning programmes.

Grades are supplied in raw white, optical white, black, and dope-dyed solid colours, in both solid and high-bulk types as your spinning sheet requires.

TOPS Specification Matrix

100% polyester TOPS are produced against agreed technical sheets — fineness, hauteur (fibre length), lustre, finish, and packing format.

Standard colours:

  • Raw White
  • Optical White
  • Black
  • Dope-dyed solid colours

Packing: bump (cylindrical top) or bobbin — export-ready for container programmes.

Technical tuning: shrinkage, elongation, tenacity, and color fastness set against your yarn and fabric end test.

Programmes support worsted spinning and acrylic-replacement yarn counts. Share your target yarn specification and we align fineness, bulk type, and mechanical properties accordingly.

Worsted-Ready Bump & Bobbin Packing

clover® supplies TOPS in the formats spinning mills run every day:

  • Bump packing — cylindrical top packages (raw white or black) for direct creel feed
  • Bobbin packing — precision-wound packages for high-speed lines
  • Aligned sliver — converted from tow with controlled neps and staple orientation

Lot COA covers fineness, average length, tenacity, and elongation so your gill box and spinning frame see repeatable input.

Mechanical & Colour Control

TOPS properties are tuned to your yarn end use — not a single generic grade:

  • Shrinkage & elongation — set for weaving, knitting, or high-bulk hand-feel targets
  • Color fastness — dope-dyed programmes matched to apparel and home textile test methods
  • Solid vs high bulk — distinct profiles for fine-count yarn or acrylic-replacement blends

Technical teams support trial bumps before full-container programmes.

Polyester yarn and fabric — TOPS spinning programmes

Combed Top · Spinning Discipline

Polyester TOPS is a spinning input — fineness, hauteur, and sliver evenness determine whether your yarn holds count and shade on the frame.

clover® controls tow conversion, combing, and bump winding so worsted lines receive stable top sliver with predictable shrinkage, elongation, and color fastness shipment after shipment.

From raw white 2 D × 88 mm bumps to dope-dyed 3 D × 102 mm programmes, we structure grades around your yarn specification — solid, high bulk, or acrylic-replacement counts.

Share your fineness, fibre length, and yarn target.

Send TOPS specification (denier, hauteur, colour, packing format), monthly volume band, and destination port — clover® responds with grade detail and trial bump options.
