Polyester and acrylic from the same plants that make our polyester feedstock: fibre-grade, film-grade and bottle-grade PET chip, polyester staple and filament, and acrylic staple, tow and top. Chip ships in 950–1100 kg bags, fibre in compressed bales — with the specification sheet and COA issued per lot.
Chip is specified mainly by intrinsic viscosity: 0.675 dL/g for fibre, 0.645 for film, 0.800 for bottle. Dullness is set by TiO2 content — semi-dull, full-dull and bright grades spin and dye differently, and the choice decides the lustre and depth of shade in the finished fabric.

| Bottle grade | IV 0.800±0.020 dL/g | 950 / 1050 / 1100kg bag | Water, carbonated soft-drink, edible-oil and hot-fill bottles |

| Wool type, 3.33 dtex × 90mm | Wool-system cut length; crimp and cohesion set per grade | Compressed bale | Woollen-spun yarns, knitwear, carpets and non-woven felt |
| Sewing thread and non-woven types | High tenacity low-shrink, or hydrophilic / flame-retardant variants | Compressed bale | Sewing thread, hygiene and geotextile non-wovens, filtration |
More than sixty staple specifications are produced. Elongation centre value is agreed between buyer and supplier within 25–40% and then held fixed; the specification sheet for your grade travels with the COA.
Textile filament in POY, FDY and DTY for draw-texturing, weaving and knitting, plus high-tenacity industrial yarn for tyre cord, hose, belt and geotextile.
| Grade | Typical specification | Packing | Typical applications |
|---|---|---|---|
| POY (partially oriented yarn) | dtex / filament count to order; semi-dull or bright | Palletised cartons / bales | Draw-texturing feed stock for DTY and ATY |
| FDY (fully drawn yarn) | dtex / filament count to order | Palletised cartons | Apparel, home textile and lining fabrics |
| DTY (draw-textured yarn) | dtex / filament count to order | Palletised cartons | Knitting and weaving yarns with bulk and stretch |
| Industrial yarn, bright | 1111–3333 dtex / 192f or 384f | Palletised cartons | Tyre cord, conveyor belt, geotextile, ropes and slings |
| Industrial yarn, low shrink | 1111 and 1667 dtex / 192f | Palletised cartons | Hose reinforcement, V-belt, canvas and tarpaulin |
| Industrial yarn, ultra-low shrink | 1111 dtex / 192f | Palletised cartons | Timing belts and dimensionally critical industrial fabrics |
Filament is quoted by dtex, filament count, dullness and shrinkage class. Denier tolerance, oil pick-up and shrinkage are stated on the specification sheet for each lot.
Polyacrylonitrile staple, tow and top: wool-like hand, light specific gravity, good dyeability and resistance to moths and mildew. Dry-spun fibre has a dog-bone cross-section, soft hand and high lustre; wet-spun covers the standard cotton and wool types.
| Grade | Typical specification | Packing | Typical applications |
|---|---|---|---|
| Acrylic staple, cotton type | 1.11–2.22 dtex, 38mm cut, bright or semi-dull | Bale 220–340kg | Knitted underwear, T-shirts, apparel fabric and blankets |
| Acrylic staple, wool type | 2.44–7.78 dtex, 51–113mm cut | Bale 220–340kg | Artificial cashmere, woollen knitwear, blankets and carpets |
