Virgin & Recycled / Prepared for Spinning
Virgin & Recycled Polyester Tops
We manufacture virgin and recycled polyester tops as aligned long-staple sliver for worsted and semi-worsted spinning. We set the fiber-length profile, sliver evenness, color, finish and packing around your polyester yarn, wool-blend and knitting-yarn requirements.
What Are Polyester Tops?
Aligned sliver prepared for your spinning process.
We convert suitable polyester tow into long, discontinuous fibers while maintaining their alignment as a coherent sliver. The conversion route and subsequent preparation are set to produce the length distribution, evenness and handling behavior required for spinning.
We supply the prepared top for a mill’s gilling, blending and long-staple spinning processes. The resulting yarn can serve woven fabrics, machine knitwear and hand-knitting applications.
How Tops Are Made
Crush cutting or stretch breaking?
We choose the qualified conversion route for the specified grade and measure the resulting length diagram, sliver evenness and spinning performance.
Set the fiber-length diagram
In crush-cut conversion, tow filaments are cut while an aligned sliver is formed. We set the cutting conditions for the intended fiber-length diagram and yarn route.
Check the produced length diagram and sliver quality.Wool-type distribution
For a suitable grade, controlled stretch breaking produces a range of long fiber lengths rather than one fixed cut length.
We qualify the tow mechanics, settings and resulting length distribution.Ready for the mill
We control sliver alignment and evenness through the selected preparation steps and pack the approved top in the agreed bump or bobbin format.
Sliver count, neps, finish and packing are grade controls.Where the Yarn Goes
For worsted yarn, wool blends and knitwear.
We design the top around the spinning system and target yarn; the final use is confirmed in the yarn and fabric specification.
100% Polyester Worsted Yarn
Aligned long fibers for spinning yarns used in woven apparel and selected furnishing or technical fabrics.
Wool / Polyester Blends
Prepared polyester sliver can be blended with wool on a suitable long-staple spinning system. Length profile, finish, shade and shrinkage must fit the companion wool and yarn design.
Machine & Hand-Knitting Yarns
A mill can spin tops into yarn for knitwear, sweaters, scarves and hand-knitting. Fiber bulk and softness are evaluated in the finished yarn and knitted article.
Other Long-Staple Blends
Compatible acrylic, viscose or other prepared fibers may be considered for blended yarns after trials on the intended machinery.
Spinning input: our tops are prepared long-staple sliver. Yarn count, bulk, handle and fabric performance are qualified through the mill’s spinning and finishing trials.
Hand Feel & Performance
Engineer the yarn's handle from the fiber up.
A finer, softer result may call for suitable lower-denier fibers, controlled crimp, an appropriate surface finish and a uniform sliver. Bulk depends on the grade, crimp, possible differential-shrinkage design and the yarn or fabric construction. A soft raw top alone does not prove the final fabric's feel.
For wool blends we match the top's length distribution, shade, finish and shrinkage to the companion fiber. Touch, pilling, drape and recovery are then checked on spun yarn and finished fabric under agreed test conditions.
Top Specifications
Specify the sliver, not just its color.
These are starting points. We finalize the production grade through the approved sample and product-specific technical data sheet.
We confirm the combination of fineness, length profile, color, bulk and material origin in the approved sample, grade-specific TDS and quotation. Top linear density, packing dimensions and test methods are agreed for the order. For recycled grades, recycled content and supporting documents are confirmed for the relevant production lot.
Quality & Evidence
Make trial approval repeatable.
We set grade-specific acceptance criteria and document the produced lots against the agreed specification.
Agree the top
Specify fineness, length diagram, sliver count, shade, finish and packing.
Run a mill trial
Assess top handling, blend behavior, yarn count, appearance and pilling where relevant.
Track the lot
We record lot identity, sampling, inspection methods and the values agreed for repeat supply.
Check claims
For recycled grades, we confirm GRS certification scope and shipment records where applicable. We check OEKO-TEX® STANDARD 100 certificate scope for the specified top grade.
Start with Your Yarn
Tell us what your mill intends to spin.
Send the yarn count, wool or other blend ratio, target hand feel, preferred conversion route, fineness, length profile, color, top format, monthly volume and destination. We will define the tops grade and provide the corresponding sample and technical specification.
