Recycled Polyester Yarn – GRS Certified 30D-300D

Recycled Polyester Yarn – GRS Certified 30D-300D

Recycled Polyester Yarn – GRS Certified 30D-300D

Choosing a recycled polyester yarn manufacturer is a documentation exercise before it is a price negotiation: the mill that owns the dyehouse controls the shade, and the mill that holds the certificate issues the paperwork behind your recycled content claim. DHOMA has spun and dyed polyester recycled yarn from 30D to 300D in Shantou since 1984, and also works as a recycled polyester yarn supplier for buyers who need 536 stock colours matched from an actual yarn-sample shade book and shipped without a dyeing queue. The framework below shows what to demand, what a trial order should test, and where the risk sits when a quote arrives from a trader instead of a maker.

Role and risk

Manufacturer, Supplier or Trader: Who Carries the Risk?

Three sellers can quote the same denier at three different prices. The difference is not the yarn on the quote — it is who owns the dyehouse, who signs the shade approval, and who is still answerable when a lot comes back off-shade.

Decision points to walk through before you compare prices, not after.
Decision point True manufacturer (in-house dyeing) Supplier / converter Trading desk
Who owns dyeing Its own dyehouse runs cone dye, hank dye and dope dye under one roof. Dyeing is booked into a third-party dyehouse. No dyeing at all; finished yarn is bought in.
Who controls shade In-house colour-matching team and equipment, with data colour analysis and evenness control across the same cone. Shade quality follows the outside dyehouse schedule and standards. Shade is whatever the source mill releases.
Who issues documentation Certification sits with the producing company, so recycled-content paperwork is first-hand. Documents are passed through and often lag the shipment. Documents are forwarded copies.
Who absorbs a defect claim The producer that dyed the lot. Responsibility is split between trader and dyehouse, which slows any claim. The claim is passed back up an unfamiliar chain.
Where lead-time risk sits In its own dyeing schedule and in whether your shade is already in the 536 stock colours. In a third-party dyehouse queue you cannot see. In allocation and freight, not in production you can audit.

Buyer framework

The 8-Point Supplier Qualification Checklist

Run these eight checks in order. Each one produces a written answer you can attach to the sourcing file, so the decision stops being an opinion.

1

Capacity and range

Confirm the denier band the mill actually runs on recycled polyester — DHOMA covers 30D to 300D — and whether it spins for apparel and labelling or for industrial use.

Ask for: current production range in writing.

2

Certification scope

Check that GRS certification is held by the producing company, not borrowed from a trading partner, and that it covers the exact yarn you are buying.

Ask for: certificate name and scope.

3

In-house dyeing

A mill with no dyehouse has less control over shade. Cone dye, hank dye and dope dye under one roof keep the approval loop inside one building.

Ask for: which dyeing methods run in-house.

4

Colour capability

Colour matching depends on equipment as much as on the operator. Data colour analysis plus shade-variation and same-cone evenness control is the baseline.

Ask for: the colour-matching workflow.

5

QC test list

Breakage strength and oil content should be tested before and after dyeing, not only on the raw yarn. Fastness tests cover colour, rubbing, sublimation and perspiration.

Ask for: the parameter list and acceptance values.

6

Stock colour programme

A ready-to-ship shade book removes dyeing lead time for repeat shades. DHOMA publishes 536 stock colours built from actual yarn samples.

Ask for: the current colour card or shade book.

7

MOQ and lead time

Both move with denier, luster, dyeing method and whether the shade is stocked or custom-dyed, so a single headline number is not enough.

Ask for: MOQ and lead time per spec, in writing.

8

Sample turnaround

The fastest way to score checks 1–7 is one paid trial order: a sample cone, a validation report and a delivery date you can measure.

Ask for: sample lead time before bulk.

Option Matrix: What You Choose and What to Confirm

This is the reference table for spec-driven buyers. Every option below is a current attribute of the product page — use the third column as the question you send back with your enquiry.

Parameter Options available Confirm when you order
Denier 30D to 300D State your target denier and where it sits in the range, plus the fabric or trim it feeds.
Twist Various twists available Give the twist direction and level your construction is built around.
Luster Semi dull, full dull, bright, FDY bright Match luster to the sheen your trim, label or fabric must show next to the finished garment.
Dyeing method Cone dye, hank dye, dope dye Ask which method fits your lot size and your shade-approval route.
Colour route 536 stock colours, plus custom dyeing and shade matching Say whether your shade comes from the stock book or needs to be developed.
Recycled content Recycled polyester, GRS certified Request the certification your end customer requires with the order.
Testing Breakage strength and oil content tested before and after dyeing Agree the acceptance values before bulk, not after the first lot lands.

Stock colours and dyeing

536 Stock Colours, Built From Real Yarn Samples

The fastest route through a qualification checklist is the one that skips the dyeing queue. DHOMA's colour shade book holds 536 stock colours, each made from actual yarn samples rather than printed swatches, and those shades are described as ready to ship.

When your shade is not in the book, the same dyehouse handles custom dyeing: cone dye for standard packages, hank dye for skein-form handling, and dope dye where the colour is built into the fibre route. One team and one set of colour-matching equipment sits behind both paths, which is why shade approval stays consistent between a stock reorder and a developed colour.

  • Stock route: pick the shade, confirm denier and luster, ship from the booked colour.
  • Custom route: send the target shade, agree luster and dye method, approve a dyed sample cone.
  • Either route: fix the acceptance values for breakage strength and oil content up front.

Decision router

Scenario to Specification: Pick Your Sourcing Path

Three buying situations cover most enquiries. Each one points to the specification decision that matters and the destination that settles it.

You need stock colours fast

Specification decision: take the shade from the 536-colour book and lock the denier inside 30D–300D plus the luster your finished trim already uses. Stock shades skip development and go straight to shipping.

See the stock colour option

You need custom dyeing or shade matching

Specification decision: send the target shade and decide between cone dye, hank dye and dope dye before you discuss price. Shade approval on a dyed sample cone is the gate between sample and bulk.

Start the trial order conversation

You need brand compliance documents

Specification decision: confirm the recycled-content certification first, then the compliance claim you intend to publish, then align the QC parameter list with what your brand auditor will ask to see.

Request the compliance details

Pre-PO process

From Spec to Bulk: A Four-Step Trial Order

A trial order is how the qualification checklist becomes evidence. Four steps, each with a deliverable you can sign off before the next one starts.

Step 01

Spec and colour card

Fix denier (30D–300D), twist, luster (semi dull, full dull, bright or FDY bright) and dyeing method, then choose a shade reference from the 536-colour book or send your target shade.

Step 02

Sample dyeing

Cone, hank or dope dyeing produces a sample cone for shade approval. Colour matching runs through the in-house team and equipment, with data colour analysis as the reference point.

Step 03

Fastness and strength validation

Breakage strength and oil content are tested before and after dyeing. Colour, rubbing, sublimation and perspiration fastness are checked so the shade survives finishing and wear.

Step 04

Bulk with documentation

Production runs through the four QC stages and the final parameters are re-checked: yarn count, breakage strength, oil content, cleanness, yarn shape, hairness, twist and evenness, with GRS paperwork for the recycled content.

What the trial order should prove

  • The shade you approve is the shade you receive in bulk, on the same dye method.
  • Breakage strength stays inside your acceptance value after dyeing.
  • Fastness results hold for the finishing process your product actually goes through.
  • The certification you need can be issued with the shipment, not chased afterwards.

Quality and compliance proof

Quality Control, Fastness Testing and Documentation

Compliance is not a document you attach at the end; it is the record of what was tested, when it was tested, and by whom. This is the control structure behind the recycled polyester yarn.

01

Colour precision

Data colour analysis drives shade matching, with strict control of shade variation and colour evenness within the same cone.

02

Before production

Raw material checking before the lot is released to dyeing, so an off-spec input never reaches the dyehouse.

03

During production

Strict testing at all phases of dyeing, which is where breakage strength and oil content are checked before and after the dye process.

04

After production

Thorough final checking of the finished cone before packing and dispatch.

Quality-checked GRS certified recycled polyester yarn cones ready for dispatch

Certification you can put in a compliance file

  • GRS certification for the recycled content of the yarn.
  • Stated compliance with the Oeko-Tex 100 Class I standard.
  • ISO 9001 held by the producing company.
  • A producer established in 1984 with over 40 years of spinning and dyeing experience.

Frequently Asked Questions

how do i tell a real recycled polyester yarn manufacturer from a trader?

ask four questions: where is the yarn dyed, which dyeing methods run in-house, who holds the certification, and who signs off a shade claim if a lot comes back off-shade. a maker answers all four with its own dyehouse and its own certificates; a trader answers them by forwarding an email.

what denier range and luster options are available?

the recycled polyester yarn is offered from 30d to 300d, with luster options of semi dull, full dull, bright and fdy bright, and various twists available. tell us the denier and luster your construction needs and we will confirm availability for that combination.

which dyeing methods can be used, and are stock colours really ready to ship?

cone dye, hank dye and dope dye are all available. alongside custom dyeing, dhoma maintains a colour shade book of 536 stock colours made from actual yarn samples, which is the faster route when your shade already exists in the book.

which quality parameters and fastness tests are checked?

tested parameters include yarn count, breakage strength, oil content, cleanness, yarn shape, hairness, twist and evenness, with breakage strength and oil content checked before and after dyeing. fastness testing covers colour, rubbing, sublimation and perspiration.

what are the moq and lead time?

both depend on the specification: denier within the 30d–300d range, the luster and twist you choose, the dyeing method, and whether your shade comes from the 536 stock colours or has to be developed. send the full specification when you request a quote and we will confirm moq and lead time in writing.

is the yarn certified, and can i get the documentation my brand requires?

the yarn is grs certified for its recycled content, the product page states compliance with the oeko-tex 100 class i standard, and the producing company holds iso 9001. dhoma has been manufacturing since 1984, so certification is issued by the mill that actually dyes your lot rather than passed down a supply chain.
