Textile dyes and finishes checklist: preproduction

What to take away

Use one checklist for one material, color, finish package, factory, and intended market.
Mark missing evidence as missing. Do not convert it to a pass.
Treat legal, safety, and unsupported-claim failures as stops, not low scores.
Test the final processed product after the care cycles relevant to the claim.
Reopen approval when a controlled variable changes.

This checklist is built for a preproduction gate. It creates a record that a second reviewer can follow. It does not certify a product or replace legal, chemical, laboratory, or mill expertise. Shoppers running a lighter version of the same exercise can use the store-level purchase checklist.

Header information

Record before review:

product and style number
color name and shade standard
fiber content and construction
fabric weight and finish package
mill, dyehouse, and finishing facility
production country and sales markets
intended user and skin contact
care route and expected cycles
claim text under consideration
reviewer, date, and document version

If any of these fields is unknown, the evidence may not describe the intended product. Definitions for the fields are in the overview of textile dyes and finishes.

Pass, review, or stop

Status	Meaning	Action
Pass	Current evidence matches the defined product and requirement	Record owner and approval date
Review	Evidence is incomplete, conditional, or near the limit	Assign a question, owner, and due date
Stop	Legal gate failed, identity is unknown, test failed, or claim is unsupported	Block approval until corrected and retested

1. Material and recipe identity

Fiber percentages and fabric construction are confirmed.
Preparation steps are listed.
Dye or pigment identity and supplier product are recorded.
Binder, carrier, fixing agent, softener, resin, coating, and other finishes are recorded.
Auxiliaries are included, not hidden under "processing chemicals."
Dosage or add-on ranges are controlled.
Approved substitutions require review before use.
Safety data and technical sheets are current.
Chemical lots can be traced to the production lot.
Screen, where relevant to the product and market, for PFAS, formaldehyde, azo colorants that can release restricted aromatic amines, APEO/NPEO, phthalates, and heavy metals; record use, test evidence, or the basis for exclusion.
For natural dyes, record the colorant source, extraction process, and mordants or other auxiliaries.
For enzyme or other biological treatments, record the preparation, carriers or preservatives, and inactivation or removal steps. For bio-based water repellents, identify the feedstock and the complete finish chemistry.

Stop if: the active treatment cannot be identified or the factory can substitute without review.

2. Legal and restricted-substance gate

Product category and destination markets are listed.
Applicable chemical restrictions are mapped.
Physical safety requirements affected by treatment are mapped.
Input screening and finished-product tests have distinct roles.
Laboratory reports identify the specimen and method.
Results are within the correct limit and still current.
Any failure has a closed corrective-action record.
For U.S. sales, assess applicable CPSIA requirements for children's products, including lead and phthalate requirements, and evaluate California Proposition 65 exposure and warning obligations.
For EU sales, check applicable restrictions in REACH Annex XVII. If the buyer or program uses the ZDHC Manufacturing Restricted Substances List (MRSL), screen manufacturing inputs against it; it is a voluntary list, not a law.
If OEKO-TEX STANDARD 100 is claimed or required, record the certificate and verify its product scope. Do not treat it as a substitute for legal compliance.
Confirm the testing laboratory's ISO/IEC 17025 accreditation scope when accreditation is required or specified.

Treating can change more than chemistry. The US Consumer Product Safety Commission's general apparel flammability standard is 16 CFR Part 1610; it classifies textiles by clothing flammability performance and prohibits the most dangerously flammable class for clothing. Determine the actual rule and exemptions for the product instead of applying one test to every category.

Legal and Restricted-Substance Gate

Product category and destination markets listed
Applicable chemical restrictions mapped
Physical safety requirements affected by treatment mapped
Input screening and finished-product tests have distinct roles
Laboratory reports identify specimen and method
Results within correct limit and still current
Any failure has closed corrective-action record

Stop if: a required report is absent, the sample is not the intended material, or a gate result fails.

3. Process control

Incoming fabric checks are defined.
Bath ratio or wet pickup is recorded.
pH, temperature, time, pressure, and cure limits are specified.
Wash-off and rinse endpoints are defined.
Shade measurement conditions and tolerance are specified.
Start, middle, and end-of-lot checks are planned where relevant.
Rework and shade-correction rules are documented.
Wastewater, air, sludge, and chemical-storage controls are assigned.

Record the actual approved recipe-specific ranges and control limits, with the measurement method and instrument where relevant; do not leave entries as "as standard." For instrumental shade approval, record the spectrophotometer setup and the color-difference calculation, such as ISO 105-J03. Set the product's acceptance tolerance in its specification rather than assuming a universal value.

Before production, run the approved trial on the defined substrate and record the recipe revision, equipment, bath ratio or wet pickup, pH, time, temperature, wash-off, shade measurement, and deviations. Compare results with the acceptance criteria set for this product. The dye and finish decision workflow provides workflow context; keep the trial record with this checklist.

Process Control

Incoming fabric checks defined
Bath ratio or wet pickup recorded
pH, temperature, time, pressure, cure limits specified
Wash-off and rinse endpoints defined
Shade measurement conditions and tolerance specified
Start, middle, and end-of-lot checks planned
Rework and shade-correction rules documented

4. Color and appearance

Shade matches the approved standard under specified lighting.
Metamerism risk has been reviewed.
Side-to-center and roll-to-roll variation are within limit.
There are no unacceptable streaks, spots, barre, creases, or frosting.
Print registration and coverage meet the design.
Dry and wet rubbing results meet the use case.
Wash, perspiration, water, and light tests match expected exposure.
Adjacent light materials and trims were checked for staining.

Select methods that match the product, exposure, and buyer specification, and record the method and edition used. Examples include AATCC 8 for crocking, AATCC 61 for laundering, AATCC 15 for perspiration, AATCC 107 for water, and AATCC 16 for light. These methods are not interchangeable and do not set product-specific pass limits.

Stop if: visible transfer can damage another garment or the care instruction cannot control a known failure.

Color and Appearance

Metamerism risk reviewed
Side-to-center and roll-to-roll variation within limit
No unacceptable streaks, spots, barre, creases, frosting
Print registration and coverage meet design
Dry and wet rubbing results meet use case
Wash, perspiration, water, light tests match exposure

5. Finish function and durability

The claimed function has a named test method.
Acceptance limits were set before testing.
Initial performance passes.
Performance after stated care or use cycles passes.
Hand, breathability, absorbency, strength, and appearance remain acceptable.
Coating or lamination adhesion is tested where relevant.
Odor and storage transfer are checked.
The test report covers the final finish package, not one ingredient.

For water-repellent finishes, AATCC 22 is a spray test for water repellency; AATCC 127 measures water resistance by hydrostatic pressure. Choose the method that matches the claim: spray repellency does not establish waterproofness.

Review if: the initial result passes but no durability result exists.

Finish Function and Durability

Claimed function has named test method
Acceptance limits set before testing
Initial performance passes
Performance after stated care or use cycles passes
Hand, breathability, absorbency, strength, appearance acceptable
Coating or lamination adhesion tested where relevant
Test report covers final finish package, not one ingredient

6. Care label support

Washing or dry-cleaning direction is supported by reliable evidence.
Water temperature, bleach, drying, and ironing instructions are complete.
Warnings address known color or finish damage.
Decorative parts, thread, lining, coating, and trims tolerate the direction.
The tested garment matches production.

For care-related testing, AATCC 135 addresses dimensional changes after home laundering, and ISO 6330 specifies domestic washing and drying procedures for textile testing. Record the selected procedure and the care conditions used; set any required cycle count in the product specification.

The Federal Trade Commission's Care Labeling Rule text, 16 CFR Part 423, requires regular-care instructions for covered apparel and gives colorfastness warnings as examples. It also describes reliable evidence based on testing or reasonable support. Use the current rule and qualified counsel for the actual product.

Stop if: every available cleaning method damages the product and the required warning is missing.

7. Claims and customer copy

Every claim names the property being discussed.
Test conditions and durability are stated when material.
"Natural" is not used as a safety conclusion.
"Non-toxic" or "chemical free" is removed unless a precise, lawful meaning is supported.
Antimicrobial wording matches the permitted claim scope.
Water-repellent wording is not upgraded to waterproof.
Certification scope matches the material, facility, or product named.
No supplier evidence is presented as independent product proof.
If a claim relies on certification, name the scheme and verify the certificate's scope and current status. GOTS, GRS, OEKO-TEX STANDARD 100, and bluesign have distinct scopes and are not interchangeable.
Do not treat bio-based or natural origin alone as evidence of safer chemistry, biodegradability, or lower impact; state the claim boundary and document its supporting evidence.

8. Final approval record

Field / Entry

Approved recipe and revision

Reports and specimen IDs
Care label version
Approved claim text

Reopen review after a change in fiber source, fabric structure, shade depth, dye or finish supplier, recipe, factory, machine class, cure, care label, target market, or claim. A change on the fiber side calls for the natural fiber identity checks as well.

Common questions

Can a blank field count as not applicable?

No. Write "not applicable" and explain why. A blank field gives the next reviewer no evidence.

Does a lighter shade need the same review?

It needs a risk-based review. Shade depth can change dosage and performance, but other treatments and legal requirements still apply.

Should input and product reports be filed together?

Yes, but label their roles. Input screening does not prove production application, and product testing does not reveal every process control.

When is conditional approval acceptable?

Only when no stop gate is open, the remaining issue has a defined limit, owner, deadline, and release control.

Who signs the checklist?

Assign owners for design, technical, chemical, quality, legal, sourcing, and claims as the product risk requires. One signature should not imply expertise in every field.
