Polyester–Lyocell Blend Sheet Fabric: B2B Guide to Blend Ratio, Printing & Care
Share
Short answer: A polyester–lyocell sheet fabric should be purchased as a documented blend, not as a vague “lyocell-like” material. Before approving bulk production, the buyer should confirm the exact fibre percentages, legal fibre names for the destination market, weave and finished mass, usable width, print route, colour standard, wash/dry procedure, dimensional change, pilling and colourfastness requirements. The blend ratio must come from product documentation or testing—it should never be inferred from touch, drape or a marketing name.
Nantong Oulai’s active FAB-0701 Custom Color Pattern Soft Polyester Lyocell Sheet Fabric is listed as a polyester–lyocell blend for bedding sets, duvet covers, pillowcases, sheets, pajamas, sleepwear and home textiles. The live record offers custom print, colour, width, weight, yarn count and packaging, with a 100-metre MOQ and a stated sampling window of 7–14 days. Bulk timing is confirmed according to specifications and order quantity. The product page does not state the polyester/lyocell percentages, so this article does not invent them.
Why must the exact blend ratio be confirmed?
“Polyester–lyocell blend” identifies two fibre families but does not tell a buyer whether the fabric is predominantly polyester, predominantly lyocell or close to an even blend. That percentage affects fibre-composition labels, purchasing comparisons and the interpretation of test results. It may also affect hand, drape, moisture management, drying behaviour, strength and pilling, but those outcomes depend on the complete yarn, weave and finishing system and should be verified on the actual fabric.
| Evidence | What it can establish | What it cannot establish alone |
|---|---|---|
| Supplier composition declaration | The contractual declared percentages | Independent analytical confirmation |
| Laboratory fibre analysis | Composition result for the identified submitted sample under a stated method | Automatic coverage of every later production lot |
| Approved hand sample | Appearance, hand and drape reference | Exact fibre percentages |
| Trade or brand name | Commercial identification when properly documented | Generic composition or authorization to use a third-party fibre brand |
ISO 1833-1:2020 sets out general principles for quantitative chemical analysis of textile fibre mixtures. The laboratory should select the appropriate method for the declared fibres and report the sample identity, method and result. Buyers should also check that the tested sample is traceable to the approved material and order; see Oulai’s textile test-report verification guide.
Can this fabric be called TENCEL™?
Not without supporting brand and supply-chain documentation. Lyocell is a generic fibre name; TENCEL™ is a Lenzing trademark used for qualifying branded fibres. The live FAB-0701 record reviewed for this article says “lyocell” and does not state TENCEL™. Therefore, specifications, labels and marketing should use the documented generic fibre name unless the relevant branded-fibre evidence and claim permissions are available.
What does EU fibre labelling require buyers to consider?
For products placed on the EU market, Regulation (EU) No 1007/2011 governs textile fibre names and related labelling and marking of fibre composition. A buyer should confirm the finished product’s composition wording, language presentation and any component-specific obligations with its compliance adviser. A fabric supplier’s description is a starting document, not a substitute for the finished-product label review.
How should printing and colour approval be organized?
FAB-0701 is offered with custom colours and patterns. A practical approval sequence is:
- Submit final artwork with scale, repeat dimensions, orientation and colour references.
- Agree the print method and whether the artwork is engineered or repeating.
- Confirm the colour standard and viewing conditions.
- Approve a strike-off or sample carrying a unique sample ID.
- Record acceptable pattern registration, outline clarity, penetration and face/back appearance.
- Test colour change and staining under the intended laundering method.
- Compare first bulk production against the sealed approval sample before full conversion.
Do not use “colourfast” as an absolute promise. ISO 105-C06:2010 provides methods for colour fastness to domestic and commercial laundering, but the buyer must still define the relevant procedure and required rating. Different destinations and product categories can require different care and performance criteria.
Which specifications matter for sheet and duvet-cover use?
| Specification | Why it matters | RFQ instruction |
|---|---|---|
| Exact fibre percentages | Supports comparison and composition labelling | State declared ratio and required verification evidence |
| Finished mass | Affects hand, opacity, yield and handling | State target and tolerance using an agreed method |
| Total and usable width | Controls cutting layout and seam planning | Specify both; do not buy on nominal width alone |
| Print repeat and direction | Affects matching and cutting loss | Provide repeat dimensions and one-way/two-way direction |
| Dimensional change | Affects finished sheet and cover size | Set warp/weft limits after the stated wash/dry cycle |
| Surface change | Blends can show pilling, fuzzing or matting differently | Agree method, cycle and acceptance grade |
| Care route | Links product design, testing and care label | Confirm washing, drying and ironing conditions before approval |
How should laundering and dimensional change be tested?
Choose a procedure that reflects the intended product and market. ISO 6330:2021 provides domestic washing and drying procedures for textile testing, and ISO 5077:2007 addresses dimensional change after washing and drying. The report should identify the programme, temperature, detergent, drying route and number of cycles, then state results by fabric direction.
If surface appearance is important, include pilling/fuzzing/matting evaluation under ISO 12945-2:2020 or another buyer-approved method. A method name is not a pass/fail limit: put the acceptance criterion in the purchase specification.
What should be included in the RFQ?
- Product reference: FAB-0701 or approved custom derivative.
- Composition: exact declared polyester and lyocell percentages; verification documents required.
- Naming: generic fibre names and any branded-fibre claim evidence.
- Construction: weave, yarn count system, finished mass and tolerances.
- Dimensions: total width, usable width and roll-length convention.
- Artwork: file, repeat, orientation, print method and colour references.
- Performance: laundering colourfastness, dimensional change and pilling/fuzzing/matting criteria.
- Care: intended wash/dry route and target care-label symbols.
- Approval: strike-off, hand sample, pre-production sample and first-bulk check.
- Commercial terms: quantity, packaging, destination and required date.
How does this differ from purchasing pure lyocell?
A blend specification has an additional composition variable. Buyers comparing FAB-0701 with a pure-lyocell option should normalize the exact composition, construction, mass, width, print route and test results rather than treating the word “lyocell” as proof that the fabrics will behave identically. Oulai’s lyocell bedding fabric buyer’s guide explains the separate questions involved in lyocell sourcing.
What can Nantong Oulai customize?
The live FAB-0701 listing offers custom print, colour, width, weight, yarn count and packaging. Nantong Oulai records a 100-metre MOQ and a 7–14-day sampling window for this product; bulk timing is project-specific. Any change in blend ratio, construction or finish should trigger a refreshed sample, specification and test review rather than being treated as a cosmetic change.
Frequently asked questions
What is the polyester-to-lyocell ratio of FAB-0701?
The live product record does not publish the percentages. Request the declared ratio in the quotation and specification, plus analytical verification when required.
Is lyocell automatically TENCEL™?
No. Lyocell is a generic fibre name; TENCEL™ is a trademark. Use the brand only when the relevant evidence and claim authorization support it.
Does adding polyester guarantee lower shrinkage?
No. Dimensional change depends on yarn, weave, finishing and laundering as well as fibre content. Test the actual fabric using the agreed wash/dry route.
Can the same specification cover sheets and pajamas?
Not safely by default. The applications share a base fabric but may need different hand, seam, fit, care and performance requirements. Approve the converted product for each end use.
Is the blend certified?
The live FAB-0701 record reviewed for this article does not state a product- or lot-specific certification. Company or supplier scope certificates do not automatically certify this product or order.
