Reactive Printed Cotton for Bed Linen & Sleepwear: Print Route, Strike-Off & Colourfastness Control
Share
Short answer: Reactive printed cotton for bed linen and sleepwear should be purchased as a defined fibre, construction, print route and colour-performance package—not from the words “reactive print” alone. Buyers should approve the exact artwork, repeat, colour standard and strike-off; confirm that the selected order uses the declared reactive-dye route; and state wash, rubbing and any light-fastness methods with buyer-approved limits.
Nantong Oulai Trading Co., Ltd.’s active FAB-0036 Reactive Printed Cotton Fabric for Bed Linen is listed as 100% cotton for bed linen, sleepwear and coordinated bedding. Its live record also lists custom printing and colour matching, a 100-metre MOQ, a typical 7–10-day lead time after specification and sample approval, and reference width and weight ranges of 150–250 cm and 100–140 gsm that must be confirmed by item. These are sourcing facts, not automatic proof of a particular colourfastness grade.
What does “reactive printed cotton” mean for a buyer?
CottonWorks explains that print-paste formulation depends on fibre content, colourant system and printing equipment. Reactive dyes are among the dye classes used for cellulosic fibres such as cotton. Pigments are different: they require a binder or resin system to affix the colourant to the surface. Therefore, “reactive print,” “pigment print” and “digital print” are not interchangeable descriptions.
The buyer should ask which term describes the colourant chemistry and which describes the application equipment. A digital printer, for example, can apply different ink systems; “digital” alone does not prove that the colourant is reactive. For FAB-0036, the live product record identifies reactive printing, but the production specification should still preserve the approved route for the selected colourway and lot.
Which live FAB-0036 facts can be used in an RFQ?
| Field | Live product record | What still needs confirmation |
|---|---|---|
| Product | FAB-0036, active | Use the SKU on artwork, sample, test and order records |
| Fibre | 100% cotton | Order-level composition evidence and destination-market label wording |
| Reactive printed, with custom printing and colour matching | Application equipment, artwork, repeat, colour standard and approved strike-off | |
| Reference range | 150–250 cm; 100–140 gsm | Selected finished width, usable width and GSM for the quotation |
| MOQ | 100 metres | Whether the MOQ applies per design, colour, width and construction |
| Timing | Typically 7–10 days after specification and sample approval | Reconfirm against the final quantity, artwork and approval route |
Why is a strike-off more important than a screen image?
A monitor cannot lock the interaction among substrate whiteness, fabric construction, colourant, pretreatment, fixation, washing-off and finishing. Approve a physical strike-off on the intended base fabric, not just a digital artwork file. The approval should identify the file version, scale, repeat, orientation, colour standard, substrate SKU, print route, date and approver.
Review the strike-off for line definition, colour registration, small-detail legibility, mottling, unprinted areas, edge quality and the face/reverse relationship. For repeat and component placement, use the separate Oulai guide on directional, non-directional and engineered prints. It addresses cutting direction and matching; this FAB-0036 article addresses the print-route and colour-evidence package.
What colourfastness evidence should buyers request?
| Buyer risk | Relevant method | What the RFQ must add |
|---|---|---|
| Colour loss or staining in laundering | ISO 105-C06 | Selected procedure, adjacent fabric, reporting scale and acceptance grade |
| Dry or wet colour transfer by rubbing | ISO 105-X12 | Dry/wet conditions, face tested, number of colourways and required grade |
| Exposure to light for sunlit products | ISO 105-B02 when relevant | End use, exposure and buyer-approved requirement |
| Finished-size change after care | ISO 6330 with ISO 5077 and ISO 3759 | Wash/dry procedure, cycles, directions and limit |
ISO methods describe how to test; they do not create one universal passing grade for all bed linen and sleepwear. Dark grounds, saturated colours, white motifs and direct-skin-contact garments may justify different risk priorities. The product page does not publish numerical results, so Nantong Oulai does not convert the listing into an unsupported performance claim.
How should bed linen and sleepwear specifications differ?
FAB-0036 is offered for both categories, but the same artwork does not require an identical construction. Bed linen specifications may prioritize finished width, repeat efficiency, component matching, seam appearance and dimensional change over large panels. Sleepwear may use another weight or width and should consider drape, seam design, rubbing at contact zones and the finished garment’s care route.
If a coordinated collection uses both, assign separate item codes and BOMs. Keep the visual standard common where desired, but approve each substrate and end product independently. A colour match across different weights or structures should be judged on physical submissions under agreed lighting, not by reusing one laboratory value.
What should buyers include in the FAB-0036 specification?
- Identity: FAB-0036, intended item and destination market.
- Material: 100% cotton plus required composition documentation.
- Construction: weave, yarn details, finished GSM, usable width and finish.
- Artwork: controlled file, colour references, repeat size, direction and registration points.
- Print route: reactive colourant system and agreed application method for the order.
- Approval sample: strike-off on the selected base, signed and version controlled.
- Testing: named wash, rubbing, dimensional-change and any light-fastness methods.
- Acceptance: buyer-defined grades, sampling, rounding, re-test and lot disposition.
- Commercial terms: confirm MOQ by colour/design and timing after all approvals.
For shade approval workflow and instrumental colour difference, see how to approve fabric colour for bulk production. Lab dips and strike-offs are related approval tools, but a solid-colour lab dip does not replace a printed strike-off with the full artwork.
Frequently asked questions
Does reactive printing guarantee good wash fastness?
No. Dye class alone does not prove a result. Substrate preparation, fixation, washing-off, colour depth and finishing matter, and the selected colourway must be tested to the agreed method and requirement.
Is reactive printing the same as digital printing?
No. “Reactive” describes the colourant system; “digital” describes an application technology. A digital system may use reactive inks, pigments or another chemistry suited to the substrate.
Can one strike-off approve all widths and weights?
Not automatically. If the base construction, width, weight or finishing route changes, confirm whether a new approval is required because appearance and performance can change.
Does the 100–140 gsm range mean every option is available at every width?
No. It is a live reference range. The selected GSM, finished width and usable width must be confirmed together for the quoted item.
Does the supplied SGS report prove FAB-0036 performance?
No. SGS report SL42604345449801TX applies only to its identified white woven cotton sample and reported tests. It cannot be generalized to FAB-0036, its printed colourways or future lots.
