Jinshi plans sleepwear fabric and garment performance testing around your selected materials and complete product. A fabric can feel right in a swatch and behave differently after cutting, sewing, printing and washing. Reviewing the combination helps your team approve dimensions, appearance and component behavior on a consistent basis.

| What you need to decide | What we evaluate | What the result must identify |
|---|---|---|
| Will the approved size remain suitable after care? | Fabric dimensions and garment points of measure before and after the chosen wash/dry procedure | Specimen, direction or measurement point, procedure, cycles and actual change |
| Will color transfer or change? | Relevant washing, dry/wet rubbing and other colorfastness properties | Color, print/finish, method, staining or color-change result and criterion |
| Will the surface retain its intended appearance? | Pilling, fuzzing, abrasion or other selected surface effects | Fabric face, method, exposure, specimen state and assessment |
| Will connected parts retain their shape? | Main fabric, rib, binding, zipper tape, seams and elastic in the garment | Component versions, laundering conditions and visible or measured differences |
| Will the fastening and seams perform as specified? | Relevant strength, attachment and repeated-operation checks | Attachment construction, method, force or cycles and acceptance requirement |
| Can the claimed feature be supported? | The specific property proposed for the product | Test scope, conditions, result and the precise claim it can support |
Our team can work with agreed ISO, AATCC or other relevant methods. Method names need a number, version and procedure selection. For example, ISO 6330 covers domestic wash/dry procedures for textile testing; ISO 5077 addresses dimensional change. ISO 105-X12 addresses rubbing colorfastness, while ISO 12945-2 uses a modified Martindale method for surface pilling, fuzzing and matting.
Those method references do not create one universal pass mark for all sleepwear. The buyer standard and product requirement determine the acceptance criterion, specimen plan and relevant conditions. See the official method references below.
The following are candidate quality-plan requirements. They become order requirements only when matched to the selected product and complete test conditions.
| Candidate requirement | Conditions to agree |
|---|---|
| Fabric shrinkage no greater than 5% in each direction | Wash/dry procedure, cycles, conditioning and direction; record growth as well as shrinkage |
| Rubbing colorfastness grade at least 3–4 (3.5 on the gray scale) | Dry and wet results, staining assessment, specimen preparation and selected method |
| Pilling grade at least 3 | Chosen method, exposure/cycles, load and assessment conditions |
| Five wash/dry cycles for a selected development review | Actual care route, observation points and the garment/component versions being compared |
These are development starting points, not published test results for every product. In gray-scale reporting, 3–4 denotes the half-step grade 3.5; it is not an unspecified range from 3 to 4. AATCC explains the equivalent grade notation. Garment dimensions also need point-specific tolerances and fit review; a fabric shrinkage figure alone cannot approve the finished fit.
For a zipper sleeper, we review main fabric, zipper tape, rib and the finished front opening. If the front becomes wavy, we investigate differential dimensional change, sewing stretch, feeding and tension. Changing only the pattern may leave the underlying mismatch unresolved.
A two-piece set adds neckline and waistband behavior, twisting, top-to-bottom proportions and color compatibility. A layered sleep sack adds lining, filling distribution, seams and drying behavior. Test selection follows those structures rather than the fiber name alone.

Internal checks help screen materials, compare development options and locate problems quickly. Where a formal third-party result is required, we coordinate the relevant laboratory scope, sample quantity, method, timing and report details. The laboratory report remains tied to the submitted specimen.
Before a repeat order, a new dye lot, print, finish, trim or material source is reviewed against existing evidence. We decide what remains relevant and what needs additional validation, then update the approved references.
No. Softness and dimensional stability are separate development objectives. We evaluate the proposed finish and the dimensional-control route, then check the combined garment under the agreed care conditions.
Coverage depends on the test, material differences and applicable rules. Provide the color and print range early so the sample plan can address it explicitly.
No. It is a defined development observation plan. Mandatory testing and any additional buyer requirements remain separate items in the project plan.
We identify the specimen and affected component, assess material or process changes, and repeat the relevant check on the revised version before approving that requirement.
