| Fiber Composition | Fiber content must match the approved product specification and care label. | 100% cotton for a pure-cotton style, or the exact approved cotton blend percentage when applicable. | Review supplier documentation and perform laboratory fiber-composition testing on representative samples. | Pass: Result is within the applicable legal labeling tolerance and matches the approved specification. | Critical |
| Fabric Weight | Fabric weight should provide consistent comfort, opacity, and durability. | Typical wholesale target: 140–190 g/m² for lightweight cotton sleep shirts, unless otherwise specified. | Condition fabric samples and measure mass over a defined area using a calibrated textile balance. | Pass: Within ±5% of the approved target weight, with no significant panel-to-panel variation. | Major |
| Fabric Construction | Knitted fabric must have a stable structure with an even surface and suitable recovery. | Single jersey or another approved knit construction; no dropped stitches, holes, barre, thick-thin places, or excessive curling. | Inspect fabric under adequate lighting and examine both sides before garment assembly and after washing. | Pass: No visible structural defect in the body, neckline, sleeve, or hem areas. | Major |
| Color Consistency | Color must match the approved shade standard throughout the production lot. | Use an approved color swatch or instrumental color standard for each colorway. | Compare under standard daylight conditions and, where required, verify with a spectrophotometer. | Pass: No obvious shade variation between panels, sizes, or cartons; instrumental tolerance follows the approved standard. | Major |
| Colorfastness to Washing | Color should remain stable during normal laundering and must not stain adjacent light-colored fabrics excessively. | Recommended minimum: Grade 4 for color change and Grade 3–4 for staining, subject to the destination-market requirement. | Wash test samples using the specified care instructions and assess with a recognized gray scale. | Pass: Meets the approved test method and the stricter applicable market requirement. | Major |
| Dimensional Stability | Garment measurements must remain within tolerance after the stated care process. | Recommended target after washing: maximum ±5% length change and maximum ±5% width change unless a different tolerance is approved. | Measure key points before and after washing, including chest width, body length, sleeve length, and hem width. | Pass: All critical measurements remain within the approved tolerance chart. | Major |
| Size and Measurement Accuracy | Finished garments must conform to the wholesale size specification. | Recommended tolerance: ±1.0 cm for major measurements and ±0.5 cm for smaller detail measurements, unless otherwise specified. | Lay garments flat without stretching and measure with a calibrated flexible ruler or measuring table. | Pass: Sampled garments meet the approved measurement chart and size grading remains consistent. | Major |
| Seam Strength | Seams must withstand repeated wear, movement, and laundering without opening. | Side seams, shoulder seams, sleeve joins, and underarm areas should be securely stitched and properly reinforced. | Perform visual inspection, manual stress testing, and laboratory seam-strength testing when required by the purchase specification. | Pass: No seam opening, skipped stitching, excessive thread breakage, or seam slippage under the approved test load. | Major |
| Stitch Quality | Stitching must be even, secure, and appropriate for lightweight sleepwear. | Typical production target: approximately 10–12 stitches per 3 cm for standard lockstitch seams, or the approved construction requirement. | Check stitch density, skipped stitches, loose threads, puckering, uneven tension, and back-tacking at stress points. | Pass: No skipped stitches or open seams; loose threads are trimmed and stitch tension is balanced. | Major |
| Neckline and Hem Finish | Neckline, sleeve openings, and bottom hem must lie flat and remain comfortable against the skin. | Consistent seam allowance, even coverstitch or binding, smooth curves, and no exposed sharp edges or bulky joins. | Inspect the garment inside and outside, then check appearance after laundering and gentle stretching. | Pass: No twisting, roping, skipped stitches, raw edges, or unacceptable waviness. | Major |
| Print, Embroidery, and Decoration | Any decoration must be securely attached, accurately positioned, and free from harmful surface defects. | Artwork, placement, color, scale, and hand feel must match the approved sample; avoid rough or peeling surfaces in sleep-contact areas. | Compare with the approved artwork and perform adhesion, rubbing, and wash tests where applicable. | Pass: No cracking, peeling, migration, loose threads, distortion, or position error beyond the approved tolerance. | Major |
| Trims and Labels | Labels, threads, drawcords, and other trims must be safe, legible, and correctly placed. | Care, fiber-content, size, and country-of-origin information must be accurate and securely attached where legally required. | Verify label content against the order file and inspect attachment strength, position, and abrasion comfort. | Pass: Correct information, legible printing, secure attachment, and no sharp or irritating components. | Critical |
| Chemical and Product Safety | Materials and finished garments must comply with the destination market's chemical and safety requirements. | Screen for restricted substances such as prohibited azo dyes, excessive formaldehyde, heavy metals, and other regulated chemicals as applicable. | Review material declarations and use accredited laboratory testing based on the destination market and product risk assessment. | Pass: All required test results comply with applicable regulations and buyer-specific restricted-substance limits. | Critical |
| Odor and Cleanliness | Finished garments should be clean, dry, and free from abnormal chemical, mildew, oil, or storage odors. | No visible stains, foreign fibers, loose needles, insects, moisture damage, or unacceptable odor. | Conduct visual and odor inspection in a clean, well-ventilated inspection area. | Pass: Garments are commercially clean and suitable for direct consumer handling after normal packaging. | Major |
| Workmanship Defect Classification | Defects should be evaluated using an agreed sampling plan and defect classification. | Use a recognized sampling standard, such as ANSI/ASQ Z1.4, with buyer-approved AQL levels. | Inspect randomly selected cartons and classify defects as critical, major, or minor according to the inspection manual. | Pass: No critical defects; major and minor defects remain within the agreed AQL limits. | Critical |
| Packaging and Carton Marking | Packaging must protect garments from moisture, contamination, compression, and size-mixing during transport. | Use correct folding, individual packaging where required, carton count, assortment, carton dimensions, and shipping marks. | Check packaging materials, carton strength, barcode or shipping information, assortment accuracy, and carton weight. | Pass: Cartons are intact, correctly marked, dry, and consistent with the approved packing list. | Major |
| Final Appearance | The sleep shirt should present a clean, comfortable, commercially acceptable appearance. | Body must be symmetrical; panels must align; fabric must be free of noticeable defects; garment must be properly pressed or steamed. | Inspect garments on a flat surface and, for selected sizes, on a mannequin or fitting form under standard lighting. | Pass: No obvious defect is visible at normal viewing distance, and the garment matches the approved reference sample. | Major |
