Textile Quality Control and Testing Process
Consistent quality is what keeps a long-term supply relationship working. This page is for brands, wholesalers, hotels and importers who want to understand how a textile manufacturer in Turkey controls quality before goods are shipped. It explains the checks DRU Textile carries out from raw material to packed cartons, how testing is arranged according to buyer requirements, and which certifications apply to materials and to our organisation.
Quality Managed from Yarn to Finished Product
With more than 60 years of experience in textile manufacturing, we see quality as the result of a controlled process rather than a single final check. From yarn and accessories to fabric and the finished product, each stage is managed in a controlled and transparent way.
Our aim is export-standard quality at the agreed target price, which we describe as accessible premium. Quality control is one of the eight steps of our production process, which runs from product brief, sourcing, sample and approval to production, quality control, packaging and export.
The reference for every check is the approved sample and the agreed specification. That is why measurements, colours, materials, labels and packing are fixed in writing before bulk production starts.
Quality Checkpoints Through Production
Checks are carried out at several points, so that issues are found and corrected early rather than at the end of the line.
- 1Raw material and fabric
Yarn and fabric are checked before cutting against the agreed specification, such as composition, weight (GSM), construction, width and visible defects.
- 2In-line production
During cutting, sewing and finishing, pieces are checked at intermediate stages so that a problem is corrected before it repeats across the order.
- 3Measurements
Finished products are measured against the size chart and the tolerances agreed with the buyer.
- 4Colour
Colour is compared with the approved standard, such as an approved sample or lab dip, and shade consistency is checked within the order.
- 5Stitching and workmanship
Seams, hems, embroidery, prints, trims and labels are checked for appearance, secure attachment and finishing quality.
- 6Final inspection
Before packing, finished goods are inspected against the approved sample and the order specification, using the sampling method agreed with the buyer.
- 7Packaging
Packing, labels, barcodes, carton contents and carton marks are checked against the order details before shipment.
Measurements and Colour: What to Agree Up Front
Many quality disagreements start with an unclear reference. Agreeing a few points before production keeps expectations aligned on both sides.
Measurement tolerances
Each size chart should include the measuring points and an acceptable tolerance for each one. Tolerances are typically tighter for small, visible measurements and wider for longer dimensions such as length or width; the values are agreed per project.
Colour standards
Colour is approved on a physical reference, such as a lab dip, a strike-off for prints or an approved fabric sample. Because the same shade can look different under shop lighting, daylight and warehouse lighting, colours are best assessed under consistent lighting conditions.
Testing According to Buyer Requirements
Testing requirements depend on the product, the end user and the destination market. Baby textiles, hotel linen and retail home textiles each tend to call for different checks.
Tests are arranged according to the buyer's requirements. Where a buyer works with a preferred testing laboratory or protocol, this can be discussed and built into the plan. The table below lists tests that are commonly requested in textiles, as general guidance.
| Test area | What it typically checks | Often requested for |
|---|---|---|
| Colour fastness to washing | Colour loss and staining after laundering | Coloured and printed products |
| Colour fastness to rubbing | Colour transfer under dry and wet rubbing | Dark shades and printed fabrics |
| Dimensional stability | Shrinkage or stretching after washing | Garments, bedding and towels |
| Fabric weight (GSM) | Weight per square metre against the specification | Towels, robes and knitted fabrics |
| Absorbency | How quickly water is taken up | Towels and bathrobes |
| Pilling resistance | Surface fuzzing and pills after abrasion | Knitted fabrics and blankets |
| Seam strength | How seams hold under tension | Garments, robes and sleepwear |
| Harmful substances | Restricted chemicals in materials | Baby and children's products |
Certifications: OEKO-TEX®, GOTS and ISO 9001
Where the product requires it, materials certified to OEKO-TEX® Standard 100 and GOTS are used. This is particularly relevant for baby textiles and organic cotton products, where buyers often ask for certified materials.
ISO 9001 is shown on our website among our certification logos. Certificate details, including scope and validity, are shared on request, so you can check them against your own supplier requirements.
In general terms, each standard covers a different area:
- OEKO-TEX® Standard 100: a certification for textiles tested for harmful substances, with criteria that depend on the intended use of the product
- GOTS (Global Organic Textile Standard): a standard for textiles made from organic fibres, covering environmental and social criteria along the supply chain
- ISO 9001: an international standard for quality management systems
Working Together on Quality
Quality is easier to manage when both sides agree on the reference early. Before production, we confirm the approved sample, size chart, tolerances, colour standard, labels and packing method with the buyer.
If you would like an independent inspection before shipment, carried out by your own team or an inspection company you appoint, this can be discussed and planned into the schedule. Inspection results and any corrective actions are shared transparently.
