What is a textile factory?
A textile factory — more precisely a garment factory or CMT factory — is the facility where fabric is cut and sewn into finished clothing. This is distinct from a textile mill, which converts raw fiber into fabric. The factory is the final manufacturing step before a garment reaches the brand and then the consumer. Understanding what happens inside one helps explain supply chain transparency and what ethical sourcing claims actually mean.
Textile factory vs textile mill
The distinction is fundamental: a mill converts fiber to fabric; a factory converts fabric to garments. In the supply chain, a mill comes first — it receives raw cotton, wool, or linen and produces rolls of finished fabric. That fabric is then shipped to a garment factory (sometimes called a CMT factory, standing for Cut, Make, Trim), where it is cut according to garment patterns and sewn into finished clothing. Some facilities are vertically integrated and do both, but most supply chains involve separate mills and factories, often in different countries. A brand that traces its supply chain to "the factory" has traced one step; tracing to the mill and the fiber source is a more complete picture.
What happens inside a garment factory
Fabric arrives in rolls from the mill and is inspected for defects before production begins. Pattern cutting: the garment pattern pieces are laid out on the fabric and cut — often in multiple layers simultaneously to increase efficiency. Sewing and assembly: the cut pieces move to sewing lines where workers assemble the garment in sequential operations, each worker typically handling one or a few steps. Finishing: buttons, zippers, elastic, labels, and other trim are attached. Quality control happens at multiple points to catch defects before they reach the final product. Completed garments are pressed, tagged with hangtags and care labels, bagged or folded, and packed for shipping.
Types of factories
CMT (Cut, Make, Trim) is the most common arrangement for smaller brands: the brand supplies the fabric and patterns, and the factory supplies labor and machinery to produce the finished garment. The brand retains control of fabric sourcing and design but takes on the complexity of managing fabric procurement and shipping. FOB (Free On Board) factories source materials themselves and produce finished goods — the brand provides design specifications and receives finished product. Full-package production takes this further: the factory handles everything from fabric sourcing through final packaging and shipping, with the brand only providing design direction. Full-package suits brands that want simplicity over supply chain control.
How to evaluate a factory
Certifications provide a starting framework: SA8000 and WRAP cover labor standards through third-party audits; GOTS factory certification covers both chemical standards and social criteria for facilities processing organic fiber; OEKO-TEX STeP covers environmental and social performance across a facility. Audit reports from recognized bodies (Bureau Veritas, SGS, Intertek) indicate the factory has been independently reviewed. Sample quality — the first samples a factory produces before a production run — reveals a lot about the attention to detail and precision in their sewing operations. Visiting the factory is the most reliable evaluation, but it is not always practical for smaller brands or individual buyers.
The transparency gap
Most clothing brands do not disclose which factories make their products. The Fashion Transparency Index — an annual survey of major brands — consistently finds that the majority of large fashion companies do not publish their tier-one supplier lists (immediate factories), let alone tier-two (fabric mills) or tier-three (fiber producers). Brands that publish full factory lists — Patagonia, Eileen Fisher, and a handful of others — represent the standard the industry has not broadly adopted. The questions to ask any brand: do you know which factory made this garment, have you visited the factory, and are audit reports available? A brand that can answer yes to all three has done the basic work of supply chain accountability.
Frequently asked questions
What is the difference between a textile mill and a textile factory?
A textile mill converts raw fiber into fabric — spinning fiber into yarn, then weaving or knitting yarn into cloth. A textile factory (garment factory or CMT factory) takes that finished fabric and turns it into clothing. The mill makes the material; the factory makes the garment. These are separate facilities with different machinery, different workforces, and different supply chain roles. A brand that "knows its supply chain" knows both who made its fabric (the mill) and who cut and sewed the finished garment (the factory).
What does CMT mean in clothing manufacturing?
CMT stands for Cut, Make, Trim — the three core operations a garment factory performs. Cut: fabric is laid in multiple layers and cut according to the garment pattern. Make: the cut pieces are sewn together into the finished garment shape. Trim: finishing details are added — buttons, labels, hangtags, packaging. In a CMT arrangement, the clothing brand supplies the fabric and patterns; the factory supplies the labor and machinery to produce the finished garment. This is the most common factory arrangement for smaller brands. Larger brands or those wanting more control may work with FOB or full-package suppliers.
How do I find an ethical clothing factory?
Start with factory certifications: WRAP (Worldwide Responsible Accredited Production), SA8000 (Social Accountability International), and BSCI (Business Social Compliance Initiative) all involve third-party audits of labor conditions. GOTS certification at the factory level covers both chemical standards and social standards. Fair Trade certification covers worker wages and conditions. Certifications are a starting point, not a guarantee — audits have limitations and can be gamed. Brands that publish their factory names and allow independent verification are more transparent than those that only cite certifications. Industry directories like the Fair Factories Clearinghouse list audited facilities.
What certifications should a clothing factory have?
For labor standards: SA8000 is the most rigorous international social compliance standard, covering wages, working hours, child labor, and the right to organize. WRAP is widely used in the US market. BSCI is common in European supply chains. For chemical and environmental standards: GOTS factory certification covers chemical use in garment production and includes social criteria. OEKO-TEX STeP (Sustainable Textile and Leather Production) covers factories on environmental and social performance. The relevant certifications depend on what the brand is trying to verify and the market it sells into. No single certification covers everything.
Do clothing brands own their own factories?
Very few clothing brands own their own production facilities. Vertical integration — owning both design and manufacturing — was more common in earlier eras of the industry but became economically unattractive as production moved to lower-cost regions. Most brands, including large ones, contract production to independently owned factories, often in multiple countries. Some heritage brands maintain owned or closely controlled production, particularly in sectors where manufacturing expertise is a brand differentiator — Italian luxury goods, Japanese selvedge denim, American heritage workwear. Factory ownership is rare, but long-term exclusive relationships with specific factories can provide similar levels of quality control and transparency.
