Dyed Cotton Fabric Guide: Types, GSM, Shrinkage and Bulk Sourcing

<p><strong>Dyed cotton fabric is cotton material coloured after the fibre, yarn or fabric stage.</strong> For apparel buyers, “100% cotton” and a colour reference are not enough to approve bulk production. Fabric construction, yarn count, weight, dye method, shrinkage, colourfastness and finishing determine whether the final garment feels premium and performs consistently.</p>
<h2>What is dyed cotton fabric?</h2><p>Dyed cotton fabric is made by applying colour to cotton fibre, yarn, fabric or a completed garment. The stage of dyeing changes the appearance, minimum order quantity, lead time, price and shade-control risk.</p>
Өнгөжүүлэх арга	How it works	Typical advantages	Main risks
Fibre dyeing	Loose fibres are dyed before spinning	Rich colour blending and heather effects	Longer planning and larger commitments
Yarn dyeing	Yarn is dyed before weaving or knitting	Checks, stripes, chambray and colour patterns	Colour inventory and higher setup cost
Piece dyeing	Greige fabric is dyed after construction	Efficient solid colours and broad availability	Lot-to-lot shade variation
Garment dyeing	Finished garments are dyed	Washed appearance and flexible colour testing	Measurement change, uneven seams and trim compatibility
<h2>Common woven cotton constructions</h2><ul><li><strong>Poplin:</strong> smooth, light and crisp; commonly used for shirts, dresses and linings.</li><li><strong>Twill:</strong> diagonal structure with good durability and drape; used for trousers, jackets and uniforms.</li><li><strong>Canvas:</strong> heavier plain weave for structured garments, bags and workwear.</li><li><strong>Voile and lawn:</strong> lightweight constructions for summer blouses, dresses and layered products.</li><li><strong>Oxford:</strong> basket-like construction that gives shirts more texture and body.</li></ul>
<p>The fibre content does not identify the construction. Two fabrics can both be 100% cotton while behaving very differently during cutting, sewing and washing.</p>
<h2>How to choose cotton fabric GSM</h2><p>GSM means grams per square metre. It is a useful comparison point, but it does not independently predict opacity, durability or warmth because yarn size, density, weave and finishing also matter.</p>
Ойролцоогоор жин	Typical applications	Buyer checks
60–100gsm	Voile, linings, very light blouses	Opacity, seam slippage and tearing
100–150gsm	Shirts, dresses, skirts and light uniforms	Drape, shrinkage and colourfastness
150–220gsm	Trousers, overshirts and structured dresses	Bulk, abrasion and needle selection
220gsm+	Canvas products, workwear and jackets	Stiffness, seam thickness and wash change
<h3>Example: 110gsm woven dyed cotton</h3><p>The original product on this page was a 100% cotton, piece-dyed woven fabric around 110gsm and 143cm wide. That specification can suit lightweight dresses, skirts and shirts when opacity and seam strength meet the design requirements. For a coat or jacket, 110gsm would normally need support, layering or a deliberately lightweight construction.</p>
<h2>Shrinkage: the number buyers must specify</h2><p>Cotton absorbs moisture and can change dimensions after washing and drying. Do not accept “pre-shrunk” as a complete specification. State the test method, wash cycle, drying method, number of cycles and maximum allowed change in warp and weft directions.</p>
<ul><li>Test the actual production colour because dyeing and finishing can alter shrinkage.</li><li>Measure before and after conditioning under controlled conditions.</li><li>Allow the pattern team to adjust garment measurements only after stable test results exist.</li><li>Repeat testing when the mill, construction, colour process or finish changes.</li></ul>
<h2>Colourfastness and shade control</h2><p>A visually correct lab dip does not guarantee production performance. Choose tests according to garment use and destination market.</p>
<ul><li>Colourfastness to washing</li><li>Dry and wet rubbing</li><li>Perspiration</li><li>Water and sea water where relevant</li><li>Light exposure for outerwear or display-sensitive colours</li><li>Colour migration when contrasting panels or trims are used</li></ul>
<p>Approve colour under a specified light source and keep the approved standard. Bulk rolls should be grouped by dye lot, and cutting plans should avoid mixing visible panels from different shade groups.</p>

<h2>Frequently asked questions</h2><h3>Is dyed cotton breathable?</h3><p>Cotton can be breathable, but comfort depends on construction, density, weight and finish. A dense coated cotton behaves differently from lightweight untreated poplin.</p><h3>Does darker cotton shrink more?</h3><p>Colour alone is not a reliable predictor. Dye process, finishing, construction and laundering conditions affect dimensional change, so each production quality and colour should be tested.</p><h3>Is 110gsm cotton transparent?</h3><p>It can be, especially in pale colours or open constructions. Evaluate full-width fabric over the intended lining, undergarment or skin-tone standard before approval.</p><h3>What is the safest way to approve bulk colour?</h3><p>Approve a lab dip or strike-off under specified lighting, define a tolerance, then compare bulk dye lots against that standard and keep shade groups separate during cutting.</p>Нэг өнгийн 100%C хөвөн 110гсм <a href="/what-is-twill/">Нэхмэл</a> <a href="/yarn-dyed-fabric-polyester/">Будсан</a> <a href="/cotton-vs-nylon-sustainable-fashion-guide/">Хөвөн даавуу</a> Хатагтай охидын юбка даашинз
