3. High cotton with controlled stretch: 98.9% cotton preserves classic denim hand feel and breathability, with only 1.1% spadding for added comfort. Stretch is restrained so the fabric holds its shape without going soft and slouchy

二 Product Description

1. This is a high-cotton 3/1 twill slight stretch sulphur grey denim. It is directly dyed in grey via the sulphur dyeing process, which differs from the conventional approach of washing down blue denim to achieve grey. The grey shade is more accurate and stable, with natural, soft transitions after washing — an excellent choice for developing differentiated grey denim lines.
2. Composed of 98.9% cotton and 1.1% spandex, the fabric retains classic denim texture and breathability while providing moderate stretch for daily wear, without losing the structured hand feel denim is expected to have. Greige weight is 9.9 oz/yd² before washing, rising to approximately 11.5 oz/yd² after washing and shrinkage — a balanced weight that offers denim structure without feeling heavy. The finished width is 56-57 inches, and the 3/1Z right-hand twill produces a clear, uniform surface with clean grey warp-and-weft texture.
3. The low-saturation sulphur grey offers a premium, versatile look that works across jeans, jackets, work pants, shirts and skirts. It spans urban casual, minimalist business casual and vintage workwear aesthetics, suiting both men's and women's collections. Sulphur dyeing provides stable color fastness, with the grey softening naturally over wear and washes.
4. Washing instructions: Machine wash at room temperature, inside out. For the first wash, wash separately as sulphur dye releases excess color; do not mix with light-colored garments. Avoid high-heat drying to preserve the shape and grey shade. We support OEM and ODM customization. All goods undergo full-process quality inspection before shipment, and we provide professional technical guidance on cutting, sewing, washing and denim handling.
