Fabric Construction
Durable textile structure characterized by diagonal ribs and high thread density. Garment manufacturers specify workwear twill for uniforms and protective clothing because of its resistance to abrasion and tearing. This construction typically utilizes a two up one down or a three up one down weave pattern.
Surface Texture
Visible diagonal lines on the face of the fabric result from the staggered interlacing of the warp and weft yarns. Higher twist yarns are often selected to enhance the definition of these ribs and to increase the longevity of the garment. The heavy nature of the weave provides a barrier against mechanical stress in industrial environments.
Performance Characteristic
Physical strength is the primary requirement for fabrics used in high stress applications. Laboratory tests measure the tensile and tear strength to confirm that the material meets the safety requirements for the intended use. Because the weave is tight, the fabric also offers good protection against wind and debris.
Finishing Application
Chemical treatments for oil or water resistance are more effective on the dense surface provided by this weave. A mill applies these finishes during the final stages of production to improve the utility of the material. The boundary of this performance is the weight of the fabric, as excessively heavy twills may restrict the movement of the wearer.
Robust construction is required for industrial apparel durability.
