Poplin is a plain weave with a fine warp and a slightly heavier weft that gives a smooth, crisp surface; oxford is a basket weave in which two or more warp ends pass over a heavier weft, giving a soft and slightly textured fabric; twill is a diagonal weave with a visible wale that drapes and resists creasing better than plain weaves; and dobby is any fabric with small geometric patterns woven in by a dobby mechanism on the loom. The names describe the weave structure, not the fibre, so all four are made in cotton as well as in blends.
For a buyer, the weave determines the hand, the look, the weight range the mill can offer and often the dyeing route, so it should be the first line of the shirting specification.
Poplin and oxford
Poplin is the standard dress shirt fabric. The plain weave, with warp and weft interlacing one over one, gives a tight, flat surface that prints and dyes evenly and shows yarn quality clearly. It is usually piece-dyed or printed, and typically runs from about 100 to 130 grams per square metre in shirting counts. Its drawbacks are a tendency to crease and a stiffer hand in heavier weights.
Oxford uses a basket weave, most often two warp ends over one weft, with the weft usually heavier than the warp. The classic look comes from a dyed warp and a white weft, which gives a two-tone surface. Pinpoint oxford uses finer yarns for a smoother face, while royal oxford uses a more pronounced structure. Oxford is heavier, softer and more casual than poplin, and more forgiving of creases.
Twill and dobby
Twill interlaces warp and weft in a stepped pattern that produces a diagonal line across the fabric. The weave has fewer interlacings than plain weave, so yarns can be packed closer, giving a denser, heavier fabric with better drape and crease recovery. Shirting twills range from fine herringbone and cavalry twills to heavier brushed twills for winter shirts. The diagonal structure can show skew after washing, so it needs good finishing.
A dobby is not one weave but a family of small patterned weaves created by a dobby shedding mechanism that controls the warp in groups. Typical patterns include small diamonds, dots, stripes and textured grounds, usually tone on tone or white on white. Dobby fabrics can be based on poplin or twill grounds and are often used for premium shirts where a subtle texture is wanted without a print.
Choosing between them
- Formal and business shirts: poplin, pinpoint oxford or a fine dobby.
- Casual and weekend shirts: oxford, brushed twill or chambray.
- Easy-care programmes: poplin or twill in cotton and polyester blends.
- Premium and textured ranges: dobby on a fine poplin ground.
- Small first orders: piece-dyed poplin or twill, since yarn-dyed oxford carries a higher minimum order quantity (MOQ).
