Katsuragi Drill
Katsuragi Drill is generally a thick twill fabric woven at high density with relatively thick cotton yarn, and is a textile with durability and moderate firmness that is used for pants and workwear.

Definition and Overview
Katsuragi Drill is a relatively firm woven textile made with a twill weave that shows a diagonal twill line. Many types are made mainly from cotton, but depending on the application, polyester blends are also used. Thickness, firmness, and appearance vary greatly depending on yarn thickness, weave density, and finishing.
The name is a customary term referring to the fabric structure or a thick twill fabric, and it is not a standard name that uniformly defines composition, fabric weight, or density. When planning or ordering, it is important to check not only the name drill but also the blend ratio and fabric specifications.
Features
The surface shows diagonal ridges unique to twill weave, and while it tends to feel softer than plain weave, it is a textile that can easily provide the firmness and durability expected of a thick fabric. Through processing such as garment wash, brushing, and pigment dyeing, its appearance can be adjusted from a rugged workwear look to a cleaner look.
Drill based mainly on cotton tends to absorb moisture easily, and its texture changes with repeated wear. However, stretchability is basically low, so for products that require ease of movement, it is necessary to choose a version using stretch yarn or a polyurethane blend specification.
Main Applications
Taking advantage of its durability and moderate thickness, it is used for pants, work pants, overalls, jackets, blousons, and skirts. It is also sometimes used for bags, aprons, uniforms, and interior accessories.
Because specifications range from lightweight to heavyweight, applications and season are judged by the fabric weight and finish. In general, it is suited to autumn and winter use and year-round casual or work applications, but if the specification is lightweight, it can also be adopted for spring and summer bottoms.
How to Choose and Handling Precautions
When selecting, check the composition, fabric weight, fabric width, thickness, stretch, and dyeing method. For bottoms, abrasion resistance and the appearance around seams are important, and for outerwear, firmness and how the silhouette comes out are also important. For dark colors, anticipate color transfer from friction and color fading during washing, and check the colorfastness.
Unsanforized cotton-based products may shrink and twist when washed or steamed. Before mass production, perform washing tests, and if necessary, straighten the grain or hot water treat the fabric before cutting. Because steps and overlaps become thicker in heavyweight fabrics, design the sewing specifications according to the fabric, including needle, thread, and presser pressure, while considering seam allowance overlaps.
- Check shrinkage rate and twisting before full production.
- For dark-colored items, be careful about friction against white or light-colored items, and color transfer when wet.
- For heavyweight specifications, check for needle breakage and skipped stitches in multilayer areas such as belt loops and pocket openings.
Differences from Similar Terms
Twill is the general term for a woven structure that creates diagonal ridges. Drill is the name for a thick fabric made using twill, and it does not mean the same thing as twill itself. Twill also broadly refers to twill fabrics and includes a wide range of fabrics from lightweight to heavyweight compared with drill.
Denim is also a durable twill fabric, but it is generally characterized by dyed warp yarns and white weft yarns, creating a color difference between the front and back. Drill is often dyed in an overall similar tone and does not necessarily assume the faded look of denim. Chino cloth refers mainly to twill fabrics for pants, and depending on the yarn, density, and finish, it may have a texture similar to drill.
Frequently Asked Questions
How is drill different from denim?
Both are durable fabrics using twill weave, but denim is generally made with dyed warp yarns and white weft yarns, and its defining feature is the color difference between the front and back. Drill is often dyed to look like a single color, and its appearance can be designed broadly depending on composition, yarn usage, and finishing. You cannot judge thickness or performance as equivalent based on the name alone.
Does drill shrink when washed?
Cotton-based drill may shrink when washed or dried. The amount of shrinkage varies depending on composition, weave density, dyeing and finishing, and whether shrink prevention processing has been applied. Because it affects product dimensions, it is necessary to check shrinkage rate and twisting under actual washing conditions before mass production and reflect the results in the pattern and sewing specifications.
What should be noted when sewing drill?
In thick drill, overlapping areas such as side seams, belts, and pocket openings become thick. Select a machine needle and thread suitable for the fabric, and adjust presser pressure and thread tension through test stitching. Check for seam puckering, skipped stitches, and needle breakage, and if necessary, step down seam allowances to reduce thickness.
