Roll

Definition and Overview

A roll is one unit of textile bundled in a rolled or folded state. In woven goods, it is also called a bolt, and it is used for ordering and supplying textile, inventory management, and cutting plans. For knits and nonwovens, it may also be called a roll or a bolt.

The length per roll varies depending on the type of textile, specifications, and manufacturer. For that reason, it is important not to judge the required fabric consumption from the label “one roll” alone, but to check the actual roll length and textile width.

Features in Trading and Cutting

Textile may be sold cut by the meter or sold by the roll. Buying by the roll helps secure a stable amount of material for mass production, but the length that can actually be used may be affected by the textile ends and the inspection results.

If the production period or dyeing conditions differ from roll to roll, differences may occur in color tone, texture, width, and shrinkage. Even when producing additional quantities under the same product number, it is common to secure the required amount together while considering lot differences.

• At the time of ordering, check the roll length, width, quantity, and whether cutting is allowed.
• Before cutting, check the face and back, grain direction, and selvage condition of the roll.
• During inspection, check textile defects such as stains, weaving flaws, and uneven color.

Points to Consider When Choosing and Handling

The required number of rolls should be calculated not only from the fabric consumption per garment, but also with allowances for pattern matching, grain direction, cutting loss, shrinkage, and any portions that may be excluded during inspection. Patterned materials, fuzzy materials, and directional materials especially require extra margin in planning.

During storage, protect the rolls from dirt, direct sunlight, and humidity, and manage them in a condition that is less likely to deform. If they are left in the same position for a long time, curl marks or fold lines may remain, so consider the storage method according to the characteristics of the material. For products involving washing or processing, also check the shrinkage rate in advance.

Differences from Similar Terms

A roll refers to the amount or packaging form of bundled textile, and is not a specification that indicates the dimensions or mass of the textile itself, such as textile width or industry weight. Textile width refers to the horizontal dimension, while roll length refers to the length wound onto one roll.

The term bolt is often used in contexts referring to narrow-width woven goods, including those for kimono, while roll is used more broadly as a trading unit for textile. However, usage varies by site and by trading partner.

Frequently Asked Questions

How many meters are in one roll?

The length per roll is not fixed, and it varies depending on the type of textile, width, material, and manufacturing and distribution standards. When placing orders or calculating fabric consumption, do not rely only on the term “one roll”; check the actual roll length and textile width shown for each product.

What should be checked when buying by the roll?

In addition to roll length, textile width, quantity, and whether cut sales are available, confirm whether the items can be matched within the same lot. For mass production, it is important to plan the required amount including cutting loss, pattern matching, and shrinkage allowances in order to reduce the risk of color differences and texture differences.
