Minimum Colour Quantity Deciding a Range Plan before Design Does
Minimum colour quantities set dye vessel efficiency and enforce range plan fabric allocations long before garment sketches reach the pattern desk.
Loom State
Raw Fabric Condition
The immediate state of a textile material as it is removed from the weaving machine describes its primary form. This loom state fabric contains all the temporary additives and structural stresses introduced during the manufacturing process. It is often stiff, rough to the touch and somewhat oily because of the sizing agents applied to the warp yarns.
These coatings are necessary to protect the yarns from breaking under the high tension and friction of the loom. The material at this stage is usually wider and longer than it will be after finishing because it has not yet undergone any shrinkage. It is also known as greige or gray goods in the global textile trade.
This raw material must be further processed before it is suitable for use in apparel or home furnishings.
Sizing Agent Removal
Pre-treatment of the fabric is the first step in converting it from its raw form into a finished product. The loom state material is subjected to a process called desizing, which washes away the starch or synthetic chemicals from the yarns. This is followed by scouring to remove natural oils, waxes and any dirt that accumulated during weaving.
These steps are essential for making the fabric absorbent and receptive to dyes and finishes. If the sizing is not completely removed, the fabric will dye unevenly and have a poor hand feel. Bleaching may also be necessary to remove the natural color of the fibers and provide a clean base for bright shades.
This transition from raw to prepared fabric is a fundamental part of the textile finishing process.
Dimensional Contraction Risk
Stability of the fabric dimensions is a major concern when moving from the weaving room to the wet processing area. The loom state material is under high tension while it is being woven, and this tension is locked into the structure of the fabric. When the fabric is wet out for the first time during desizing or scouring, these stresses are released and the material shrinks.
This contraction can be significant, especially for cotton and other natural fibers. Manufacturers must account for this shrinkage when planning the width and length of the finished goods. If the shrinkage is not controlled, the final fabric may be too narrow or too dense for the intended garment style.
Processes such as mercerization and heat setting are used to stabilize the fabric and prevent further changes in size.
Material Inventory Value
Accounting and production planning at the textile mill rely on the measurement of the fabric in its initial form. The loom state weight and length are recorded for every roll as it is completed on the weaving floor. These figures are used to track the efficiency of the weaving room and the consumption of the yarn.
The value of this inventory is lower than that of the finished fabric because it still requires several expensive processing steps. However, it represents a significant investment in raw materials and labor for the company. Mills often store large quantities of this material so that they can quickly respond to orders for different colors and finishes.
Accurate tracking of the loom state goods is necessary for managing the cash flow and the production schedule of the mill.
