Finishing

Finishing after washing is crucial to restore the fabric's brightness, texture, and body. It involves rinsing to remove all soap or detergent residues, and often adding reagents to improve appearance and texture. Blueing agents counteract yellowing in white cotton fabrics caused by repeated washing. Ultramarine blue powder or liquid blue can be used in the last rinse; the fabric must be wet and free of folds to avoid patchy results. Optical brightening agents (fluorescent brighteners) absorb ultraviolet light and re-emit it as visible blue light, enhancing whiteness and counteracting both yellowness and grayness. They can be used on coloured fabrics without damaging colour. Starching and stiffening agents restore body lost during washing, making fabrics firm, smooth, and shiny. Starching also prevents dirt from directly contacting the fabric, making future washing easier. Common stiffening agents include starch (from wheat, rice, tapioca), gum acacia (from babool tree), gelatin, and borax. Borax enhances starch stiffness and forms a water-repellent film after ironing, maintaining crispness in humid climates. Application depends on fabric type and use; starch consistency and fabric wetness must be controlled. Drying is best done outdoors in sunlight with the wrong side facing out to speed drying, disinfect, and bleach whites. Delicate fabrics like silk, wool, and synthetics should be dried indoors to avoid damage and yellowing. Ironing removes wrinkles and sets creases using heat, moisture, and pressure. Electric irons allow temperature control suitable for different fibres. Moisture can be provided by ironing damp clothes or spraying water. Pressure is applied by moving or pressing the iron. Delicate fabrics require pressing rather than rubbing. Ironing boards should be padded and firm for effective ironing. After ironing, clothes are folded or hung for storage.
