The dimensional stability to washing will directly influences the stability of clothing shape and beauty of clothing, thus influences the use and wearing effect of garments. Dimensional stability to washing is an important quality index of garments.
Definition of Dimensional Stability to Washing
Dimensional stability to washing refers to the size change in the length and width of the garment after washing and drying, which is usually expressed as a percentage of the original size change.
Influencing Factors of Dimensional Stability to Washing
1.Fiber composition
Fiber with bigger moisture absorption will expand after soaking in water, so that its diameter will increase and length will shorten. The shrinkage is obvious.
2.Structure of fabric
Generally, dimensional stability of woven fabric is better than knitted fabric, and dimensional stability of high density fabric is better than low density fabric.
3.Production process
During the spinning, weaving, dyeing and finishing process, fibers are subjected to a certain degree of mechanical force, so that fibers, yarns and fabrics have a certain elongation. When fabrics are soaked in water in a free state, the elongated part will be retracted to varying degrees, which causes the shrinkage phenomenon.
Washing and drying process
The washing process, drying process and ironing process all will influence the shrinkage of fabric. Generally washing temperature is higher, the stability of fabric is poorer. Drying method also has a certain influence on the shrinkage of fabric. Tumble drying influences the fabric size the most greatly.
Feltability of wool
Wool has scales on the surface. After washed, these scales will be damaged, so there will be shrinking or deforming problem.
Improvement Measures
- Blending
- Select the tightness of the yarn
- Preshrink setting
- Choose a suitable ironing temperature according to the composition of fabric, which can improve the shrinkage of fabric, especially for fabric easy to crease after washed.
