The shrinkage of garden clothing fabric refers to the shrinkage of fabric after washing or soaking. Shrinkage refers to the phenomenon that the length or width of fabric changes to a certain extent after washing, dehydration and drying. The shrinkage of synthetic fiber and blended fabric is small, followed by wool, flax and cotton, and silk is large. The big ones are viscose, rayon and wool fabrics.
There are different yarn count and shrinkage of garden clothing. The shrinkage of coarse fabric is higher than that of fine fabric. The shrinkage of the fabric varies with the production process. Generally speaking, in the process of textile dyeing and finishing, the fiber needs to be stretched many times and the processing time is long. The higher the tension, the greater the shrinkage of the fabric. The higher the tension, the smaller the shrinkage of the fabric.
Natural plant fibers (such as cotton and hemp) and regenerated plant fibers (such as viscose fiber) are more likely to absorb moisture and expand than synthetic fibers (such as polyester and acrylic acid) and have higher shrinkage, while wool and felt are more likely to be due to the scale structure of surface fibers. The factors that affect the dimensional stability of the alloy.
Generally speaking, the dimensional stability of woven fabric is better than that of knitted fabric, and that of high-density fabric is better than that of low-density fabric. Generally speaking, the shrinkage of plain fabric is less than that of flannel fabric, and that of knitted fabric is less than that of rib fabric. There is tension on the fabric because the fabric will inevitably be stretched during the dyeing and finishing process.
However, the fabric will release tension in water, so we find that the fabric will shrink after washing. In practical application, pre shrinking method is usually used to solve this problem. Washing care includes washing, drying and ironing. These three steps will affect the fabric shrinkage. For example, the dimensional stability of hand washed samples is better than that of machine washed samples, and the washing temperature also affects the dimensional stability. Generally speaking, the higher the temperature, the worse the stability. The drying method of the sample also has a great influence on the shrinkage of the fabric.
