1. Raw materials
The raw materials of medical clothes are different, and the water reduction rate is different. In general, fibers with greater hygroscopicity swell after immersion, increase in diameter, shorten in length, and have a large water shrinkage rate. If there are viscous fibers, it absorbs water up to 13%. Synthetic fiber fabric has poor hygroscopicity, and its moisture shrinkage rate is small.
2. Density
Medical uniforms have different fabric densities and different shrinkage rates. If the latitude and longitude densities are similar, the shrinkage rates of the warp and weft are also very close. After the density of medical uniforms, the warp direction shrinks by nine, and vice versa; the weft density is greater than the dense fabric, and the weft shrinkage is also greater.
3. Yarn thickness
The shrinkage varies with the yarn count. The shrinkage rate of spun yarn thick cloth is larger, and the shrinkage rate of spun yarn fabric is smaller.
4. Production process
The production process of medical clothing is different, and the shrinkage rate is also different. Generally speaking, in the process of weaving and dyeing, the fiber has to be stretched many times, the processing time is long, and the medical clothing with high tension has a large water reduction rate, and vice versa.
