According to experience, due to the limited heating area of steam iron, in order to ensure uniform fiber stretching, mohair sweater adopts local, segmented, segmented and heated stretching methods. The fiber can't be stretched much at a time, so it needs to be heated and stretched repeatedly. Know the total length of stretching before stretching, so as to know the stretching length of each segment. After all stretching, we should measure the total length with a ruler. If the length is not enough, we can repeat it. Pay special attention not to oversize, and finally adjust it appropriately. The operation should be carried out on the ironing table, and a blanket can be spread on the desktop at home. After all, it is best to heat, shape and cool with a photo machine.
