The role of ironing

1. Pre-shrinking and finishing of raw materials

Before cutting clothing surfaces and accessories, especially cotton, wool, silk, linen, etc. Natural fiber fabrics need to be pre-shrunk on the sides and accessories through different methods such as spraying and water-jet ironing, and remove wrinkles from the fabrics to create conditions for layout, pattern making, cutting and sewing.

2. Thermoplastic deformation

Use the thermoplastic deformation principle of clothing and use ironing techniques and techniques such as pushing, returning, and pulling to appropriately change the stretch and contraction of clothing fibers and the warp and weft of clothing. The density and direction of the tissue shape the three-dimensional shape of the garment, making up for the lack of modeling techniques such as darts, door openings and segmentation settings in structural drawing, so that the garment meets the requirements of human body beauty and comfort.

3. Shaping and shaping

In order to improve the sewing quality of clothing and reduce the difficulty of sewing, during the sewing process of semi-finished products, many parts of the garment must be processed according to the process. According to the requirements, ironing operations such as bisecting, discounting, and compaction are carried out, such as folding, buttoning seams, split seams, ironing, and solidification, etc., in order to achieve long-lasting shaping such as straight seams and pleats and flat, thin and solid welts. The shaping and ironing of finished garments can make the garments have a three-dimensional appearance that is smooth, crisp, beautiful, and suitable for the body.

4. Correct defects

Use the expansion, elongation, contraction and other properties of the fibers in the fabric to correct the defects caused by the sewing of clothing through spray and water spray ironing. For example, wrinkles caused by uneven stitching, uneven arcs, over-tightening of sutures, "dimples" caused by loosening of small parts, uneven lengths of parts, seams, collars, lapels, bag flaps, etc. Defects can be corrected through ironing techniques to improve the quality of clothing.
