ironing Heat treatment of garment parts or garments. role The role of ironing is: (1) smooth, eliminate fabric crepe. (2) Weft filling, correct the deviation of weft silk strands formed in the dyeing and finishing process of the fabric, so that the fabric can be restored to facilitate cutting and sewing. (3) pre-expansion, prevent the garment piece in sewing due to heat and expansion phenomenon. (4) deformation, the use of fabric plasticity, the fabric local deformation, make the shape of the garment from straight to arc or from arc to straight, in order to process fit garment. (5) Plastic, modify the appearance of the garment, make up for the shortcomings in the process of operation, so that the appearance is flat, stick to the clothing, not warped. conditions Ironing requires three conditions: temperature, humidity and pressure. Temperature is the key. According to the performance characteristics of all kinds of fabric, the added heat and the inherent heat resistance of the fabric should be adapted. Too high a temperature will damage the fabric, too low a temperature will not work. Usually grasp the ironing temperature: synthetic fiber 90 ~ 160℃ (polyamide fiber 90℃), silk 120℃, wool 160℃ (humidification cloth 200℃), cotton 180℃, hemp 190℃. The size and length of ironing pressure, according to the thickness of clothing and raw material inherent properties. Generally thin material loose required less pressure, ironing time is short, thick material dense on the contrary. Fabric cannot be ironed directly on the face of the table, need mat thin blanket, wool product still needs wet cloth on the cover, in order to maintain the dress neat and do not produce reflective light. methods Ironing methods are mainly: (1) push, return, pull. It is a traditional ironing technique for processing woolen clothing, which can make the flat piece produce three-dimensional modeling and the effect of clothing fitting

Rolling and inlay are often used in combination, giving a delicate and

sewing The process of stitching pieces of clothing into a garment. It can be divided into hand sewing process, machine sewing process, special process, etc. Hand sewing process Garment processing technology The process of sewing by hand needle. It is a traditional Chinese handicraft skill. Many stitches and their functions cannot be replaced by modern sewing machines. With fine stitch, smooth, rich needling and other characteristics, known as high-grade technology. Commonly used hand sewing process needle see table. The main tools of hand sewing are hand stitches and headbands. 7 ~ 9 needles should be used for fine fabrics such as silk; Keyhole nail should be used 4 ~ 5 needle, general wool with moderate thickness of 6 ~ 8 needle. Machine sewing process Garment processing technology Garment processing technology The process of sewing with a sewing machine. It has the advantages of neat stitch and high efficiency. Commonly used machine sewing processes are as follows. (1) seam (including pocket seam); Stitch the pieces together. Used for dark stitching garment piece combination or pocket cover, collar, cuff, etc. (2) Sewing: one layer of garment edge over another layer of garment edge sewing, and then for the second or third time.
