Original Title: Quality Control of Garment Finishing Keyhole Nailing, Ironing and Decontamination After the completion of the sewing process, clothing needs to go through the whole process before it can become a commodity. After finishing, the garment goes through the process of keyhole, button, washing, decontamination, ironing, inspection and packaging. After ensuring that each garment is clean, smooth and beautiful and meets the standards, it will be packed and shipped for sale. Finishing link is the last link of garment quality control. It is necessary to hold the last quality pass in this link to prevent the occurrence of unqualified products and prevent the outflow of unqualified products, which is the purpose of finishing quality control. The key to quality control in finishing is to ensure the appearance quality of clothing, especially the cleanness and smoothness of clothing. This paper focuses on the three links of buttonholing,tailor measure tape, ironing and decontamination of clothing. 1. Quality control of nail locking link The quality requirements of the buttonhole nail button are that the position is accurate, the nail button is firm, the button corresponds to the eye position, the buttonhole thread does not burst out, and the base cloth does not come out. The opening size shall be appropriate to ensure at least 6 threads in each buttonhole,bra measuring tape, and no less than two upper and two lower threads shall be sewn. When the fabric is thick, the buttonhole thread shall be wrapped with high feet, and the height of the feet shall be adapted to the thickness of the seam allowance, and the ends of the feet shall not be exposed. The metal button shall be complete and free of rust and discoloration, the four-way button shall be firm, and the force required for pressing and opening shall be appropriate. In order to ensure the accuracy of the button position and eye position, the corresponding position of the garment piece should be positioned in advance. The use of locking nail equipment is reasonable, and the width of the opening knife edge is suitable for the diameter of the buckle. At present, all kinds of buttonholes and button nailing equipment are complete, and different button types are suitable for different button nailing equipment. If the button is specially required to be sewn manually, garment measuring tape ,keychain tape measure, the number of sewing threads in the buttonhole shall be ensured, and the sewing thread shall be threaded into the buttonhole at least twice when sewing the button. Round head keyhole equipment is required for thicker fabrics and thicker button keyholes. Pay attention to the direction of the buttonhole: The buttonhole of the shirt is opened horizontally at the collar seat and the sleeve cuff, and the placket and the sleeve slit are opened longitudinally, generally using a flat-head buttonhole machine; The buttonhole on the placket of the suit jacket is horizontal, a round buttonhole machine is used, and the round head is positioned on one side close to the spigot; The buttonholes in the back pockets of trousers and skirts are longitudinal, and the buttonhole machine can be used when the buttons are small and thin.

For suits and overcoats, there is a saying that « three points make seven points hot ». The collar, sleeve, shoulder, chest, back and hem of this kind of clothing have professional ironing equipment. Through the final ironing, the fabric and clothing are shaped to get a crisp appearance. The general requirements for ironing quality are smoothness, no yellow water stains, smooth shoulders, flat collar, crisp chest and smooth back. Ironing quality control should coordinate the temperature, pressure and steam of ironing, and adjust the appropriate parameters. The suit coat must be ironed with ironing equipment to achieve the desired effect. Knitted garments have relatively low requirements for ironing, while woven products rely heavily on ironing, which can give products a neat and flat appearance. In addition to the ironing of the post-finishing link, it is also necessary to do a good job of the middle ironing in the sewing link. 3. Quality control of decontamination treatment Garment will produce some pollutants such as positioning marks, threads, hair and so on in the production process, especially the filling debris in the processing of woolen clothing and cotton clothing will often be adsorbed on the clothing fabric. In order to make the clothing clean and beautiful, the final decontamination treatment must be done in the finishing process. Clothing standards require that there should be no residual threads (threads connected with clothing) on clothing, and consumers do not want to see the residual threads inside and outside clothing. Garment enterprises will do the work of thread cutting, in addition to manual thread cutting, there are now professional equipment for suction thread cutting and suction thread. The dander adsorbed on the clothing can be removed by suction equipment or by decontamination tape. Soap powder printing on clothing can be eliminated in the later period of high temperature ironing. There are also some clothing pollution that is not inevitable in production, but man-made pollution caused by poor on-site management, some of which need to be eliminated by washing. In order to eradicate such stains,printed tape measure, we should start from the source and do a good job of 6S work on the spot. The finishing link requires relatively low skills of employees, but this link requires employees to be careful and highly dependent on locking nails and ironing equipment.
