This service is free of charge and is usually available within 3 days of the request. Garments factories should have fusing reports for every fabric they use and should request every new bulk production. These reports will cover the following:
⦁ Fusing conditions
⦁ Temperature: Glue – Line temperature is the temperature between the interlining adhesive and the fabric during the fusing process.
⦁ Fusing / Dwell time: Is the amount of time the fusing sample is exposed to the heat during the fusing.
⦁ Pressure: Roller / Belt pressure is the pressure exerted to the fabric and interlining during the fusing process.
⦁ Bond Strength: Bond strength is the force needed to separate the fused interlining from the shell fabric.
⦁ Surface Appearance: The fuse fabric is visually inspected in good lighting condition. The surface should remain smooth and even.
⦁ Dimensional Change: Sample ate measure before and after fusing to asses If there is any shrinkage or growth.
11.2 Fusing Machine Calibration: Fusing machine must be calibrated twice daily for Temperature, Fusing / Dwell time, Pressure Evenness. At lest two people in the garment factory should be trained to calibrate the fusing machine. The machine calibration record should be filled in twice daily and record stored with machine.
i) To test the Temperature: Set the fusing machine to the conditions recommended in the fusing interlining suppliers report. Allow 20-30 minutes for the machine to heat up and stabilize, then place 3 temperature strips across the width of the machine, (Left, Center, and right). Read the temperature from the strips once they have gone through the machine.
ii) To test for Fusing / Dwell Time: Set the time as recommended in the fusing report. Check the fusing / dwell time by using an accurate stop watch to time a non-adhesive fabric swatch going through the machine. Start timing when the fabric enters the heating cabinet / zone.
⦁ To Test for Pressure Evenness: Do the bond strength test on the 3 positions across the machine Left, Center, and Right at the same time. Put Carbone paper on the white paper Then give the machine.
12. Needle Detection: Before packing garments, all garments should pass by needle detector machine. After detection the goods must be keep in a metal free zone.
Before start pass garments by needle detector machine. Machine must be calibration by ferrous card in 9-point system.
13. Moisture /Mould Prevention: It is very important that the factory prevent the product from mould/ moisture.
14. inspection: All orders must be inspected and tested records are required to be keep from each major stage of production. The inspection area needs to provide a table in a suitable size for the product. A light source minimum 1000 Lux. Inspection to be perform:
i) Inline inspection: Factory must be performed inline inspection. Keep record defect % and defective %.
ii) End line inspection: Factory must be performed end line inspection. To ensure all that all produce goods are correct, style, quality, measurement and all kinds of labeling position. Doing measurement minimum 2 time in every day and keep record.

At lest two people in the garment factory should be trained to calibrate the fusing machine. The machine calibration record should be filled in twice daily and record stored with machine.
i) To test the Temperature: Set the fusing machine to the conditions recommended in the fusing interlining suppliers report. Allow 20-30 minutes for the machine to heat up and stabilize, then place 3 temperature strips across the width of the machine, (Left, Center, and right). Read the temperature from the strips once they have gone through the machine.
ii) To test for Fusing / Dwell Time: Set the time as recommended in the fusing report. Check the fusing / dwell time by using an accurate stop watch to time a non-adhesive fabric swatch going through the machine. Start timing when the fabric enters the heating cabinet / zone.
⦁ To Test for Pressure Evenness: Do the bond strength test on the 3 positions across the machine Left, Center, and Right at the same time. Put Carbone paper on the white paper Then give the machine.
12. Needle Detection: Before packing garments, all garments should pass by needle detector machine. After detection the goods must be keep in a metal free zone.
Before start pass garments by needle detector machine. Machine must be calibration by ferrous card in 9-point system.
13. Moisture /Mould Prevention: It is very important that the factory prevent the product from mould/ moisture.
14. inspection: All orders must be inspected and tested records are required to be keep from each major stage of production. The inspection area needs to provide a table in a suitable size for the product. A light source minimum 1000 Lux. Inspection to be perform:
i) Inline inspection: Factory must be performed inline inspection. Keep record defect % and defective %.
ii) End line inspection: Factory must be performed end line inspection. To ensure all that all produce goods are correct, style, quality, measurement and all kinds of labeling position. Doing measurement minimum 2 time in every day and keep record.
⦁ Finishing / Pressing inspection: Factory must be performed finishing inspection. Overall workmanship, pressing, appearance, measurement. Keep record defect % and finishing return.
⦁ Pre- final inspection: Factory must be doing pre-final inspection before offer pre-final inspection to M&M Suits Maker and Exporters. If factory pre-final inspection is pass then offer to M&M Suits Maker and Exporters for pre-final inspection.
