What is Fusing Process in textiles ?
Fusing service is one kinds of alternative method of fabric joining which is widely used to attach the interlining. At present, apparel manufacturing cannot be imagined without fusing process. In fusing process cut components or separate parts of a lay (blocks of components) are fused with interlinings that are coated with thermoplastic resin. Fusing service certain components creates strength and stability and improves the shape and crease resistance of a garment. Fusing of the components is usually performed in a cutting room as this process must be performed after material cutting and before the final operations in a cutting process (quality control, sorting and bundling of cut components).Each apparel manufacturer persistently attempts to manufacture garments with instant sales appeal. Nevertheless, one of the vital materials, fusible interlining, which is utilised for nearly almost every component of outerwear, has no sales appeal because it is imperceptible to the consumer. The method of fusing interlining to the garments started in Europe in about 1950 and in Japan in about 1960. Today, about 80% of all garments necessitate the use of interlining.
Fusible interlining is the process where the wrong side of the fashion garment panel is fused with a thermoplastic resin and can be bonded with another strip of fabric by the proper application of pressure and heat at a specific temperature and time. The fusible interlinings improve the appearance of finished garments through:
Stabilisation and control of crucial regions of the garment. Strengthening of particular design features. Without much change in the draping quality of the top cloth. Maintaining the crisp and fresh look of the base fabric.
Fusing Presses and Their Characteristics: The fusing process is performed by special fusing presses. They can be divided into two groups according to the way they perform the work process: discontinuous work process (flat) fusing presses and continuous work process fusing presses.
Discontinuous work process fusing presses realise sequential, separated from each other fusing process. They are less productive and are suitable for small and medium production units. Continuous work process fusing presses enable an ongoing process by moving the components on a conveyor belt. They offer a higher level of productivity and are more energy efficient. Because of these advantages, continuous fusing presses are designed for different power production units and used more often.
Discontinuous work process fusing press: The discontinuous fusing press is generally flat bed, which has a heating zone with two work surfaces. The other arts are handle, head and buck. Depending upon the construction, there are two ways in which the work surfaces may move to open the press such as: an upper surface which folds sideways (fusing plate press)
