Abstract

The invention discloses a production process of a coloured polyester filament nonwoven. The production process of the coloured polyester filament nonwoven comprises the steps of: heating ethanol solution, adding konjac glucomannan to stir, then, adding a silane coupling agent KH550 to stir, heating under reflux, adding potassium titanate whiskers and nano-zinc oxide to stir, standing, filtering, drying, grinding, and sieving, so that an antibacterial agent is obtained; feeding a polyester chip into a high-level bin by adopting a dry hot air conveying device, performing pre-crystallization by feeding into a crystallizer through a rotary valve, enabling the polyester chip to pass through a drying tower, furthermore, performing countercurrent contact with dry hot air introduced from the bottom of the drying tower, and performing moisture and heat transmission, so that a pre-processed dry chip is obtained; mixing the pre-processed dry chip, the antibacterial agent, a dispersing agent withcolour master batches, entering a spinning assembly after extrusion melting, obtaining nascent fibres by spinning, and obtaining fibre filaments by cooling and drawing; and, uniformly laying the fibrefilaments by splitting filaments and placing filaments, so that a fibre web is obtained, obtaining a preliminary entanglement through a pre-needling machine, and then, reinforcing by needling througha main needling machine, so that the coloured polyester filament nonwoven is obtained.

Description

technical field [0001] The invention relates to the technical field of nonwoven fabrics, in particular to a production process of colored polyester filament nonwoven fabrics. Background technique [0002] The market demand for spunbonded needle-punched nonwovens is very large. Compared with foreign countries, the development of domestic spunbonded needlepunched nonwovens started relatively late, and the variety is relatively single. It is ahead of the world in terms of raw materials, technology and equipment. There is still a certain gap in the product. At present, with the serious homogeneity of needle-punched non-woven products, the competitive pressure of chemical fiber enterprises is increasing day by day, and they are developing differentiated products with high added value. The production of spun-bonded needle-punched non-woven fabrics is difficult and has high technical content. As the technology matures, it will inevitably attract more companies to develop it. [0...
