Problems solved by technology

[0004] The purpose of the present invention is to overcome the problems of deformation of nonwoven fabric and discoloration of colored polyester staple fibers existing in the process of obtaining waterproof and oil-proof properties of existing colored nonwoven fabrics through padding, and to provide a waterproof and oil-proof colored polyester staple fiber The manufacturing method, it attaches the waterproof and oil-repellent agent to the surface layer of the colored polyester staple fiber step by step, so that the surface of the colored polyester staple fiber has waterproof and oil-proof properties, and the non-woven fabric produced with this colored polyester staple fiber It has waterproof and oil-proof function itself, and it does not need to be finished by padding to obtain waterproof and oil-proof function. It is not easy to deform when drying, and the colored polyester staple fiber will not change color. It simplifies the process, saves energy consumption and reduces production costs.

Embodiment 1

[0024] Polyester polymer: Imported white polyester bottle flakes (clean flakes). Production of 3D black waterproof and oil-resistant polyester staple fiber.

[0025] (1) Dry the white polyester bottle flakes (ie polyester polymer) in a drum for 8 hours, feed 95% polyester polymer and 5% color masterbatch to the screw of the spinning production line by weight In the extruder, it is heated and melted to form a melt. The heating temperatures of the seven zones of the screw are: 275~285°C, 275~280°C, 280~285°C, 285~290°C, 285~290°C, 280~285°C ℃, 280~285℃.

[0026] (2) The melt flows out from the screw, passes through the pre-filter, is metered by the spinning pump, and is extruded through the spinneret hole at a pressure of 8.0 MP. Under the action of cold air, the melt is elongated, thinned, cooled and solidified to form nascent fibers. The speed at which the filaments are ejected from the spinneret hole is 1000m / min. The primary fiber silk is fed into the tow drum after roll...

Embodiment 2

[0041] Polyester polymer: Imported white polyester bottle flakes (clean flakes). Production of 3D red waterproof and oil-resistant polyester staple fiber.

[0042] (1) Dry the white polyester bottle flakes (ie polyester polymer) in a drum for 12 hours, feed 98% polyester polymer and 2% color masterbatch to the screw of the spinning production line by weight In the extruder, it is heated and melted to form a melt. The heating temperatures of the seven zones of the screw are: 275~285°C, 275~280°C, 280~285°C, 285~290°C, 285~290°C, 280~285°C ℃, 280~285℃.

[0043] (2) The melt flows out from the screw, passes through the pre-filter, is metered by the spinning pump, and is extruded through the spinneret hole at a pressure of 10.0 MP. Under the action of cold air, the melt is elongated, thinned, cooled and solidified to form nascent fibers. The speed at which the filaments are ejected from the spinneret hole is 1200m / min.

Abstract

The invention discloses a manufacturing method of water-proof and oil-proof coloured polyester staple fibers, aiming at solving the problems of nonwoven fabric deformation and coloured polyester staple fiber discoloration of the traditional coloured nonwoven fabric in the process of obtaining water-proof and oil-proof properties through padding finishing. In the invention, water-proof agents and oil-proof agents are attached to the surfaces of the coloured polyester staple fibers step by step and layer by layer so as to enable to the surfaces of the coloured polyester staple fibers to achieve the water-proof and oil-proof properties; a nonwoven fabric per se, produced by using the coloured polyester staple fibers, has water-proof and oil-proof functions, without being subjected to padding finishing to obtain the water-proof and oil-proof functions, and has the characteristics of difficulty in deformation and difficulty in discoloration of the coloured polyester staple fibers when dried; and in addition, the process flow is simplified, the energy consumption is lowered and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of polyester staple fiber production, in particular to a method for manufacturing colored polyester staple fibers with waterproof and oil-repellent functions. Background technique [0002] Polyester staple fibers are used in a wide variety of industries. According to the Japan Chemical Fiber Association, polyester staple fibers accounted for more than 78% of the 41.6 million tons of chemical fiber output in the world in 2009. There are also many differentiated and functional varieties of polyester fibers, such as three-dimensional crimps, special-shaped cross-sections, low melting points, Functional polyester staple fibers such as high shrinkage, antibacterial, mildew-proof, and high water absorption. Among all functional products, there is no colored polyester staple fiber with waterproof and oil-proof functions. At present, the colored non-woven fabric products with waterproof and oil-proof function on th...
