The first step is to extrude the PLA filaments, which are then cooled. In most cases, these filaments are quenched in water. For small monofilament fibers, however, the cooled monofilament fibers are quenched in air chambers. The diameter of the PLA monofilament influences the speed of the rolls in the water bath, so larger monofilament has a lower extrusion speed. The spinners in this process typically reach a spinning speed of 30 to 100 m per minute.
This polymer is made by a 3-D printer using a conductive filament. The material is heated to a high temperature and spun on a specialized machine. A spinneret is used to draw the polymer through the holes. Once the filaments have been drawn into fibers, they are dried at temperatures between 50 and 500 °C. The filaments' initial diameters are not the same as their final diameters.
To make PLA monofilament yarn, you need to cool the filaments in an appropriate water bath. The large diameter filaments are quenched in a water bath, while the small monofilament fibers are quenched in air chambers. The diameter of the fibers influences the speed of the extrusion rolls in the water bath. The bigger the fibers, the slower the extrusion speed will be. Generally, a large diameter polyfilament is spun at 30 to 100 m per minute.
The stress-strain curve of 3D-PPOT-TPE materials showed that it had higher tensile strength at rupture, which is independent of the orientation and weft density of the textiles. As a result, this polymer material is eco-friendly and non-toxic. It is used in high-grade toothbrush filaments, and is also found in surgical sutures, tea bags, and medical devices.
The properties of this material are similar to those of PET. Its melting point is 160 deg C. Its density is 1.24g/cm3. Its diameter ranges from 0.07 to 3.0mm. Its properties make it a desirable material for a wide range of applications. The advantages of this type of synthetic fiber are that it is non-toxic and environmentally friendly. The use of these materials is growing in several industries.
High-quality PLA fibers can be used for many industrial applications. Its low-cost and easy-extruding characteristics make it a popular choice. It is also strong, durable, and biodegradable, which makes it a popular choice for textiles. Although it is a good alternative to PP, there are some disadvantages to this material. You should avoid it if it has the potential to damage your clothes.
