Composite functional fabrics have antibacterial, anti-radiation, antistatic, water-repellent, and stain-resistant functions, and are popular with people.

[0003] Polyamide and polyester fibers are widely used in the clothing industry due to their high strength, quick-drying properties, and good wear resistance. However, chemical fibers have low moisture absorption and easily accumulate static electricity, especially in low-humidity areas such as the western and northern regions of China. During the wearing process, static electricity can cause a "crackling" phenomenon. At the same time, static electricity can easily attract dust in the air, causing the clothes to become dusty. Therefore, it is necessary to develop a dustproof and antistatic polyester DTY filament. SUMMARY

[0019] The utility model is further explained in combination with the drawings and specific embodiments.

[0020] Embodiment one

[0021] In combination with Figure 1 and Figure 2 , the embodiment is explained in detail. The dustproof and antistatic polyester DTY filament according to the embodiment comprises high-shrinkage filament 1 and polyester DTY filament 2 connected with each other through network points 3; the high-shrinkage filament 1 has a boiling water shrinkage rate higher than 25%; the cross section of a single filament in the polyester DTY filament 2 comprises a core layer 21 and an antistatic polyester part 22 and an antibacterial polyester part 23 arranged outside the core layer 21. The network points 3 are network nozzles used to network the parallel high-shrinkage filament 1 and the polyester DTY filament 2, that is, the high-speed airflow is used to intertwine and fix the filaments at the network points 3. The number of the network points 3 is 20-30 per meter.

[0022] Further, the high-shrinkage filament 1 is a high-shrinkage polyester filament or a high-shrinkage polyacrylonitrile filament. Fibers with a boiling water shrinkage or dry heat shrinkage higher than 25% are called high-shrinkage fibers, and the main feature is that high shrinkage is generated after being treated by boiling water or dry heat, and the shrinkage rate reaches 25%-50% or even higher. In this embodiment, a high-shrinkage polyester filament is selected. The high-shrinkage polyester filament is obtained by physically or chemically modifying the polyester to obtain a low-crystalline, high-orientation supramolecular structure. When the high-shrinkage fiber is heated at a certain temperature, due to its low crystallinity, the binding force on the macromolecular segment movement is light, which makes the originally highly oriented macromolecules de-orient, thereby making the high-shrinkage polyester filament generate high shrinkage.

[0023] Further, the core layer 21 is a PET component, and the melting point of the PET component is 255-265°C. A conventional PET polyester is used, which has the characteristics of high strength.

[0024] The antistatic polyester part 22 is obtained by adding an antistatic component, such as carbon black, to the PET polyester chip, so that it has a conductive property, thereby making the DTY long yarn have an antistatic effect, avoiding the adsorption of dust due to static electricity. The antibacterial polyester part 23 is obtained by adding an antibacterial substance, such as zinc oxide, to the PET polyester chip, so that it has an antibacterial effect.

The dustproof antistatic polyester DTY long yarn involved in this embodiment is different from that of Embodiment One in that the dustproof antistatic polyester DTY long yarn further comprises a nylon-based carbon black conductive filament 4. The use of the nylon-based carbon black filament 4 further improves the antistatic effect and dustproof effect of the dustproof antistatic polyester DTY long yarn, and the nylon-based long yarn used has good wear resistance.

[0027] Embodiment Three

[0028] In combination Figure 4 The embodiment is described in detail. The dustproof antistatic polyester DTY long yarn involved in this embodiment is different from that of Embodiment One in that the dustproof antistatic polyester DTY long yarn further comprises a high-hygroscopic nylon long yarn 5, and the hygroscopicity of the high-hygroscopic nylon long yarn is greater than or equal to 4%. The high-hygroscopic nylon yarn is a DTY textured yarn, and the fineness is 70D / 68F nylon-6.
