A kind of far-infrared, antibacterial and mite-removing composite polyester functional fiber and its manufacturing method

Abstract

The application relates to far-infrared antibacterial anti-mite composite polyester functional fiber and a production method thereof; the far-infrared antibacterial anti-mite composite polyester functional fiber comprises a far-infrared additive and an antibacterial anti-mite additive accounting for 5% and 7% respectively by weight in the fiber; with the far-infrared additive and the antibacterial anti-mite additive, the far-infrared antibacterial anti-mite composite polyester functional fiber can absorb far-infrared radiation, can generate heat and provide great antibacterial anti-mite action, and is highly practical; through an additive carrier, the far-infrared additive and the antibacterial anti-mite additive can be dispersed evenly in the fiber, and agglomeration of nanoparticles is effectively avoided.

Description

technical field [0001] The present application relates to the technical field of polyester fiber and its manufacture, in particular to a far-infrared, antibacterial and mite-removing composite polyester functional fiber and its manufacturing method. Background technique [0002] Polyethylene terephthalate (PET) is called polyester for short. Because of its excellent characteristics, it is favored by people. In recent years, polyester has developed rapidly in both fiber and non-fiber fields, and the demand is expanding; industrialization The mass-produced polyester fiber is made of polyethylene terephthalate and is widely used in the textile industry. It is an important raw material for fabrics such as clothes, bedding, interior decoration, and carpets. Due to its application process, It is very easy to breed bacteria. Therefore, it is of great practical significance to modify polyester textile fibers to have antibacterial and mite-removing effects. [0003] Far-infrared pol...

Problems solved by technology

[0004] In the process of realizing the functionalization of polyester fibers, by adding substances with far-infrared, antibacterial and mite-removing effects, it is of practical significance to realize the functional application of polyester fibers; currently the functionalized fiber fabrics on the market are mainly through additives. To realize, as the patent 201110261719.7 reports a kind of processing method of durable antibacterial and deodorant fiber fabric, this method is to add nanoscale inorganic antibacterial agent in the high polymer powder with 3%-30% weight ratio, mix evenly, The antibacterial masterbatch is formed by screw granulation technology. The antibacterial masterbatch is mixed with a high polymer at a ratio of 0.3%-10%, spun, and the fabric is formed after spinning and weaving, and then finished with an antibacterial agent. Using the invention The fiber fabric processed by this method has the advantages of good antibacterial effect and strong durability; however, there are defects in melt spinning by adding additives directly into fiber chips, for example, due to the small particle size of additives, high surface activity and free energy , the thermodynamic state is unstable, it has a tendency to spontaneously agglomerate, and it is easy to agglomerate, which will greatly affect the advantages of functional particles in polyester fibers, resulting in no obvious modification effect of polyester fibers
