抗菌防霉丝的制备方法及该抗菌防霉丝制备的床垫
摘要：
本发明公开了抗菌防霉丝的制备方法及其该抗菌防霉丝制备的床垫，包括：(1.1)将抗菌防霉纳米粉和PET按15-20:80-85比率进行混合，制造出抗菌防霉的母粒，把母粒和普通PET按5-7:93-95比率混合，并进行熔融处理，制得抗菌防霉纤维；(2.1)先将抗菌防霉纤维进行切片、干燥处理；(2.2)将干燥处理后的抗菌防霉纤维切片进行熔融挤出处理，螺杆机挤出机对切片进行熔融和熔体的计量挤出，在进行混匀和塑化操作，熔体被塑化搅拌均匀后，在机内停留5-10分钟；(2.3)熔体自螺杆机挤出机挤出后，经熔体管道分配至纺丝机内进行熔体保温处理，然后通过纺丝机上喷丝板进行喷丝操作，制作出丝条；(2.4)然后对丝条进行拉伸处理形成成品丝，拉伸温度为270-290℃。本发明制备出的丝具有抗菌防霉的效果。
摘要（英）：

The invention discloses a preparation method of antibacterial and mildew-proof silks and a mattress prepared from the antibacterial and mildew-proof silks. The preparation method comprises the following steps: (1.1) mixing antibacterial and mildew-proof nanopowder and PET according to a ratio of (15-20): (80-85) to obtain antibacterial and mildew-proof masterbatch, mixing the masterbatch and ordinary PET according to a ratio of (5-7): (93-95), and melting to obtain antibacterial and mildew-proof fiber; (2.1) first slicing and drying the antibacterial and mildew-proof fiber; (2.2) performing melt extrusion on dried antibacterial and mildew-proof fiber slices, melting the slices and performing metering extrusion on a melt by using a screw extruder, uniformly mixing, plasticizing, and staying in the screw extruder for 5-10 minutes after the melt is plasticized and uniformly stirred; (2.3) after the melt is extruded from the screw extruder, distributing the melt into a spinning machine through a melt pipe, performing melt insulation, and performing pinning operation through a spinneret plate on the spinning machine to obtain silks; (2.4) then stretching the silks at a stretching temperature of 270-290 DEG C to form the finished silks. The silks prepared by the preparation method provided by the invention have antibacterial and mildew-proof effects.
