Problems solved by technology

[0002] The traditional flame retardant monofilament is made of PET chips with flame retardant added, the monofilament is not smooth enough, and the flame retardant effect is poor
Moreover, because the flame retardant contains heavy metal components, the amount of addition is not controlled accurately, which does not meet environmental protection requirements.

Embodiment Construction

[0010] like figure 1 As shown in the above, a method of manufacturing PET flame-retardant monofilaments is first to put polyester chips into drying equipment such as a dryer to dry, and then the dried polyester chips are mixed with retardant oil and color masterbatch into a suction bucket to melt. The retardant oil container of the present invention is connected with a gauge and then connected with a suction barrel, which can accurately ensure the added amount of retardant oil. The melted material mixed and melted is divided into strips through the spinneret, and the wire is drawn and extruded repeatedly to obtain the required wire diameter before winding.

[0011] The percentage by weight of each component of the PET flame-retardant monofilament of the invention is: 85-95% of polyester chip; 12-4.6% of flame-retardant oil; 3-0.4% of color masterbatch. The optimum weight percentage of each component of PET flame-retardant monofilament is: polyester chip 91%; retardant oil 8%;...

Abstract

The invention discloses a PET flame-retardant monofilament and a production method thereof. The PET flame retardant monofilament comprises the following components in weight percentage: 85 to 95 percent of polyester slice, 12 to 4.6 percent of flame retardant oil, and 3 to 0.4 percent of master batch. The production method comprises the following steps: after the polyester slice is dried, the flame retardant oil and the master batch are mixed and are melted in a suction bucket; a flame retardant container is connected with the suction bucket through a meter; and the molten material is split through a spinneret plate, is drafted and extruded repeatedly, and is wrapped up until the required filament diameter is obtained. The monofilament formed by the method has smooth texture, can improve flame retardant effect, reduce heavy metal components, and more accords with the requirement of environmental protection.

Description

technical field [0001] The invention relates to a PET flame-retardant monofilament and a manufacturing method thereof. Background technique [0002] The traditional flame retardant monofilament is made of PET chips with flame retardant added, the monofilament is not smooth enough, and the flame retardant effect is poor. Moreover, because the flame retardant contains heavy metal components, the amount of addition is not controlled precisely, and does not meet environmental protection requirements. Contents of the invention [0003] The purpose of the present invention is to provide a PET flame-retardant monofilament and its manufacturing method. The monofilament formed by it has a smooth silk quality, improves the flame-retardant effect, reduces heavy metal components, and is more in line with environmental protection requirements. [0004] In order to achieve the above object, the present invention is realized by the following technical solutions. [0005] A PET flame-re...
