Embodiment 1

[0013] A manufacturing method of carpet yarn, comprising the following process steps:

[0014] 1) Take 6 parts by weight of melamine cyanurate, 1.5 parts by weight of melamine polyphosphate, and 0.8 parts by weight of sodium zinc oxide, and make a modified flame retardant by hydrophobizing treatment with a coupling agent; the melamine cyanurate salt And the average particle size of melamine polyphosphate is 0.9μm, and the average particle size of sodium zinc oxide is 20nm;

[0015] 2) The modified flame retardant masterbatch is obtained by mixing the modified flame retardant and nylon 6 slices through high-speed dispersion mixing and twin-screw melt extrusion;

[0016] 3) The raw materials are metered into the hoppers of the three screw extruders respectively. Two of the hoppers are added with nylon 6 slices, the pre-dried modified composite flame retardant masterbatch and color masterbatch, and the other hopper is added with nylon. 6 slices, pre-dried polyetheresteramide and...

Abstract

The invention discloses a carpet yarn manufacture method, which comprises the following technical steps of: 1) carrying out hydrophobic processing on melamine cyanurate, melamine pyrophosphate and nano-zinc oxide by coupling agent; 2) carrying out high-speed dispersing and mixing and double-screw melt extrusion on modified fire retardant and polyamide-6 granula to obtain modified composite fire retardant master batch; 3) respectively metering and adding raw materials into the hoppers of three screw extruders; 4) ejecting two bundles of polyamide-6 fibers and one bundle of anti-static fiber; 5) gathering three bundles of fibers together to form a fiber bundle; after the fiber bundle is stretched via a stretching roller, causing the fiber bundle to enter a bulking device to form bulked yarn; cooling, forming and networking; generating a network node for lacing yarns periodically on the surface of the yarn; winding by a coiler to obtain a cheese; and obtaining the product. According to the carpet yarn manufacture method disclosed by the invention, the characteristics of abrasive resistance, resistance to soiling and rebound resilience of the polyamide-6 are almost kept for the carpet yarn. Meanwhile, the carpet yarn also has the composite function of permanent anti-static property and fire resistance.

Description

technical field [0001] The invention relates to the field of carpet yarn weaving, in particular to a manufacturing method of carpet yarn. Background technique [0002] In chemical fiber carpets, nylon has become an ideal material for high-end carpets recognized at home and abroad because of its good wear resistance, stain resistance, resilience and dyeing performance. The development and production of multi-functional nylon carpets will surely become the current main direction of the carpet industry. At present, multi-functional nylon carpets are mostly antistatic and stain-resistant. Although there are reports of successful research on flame-retardant nylon carpets, there are no industrialized products on the market. For antistatic and flame retardant dual-functional nylon carpets, the main reason is that it is more difficult to flame retardant nylon, and it is more difficult to achieve antistatic and flame retardant at the same time. According to literature reports, the ...
