Description
Technical field
The present invention relates to the production technical field of carpet, be the production method of a kind of bio-based nylon 56 carpet bulked silk in detail.
Background technology
It is known that: carpet is as a kind of soft pavement, and history is the longest.The application on carpet of the nylon bulked silk is widely, the nylon bulked silk being applied at present on carpet has nylon 6 and nylon66 fiber two kinds, consumption reaches more than 40%, but nylon 6 and 66 is all petroleum-based products, so the environmental protection nylon carpet bulked silk developing bio-based should be future thrust.
Summary of the invention
The purpose of the present invention is that and overcomes the deficiencies in the prior art, and provides the production method of a kind of bio-based nylon 56 carpet bulked silk, and the nylon 56 carpet bulked silk produced, intensity, hygroscopicity are all high than nylon 6 and 66；Density is little, and loft is the best；Dyeing temperature is low, and color fastness is high, and dye low cost；Good flame resistance, is better than nylon 6 and 66.Nylon 56 carpet bulked silk is the most aggregated spinning of biofermentation and makes, and Bio-based content reaches 45%, is environmental protection recyclable regenerative nylon.
nullThe present invention uses following technical solution: the production method of a kind of bio-based nylon 56 carpet bulked silk，It is characterized in that，Comprise the steps，Respectively dried bio-based nylon 56 is cut into slices and color master-batch measures and mixes，Mixture is melted by the screw extruder with heater、Stirring mixing、Metering extrusion，Melt pipe through being carried out being incubated by high-temperature heat-conductive oil vapour enters spinning pump and precisely measures melt and pressurize，Precisely the melt of metering penetrates through spinneret abnormity spray orifice，Carry out being cooled into as-spun fibre by 270-295 DEG C of constant temperature and humidity air-flow produced by air conditioning system by spinning shaft，Carry out spinning oil by oil nozzle after as-spun fibre boundling to oil，The drawing-off of 2.5-3.0 drafting multiple is carried out through hot-rolling，Entrance converting pipe is carried out expanded being deposited on fiber by 190-205 DEG C of hot compressed air stream and forms curling，And be crimped solidifying to form buiky yarn by drum cooler cooling，Carry out network of yarns knotting through air knotter again and reduce loose，High speed winding head carries out package and forms finished product.
The invention has the beneficial effects as follows, the nylon 56 carpet bulked silk produced, intensity, hygroscopicity are all high than nylon 6 and 66；Density is little, and loft is the best；Dyeing temperature is low, and color fastness is high, and dye low cost；Good flame resistance, is better than nylon 6 and 66.Nylon 56 carpet bulked silk is the most aggregated spinning of biofermentation and makes, and Bio-based content reaches 45%, is environmental protection recyclable regenerative nylon.
Detailed description of the invention
Below in conjunction with embodiment, the present invention is further described.
nullUse continuous weighting formula metering device respectively dried bio-based nylon 56 to be cut into slices and color master-batch measures and mixes，Mixture is melted by the screw extruder with heater、Stirring mixing、Metering extrusion，The bio-based nylon 56 that Kai Sai biological industry company limited produces cuts into slices (relative viscosity 2.7-2.95)，Jiangmen city overflow rich fine color masterbatch company limited produce matt master，Melt pipe through being carried out being incubated by high-temperature heat-conductive oil vapour enters spinning pump and precisely measures melt and pressurize，Precisely the melt of metering penetrates through spinneret abnormity spray orifice，Carry out being cooled into as-spun fibre by 270-295 DEG C of constant temperature and humidity air-flow produced by air conditioning system by spinning shaft，Carry out spinning oil by oil nozzle after as-spun fibre boundling to oil，Oil preparation is the BT55 of Da Ke limited company of Germany、BT66 oil preparation，The drawing-off of 2.5-3.0 drafting multiple is carried out through hot-rolling，Entrance converting pipe is carried out expanded being deposited on fiber by 190-205 DEG C of hot compressed air stream and forms curling，And be crimped solidifying to form buiky yarn by drum cooler cooling，Carry out network of yarns knotting through air knotter again and reduce loose，High speed winding head carries out package and forms finished product.The present embodiment uses Germany's knob mug(unit of measure) company S3BCF long filament machine, the bio-based nylon 56 carpet bulked silk produced, fiber number: 1242-1800dtex, strongly: 2.0-2.6cn/dtex, extends: 30-40%.
