Abstract
The invention discloses a method for preparing surface storing special-shaped monofilament and relates to a textile fiber production technology. The method is characterized in that a spinneret die with a star-like monofilament spinneret orifice is arranged at the monofilament die orifice of a metering pump, so that monofilaments with star-like surfaces can be spurted from the monofilament die orifice; the monofilaments are mixed and melted by a high-density HDPE (high-density polyethylene) and PP (poly propylene) plastic extruder, and then extruded by the metering pump at the temperature of 250-265 DEG C; the melted and extruded monofilaments are placed in a drawing machine to be drawn after being cooled; the drawn monofilaments are placed in a setting machine to be set and dried; the dried and set monofilaments pass through a glue tank with water soluble polyvinyl alcohol, fertilizer used for cultivating plants or sterilizing or released effective substances for an air purification filter net are mixed in the water soluble polyvinyl alcohol glue; and the dried and glued monofilaments are rolled up in a rolling machine. The monofilaments manufactured by the method can be directly woven into a net or woven into a cultivation net or air purification filter net fabric after being twisted.
Description
Technical field
The present invention relates to textile fabric production technology.
Background technology
The attachment net of sea-plant cultivation, mainly solves and adds fertilizer to waters in traditional cultural method and the problem of seawater pollution that exists; Amino resins is flooded with compared with after fine fibre multifilament and common monofilament retwist, the attachment net through drying and moulding after fertilizer is added in amino resins, the shortcoming of this attachment net be the amino resins that adopts once drying only has surperficial fertilizer can discharge, surperficial fertilizer discharges and completely namely loses reinforced function.
The cleaning filtration screen of air such as air-conditioning discharge sterilization working substance by plastics jointly extrude coated or can not be decomposed resin, glue material cover, once extrude or drying only has function of surface material to discharge, function of surface material is once discharge and completely namely lose function.Above-mentioned condition all needs the problem researching and solving existing monofilament slow-release function.
Summary of the invention
The present invention needs the special-shaped monofilament preparation method being to provide a kind of surperficial storing solved, and solves the little and coating material of existing typical circular monofilament specific area and easily to come off problem.
Technical scheme of the present invention is made up of following processing step: equip at measuring pump monofilament die orifice the spinneret die that a monofilament spray orifice becomes star, directly form the monofilament that surface becomes star when monofilament die orifice is sprayed, the profile of tooth peak heights of the monofilament of ejection is 0.1-0.3 times of filament diameter; With high density HDPE, PP plastic extruder mixed melting that density is 0.955 gram/cc, temperature is 160 DEG C ~ 265 DEG C, then extrudes through measuring pump 250 DEG C-265 DEG C; The monofilament chilling temperature melt extruded is 20 DEG C ~ 40 DEG C, cools total time 6-12 second; Cooled monofilament is put into drawing machine and is carried out drawing-off, and drawing temperature is 90 DEG C ~ 99 DEG C, and drafting multiple is 9 ~ 12 times; Setting machine dryness finalization put into by the monofilament be drawn through, and dryness finalization temperature is 100 DEG C ~ 120 DEG C, dryness finalization time 5-10 second; By a gum box after dryness finalization, become the polyvinyl alcohol glue of adjustable water-soluble speed by commercially available T-330 vinyl acetate and acrylamide copolymer water-soluble poval 90%-95% adding water soluble Polyurethane 5%-10% in gum box, be mixed with the cultivation fertilizer of plant or cleaning filtration screen of air sterilization or release working substance, when going out groove, every root monofilament strikes off surplus glue through the groove close with filament diameter; Then 100 DEG C of-115 DEG C of oven dryings are entered, 15-29 second drying time; By monofilament dried for gluing rolling on winder, filament diameter 0.05mm-1.8mm, monofilament winding tension 80cN-300cN, retracting speed 30m/min-120m/min.The dried direct knitmesh of monofilament of gluing that said method obtains or be made into culturing net or cleaning filtration screen of air fabric after twisting thread.
Outstanding feature of the present invention is by increasing and utilize monofilament surface to amass, giving full play to monofilament surface and store and controlled release working substance; Realize the object having the monofilament net of slow-release function or fabric and energy-saving and cost-reducing production; Solve the little and coating material of existing typical circular monofilament specific area easily to come off problem, cultured output and efficiency can be improved; Reduce function material loss and energy consumption, effectively increase efficiency such as purification function such as plant cultivation usable floor area or filtration etc.As used to the pollution-free food netting gear monofilament net used such as laver, fescue of sea farming, sterilization or release function working substance etc. on the screen pack such as air-conditioning, air purifier that the need of environmental protection aspect use in a large number.China produces various monofilament output more than 30 ten thousand tons at present per year, adopts this monofilament net or fabric can reduce by silk amount more than 50%, not only plastic raw materials 50% capable of reducing using, can economize on coal and electricity simultaneously; And can apply and increase to all specific areas that needs the monofilament net or the fabric product that have slow-release function, there is very large Social and economic benef@.
Accompanying drawing explanation
Fig. 1 is a kind of sectional schematic diagram of special-shaped monofilament gluing of surperficial storing.
Detailed description of the invention
The specific embodiment of the present invention is by following processing step operation:
1. equip at measuring pump die orifice the spinneret die that a monofilament spray orifice becomes star, make monofilament when die orifice sprays, directly form surface and become the monofilament 2(of star see accompanying drawing), the profile of tooth peak heights of the monofilament of ejection is 0.1-0.3 times of filament diameter, spinneret die centre feed hole flow area is 6 ~ 10 times of star silk hole area, and the length of guide hole is monofilament spray orifice length 160%-200%; Monofilament spray orifice length-to-diameter is 6 ~ 10, can reach like this to amass increasing than the monofilament surface of same diameter and be twice above;
2. be high density HDPE, the PP plastic extruder mixed melting of 0.955 gram/cc by density, temperature is 160 DEG C ~ 265 DEG C, then extrudes through measuring pump 250 DEG C-265 DEG C; The monofilament chilling temperature melt extruded is 20 DEG C ~ 40 DEG C, cools total time 6-12 second;
