Abstract
The invention provides a double-color non-woven fabric and a making process thereof. The making process comprises the following steps of: providing a raw material of a first color and a non-woven fabric raw material, stirring, and extruding the raw materials through a first screw; providing a raw material of a second color and a non-woven fabric raw material, stirring, and extruding the raw materials through a second screw; and jetting with double die heads to form a net, performing layered rolling with an integrated rolling mill, performing hot sticking to form a fabric, performing non-woven fabric formation, and finally obtaining the double-color non-woven fabric. The double-color non-woven fabric can solve the problem of single color of the traditional non-woven fabric, the identification capability and the attractiveness of the non-woven fabric in application are increased, and the non-woven fabric has broad market application prospect.
Description
Technical field
The present invention relates to nonwoven fabric and manufacture technology field thereof, particularly a kind of double-colored nonwoven fabric and preparation method thereof.
Background technology
Nonwoven fabric is a kind of fabric that does not need to spin cotton and weave cloth and form, and it is that textile staple or long filament are carried out orientation or support row at random, forms fibre net structure, adopts methods such as mechanical, hot sticky or chemistry to reinforce then and forms.Compare with traditional woven, have that technological process is short, speed of production is fast, output height, characteristics such as cost is low, purposes is wide.Nonwoven fabric is widely used in medical and health use cloth, family decoration cloth, industrial cloth, agricultural fabric etc. at present.Generally speaking, nonwoven fabric all is a single color, in some Application Areas, such as medical field maybe when packing decorate to be used, the aesthetic feeling that needs to increase the recognition capability of nonwoven fabric or increase packing.So, under these situations, need provide a kind of double-colored nonwoven fabric to reach the specific demand of some Application Areas.
Summary of the invention
The present invention is directed to some present Application Areass to the single shortcoming of color that the specific demand of nonwoven fabric and present nonwoven fabric exist, propose a kind of double-colored nonwoven fabric and manufacturing technique thereof.
To achieve the object of the present invention, the manufacture craft of double-colored nonwoven fabric of the present invention comprises: the raw material and the nonwoven fabric raw material mix of first color are provided, carry out the extruding of raw material by first screw rod; The raw material and the nonwoven fabric raw material mix of second color are provided, push by second screw rod; The bimodulus head is injected into net, and unification milling train hot sticky one-tenth cloth of layering roll extrusion and nonwoven fabric moulding finally obtain double-colored nonwoven fabric.
More specifically, the manufacture craft of described double-colored nonwoven fabric is: stir in the raw material of the Masterbatch adding 98% of two kinds of colors of employing, respectively by first, second screw rod, to 210 to the 230 degree melt into liquid states of heating advance the screw rod extruding, the spray silk becomes net, is rolled into cloth by mill rolls pressing one.
Preferably, the raw material of nonwoven fabric of the present invention is polypropylene or polyvinyl chloride.
Preferably, after described milling train is rolled into the step of cloth, also can carry out hydrophilic technology, thereby make the hydrophilic double-colored nonwoven fabric of good water absorption.
Preferably, described hydrophilic technology is meant hydrophilizing agent and pure water is stirred into liquid state with 1 to 200 mass ratio, heat to 55 ℃, on be applied to nonwoven fabric, then by being dried into cloth at a high speed.
According to another object of the present invention, the present invention also proposes a kind of double-colored nonwoven fabric, and it adopts above-mentioned technology to make, and the two sides of described nonwoven fabric is a different colours.
According to a further object of the present invention, the present invention also proposes the double-colored nonwoven fabric of a kind of hydrophily, and it adopts above-mentioned technology to make.
Double-colored nonwoven fabric of the present invention can change traditional single problem of nonwoven fabric color, and recognition capability and aesthetic property have wide market application prospect when increasing the application of nonwoven fabric.
Description of drawings
By the detailed description below in conjunction with accompanying drawing, aforesaid purpose, the feature and advantage with other of the present invention will become apparent.Wherein:
Figure 1 shows that the manufacture craft flow chart of the double-colored nonwoven fabric of one embodiment of the invention;
Figure 2 shows that the manufacture craft flow chart of the double-colored nonwoven fabric of hydrophily of another embodiment of the present invention.
The specific embodiment
In conjunction with the manufacture craft of double-colored nonwoven fabric of the present invention shown in Figure 1, the embodiment of one embodiment of the present of invention is as follows:
Prepare polypropylene raw material 10000 grams, respectively first, second hopper adds different colours Masterbatch mix, then raw material are sprayed by not threaded extruding, become net, unify into cloth, last moulding with the speed process width 24000-32000mm of 3m/min, the milling train flower roller roll-in that temperature is 110-120 ℃ then.The polypropylene that double-colored technology wherein is specially the Masterbatch adding 98% of adopting two kinds of colors stirs, by first and second screw rods, heat to 210 to 230 ℃ and be melt into liquid state respectively, advance the screw rod extruding again, the spray silk, become net, be rolled into cloth by the roll unification, wherein, in concrete the application, according to the specification of nonwoven fabric itself, as thickness, color, the door width of cloth etc. can be produced the double-colored nonwoven fabric of various requirement.
Preferably, the temperature during described milling train roll-in is 110-120 ℃, and nonwoven fabric is 100-250 rev/min by the speed of milling train hot-rolling.
For example, when producing black and white double-colored nonwoven fabric, the pp material of white is provided, pp material with black, the extruding that utilizes bimodulus head screw rod to carry out raw material sprays, becomes net, milling train to be rolled into cloth and nonwoven fabric moulding, finally obtain required double-colored nonwoven fabric, described nonwoven fabric is the two-sided nonwoven fabric of black and white.
In conjunction with the manufacture craft of double-colored nonwoven fabric of the present invention shown in Figure 2, another embodiment of the present invention is as follows:
Prepare polypropylene raw material 10000 grams, respectively first, second hopper adds different colours Masterbatch mix, then raw material are sprayed by not threaded extruding, become net, unify into cloth with the speed process width 24000-32000mm of 3m/min, the milling train flower roller roll-in that temperature is 110-120 ℃ then, pass through hydrophilic technology again, last moulding.Hydrophilic technology wherein is that the hydrophilizing agents with 100 grams add in the high purity waters of 20000 grams, is coated with (roller is tasted) on then, by being dried into cloth at a high speed.The php37 hydrophilizing agent that described hydrophilizing agent adopts the American manufacturer to produce, it is to use through after the dilution of high purity water again.Finally making thickness is the hydrophilic double-colored nonwoven fabric of 0.2mm, and after testing, the wetting-out rate that the hydrophilic double-colored nonwoven fabric that makes is every square centimeter is 2S.
In concrete the application, according to the specification of nonwoven fabric itself, add the hydrophilizing agent and the high purity water of corresponding proportioning as thickness, color etc., can produce the hydrophilic nonwoven fabrics of various requirement.
Preferably, the temperature during described milling train roll-in is 110-120 ℃, and nonwoven fabric is 100-250 rev/min by the speed of milling train hot-rolling.
