Abstract
The invention provides a hydrophilic non-woven fabric with high water absorption and a making process thereof. The required hydrophilic non-woven fabric is prepared from a polypropylene (PP) or polyvinyl chloride (PVC) material serving as a raw material by screw extrusion jet, net formation, rolling with a rolling mill and fabric formation, hydrophilic process and hydrophilic fabric formation. The hydrophilic non-woven fabric produced by using the making process has the advantages of high hydrophilic speed, good softness, handfeel comfortableness and stable hydrophilic performance, and is particularly applied in the fields with relatively high water absorption requirement such as medical treatment and public health.
Description
Technical field
The present invention relates to nonwoven fabric and manufacture technology field thereof, particularly a kind of hydrophilic nonwoven fabrics of high-hydroscopicity and manufacture craft 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 weaving cloth, 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 and is used for making space wadding etc. at present.At some the Application Areas of specific demand is arranged, such as medical and health use cloth, it needs very high water imbibition.In the manufacture craft of the nonwoven fabric of traditional high-hydroscopicity, its main method be take out the nonwoven fabric raw material is soaked a period of time in hydrophilizing agent after, extruding, in large-scale drying room, dry then, flatten moulding at last.This technical process length consuming time, the energy consumption height, complex operation, production efficiency is low; And cause the significant wastage of hydrophilizing agent raw material easily, therefore, it is simple to await proposing a kind of technology, the manufacture craft of the nonwoven fabric that water imbibition is high.
Summary of the invention
At prior art problems, the present invention proposes that a kind of technology is simple, good water absorption, fast hydrophilic nonwoven fabrics and the manufacture craft thereof of absorption speed.
To achieve the object of the present invention, it is raw material that hydrophilic nonwoven fabrics of the present invention adopts polypropylene (PP) or polyvinyl chloride (PVC) material, spray, become net, mill rolls to be pressed into cloth, hydrophilic technology and hydrophilic molding with cloth by the feed screw extruding, finally obtain required hydrophilic nonwoven fabrics.
Wherein, described hydrophilic technology is specially: the pure water that hydrophilizing agent is added 1 to 200 mass ratio stirs into liquid state, heat to 55 ℃, on be coated with (roller is tasted), be dried into cloth by high speed then.Wherein, described hydrophilizing agent is the hydrophilizing agent of the PHP37 model that the American manufacturer makes, and it is to use after the dilution through high purity water again.In concrete the application, according to the specification of nonwoven fabric itself, add 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 ℃-150 ℃, and nonwoven fabric is 100-250 rev/min by the speed of milling train hot-rolling.
Preferably, the mass content of hydrophilizing agent is about 5% in the nonwoven fabric of making by above-mentioned technology.
According to another object of the present invention, the present invention also provides a kind of hydrophilic nonwoven fabrics that utilizes above-mentioned manufacture craft to make.
The hydrophilic nonwoven fabrics that utilizes manufacture craft of the present invention to produce, hydrophilic speed is fast, flexible good, comfortable feel and hydrophilicity are stable, be specially adapted to water imbibition have relatively high expectations such as medicine and hygiene fields.
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 process chart of making hydrophilic nonwoven fabrics of the present invention.
The specific embodiment
In conjunction with the manufacture craft of hydrophilic nonwoven fabrics of the present invention shown in Figure 1, a specific embodiment of the present invention is as follows:
Preparation polypropylene raw material 10000 grams spray raw material by the screw rod extruding, become net, are rolled into cloth with the speed process width 24000-32000mm of 3m/min, the milling train flower roller that temperature is 110-120 ℃ then, through hydrophilic technology, and 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.Finally make the hydrophilic nonwoven fabrics that thickness is 0.2mm.After testing, the wetting-out rate that the hydrophilic cloth that makes is every square centimeter is 2S.
The above only is the preferred embodiments of the present invention; the present invention is not limited to described embodiment; those skilled in the art is not breaking away from spirit of the present invention namely openly in the scope; still can do some corrections or change, so the scope of the present invention is as the criterion with claims restricted portion.
Claims (2)
1. the manufacture craft of a hydrophilic nonwoven fabrics, it is raw material that described nonwoven fabric adopts PP or PVC, it is characterized in that, described manufacture craft comprises: the feed screw extruding sprays, becomes net, mill rolls to be pressed into cloth, hydrophilic technology and hydrophilic nonwoven fabrics moulding, described hydrophilic technology is specially: hydrophilizing agent and pure water are mixed into liquid state by weight 1 to 200, heat to 55 ℃, on be coated with nonwoven fabric, then by being dried into cloth at a high speed, temperature during described milling train roll-in is 110 ℃-150 ℃, and nonwoven fabric is 110-250 rev/min by the speed of milling train hot-rolling.
2. a hydrophilic nonwoven fabrics is characterized in that, described nonwoven fabric is to produce according to the manufacture craft of claim 1, and the mass content of hydrophilizing agent is about 5% in the described nonwoven fabric.
