Abstract
The invention provides a flame-retardant non-woven fabric and a producing process thereof; the producing process of the non-woven fabric comprises the following steps: blending a raw material and a flame retardant according to a certain ratio, and performing screw extrusion injection, web formation, rolling and fabric formation by a rolling mill, a flame retardation process, and non-woven fabric formation so as to finally obtain a required flame-retardant non-woven fabric. The producing process of the invention directly coats the flame retardant on the non-woven fabric by a flame retardation process according to a specific flow so as to produce a flame-retardant non-woven fabric with stable performance; the process is simple; the production efficiency is high; and no waste of the flame retardant is caused.
Description
Technical field
The present invention relates to nonwoven fabric and manufacture technology field thereof, particularly a kind of flame retardant nonwoven fabric and manufacture craft thereof with excellent fire protecting performance.
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 and is used to make space wadding etc. at present.The base stock of nonwoven fabric is mainly polypropylene (PP), and is light because it is thin, good hand touch; Have porous, good permeability easily keeps cloth cover dry and comfortable; Acid, alkali had excellent durability; And because polyacrylic chemical constitution is insecure, easily degraded also is a kind of environmentally friendly material, therefore, has obtained using widely.But, in some particular application, except general performance, also require nonwoven fabric to have good fire retardant performance, and because the raw material of nonwoven fabric such as polypropylene etc. are hydrocarbon class material, burning easily, after the process of making flame retardant nonwoven fabric is normally flooded a period of time with nonwoven fabric in retardant solution at present, take out oven dry, long flow path and cause the waste of retardant solution easily, so need change the common nonwoven fabric performance of burning easily by new technology, make the good flame retardant nonwoven fabric of a kind of fire line.
Summary of the invention
At prior art problems, the present invention proposes a kind of manufacture craft of flame retardant nonwoven fabric, can produce the good flame retardant nonwoven fabric of fire line.
To achieve the object of the present invention, the manufacture craft of flame retardant nonwoven fabric of the present invention comprises: fire retardant and the raw material of preparing certain proportional quantity, spray, become net, milling train to be rolled into cloth, flame retarding process and nonwoven fabric moulding by the screw rod extruding of raw material then, finally obtain required flame retardant nonwoven fabric.
Preferably, the composition of described fire retardant comprises fire retardant, heat stabilizer, vector resin and auxiliary agent.
Preferably, described flame retarding process is meant described fire retardant added in the high purity water according to certain weight proportion, is coated with nonwoven fabric (roller is tasted) on then, by being dried into cloth at a high speed.
According to another object of the present invention, a kind of flame retardant nonwoven fabric is also proposed, it is to make by above-mentioned manufacture craft.
Preferably, the oxygen index (OI) of described nonwoven fabric is 40～45%.
The present invention directly produces the flame retardant nonwoven fabric of stable performance then by fire retardant is coated with nonwoven fabric on directly according to technological process, technology is simple, the production efficiency height, and can not cause the waste of fire retardant.
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 flame retardant nonwoven fabric 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:
Prepare polypropylene raw material double centner, then raw material being sprayed by screw rod extruding, become net, is that 24000-32000mm, temperature are that 110-120 ℃ milling train flower roller is rolled into cloth with the speed of 3m/min through width then, flame retarding process carries out the nonwoven fabric moulding at last.Wherein, described flame retarding process is that the fire retardants with 100 grams add in the high purity waters of 25000 grams, is coated with (roller is tasted) on then, by being dried into cloth at a high speed.The efficient flame retardant for textile of EPE that described fire retardant adopts Nantong IELTS flame-retarded technology Co., Ltd to produce, its composition comprises fire retardant, heat stabilizer, vector resin and auxiliary agent, finally makes the fire retardant nonwoven fabric that thickness is 0.20mm to 0.50MM.After testing, the fire retardant nonwoven fabric fire resistance that makes is strong, water-tolerant, and processability is good, and less to the mechanical property influence, its oxygen index (OI) is 43.1%.
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 promptly 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 (6)
1. the manufacture craft of a flame retardant nonwoven fabric is characterized in that, described manufacture craft may further comprise the steps: the fire retardant of preparing polypropylene raw material and counterweight, then raw material are sprayed by the screw rod extruding, become net, milling train flower roller is rolled into cloth, flame retarding process carries out the nonwoven fabric moulding at last.
2. the manufacture craft of flame retardant nonwoven fabric as claimed in claim 1 is characterized in that, the composition of described fire retardant comprises fire retardant, heat stabilizer, vector resin and auxiliary agent.
