Description of the Related Art Conventionally, a method of flame-retarding a synthetic fiber made of a polymer such as polyester or polyamide is, for example, a method of blending a halogen- or phosphorus-containing flame retardant with the polymer and then forming a fiber. The method of flame-retarding after conversion is mainly known.

定している。However, in the former blending method, the physical properties of the obtained fiber are deteriorated by the addition of the flame retardant and the flame retardant is used, for example, during washing while using the fabric product made of such fiber. Has a drawback that it gradually elutes and the flame retardancy decreases. In the polyethylene fiber nonwoven fabric which is the object of the present invention, there is no disclosure of a satisfactory flame retardant method for such a blending method, and even if the present inventors attempt flame retardation by such a method. It is presumed that the same problem as in the case of the synthetic fiber is caused.

推察している。In the latter method of flame-retarding after fiberization, the flame-retardant used for the processing is not sufficiently secured to the fiber for holding and the fabric made of the processed fiber has poor washing resistance. Has the drawback of. The present inventors presume that even if such a method is applied to a polyethylene fiber non-woven fabric, the same problems as those of the synthetic fiber may occur.

Proposals have also been made. For example 1-20
In 268 or JP-A-5-163673, such a flame-retardant post-processing method is proposed in which the former is applied to a material for clothing in which cellulose fibers and cellulose fibers are mixed with polyester fibers, and the latter is used for polyester.

I can't find what is proposed. Even if the inventors of the present invention were able to secure flame-retardant performance by applying such a post-processing method to the polyethylene fiber, the physical properties of the polyethylene fiber would be particularly strongly deteriorated, and it would be difficult to secure practical performance. thinking.

Vinyl phosphonate oligomers, which are easily available as AKZO Co., Ltd., etc., and these can be suitably used in the present invention.

他に特別の利点が得られ難いからである。According to the present inventors, it is difficult to achieve the object of the present invention even if an auxiliary agent for VPO other than the specific acrylates is used. In the present invention, the concentration of VPO in the flame-retardant working liquid of the present invention needs to be at least 10% by weight. VPO concentration in flame retardant processing liquid is 10
When it is less than wt%, the drying energy in the drying step after treating the PE non-woven fabric with the flame-retardant processing liquid becomes large,
This is because it is difficult to obtain other special advantages.

好ましい。Further, as the concentration of the flame-retardant working fluid is increased, the viscosity of the working fluid is increased and the solubility of the specific acrylates to be coexistent with VPO is lowered, which makes it difficult to form a uniform working fluid. The upper limit of the VPO concentration in the flame-retardant processing liquid in the present invention is 60% by weight. Therefore, the VPO in the flame-retardant working liquid in the present invention is 10 to 60.
It is preferably in the range of 30% by weight and particularly preferably in the range of 30 to 50% by weight.

かむしろ悪影響が認められるようになるからである。The specific acrylates in the present invention must be 2 to 10% by weight of the amount of VPO in the flame retardant processing liquid. If it is less than 2% by weight, it is almost impossible to expect the durable flame retardant effect intended by the present invention in the obtained PE nonwoven fabric, and if it exceeds 10% by weight, a special effect commensurate with the increase in the amount is obtained. This is because not only will it be impossible to do this, but rather adverse effects will be recognized.

It is preferred that The method for adhering the flame-retardant processing liquid of the present invention to the PE non-woven fabric may be, for example, a method using a gravure roll, a method using a coating machine, a method using a spray, or the like. A method of immersing a PE non-woven fabric in a flame-retardant processing liquid and then squeezing with a roll in a spread state, that is, a pad method is particularly preferable. After squeezing, it is preferable to dry with a pin tenter, a short loop or the like. Although the drying temperature and the drying time depend on the air volume, 60 to 120 ° C. and 2 to 10 minutes are suitable.

Is a solvent of. The PE non-woven fabric to which the flame-retardant processing liquid is attached is then introduced into the electron beam irradiation device. At this time, it is preferable to irradiate in a nitrogen stream in order to avoid a polymerization obstacle due to oxygen of VPO. The accelerating voltage of the electron beam in the present invention is preferably 50 to 800 KV, though it depends on the density and thickness of the PE nonwoven fabric. If the density of the PE non-woven fabric is high and thick, the electron beam accelerating voltage is not increased in order to completely reach the inside of the PE non-woven fabric or the surface opposite to the surface irradiated with the electron beam, so that the PE non-woven fabric is If the density and thickness are low, it is economical to lower the acceleration voltage. If the electron beam does not reach the side opposite to the side where electron beam irradiation is performed, perform electron beam irradiation from one side, then
Electron beam irradiation may be performed from the other side. As a specific example, thickness, 0.2 mm, density, P of 0.25 g / cm 3
In the case of E non-woven fabric, it is preferable to irradiate the electron beam from one side with an acceleration voltage of 100 to 200 KV.

d. Even with such a low electron beam dose,
According to the present invention, VPO can be adhered to a PE non-woven fabric so as to achieve the object of the present invention. When the electron beam irradiation dose is 1 Mrad or less, even if TMPTA or TMPTMA is added, the VPO fixing rate is surprisingly low, which is inconvenient to obtain the required flame retardancy. When it is 30 Mrad or more, the physical properties of strength are seriously deteriorated, which is contrary to the purpose of the present invention.

る。EFFECT OF THE INVENTION When the irradiation dose of electron beam is increased to obtain a high VPO adhesion rate to a PE non-woven fabric, the burst strength of the PE non-woven fabric is lowered and it becomes unusable. A proper amount of T which is a specific acrylate
By using a flame-retardant processing liquid containing MPTA or TMPTMA, a flame-retardant PE that has a high VPO fixation rate and excellent wash resistance at an electron beam irradiation dose that does not substantially reduce the burst strength of the PE nonwoven fabric. Non-woven fabric can be obtained.
