BACKGROUND OF THE INVENTION
The present invention relates to a product composed of a yarn-like or flocculent fiber material subjected to a radiation graft polymerization treatment.
[0002]
[Prior art]
The radiation graft polymerization method has recently attracted more and more attention as a means for introducing a new functional functional group into an existing polymer molding.
The radiation graft polymerization method is a technique in which a polymer base material is irradiated with radiation to form radicals, and then the monomer is introduced into the base material by reacting with the graft monomer. By irradiating the product with radiation in the presence of a polymerizable monomer, a simultaneous irradiation graft polymerization method in which radical formation and the reaction with the monomer are performed, and the substrate is irradiated with radiation in advance to form radicals, and this irradiation is performed. And a pre-irradiation graft polymerization method in which a used substrate is reacted with a monomer. The pre-irradiation graft polymerization method has an advantage that the amount of a homopolymer which is a by-product is small.
[0003]
Among the pre-irradiation graft polymerization methods, there are a liquid-phase graft polymerization method and a gas-phase graft polymerization method depending on whether the monomer brought into contact with the irradiated substrate is liquid or gas, respectively. Since the liquid phase graft polymerization method can be applied to a wide range of monomers, it has an advantage of versatility.
However, the liquid phase graft polymerization method has the following problems. First, if oxygen is not sufficiently removed at the time of radiation irradiation or graft reaction, it is difficult to perform uniform graft polymerization at a high graft rate, and there is also a problem in the physical stability of the product after graft polymerization. It is. Furthermore, after the graft polymerization, a large amount of washing liquid is required to wash away unnecessary monomers, and there is a problem that the waste liquid treatment is very expensive.
[0004]
In addition, a polyethylene material in which a functional functional group is introduced into a woven or non-woven base material made of polyethylene by using radiation graft polymerization has been disclosed in JP-A-11-279945. Japanese Patent Laid-Open No. 2000-53788 discloses a radiation graft polymerization method for film-like or net-like sheet materials made of styrene or halogenated polyolefin.
[0005]
However, in the prior art, when radiation graft polymerization is performed on cellulosic fibers, there is a problem in that the base material is greatly deteriorated and the texture is deteriorated. Conventionally, there has been a graft polymerization treatment for cotton cloth, but there has been no report on yarn-like or lump-like fibers made of cellulosic fibers such as cotton. Further, in the graft polymerization treatment of the filamentous or fluffy fiber material, the filamentous or fluffy fiber material and the reaction solution cannot be uniformly contacted, and oxygen causing the low graft rate is degassed from the fiber material. It was difficult to do.
Furthermore, a graft polymerization method using a polymerization initiator as a catalyst is known. However, there is a problem that graft efficiency is low and unreacted monomers and a homopolymer obtained by copolymerization of monomers are produced in large quantities.
[0006]
On the other hand, in the commercialization of the fiber material subjected to the graft polymerization treatment, conventionally, since the entire cloth-like cloth was subjected to the graft polymerization treatment, a function was introduced to the entire surface, so that the cost was high. There were problems such as reduced fabric strength and hardened texture. In addition, there has been no report of a fiber product composed of yarn-like or lump-like fibers made of cellulosic fibers such as cotton, to which various functions are imparted by graft polymerization.
Under such a background, the present inventors are composed of a fibrous material into which various functions are introduced by graft polymerization of a polymerizable monomer to a filamentous or flocculent fibrous material using radiation graft polymerization. The present invention relating to a textile product has been completed.
[0007]
[Problems to be solved by the invention]
It is an object of the present invention to provide a fiber product composed of a fibrous material which has been subjected to graft polymerization treatment and has been imparted with various functions without accompanying deterioration of the base material or texture which has been a problem in the prior art. To do. Another object of the present invention is to provide a fiber product to which various functions are imparted at a lower cost than a fiber product composed of a fiber material graft-polymerized on the entire surface of a conventional cloth.
[0008]
[Means for Solving the Problems]
The present invention relates to a textile product using a filamentous fiber produced from a fibrous material in which various functions are introduced by graft polymerization of a polymerizable vinyl monomer to a filamentous or flocculent fibrous material using radiation graft polymerization. It is a problem solving means to configure. The present invention also constitutes a fiber product using a cotton lump fiber material into which various functions are introduced by graft polymerization of a polymerizable vinyl monomer to the lump fiber material using radiation graft polymerization.

That is, the present invention relates to a fiber product composed of a thread-like or cotton lump-like fiber substance into which various functions are introduced by radiation graft polymerization.
In order to introduce a functional functional group into a filamentous or flocculent fiber material using radiation graft polymerization, any method may be used, but in one embodiment of the present invention, the following method can be followed.
[0010]
In one embodiment of the present invention, after a radical is formed by irradiating a filamentous or flocculent fiber material with radiation, the irradiated fiber material is subjected to a graft polymerization reaction treatment containing a polymerizable vinyl monomer in a graft polymerization reaction vessel. A radiation graft polymerization process is performed by impregnating a liquid (hereinafter referred to as a processing liquid).
[0011]
When the fibrous fiber material is subjected to graft polymerization, a cylindrical fibrous material formed body (cheese carrier) formed by winding the fibrous fiber material around a perforated circular tube with a winding machine or the like is used. In addition, when the flocculent fiber material is graft-polymerized, a cylindrical fiber material formed body (loose) formed by arranging a flocculent fiber material inside a cylindrical body having a porous tube at the center thereof. Carrier). The lump-like fiber material may be arranged after the raw cotton is torn to an appropriate size by hand or mechanical force, or may be arranged in a sliver form. The perforated circular tube is open at one end, closed at the other end, and further has a number of holes punched out in a suitable size and shape on the wall of the tube. By introducing the treatment liquid from the open end of the perforated circular tube and ejecting it from the hole, the treatment liquid flows through and contacts the fiber material.

[0015]
The filamentous fiber material when introducing the polymerizable vinyl monomer may be any raw yarn that has not been scoured, after scouring, after bleaching, after caustic mercerization, after ammonia mercerization, or after dyeing. Even if weaving, scouring, bleaching, caustic mercerization, ammonia mercerization, dyeing, and finishing steps are performed after graft polymerization, the function obtained by radiation graft polymerization does not deteriorate. The cotton lump fiber material may also be in any state after raw cotton, after scouring, after bleaching, after caustic mercerization, after ammonia mercerization, or after dyeing.
[0016]
Examples of the polymerizable vinyl monomer that can be introduced into the fiber material by the radiation graft polymerization method of the present invention include a polymerizable vinyl monomer having various functional functional groups, or a secondary polymer after grafting it. A polymerizable vinyl monomer capable of introducing a functional functional group by carrying out the reaction can be used.
[0017]
Monomers having ion exchange groups, hydrophilic groups, hydrophobic groups, antibacterial properties, and monomers capable of introducing functions through secondary reactions include acrylic acid, methacrylic acid, styrene sulfonic acid, vinyl sulfonic acid, methacryl sulfonic acid, Allylsulfonic acid and alkali metal salts thereof, vinylbenzyltrimethylammonium chloride, arylamino, N, N-dimethylaminoethyl acrylate, N, N-dimethylaminoethyl methacrylate, N, N-diethylaminoethyl methacrylate, N, N-dimethyl Acrylamide, N, N-dimethylaminopropylacrylamide, 2-hydroxylethyl methacrylate, acrylonitrile, acrolein, vinylpyridine, styrene, chloromethylstyrene, glycidyl methacrylate, glycidyl acrylate Glycidyl sorbate, glycidyl metaitaconate, glycidyl vinyl sulfonate, ethyl glycidyl maleate, 2-vinyl pyrrolidone, divinyl benzene, 1-vinyl-2-piperidone, N-vinyl-N-methylacetamide, N-vinyl-N -Ethylacetamide, N-vinyl-N-methylpropylamide, N-vinyl-N-ethylpropylamide and derivatives thereof are included.
[0018]
First, the fiber material to be graft polymerized is irradiated with radiation. Irradiation conditions are not particularly limited, but 5 to 200 kGy, particularly 30 to 100 kGy are preferable in a deoxygenated state in order to obtain sufficient graft efficiency. The oxygen concentration may be a concentration at which graft polymerization can be achieved at a required polymerization rate, and is preferably 1% or less, more preferably 100 ppm or less. Examples of radiation that can be suitably used for the purpose of the present invention include, but are not limited to, α rays, β rays, γ rays, electron beams, and ultraviolet rays. A gamma ray or an electron beam is suitable for use in the present invention.
[0019]
After irradiation, the fiber material irradiated with radiation is placed in a graft polymerization reaction vessel. At this time, as described above, the fiber material is arranged as a cylindrical fiber material forming body having a porous circular tube as a center. When performing graft polymerization, it is necessary to deoxidize the fiber material and the reaction vessel. The oxygen concentration may be a concentration at which graft polymerization can be achieved at a required polymerization rate, and is preferably 1% or less, more preferably 100 ppm or less. In one embodiment of the present invention, the inside of a reaction vessel is degassed by using a vacuum pump or the like to reduce the pressure, and then nitrogen is supplied to the reaction vessel to return to normal pressure. By repeating this operation several times, oxygen contained in the reaction vessel and the fiber material is removed. Subsequently, the treatment liquid deaerated in advance by nitrogen bubbling in another container is filled in the graft polymerization reaction container in which the fiber material is arranged. In another aspect of the present invention, an inert gas such as a rare gas can be used in place of nitrogen in order to realize the deoxygenated state.
[0020]
Subsequently, the treatment liquid filled in the reaction vessel is sucked by a pump and circulated so as to return to the treatment tank again through the pump. At this time, it is preferable that the treatment liquid flows through and contacts the fiber material. For example, the processing liquid sucked by the pump from the reaction vessel is introduced into the porous tube at the center of the cylindrical fiber material forming body, and ejected outwardly with respect to the central axis of the circular tube to flow through and contact the fiber material. The reaction solution is sucked so as to flow through the cylindrical fibrous material forming body inwardly in contact with the central axis of the perforated circular tube, and then reacted again through the pump. It may be returned to the container. However, it is preferable that the processing liquid is injected into the cylindrical fiber material forming body with respect to the central axis of the porous circular tube by repeating normal rotation / reverse rotation at regular intervals using a pump capable of normal rotation / reverse rotation. Contact is made by flowing through the fiber material alternately through the holes in the direction or outward. Thereby, a fiber substance can be reliably impregnated with a processing liquid. While allowing the treatment liquid to flow through the fiber material, the temperature of the fiber material and the treatment liquid in the reaction vessel is adjusted to 0 to 100 ° C., preferably 30 to 70 ° C., particularly preferably 40 to 60, by an appropriate heating / cooling means. The radiation graft polymerization treatment is carried out by maintaining the temperature at a temperature of 10 minutes to 6 hours at normal pressure, preferably 30 minutes to 3 hours in a deoxygenated state. When the functional functional group is introduced after the graft polymerization, the functional functional group is introduced into the polymerizable vinyl monomer grafted to the fiber material by performing a secondary reaction using a method known to those skilled in the art. .
[0021]
In an embodiment of the present invention, there is a fiber product composed of a filamentous or fluffy fiber material into which a functional functional group has been introduced using radiation graft polymerization.
By using a fibrous fiber material into which functional functional groups have been introduced by radiation graft polymerization for warp and / or weft of woven fabrics and knitted fabrics, it has higher strength than fiber materials into which functional functional groups have been introduced in the fabric state. It is possible to manufacture them at a low cost. At this time, the fiber material subjected to the radiation graft polymerization treatment may be used for all of the warp and / or the weft, or in combination with the unprocessed one, for example, at a ratio of 1 to 1-20 unprocessed yarns. It may be used. Furthermore, by combining a plurality of filamentous fiber materials having different functions and used as warp and / or weft, it is possible to combine functions that were impossible in the processing of the fabric.
[0022]
Examples of fiber products composed of a fibrous fiber material into which a functional functional group is introduced using the radiation graft polymerization of the present invention include a linen supply sheet, a diaper, a diaper cover, or a collection bag thereof, which has a deodorizing function. Or toiletry products such as toilet seat covers, mats, paper holders, white robes with ammonia deodorization and antibacterial functions, hospital use products such as sick clothes, or socks, acid gas deodorization and basic gas deodorization conflict Examples include, but are not limited to, products with functions. These can be manufactured at a lower cost than the use of a cloth imparted with a function by conventional radiation graft polymerization, and are extremely durable against industrial laundry.
[0023]
In the case of woven fabrics and knitted fabrics, it is possible to produce fiber products having different woven and knitted structures depending on the purpose of use. These examples include textile products such as denim or pants that use yarns that have been functionalized by twill weaving on the skin side, shirts that use yarns that have only been functionalized on the skin side by double weaving. Or, using products with different functions on the front and back, such as pants, etc., or using yarn with a deodorizing function on the skin side, and using yarn with a highly moisture-releasing material on the front side to prevent stuffiness Examples include, but are not limited to, knitted products.
[0024]
The lump-like fiber material into which a functional functional group has been introduced by radiation graft polymerization can be used for batting such as futon and stuffed animals. It can also be used alone to make yarn, but it can be blended with other cellulosic fibers, synthetic fibers such as polyester, polyamide, acrylic, nylon, etc., and raw fibers of animal fibers such as wool and silk. It can also be. Furthermore, various products having functions according to the purpose can be manufactured using these yarns as described above. It is also possible to combine the functions in the form of a cotton lump by blending with a cotton lump-like fiber material into which other functions are introduced.
[0025]
By laminating and coating the surface of the fabric with functional functional groups, waterproofing and water repellency are given to the front side, and functional functional groups are introduced to the back side of the fabric, which is the human skin surface. Therefore, a fiber product having a composite function can be manufactured. Specifically, a waterproof sheet for nursing care that has an ammonia deodorizing function, an apron that has an antibacterial function, a raincoat that has a sweat deodorizing function, an outdoor tent used in camping, and the like.
The following examples illustrate some aspects of the present invention. These examples do not limit the scope of the invention as set forth in the claims.
