Description
Technical Field
The present invention relates to a polyester fiber structure, a method for producing the same, clothing, and bedding.
Background
Polyester fibers are known to have higher hydrophobicity and to be prone to accumulation of sebum and the like than other fibers. This causes other stains to be adsorbed to the sebum-accumulated portion during washing, and black spots (recontamination) are likely to occur. Moreover, accumulation of sebum causes unpleasant odor in addition to recontamination. Skin bacteria such as Moraxella often transfer to the cloth together with sweat, and short and medium chain fatty acids are produced by decomposing sebum, protein and the like, thereby generating unique unpleasant odor.
In order to solve these problems, various fiber structures have been proposed. For example, there are a fluorine-based water repellent having a polyfluoroalkyl group, a fluorine-based stain resistant agent having both a polyfluoroalkyl group and a hydrophilic group (patent documents 1 and 2), and a hydrophilic resin (patent document 3).

Problems to be solved by the invention
However, although the fibrous structure to which the fluorine-based water repellent and the fluorine-based stain repellent are added is difficult to adhere sebum, the fibrous structure may adversely inhibit the removal of stains by washing against stains temporarily adhered. On the other hand, a general substance to which a hydrophilic resin is added greatly improves the cleaning and removing properties of oily soil components. However, when the wearing is repeated in the production of clothes, etc., it is currently impossible to completely remove sebum by washing, and sebum is gradually accumulated, so that stain components such as dust and dirt temporarily removed by washing are adsorbed to the sebum-accumulated portion, thereby causing stain stains, or an unpleasant odor derived from a sebum decomposition product is generated by the sebum and the bacteria in the skin.
The invention provides a polyester fiber structure having anti-redeposition properties and odor-proofing properties against unpleasant odor derived from sebum decomposition products by preventing the accumulation of oily components such as sebum, a method for producing the same, clothing, and bedding.

The polyester fiber structure of the present invention may be a blended product containing fibers other than polyester fibers. Examples of the fibers other than the polyester fibers include cotton, wool, rayon, cuprammonium fibers, nylon fibers, and the like, and the effect of the present invention is particularly remarkable in the case of cotton. They may be included in any form of textile yarns, hybrid yarns, interweaving, cotton, and the like. From the viewpoint of sebum accumulation prevention, the fibers other than polyester fibers may include cellulose fibers such as cotton fibers and rayon, and are preferably 90% by mass or less, more preferably 50% by mass or less, still more preferably 40% by mass or less, and particularly preferably 20% by mass or less.
The fiber structure and the polyester fiber base material of the present invention may be preferably in the form of a woven fabric, a knitted fabric, a nonwoven fabric, or other fabric, and the fibers constituting the fiber structure may be in the form of either short fibers or long fibers, but are not limited thereto.
The difference Δ Lu in the amount of luminescence obtained by the ATP erasure evaluation test before and after the recontamination prevention evaluation test of the fibrous structure of the present invention, which is represented by formula (1) below, is 1000RLu or less, preferably 500 or less, and preferably 300 or less. The lower limit is not limited, and the more Δ Lu is close to 0, the more excellent the antifouling effect and deodorizing effect of sebum stains are exhibited.
ΔLu=Lu(b)-Lu(a) (1)
Δ Lu: difference in Lu value (unit: RLu) before and after the evaluation of prevention of recontamination
Lu (a): evaluation of Lu value (Unit: RLu) of fiber Structure before recontamination prevention test
Lu (b): the fiber structure after the recontamination prevention evaluation test was conducted for the Lu value (unit: RLu).
The Δ Lu value is a luminescence amount derived from a fluorescence reaction of ATP (adenosine triphosphate), ADP (adenosine diphosphate), and AMP (adenosine monophosphate) remaining on the fiber surface obtained by the ATP erasure test (a3 method) before and after the recontamination prevention evaluation test. ATP, ADP, and AMP are one of components contained in sebum, and therefore serve as indicators of the amount of sebum remaining. The recontamination prevention evaluation test and the ATP erasure test (a3 method) are evaluation tests described later.
The fiber structure of the present invention satisfies the above range, so that sebum staining can be reduced, and unpleasant odor and staining derived from sebum staining can be prevented.
From the viewpoint of durability, it is preferable that the performance is maintained even after 50 washes by JIS L0217(1995 year version) 103.
That is, the difference Δ Lu in the amount of luminescence obtained by the ATP erasure evaluation test before and after the recontamination prevention evaluation test performed as shown in formula (1) after 50 washes in the 103 method is preferably 1000RLu or less, more preferably 800 or less, and particularly preferably 500 or less.
For the lower limit, without limitation, Δ Lu is desirably close to 0.
In the present invention, antibacterial processing and the like may be used in combination. Therefore, even if contaminants such as sebum adhere to the fiber structure to decompose the contaminants, the ability of bacteria to decompose the contaminants is less likely to decrease by washing, and this is preferable in that the generation of decomposition products can be suppressed, and the generation of unpleasant odor can be suppressed. The type of the antibacterial agent is not limited, and examples thereof include a pyridine antibacterial agent and a silver antibacterial agent, and among them, a pyridine antibacterial agent is preferable.
The pyridine-based antibacterial agent is not particularly limited, and examples thereof include 2-chloro-6-trichloromethylpyridine, 2-chloro-4-trichloromethyl-6-methoxypyridine, 2-chloro-4-trichloromethyl-6- (2-furylmethoxy) pyridine, bis (4-chlorophenyl) pyridylmethanol, 2,3, 5-trichloro-4- (N-propylsulfonyl) pyridine, 2-pyridylthiol-1-zinc oxide, bis (2-pyridylthiol-1-oxide) and other pyridine-based compounds, N-trichloromethylthiophthalimide, N-1,1,2, 2-tetrachloroethylthiotetrahydrophthalimide, N-trichloromethylthiotetrahydrophthalimide, and mixtures thereof, Halogenated alkylthio compounds such as N-trichloromethylthio-N- (phenyl) methanesulfonamide, N-trichloromethylthio-N- (4-chlorophenyl) methanesulfonamide, N- (1-fluoro-1, 1,2, 2-tetrachloroethylthio) -N- (phenyl) methanesulfonamide, N- (1, 1-difluoro-1, 2, 2-trichloroethylthio) -N- (phenyl) methanesulfonamide, N-dichlorofluoromethylthio-N ' -phenylsulfonamide, N-dimethyl-N ' - (p-tolyl) -N ' - (fluorodichloromethylthio) sulfonamide, 1-diiodomethylsulfonyl-4-chlorobenzene, 3-iodo-2-propargylbutylcarbamic acid, N-trichloromethylthio-N- (4-chlorophenyl) methanesulfonamide, N- (1, 1-difluoro-1, 2-dichloroethylthio) -N- (phenyl) sulfonamide and the like, Organic iodine compounds such as 4-chlorophenyl-3-iodopropargyl formal, 3-ethoxycarbonyloxy-1-bromo-1, 2-diiodo-1-propene, and 2,3, 3-triiodoallyl alcohol, thiazole compounds such as 4, 5-dichloro-2-cyclohexyl-4-isothiazolin-3-one, 2- (4-thiocyanomethylthio) benzothiazole and 2-mercaptobenzothiazole zinc, and benzimidazole compounds such as 1H-2-thiocyanomethylbenzimidazole and 2- (2-chlorophenyl) -1H-benzimidazole.
As a method of containing the antibacterial agent, in addition to a method of post-processing such as treatment in a bath or Pad method, modification of raw yarn kneaded in a fiber, and the like can be considered. However, in the case of raw yarn modification, there is a possibility that physical properties such as yarn strength may significantly change, and therefore, treatment in a bath or treatment by post-processing such as Pad method which does not impair the physical properties is preferable.
The polyester fiber structure of the present invention is not particularly limited as long as it satisfies the conditions specified in the present invention, and a means for producing a fiber structure by a method comprising: a step of preparing a polyester fiber base material; and a step of loading a polyether component having a small molecular weight distribution (variation in molecular weight) on the fiber surface of the polyester fiber structure.
In the above-described exemplary method for producing a polyester fiber structure, a polyester fiber base material is prepared, and a polyether component having a small molecular weight distribution is supported on the polyester fiber base material, but instead of this step, a method of preparing a polyester fiber and supporting a polyether component having a small molecular weight distribution on the surface of the polyester fiber may be employed. In this case, after the loading, the step of forming the polyester fiber structure may be performed using the polyester fiber.
The molecular weight distribution is a numerical value representing a variation in molecular weight, and is determined from a ratio of a polyethylene glycol-reduced weight average molecular weight to a polyethylene glycol-reduced number average molecular weight (weight average molecular weight/number average molecular weight). The Δ Lu value specified in the present invention is satisfied by narrowing the molecular weight distribution, that is, reducing the deviation of the molecular weight. Among them, the use of polyethers having a relatively uniform molecular weight of about 1.00 to 1.35, and among them, 1.00 to 1.25 is preferable from the viewpoint of imparting more excellent recontamination prevention properties. More preferably 1.00 to 1.20.
Further, the polyether component used may have a polyethylene glycol-equivalent weight average molecular weight as large as the Δ Lu value defined in the present invention, and among these, the use of a higher molecular weight polyether such as 1500 to 6000g/mol is preferable from the viewpoint of providing more excellent anti-redeposition properties. More preferably 2000 to 4000 g/mol.
As a method for supporting the polyether component on the fiber surface, in addition to a method of post-processing with a processing agent containing a polyether component by in-bath treatment, Pad method or the like, a method of copolymerizing or graft-polymerizing a base polymer constituting the fiber (the fiber constituting the polyester fiber structure) with a polyether or a copolymerizable monomer having a polyether group, raw yarn modification such as kneading in the fiber, and the like can be considered, but in the case of raw yarn modification, there is a possibility that physical properties such as yarn strength are significantly changed, or dirt easily penetrates into the fiber, and therefore, in-bath treatment which enables selective surface modification without impairing the physical properties, or treatment by post-processing such as Pad method or the like is preferable.
The polyether component in the present invention means a polyether group portion in a polyether or a compound containing a polyether group. The polyether component is a compound having 2 or more ether bonds in an average of 1 molecule, and is a polyether group present in the molecule. Examples of the compound that can be used for supporting the polyether component on the fiber structure of the present invention include polyalkylene glycol, cellulose, and a block copolymer containing polyalkylene glycol and polyester, and the compound is not limited thereto as long as the compound satisfies the requirements of the present invention. Among these, preferred is a polyether ester block copolymer obtained by copolymerizing a block a composed of a polyalkylene glycol unit and a block B composed of a polymer unit copolymerizable with the aforementioned polyalkylene glycol, such as polyester, from the viewpoint of high affinity with polyester fibers and durability such as washing resistance.
The polyalkylene glycol unit constituting the segment a includes preferably a unit derived from polyethylene glycol, polypropylene glycol, polybutylene glycol, and the like, and more preferably a unit derived from polyethylene glycol.
Preferable examples of the polyester unit constituting the above-mentioned segment B include a polymer unit composed of terephthalic acid and/or isophthalic acid and an alkylene glycol.
The copolymerization ratio of the polyester and the polyether of these block copolymers is arbitrary, and from the viewpoint of providing more excellent anti-redeposition properties, the ratio of polyester units to polyether units (mass ratio) =1:1 to 1:30 is preferable. More preferably polyester units to polyether units (mass ratio) =1:1 to 1: 10. More preferably, the ratio of polyester units to polyether units (mass ratio) =1:1 to 1: 3.
The polyester fiber structure of the present invention thus obtained has excellent sebum accumulation prevention properties, and reduces sebum stains and unpleasant odor derived from sebum, and therefore can be suitably used for clothing such as clothing materials for sports wear and the like, or bedding. Examples of bedding include pillow cases, bedspreads, and quilt covers, from the viewpoint of sebum accumulation prevention.

Further, the properties in the examples were measured by the following methods. Next, the present invention will be described in more detail with reference to examples, and the measurement and evaluation in the examples are carried out by the following methods.
