Description

The present invention relates to a fabric having water repellency and excellent pollen adhesion preventing performance.

Pollen allergies, such as sneezing and tears that stop by inhaling pollen such as cedar, rice, ragweed and cypress, are a major social problem.
Since this symptom is caused by inhaling allergen substances such as various pollens, various measures are also being considered for textile products.
For example, a method is known in which pollen or the like is adhered to the surface of a fiber product by applying a slightly adhesive substance to the fiber surface. This is used for screen doors and curtains to prevent pollen etc. from entering the room, and also adheres pollen etc. present in the room to the curtain, etc., reducing the amount of pollen in the room and reducing the amount of human inhalation of pollen. It is a textile product intended to reduce. (Patent Document 1)

  As another pollen countermeasure fabric, a method for preventing pollen from being brought into the house by making pollen difficult to adhere to a coat or the like is known. In this method, a polymer having a (meth) acrylic acid ester having a fluoroalkyl group as an essential polymerization unit is imparted to a fiber fabric having a smooth surface. (Patent Document 2)

  As another pollen countermeasure fabric, there is known a pollen releasing fabric that can be easily dropped even if the pollen adheres to a coat, etc., and can be easily removed after paying at the entrance after returning home. . This is obtained by applying polyethylene glycol 1000 dimethacrylate to the surface of the fiber fabric and performing a low temperature plasma treatment. (Patent Document 3)

  In addition, as another anti-pollen fabric, the antistatic agent is applied to a smooth, specific yarn-use woven fabric to provide antistatic properties to the woven fabric, and the pollen can be applied between the fibers of the woven fabric or in the clothing. Fabrics that are difficult to enter are known. (Patent Document 4)

However, when the fabric imparted with slight adhesiveness described in Patent Document 1 is used for a coat, a jacket, or the like, the touch is poor, and improvement is demanded from the viewpoint of touch as a textile fabric for clothes.
Moreover, in what provided the fluorine-type compound of patent document 2 to the fiber fabric, although pollen is hard to adhere and it is scolding as an effect that it falls easily, pollen is easy to fall off when it hardens. It has not been studied. In recent years, the safety of fluorinated compounds has been discussed, and the development of fiber products using non-fluorinated compounds is also desired.
Moreover, what was described in patent document 3 did not have sufficient effect as a pollen countermeasure.
Moreover, although what was described in patent document 4 contains many of the cloths used for general clothes, there are limitations such as the inability to use fiber cloths using yarns having a single yarn fineness of less than 0.7 dtex. There has been a desire to be able to select fabrics more freely from the viewpoints of fashionability and texture.

In addition, since cedar pollen begins to scatter from around February, a coat or a jacket is often worn when going out, and water repellency is desired for the fiber fabric used for these. However, none of the above-mentioned pollen-preventing fabrics has been studied for water repellency.
Therefore, the present invention provides a water-repellent pollen adhesion-preventing fabric that can be preferably used even when used for apparel, has a good touch, has water repellency, and has pollen adhesion-preventing properties. It is aimed.

In order to solve the above problems, a water-repellent pollen adhesion preventing fabric according to the present invention has the following configuration.
(1) The water-repellent pollen adhesion preventing fabric of the present invention is obtained by imparting a non-fluorinated water repellent and a hydrophilic compound to the fiber surface.
(2) The non-fluorine-based water repellent may be a water repellent made from coconut oil.
(3) The hydrophilic compound may be a polymer or copolymer of a hydrophilic divinyl monomer.

The water-repellent pollen adhesion preventing fabric of the present invention has pollen adhesion preventing performance while having water repellency without using a fluorine compound. Accordingly, it is possible to suppress the pollen from adhering to the clothes and to easily remove the pollen even when the pollen adheres. Moreover, since it has water repellency, when the water-repellent pollen adhesion preventing fabric of the present invention is used for a coat or the like, it can repel rain, prevent the clothes from getting wet, and further suppress the introduction of pollen into the room.
Therefore, the water-repellent pollen adhesion-preventing fabric of the present invention can be preferably used in applications such as coats, jackets, jumpers, windbreakers, hats and gloves that may get wet in the rain.

Hereinafter, the water-repellent pollen adhesion preventing fabric according to an embodiment of the present invention will be described.
The water-repellent pollen adhesion preventing fabric of the present invention is formed by imparting a non-fluorinated water repellent and a hydrophilic compound to the fiber surface.

The fibers of the present invention include synthetic fibers such as polyester, nylon, acrylic, and polyurethane, regenerated fibers such as rayon, bamboo fiber, and soy protein fiber, semi-synthetic fibers such as triacetate and diacetate, cotton, hemp, silk, and hair And natural fibers. In addition, these fibers may be ones in which a plurality of types of fibers are mixed or spun. From the viewpoint of pollen adhesion prevention performance, long fibers are preferably used.
Further, the thickness of the fiber of the present invention is not particularly limited, and a yarn other than 44 to 220 dtex fineness or a single yarn fineness of 0.7 to 8 dtex specified in Japanese Patent Application Laid-Open No. 2003-213541. For example, a yarn having a fineness of 30 dtex, 20 dtex, or 7 dtex, or a single yarn fineness of 0.5 dtex, 0.1 dtex, or 0.01 dtex may be used. Alternatively, a yarn exceeding 220 dtex or a yarn having a single yarn fineness of less than 0.01 dtex may be used.

The water-repellent pollen adhesion preventing fabric may be a woven fabric, a knitted fabric, or a non-woven fabric, and is not particularly limited. From the viewpoint of preventing pollen adhesion, a woven fabric is preferred. Further, these water-repellent pollen adhesion preventing fabrics may be a combination of a plurality of fibers such as union or union, and are not particularly limited.
In addition, the fiber fabric is subjected to processing such as dyeing, printing, softening, antibacterial and deodorizing, antibacterial, SR, hydrophilic, flameproof, waterproof, deodorant, and UV shielding. It may be.

Examples of the non-fluorinated water repellent used in the present invention include paraffinic water repellent, pyridinium salt type such as aluminum stearate, zirconium stearate, stearamide methyl pyridium chloride, stearin such as methylol aramid type and ethylene urea type.

In addition, as the hydrophilic compound of the present invention, those capable of imparting antistatic properties are preferably used.
From the viewpoint of not inhibiting the water repellency of the non-fluorinated water repellent, the hydrophilic compound is preferably a polymer or copolymer of a hydrophilic divinyl monomer.

When a surfactant-based antistatic agent that can be used when using a conventional fluorine-based water repellent is used in combination with a water repellent made from, for example, coconut oil, water repellency is completely lost.
However, by using a polymer or copolymer of a hydrophilic divinyl monomer as described above, a fabric that suppresses the decrease in water repellency and has the ability to prevent pollen adhesion can be obtained.
In particular, a compound in which a hydrophilic divinyl monomer and a vinyl sulfonic acid described below are copolymerized preferably has a water repellency and can further provide a fabric with excellent pollen adhesion prevention properties.

  Examples of the hydrophilic divinyl monomer according to the present invention include divinyl monomers represented by the general formula [I].

Specific examples of vinyl sulfonic acid include 2-acrylamido-2-methylpropane sulfonic acid, 2-alioxy-2-hydroxypropane sulfonic acid, sodium styrene sulfonate, sodium isoprene sulfonate, sulfoethyl methacrylate, sodium allyl sulfonate, Vinyl sulfonic acid monomers such as sodium methacryl sulfonate can be used. In the present invention, two or more of these vinyl sulfonic acid monomers can be used.

In addition, these sulfonic acid groups may be substituted with sodium ions, zinc ions, copper ions, nickel ions, manganese ions, silver ions, iron ions, or the like. In particular, when natural fibers are used as the fibers, the brittleness of the fibers due to strong acids can be suppressed by replacing the sulfonic acid groups. From the viewpoint of preventing embrittlement of the fibers used, it is particularly preferred that the fibers are substituted with sodium ions.
Examples of the hydrophilic compound according to the present invention include 2-acrylamido-2-methylpropanesulfonic acid (AXQ) or sodium 2-acrylamido-2-methylpropanesulfonate as vinyl sulfonic acid, particularly from the viewpoint of polymerization efficiency and pollen adhesion prevention. It is preferable to use a compound having a sulfone group obtained by copolymerizing (AXQ-Na) and the hydrophilic divinyl monomer.

  The water-repellent pollen adhesion preventing fabric of the present invention has a water repellency measured according to a water repellency test (spray test) specified in JIS L1092: 2009 of 2 or more, more preferably 3 or more. If it is less than the second grade, the effect of preventing the wetness of the coat, etc. during rainfall may be insufficient.

Moreover, the pollen adhesion preventing performance of the water-repellent pollen-preventing fabric of the present invention has a “pollen adherence”, which will be described later, of grade 2 or higher, and “ease of pollen” is grade 3 or higher. More preferably, the “difficulty with pollen” is 3rd or higher. In addition, the “ease of pollen” should be 4 or higher.

Also, if the “ease of pollen” is 3rd grade or higher, even if pollen is attached to the fabric that constitutes the coat, etc., the pollen can be easily dropped by paying and the introduction of pollen into the house is suppressed. can do.

Next, the manufacturing method of the water-repellent pollen adhesion preventing fabric according to the present invention will be described in more detail.
Hereinafter, although the process with respect to the textile fabric obtained using a fiber is illustrated and demonstrated, a process is not limited to a thread form, a skein shape, a textile fabric, a knitted fabric, a nonwoven fabric, etc. Any fabric may be used as long as it is included in the concept of the present invention, and the fabric is not limited to the fabric and the following production method.
First, the following treatment liquid is applied to the scoured or dyed woven fabric by a conventional method by a padding method, a spray method, a dipping method, a coating method, or the like.
The treatment liquid is applied to impart a hydrophilic compound to the fiber. The treatment liquid includes the hydrophilic divinyl monomer and vinylsulfonic acid such as 2-acrylamido-2-methylpropanesulfonic acid or a sodium-substituted product thereof. And other polymerizable monomers. Examples of the solvent for the treatment liquid include water, methyl alcohol, ethyl alcohol, isopropyl alcohol, isobutyl alcohol, and a mixture thereof. Water is preferably used. The density | concentration of the hydrophilic compound in a process liquid is 0.05 mass%-50 mass%, More preferably, it exists in the range of 0.1 mass%-10 mass%.

  After the treatment liquid is applied to the woven fabric, heat treatment is performed to fix the hydrophilic compound to the fiber surface. In particular, when the treatment liquid contains a polymerizable monomer, a polymerization reaction is caused to form a polymer or copolymer, and in order to increase the durability of pollen adhesion prevention performance for washing, etc. It is also possible to use this means. For example, dry heat treatment, steam treatment, dipping method, cold batch method, microwave treatment, ultraviolet treatment and the like can be used. These means may be applied singly or in order to increase heating efficiency, for example, microwave treatment or ultraviolet treatment may be used in combination during steam treatment or dry heat treatment. In addition, since it is difficult for the polymerization to proceed in the presence of oxygen in the air, in the case of dry heat treatment, microwave treatment, ultraviolet treatment, it is preferable to treat in an inert gas atmosphere, even in the case of the cold batch method, It is preferable to seal with a sealing material.

  Among these methods, the steam treatment is preferable from the viewpoints of polymerization efficiency and treatment stability. The steam treatment may be normal pressure steam, superheated steam, or high pressure steam, but from the viewpoint of cost, normal pressure steam or superheated steam is preferable. The steam treatment temperature is preferably 80 to 180 ° C, more preferably 100 to 150 ° C. The steam processing time may be about 1 to 90 minutes. In the present invention, preliminary drying may be performed by air drying or a drier before performing the steam treatment or the like.

A radical polymerization initiator can be added to the treatment liquid used in the present invention. For example, inorganic polymerization initiators such as ammonium persulfate, potassium persulfate, hydrogen peroxide, 2,2′-azobis (2-amidinopropane) dihydrochloride, 2,2′-azobis (N, N′- Organic polymerization initiators such as dimethyleneisobutyramidin) dihydrochloride and 2- (carbamoylazo) isobutylnitrile can be used. Further, a water-insoluble polymerization initiator such as benzoyl peroxide or azobisisobutylnitrile may be used by emulsifying with a surfactant such as anion or nonion. A redox polymerization initiator may be used.
Moreover, you may add other compounds, such as a crosslinking agent and penetrant which have acrylic acid, methacrylic acid, N-methylol acrylamide, an aziridine group, an ethyleneimine group, and a carbodiimide group, to the process liquid used for this invention. A non-fluorinated water repellent may also be included.

The fabric after the heat treatment is preferably soaped as necessary to remove unfixed components contained in the treatment liquid. The soaping may be only water, but may contain an alkali agent, a surfactant, or the like. Further, it may be cold water or hot water of about 40 to 90 ° C.
In addition, before or after the treatment liquid is applied to the fiber surface, the fabric is dyed, printed, softened, antibacterial and deodorized, antibacterial, SR processed, hydrophilic processed, flameproofed, waterproofed, disinfected. Processing such as odor processing and ultraviolet shielding processing may be performed. Moreover, you may perform a calendar process, a tumbler process, etc.

  The amount of the hydrophilic compound applied to the fiber is about 0.01% by mass to 40% by mass, more preferably 0.1% by mass to 10% by mass with respect to the mass of the fiber. When the amount is less than 0.01% by mass, there is a possibility that the pollen adhesion preventing performance is not sufficient. On the other hand, if it exceeds 40% by mass, the resulting water-repellent pollen adhesion preventing fabric may have a hard texture or may not be able to exhibit sufficient water repellency.

After imparting a hydrophilic compound to the fiber surface, a non-fluorinated water repellent can be imparted to the fiber surface to which the hydrophilic compound has been imparted. The above-mentioned thing can be used for a non-fluorine type water repellent.
The non-fluorinated water repellent can be applied to the woven fabric by a padding method, a spray method, a coating method, or the like, with a treatment liquid containing the non-fluorinated water repellent. Examples of the solvent for the treatment liquid include water, methyl alcohol, ethyl alcohol, isopropyl alcohol, isobutyl alcohol, ethylene glycol, propylene glycol, mineral spirits, and a mixture thereof. Water is preferably used. The density | concentration of the non-fluorine type water repellent in a process liquid is 0.01 mass%-20 mass%, More preferably, it exists in the range of 0.1 mass%-10 mass%. If it is less than 0.01% by mass, sufficient water repellency and pollen adhesion prevention may not be achieved. On the other hand, if it exceeds 20% by mass, the texture may become hard or chalk marks may be generated.
After the treatment liquid is applied to the fabric, heat treatment is performed. The heat treatment is preferably performed at about 60 to 120 ° C. for about 10 seconds to 5 minutes, and then at about 130 to 160 ° C. for about 10 seconds to 2 minutes.
In addition, a crosslinking agent such as isocyanate, melamine, aziridine, ethyleneimine, and carbodiimide, a catalyst, a softening agent, a penetrating agent, and the like may be added to the treatment liquid containing a non-fluorinated water repellent.

The amount of the non-fluorinated water repellent applied to the fiber is about 0.01% by mass to 20% by mass, more preferably 0.1% by mass to 10% by mass with respect to the mass of the fiber. If the amount is less than 0.01% by mass, there is a possibility that sufficient water repellency may not be obtained. On the other hand, if it exceeds 20% by mass, the texture of the water-repellent pollen adhesion preventing fabric obtained may become hard or chalk marks may be generated.
A calender treatment or the like may be performed after heat-treating the woven fabric to which the non-fluorinated water repellent is applied. The calendering process is preferable from the viewpoint of preventing pollen adhesion because it smooths the surface of a fabric or the like and also reduces the gap between fibers.

  In addition, the above manufacturing method is to separately impart a hydrophilic compound to a fiber and impart a non-fluorinated water repellent, but add a non-fluorinated water repellent to the treatment liquid containing the hydrophilic compound. Alternatively, a hydrophilic compound is added to a treatment liquid containing a non-fluorine-based water repellent, a treatment liquid containing these is added to the fabric at once, and a hydrophilic compound and a non-fluorine-type water repellent are applied to the fiber surface. May be. Thus, when providing a hydrophilic compound and a non-fluorine-type water repellent simultaneously, what is necessary is just to employ | adopt the conditions similar to the heat processing for adhering the hydrophilic compound mentioned above to the fiber surface as heat processing conditions.

As described above, the water-repellent pollen adhesion preventing fabric of the present invention is formed by imparting a non-fluorinated water repellent and a hydrophilic compound to the surface of the fiber, and constitutes a yarn, a woven fabric, a knitted fabric, and a non-woven fabric. It is preferable from the viewpoint of pollen adhesion prevention performance and water repellency that non-fluorinated water repellents and hydrophilic compounds are applied to all fiber surfaces, but it is necessary that these materials be necessarily applied to all fiber surfaces. However, the obtained water-repellent pollen adhesion-preventing fabric only has to have the pollen adhesion-preventing performance and water-repellent performance of the present invention.
Further, the non-fluorinated water repellent and the hydrophilic compound may be present not only on the surface of the fiber but also inside the fiber.
The water-repellent pollen adhesion-preventing fabric of the present invention has pollen adhesion-preventing performance while having water repellency, so various kinds such as coats, jumpers, windbreakers, ski wear, snowboard wear, goggles, gloves, hats, etc. Can be used for things.
