Description

The present invention relates to a textile printing fabric and a method for producing the same.

As a textile fabric such as a woven fabric or a knitted fabric, a textile fabric colored by printing is known. Printing fabrics include those in which a paste containing a dye is applied to the surface of a fiber cloth without using a binder resin, or a paste containing a coloring material such as a pigment and a binder resin is applied to the surface of a fiber cloth. ..

A technique for obtaining a textile printing cloth by applying a paste containing a coloring material such as a pigment and a binder resin to the textile cloth is to color the textile cloth in various colors irrespective of the kinds of fibers constituting the textile cloth. It is widely used because it can. In particular, this technique is a preferable technique for obtaining a fiber product that conforms to "ISO 20471", which is an international standard for color, for a fiber cloth having flame retardancy.

However, when the binder resin is applied to the surface of the fiber cloth, the yarns and fibers forming the fiber cloth are constrained by the binder resin, so that the texture of the fiber cloth becomes hard. Therefore, as a countermeasure, it is known to add a softening agent made of silicone oil to a paste containing a binder resin, or to add a softening agent made of silicone oil to a textile fabric after printing. (Patent Document 1).

However, as a result of diligent studies by the present inventors, when a printed fiber cloth is actually produced by applying a coloring material such as a pigment and a binder resin to the surface of the fiber cloth, the obtained fiber cloth is It was found that not only the texture became harder, but also the tear strength decreased.

In such a case, it is possible to use a softening agent such as silicone oil as the finishing resin. However, the softening agent may be added as a finishing resin to the paste containing the binder resin or may be added to the textile fabric after printing. When it is added, the tear strength can be slightly improved, but it cannot be sufficiently improved. In particular, regarding fiber cloths used for work clothes and the like that require strength, it is required to further improve tear strength.

The present invention has been made in order to solve such problems, and provides a textile printing cloth having a binder resin containing a coloring material attached to a textile cloth and having excellent tear strength, and a manufacturing method thereof. The purpose is to do.

The present inventors have made the present invention as a result of extensive studies to solve the above problems.
For example, the present invention is the following (1) to (7).

Have.

(7) Furthermore, in the method for manufacturing a textile printing fabric according to the present invention, the softening agent preferably contains a silicone resin.

According to the present invention, it is possible to obtain a textile printing cloth which has excellent tear strength while having a binder resin containing a coloring material attached to a fiber cloth.

Therefore, the obtained textile printing fabric can be used not only in general clothes, bags, umbrellas, etc., but also in work clothes, particularly high-visibility clothes used in ISO 20471, in applications requiring particularly high strength.

Preferred embodiments of the present invention will be described below, but the present invention is not limited to these aspects, and many modifications can be made within the spirit and scope of the present invention.

The textile printing fabric according to the present embodiment satisfies the requirement of 5.1 color of ISO 20471:2013, and the softening agent is attached to the surface of the fiber constituting at least one surface of the fiber fabric. The binder resin containing the coloring material is attached on the softener.

The material of the fiber cloth useful in the present embodiment is polyester, nylon, aramid, acrylic, modacrylic, rayon such as polyurethane, acetate or viscose, polylactic acid or polyimide, polyphenylene sulfide, fluorine or other chemical fiber, cotton or hemp. It is a natural fiber such as silk or wool, or a mixed fiber, mixed spinning, mixed woven or knitted product of these materials, and is not particularly limited. The fiber cloth made of those materials may be in any form such as woven fabric, knitted fabric or non-woven fabric.

Further, the fiber and the fiber cloth may be those obtained by modifying the polymer constituting the fiber to impart flame retardancy or the like within a range not departing from the intended purpose of the present invention. The spinning resin may be kneaded with a chemical such as a flame retardant (flameproofing agent) or a pigment at the spinning stage, or may be dyed with a dye by post-processing after forming a thread or fiber cloth. It may be processed, flame-retardant (flameproofing), antistatic, antibacterial/deodorant, antibacterial, UV-shielding, or lightproof.

Regarding the coloring of the fiber cloth with the pigment or the dye, even if it is colored so as to meet the requirements for 5.1 colors of ISO 20471:2013, it is colored so as to meet the requirements for the 5.1 colors of ISO 20471:2013. It does not matter whether or not the binder resin containing the coloring material is adhered to the fiber cloth to obtain the target textile printing cloth, and the requirements for 5.1 colors of ISO 20471:2013 should be satisfied. ..

Further, in consideration of the environment in which the highly visible garment using the printing fabric according to the present embodiment is used, it is preferable that the fiber fabric used for the printing fabric according to the present embodiment has flame retardancy. .. As for flame retardancy, it is sufficient if it has flame retardancy according to each application, but in work clothes, it is tested according to ISO 15025:2000 A method (surface flame contact) to ISO 11612 cord letter A1. It is preferable that the defined criteria are met.

The flame-retardant textile printing fabric can be obtained, for example, by using flame-retardant polyester, cotton, rayon or the like as the fibers constituting the fiber fabric. In this case, it is particularly preferable to use flame-retardant aramid or modacrylic fiber.

Further, the fiber cloth in the present embodiment can achieve the intended purpose even if it contains modacrylic fiber having a strength lower than that of polyester or the like. The content of modacrylic fiber in the fiber cloth may be 30% by mass or more, 50% by mass or more, or 70% by mass or more. Further, as the fiber material, modacrylic fiber is used. It may consist of only one.

The textile printing fabric according to the present embodiment is one in which a softening agent is attached to the surface of the fiber constituting at least one surface of the fiber fabric, but the fiber constituting both surfaces of the fiber fabric or the fiber fabric. The softening agent may be attached to all the fibers forming the fiber cloth, including the fibers forming the inside.

The softening agent attached to the surface of the fiber may be a film having a thickness of 1 μm or more, which covers the entire surface of one side of the fiber cloth, but from the viewpoint of the texture and the breathability of the obtained printing cloth, the softening agent is used. It is preferable that the film is less than 1 μm.

Further, as the softening agent useful in the present embodiment, mineral oil, vegetable oil, higher alcohol, synthetic lubricating oil, stearyl group, acetyl group or linear hydrocarbon such as oleyl group or near linear aliphatic hydrocarbon, etc. Surfactants are mentioned, and silicone resin is particularly preferable.

In this case, the silicone resin is not limited to the organopolysiloxane having a three-dimensional network structure, but includes silicone rubber, silicone oil, etc., and can impart flexibility to the fiber cloth. I wish I had it. More specifically, the silicone resin is dimethylpolysiloxane, methylhydrogenpolysiloxane, amino-modified silicone, or the like. From the viewpoint of improving the tear strength, it is preferable to use silicone oil. It is particularly preferable to use amino-modified silicone.

Moreover, the component of the softening agent may be a mixture of a plurality of materials.

Further, in the present embodiment, as a useful color material contained in the binder resin, a material capable of imparting a color satisfying the requirement of 5.1 color of ISO 20471:2013 may be used. As the coloring material contained in the binder resin, for example, pigments, dyes and fluorescent whitening agents are used, and particularly pigments having fluorescence are preferably used.

When the fiber cloth is previously colored using these coloring materials, the colored color is also taken into consideration, and the color is colored to meet the requirements for the 5.1 color of ISO 20471:2013. Further, the color satisfying the requirement for 5.1 color of ISO 20471:2013 is, for example, fluorescent yellow, fluorescent orange red, or fluorescent red, but is not particularly limited and may be any color. Can be colored.

In the present embodiment, the useful binder resin is, for example, a urethane resin, an acrylic resin, a silicone resin, a polyester resin, or a nylon resin, but is not particularly limited, and any resin may be used. You can

In this binder resin, in addition to coloring materials, crosslinking agents, catalysts, deodorants, antibacterial agents, flame retardants, water repellents, softeners, UV absorbers, antioxidants, infrared absorbers, etc. May be added.

In particular, when a binder resin containing a fluorescent pigment is attached to a fiber cloth, a resin liquid containing a fluorescent pigment is used, and this resin liquid preferably contains a crosslinking agent from the viewpoint of durability against washing and abrasion. .. Specific examples of the crosslinking agent include melamine-based crosslinking agents, isocyanate-based crosslinking agents, imine-based crosslinking agents, epoxy-based crosslinking agents, oxazoline-based crosslinking agents, and carbodiimide-based crosslinking agents.

Further, in the case of obtaining a textile printing fabric having flame retardancy, the binder resin containing a coloring material preferably contains a flame retardant from the viewpoint of flame retardancy. As the flame retardant, specifically, a halogen-based flame retardant such as antimony trioxide or hexabromocyclododecane or tris(2,3-dibromopropyl)isocyanurate, or biphenylyl diphenyl phosphate, diphenyl (phenylamide). Examples thereof include phosphoric acid ester amides such as phosphate, and phosphorus-based flame retardants such as naphthyldiphenyl phosphate.

In addition, depending on the target flame retardancy standard, the fibers themselves such as flame retardant rayon, flame retardant cotton, flame retardant polyester, aramid resin, modacrylic resin or polyimide resin contain flame retardant fibers. In the case of using the above-mentioned fiber cloth, it is possible to meet the flame retardancy standard without including the flame retardant in the binder resin containing the coloring material.

The textile printing fabric according to the present embodiment may have a tear strength of 10 N or more in the vertical direction and/or the horizontal direction according to JIS L1096 Tear strength D method Pendulum method, more preferably 13 N, further preferably 15 N. The above is good.

When the tear strength is 10 N or more, the textile printing fabric according to the present embodiment can be preferably used as work clothes or sports clothes.

In addition, the textile printing cloth in the present embodiment is preferably the vertical direction and/or the horizontal direction measured according to ISO 13937-2 trousers method defined in ISO 11612:2015 (standard of fire protection clothing for heat and flame). The tear strength is preferably 10 N or higher, more preferably 13 N or higher, even more preferably 15 N or higher.

Note that these tear strengths are preferably above the respective lower limit values even after washing. In this case, washing was performed 20 times according to JIS L0217 103 method.

Here, the operation and effect of the textile printing cloth in the present embodiment will be described, including the background of obtaining the present invention.

When a softening agent as described above is applied to the fiber for a general textile printing cloth to which a binder resin containing a coloring material is applied, when the binder resin is applied to the fiber cloth after applying the softening agent, the adhesion is achieved. If the binder resin may fall off from the fiber surface due to washing, etc., and if it requires strict color management that meets the requirements for 5.1 color of ISO 20471:2013, it contains a coloring material. Since the idea that the requirements cannot be met with the slight loss of the binder resin, when applying the softening agent to the textile printing fabric, it is possible to apply the softening agent after applying the binder resin to the fiber cloth. It is a normal idea. In addition, as another method, there is an idea that a softening agent is added to a textile printing fabric by blending the softening agent with the binder resin depending on the kind of the binder resin.

However, when a softening agent is added to the fiber cloth and then a softening agent is added to the fiber cloth, or a binder resin containing a softening agent is added to the fiber cloth, the binder resin adheres to the surface of the fiber cloth and the texture of the fiber cloth is Becomes hard. This is because the yarns and fibers forming the fiber cloth are bound by the binder resin.

Moreover, when the softener is added to the fiber cloth after the binder resin is applied or the binder resin containing the softener is added to the fiber cloth, not only the texture of the fiber cloth becomes hard but also the tear strength is increased. I also found that it may drop.

Then, the inventors of the present invention tried to attach a softening agent to the surface of the fiber before applying the binder resin containing the coloring material, and the obtained fiber cloth was found to have a color of 5.1 of ISO 20471:2013. It has been found that the tear strength is significantly improved while satisfying the requirements.

Therefore, even a fiber cloth using modacrylic fiber or the like, which has low strength and is flame retardant, but difficult to be colored in an arbitrary color, satisfies the requirement for 5.1 color of ISO 20471:2013. A printing cloth can be obtained.

Therefore, it is possible to provide work clothes having high visibility, flame retardancy, strength, and flexibility required for working in a dangerous place.

Below, the manufacturing method of the textile printing cloth which concerns on this Embodiment is demonstrated. The present invention is not limited to those manufactured by the following manufacturing method. In addition, a part of the already described contents will be omitted or simplified.

The method for manufacturing a textile printing cloth in the present embodiment includes a step of applying a treatment liquid containing a softening agent to at least one surface of a fiber cloth, and a step of applying a binder resin liquid containing a coloring material to the one surface.

Specifically, first, a fiber cloth is prepared. The fiber cloth may be colored in advance if necessary. In this case, coloring is performed without using the binder resin. The method of coloring a fiber cloth is a cheese dyeing machine, a skein dyeing machine, a Wins type dyeing machine, a jet dyeing machine in the case of a thread shape, a skein shape or a cloth shape, depending on the type and shape of the fibers constituting the fiber cloth. A beam type dyeing machine, a Zicker type dyeing machine, a continuous type dyeing machine, a screen printing machine, an ink jet printer or the like may be used for coloring under conditions such as a dye and a temperature according to the material constituting the fiber cloth.

For example, when a mixed yarn of polyester fiber and cotton is used as the fiber cloth, it may be dyed with a disperse dye and a reactive dye at 60°C to 135°C using a jet dyeing machine.

Further, it may be colored by adding a pigment or the like to the spinning resin at the stage of spinning the fiber. In particular, in the case of aramid fibers, since many of them are colored by adding a pigment in advance at the spinning stage, they may be used as they are as a fiber cloth or may be dyed with a cationic dye.

In the case of modacrylic fiber, a jet dyeing machine or the like may be used for dyeing with a cationic dye.

The color to be colored may be a color that meets the requirements for 5.1 color of ISO 20471:2013, but it is not always ISO color because it is also affected by the color of the resin containing a fluorescent pigment in the subsequent step. It is not necessary to color in a color that satisfies the requirements for 5.141 of 20471:2013.

After coloring the fiber cloth, soaping or heat setting may be performed as necessary.

Next, a treatment liquid containing a softening agent is applied to at least one surface of the fiber cloth. By this step, the softening agent is attached to the surface of the fiber constituting at least one surface layer of the fiber cloth.

The amount of the softening agent in the treatment liquid is preferably 0.01% by mass to 10% by mass. If the amount of the softening agent in the treatment liquid is less than 0.01% by mass, a sufficient effect of improving the tear strength may not be obtained. Further, if the amount of the softening agent in the treatment liquid exceeds 10% by mass, the binder resin containing the coloring material will fall off by washing, and after washing, the requirement for 5.1 colors of ISO 20471:2013 can be satisfied. There is a risk that it may disappear or the necessary flame retardancy may not be imparted. The amount of the softening agent in the treatment liquid is more preferably 0.05% by mass or more and 5% by mass or less.

Examples of the method of applying the treatment liquid containing the softening agent to the fiber cloth include a dip-nip method using a padder, a gravure transfer method using a gravure coater, and a spray method using a spray. By these methods, the treatment liquid containing the softening agent in an amount of 1% to 100% based on the weight of the fiber cloth is applied to the fiber cloth.

The treatment liquid containing the softening agent may be any of an aqueous solution, a dispersion liquid, an organic solvent solution, and an emulsion.

After applying the treatment liquid containing the softening agent to the fiber cloth, it may be dried at about 60°C to 140°C and further heat-treated at 140°C to 230°C if necessary.

In addition, a flame retardant, an antistatic agent, an antibacterial deodorant, a bacteriostatic agent, an ultraviolet absorber, etc. mixed with a treatment liquid containing a softening agent may be added to the treatment liquid containing the softening agent at the same time as the treatment liquid containing the softening agent. It may be added to another liquid before or after being applied to the fiber cloth and then applied to the fiber cloth.

Next, a binder resin liquid containing a coloring material is applied to at least one surface of the fiber cloth to which the treatment liquid containing a softening agent has been applied, and the fiber resin is colored to a color satisfying the requirements for the 5.1 color of ISO 20471:2013. ..

The binder resin liquid containing the coloring material may be any of an aqueous solution, a dispersion liquid, an organic solvent solution, and an emulsion.

Examples of the method for applying the binder resin liquid containing the coloring material to the fiber cloth include a flat screen printing machine, a rotary screen printing machine, an inkjet printer, a knife coater, a kiss coater, and a gravure coater.

A flat screen printing machine or a rotary screen printing machine is preferably used from the viewpoint of coloring the binder resin containing a coloring material on the surface of the fiber without leaving a gap and thinly (less than 20 μm).

In addition, using a flat screen printing machine, a rotary screen printing machine, an inkjet printer, a gravure coater, or the like, the portion of the surface of the fiber cloth to which the binder resin liquid containing the coloring material is applied is colored in a grid or dots. Although a binder resin liquid containing a coloring material may be applied, it is preferable that the binder resin containing a coloring material covers the fiber surface of the printing portion without a gap.

The binder resin liquid containing a coloring material contains, in addition to the coloring material and the binder resin, an ultraviolet absorber, an antioxidant, a crosslinking agent, a catalyst, a deodorant, an antibacterial agent, a flame retardant, a water repellent, an infrared absorbing agent, or , A softener and the like may be added.

In particular, from the viewpoint of obtaining durability that satisfies the requirements for 5.1 color of ISO 20471:2013 against washing and abrasion, the binder resin liquid containing the coloring material contains a crosslinking agent. It is good to have Examples of the crosslinking agent include a melamine-based crosslinking agent, an isocyanate-based crosslinking agent, an imine-based crosslinking agent, an epoxy-based crosslinking agent, an oxazoline-based crosslinking agent, and a carbodiimide-based crosslinking agent.

Further, from the viewpoint of obtaining flame retardancy, it is preferable that the binder resin liquid containing the coloring material contains a flameproofing agent. Examples of flame retardants include halogen-based flame retardants such as antimony trioxide, hexabromocyclododecane and tris(2,3-dibromopropyl)isocyanurate, or biphenylyl diphenyl phosphate, diphenyl (phenylamide) phosphate, naphthyl. Examples thereof include phosphorus-based flame retardants such as diphenyl phosphate.

After applying the binder resin liquid containing such a coloring material to at least one side of the surface of the fiber cloth to which the treatment liquid containing the softening agent has been applied, it is dried and, if necessary, further subjected to heat setting or soaping. Good to do.

As a result, it is possible to obtain a textile printing fabric in which the binder resin containing the coloring material is attached onto the softening agent.

In addition, after applying the binder resin liquid containing the coloring material to the fiber cloth, within a range not departing from the intended purpose of the present invention, flame-retardant processing, antistatic processing, antibacterial deodorization processing, antibacterial processing, ultraviolet shielding processing. The light resistance improving process or the water repellent process may be performed by a dip-nip method or the like.

When the waterproof film is applied, the waterproof film may be applied to one surface of the fiber cloth. However, the binder resin liquid containing the coloring material is applied to only one surface of the fiber cloth so that the binder resin containing the coloring material is added to the fiber cloth. When it is applied to only one surface of the above, the waterproof film may be applied to the other surface of the fiber cloth (the surface to which the binder resin containing the coloring material is not applied).

When a waterproof film is applied to the fiber cloth, the following three methods can be mentioned.

The first method is to apply a resin solution for imparting a waterproof film to the surface of the fiber cloth on which the binder resin containing the coloring material is not applied, by using a pipe coater or the like, and apply the resin solution for imparting the waterproof film. This is a method of applying a waterproof film made of a resin film by immersing the resin liquid in water or the like, coagulating, desolvating and drying the resin liquid.

The second method is to apply a resin solution for applying a waterproof film to the surface of the fiber cloth not containing the binder resin containing the coloring material using a pipe coater, etc., and dry the resin solution to form a waterproof film. It is a method of applying a film.

A third method is to apply an adhesive to the surface of a resin film formed in advance, and to superimpose it on the surface of the fiber cloth on which the binder resin containing the coloring material is not applied, and to bond the fiber cloth and the waterproof film. It is a method of providing a waterproof film by combining them. The resin film to be bonded to the fiber cloth may be a resin film alone, or may be one having a waterproof film formed on release paper or the like. At this time, when the waterproof film laminated on the release paper or the like and the fiber cloth are stuck together, the release paper or the like is peeled off at an arbitrary stage after the fiber cloth and the waterproof film are stuck together. do it.

The resin liquid for providing the waterproof film contains UV absorbers, antioxidants, crosslinking agents, catalysts, deodorants, antibacterial agents, flame retardants, water repellent, as well as binder resin liquids containing coloring materials. Agents, infrared absorbers, or pigments may be added.

Further, when the waterproof film is attached to the fiber cloth with an adhesive, the adhesive also includes an ultraviolet absorber, an antioxidant, a crosslinking agent, a catalyst, a deodorant, an antibacterial agent, a flame retardant, a water repellent, or Infrared absorbers and the like may be added.

After applying the waterproof film to the fiber cloth, drying or heat setting may be performed as necessary.

Further, on the surface of the waterproof film on which the fiber cloth is not laminated, another fiber cloth such as a woven fabric or a knitted fabric may be bonded with an adhesive or the like.

In addition, the fiber cloth with a waterproof film is further subjected to flame-retardant processing, antistatic processing, antibacterial deodorization processing, antibacterial processing, UV shielding processing, light resistance improvement processing, water repellent processing, or soft processing. -Nip method may be used.

The textile printing cloth according to the present embodiment manufactured in this manner has excellent tear strength even though the binder resin containing the coloring material is attached to the fiber cloth, and thus can be used for various products. ..
