Description

 Specification

 Textile material for post dyeing

 Technical field

 [0001] The present invention relates to a fiber material having improved dyeability when post-dying.

 Background art

 [0002] Used in conventional textile products! /, Ru, water repellent functional processing, oil repellent functional processing, flexible processing, antifouling processing, anti-pilling processing, etc. After dyeing woven fabrics and non-woven fabrics, they are processed with resin, then sewn, and commercialized as clothing, bags, hats, and sports clothing. In addition, yarns are also processed into products after dyeing, after being added to knitted fabrics and fabrics.

 [0003] A method of manufacturing a fiber material through such a process is excellent in that a product with a stable quality is manufactured in large quantities. In today's era where consumer preferences change rapidly, it is most important to shorten product delivery times, and manufacturers will consider consumer needs such as colors, sizes, materials, and patterns. It was too time consuming to manufacture the products desired by consumers in a timely manner by using conventional manufacturing methods such as thread manufacture, fabric manufacture, dyeing, resin processing, and sewing after grasping. It is impossible to supply to the market.

 [0004] In particular, for trendy products, even if consumer-oriented information is obtained at the store, which has a short sales period that can be placed at the store, if the sewn product whose color, size, and pattern are already in stock is stocked, Anything that doesn't suit your taste will be a bad stock. On the other hand, if you try to change the plan during the sales period in response to your needs, you will miss the business opportunity.

[0005] For this reason, product dyeing is performed after product completion to meet short delivery times, but color management is particularly important for plant fibers such as cotton and hemp and regenerated fibers such as rayon. Is not stable, can cause scratches and wrinkles, can easily cause uneven dyeing, and can hardly perform durable water-repellent or oil-repellent treatment after dyeing. The water-repellent finish is limited to the degree of application of the water-repellent spray after dyeing. I couldn't. Synthetic fibers and semi-synthetic fibers, when subjected to water- and oil-repellent finishing after normal dyeing or product dyeing, decrease the friction fastness, especially in polyester microphone fiber materials. Power, ivy.

[0006] On the other hand, Patent Document 1 describes a post-dyed fabric that can be processed into a fabric material that is not dyed to obtain a fabric having a necessary color and design by post-dying. Yes. This is because fiber products made of synthetic fiber, semi-synthetic fiber, regenerated fiber, natural fiber, etc. are pre-formed in the form of woven fabric, knitted fabric, non-woven fabric, etc., and a synthetic resin film is formed on the surface by a laminating method, etc. This improves the dyeability of post-dying.

 [0007] Patent Document 1: Japanese Patent Application Laid-Open No. 2002-105865

 Disclosure of the invention

 Problems to be solved by the invention

[0008] However, in the method of Patent Document 1, since a synthetic resin film is formed, the object to be processed is limited to a fabric. In addition, it is necessary to use an adhesive to bond the synthetic resin film, and there has been a problem that the resulting fiber product has insufficient water repellency, washing resistance, and the like.

 [0009] Even if the water repellent is used in advance before dyeing, the water repellent will fall off during the dyeing process just by reducing the dyeability. The later fiber material has almost no water repellency. For this reason, it has been considered that post-dyeing after water-repellent processing is virtually impossible. On the other hand, when water-repellent processing is performed after dyeing, there is a problem that the fastness is reduced by this heat that needs to be baked for durability.

[0010] Furthermore, even when normal dyeing is performed instead of post-dyeing, the fibers are often damaged during the dyeing process. For example, the yarn for knitting may cause fluffing, and the surface is easily whitened by washing with a washing machine after sewing. In the composite material of plant fiber and animal fiber, there is a problem that sufficient pretreatment cannot be performed due to severe damage to the animal fiber, which uses alkali in the preparation process required before dyeing process, Even with the dyeing process itself, it was difficult to dye the animal fibers in a dark color without damaging them. Also, because it is a composite fiber, the dye used is effective for both materials As a result, the dyeing process took longer and the damage to the fiber material was even greater. Recycled fibers such as rayon could not be made durable due to severe damage during dyeing and a decrease in strength, and severe damage in washing tests after dyeing.

 [0011] Furthermore, in the sizing process of spun yarn, starch, PVA, and acrylic glue are applied to the warp so that the warp is not damaged during weaving. For fabrics woven using the spun yarn, Since a large amount of glue is attached, it is necessary to remove it with a large scouring desizing machine at the dyeing processing plant, resulting in a large burden on capital investment, energy use, wastewater treatment, etc.! /

 [0012] And it has been known that even in the product obtained by the conventional method of resin processing after dyeing, deterioration of texture, surface whitening phenomenon, occurrence of pilling, reduction in strength, etc. occur in the washing process. . For this reason, if the dyeing process, which is more severe than the conditions for washing, is performed after resin processing that improves water repellency, oil repellency, and flexibility, it is difficult to maintain these functions. I thought it was! /

 [0013] Therefore, the present invention can be applied not only to fabrics but also to all fiber materials, and even if post-dyeing is performed, the fibers are difficult to be damaged and the dyeability after dyeing is further increased. Accordingly, an object is to provide a fiber material for post-dyeing having high water repellency, oil repellency, and washing resistance.

 Means for solving the problem

 [0014] The present invention provides a fiber material having at least one functional group among a hydroxyl group, an amino group, an amide group, a carboxyl group, and a urethane group with a functional group that binds to the functional group of the fiber material. The above-mentioned problems have been solved by including a resin solution containing as a main component a synthetic resin that improves the dyeability of the fiber material and binding the molecules of the synthetic resin to the molecules of the fiber material. . In other words, by combining a synthetic resin as a molecule with the functional group of the fiber material, the synthetic resin that exhibits water repellency and oil repellency, etc., which improves the dyeability simply by the presence of the synthetic resin, is used in the subsequent dyeing process. For example, it was made difficult to peel off from the fiber material.

[0015] The shape of the fiber material bonded to the synthetic resin according to the present invention is not particularly limited. More specifically, it can be used for cotton, sliver, filament yarn, spun yarn, sewing yarn, woven fabric, knitted fabric, non-woven fabric, or a sewing product made of these. Examples of the fiber material having the above functional group include paper fiber, bamboo fiber, cotton, hemp, rayon, cellulose fiber obtained by an organic solvent spinning method, copper ammonia rayon, silk, wool, polyester, aliphatic. Examples thereof include aromatic polyamide fibers such as polyamide fibers and aramid fibers, polyurethane, diacetate, triacetate, and composite fibers using a plurality of these.

 [0016] As a method of binding the molecule of the synthetic resin and the molecule of the fiber material, a crosslinking agent that binds a functional group of each molecule is included in the resin solution, and each molecule is bound by the crosslinking agent. The method of combining is mentioned. As such a crosslinking agent, an isocyanate compound having a plurality of isocyanate groups can be used.

 [0017] In particular, when the synthetic resin includes a copolymer resin composed of an acrylate unit having a perfluoroalkyl group and a hydrophilic butyl monomer unit, it is hydrophilic and hydrophobic. Because it has both a part and a perfluoroalkyl group in water, it exhibits water repellency and oil repellency to repel dirt, and in water the hydrophilic end of the bull group comes out on the surface and exhibits hydrophilicity. And demonstrates the effect of removing dirt. In addition, since there is a hydrophilic group, it is possible to improve dyeability and hygroscopicity in particular.

 [0018] Further, when the synthetic resin is added to the copolymer resin, a perfluoroalkyl acrylate resin, a polyester resin, a silicone resin, a urethane resin, or the like that does not have a hydrophilic group is added to each of the added resins. Combined effects can be imparted. A perfluoroalkyl acrylate resin improves water repellency, and a silicon resin improves strength and flexibility in a bath. When polyester resin or urethane resin is included, it can be made into a fiber material with a characteristic texture for each resin.

[0019] The fiber material for post-dyeing combined with the above synthetic resin can have an oil repellency resulting from the oil repellency test described in AATCC118-2002, which can be at least second grade, and can be improved up to grade 7 I can do it. In addition, the water repellency result according to the water repellency test described in JIS L 1092 can be at least grade 2, and can be improved up to grade 5. The invention's effect [0020] The post-dyeing fiber material, which is effective in the present invention, enables post-dyeing not only for fabrics but also for all textile products. In addition, any fiber that has a functional group that reacts can be used, so many fiber materials can be post-dyed, and damage that may occur during the post-dyeing process or after dyeing can occur. Can be suppressed. As a result, when manufacturing and shipping products made of fiber materials, it is possible to easily dye in the dyeing process adjacent to the sewing base, and it is possible to ship products after dyeing in a short period of time according to market trends. As a result, it is possible to reduce the loss of sales opportunities and to prevent unsold products.

 [0021] The fiber material that can be post-dyed is a fiber with low surface tension that has high washing resistance, water repellency, and oil repellency because a synthetic resin that enhances dyeability is bonded to the fiber material through molecules. It becomes a material. This eliminates the need for water-repellent spraying, which was conventionally performed after product dyeing, and allows easy dyeing. In addition, the fiber material is resistant to oil stains. In addition, the synthetic resin having enhanced dyeability makes the fiber material excellent in hygroscopicity. This hygroscopicity can be compatible with water repellency. Furthermore, since it is combined with synthetic resin, the durability of the fiber material itself is increased, and the fiber material becomes damaged when dyeing compared to conventional fiber materials. As a result, in the case of spun yarn, there is no need to protect the yarn by performing sizing processing, which has a large burden of desizing after weaving.

 BEST MODE FOR CARRYING OUT THE INVENTION

 Hereinafter, the present invention will be described in detail. According to the present invention, a fiber material having at least one functional group among a hydroxyl group, an amino group, an amide group, a carboxyl group, and a urethane group is bonded to the functional group of the fiber material so as to increase the dyeability of the fiber material. A fiber material for post-dyeing, which includes a resin solution containing a synthetic resin to be improved as a main component and binds molecules of the synthetic resin to molecules of the fiber material. Here, to improve the dyeability means to obtain a product with a higher density and density under the same conditions. For example, the density of the dye can be determined by, for example, the light absorption coefficient K and scattering. It is expressed as a K / S value that is the ratio to the coefficient S.

[0023] The fiber material that can be post-dyed in the present invention is not particularly limited in shape, but is made of raw materials and yarns such as cotton, sliver, filament yarn, spun yarn, sewing yarn, woven fabric, knitted fabric, or Fabrics such as non-woven fabrics and sewing products made of these fabrics and threads Even in a state of deviation, post-dyeing can be made possible.

 [0024] Examples of the fiber material include vegetable fibers such as paper fiber, bamboo fiber, cotton and hemp, rayon, cellulose fiber obtained by an organic solvent spinning method, regenerated fiber such as copper ammonia rayon, silk Animal fibers such as wool, polyester, polyurethane, aliphatic polyamide fiber ½—nylon, 6, 6—nylon. ), Synthetic fibers such as aromatic polyamide fibers, and semisynthetic fibers such as diacetate and triacetate. Specific examples of cellulose fibers obtained by the organic solvent spinning method include tencel and lyocell (both are registered trademarks), and copper ammonia rayon is a registered trademark of Bemberg and Cubula (both are registered trademarks). ).

 [0025] Of these fiber materials, plant fibers, regenerated fibers, and diacetates have hydroxyl groups, and polyesters also have hydroxyl groups at the ends. Polyamide fibers and animal fibers have amino groups, carboxyl groups, and amide groups. The terminal of the polyester has a carboxyl group, and nylon has an amide group. Furthermore, the polyurethane fiber has a urethane group at the end. In addition, triacetate theoretically has the ability to change all hydroxyl groups to acetyl groups. Actually, some hydroxyl groups remain, and these hydroxyl groups react.

 [0026] Among these, polyester fibers, in particular, have been difficult to impart moisture permeability and water repellency, not only dyeability, with conventional methods. By combining a synthetic resin, moisture permeability can be easily provided, and by combining other synthetic resins, water repellency can be easily provided.

 [0027] Prior to bonding the synthetic resin to these fiber materials, scouring, bleaching, desizing and the like are preferably performed because the synthetic resin is bonded and the quality is immediately stabilized.

[0028] Specifically, in scouring, impurities adhering to the fiber material can be removed so that the synthetic resin can be easily bonded. Cotton contains natural contaminants such as natural wax pectin, which can be removed by high-temperature alkali or detergent treatment at high temperatures. In the case of blending and weaving of cellulose and animal fibers such as cotton / wool, animal fibers will be dissolved if alkali is used, so scouring with an acidic solution. Synthetic fibers are free of contaminants, but the oil used during the process is adhered to them, so they are removed using detergent at high temperatures. [0029] Bleaching is performed mainly on cotton materials. There are a chlorine method and a hydrogen peroxide method, and it is preferable to use the hydrogen peroxide method from an environmental viewpoint. In this method, hydrogen peroxide and alkali are used in combination, but in the case of fiber materials containing animal fibers such as wool, the fiber is melted and bleaching is performed with the alkali used as low as possible.

 [0030] The desizing is performed to prevent warp from being damaged when a cotton yarn or a cotton composite spun yarn (including rayon, cellulose fiber obtained by an organic solvent spinning method, hemp) is used as a woven fabric. A sizing process to apply glue, but to remove this glue. In the case of 100% cotton, a high concentration of alkali and an oxidizing paste remover are used in combination, and treatment is performed at a high temperature for a long time. Cellulose fibers obtained by rayon and organic solvent spinning methods are susceptible to damage when treated for a long time with a high concentration of alkali. Remove. In the case of cotton / wool, etc., the paste is removed by the enzymatic method without using an alkaline agent as in the case of rayon. Synthetic fibers such as polyester do not require sizing, so no desizing is necessary. For knitting

No sizing! / No desizing required.

[0031] The synthetic resin to be bonded to the functional group of these fiber materials preferably contains a copolymer resin composed of an acrylate unit having a perfluoroalkyl group and a hydrophilic butyl monomer unit. Among these, the presence of the hydrophilic butyl monomer unit improves the dyeability by increasing the affinity with the dye. Such a copolymer resin may be one obtained by simply mixing and copolymerizing the monomers as the units! /, And the block copolymer that is bonded after the respective monomers are polymerized. It may be a coalescence.

[0032] The attalylate unit having a perfluoroalkyl group may be an ester unit having a structure in which a perfluorinated alkyl group is bonded to an acrylic acid unit! /, But between the perfluoroalkyl group and the acrylic group. In addition, when the ester unit has a polyalkylene ether chain and has a structure as shown in the following chemical formula (1), the effects such as water repellency are more excellent.

[0033] [Chemical 1] One (One CH ₂ — CH—) _m —

 I ")

〇 = C 1 O— (CH ₂ ) _D — O— (CF ₂ ) _n -CF 3

 (m, n, p are natural numbers)

[0034] Examples of the hydrophilic butyl monomer unit include, for example, a butyl alcohol unit and an acrylate ester unit having a hydrophilic group in the ester moiety. In the case of using a butyl alcohol unit, for example, after copolymerization using butyl acetate, the butyl acetate unit is hydrolyzed to form a butyl alcohol unit.

 [0035] Since the acrylate unit having a perfluoroalkyl group is hydrophobic by containing the copolymer resin as the synthetic resin and binding to the fiber material, the synthetic resin is The water repellency and oil repellency of the bonded fiber material can be improved. At the same time, the presence of hydrophilic bull monomer units improves water-repellency, but improves affinity for dyes to improve dyeability and absorb detergents. The effect of making it easier to remove dirt in water and improving hygroscopic water absorption is obtained. The force depending on the ratio of each structural unit of this copolymer resin The water repellency obtained by this copolymer resin is not high. This copolymer resin alone is about the first grade in the water repellency test described in JIS L 1092. It becomes. In order to obtain other effects such as the effect of improving water repellency and repelling dirt, it is necessary to use another synthetic resin in combination.

 [0036] Examples of the resin that can be used in combination with the copolymer resin as the synthetic resin include, for example, a silicone resin, a urethane resin, a polyester resin, and a perfluoroalkyl acrylate resin, which are used alone. Alternatively, a plurality of resins may be used in combination.

[0037] Among these, it is particularly preferable to include a silicone resin as the synthetic resin, because the silicone resin is molecularly bonded to the fiber material by a crosslinking agent, thereby exhibiting a durable softening effect. In particular, cotton, cellulose fibers obtained by organic solvent spinning, and the like become very stiff when wet, but the softness of silicon makes the fibers very soft even when wet. This effect makes the cotton material that is originally hard during dyeing and washing more flexible, resulting in a decrease in the strength of the fiber material and the occurrence of a slack. Examples of such silicon resins include amino silicon, epoxy silicon, and dimethyl silicon. [0038] When the synthetic resin contains an acrylate resin having a perfluoroalkyl group, the effect of improving the water repellency of the post-dyed fiber material obtained by bonding to the fiber material is high. If the acrylate resin also has a polyalkylene ether chain between the perfluoroalkyl group and the acryl group, the resulting water repellency is more excellent. However, even if it has the above acrylate resin and exhibits water repellency, it can maintain the hygroscopicity and water absorption of the resulting post-dyed fiber material by using it together with the copolymer resin.

[0039] Further, when the synthetic resin contains a urethane resin or a polyester resin, it is possible to adjust the texture and feel of the post-dyeing fiber material obtained by bonding to the fiber material. In addition, if the synthetic resin contains a water-absorbing polyester resin and the content of the resin having an effect of improving water repellency is negligible, it is possible to improve the water absorbability of the obtained fiber material for post-dyeing. . At that time, when used in combination with the copolymer resin, a fiber material for post-dyeing having water absorption and oil repellency can be obtained.

 [0040] By adding these synthetic resins, it is possible to solve various problems such as pilling, fibrils and weakness against tearing of the fiber material. For example, in order to suppress pilling, which occurs when a synthetic fiber short fiber sheet is rubbed in a dry state, it becomes a table ball due to static electricity or physical force, the copolymer resin, the silicon resin, or the polyester resin is used. It is good to add. The silicone resin softens the material and relaxes the physical force, the copolymer resin increases the official moisture content of the material to reduce static electricity generation, and the polyester resin suppresses static electricity generation, thereby preventing pilling. Demonstrate the effect.

 [0041] In addition, for the fibrils in which the cellulose fibers are squeezed in water or are generated by physical force even in a dry state, and the non-crystalline portion is destroyed and becomes fine hair, The fiber material can be softened and the destruction of the non-crystalline portion can be suppressed.

 [0042] Furthermore, compared with synthetic fibers, cellulose-based fibers such as cotton counts, rayon, and hemp are weak. For anti-tear tests, the above-mentioned silicone resin is added in the same way as above to make it stronger. That's the power S.

[0043] When these synthetic resins are used in a mixture with the resin solution, preferred concentrations thereof are as follows. When the copolymer resin is included, the resin solution in the resin solution The active ingredient is preferably 1% by weight or more, more preferably 2% by weight or more, although it depends on the material. If it is less than 1% by weight, the effect of adding this copolymerized resin is hardly expected. The higher the content, the higher the oil repellency of the resulting post-dyed fiber material. In order to make the oil repellency, which will be described later, about 3rd grade, about 2% by weight of the above copolymerized resin is included. It is good to include. On the other hand, it is preferably 6% by weight or less. Although it may exceed 6% by weight, since the production cost is high, the amount used is preferably small. However, when the synthetic resin contains a silicone resin, the silicone resin inhibits the effect of the copolymer resin, and therefore it is preferable that the copolymer resin is contained in an amount of about 6% by weight. When the synthetic resin is only the copolymer resin and the water-absorbing polyester resin, the water absorption can be improved while improving the oil repellency without improving the water repellency.

 [0044] When the synthetic resin includes an acrylate resin having a perfluoroalkyl group, the active ingredient in the resin solution is preferably 0.2% by weight or more, and 0.8% by weight. The above is more preferable. If it is less than 0.2% by weight, the effect of adding a perfluoroalkyl acrylate resin can hardly be expected. On the other hand, it is preferably 4% by weight or less. If it exceeds 4% by weight, the texture becomes slightly hard. However, when the amount of the copolymer resin or silicon resin is large, the amount necessary for exhibiting a sufficient effect increases. In this case, in order to make the water repellency described later 4th to 5th grade, if the water repellency of about 12% is sufficient if it contains about 12% of the above acrylate resin, the acrylate resin is 6% by weight. It is good to include a degree. In addition, as long as the water repellency is about grade 1, it can be realized only by the copolymer resin, even if the acrylate resin is not included.

[0045] When the synthetic resin contains a silicon resin, the active ingredient is preferably 0.026 wt% or more, more preferably 0.26 wt% or more. If it is less than 0.026% by weight, the effect of adding silicone resin is hardly expected. On the other hand, it is preferably 4% by weight or less, more preferably 2% by weight or less. Silicone resin lowers water repellency and oil repellency, so if it exceeds 4% by weight, the water repellency and oil repellency decline exhibited by the above-mentioned copolymer resin cannot be compensated. [0046] When these synthetic resins are used in combination, the total amount of the active ingredients of the synthetic resin contained in the resin solution is preferably 15% by weight or less, more preferably 10% by weight or less. Good. If it exceeds 15% by weight, the stability of the preparation may be impaired.

[0047] When the resin solution is applied to the fiber material, the pickup rate is preferably 10% or more, more preferably 40% or more. The pick-up rate is the ratio of the weight difference between the dried raw dough and the dough after being immersed in the solution, and is a value represented by the following formula (1).

 Pickup rate (%) = (Dough weight after soaking, Dry dough weight) / Dry dough weight X 10 0 …… (1)

 [0048] If this value is less than 10%, the synthetic resin in the resin solution will permeate into the fiber material using water as a medium, which requires a longer permeation time. It is because it ends up.

 [0049] When the resin solution is applied to the fiber material, the amount of the synthetic resin applied to the fiber material is 0.6% by weight or more for the copolymer resin. In the case of an acrylate resin having a monofluoroalkyl group, it should be 1.5% by weight or more, and in the case of a silicone resin, it should be 0.4% by weight or more. If it is more than these values, the effect by fully bonding a synthetic resin can be exhibited. In addition, when an isocyanate is included as a crosslinking agent when the crosslinking agent described later is included, if 0.3% by weight or more is applied to the fiber material, the reaction can be sufficiently performed. it can.

[0050] Examples of a method of bonding these synthetic resins to the functional group of the fiber material include a method of bonding the functional group of the synthetic resin and the functional group of the fiber material with a crosslinking agent. It is done. This cross-linking agent must be a compound having a plurality of reactive groups capable of binding to each functional group. For example, an aromatic block isocyanate or an aliphatic block isocyanate having an isocyanate group or a urethane group. Isocyanate compounds such as cyanate. The use of aromatic block isocyanate is preferable because the crosslinking temperature is low and the reactivity is high, but the whiteness may change slightly, and for products that require whiteness V, the reactivity is slightly higher. Although it is inferior, it is preferable to use an aliphatic block isocyanate. . When an isocyanate compound having a urethane group instead of an isocyanate group is used as a crosslinking agent, the urethane group portion needs to be converted into an isocyanate group by thermal dissociation or the like and then a crosslinking reaction must be caused.

[0051] When such a crosslinking agent is used, it is preferable to perform a heat treatment for causing a bridge reaction after the resin solution is applied to the fiber material. For this heat treatment, the minimum required temperature varies depending on the type of cross-linking agent. It is generally preferred that the cross-linking agent reacts with a force of 140 ° C or higher. On the other hand, if the temperature exceeds 200 ° C, the above fiber material may be damaged, and it is preferable that the temperature is 200 ° C or less, more preferably 180 ° C or less. In addition, if carpositimide or a silane coupling agent is used as a crosslinking agent, the durability will be insufficient.

 [0052] When such a cross-linking agent is included, the concentration of the cross-linking agent in the resin solution is preferably such that the effective component is 0.04% by weight or more. If the amount is less than 0.04% by weight, the fiber material and the synthetic resin cannot be sufficiently bonded, and the effect of improving the dyeability and the like becomes insufficient. On the other hand, it is preferably 4% by weight or less, more preferably 0.5% by weight or less. If it exceeds 4% by weight, the dyeability may be deteriorated and the texture may be deteriorated. In particular, when the above isocyanate compound is used, it is preferably 1% by weight or less.

 [0053] By incorporating into the fiber material a resin solution containing the synthetic resin as a main component and optionally containing the crosslinking agent or the like, the molecules of the fiber material and the molecules of the synthetic resin are combined. , Improve the dyeability of the fiber material. The main component means that the solid content in the solution is 50% by weight or more. Further, the solvent of the solution is not particularly limited, and water can be used.

 [0054] As a method of incorporating the resin solution into the fiber material, using a method in which the resin solution can be impregnated into the interior of the fiber material only, the effect of improving dyeability is uneven. Is preferable because it becomes <<.

[0055] The apparatus and method used when the resin solution is specifically applied to the fiber material is selected appropriately depending on the shape of the fiber material. For example, in the case of spun yarn and filament yarn, sizing machine, cheese processing machine, Hank dyeing machine, cassette processing machine, rope processing machine, A shearing machine or the like can be used. For woven fabrics, knitted fabrics and non-woven fabrics, a method of applying the resin solution by a dipping method or a coating method using a spreading machine (tentering machine) or the like while the cloth is spread can be used. In the case of a rope shape, the resin solution can be applied with a wins machine, a liquid dyeing machine, a drum dyeing machine or the like. In the case of a sewn product, a drum dyeing machine or a washer type processing machine can be used. Such provision may be performed once, or may be performed continuously twice or more. Depending on the fiber material, various fabric materials are used as secondary materials, so it takes time for the chemicals to penetrate evenly. It is possible to sufficiently permeate the above fiber material. When performing two or more times, the above-mentioned application may be performed continuously, or it may be dried and heat-treated once, and then applied again! /.

 [0056] After the resin solution is applied by these apparatuses, the fiber material is dried to remove water and react with the crosslinking agent, and heat treatment is performed to strengthen the reaction of the crosslinking agent. Such a fiber material for post dyeing can be obtained.

 [0057] The temperature of the drying treatment performed after the application of the resin solution is preferably 50 ° C or higher, and more preferably 130 ° C or higher. This is because if the temperature is lower than 50 ° C, it takes too much time S to dry because the evaporation of water is too slow, and the higher the temperature, the easier it is to dry. On the other hand, it is preferable that it is 200 degrees C or less. This is because if the temperature exceeds 200 ° C, the fiber material may be damaged by heat during drying. However, these optimum temperatures and the time required for the drying process vary depending on the heat source of the dryer and the heat treatment method. Also, it varies depending on the shape of the fiber material. For example, in the case of corn-like yarn, cheese-like yarn, and skein-like yarn, the drying heat treatment time is longer than that of the other yarn. Specifically, in the case of woven fabrics and knitted fabrics, it is better to use a spreading processing machine at around 160 ° C with a drying time of about 1 minute. In the case of cheese-like and corn-like yarns, 140 ° C It is recommended that the drying time be around 10 to 30 minutes.

[0058] Further, the temperature at which the heat treatment is performed after the drying treatment is preferably 130 ° C or higher, while it is preferably 200 ° C or lower, more preferably 180 ° C or lower. preferable. The heat treatment time is at least 10 minutes for fiber materials that are cheese-like or corn-like yarns, but at least 20 seconds for fabric materials such as woven fabrics and knitted fabrics that are preferred. Min Is preferable.

 [0059] The fiber material for post-dyeing according to the present invention, which can be post-dyed in this manner, enables uniform dyeing without hindering dyeability by the molecules of the synthetic resin bonded, and has a sufficient dyeing density. Can keep. In addition, since the synthetic resin is integrated with the fiber material, the physical strength of the fiber material is prevented from being lowered, and water repellency and oil repellency are exhibited.

 [0060] If the synthetic resin is simply impregnated, it will fall off from the fiber material during washing and dyeing, and the effect exhibited by the respective synthetic resin will not be exhibited after washing or decoloring, or Although there is a problem that it is significantly reduced, when the synthetic resin is combined with the fiber material, the synthetic resin does not fall off even during washing and dyeing, and after that, it continues to exhibit the results. I can do it.

 [0061] When the copolymer resin contained in the synthetic resin is combined with the fiber material, sufficient oil repellency is exhibited even after washing and dyeing. In addition, the acrylate resin having the perfluoroalkyl group as the synthetic resin combines with the fiber material, thereby exhibiting sufficient oil repellency even after washing and dyeing.

[0062] Furthermore, when a silicone resin is used as the synthetic resin, the effect of softening the texture of the fiber material obtained by the silicone resin is not lost even during washing and dyeing, but in a bath immersed in water. Then, the fiber material can be softened more than the dry state. As a result, a decrease in strength of the fiber material can be prevented. This effect is particularly suitable when the fiber material is a cellulose material that becomes very hard when wet.

[0063] The fiber material for post-dyeing according to the present invention has high water repellency and oil repellency, and since the surface tension can be made smaller than that of polyester, it is not only excellent in dyeability but also has high moisture permeability. It can be used as a fiber material that is resistant to oil stains.

[0064] Specifically, the fiber material for post-dyeing that is strong in the present invention has a water repellency test result of JIS L 1092 that can achieve a water repellent grade of 2 or higher, and achieve this value. It is preferable that it is a thing. If it is grade 1, the water repellency is insufficient, and in order to ensure sufficient water repellency, as is conventionally done, the product is dyed and dried and then water-repellent by a water-repellent spray etc. It is necessary to do. In this case, the texture of the water-repellent durability becomes harder, and when the fiber material is a synthetic fiber such as polyester, the problem is that the friction fastness is lowered. The maximum grade is Grade 5, and it may be Grade 5 that is rarely required to be Grade 4 or higher except when the fiber material is a coat. Products with water repellency or grade 5 can be achieved by adjusting the concentration ratio of the chemicals used. The post-dyed fiber material according to the present invention does not cause a problem in dyeability even if the above water repellency is achieved.

 [0065] Further, the post-dyed fiber material according to the present invention is an oil repellency test described in AATCC (American Association of Textile Chemists and Colorists). The result is oil repellency of 1st grade (corresponding to surface tension of 32 dyne / cm or less) or higher, and it is preferable to achieve this value. Grade 2 or higher is more preferable. Grade 3 or higher Is more preferable. If it is not grade 1, the oil repellency will be insufficient, and oleic acid contained in human sweat oil equivalent to grade 1 will adhere. It is more preferable to satisfy the third grade (corresponding to 27.3 dyne / cm or less) because oil contamination of n-hexadecane can be prevented. It should be noted that the post-dye fiber material, which has the power of the present invention, does not cause a problem in dyeability even if the above oil repellency is achieved. The maximum grade is grade 8, but the surface tension of silicon resin is 24 dyne / cm and the surface tension of fluororesin is lOdyne / cm. Since it is practically difficult to achieve the class (19.8 dyne / cm), it is realistic that it is actually 7th class or lower.

 [0066] Furthermore, the post-dyed fiber material according to the present invention can have a surface tension of 32 dyne / cm or less according to a general preparation procedure. Since this value is smaller than ordinary polyester fiber and smaller than most oils, most oil stains are strong in this invention, and can be easily wiped off without penetrating into the fiber material for post-dyeing. Power S can be. Also, the smaller the surface tension, the better. In the present invention, the surface tension of ordinary polyester not bonded is 45 dyne / cm and nylon is 60 dyne / cm, whereas the surface tension of water is 70 dyne / cm.

[0067] Furthermore, the fiber material for post-dyeing, which is suitable for the present invention, is described in JIS L 1099A-1. The result in the moisture permeability test can be improved from a fiber material that is not processed. Moisture permeability is not directly related to dyeability! /, But exhibits the beneficial effect of absorbing sweat, etc. when using fiber materials for post-dyeing that are good for moisture permeability in clothes, etc. To do. Such good moisture permeability is established even if the water repellency is high. This is because the water vapor that is the target of hygroscopicity is smaller than the liquid water that is the target of water repellency, and they exhibit different behavior. When the conventional water-repellent finish is performed after dyeing, the moisture permeability is lower than that of the fabric not subjected to the water-repellent finish. In the present invention, the moisture permeability can be improved.

 [0068] On the other hand, the fiber material for post-dyeing according to the present invention improves the water absorbability of the fiber material for post-dyeing by selecting only the above-mentioned copolymer resin or water-absorbing polyester resin as the synthetic resin to be applied. You can also.

 [0069] When the acrylate resin having a perfluoroalkyl group or the copolymer resin is present as the synthetic resin, the effect of improving the oil repellency as described above is particularly high. In addition, the copolymer resin is inferior to the acrylate resin in terms of surface tension, but has a high effect of repelling oil because it is hydrophilic in the dry state. Furthermore, the copolymer resin is hydrophilic in water such as during dyeing and washing, so it improves the washing effect and easily removes dirt, and also has the effect of improving the adsorptivity of the dye during dyeing. It also has the effect of increasing hygroscopicity. On the other hand, since the acrylate resin does not have a hydrophilic group, the effect of improving water repellency is high.

 [0070] In the fiber material for post-dyeing, which is strong in the present invention, at least one of the above water repellency and oil repellency values can be easily achieved, and in particular, the above acrylate resin or the above copolymer. By adjusting the resin content, both values can be easily met. In other words, the water repellent property can be improved by the acrylate resin, and the moisture permeability can be improved by the copolymer resin. By combining these synthetic resins with the fiber material, for example, it is possible to realize clothes that can play rainwater and the like, while being able to remove moisture from internal sweat.

[0071] When dyeing the fiber material for post-dyeing according to the present invention, depending on the shape of the fiber material, treatment can be performed under any conditions suitable for them, and the dyeing means is particularly limited. It is not something. Specifically, disperse dyes, acid dyes, reactive dyes as dyes Any dyes such as direct dyes, vat dyes and basic dyes can be used.

 [0072] Further, as a dyeing method, any method such as dip dyeing or cold patch dyeing can be used. If the fiber material is spun yarn or filament yarn, cloth-like materials such as woven fabrics, knitted fabrics, and nonwoven fabrics that can be used with casserole processing machines, cheese calorie machines, rope processing machines, slasher processing machines, etc. are liquid dyeing. Or a cold patch dyeing machine may be used. In addition, when the fiber material is a knitted fabric other than polyester, it is preferable to use wins, and for dyeing woven fabrics and nonwoven fabrics, it is preferable to use a zicker dyeing machine or a batch dyeing machine. In addition, when dyeing fiber materials after sewing, the shape of the sewn product can be changed by using a drum dyeing machine, or by using a dyeing machine for dip dyeing that is difficult to apply tension, such as a normal pressure washer and high pressure washer. It is preferable because it is difficult to damage.

 [0073] The post-dyeing fiber material obtained by post-dying the post-dyeing fiber material according to the present invention was subjected to a water repellency test according to JIS L 1092, which was sufficiently dried after the post-dyeing. It is preferable that the above-mentioned and grade 5 or less can be maintained even after dyeing. The high water repellency after dyeing means that the synthetic resin is not dropped during the dyeing process, and is firmly integrated with the fiber material by intermolecular bonding. It is. If these values can be achieved, it is no longer necessary to apply a water repellent by spraying, which has been practiced after dyeing, and the product has high quality notes, jackets, coats, coats, interiors. It will be suitable for the material.

 [0074] Further, the dyed fiber material is the result of the oil repellency test described in AATCC118-2002.

 1S Grade 2 or higher is preferred Level 3 or higher is more preferred. If it is lower than grade 1, the oil repellency will be insufficient and it will be extremely weak against oil stains. The standard is that oil repellency grade 2 has a surface tension of 29 · 6 dyne / cm and less than 32 dyne / cm of sweat oil (oleic acid), so oil repellency of grade 2 or higher is the minimum requirement. This is because if it is 3rd grade or higher (27.3 dyne / cm), it will be effective against most oily soils. On the other hand, it is preferable that it is 7th grade or less. As above, Grade 8 is difficult due to the limited oil repellency.

[0075] Further, when the dyed fiber material is a cloth-like material composed of a woven fabric, a knitted fabric, a non-woven fabric or a composite material thereof, the surface tension is preferably 31.5 dyne / cm or less 29. More preferably, it is 6 dyne / cm or less. 31. If it exceeds 5 dyne / cm, the component of sweat oil This is because the oleic acid is easily attached. This value is smaller than the surface tension of conventional cotton, polyester, nylon, and other fibers that are dyed as they are without being processed. However, even if the amount of chemicals used is reduced, the same processing effect can be obtained. On the other hand, since the surface tension is not more than oil repellency, it is preferably 21.4 dyne / cm or more.

 [0076] These water repellency, oil repellency, and surface tension values are values that can be easily achieved by performing normal dyeing using the fiber material for post-dyeing. It is more preferable that the value of is also satisfied. In particular, when the synthetic resin is a phthalate resin having a perfluoroalkyl group or a copolymer resin having an acrylate unit having a perfluoroalkyl group and a hydrophilic butyl monomer unit, The tension can be easily reduced to 29.6 dyne / cm or less. Fluorine-containing resins such as these have a surface tension of about lOdyne / cm in the form of a film, and a very high oil repellency. When intermolecularly bonded to the above fiber material, what is the value up to that point? Don't be. Therefore, it is better to copolymerize with the hydrophilic butyl monomer to exert the effect of improving oil repellency by repelling the oil component due to its water-soluble property. In addition, since the water repellency of the resin obtained by homopolymerizing the hydrophilic butyl monomer is only about the first grade, these effects can be obtained by using a copolymer resin with an acrylate having a perfluoroalkyl group. It can complement each other and is a preferable resin.

 [0077] Regarding the post-dyed fiber material, the water repellency after washing 30 times by the method described in JIS L 0217 103 is preferably 1st grade or more and 5th grade or less. That is, it is preferable that the decrease in water repellency can be suppressed even after washing. For the same reason, the oil repellency after washing 30 times is preferably 2nd grade or more and 7th grade or less.

 [0078] The post-dye fiber material according to the present invention is excellent in water repellency and oil repellency as it is, but after the post-dyeing, water repellency, oil repellency, improved fastness, antibacterial, Processing such as electricity control and deodorization may be performed. Even during these processes, since the fibers are integrated with the synthetic resin, the fibers are easily damaged and the properties such as the water repellency, oil repellency and surface tension are easily maintained. That is, it is preferable to satisfy the water repellency, oil repellency, and surface tension values of the dyed fiber material before washing.

[0079] As described above, at least hydroxyl group, amino group, amide group, carboxyl group, or urethane group is present. /! Treatment for including a resin solution mainly composed of a synthetic resin that reacts with the functional group of the fiber material to improve the dyeability of the fiber material. By processing, it is possible to produce a fiber material for post-dyeing after washing, which satisfies the above conditions for water repellency, oil repellency and surface tension of the fiber material, and has high dyeability and high washing durability. .

The polyester fabric, which is a fiber material for post-dying obtained in this way, was dyed and reduced and washed under the same dyeing conditions as in Example 8. As the dye, Nippon Kayaku Co., Ltd .: KP Black BRN-SF 200 was used at a concentration of 5% owf. After dyeing, K / S value, water repellency and moisture permeability were measured. The results are shown in Table 17. In addition, when the K / S value is expressed in relative values, if Comparative Example 11 is 100, Implementation 14 is 104.9.

[0168] [Table 17]

[0169] (Comparative Example 11)

 In Example 14, a dyed fiber material was obtained by the same procedure as in Example 14 except that the resin solution was not applied and drying and baking were not performed. Table 17 shows the results of similar measurements.

 In Example 15, a dyed fiber material was obtained by the same procedure as in Example 15 except that the resin solution was not applied and drying and baking were not performed. Table 18 shows the results of similar measurements.

[0174] (Result)

 Similar to Example 14, Example 15 also exhibited higher water repellency and higher moisture permeability than those not provided with the resin solution.

 [0175] (Examples 16 to 18)

 The same polyester fabric as in Example 14 was used as the fiber material, and scouring and drying were performed in the same procedure, and each resin solution having a mixing ratio shown in Table 19 below was applied to the fiber material. In the table, “SS” iiSM-Cube SS, “: L” ί SM-Cube KL, “SRM-65J” indicates the Mei force finish SRM-65, which is a polyester resin solution. The resin solution was applied to a fiber material at a pick-up rate of 60% using a Pad-Drier tester manufactured by Sakurai Mfg. Co., Ltd.

 [0176] [Table 19]

[0177] After drying in an environment of 120 ° C, heat treatment was performed at 160 ° C for 2 minutes using a Shimadzu Corporation baking test machine.

Therefore, it was found that oil repellency and water absorption can be adjusted by adjusting the content of SRM-65, which is a polyester resin solution. In addition, with polyester fibers, even if conventional oil repellency and water absorbency are imparted, they will be reduced by subsequent post-dying.

The power of unsuccessful post-dyeing The power of the present invention does not reduce the dyeing density in post-dyeing, and it does not reduce oil repellency or water absorption by post-dyeing. That's it.

The dyeing temperature was 120 ° C for 60 minutes, and the bath ratio was 1:20.

 [0183] After dyeing, soaking was carried out with water at 80 ° C for 20 minutes, and then reduction washing was performed.

 The reducing cleaning solution contains 7g / L of reducing agent (Mensei Chemical Co., Ltd .: MRC powder), 5g / L of detergent (Makisei Chemical Co., Ltd .: Lakkor ST-700), and 5cc / L of acetic acid. This was used and washed at 80 ° C for 20 minutes.

 [0184] After that, neutralize with 60 ° C solution containing 2g / L of soda ash for 10 minutes, rinse with hot water for 10 minutes at 60 ° C water, and finally at 120 ° C environment. And dried for 2 minutes. The dyed fiber material thus obtained was measured for water repellency and oil repellency. The results are shown in Table 20 (shown as “L-0” in the table). Further, the dyed fiber material was subjected to a washing durability test 20 times under the washing conditions of JIS L-0217103 method, and then the water repellency and oil repellency were evaluated.

Thereafter, under the same conditions as in Example 19, water repellency and oil repellency values before and after the washing durability test were measured. The results are shown in Table 20.

[0187] (Result)

In Comparative Example 14 using the conventional water-repellent processing method after dyeing, washing durability was hardly exhibited, and water repellency and oil repellency after washing were almost lost. However, in Example 19, which is a fiber material for post-dyeing processed with the resin solution according to the present invention, the washing durability test is performed. Even after the test, the oiliness and water repellency were hardly lowered.
