Description

The present invention relates to a processing method for improving post-dyeing dyeability while imparting water repellency to a fiber material .

  Highly durable processing such as water-repellent functional processing, oil-repellent functional processing, flexible processing, anti-stain processing, and anti-pilling processing used in conventional textile products dyes yarn, knitted fabric, woven fabric, nonwoven fabric, etc. Later, after being processed with resin, it is then commercialized as clothes, bags, hats, and sports clothing by sewing. Also, yarns are processed into resin after being dyed, processed into knitted fabrics and woven fabrics.

  The 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. However, in today's fast-changing consumer preferences, it is most important to shorten product delivery times. After the manufacturer has grasped consumer needs such as color, size, material, and pattern, Manufacturing, fabric manufacturing, dyeing processing, resin processing, and sewing, it takes too much time and supplies consumers the products they want in a timely manner. Is impossible.

  Especially for fashionable products, the sales period that can be placed at the store is short, and even if consumer orientation is obtained as information at the store, items that do not fit the consumer's preference when sewing products that have already been determined in color, size, and pattern are in stock. Will become 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 not be in time and you will miss a business opportunity.

  For this reason, the product is dyed after the product is completed, so that it is possible to meet the short delivery time. However, the color management is stable especially for plant fibers such as cotton and hemp and regenerated fibers such as rayon. Swelling and wrinkles are likely to occur, dyeing unevenness is likely to occur, and it is almost impossible to perform durable water-repellent or oil-repellent processing after dyeing. It was limited to the application level of water repellent spray, and could not be a high-class product. In addition, with synthetic fibers and semi-synthetic fibers, when water-repellent processing and oil-repellent processing were performed after normal dyeing or product dyeing, the fastness to friction decreased, and this tendency was particularly pronounced with polyester microfiber materials.

  On the other hand, Patent Document 1 discloses 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. This is because fiber products made of synthetic fiber, semi-synthetic fiber, regenerated fiber, natural fiber, etc. are pre-shaped into a woven fabric, knitted fabric, non-woven fabric, etc., and a synthetic resin film is formed on the surface by a laminating method. The dyeing property of the dye is improved.

JP 2002-105865 A

  However, in the method of Patent Document 1, the object to be processed is limited to the fabric in order to form the synthetic resin film. In addition, it is necessary to use an adhesive in order to bond the synthetic resin film, and there is a problem that water repellency, washing resistance and the like of the obtained fiber product are insufficient.

  In addition, even if the water repellent is used in advance before dyeing, not only the dyeability is deteriorated, but also the water repellent falls off during the dyeing process, and the dyed fiber The material has almost no water repellency. For this reason, it has been conventionally considered that post-dyeing after water-repellent processing is virtually impossible. On the contrary, when water repellent processing is performed after dyeing, it is necessary to perform baking in order to obtain durability, but there is a problem that fastness is reduced by this heat.

  Furthermore, even when normal dyeing is performed instead of post-dyeing, fibers are often damaged during dyeing. 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 vegetable fiber and animal fiber, alkali is used in the preparatory processing required before dyeing, but there is a problem that sufficient pretreatment cannot be performed due to severe damage to animal fiber. Even in the dyeing process itself, it was difficult to dye in a dark color without damaging animal fibers. Moreover, since it is a composite fiber, the dye used must be effective for both materials, resulting in a longer dyeing time and further damage to the fiber material. Recycled fibers such as rayon cannot be a durable product due to severe damage and reduced strength during dyeing and severe damage in washing tests after dyeing.

  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. A large amount of glue is applied to the fabric woven using the spun yarn. Since the agent is adhered, it is necessary to remove it using a large scouring desizing machine at the dyeing processing plant, and the burden of large capital investment, energy use, wastewater treatment, etc. has become large.

  Also, it has been known that, even in a product obtained by a conventional method in which resin processing is performed after dyeing, texture deterioration, surface whitening, pilling, strength reduction, and the like occur in the washing process. For this reason, it is difficult to maintain these functions when the dyeing process, which is more severe than the washing conditions, is performed after resin processing that improves water repellency, oil repellency, and flexibility. It was thought.

  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 hardly damaged and have high dyeability after dyeing. An object of the present invention is to provide a fiber material for post-dyeing that is highly water-based, oil-repellent, and wash-resistant.

  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, having a functional group that binds to the functional group of the fiber material, and the fiber The above-mentioned problem has been solved by including a resin solution mainly composed of a synthetic resin that improves the dyeability of the material, and combining the molecules of the synthetic resin with the molecules of the fiber material. That is, by combining a synthetic resin as a molecule with the functional group of the fiber material, the synthetic resin not only improves the dyeability but also exhibits water repellency and oil repellency. It was made difficult to peel off from the fiber material during processing.

  The shape of the fiber material to be combined with the synthetic resin according to the present invention is not particularly limited. Specifically, cotton, sliver, filament yarn, spun yarn, sewing yarn, or a woven fabric, a knitted fabric, or a nonwoven fabric made of these, Or it can use for the sewing product which consists 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 polyamide. Aromatic polyamide fibers such as fiber, aramid fiber, polyurethane, diacetate, triacetate, or composite fiber using a plurality of these.

  Examples of the method of bonding the molecule of the synthetic resin and the molecule of the fiber material include a method in which a crosslinking agent that bonds a functional group of each molecule is included in the resin solution, and the molecules are bonded by the crosslinking agent. It is done. As such a crosslinking agent, an isocyanate compound having a plurality of isocyanate groups can be used.

  In particular, since the synthetic resin includes a copolymer resin composed of an acrylate unit having a perfluoroalkyl group and a hydrophilic vinyl monomer unit, it has both a hydrophilic part and a hydrophobic part. In addition, in the air, the perfluoroalkyl group exerts water and oil repellency to repel dirt, and in water, the hydrophilic end of the vinyl group appears on the surface to exert hydrophilicity and remove dirt. . In addition, since there is a hydrophilic group, dyeability and hygroscopicity can be improved.

  Furthermore, when the above synthetic resin is added to the above copolymer resin, perfluoroalkyl acrylate resin, polyester resin, silicon resin, urethane resin, etc. that do not have a hydrophilic group, the effects that are tailored to the added resin are given. can do. Perfluoroalkyl acrylate resins improve water repellency, and silicon resins improve strength and flexibility in the bath. When a polyester resin or a urethane resin is included, a fiber material having a texture characteristic of each resin can be obtained.

  The fiber material for post-dyeing combined with the above synthetic resin can have an oil repellency result according to the oil repellency test described in AATCC 118-2002 of at least second grade, and can be improved up to seventh grade. . Moreover, 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 post-dyeing fiber material according to the present invention enables post-dying not only for fabrics but also for all textile products. In addition, any fiber with a functional group that reacts can be used, so that many fiber materials can be post-dyed, and the occurrence of damage, wrinkles, and material damage that easily occurred during or after post-dyeing. 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, so that products can be shipped in a short period of time according to market trends. Thus, loss of sales opportunities can be reduced and unsold products can be prevented from being generated.

  The fiber material that can be post-dyed is a fiber material that has high washing resistance, water repellency and oil repellency, and a low surface tension, because the synthetic resin having improved dyeability is bonded to the fiber material by molecules. For this reason, since the spray application of the water repellent etc. which were conventionally performed after product dyeing becomes unnecessary, dyeing | staining can be performed easily. 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 a synthetic resin, the durability of the fiber material itself is increased, and the fiber material is less likely to be damaged during dyeing as compared with a conventional fiber material. As a result, in the case of spun yarn, it is not necessary to protect the yarn by carrying out a sizing process that has a large burden of desizing after weaving.

  The present invention will be described in detail below. 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, and combines the functional group of the fiber material with the dyeability of the fiber material. It is a fiber material for post-dyeing in which a resin solution containing a synthetic resin to be improved as a main component is included and molecules of the synthetic resin are combined with molecules of the fiber material. Here, to improve the dyeability means to obtain a product having a higher dye density under the same conditions, and the dye density is, for example, the ratio between the light absorption coefficient K and the scattering coefficient S. It is represented by the K / S value.

  The fiber material that can be post-dyed in the present invention is not particularly limited in shape, and raw materials and yarns such as cotton, sliver, filament yarn, spun yarn, sewing yarn, woven fabric, knitted fabric, or nonwoven fabric made of these In addition, it is possible to enable post-dyeing on any state of the fabric and the sewing product made of these fabrics and yarns.

  Examples of the fiber material include plant 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, and animals such as silk and wool. Fiber, polyester, polyurethane, aliphatic polyamide fiber (including 6-nylon and 6,6-nylon), synthetic fiber such as aromatic polyamide fiber, and semi-synthetic fiber such as diacetate and triacetate. Specific examples of cellulose fibers obtained by the organic solvent spinning method include tencel and lyocell (both registered trademarks), and examples of copper ammonia rayon include Bemberg and cupra (both registered trademarks). It is done.

  Among these fiber materials, vegetable fiber, regenerated fiber, and diacetate have a hydroxyl group, and polyester also has a hydroxyl group at the terminal. Polyamide fibers and animal fibers have amino groups, carboxyl groups, and amide groups. Moreover, the terminal of polyester has a carboxyl group, and nylon has an amide group. Furthermore, the polyurethane fiber has a urethane group at the end. Triacetate theoretically has all hydroxyl groups changed to acetyl groups, but in practice, some hydroxyl groups remain and the hydroxyl groups react.

  Among these, polyester fibers, in particular, have been difficult to impart not only dyeability but also moisture permeability and water repellency by conventional methods, but synthetic resins that improve dyeability can be obtained by the method according to the present invention. Moisture permeability can be easily provided by bonding, and water repellency can be easily provided by bonding other synthetic resins.

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

  Specifically, in the scouring, impurities attached to the fiber material can be removed so that the synthetic resin can be easily bonded. Cotton contains natural contaminants such as natural wax and pectin, which can be removed by high-temperature treatment with high-concentration alkali or detergent. In the case of blending and union of cellulose and animal fibers such as cotton / wool, animal fibers are dissolved if alkali is used, so scouring with an acidic solution is performed. In addition, although there is no contaminant in synthetic fiber, since the oil agent used in a process has adhered, it removes using detergent at high temperature.

  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 an alkali are used in combination, but in the case of a fiber material containing animal fibers such as wool, the fiber is melted and bleaching is performed with the alkali used as low as possible.

  Desizing is a sizing that gives a glue to prevent warp from being damaged when making cotton fabric or cotton composite spun yarn (including rayon, cellulose fiber and hemp, obtained by organic solvent spinning) into a woven fabric. Processing is to remove the glue. In the case of 100% cotton, a high-concentration alkali and an oxidizing paste remover are used in combination, and the 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 with a high concentration of alkali for a long time, so the paste is removed using an enzyme rather than an oxidized desizing method that uses alkali together. To do. In the case of cotton / wool etc., the paste is removed by an enzymatic method without using an alkaline agent as in the case of rayon. In addition, since sizing is not performed with synthetic fibers such as polyester, desizing is unnecessary. In addition, the knitted fabric does not require sizing, so that desizing is not necessary.

  The synthetic resin to be bonded to the functional group of these fiber materials preferably includes a copolymer resin composed of an acrylate unit having a perfluoroalkyl group and a hydrophilic vinyl monomer unit. Among these, the presence of the hydrophilic vinyl monomer unit increases the affinity with the dye, thereby improving the dyeability. Such a copolymer resin may be a copolymer obtained by simply mixing the monomers as the units, or a block copolymer bonded after the respective monomers are polymerized. Good.

  The acrylate unit having a perfluoroalkyl group may be an ester unit having a structure in which a perfluoroalkyl group is bonded to an acrylic acid unit, and has a polyalkylene ether chain between the perfluoroalkyl group and the acrylic group, When the ester unit has a structure as in (1), the obtained effect such as water repellency is more excellent.

  Examples of the hydrophilic vinyl monomer unit include a vinyl alcohol unit and an acrylate ester unit having a hydrophilic group in the ester portion. In the case of using a vinyl alcohol unit, for example, after copolymerization using vinyl acetate, the vinyl acetate unit is hydrolyzed to obtain a vinyl alcohol unit.

  Since the acrylate unit having a perfluoroalkyl group is hydrophobic by including the copolymer resin as the synthetic resin and bonding with the fiber material, the water repellency of the fiber material combined with the synthetic resin, Oil repellency can be improved. At the same time, the presence of the hydrophilic vinyl monomer unit improves water-repellency, but improves the dyeability by improving the affinity with the dye and makes it easier to absorb the detergent. The effect of making it easy to remove dirt and improving hygroscopic water absorption is obtained. Although depending on the ratio of the respective structural units of this copolymer resin, the water repellency obtained by this copolymer resin is not high, and this copolymer resin alone is 1 in the water repellency test described in JIS L 1092. It becomes a grade. 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.

  Examples of the resin that can be used in combination with the copolymer resin as the synthetic resin include a silicon resin, a urethane resin, a polyester resin, and a perfluoroalkyl acrylate resin. These may be used alone, or a plurality of resins may be used. A resin may be used in combination.

  Among these, it is particularly preferable to include a silicone resin as the above 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 and cellulose fibers obtained by an organic solvent spinning method have a very stiff texture when wet, but the softening effect of silicon makes the fiber very soft even when wet. This effect makes the cotton material that would otherwise be hard during dyeing or washing more flexible, making it less likely to reduce the strength of the fiber material and cause it to flare. Examples of such a silicon resin include amino silicon, epoxy silicon, and dimethyl silicon.

  Moreover, 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 this acrylate resin also has a polyalkylene ether chain between the perfluoroalkyl group and the acrylic group, the resulting water-repellent effect will be more excellent. However, even if it has the acrylate resin and exhibits water repellency, the hygroscopicity and water absorption of the resulting post-dyed fiber material can be maintained by using it together with the copolymer resin.

  Furthermore, when the synthetic resin contains a urethane resin or a polyester resin, it is possible to adjust the texture and feel of the post-dyed fiber material obtained by bonding to the fiber material. Further, 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, the water-absorbing property of the resulting post-dyed fiber material can be improved. At that time, when used in combination with the copolymer resin, it is possible to obtain a fiber material for post-dying having water absorption and oil repellency.

  By adding these synthetic resins, various problems such as pilling, fibrill, and weakness against tearing of the fiber material can be solved. For example, the copolymer resin, the silicon resin, or the polyester resin may be added in order to suppress pilling that forms cotton balls due to static electricity or physical force when the synthetic short fiber cotton is rubbed in a dry state. The silicone resin softens the material to relieve physical force, the copolymer resin increases the official moisture content of the material to weaken static electricity generation, and the polyester resin suppresses pilling by suppressing static electricity generation. Demonstrate.

  In addition, for fibrils where cellulose fibers are squeezed in water or are generated by physical force even in a dry state, and the amorphous portion is destroyed and become fine hair, adding the silicone resin described above, the fiber material becomes It can be softened and the destruction of the amorphous portion can be suppressed.

  Furthermore, compared with synthetic fibers, cellulose fibers such as cotton counts, rayon and hemp are weak and can be strengthened by adding the silicone resin in the same manner as described above.

  In the case where these synthetic resins are mixed and used in the resin solution, preferred concentrations thereof are as follows. When the copolymer resin is included, the active ingredient in the resin solution is preferably 1% by weight or more, more preferably 2% by weight or more, although it depends on the raw material. If it is less than 1% by weight, the effect of adding the 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, it is preferable to contain about 2% by weight of the above-mentioned copolymer resin. It is good to include. On the other hand, the content 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 silicon resin, it is preferable that the copolymer resin is contained in an amount of about 6% by weight because the silicon resin inhibits the effect of the copolymer resin. Further, when the synthetic resin is only the copolymer resin and the water-absorbing polyester resin, it is possible to improve water absorption while improving oil repellency without improving water repellency.

  When the synthetic resin contains an acrylate resin having a perfluoroalkyl group, the active ingredient in the resin solution is preferably 0.2% by weight or more, and more preferably 0.8% by weight or more. If it is less than 0.2% by weight, the effect of adding the perfluoroalkyl acrylate resin is hardly expected. On the other hand, the content 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 the silicon resin is large, the amount necessary for exhibiting a sufficient effect is increased. In this case, in order to make the water repellency described later 4th to 5th, about 12% of the acrylate resin may be included. If the water repellency may be about 3rd, about 6% by weight of the acrylate resin is included. Good. In addition, if it is about water-repellent first grade, even if it does not contain the said acrylate resin, it can implement | achieve only with the said copolymer resin.

  When the synthetic resin contains a silicon resin, the active ingredient is preferably 0.026% by weight or more, and more preferably 0.26% by weight or more. If it is less than 0.026% by weight, the effect of adding the silicone resin is hardly expected. On the other hand, it is preferably 4% by weight or less, and preferably 2% by weight or less. Since the silicone resin decreases water repellency and oil repellency, when it exceeds 4% by weight, the decrease in water repellency and oil repellency exhibited by the copolymer resin and the like cannot be complemented.

  Moreover, when using these synthetic resins together, 15 weight% or less is preferable and the total amount of the active ingredient of the said synthetic resin contained in the said resin solution is more preferable in it being 10 weight% or less. This is because if it exceeds 15% by weight, the stability of the preparation liquid may be impaired.

When the resin solution is applied to the fiber material, the pickup rate is preferably 10% or more, and more preferably 40% or more. The pickup 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 immersion−Dry weight) / Dry weight × 100 (1)

  If this value is less than 10%, the synthetic resin in the resin solution will not easily penetrate into the fiber material using water as a medium, and a longer penetration time will be required. is there.

  In addition, when the resin solution is applied to the fiber material, the amount of the synthetic resin applied to the fiber material may be 0.6% by weight or more in the case of the copolymer resin. If it is an acrylate resin, it may be 1.5% by weight or more, and if it is a silicon resin, it may 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. Moreover, when it contains the crosslinking agent mentioned later and isocyanate is included as a crosslinking agent, when 0.3 weight% or more is provided with respect to the said fiber raw material, it can fully react.

  Examples of the 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. This cross-linking agent needs to be a compound having a plurality of reactive groups capable of binding to each functional group. For example, an isocyanate group such as an aromatic block isocyanate or an aliphatic block isocyanate having an isocyanate group or a urethane group. Compounds. Use of an aromatic block isocyanate is preferable because the crosslinking temperature is low and the reactivity is high, but the whiteness may change slightly. For products that require whiteness, the aliphatic block is slightly less reactive. It is preferable to use isocyanate. In addition, when using the isocyanate type compound which has a urethane group instead of an isocyanate group as a crosslinking agent, after making a urethane group part into an isocyanate group by thermal dissociation etc., it is necessary to raise | generate a crosslinking reaction.

  In the case of using such a crosslinking agent, it is preferable to perform a heat treatment for causing a crosslinking reaction after the resin solution is applied to the fiber material. As this heat treatment, the minimum necessary temperature varies depending on the type of the crosslinking agent, but it is preferably 140 ° C. or higher because the crosslinking agent generally reacts easily. On the other hand, when the temperature exceeds 200 ° C., the fiber material may be damaged, so that the temperature is preferably 200 ° C. or less, and more preferably 180 ° C. or less. In addition, when carbodiimide and a silane coupling agent are used as a crosslinking agent, durability will be insufficient.

  When such a crosslinking agent is contained, the concentration of the crosslinking agent in the resin solution is preferably 0.04% by weight or more of the active ingredient. This is because 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 dyeability and the like becomes insufficient. On the other hand, it is preferably 4% by weight or less, and 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.

  By combining the fiber material with a resin solution containing the synthetic resin as a main component and optionally containing the cross-linking agent or the like, the fiber material molecule and the synthetic resin molecule are combined to form the fiber material. Improves dyeability. The main component means that the solid content in the solution is 50% by weight or more. Moreover, the solvent of a solution is not specifically limited, Water can be used.

  As a method of including the resin solution in the fiber material, unevenness occurs in the effect of enhancing the dyeability by using a method capable of impregnating the resin solution not only on the surface of the fiber material but also inside. Since it becomes difficult, it is preferable.

  Specifically, the apparatus and method used when applying the resin solution to the fiber material is selected appropriately depending on the shape of the fiber material. For example, for spun yarn and filament yarn, a sizing machine, a cheese processing machine, a Hank dyeing machine, a casserole processing machine, a rope processing machine, a slasher processing machine, and 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 (tenter machine) or the like while the cloth is spread can be used. In the case of the 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 application may be performed once, or may be performed continuously twice or more. Depending on the fiber material, various fabric materials are used as auxiliary materials, so it may take time for the chemicals to penetrate evenly. Can also penetrate sufficiently. When performing twice or more, you may perform said provision continuously or may re-apply after drying once and heat-processing.

  After applying the resin solution with these devices, the fiber material is dried to remove moisture and react with the crosslinking agent, and heat treatment is performed to strengthen the reaction of the crosslinking agent. A fiber material can be obtained.

  Moreover, the temperature of the drying process performed after giving the said resin solution is preferable in it being 50 degreeC or more, and it is more preferable in it being 130 degreeC or more. This is because if the temperature is lower than 50 ° C., the temperature is too low and the water evaporates slowly, and it takes a long time to dry. The higher the temperature, the easier the drying. 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, the optimum temperature 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 a corn-like thread, a cheese-like thread, or a skein-shaped thread, the drying heat treatment time is longer than that of the other thread. Specifically, in the case of woven fabrics and knitted fabrics, it may be performed at a temperature of about 160 ° C. and a drying time of about 1 minute using an expansion processing machine. In the case of cheese-like and corn-like yarns, the temperature is about 140 ° C. The drying time is preferably about 10 to 30 minutes.

  Furthermore, the temperature at the time of performing the heat treatment after the drying treatment is preferably 130 ° C. or higher, on the other hand, preferably 200 ° C. or lower, and more preferably 180 ° C. or lower. The heat treatment time is preferably 10 minutes or more and 1 hour or less if the fiber material is cheese-like or corn-like yarn, and 20 seconds or more and 2 minutes or less if the fiber material is a woven fabric, knitted fabric, or the like. Is preferable.

  The fiber material for post-dyeing according to the present invention, which can be post-dyed in this way, enables uniform dyeing without hindering dyeability by the above-mentioned synthetic resin molecules, and maintains a sufficient dyeing concentration. Can do. 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 effects such as water repellency and oil repellency are exhibited.

  Simply impregnating with the above synthetic resin will cause the fiber material to fall off during washing and dyeing, and the effect exhibited by each of the above synthetic resins will not be exhibited after washing or decoloration, or significantly reduced. However, when the synthetic resin is combined with the fiber material, the synthetic resin does not fall off even during washing and dyeing, and the effect can continue to be exhibited thereafter.

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 is bonded to the fiber material, thereby exhibiting sufficient water repellency after washing and dyeing.

  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 does not fall off even during washing and dyeing, and in a bath immersed in water, it is more dry. Can also soften the fiber material. Thereby, the strength fall of the said fiber raw material and a thrash can be prevented. This effect is particularly suitably exhibited when the fiber material is a cellulose material that becomes very hard when wet.

  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, oil It can be used as a fiber material that is resistant to dirt.

  Specifically, the post-dyed fiber material according to the present invention can achieve a water repellency grade of 2 or higher as a result of the water repellency test described in JIS L 1092, and is preferably a material that achieves this value. If it is the first grade, 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 with a water-repellent spray etc. There is a need to do. In addition, in that case, there is no durability of water repellency, the texture becomes hard, and when the fiber material is a synthetic fiber such as polyester, there is a problem that the fastness to friction is lowered. The maximum grade is grade 5, and it is rare that grade 4 or higher is required except when the fiber material is a coat, but grade 5 may be used. Products with water repellency of grade 4 or grade 5 can be achieved by adjusting the concentration ratio of the chemicals used. The fiber material for post-dying according to the present invention does not cause a problem in dyeability even if the above water repellency is achieved.

  The fiber material for post-dyeing according to the present invention has an oil repellency as a result of the oil repellency test described in AATCC (American Association of Textile Chemists and Colorists, American Textile Chemist / Color Engineer Association) 118-2002. It is preferable to achieve the first grade (corresponding to a surface tension of 32 dyne / cm or less) or higher, preferably to achieve this value, more preferably second grade or higher, and more preferably third grade or higher. If it is not first grade, the oil repellency is insufficient and oleic acid contained in human sweat oil corresponding to the first grade is attached. It is more preferable to satisfy the third grade (corresponding to 27.3 dyne / cm or less) because oil contamination of about n-hexadecane can be prevented. The fiber material for post-dying according to the present invention does not cause a problem in dyeability even if the above oil repellency is achieved. The maximum grade is 8th grade, but since the surface tension of silicon resin is 24 dyne / cm and the surface tension of fluororesin is 10 dyne / cm, when these are used in combination, oil repellency grade 8 Since it is practically difficult to realize (19.8 dyne / cm), it is realistic that it is actually 7th grade or less.

  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 production procedure. Since this value is smaller than ordinary polyester fibers and smaller than most oils, most oil stains can be easily wiped without penetrating into the fiber material for post-dyeing according to the present invention. . Moreover, this surface tension is so preferable that it is small. The surface tension of ordinary polyester not bonded in the present invention is 45 dyne / cm and nylon is 60 dyne / cm, whereas the surface tension of water is 70 dyne / cm.

  Furthermore, the fiber material for post dyeing concerning this invention can improve the result in the moisture permeability test described in JIS L 1099A-1 more than the fiber material which does not process. Moisture permeability is not directly related to dyeability, but exhibits a beneficial effect of absorbing sweat and the like when a post-dyed fiber material obtained with good moisture permeability is used for clothes or the like. Such good moisture permeability is established even if the water repellency is high. This is because the water vapor that is the object of hygroscopicity is smaller than the liquid water that is the object of water repellency, and these 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, but in the present invention, the moisture permeability can be improved.

  On the other hand, the fiber material for post-dying according to the present invention can improve the water absorption of the fiber material for post-dyeing by selecting only the copolymer resin or the water-absorbing polyester resin as the synthetic resin to be imparted.

  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. Moreover, although the said copolymer resin is inferior to the said acrylate resin in surface tension, since it is hydrophilic in a dry state, the effect which repels oil is high. Furthermore, since the copolymer resin is hydrophilic in water such as during dyeing and washing, it improves the washing effect and easily removes dirt, and also has the effect of improving dye adsorption during dyeing. Also, the effect of increasing hygroscopicity is exhibited. On the other hand, since the acrylate resin does not have a hydrophilic group, the effect of improving water repellency is high.

  In the fiber material for post-dyeing according to the present invention, at least one of the water repellency and oil repellency values can be easily achieved, and in particular, the content of the acrylate resin or the copolymer resin can be adjusted. Both values can be easily satisfied. That is, water repellency can be improved by the acrylate resin, and moisture permeability can be improved by the copolymer resin. By combining these synthetic resins with the fiber material, for example, it is possible to play clothes such as rainwater while being able to take out moisture from internal sweat.

  When dyeing the fiber material for post-dyeing according to this invention, depending on the shape of the fiber material, it can be processed under any conditions suitable for them, and the dyeing means is not particularly limited. Absent. Specifically, any dye such as a dispersible dye, an acid dye, a reactive dye, a direct dye, a vat dye, or a basic dye can be used as the dye.

  As a dyeing method, any method such as dip dyeing or cold patch dyeing can be used. When the fiber material is a spun yarn or a filament yarn, a casserole processing machine, a cheese processing machine, a rope processing machine, a slasher processing machine, etc. may be used. Or a cold patch dyeing machine may be used. In addition, when the fiber material is a knitted fabric other than polyester, wins may be used, and for dyeing woven fabrics and nonwoven fabrics, a zicker dyeing machine or a pad batch dyeing machine may be used. In addition, when dyeing textile materials after sewing, the shape of the sewn product may be damaged if a drum dyeing machine is used, or if a dyeing machine for dip dyeing, such as a normal pressure washer or a high pressure washer, is used. It is preferable because it is difficult.

  The post-dyeing fiber material obtained by post-dying the post-dyeing fiber material according to the present invention has a water repellency test result of JIS L 1092, which is sufficiently dried after post-dying, and has a grade of 5 or higher. It is preferable that the state below grade can be maintained even after dyeing. The high water repellency after dyeing means that the synthetic resin does not fall off during dyeing, and is strongly integrated with the fiber material by intermolecular bonding, indicating high durability. is there. If these values can be achieved, it is not necessary to apply a water repellent by spraying, which has been practiced after dyeing, and the product should be suitable for high-quality pants, jackets, coats, car seats, and interior materials. become.

  Further, the dyed fiber material has a result of the oil repellency test described in AATCC 118-2002 of preferably 2nd grade or more, and more preferably 3rd grade or more. If it is 1st grade or less, the oil repellency is insufficient and it becomes extremely weak against oil stains. The standard is that oil repellency grade 2 has a surface tension of 29.6 dyne / cm and is less than 32 dyne / cm of sweat oil (oleic acid), so oil repellency of grade 2 or higher is required at a minimum. This is because if it is 3rd grade or higher (27.3 dyne / cm), it is effective against almost oily soil. On the other hand, it is preferable that it is 7th grade or less. As above, Grade 8 is difficult due to the limit of oil repellency.

  Furthermore, when the post-dyeing fiber material is 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, and 29.6 dyne / cm or less. Is more preferable. This is because if it exceeds 31.5 dyne / cm, oleic acid, which is a component of sweat oil, tends to adhere. 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. Even if the amount of use is reduced, an equivalent 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.

  Note that these water repellency, oil repellency, and surface tension values are easily achievable when normal dyeing is performed using the post-dyeing fiber material according to the present invention, and all values are satisfied. It is more preferable. In particular, when an acrylate resin having a perfluoroalkyl group or a copolymer resin having an acrylate unit having a perfluoroalkyl group and a hydrophilic vinyl monomer unit is used as the synthetic resin, the surface tension is 29.6 dyne / It can be easily reduced to cm or less. Such a fluorine-containing resin has a surface tension of about 10 dyne / cm when it is in the form of a film, and exhibits very fast oil repellency, but it does not reach that value when it is intermolecularly bonded to the fiber material. . Accordingly, it is preferable to copolymerize with a hydrophilic vinyl monomer to exert an 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 vinyl monomer is only about first grade, these effects complement each other when a copolymer resin with an acrylate having a perfluoroalkyl group is used. This is a preferable resin.

  With respect to 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.

  The post-dyeing fiber material according to the present invention is excellent in water repellency and oil repellency as it is, but after the post-dyeing, further water repellency, oil repellency, fastness improvement, antibacterial, antistatic, extinguishing Processing such as odor may be performed. Even during these processes, since the fibers are integrated with the synthetic resin, the fibers are hardly 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.

  As described above, for a fiber material containing at least one of a hydroxyl group, an amino group, an amide group, a carboxyl group, or a urethane group, the dyeing property of the fiber material is improved by reacting with the functional group of the fiber material. By performing a processing process that includes a resin solution containing a synthetic resin as a main component, the water repellency, oil repellency, and surface tension of the fiber material satisfy the above conditions even after washing, and have high dyeability and durability to washing. It is possible to produce a fiber material for post-dyeing with high properties.

This was dried for 1 minute in an environment of 130 ° C., and then heat-treated at 180 ° C. for 60 seconds using the same baking machine as in Example 1. The polyester fabric, which is a fiber material for post-dying obtained in this way, was dyed and subjected to reduction washing 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. When the K / S value is expressed as a relative value, if Comparative Example 11 is 100, Reference Example 1 is 104.9.

(Reference Examples 3-5)
The same polyester fabric as in Reference Example 1 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” represents SM-Cube SS, “KL” represents SM-Cube KL, and “SRM-65” represents Meika Finish SRM-65, which is a polyester resin solution. Each resin solution was applied to a fiber material at a pickup rate of 60% using a Pad-Dryer tester manufactured by Sakurai Seisakusho.

  After drying in an environment of 120 ° C., heat treatment was performed at 160 ° C. for 2 minutes with a baking tester manufactured by Shimadzu Corporation. Each of the polyester fabrics, which are the fiber materials for post-dyeing obtained in this way, was subjected to a test high-pressure dyeing machine (manufactured by TEXAM) for 60 minutes at a bath ratio of 1:15 at 130 ° C.

For this reason, it turned out that oil repellency and water absorption can be adjusted by adjusting content of SRM-65 which is a polyester resin solution. In addition, polyester fibers that have been used in the conventional dyeing process have been deteriorated by subsequent dyeing even if oil repellency and water absorption have been imparted, and the method according to the present invention reduces the dyeing density in the subsequent dyeing. In addition, the post-dyeing could be carried out without lowering the oil repellency and water absorption.

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

  Then, neutralize with a 60 ° C solution containing 2 g / L of soda ash for 10 minutes, wash in 60 ° C water for 10 minutes, and finally dry in an environment of 120 ° C for 2 minutes. Processed. 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-0217 103 method, and then evaluated for water repellency and oil repellency.

(result)
In Comparative Example 14 by 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 14, which is a fiber material for post-dying processed with the resin solution according to the present invention, the oil repellency and water repellency were hardly lowered even after the washing durability test.
