[0001] The present invention relates to a method for manufacturing a supported glove. [Background technology]

[0002] Conventionally, gloves for home and work use have been coated with polymers such as rubber or resin on the surface of knitted gloves. Support type gloves on which a coating (hereinafter referred to as a polymer coating) is formed are known (for example, For example, see Patent Document 1 below. Such support gloves are mainly described in the following Patent Document 1: It is manufactured according to the following procedure: (1) The knitted gloves are placed in a coagulant solution (e.g., a salt coagulant containing 20% ​​by mass of calcium nitrate).

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2001-89912 Summary of the Invention [Problem to be solved by the invention]

[0004] As described above, after immersing the knitted glove in the polymer suspension, the glove is dried. Therefore, when a polymer coating is formed, the following problems arise.

[0005] First, in order to make it difficult for the polymer coating to peel off from the knitted gloves, When the polymer suspension is sufficiently permeated, the inner surface of the resulting support type glove is The polymer coating is formed on the surface of the substrate. In this way, when the polymer coating is formed on the inner surface side of the support type glove, When wearing a support glove, the wearer's hand is caught on the inner surface of the support glove. In addition, when the support type glove is worn, the wearer's hand is in contact with the support type glove. It may stick to the inner surface. In this way, when wearing the support type gloves, the hand does not get caught on the inner surface or the inner surface It is undesirable for the wearer to have their hands stick to the surface, as this can be uncomfortable.

[0006] On the other hand, the wearer's discomfort when wearing the support type gloves is suppressed. From this viewpoint, it is considered that the polymer suspension is not allowed to penetrate to the inner surface side of the knitted glove. can be done. The support type gloves obtained in this way do not cause discomfort to the wearer when worn. However, the polymer coating is formed on the inner surface of the knitted glove. Therefore, when using such a supported glove, the polymer coating is This makes it easier to peel off from the glove. In this way, the support type gloves prevent the wearer from feeling uncomfortable when wearing them. and suppressing the polymer coating from easily peeling off from the knitted glove. are in a trade-off relationship.

[0007] However, in order to resolve the above trade-off relationship in support gloves, However, it is difficult to say that sufficient consideration has been given to this issue.

[0008] In view of the above problems, the present invention aims to prevent the wearer from feeling uncomfortable when wearing the garment, The support can also prevent the polymer coating from peeling off easily from the knitted gloves. The objective of the present invention is to provide a method for manufacturing a glove. [Means for solving the problem]

[0009] The method for producing a support glove according to the present invention comprises the steps of: A first polymer mixed liquid containing a first liquid and a first polymer, wherein the first polymer is 0. A first polymer mixture containing 2% by mass or more and 4.0% by mass or less is A first polymer applied to at least a portion of a knitted glove knitted using yarn of 0 dtex or less - a mixed liquid application step; a first drying step of drying the knitted glove after the first polymer mixture application step; a coagulant solution applying step of applying a coagulant solution to the knitted glove after the first drying step; A second polymer mixture liquid containing a second liquid and a second polymer, The second polymer mixture solution containing 65% by mass or more and 65% by mass or less is applied to the knitted fabric after the coagulant solution application step. A second polymer mixture is applied to at least a portion of the area of ​​the glove where the first polymer mixture is applied. a polymer mixture coating step; A second drying step of drying the knitted glove after the second polymer mixture application step. death, The yarn used to knit the knitted glove is covered over the entire thickness direction of at least a part of the knitted glove. The first polymer mixture application step and the first polymer mixture application step are carried out so as to form a first polymer coating. A drying process is carried out, A second polymer is used to form at least a portion of the outer surface of the knitted glove when worn. - Forms a coating and extends from the outer surface to the inner surface of the knitted glove when worn. The second polymer coating continuously covers the first polymer coating without reaching the inner surface. The coagulant solution applying step, the second polymer mixed solution applying step, and The second drying step is carried out.

[0010] According to this configuration, in the first polymer mixed solution applying step, The first polymer mixture solution containing the first polymer at a relatively low concentration of 0.2% by mass or more and 4.0% by mass or less and applying the coating to at least a part of a knitted glove knitted with yarn having a fineness within a predetermined range. and each yarn knitting the knitted glove throughout the entire thickness direction of at least a part of the knitted glove. The first polymer mixture liquid can be applied in a state where it thinly covers the surface of the substrate. Therefore, when the first polymer mixture application step and the first drying step are performed, A table of each yarn knitting the knitted glove throughout the thickness direction for at least a portion of the knitted glove. The first polymer coating is formed in a thin coating state on the surface. In addition, both the first polymer coating and the second polymer coating are formed of polymers. It is a compound that has a relatively high affinity. Therefore, the coagulant solution is applied so as to form the second polymer film as described above. When the step, the second polymer mixture application step, and the second drying step are performed, The second polymer film can be formed in a state where it is sufficiently adhered to the first polymer film. . Furthermore, the second polymer coating is formed so that it is not exposed from the inner surface when worn. It is possible. Furthermore, the second polymer mixture liquid has a relatively high concentration of 20% by mass or more and 65% by mass or less. Since the second polymer is contained in the fabric at a high concentration, the second polymer coating provides a good resistance to wear. The outer surface can be made thick enough. As a result, when wearing the resulting support glove, the wearer's hand moves in contact with the support glove. The support type glove may be caught on the inner surface of the bag or may be attached to the wearer's hand when the support type glove is worn. may stick to the inner surface of the support glove, causing discomfort and unnecessary irritation to the wearer. This can be suppressed. In addition, the second polymer coating is formed so as to be difficult to peel off from the knitted glove. can. That is, the resulting support type gloves are designed to prevent the wearer from feeling uncomfortable when wearing them. This prevents the polymer coating from peeling off easily from the knitted gloves. can.

[0011] Further, in the method for producing the support type glove, The first polymer mixture liquid is a latex in which the first liquid is water, A coagulant solution is applied to the knitted glove before the first polymer mixture application step. It is preferable to further carry out a coating step.

[0012] The water contained in latex as a dispersion medium (solvent) is less volatile than organic solvents, Water tends to remain in the knitted gloves after the first polymer mixture application step, and this makes it possible to Pipe phenomenon is likely to occur. When capillary action occurs in the water remaining in the knitted gloves, this water is absorbed into the knitted gloves. The first polymer mixture moves through the knitted glove along each yarn, and the latex In the case of latex, the first polymer particles contained in the latex as polymer particles move with the movement of water. The polymer also becomes mobile. As a result, when the first polymer mixture is latex, Through the coating process and the first drying process, the polymer particles contained in the knitted gloves The distribution of the first polymer becomes uneven, and a relatively uniform polymer coating is formed. It becomes more difficult to do so. However, according to this configuration, before the first polymer mixture application step, Since a coagulant solution application step is performed in which the gloves are immersed in the coagulant solution, This allows the first polymer to solidify and remain in place within the knitted glove. do. This makes it possible to prevent the first polymer from being distributed unevenly, The first polymer coating can be formed relatively uniformly.

[0013] Further, in the method for producing the support type glove, The coagulant solution applied to the knitted glove before the first polymer mixture application step is 0.01 It is preferable that the salt coagulant is contained in an amount of from 0.5% by mass to 0.5% by mass.

[0014] In the conventional coagulation method using a salt coagulant, the polymer mixture solution was The purpose is to quickly form a polymer coating without reaching the surface. A coagulant solution containing a relatively high concentration of salt coagulant is used. In contrast, the above-mentioned configuration is such that the first polymer mixture solution is contained in the knitted glove when worn. The first polymer coating is then solidified to the inner surface. Since it is employed for the purpose of forming, the concentration of salt coagulant in the coagulant solution is 0. The concentration is extremely low, between 0.1% and 0.5% by mass. Therefore, the coagulant solution can be sufficiently permeated into the knitted glove. This further prevents uneven distribution of the first polymer in the knitted glove. This allows the first polymer coating to be more uniformly formed in the knitted glove. It is possible. In addition, the coagulant solution to be applied to the knitted glove before the first polymer mixture application step Since the concentration of the salt coagulant is relatively low, at 0.01% by mass or more and 0.5% by mass or less, The adverse effects of the salt coagulant on the fibers constituting each yarn forming the bag are It can be made small. For example, deterioration of fibers caused by salt coagulants can be suppressed. [Effects of the Invention]

[0015] As described above, according to the present invention, it is possible to suppress discomfort felt by the wearer when wearing the garment, The support can also prevent the polymer coating from peeling off easily from the knitted gloves. A method for manufacturing a glove can be provided. [Brief explanation of the drawings]

The fineness of the yarn used for knitting the knitted glove 10A is preferably 167 dtex, It is more preferable that the thickness is 154 dtex or less, and even more preferable that the thickness is 144 dtex or less. preferable. Furthermore, the fineness of the yarn used to knit the knitted gloves 10A is 33 dtex or more and 180 dtex x or less, the yarn is more fully covered (more specifically, the fibers constituting the yarn). The first polymer coating can be formed on the surface of the substrate (more completely covering the surface of the substrate). The fineness of the yarn used to knit the knitted glove 10A is the fineness of the yarn used to knit each course of the knitted glove 10A. For example, the total fineness of the yarns used in knitting one course of knitted gloves 10A is When several yarns are used, the total fineness is the sum of the finenesses of the individual yarns. In addition, inlay knitting, in which weft threads such as rubber are inlaid into the base knitted fabric, is also being practiced. In the case where the inlay knitting is performed, the weft yarn used for the inlay knitting is This does not include.

[0026] The knitted glove 10A can be produced by various known methods, for example, using a glove knitting machine. It can be made by knitting yarns.

More preferably, the glove knitting machine has a gauge of 21 or more. The glove knitting machine preferably has a gauge of 26 or less. By keeping the gauge number at 26 or less, the resulting knitted gloves have high strength. do. As a method for manufacturing the knitted glove 10A other than using a glove knitting machine, for example, After obtaining a pair of glove-shaped knitted fabrics, the pair of glove-shaped knitted fabrics are sewn together. Thus, a knitted glove can be obtained. On the other hand, the sewing method mentioned above requires extra costs such as sewing fees. Therefore, the method for producing the knitted glove 10A is preferably a method using a glove knitting machine. A method of forming seamlessly knitted gloves using a knitting machine is more preferred. The knitted glove 10A can be knitted by various known methods, such as flat knitting. Examples of knitting include knitting. The knitted glove 10A is manufactured by knitting a plurality of yarns in a parallel arrangement.

[0028] The polymer coating 10B is a first polymer formed over the yarn that knits the knitted glove 10A. It is provided with a coating 10B1. The first polymer coating 10B1 is formed on the entire thickness of at least a part of the knitted glove 10A. The glove 10A is knitted by covering the yarn (more specifically, the surface of the fiber constituting the yarn). are. On the palm side of the support type glove 1 according to this embodiment, the first polymer coating 10B1 is The entire outer surface of the knitted glove 10a and a part of the outer surface of the hem 20 are It is formed by covering the yarn that knits the fabric (more specifically, by covering the surface of the fibers that make up the yarn). At the same time, the entire outer surface of the first finger portion 10b1 to the fifth finger portion 10b5 is It covers the yarn that knits the knitted glove 10A (more specifically, it covers the surface of the fiber that makes up the yarn). ) is formed. In addition, on the back side of the support type glove 1 according to this embodiment, the first polymer coating 10B1 The first finger portion 10b1 to the fifth finger portion 10b5 are aligned along the side edges of the main bag portion 10a. Also, the yarn for knitting the knitted glove 10A is distributed over the entire thickness along the crotch area between each finger. The first finger of each finger is formed on the surface of the yarn (more specifically, on the surface of the fibers that make up the yarn). The yarn used to knit the knitted glove 10A throughout the thickness direction on the fingertip side of the part corresponding to the two joints (more specifically, covering the surface of the fibers that make up the yarn). The polymer coating 10B is formed on at least the outer surface of the knitted glove 10A when worn. The knitted glove 10A is formed to constitute a part of the inner surface of the knitted glove 10A in a worn state. The first polymer coating 10B1 is formed continuously covering the surface without reaching the inner surface. The second polymer coating 10B2 is formed on the surface of the substrate 10B. In the support type glove 1 according to this embodiment, the second polymer coating 10B2 is formed on the palm side and the On the back side, it is formed in a location that overlaps with the location where the first polymer coating 10B1 is formed. From the viewpoint of ease of manufacturing, the area where the first polymer film 10B1 is formed is It is preferable that the area is wider than the area where the coating 10B2 is formed.

[0029] Hereinafter, with reference to FIGS. 2(a) and 2(b), the formation mode of the polymer coating 10B will be described. A more detailed explanation will be given below. Note that Fig. 2(a) shows a cross section of the palm portion, and Fig. 2(b) shows , an enlarged portion of FIG. 2(a) is shown.

[0030] The knitted glove 10A is made by knitting a yarn 10A1 made of fibers 10A1a. As shown in the cross section of FIG. 2(a), in the knitted glove 10A, In other words, a gap is generated between adjacent threads 10A1. As described above, the first polymer coating 10B1 is a film that protects the yarn 10A1 from the knitted glove 10A. (more specifically, covering the surface of the fiber 10A1a constituting the thread 10A1) are. Therefore, in the state where the first polymer coating 10B1 is formed on the knitted glove 10A, As a result, voids are formed in the path from the outer surface to the inner surface of the knitted glove 10A. As shown in FIG. 2(a), the second polymer coating 10B2 is formed on at least the outer surface of the and forms a part of the knitted glove 10A from the outer surface to the inner surface. The first polymer film 10B1 is formed so as to cover the first polymer film 10B1 without reaching the first polymer film 10B1. That is, the second polymer film 10B2 is formed on the knitted glove 10A as shown in FIG. It is formed to a depth that does not reach the inner surface. In the support type glove 1 according to this embodiment, as shown in FIG. 2(a), The yarn coating 10B2 is formed from the outer surface of the knitted glove 10A to the adjacent yarns 10A in the knitted glove 10A. 1 It is formed by being packed between two adjacent particles. That is, the second polymer coating 10B2 is formed as a dense coating. Here, as shown in FIG. 2(b), the yarn 10A1 for knitting the knitted glove 10A is The fibers 10A1a are adjacent to each other in a state where the first polymer coating 10B1 covers the surface of the fibers 10A1a. It is preferable that there are gaps between at least some of the fibers 10A1a. By providing a gap between at least a portion of the adjacent fibers 10A1a, the gap The second polymer coating 10B2 can be formed so as to fill the gap between the yarn 10A1 and the second polymer coating 10B2. The adhesion of the polymer coating 10B2 is more sufficiently ensured through the first polymer coating 10B1. You will be able to do this. Since it is easy to form gaps between at least some of the adjacent fibers 10A1a, the yarn 10A As the material 1, it is preferable to use a filament yarn. In the knitted glove 10A, the outer surface refers to the surface that is on the outside when worn. The inner surface is the surface that is on the inside when worn (the surface that comes into contact with the wearer's hand). As described above, in the support type glove 1 according to this embodiment, the polymer coating 10B is formed Two types of polymer coatings with different configurations (first polymer coating 10B1 and second polymer coating 10B2) 0B2).

[0031] As the polymer for forming the first polymer film 10B1, various known polymers can be used. It can be used. The polymers include natural rubber (NR), acrylonitrile-butadiene copolymer ( NBR), polychloroprene, polyisoprene, (meth)acrylic acid ester copolymer, and polyurethane (PU). Natural rubber (NR), acrylonitrile butadiene copolymer (NBR) particles, poly Chloroprene particles, polyisoprene particles, and (meth)acrylic acid ester copolymer particles The molecule may be carboxy-modified. These various polymers may be used alone or in combination. This may also be done. The first polymer coating 10B1 may also contain various compounding ingredients. Various compounding agents include vulcanizing agents such as sulfur; zinc dimethyldithiocarbamate; and zinc oxide. Vulcanization accelerators such as epoxides, oxazolines, carbodiimides, isocyanates, etc. Functional crosslinkers; plasticizers and softeners such as mineral oils and phthalates; 2,6-t antioxidants and anti-aging agents such as 4-butyl-4-methylphenol; acrylic polymers and poly Thickeners such as sugars; foaming agents such as azodicarbonamide; sodium stearate Foaming agents and foam stabilizers; anti-tack agents such as paraffin wax; carbon black, calcium carbonate Examples of fillers and pigments include sodium, finely divided silica, etc. The polymer for forming the second polymer coating 10B2 is the same as the above polymer. The second polymer film 10B2 can be formed using the same polymer as the first polymer film 10B1. The above-mentioned various compounding agents may be contained in the above-mentioned composition.

[0032] In the case of conventional support gloves, a relatively high concentration of coagulant solution is impregnated into the knitted gloves. Then, a polymer coating is formed using a relatively high concentration polymer mixture by the salt coagulation method. Therefore, the inside of the thread (the gap between the fibers that make up the thread. In other words, multiple fibers are gathered together. The coagulant solution and the polymer mixture can be sufficiently permeated into the gaps between the fiber bundles. I couldn't. Therefore, in conventional support gloves, the polymer coating is used to ensure that the material penetrates deep into the yarn. It was difficult to form a film. In contrast, in the support type glove 1 according to this embodiment, the first polymer coating 10B1 is The polymer for forming the first polymer coating 10B1 penetrates into the gaps between the fibers 10A that constitute the thread 10A1. It is formed so as to cover the surface of 1a. Therefore, the polymer for forming the first polymer coating 10B1 penetrates (soaks into) the gaps between the fibers 10A1a. As a result, a good anchoring effect is exerted by the polymer that has penetrated (soaked into) the gaps between the fibers 10A1a, so that the first polymer coating 10B1 can be sufficiently adhered to the thread forming the knitted glove 10A. Also, as described above, the second polymer coating 10B2 covers the first polymer coating 10B1. And both the first polymer coating 10B1 and the second polymer coating 10B2 are formed of polymers, and they have relatively high affinity. From the above, as described above, by sufficiently adhering the first polymer coating 10B1 to the thread forming the knitted glove 10A, the adhesion of the second polymer coating 10B2 to the thread is sufficiently ensured through the first polymer coating 10B1. From the viewpoint of improving the adhesion of the second polymer coating 10B2 to the first polymer coating 10B1, the polymer for forming the first polymer coating 10B1 and the polymer for forming the second polymer coating 10B2 are preferably of the same type. When the polymer for forming the first polymer coating 10B1 and the polymer for forming the second polymer coating 10B2 are of different types, if the solubility parameters (SP values) of the fiber constituting the thread, the first polymer, and the second polymer are respectively SP1, SP2, and SP3, then the relationship of SP1 < SP2 < SP3, or the relationship of SP3 < SP2 < SP1. [[ID=2l]] ​​​​​​​​​​​​It is preferable that the relationship be satisfied. By satisfying such a relationship, the yarn through the first polymer coating 10B1 This can further improve the adhesion of the second polymer film 10B2 to the substrate.

This can improve ease of attachment and detachment. In addition, by making the content 0.2 mass % or more, the second polymer coating film becomes more easily peeled off. Furthermore, it is possible to prevent the tear resistance from decreasing. The solid content of the first polymer is added to the organic solvent so as to be 4.0 mass % or less. It is preferable that By the fact that the content of the knitted hand is 4.0 mass % or less, in the obtained support type glove, The gripping force of the inner surface of the bag becomes too high, and the inner surface of the knitted glove is This increases the grip on the surface, reducing discomfort felt by the wearer. .

For example, a methanol solution or an aqueous solution containing a polyvalent metal salt or an organic acid can be used. . As the second coagulant solution, it is preferable to use a solution containing the polyvalent metal salt. The second coagulant solution contains the polyvalent metal salt, and thus the second polymer This can prevent the mixed liquid from excessively penetrating into the knitted glove.

[0053] Examples of the polyvalent metal salt include barium chloride, calcium chloride, magnesium chloride, and zinc chloride. Lead, aluminum chloride, barium nitrate, calcium nitrate, zinc nitrate, barium acetate, acetic acid Examples include calcium, zinc acetate, calcium sulfate, magnesium sulfate, and aluminum sulfate.

This results in the formation of a second polymer coating on the inner surface of the resulting supported glove. can be suppressed. As a result, the grip strength of the inner surface of the knitted glove is high in the resulting support glove. The inner surface of the knitted glove is likely to get caught on the support glove when the support glove is put on or taken off. The second polymer coating may become too thick or may partially penetrate the skin, causing irritation to the wearer's fingers.

In this way, by subjecting the second polymer mixture to mechanical foaming treatment, the second polymer mixture can be The second polymer coating film formed by the drying step S6 can be a porous coating film. The second polymer coating has excellent flexibility. In addition, when the second polymer mixed solution is not subjected to mechanical foaming treatment, The coating becomes a non-porous coating.

The first polymer coating 10B1 is formed continuously covering the surface without reaching the inner surface. will be done. That is, the second polymer coating is formed to a depth that does not reach the inner surface of the knitted glove. It is being done. The second polymer coating is formed between adjacent yarns in the knitted glove in a packed state. can be. In the second drying step S6, a crosslinking agent or an additive is added to the first polymer film and the second polymer film. When a vulcanizing agent is included, the second polymer coating and the second polymer coating are crosslinked. Further heating may be carried out to drive the reaction forward. The heating temperature for promoting the crosslinking reaction is, for example, 90°C or higher and 150°C or lower. The heating time may be, for example, 10 minutes or more and 60 minutes or less.

[0074] <Support gloves> The support type glove in each example was prepared by mixing the knitted glove shown in Table 1 above, the first coagulant solution, the first polymer The second coagulant solution and the second polymer mixture were used as follows: Made.

[0075] After placing the knitted gloves on a metal three-dimensional hand mold (hand mold for dipping processing), The mixture was heated in an atmosphere of 70°C. Next, the third finger portion is adjusted so that the extension direction of the third finger portion and the liquid surface of the first coagulant solution form an angle of 5 to 20 degrees. The entire outer surface of the palm side of the bag portion of the knitted glove, a part of the outer surface of the palm side of the hem portion, And the entire outer surface of the palm of the first to fifth fingers, and the area from the fingertips to the first fingers on the back of the hand The area up to the joint is immersed in the first coagulant solution from the fingertip side, and the first coagulant solution is applied. After that (first coagulant solution application step), the knitted glove is pulled out from the first coagulant solution, The methanol was partially evaporated by drying at 25°C for 30 seconds. Next, in the same manner as described in the first coagulant solution application step, the first coagulant solution is applied to the The knitted glove after coating is immersed in the first polymer mixture solution. After the first polymer mixture is applied (first polymer mixture application step), the knitted glove is The hand mold was then removed from the oven and dried in an oven at 75°C for 20 minutes (first drying step). A first polymer coating was formed on the knitted glove. Next, the knitted glove on which the first polymer coating was formed was heated in an oven at 60°C. After adjusting the temperature, the first polymer is applied in the same manner as described in the first coagulant solution application step. The knitted glove on which the coating has been formed is immersed in a second coagulant solution to coat the second coagulant solution. Then, the knitted glove is removed from the second coagulant solution (second coagulant solution application step). The mixture was heated and dried at 25°C for 30 seconds to evaporate some of the methanol. Next, in the same manner as described in the first coagulant solution application step, the second coagulant solution is applied. The knitted glove after the fabrication process is immersed in a second polymer mixture to coat the second polymer mixture. After the knitted glove is woven (second polymer mixture application step), the knitted glove is The hand mold is then removed and dried in an oven at 75°C for 10 minutes, and then heated to 120°C. The knitted gloves were dried in an oven for 40 minutes (second drying step). A polymer coating was formed. In order to absorb manufacturing errors, the first polymer mixture coating step is performed using the first solidification The first polymer mixture is applied so that the area is slightly narrower than the area where the second coagulant solution is applied. In the liquid application process, the second coagulant solution is applied to a slightly wider area than the first polymer mixture liquid. In the second polymer mixture application step, the second polymer mixture is applied to the first polymer mixture. The liquid was applied so that the area was slightly narrower than the area to be applied. Next, the hand mold is cooled to 25°C, and then the first polymer coating and the second polymer coating are removed from the hand mold. The support type glove according to each example is obtained by pulling out the knitted glove on which the liner coating is formed. Got it. In the example shown as blank in the first coagulant solution section of Table 1, the first coagulant solution The liquid application process was not carried out, and the first polymer mixture liquid was left blank. In this example, a support type glove is produced without carrying out the first polymer mixture application step and the first drying step. Made.

[0076] <Whether the second polymer coating is exposed from the inner surface> For the support type gloves according to each example, the second polyamide from the inner surface (the surface that comes into contact with the wearer's hand) The presence or absence of exposure of the mercap was evaluated. The presence or absence of exposure of the second polymer coating from the inner surface was evaluated by visual observation. Specifically, when the inner surface of the support type glove according to each example is visually observed, the second If the polymer coating does not reach the inner surface, it is evaluated as "absent" and the second polymer coating is evaluated as "absent." The membrane is formed so that it is flush with the inner surface, or it extends beyond the inner surface ( If the protective layer was formed (even on the wearer's hand side), it was evaluated as "present." The results are shown in Table 2 below.

[0077] <Peel strength> The peel strength of the second polymer coating was measured for each of the supported gloves. The peel strength of the second polymer coating was measured as follows. (1) Testing a narrow strip of 25 mm wide x 100 mm long from the palm of the support-type glove in each example Collect a piece. The test piece shall be collected such that the longitudinal direction is the same as the extending direction of the third finger (middle finger). Collect it. (2) At one end side in the longitudinal direction of the test piece, peel off a part of the second polymer film from the knitted glove. Peel it off. (3) After setting the chuck distance between the two chucks of the tensile testing machine to 40 mm, attach the knitted glove part at one end side of the test piece to one chuck, and attach the second polymer film part at the other end side of the test piece to the other chuck. Attach the knitted glove part at one end side of the test piece to one chuck, and attach the second polymer film part at the other end side of the test piece to the other chuck. Attach the second polymer film part at the other end side of the test piece to the other chuck. (4) When performing a 180° peel test at a tensile speed of 50 mm / min and a travel distance of 100 mm, obtain the average value of the peaks of the plurality of mountains and the peaks of the plurality of valleys of the test force (tensile force) observed. Obtain the average value of the peaks of the plurality of mountains and the peaks of the plurality of valleys of the test force (tensile force) observed. Obtain it. The above measurement was carried out on four test pieces. Also, the peel strength was determined as the value obtained by calculating the arithmetic mean of the test force values obtained for the four test pieces. It was set as the value obtained. The results are shown in Table 2 below.

[0078] <Tear strength> For the support-type gloves according to each example, the tear strength (unit: N) was measured in accordance with EN388. Measure it. The results are shown in Table 2 below.

[0079] <FT-IR analysis> For the support-type gloves according to each example, test pieces were collected from the fingertip part and the center part of the palm of the third finger (middle finger), and the inner surface side (the side in contact with the wearer's hand) of these test pieces was analyzed by FT-IR (ATR method). By FT-IR measurement, spectral data in the range of 500 to 3500 cm -1 accumulated 256 times was obtained. For comparison, the first polymer coatings prepared in petri dishes, i.e., NBR coating, NR coating, acrylic polymer coating, and PU coating, were also measured in the same manner as above, and the characteristic peaks of the first polymer coatings were obtained from the spectral data. The data of each test piece taken from the support-type glove of each example was compared with the data of the first polymer coating as a comparison, and the presence or absence of the first polymer coating on the inner surface was confirmed from the major signal (peak). The results are shown in Table 2 below. In addition, in the following Table 2, Examples 2, 5, 7, and 8 are listed. ,fruit Example 10 , and Comparative Example 3 FT-IR analysis results are shown.

[0080] <Dynamic friction coefficient> A strip of 6.4 cm wide x 10 cm long was cut from the center of the palm of the support-type glove in each example. Test specimens were taken. The test piece is collected so that the length direction of the test piece is the same as the extension direction of the third finger. did. According to ASTM D 1894, the contact area dimensions are 6.4 cm x 6.4 cm; The test piece was attached to a 200g friction piece and placed on a horizontally placed mirror-finished steel plate. The test force (tensile force) was measured when the stainless steel plate was pulled at a speed of 150 mm / min. The coefficient of kinetic friction of the specimen was determined. The above measurements were carried out on four test pieces. In addition, the average dynamic friction coefficient was calculated by arithmetically averaging the dynamic friction coefficients obtained for the four test pieces. The friction coefficient was calculated. The results are shown in Table 2 below.

[0081] <Inner surface discomfort> For the support-type gloves according to each example, discomfort caused by the inner surface when worn We checked whether or not this was the case. Regarding the presence or absence of discomfort, if there was no discomfort at all, it was rated as "none," and if there was some discomfort, it was rated as "somewhat uncomfortable." If the discomfort is tolerable, it is rated as "a little unpleasant." If the discomfort is obvious and unbearable, it is rated as "unbearable." Cases with only a moderate degree of difficulty were evaluated as "yes." The results are shown in Table 2 below. The results shown in Table 2 are the results of the evaluation by the largest number of five panelists. This is what has been described.

[0082] [Table 2]

[0083] In the support type gloves according to each example, the peel strength value exceeded 20N. It was confirmed that the adhesive had sufficient peel resistance. In contrast, in the support type gloves according to Comparative Examples 3 to 8, the peel strength value was 20 N or less, and it was confirmed that the peel resistance was not necessarily sufficient. In addition, the support type gloves according to Comparative Examples 1 and 2 had peel strength values ​​exceeding 20N. Although the second polymer coating had sufficient peeling resistance, it was found that the second polymer coating was exposed from the inner surface. was recognized. Furthermore, in the support type gloves according to each example, the tear strength value was over 20N. It was confirmed that the material had sufficient tear resistance.

[0084] In addition, the IR spectra of the inner surfaces of the support gloves according to Examples 2 and 5 show that the comparative The IR spectrum of the NBR coating as-is contained specific absorptions. Similarly, the IR of the inner surface of the support type gloves according to Examples 7, 8, and 10 The spectra include those of a comparative NR coating, an acrylic polymer coating, and The IR spectrum of the PU coating contained specific absorptions. On the other hand, the IR spectrum of the inner surface of the support type glove according to Comparative Example 3 shows that the NBR coating, The specific characteristics observed in the IR spectra of the NR coating, acrylic polymer coating, and PU coating Absorption was not included. From these results, in the support type gloves according to Examples 2, 5, 7, 8, and 10, It was confirmed that a first polymer coating was formed on the inner surface.

[0085] Furthermore, the dynamic friction coefficient values ​​of the support type gloves according to Examples 1 to 7, 10, and 11 are: The coefficient of dynamic friction is higher than that of the support type glove according to Comparative Example 3, and The coefficient of dynamic friction of the support type glove according to Comparative Example 3 is 27. The value was lower than the coefficient of dynamic friction. In addition, the coefficient of dynamic friction of the support type gloves according to Examples 12, 13, and 16 to 18 was The coefficient of dynamic friction is higher than that of the support type glove according to Comparative Example 7, and The coefficient of dynamic friction of the support type gloves according to Comparative Example 7 and 15 is The coefficient of friction was lower than the value. Furthermore, the coefficient of dynamic friction of the support type gloves according to Examples 19 to 21 and 24 to 26 is higher than the coefficient of dynamic friction of the support type glove of Comparative Example 8, and The coefficient of dynamic friction of the support type gloves according to Comparative Example 8 and 23 is The coefficient of friction was lower than the value. From this, it was decided that the first polymer coating would be one of the NBR coating, NR coating, and PU coating. In either case, the grip strength of the inner surface of the support glove is improved and slippage of the inner surface is reduced. It was found that this improved workability, and the first polymer coating was changed to an acrylic polymer. It can be seen that the coating improves the ease of putting on and taking off support gloves.

[0086] In addition, the support type gloves according to each example all rated "no discomfort" on the inner surface. This makes it possible to reduce discomfort when wearing the product. [Explanation of symbols]
