Hereinafter, embodiments for carrying out the present invention will be described.

1. 1. Textile products The textile products of the present embodiment include, but are not limited to, bath towels, towels such as hand towels, washcloths, and handkerchiefs.

As shown in FIG. 1, the textile product 1 of the present embodiment has colored regions on one surface 11 and the other surface 12. One surface 11 has a first colored region 110, and the other surface 12 has a second colored region 120. In the textile product 1, the contour 111 of the first colored region 110 and the contour 121 of the second colored region 120 coincide with each other. In the present specification, the fact that the contour 111 and the contour 121 match means that the two contours 111 and 121 are completely matched and the two contours 111 and 121 are slightly different from each other. However, there are cases where it can be considered that they are almost the same. The color, shape, area, and position of the colored region are not particularly limited. However, the first colored region 110 and the second colored region 120 have the same shape, area, and position.

The fabric 10 of the textile product 1 is made of fiber. The fibers are preferably easily dyed with a reactive dye that chemically bonds with the fibers in the presence of alkali, and for example, cellulose fibers such as cotton and hemp are preferable. The dough 10 may be formed of only one type of cellulose fiber or may be formed of a plurality of types of cellulose fiber. As the fiber, for example, a cotton count of 10 to 100 count can be used. The fabric 10 is preferably a woven fabric in consideration of the strength of the textile product and the like. The structure of the woven fabric may be appropriately selected depending on the purpose of use of the textile product and the like, and is not particularly limited. For example, when the textile product is a towel, the fabric 10 is made of a pile fabric or a towel fabric. The fabric 10 may be a knitted fabric or a non-woven fabric.

When the fabric 10 is a pile fabric, the fabric 10 has a pile 13 (see FIG. 2). Specifically, the pile 13 includes a first pile 131 on the one side 11 side and a second pile 132 on the other side 12. The first pile 131 protrudes to one surface side of the ground yarn 14, and the second pile 132 projects to the other surface 12 side of the ground yarn 14. The ground yarn 14 is composed of warp yarns 141 and weft yarns 142, and the first pile 131 and the second pile 132 are composed of pile yarns 133. Therefore, the fabric 10 of the textile product 1 is composed of pile yarn 133, warp yarn 141, and weft yarn 142.

In this embodiment, the pile 13 is preferably formed from a mercerized pile yarn 133. That is, it is preferable that the first pile 131 and the second pile 132 are formed from the mercerized pile yarn 133. In this case, the pile 13 is easily colored by the color paste, and the first colored region 110 and the second colored region 120 are easily formed. Further, one of the warp and weft 142 may be mercerized, or both may be mercerized. That is, the ground thread 14 may be formed from a mercerized thread. In this case, the ground yarn 14 is easily colored by the color paste.

In the present embodiment, it is preferable that the first colored region 110 and the second colored region 120 are colored with the same color paste. This color paste contains a reactive dye. The color glue may contain water, a glue, or the like, if necessary.

Reactive dyes color the dough by chemical bonding with the OH groups of the cellulose of the dough. Coloring with a reactive dye is preferably a one-phase method to which a wide range of dyes can be applied. As this one-phase method, for example, a substitution reaction type coloring method using a monochrome rotriazine dye, an addition reaction type coloring method using a vinyl sulfone dye, or both a functional group of a monochrome rotriazine dye and a functional group of a vinyl sulfone dye. There is a coloring method using a dye provided with.

In the textile product 1 of the present embodiment, the weight of the dough 10 is preferably 180 g / m ² , and the length (pile length) of the pile 13 of the dough 10 is preferably 20 mm or more. The pile length means the protruding length from the ground yarn 14 to the top of the pile 13. The textile product 1 of the present embodiment is colored by the first colored region 110 on one surface 11 and the second colored region 120 on the other surface 12, even if the fabric 10 is thick and has a weight and pile length in the above ranges. At the same time, the contour 111 of the first colored region 110 and the contour 121 of the second colored region 120 can be matched.

2. 2. About the manufacturing method of the textile product In the present embodiment, the textile product 1 is manufactured as follows.

First, fibers for forming the dough 10 are prepared. Examples of the fiber include cellulose fibers such as cotton and hemp. From these fibers, pile yarn 133, warp yarn 141, and weft yarn 142 are formed. In the present embodiment, it is preferable to mercerize at least the pile yarn 133 among the pile yarn 133, the warp yarn 141, and the weft yarn 142. When the pile yarn 133 is mercerized, for example, the pile yarn 133 is treated with a high-concentration caustic soda solution while the pile yarn 133 is under tension. After the treatment, it is preferable to neutralize with sulfuric acid or the like and then reverse neutralize with ammonia. In the mercerizing process of the pile yarn 133, it is preferable to apply tension in a state where the fibers constituting the pile yarn 133 are swollen. As a result, the cross-sectional shape of the fiber changes to an elliptical shape, and the gloss of the pile yarn 133 is improved. Further, by applying tension to the fiber, the shape of the fiber is stabilized, the amorphous region of the fiber is increased, the pile yarn 133 is easily colored by the dye, and the dyed pile yarn 133 is darkened. Can be done. Further, in the mercerizing of the pile yarn 133, a high-concentration alkali treatment may be performed instead of applying tension. In addition to the pile yarn 133, the warp 141 or the weft 142 may be mercerized, or the warp 141 and the weft 142 may be mercerized. In this case, it is easy to color the ground yarn 14 including the warp and weft 142.

Next, a warping step is performed. In this step, a warp machine is used to arrange the required number, length, and tension of the warp 141.

Next, the weaving process is performed. In this step, the fabric 10 is produced by weaving the warp 141, the weft 142, and the pile yarn 133.

Next, the edge sewing process is performed. In this step, the edge sewing of the fabric 10 is performed by an oversewing machine or the like.

Next, a refining / gluing step is performed. The treatment bath used in this step contains, for example, caustic soda at a concentration of 1.5 g / L and hydrogen peroxide at a concentration of 8 g / L. The bath ratio of the treatment bath is, for example, 1:13. The treatment conditions are, for example, a temperature of 90 ° C. or higher and 95 ° C. or lower, and a time of about 90 minutes.

Next, a chlorine bleaching step is performed. The treatment bath used in this step contains, for example, sodium hypochlorite at a concentration of 12 g / L. The bath ratio of the treatment bath is, for example, 1:13. The treatment conditions are, for example, a temperature at room temperature and a time of 60 minutes.

Next, a washing / softening process is performed. In this step, for example, continuous wins are used. The treatment conditions are, for example, a temperature of about 70 ° C. and a time of 20 to 30 minutes.

Next, a dehydration step is performed. In this step, the dough 10 is dehydrated using a centrifugal dehydrator or the like.

Next, a drying step is performed. In this step, the dough 10 is dried using a continuous dryer or the like. The treatment conditions are, for example, a temperature of 100 to 120 ° C. and a time of 10 minutes.

Next, a cutting step is performed. In this step, the long dough 10 is cut to a predetermined length. As a result, the dough 10 having a predetermined area is obtained. Further, in the cutting step, it is preferable to confirm the state and quality of the cut dough 10 (intermediate inspection).

Next, the printing process is performed. In this step, the color paste is printed on the fabric 10. Printing on the fabric 10 is performed, for example, by the screen printing machine 20. The screen printing machine 20 prints by a mimeograph method.

The screen printing machine 20 shown in FIG. 3 has a conveyor belt 21 which is a printing table. Above the conveyor belt 21, a plurality of print molds 22 are provided along the traveling direction of the conveyor belt 21. The plurality of print molds 22 include a first print mold 221, a second print mold 222, and a third print mold 223. The print mold 22 is formed by attaching a screen (gauze) 24 to a frame-shaped frame 23. Further, the screen 24 is provided with a mesh portion 25. The mesh portion 25 is formed in a desired shape. A squeegee 26 made of rubber or the like is arranged above the print mold 22. The squeegee 26 is formed so as to be able to reciprocate in a direction orthogonal to the traveling direction of the conveyor belt 21.

The printing process of the present embodiment includes the first step to the fifth step. These first to fifth steps will be described with reference to FIGS. 4A to 4D.

First, in the first step, a color paste containing a dye is printed on a predetermined area on the printing table. Specifically, as shown in FIG. 4A, the color paste 30 containing the reactive dye is printed on the conveyor belt 21 using the first print type 221. The color glue 30 is alkaline. The screen 24 of the first print type 221 has a mesh portion 25 having the same shape as the second colored region 120. By moving the squeegee 26 after supplying the color glue 30 onto the screen 24 of the first print type 221, a part of the color glue 30 can pass through the mesh portion 25. The color glue 30 that has passed through the mesh portion 25 is supplied onto the conveyor belt 21 in the same shape as the mesh portion 25.

Next, in the second step, the fabric is placed on the printing table so that the predetermined area is covered and the color paste and one side 11 of the fabric 10 overlap. Specifically, as shown in FIG. 4B, the dough 10 is arranged on the conveyor belt 21 so that the color glue 30 on the conveyor belt 21 and one side 11 of the dough 10 overlap. As a result, the color glue 30 is adsorbed on one surface 11. The region where the color paste 30 is adsorbed on the one surface 11 is the first colored region 110 described above. In the present embodiment, since the pile 13 is formed of the mercerized pile yarn 133, the second pile 132 located on the one side 11 side can be easily colored with the color paste 30. Further, it is possible to prevent the color paste 30 from adhering to the region other than the first colored region 110 on the front surface 11 (white field contamination). Further, since the fabric 10 is arranged on the color glue 30 arranged on the conveyor belt 21, it is easy to color not only the surface of the pile 13 but also the inside of the pile 13. Further, when at least one of the warp and weft 142 constituting the ground yarn 14 is mercerized, the ground yarn 14 is easily colored by the color paste 30 arranged on the conveyor belt 21.

Next, in the third step, the exudation suppressing glue 31 is arranged along the contour of the region corresponding to the predetermined region on the other surface 12 of the fabric 10. Specifically, as shown in FIG. 4C, the second print mold 222 is used to print the exudation inhibitor glue 31 on the other surface 12 of the fabric 10 along the contour 111 of the first colored region 110. Since the screen 24 of the second print type 222 has a mesh portion 25 along the contour 111, the squeegee 26 is moved after supplying the exudation suppressing glue 31 onto the screen 24 of the second print type 222 to cause stains. A part of the ejection suppressing glue 31 can pass through the mesh portion 25. The exudation suppressing glue 31 that has passed through the mesh portion 25 is printed on the other surface 12 with the same shape as the mesh portion 25. As a result, the exudation suppressing glue 31 is arranged on the other surface 12 along the contour 121. In the third step, it is preferable to apply tension to the dough 10 so that the exudation suppressing glue 31 does not shift. When tension is applied to the dough 10, it is preferable to prevent wrinkles from forming on the dough 10.

The exudation inhibitor glue 31 contains a resist dye. The exudation suppressing glue 31 may contain table glue, water, or the like. By containing the resist dyeing agent in the exudation suppressing glue 31, the exuding suppressing glue 31 can be made acidic. The resist dyeing agent is not particularly limited as long as it can acidify the exuding inhibitor glue, and is, for example, citric acid. The ratio of the resist dyeing agent to the total weight of the exudation-suppressing glue 31 is preferably 1% or more and 5% or less, and more preferably 1.5% or more and 2.5% or less. The exudation suppressing glue 31 preferably contains a base glue. The viscosity of the exudation suppressing glue 31 can be improved by the base glue. By improving the viscosity of the exudation suppressing glue, it is easy to maintain the shape of the exuding suppressing glue 31. The base glue is not particularly limited as long as it can improve the viscosity of the exudation suppressing glue 31, but for example, "Viscon S 500HN" manufactured by Shin-Nakamura Kogyo Co., Ltd. can be used. The ratio of the base glue to the total weight of the exudation suppressing glue 31 is preferably 2% or more and 10% or less, and more preferably 3% or more and 7% or less. Within this range, it is particularly easy to maintain the shape of the exudation suppressing glue 31. In order to facilitate the application of the exudation suppressing glue 31, it is preferable that the exuding suppressing glue 31 contains water. The ratio of water to the total weight of the exudation-suppressing glue 31 is preferably 85% or more and 97% or less, and preferably 90% or more and 95% or less.

Next, in the fourth step, the color glue 32 is printed on the inside of the area surrounded by the exudation suppressing glue 31. Specifically, as shown in FIG. 4D, the color glue 32 is printed on the inside of the region surrounded by the exudation suppressing glue 31 on the other surface 12 by using the third print type 223. In this embodiment, the color glue 32 has the same composition as the color glue 30. The color glue 32 is not limited to this, and the color glue 32 may have a composition different from that of the color glue 30. The screen 24 of the third print type 223 has a mesh portion 25 having the same shape as the second colored region 120. By moving the squeegee 26 after supplying the color glue 32 onto the screen 24 of the third print type 223, a part of the color glue 32 can pass through the mesh portion 25. The color glue 32 printed on the other surface 12 is adsorbed on the other surface 12. The region on the other surface 12 to which the color paste 32 is adsorbed becomes the second colored region 120. Since the color paste 32 containing the reactive dye is alkaline and the exudation inhibitor glue 31 containing the resist dye is acidic, the alkaline color paste 32 is neutralized by the exudation inhibitor glue 31. Since the reactive dye contained in the color glue 32 chemically bonds with the dough 10 in the presence of an alkali, the color glue 32 is neutralized, so that the color of the dough 10 by the color glue 32 is suppressed. Since the position of the mesh portion 25 is the same as the region surrounded by the first coloring region 110 and the exudation suppressing glue 31, the color paste 32 exudes to the outside of the region surrounded by the exuding suppressing glue 31. Hateful. Therefore, the contour 111 of the first colored region 110 formed of the color glue 30 and the contour 121 of the second colored region 120 formed of the color glue 32 can be matched with each other. Further, in the fourth step, it is preferable to apply tension to the fabric 10 so that the printing of the color paste 32 does not shift. Further, in the present embodiment, since the pile 13 is formed of the mercerized pile yarn 133, the second pile 132 located on the other surface 12 side can be easily colored with the color paste 32. Further, it is possible to prevent the color paste 32 from adhering to the region other than the second colored region 120 of the other surface 12 (white field contamination). Further, since the pile 13 on the one side 11 side of the fabric 10 is colored in the second step and then the pile 13 on the other side 12 side is colored in the fourth step, not only the surface of the pile 13 but also the inside of the pile 13 is colored. Easy to color. Therefore, it is possible to prevent the surface of the pile 13 from being colored as if it is faint by printing only on the surface of the pile 13. Further, when at least one of the warp and weft 142 constituting the ground yarn 14 is mercerized, the ground yarn 14 can be easily colored by the color paste 32.

Further, it is also preferable that the color paste 32 is supplied to the other surface 12 using the third print mold 223 in the fourth step more than once. That is, it is preferable to perform the step of moving the squeegee 26 twice or more after supplying the color paste 32 on the screen 24 of the third print type 223. In this case, not only the color glue 32 can be adsorbed on the other surface 12, but also the color glue 32 can be impregnated up to the one surface 11. This makes it possible to suppress color unevenness and color loss in the first colored region 110 and the second colored region 120.

Next, a drying step is performed. In this step, the fabric 10 after the printing step is dried. As the treatment conditions in the drying step, for example, the temperature is preferably 110 to 120 ° C., and the time is preferably about 10 minutes in order to improve the desalination property in the washing / softening step described later by preventing overdrying.

Next, the sewing machine process is performed. In this step, by sewing the dough 10 with a sewing machine, the portions of the dough 10 cut in the above-mentioned cutting step can be connected.

Next, a steaming process is performed. In this step, the dough 10 is heated by saturated steam or heated steam using a continuous steamer. By the steaming step, the OH group of the cellulose constituting the dough 10 and the reactive dye in the colored pastes 30 and 32 are chemically bonded to color the first colored region 110 and the second colored region 120. The treatment conditions in the steaming step are, for example, a temperature of 100 to 130 ° C. and a time of about 10 minutes.

Next, a washing / softening process is performed. In this step, for example, continuous wins are used, and the dough 10 is washed with hot water and water. As a result, the exudation-suppressing glue 31 adhering to the other surface 12 of the fabric 10, the base glue (for example, sodium alginate) contained in the color glues 30 and 32, the unreacted reactive dye, and the like can be removed. In the washing / softening process, hot water washing is performed, for example, twice. The treatment conditions for the first washing with hot water are a temperature of 60 ° C. and a time of 10 minutes. The treatment conditions for the second washing with hot water are a temperature of 90 ° C. and a time of 10 minutes. It is also preferable to wash with water after washing with hot water. Further, it is preferable to wash with water three times or more. It is also preferable that the treatment bath in washing with water contains 1 g / L of a softener, if necessary. As the softener, for example, the trade name "Royal Soft" manufactured by Yushi Kogyo Co., Ltd. can be used.

Next, a drying step is performed. In this step, a tumbler dryer or the like is used to dry the dough 10. The treatment conditions in the drying step are, for example, a temperature of 80 to 100 ° C. and a time of 30 minutes. After that, textile products such as towels are manufactured through a hem sewing process and an inspection process.
