Description

  The present invention relates to a pile knitted fabric in which a pile is formed on one side, and more particularly to a pile knitted fabric in which a peculiar pattern of tone is revealed on the surface on the pile side.

  Conventionally, as a pile knitted fabric used for bedding and other items such as towels, skin comforters, sheets, etc., so-called single-sided piles in which pile yarn is knitted into a base material portion that becomes a base fabric by warp knitting and a pile is formed on one side thereof Knitted fabric is known.

  In such a pile knitted fabric, as disclosed in Patent Document 1 below, as a method for causing a pattern pattern to appear on the surface on the pile side, the tip of the pile protrudes on the back side of the base fabric (base material) by warp knitting. After knitting in such a manner, the surface side of this base fabric is printed, and then the pile is pulled to the surface side of the base fabric and raised to raise the pile, while the base portion is printed and the tip portion is not printed. Compared to the case where the pattern is printed directly on the pile surface, the pattern pattern has a clear outline, and the pattern tip with a blurring effect is expressed by the pile tip that is not printed. A pile knitted fabric is proposed.

  However, in the case of this proposal, a pile length of a certain degree or more is required in the production thereof, and a short pile or a loop pile cannot obtain a beautiful blur effect, and even a pile length that can obtain a blur effect, Depending on the pile's hair cracking or falling state, the color tone may become partially shaded and become patchy, and it does not become a deep and beautiful pattern.

  In addition, as described in Patent Document 2 below, by controlling the penetration of the dyeing liquid, the decoloring liquid, etc. by utilizing the centrifugal force due to rotation, at least a part of the napped hair is colored or decolored, and the distance to the base fabric There has also been proposed a pile knitted fabric in which the color is changed along the surface where the color changes.

In this case, the dyeing process in the manufacture is troublesome and time-consuming, and the cost is high, and the depth of appearance is still lacking.
Japanese Patent Publication No. 3-46576 Japanese Patent Publication No. 61-36108

  The present invention has been made in view of the above, and makes it possible to easily develop a pile knitted fabric that exhibits a beautiful and elegant appearance by displaying a pattern having a uniform and beautiful tone on the surface of the pile side. It is intended to be provided at a low cost.

The present invention that solves the above problems is a pile knitted fabric in which a pile of pile yarns different from the main constituent yarn of the base fabric is formed on one side of a base fabric whose main constituent yarn is a polyester fiber yarn. When the fabric basis weight is 200 g / m ² or less, the back side opposite to the pile side of the base fabric is dyed by a transfer printing method using a heat transfer dye, It is characterized in that it is made to appear as a pattern having a gradation on the surface of the pile side through the cloth and the pile.

According to this pile knitted fabric, the fabric basis weight is 200 g / m ² or less, the thickness and density of the base fabric itself and the pile density are moderately suppressed, and the dyed pattern by the transfer printing method on the back surface is the above-mentioned Through the base fabric and the pile, it appears lightly and lightly on the pile side surface. Therefore, the tone-like pattern on the surface on the pile side exhibits a deep and elegant appearance.

  Moreover, since the dyeing of the back side opposite to the pile side is particularly by the transfer printing method using a heat transferable dye, the dye hardly penetrates into the pile side of the base fabric, and the pile yarn is not There is no dyeing. Therefore, the dyed pattern on the back side of the base fabric appears lightly and grayishly on the surface of the pile side through the base fabric and the pile, and even if the pile is split or fallen, The pattern of the gradation pattern is not disturbed or shaded, and the pattern does not become patchy. The pattern pattern exhibits a uniform and beautiful gradation as a whole in any use state.

When the fabric basis weight is larger than 200 g / m ² , the thickness of the base fabric increases, or the density of the base fabric itself and the pile density increase, and the dyed pattern by the transfer printing on the back surface appears on the pile side surface. It becomes difficult to put out, and the effect of making the pattern appear light and tones cannot be obtained. The fabric basis weight may be 200 g / m ² or less. However, the smaller the fabric basis weight, the lower the shape retention strength as a pile knitted fabric and the lack of practicality. The basis weight is preferably in the range of 70 g / m ² or more and 200 g / m ² or less.

  In the pile knitted fabric, the pile length is preferably 2 to 6 mm. In other words, the longer the pile length, the more difficult it is to see the dyed pattern on the back of the base fabric, and the effect of making the dyed pattern appear as a light-tone pattern is not obtained. If the pile length is too short, the effect of forming the pile cannot be obtained.

In particular, the fabric basis weight is 120 to 160 g / m ² and the pile length is 2 from the viewpoint of the effect of making the dyed pattern on the back side by the transfer printing appear lightly on the pile side surface and the practicality as a pile knitted fabric. It is preferable that it is ˜4 mm.

  The pile knitted fabric may be of any knitting form, but in practice, a knitting yarn as a main constituent yarn that continuously forms stitches in the knitting direction by warp knitting, and the knitting yarn A pile knitted fabric in which the base fabric is knitted by an insertion yarn that is inserted sideways with respect to the base fabric, and pile yarn is knitted on the base fabric to form a pile on one side, Is a polyester fiber yarn, and the laterally inserted yarn is a yarn selected from polyester, nylon, and cotton, or a blend of two or more of these yarns, and the pile. For the yarn, a fiber yarn not dyed with a heat transfer dye is used. As the pile yarn, a cotton or cellulosic fiber yarn having a good feel and feel is more preferably used. Thereby, dyeing | staining by transfer textile printing can be given with respect to a base fabric back surface.

  The transfer printing method uses a heat transfer dye to print (apply) images such as letters and designs on various transfer sheets such as coated paper and kraft paper, and this printed transfer sheet The printed image is transferred to the back surface of the base fabric of the pile knitted fabric, which is the fabric to be dyed, by heat pressure, that is, by applying the required heat (about 200 ° C.) and pressing it.

  The heat transferable dye used for dyeing by this transfer printing method is a dye having a good sublimation property among disperse dyes, and is particularly dyed on the knitting yarn of the polyester fiber which is the main constituent yarn of the base fabric. However, it consists of a dye that does not dye the pile yarn, particularly cotton or cellulosic fibers.

  As described above, according to the pile knitted fabric of the present invention, the dyed pattern by the transfer printing method applied to the back side of the base fabric which is a non-pile side is a pattern in which the tone on the side of the pile is lightly shaded through the base fabric or the pile. Even if it appears as a pattern, and it is pressed by hand, and the splitting or falling of the pile occurs, the tone pattern does not become shaded and becomes patchy, and the overall tone is uniform. In addition, even when the pile length is relatively short or a loop pile, a uniform tone pattern can be expressed as a whole. Therefore, it is possible to exhibit an elegant design effect rich in elegance that has never existed before. In addition, since it can be dyed by the transfer textile printing method, the labor required for the dyeing process can be reduced, and it can be obtained easily and at a low cost.

  Next, embodiments of the present invention will be described based on examples shown in the drawings.

  FIG. 1 is a perspective view of a pile knitted fabric according to the present invention, FIG. 2 is an enlarged schematic sectional view of the same part, and FIGS. 3 to 5 are explanatory diagrams of dyeing processing by a transfer printing method of a pile knitted fabric It is.

  In the figure, A represents a pile knitted fabric according to the present invention, and a single side 1a of a base fabric 1 whose main constituent yarn is a polyester fiber yarn is formed of a pile yarn 3 different from the main constituent yarn of the base fabric 1. It consists of what is called a single-sided pile knitted fabric in which the pile 3a was formed. 1b in the figure shows the back surface of the base fabric 1. This pile knitted fabric A is preferably warp knitted by a Raschel knitting machine or a pile warp knitting machine, and a knitting yarn Y1 as a main constituent yarn that is continuously formed in the knitting direction, for example, chain knit. The base fabric 1 is knitted by the laterally inserted yarn Y2 that is laterally inserted across a plurality of stitch rows with respect to the knitting yarn Y1, and the knitting yarn Y1 of the base fabric 1 has the knitting yarn Y1. A pile yarn 3 is knitted to form a pile 3a on the one side 1a.

  The knitting structure of the base fabric 1 may be any knitting structure as long as the pile 3 a can be formed on one side 1 a of the base fabric 1. Further, as a method of forming the pile 3a by warp knitting, in addition to the case where the pile 3a is formed on the one side 1a at the same time as the knitting, the pile 3a is knitted so that the front end portion protrudes toward the back surface 1b. The pile 3a may be drawn out to the one side 1a by a brushing roll. These piles 3a may be used in the form of loop piles as shown in the figure, or may be cut piles obtained by cutting loops, or piles that are further raised and trimmed. Further, by using a double raschel machine having two rows of front and rear knitting needles, both the front and rear base fabrics are knitted by the front and rear knitting needle rows, and the front and rear base fabrics are knitted so as to be connected by pile yarns. A cut pile knitted fabric obtained by cutting the pile yarn in the middle between base fabrics may be used.

In any case, the pile knitted fabric A in the present invention has a fabric basis weight of 200 g / m ² or less, preferably 70 g / m ² or more and 200 g / m ² or less. The back side 1b opposite to the pile side is dyed with a predetermined pattern by a transfer printing method using a heat transferable dye, and the dyed pattern 5 penetrates the base fabric 1 and the pile 3a and the pile side surface It is shown as a pattern with a tone of 6.

  In the knitting of the pile knitted fabric A, in order to make the fabric weight within the above range, each knitting yarn, that is, the knitting yarn Y1, which is the main constitutive yarn of the base fabric 1, the laterally inserted yarn Y2, and the pile yarn It is desirable to knit the Y3 thread use as follows.

  For the knitting yarn Y1 as the main constituent yarn, a multifilament yarn of polyester fiber of, for example, 75d to 300d (denier), more preferably 100d to 300d is mainly used.

  As the horizontal insertion yarn Y2, 75d to 300d (denier), more preferably 100d to 300d polyester or nylon fiber multifilament yarn, or any one yarn selected from polyester, nylon and cotton, or these In the case of a single yarn, 10 to 40 yarns (cotton yarn) are used, and in the case of twin yarns, 20 to 80 yarns are used.

  The pile yarn 3 is a fiber yarn that is not dyed to a heat transfer dye for dyeing the base fabric 1 by transfer printing. For example, a cotton yarn or a cellulosic fiber yarn is preferably used. Is done. The pile yarn is preferably 10 to 40 (cotton) yarn in the case of a single yarn, and 20 to 80 yarn in the case of a twin yarn. More preferably, it is a single yarn of cotton or cellulosic fibers, and 16 to 30 yarns are used. In addition, the pile length of the pile 3a using this pile yarn is preferably in the range of 2 to 6 mm. More preferably, the pile length is 2 to 4 mm.

  A manufacturing method for obtaining the pile knitted fabric A as described above will be described.

The knitting of the pile knitted fabric A is knitted in the same manner as before by, for example, a knitting of a pile structure by a single raschel machine or a pile warp knitting machine having point needles separately from the knitting needles. For example, the base fabric 1 is formed such that the sideways inserting yarn Y2 is inserted into the plurality of stitch rows by the knitting yarn Y1 while the stitches are continuously formed in the knitting direction by the knitting yarn Y1 as the main constituent yarn. At the same time as knitting, the pile yarn 3 is knitted, for example, with a structure that forms a pile every other course, and knitted so as to form a pile 3 a on one side 1 a of the base fabric 1. At this time, the knitting yarn Y1, the laterally inserted yarn Y2 and the pile yarn 3 of the base fabric 1 are knitted with a knitting machine gauge of 22 to 28, preferably 24 gauge, using the yarns in the above-mentioned ranges. The fabric basis weight is 200 g / m ² or less, preferably 70 g / m ² or more and 200 g / m ² or less, particularly preferably 120 to 160 g / m ² and a pile knitted fabric having a pile length of ² to 6 mm. Shall be obtained.

  Next, the pile knitted fabric A is dyed on the back surface 1b of the base fabric 1 by the transfer printing method as follows.

  At this time, the pile made of the cotton or cellulosic fiber is good for dyeing the polyester fiber used for the knitting yarn which is the main constituent yarn of the pile knitted fabric. For the yarn, as a non-dyeable heat transferable dye, a dye having good sublimation property among disperse dyes [for example, trade name: Dynics (registered trademark) manufactured by Dystar Japan Co., Ltd.] As shown in FIG. 3, a desired pattern such as a picture or a character is printed on the transfer sheet 11 by a method such as screen printing. Reference numeral 12 denotes the print portion. Then, as shown in FIG. 4, the sheet is superposed on the print portion 12 of the transfer sheet 11 so that the back surface 1b side of the base fabric 1 of the pile knitted fabric A is brought into contact, and in this state, for example, about 200 ° C. By pressing for several tens of seconds with a press device while applying heat, that is, by hot pressing, the dye of the printed portion 12 on the transfer sheet 11 is softened by heat and transferred to the base fabric 1 side, The color pattern of the dye is transferred to the back surface 1b of the base fabric 1 as it is. As a result, as shown in FIG. 5, the transferred dye is dyed on the back surface 1b without penetrating the base fabric 1 to the pile 3a side, that is, the front surface side, and a predetermined color pattern is dyed. become.

In the dyed pattern 5 on the back side thus transferred and printed, the dye itself does not penetrate to the pile 3a side, but the basis weight of the pile knitted fabric A itself is 200 g / m ² or less and the pile length is 2 to 6 mm. Since the fabric density and the pile density are suppressed, the dyed pattern 5 appears on the side of the pile 3a in a light and shaded manner through the gap of the fibers of the base fabric 1 and the pile 3a. It appears on the pile-side surface 6 through the gap and is visualized as a deep, light-tone pattern.

  For this reason, the pile knitted fabric A manufactured as described above is dyed by transfer printing on the back side as shown in FIG. 1 even though the pile surface is not printed and is colorless. No. 5 appears on the pile side surface 6 through the base fabric 1 and the pile 3a, and can express a pattern with a light and deep tone that is not found in the prior art. Moreover, even if the pile 3a is cracked or collapsed by pressing, the gradation pattern does not cause a shading or a patchy color pattern, and always has a uniform color tone. It will have an appearance.

  INDUSTRIAL APPLICABILITY The present invention can be suitably used in various fields in which bedding such as towels, skin comforters, sheets, and other conventional single-sided pile knitted fabrics are used.
