Summary of the Invention

Problems to be Solved by the Invention

[0004] However, the above prior art has a problem that when used as a beach towel, the sand adhesion rate is high and the usability is not good.

[0005] In order to solve the above conventional problems, the present invention provides a towel fabric having a low sand adhesion rate when used as a beach towel.

Means for Solving the Problems

[0006] One embodiment of the present invention relates to a towel fabric made of pile yarn, warp yarn, and weft yarn, wherein the pile yarn, warp yarn, and weft yarn are all spun cotton fibers, one side is loop pile and the other side is cut pile, the pile yarn and warp yarn are double yarns and the weft yarn is single yarn. [Effects of the Invention]

[0007] The present invention relates to a woven towel fabric composed of pile yarn, warp yarn, and weft yarn, wherein the pile yarn, warp yarn, and weft yarn are all spun cotton fibers, one side is loop pile and the other side is cut pile, the pile yarn and warp yarn are double yarns and the weft yarn is single yarn. By making this towel fabric, it is possible to create a towel fabric that is easy to use with a low rate of sand adhesion. [Brief explanation of the drawing]

[0008] [Figure 1] Figure 1 is a schematic cross-sectional view of a towel fabric according to one embodiment of the present invention. [Figure 2] Figure 2 is a schematic cross-sectional view showing the towel fabric from Figure 1 before one side is cut. [Figure 3] Figure 3 is the woven structure diagram of the towel fabric shown in Figure 2. [Figure 4] Figure 4 is a cross-sectional photograph (30x magnification) of the pile according to Example 1 of the present invention. [Modes for carrying out the invention]

[0009] Towels are generally made from 100% cotton. This is because 100% cotton towels are gentle on the skin and have good water-absorbing properties. In particular, many towels have a double-sided loop pile to prioritize water-absorbing properties. However, with double-sided loop pile, when used as a beach towel, sand tends to stick to it easily, and the sand that sticks to it is difficult to remove. The inventors investigated this problem and found that it can be solved by making one side a loop pile and the other side a cut pile, with the cut pile side facing the sand and the loop pile side facing the human body.

[0010] This invention relates to a woven towel fabric composed of pile yarn, warp yarn, and weft yarn, all of which are spun cotton fibers. This increases water absorption. One side is loop pile, and the other side is cut pile, with the pile yarn and warp yarn being double-ply yarn and the weft yarn being single-ply yarn. The cut pile side is resistant to sand, while the loop pile side has good water absorption and a pleasant feel. Furthermore, using double-ply yarn as the pile yarn results in a cross-section that is closer to a perfect circle, allowing the pile to have even resilience in all directions when cut and stand up easily. In addition, elasticity is improved, and structurally it has a stronger spring-like restorative force than single-ply yarn, increasing its recovery from being stepped on. Moreover, because the fibers are firmly trapped within the twist, there is less fiber shedding from the cut surface, suppressing fluffing. In addition, since the cut surface (sheared surface) is thinner than the pile surface, a clear print pattern can be formed when printing is applied.

[0011] The loop pile height from the surface of the towel fabric's loop pile side is preferably 4.1 to 8 mm, more preferably 4.2 to 7 mm, and even more preferably 4.3 to 6 mm. The cut pile length (cut pile height) of the cut side is preferably 2 to 4 mm, more preferably 2.2 to 3.5 mm, and even more preferably 2.4 to 3.0 mm. By shortening the pile in this way, bending from the root due to its own weight or external pressure can be prevented. For reference, the standard pile length for a typical cut pile is 4.50 mm.

[0012] The fineness of the pile yarn is preferably 1.8 to 2.5 decitex, and more preferably 1.9 to 2.3 decitex. Furthermore, the number of constituent fibers as seen from the cross-section of the pile yarn is preferably 230 to 280, and more preferably 240 to 270. The fineness of ordinary pile yarn is 1.5 to 1.7 decitex, and the number of constituent fibers is about 300, but the present invention has the advantage of using fewer thicker fine fibers, resulting in thicker and harder individual fibers, which makes the pile easier to stand upright, increases its ability to return to its original shape when stepped on (recovery), and improves its pile-standing properties.

[0013] The pile yarn is preferably twisted 18 to 26 times per inch, more preferably 20 to 24 times per inch. The twist coefficient is preferably 4.2 to 4.8, more preferably 4.4 to 4.6. The top twist count is preferably 13 to 15 times per inch, with a twist coefficient of 3.7 to 4.2. This makes it less likely for the fibers to unravel from the cut surface and maintains the ability to stand vertically. In the above, the bottom twist count is the number of twists of the single yarn, and the top twist count is the number of twists of the double yarn. For reference, the standard bottom twist count for typical pile fabric is 21 times per inch, with a twist coefficient of 4.2, and the standard top twist count is 12 times per inch, with a twist coefficient of 3.5.

[0014] The cut pile surface is preferably coated with a silicone-based softener and wax. The softener and wax are preferably applied to the cut pile surface by spray application. This suppresses lint, improves slipperiness, maintains pile uprightness, and makes it easier for sand to fall off. Using only a silicone softener would only coat the fibers, potentially causing them to become too soft and the pile to lie flat. Blending in wax provides the fibers with appropriate thickness and firmness, maintaining their independence. It is preferable to cure the coating to ensure a firm fixation.

[0015] The mass per unit area (basis weight) of the towel fabric of the present invention is 350 to 700 g / m². 2 Preferably, and more preferably, 400-670 g / m² 2 That is the case.

[0016] The towel fabric of the present invention has good wash resistance, high durability, and is easy to wipe off water. Therefore, it is suitable not only for beach towels but also for bath towels (post-bath towels), bath towels, face towels, hand towels, towel handkerchiefs (towel chiefs), towel wipes, wash towels, bath mats, sports towels, towel fabrics (body towels), etc.

[0017] The following will be described with reference to the drawings. In the following drawings, the same reference numerals denote the same components. FIG. 1 is a schematic cross-sectional view of a towel fabric 1 according to an embodiment of the present invention. This towel fabric 1 is composed of a ground weave 7, a loop pile 5 on the upper surface, and a cut pile 6 on the lower surface. When used as a beach towel, the side of the cut pile 6 on the lower surface becomes the surface that contacts the sand, and the side of the loop pile 5 on the upper surface becomes the surface that contacts the human body. This towel fabric 1 is composed of warp pile yarns 2a, 2b, weft ground yarn 3, and warp ground yarns 4a, 4b. The warp pile yarns 2a, 2b form loop piles while being locked to the ground weave composed of the weft ground yarn 3 and the warp ground yarns 4a, 4b. Then, the pile yarn on the lower surface of the towel fabric 1 is cut by gathering, and becomes a cut pile. The obtained towel fabric 1 is cut to a predetermined size and the ends are processed to become a towel.

[0018] FIG. 2 is a schematic cross-sectional view showing the state before one side of the towel fabric in FIG. 1 is cut. This towel fabric 1 is composed of warp pile yarns 2a, 2b, weft ground yarn 3, and warp ground yarns 4a, 4b. The warp pile yarns 2a, 2b form loop piles while being locked to the ground weave composed of the weft ground yarn 3 and the warp ground yarns 4a, 4b. Then, the pile yarn on the lower surface of the towel fabric 1 is cut by gathering, and becomes a cut pile. The obtained towel fabric 1 is cut to a predetermined size and the ends are processed to become a towel.

[0019] Figure 3 is a fabric structure diagram of a towel fabric according to an embodiment of the present invention. This fabric structure is a 3 - warp - width towel structure (3 - pick - terry - motion structure). The warp pile yarn is crossed once every three weft ground yarns are inserted. The warp ground yarn G and the warp pile yarn P are arranged alternately. 1 - 3 of the weft yarns indicate the order. In Figure 3, when viewed from the warp, black and × indicate floating yarns, and white indicates sunken yarns.

Example

[0020] Hereinafter, it will be described more specifically using examples. The present invention is not limited to the following examples.

[0021] The evaluation of the finished fabric was as follows. <Cross - section evaluation of the fabric> A cross - section photograph (magnification: 30 times) of the fabric was taken with an optical microscope, and the condition of the fabric surface was evaluated. The photographed fabric was in an unwashed state. <Sand adhesion rate> (1) Place the specimen on a flat tray, and using a funnel with a diameter of 1.7 cm, place 4 g of sand in the center of the specimen so that the sand (volume - average particle diameter D = 50 is 350 μm) evenly covers it. (2) Remove the funnel, lift the upper two sides of the specimen with both hands, and let the sand fall. (3) Transfer the specimen to another flat tray, and take a photograph with a camera so that no shadow falls from directly above. (4) After converting the photographed photograph to grayscale, extract the sand - adhering part by image analysis and calculate the percentage of the area.

[0022] (Example 1) (1) Warp pile yarn Warp pile yarn was produced using a Sirospun spinning machine. Combed American long staple cotton (fineness 2.0 decitex) was used. The primary twist direction of both rovings was set to the Z direction, and the spindle twisting direction was also set to the Z direction. The fineness of the rovings was 5g / 6 yards (9113 decitex), and the number of twists in the Z direction of the rovings was 5 times / inch (twist coefficient K=1 in cotton count equivalent). The resulting spun yarn (single yarn) had a cotton count of 24 and a twist count of 22 times / inch (twist coefficient K=4.5). Two of these single yarns were used to make a double yarn, with a top twist count of 14 times / inch (twist coefficient K=4.0). The number of constituent fibers as seen in cross-section of this double yarn was 250. (2) Warp yarn For the warp threads, American-grown cotton was used as the filling, and a ring-spun 24-count double yarn with a twist coefficient of 4.5 for the undertwist and 4.0 for the toptwist. (3) Weft yarn For the weft yarn, American-grown cotton was used as the filling, and a ring-spun 12-count single yarn with a twist coefficient of 4.0 was used. (4) Weaving of towel fabric The warp pile yarns and warp ground yarns were starched, and the fabric shown in Figure 2 was woven using a pile loom with the fabric structure shown in Figure 3. The warp density was 32 threads / inch, the weft density was 50 threads / inch, and the weight was 478 g / m². 2 The fabric composition is 100% cotton. The pile height of the resulting double-sided loop fabric was 4.5 mm. (5) Shirring The resulting double-sided loop fabric was sheared on one side using a shearing machine. The pile length of the cut pile side was 3 mm. (6) Scouring and finishing process for towel fabric Next, the raw fabric was descaled in a liquid jet dyeing machine according to the standard method for processing cotton (55°C for 20 minutes, in a bath with amylase and surfactant). Then, it was scouring in the same machine at 98°C for 50 minutes in a bath with dilute caustic soda and alcohol ethoxylate added. Next, it was bleached using a conventional method in a hydrogen peroxide bath at 98°C for 50 minutes, then set in a tenter at 135°C for a finishing touch (off-white finish). (7) Coating with fabric softener The fibers are coated with a silicone-based softener and paraffin wax to suppress lint, improve slipperiness, maintain pile structure, and make it easier for sand to fall off. • Fabric softener used: Riken Softener SR-505, manufactured by Miki Riken Kogyo Co., Ltd. ·Additional amount: 100g / L Paraffin wax: Hayashi Pure Chemical Industries, Ltd. ·Additional amount: 10g / L The fabric softener and wax were mixed in an emulsion. Using only silicone fabric softener would only coat the fibers, potentially making them too soft and causing the pile to lie flat. By blending in wax, the fibers were given appropriate thickness and stiffness, maintaining their independence. Furthermore, to improve wash resistance, the fabric was treated with silicone, dried, and then heat-treated (150°C). Curing helps to fix the fibers in a more stable state. A photograph of the obtained single-sided cut pile is shown in Figure 4.

[0023] (Comparative Example 1) The double-sided loop pile fabric from Example 1, before shearing, was used.

[0024] The results above are summarized in Table 1. [Table 1]

[0025] As is clear from Table 1, the single-sided sheared pile fabric of Example 1 had a low sand adhesion rate, and when used as a beach towel, the sand adhered to it was low and could be easily brushed off. [Industrial applicability]

[0026] The pile of the present invention is suitable not only for beach towels but also for bath towels (after-bath towels), bath towels, face towels, hand towels, towel handkerchiefs (towel chiefs), hand towels, washcloths, bath mats, sports towels, towel fabrics (body towels), and the like.
