[0010] [Figure 1] This is a close-up photograph of the surface of the oil-coated fabric. DETAILED DESCRIPTION OF THE INVENTION

[0011] (oil-coated fabric) The oil-coated fabric of this embodiment has a fabric body, an oil-coating layer formed on the fabric body, and air bubbles or bubble burst marks formed in the oil-coating layer. More specifically, as shown in Figure 1, the oil-coated fabric has a woven fabric body, an oil-coating layer formed on the surface of the fabric body, and air bubbles and bubble burst marks formed in the oil-coating layer.

[0012] (Fabric body) The main fabric is, for example, a woven or knitted fabric made of synthetic fibers. More specifically, the main fabric is a nylon fabric woven from nylon yarn containing 50% or more by weight of recycled nylon. The nylon yarn is, for example, a taslan-processed yarn.

[0013] (oil coating layer) The oil coating layer contains, for example, paraffin, a non-fluorine-based water repellent, a urethane resin, and a foaming agent. The paraffin is, for example, solid paraffin, 70% of which is plant-derived paraffin such as carnauba wax or rice wax. The water repellent agent is, for example, a CO water repellent agent containing 50% or more of plant-derived components. The urethane resin is, for example, a urethane resin containing 50% or more of plant-derived components. The foaming agent is, for example, microcapsules of acrylonitrile resin.

[0014] (bubbles and burst marks) The bubbles and burst marks formed in the oil coating layer are the result of foaming of the foaming agent and the marks caused by the bursting of the foamed bubbles. These bubbles and burst marks give the surface of the oil-coated fabric a texture similar to that of an oil-coated cotton fabric. In particular, even if the fabric itself is a thin synthetic fiber fabric, the flimsy feel is reduced, resulting in a texture similar to that of an oil-coated cotton fabric. Furthermore, the bubbles and burst marks formed in the oil coating layer reproduce the chalk marks unique to oil-coated fabrics. These chalk marks can be removed by heating with an iron or the like.

[0015] [Oil coating method] Next, the oil coating method will be described. (Kneading process) 0.1 to 0.5 parts by weight of foaming agent and 5 parts by weight of water are mixed to form an emulsion, and then 13 to 18 parts by weight of solid paraffin, a CO water repellent, a penetrating agent, a crosslinking agent for fabric adhesion, 17 to 20 parts by weight of urethane resin, a thickener, 10 parts by weight of water, a neutralizing agent, a crosslinking agent for the urethane resin, and a thickener are added in that order and kneaded to form a paste. (Coating process) The paste-like mixture is applied thinly and uniformly to the surface of the nylon material. (drying process) The nylon fabric coated with the mixture is dried at 120℃ to 160℃. This completes the oil coating of the nylon fabric.

[0016] [Example] To an emulsion of 0.5 parts by weight of a foaming agent (Microsphere FN-100SSD) manufactured by Matsumoto Yushi Pharmaceutical and 5 parts by weight of water, 40 parts by weight of a paraffin agent (Palladium SS) manufactured by Ohara Palladium Chemical, 75 parts by weight of a CO water repellent (Mayshield Z-5) manufactured by Meisei Chemical, 1 part by weight of a penetrating agent (Minex WOR) manufactured by Meisei Chemical, 10 parts by weight of a crosslinking agent (SU-268A) manufactured by Meisei Chemical, 80 parts by weight of a urethane silicone agent (PNA-165) manufactured by Ohara Palladium Chemical, 10 parts by weight of a thickener (Neo Sticker V) manufactured by Nicca Chemical, 10 parts by weight of water, 3 parts by weight of 28% ammonia water, 10 parts by weight of a crosslinking agent (NK Assist Ci02) manufactured by Nicca Chemical, and 5 parts by weight of a thickener (Neo Sticker S) manufactured by Nicca Chemical were added in this order and kneaded to obtain a paste-like mixture (coating agent). This coating agent was applied to a fabric body woven from high-density nylon taslan-processed yarn, and the applied coating agent was dried at 120°C and then heated at 150°C for 1 minute. An enlarged photograph of the coated fabric obtained is shown in Figure 1. As shown in Figure 1, bubbles have formed on the surface.

[0017] As described above, the oil-coated fabric of this embodiment closely resembles a cotton fabric coated with oil, even if the fabric itself is a synthetic fiber fabric such as nylon.

[0018] In the above embodiment, a form in which a kneaded material (coating agent) is applied to the surface of the fabric body has been described, but this is not limited to this. For example, a coating agent may be applied to a thread, dried, and then the coated thread may be woven.
