(Industrial Field of Application) The present invention relates to a method for manufacturing a napped product having a napped portion consisting of long, thick prickly hair and short, thin fluff. (Prior Art) Conventionally, as a method for obtaining a napped product having prickly hair and fluff, as disclosed in Japanese Patent Publication No. 59-45788, a napped fiber structure is attached to a rotating cylinder and rotated. There is a method of forming fluff and tapering the tip of the stinging bristles by bringing the tip into contact with a solvent solution, etc., and a method of forming fluff and tapering the tip of the bristles, as disclosed in Japanese Patent Application Laid-Open No. 55-57069.
There is a method of applying a viscosity treatment agent containing a solvent to the raised surface of a fabric having a raised portion made of more than one type of synthetic fiber. (Problems to be Solved by the Invention) However, the former conventional technique requires a device having a complicated mechanism to form the raised portion.
In addition, in the latter prior art, the stinging hair is affected by the use of a treatment agent used to form fluff,
There were problems such as fineness and deterioration of the surface condition. The present invention is intended to solve these problems, and aims to produce high-quality napped products using a conventional textile printing machine without requiring any special equipment. (Means for Solving the Problems) The present invention provides for a surface of a synthetic fiber napped fabric having a napped portion made of a mixture of two or more synthetic fibers having different dissolution rates in a solvent. This is a method for producing a raised product, characterized in that a dissolution treatment solution is applied in the order of a low viscosity liquid and a high viscosity liquid, followed by heat treatment. The napped fiber structure applied to the present invention is one in which two or more types of synthetic fibers having different dissolution rates in a solvent are dispersed on the surface of the fiber structure to form napped fibers. Here, synthetic fibers with different dissolution rates in solvents are a combination of synthetic fibers with different constituent polymers, single fiber fineness, surface/cross-sectional shape, etc., and when the fibers are treated with a solvent, the dissolution rates differ. This allows only specific synthetic fibers to be selectively removed. For example, combinations of different polymers include polyethylene terephthalate and polybutylene terephthalate, cationic dyeable polyethylene terephthalate and polybutylene terephthalate, etc., and the single yarn fineness is 15 to 60D for fibers that will become prickly hair, and 15 to 60D for fibers that will become fluff. is 0.2~8D,
It is preferable that the ratio of both fibers is about 25 to 40.
Further, it is preferable that the cross-sectional shape of the fibers forming the bristles is atypical cross-sectional shapes such as flat, triangular, or spindle-shaped because the dissolution rate is further increased. The napped fiber structure of the present invention may be a woven fabric, a knitted fabric, or a nonwoven fabric as long as it has napped portions as described above, and the napped length, constituent polymer, etc. are not particularly limited, but the napped length is 5 to 80 mm, napped Density is 3000 ~
Approximately 20,000 lines/cm 2 is preferable. The dissolution treatment solution of the present invention is one that dissolves or hydrolyzes the synthetic fibers, and the solubilizing agent depends on the fiber used, so it is not particularly limited, but when polyamide fibers are used, sulfuric acid, hydrochloric acid, formic acid, phenol, metacresol, etc. , dimethyl sulfoxide, etc. When polyester fibers are used, chlorophenol, sodium hydroxide, potassium hydroxide, etc., with sodium hydroxide being particularly preferred, and when acrylonitrile fibers are used, dimethylformamide, dimethyl sulfoxide, ethylene carbonate, etc. Examples include sulfuric acid. In the case of polyester fibers, such a dissolving agent is an alkaline aqueous solution with a pH of about 14, which is adjusted by adding a sizing agent such as sodium alginate, sodium polyacrylate, polyvinyl alcohol, or starch. Use as a dissolution treatment solution. Such dissolving treatment solution is a low viscosity liquid.
The viscosity is preferably from 1,500 to 4,000 centipoise; if it is less than 1,500 centipoise, the fluidity of the dissolution treatment solution is high, and the entire napped fiber is uniformly exposed to the solution, making it impossible to selectively treat specific areas. Moreover, if it exceeds 4000 centipoise, it becomes difficult to penetrate the dissolution treatment solution to the roots of the napped fibers. On the other hand, high viscosity liquid is 3000~15000
The viscosity is preferably centipoise, 3000
If the centipoise is less than 15,000 centipoise, the solution will penetrate to the base of the napped fibers, and if it exceeds 15,000 centipoise, it will be difficult to handle using a normal printing machine, and it will be difficult to apply the solution evenly to the napped surface. Next, the viscous dissolution treatment liquid is applied to the surface of the napped fiber structure. The application method is not particularly limited, and examples thereof include various coating methods such as a knife coating method and a gravure coating method, and printing methods such as a flat screen method and a rotary screen method. In the present invention, the viscous dissolution treatment liquid with the two concentrations is
First, a low viscosity liquid is applied, and then a high viscosity liquid is applied in a wet state. The low viscosity liquid mainly dissolves and removes the tips of the synthetic fibers on the side where the dissolution rate is faster, forming fluff, and the fluff is formed by dissolving and removing the ends of the synthetic fibers, which have a faster dissolution rate.
Visually effective fluff can be obtained by penetrating to about 15 mm. On the other hand, the high viscosity liquid is used to dissolve and taper the tips of the bristles, and is preferably allowed to penetrate approximately 3 to 5 mm from the tips of the standing bristles. In order to apply a dissolution treatment solution in such a range, it is generally necessary to use a low viscosity liquid at 1,800 to 2,100 g/m 2 (300 g/m2 in terms of solid content).
~600 g/m 2 ), and a high viscosity liquid of 300 to 500 g/m 2 (solid content: 150 to 300 g/m 2 ). The dissolution treatment solution applied as described above is heated to 100 to 130℃ using a high-temperature steamer or the like.
A heat treatment is applied for about 30 minutes to promote dissolution, and the treatment solution is washed to obtain a raised product. (Example) The base fabric consists of weft polyethylene terephthalate staple No. 63 double yarn, warp polyethylene terephthalate staple No. 63 double yarn, and the pile yarn is
Made of a blend of PET150d/144f banlon yarn and PET130d/3f yarn, pile length 30mm, nap density 8000 pieces/cm 2
A low viscosity dissolution treatment solution with the following composition was applied uniformly (2000 g/m 2 ) to the pile fabric using the flat screen method, and then a high viscosity dissolution treatment solution with the following composition was applied to the same flat pile fabric immediately while it was still wet. It was uniformly deposited (1000 g/m 2 ) using a screen method. Due to this application, the low viscosity dissolving treatment solution extends approximately 15 to 20 mm from the tip of the nap, and the high viscosity dissolving solution extends approximately 3 to 5 mm from the tip of the nap.
It penetrated to about mm. Pile fabrics treated with two types of dissolution treatment solutions are
Then HTS 130℃ (humidity 75℃) without drying.
%) x 20 minutes, followed by washing with water and drying. The upright part of the obtained artificial fur is composed of long, thick prickly hairs and short, thin, and supple fluff, and the tips of both are thinned, making it look like natural hair without any loose or disordered fur. It closely resembled fur, and the texture of the nape surface was very soft.

The results are shown in Table 1.
