Description of the Related Art Conventionally, there is a non-twisted yarn having a structure in which a water-soluble vinylon filament is spirally wound around a cotton fiber bundle. It is manufactured by winding a water-soluble vinylon filament yarn around the surface of a normal cotton yarn from the direction opposite to the original twisting direction of the cotton yarn, while giving the cotton yarn a reverse twist and releasing the twist. are doing.

A strength is provided that does not cause yarn breakage or yarn breakage in the weaving process.

オルである。[0005] Conventional non-twisted yarns are used as pile yarns in the production of towels. The towel fabric manufactured using the non-twisted yarn as the pile yarn is then washed with water to dissolve and remove the water-soluble vinylon filament yarn. The towel obtained in this manner is a high-quality towel having a very soft feeling compared to a towel manufactured using ordinary cotton yarn as the pile yarn because the loop formed by the pile yarn has no twist.
【０００６】上記無撚糸は、高級なタオルの製造用には
適したものであるが、問題点もある。[0006] The above-mentioned non-twisted yarn is suitable for the production of high-quality towels, but has problems.
【０００７】第一の問題点として、価格が高いことが挙

が伴っている。[0008] The second problem is that when the above-mentioned non-twisted yarn is used, a water-based process cannot be used until weaving. This is because, when a water-based process is used, the water-soluble vinylon filament yarn is dissolved, and the strength of the non-twisted yarn is reduced. When manufacturing towels, a sizing step of gluing non-twisted yarns is essential in order to suppress fluff of pile yarns of the towels and prevent yarn breakage in the weaving process.
However, since the non-twisted yarn uses a water-soluble vinylon filament yarn, a sizing step using water cannot be adopted. For this reason, it is difficult to manufacture towels using non-twisted yarn.

加工することができる。For example, in the case of producing a towel fabric using a non-twisted yarn produced by using a cotton fiber as a fiber bundle and the above-mentioned cationic dyeable polyester as an auxiliary yarn as a pile warp of a pile cloth, the non-twisted yarn is insoluble in water. Therefore, the sizing step can be adopted without any problem, and the weaving process can be performed without causing fluff or yarn breakage.

The weft ground yarn used was a normal 20th count cotton yarn. Before being applied to the loom, a step of dipping and drying in a sizing solution composed of an aqueous solution containing polyvinyl alcohol by mass was performed.

A carbon cloth was produced using the carbon fiber non-twisted yarn produced in this manner. The obtained carbon cloth was treated with a 3% by mass aqueous solution of sodium hydroxide to dissolve and remove the non-twist yarn cationic dyeable polyester. Processing conditions were 90 ° C. for 60 minutes. The carbon fabric produced in this manner had less fuzz generated in the weaving process, had a good appearance when a composite was formed with a thermoplastic resin, and had a few fuzz defects.

もない。The non-twisted yarn of the present invention does not dissolve in water because it uses a cationic dyeable polyester yarn as a reinforcing yarn. For this reason, it can withstand the water-based treatment process sufficiently. Further, since the reinforcing yarn used in the present invention can be dissolved and removed under relatively mild conditions, it is easy to dissolve and remove, and the dissolving speed is high, so that the fiber bundle is not damaged.
