Description

  The present invention relates to a treating agent for synthetic fiber filaments, a synthetic fiber filament provided with the treating agent, and a base fabric woven from the filament.

  In recent years, woven fabrics using synthetic fibers have been subdivided into applications such as airbags, tents and tarpaulins. In addition, the types of synthetic fibers used for these applications are becoming widespread, such as polyester fibers, polyamide fibers, aromatic polyamide fibers, or wholly aromatic polyester fibers.

  In general, a woven fabric is obtained through a scouring process after weaving synthetic fiber filaments to which a synthetic fiber treatment agent has been applied using a known loom such as a water jet loom loom or rapier loom. Then, it coats with resin, such as a water-repellent resin emulsion, and water repellency and airtightness are provided to a base fabric.

  When a general synthetic fiber such as polyester or polyamide fiber is woven at a high density, fluff is likely to occur due to abrasion between the fibers. In the case of high-strength and high-elasticity synthetic fibers such as aromatic polyamide fibers and wholly aromatic polyester fibers, fluff and fibrillation are likely to occur even when weaving at a low density.

  As a method for solving fuzz and fibrillation, it is disclosed that a specific ester compound is imparted to a fiber (Patent Document 1 and Patent Document 2). Certainly, this ester compound can reduce the fiber-to-fiber friction, and has an excellent performance of reducing fiber fluff by making the fiber soft. Therefore, it is used for the purpose of reducing fluff and fibrillation.

  However, when weaving a synthetic fiber filament to which a fiber treatment agent containing an ester compound described in Patent Document 1 is applied to fabricate a base fabric, it is coated with a resin such as a water-repellent resin emulsion after a scouring process.

Among these, since the elongation is low, fluff is likely to occur, and for the reason that the fluff reduction effect by the treatment agent is large, it is preferable to apply the treatment agent to the raw material synthetic fiber filament of 18 cN / dtex or more. The strength of the raw material synthetic fiber filament is more preferably 18.2 to 35 cN / dtex, and further preferably 18.5 to 30 cN / dtex.

  Specific preferred raw material synthetic fibers are preferably wholly aromatic polyamide fibers, wholly aromatic polyester fibers, and wholly aromatic copolyamide fibers because of the great effect of reducing fluff and fibrillation by the treatment agent. Aromatic polyamide fibers are more preferred because they are particularly effective in reducing fluff and fibrillation due to the treatment agent. The strength (cN / dtex) of the synthetic fiber was measured according to JIS-L-1013. (Gripping interval: 20 cm, tensile speed: 100% of the holding interval per minute)

  The raw material synthetic fiber filament itself is known. The method for producing the raw material synthetic fiber (spinning method) is not particularly limited, and known techniques and methods can be employed. For example, methods such as liquid crystal spinning, dry spinning, wet spinning, semi-dry semi-wet spinning, melt spinning, gel spinning and the like can be mentioned.

In the manufacturing method of the base fabric woven by the water jet loom, most of the treatment agent is removed by water pressure during weaving, so that the scouring process is omitted.

  Thereafter, in order to impart performance such as water repellency, hydrophilicity or airtightness to the base fabric, a resin emulsion according to each purpose is imparted. Examples of the resin emulsion include a fluororesin emulsion, a silicone resin emulsion, an acrylic resin emulsion, a water-repellent polyurethane resin emulsion, a hydrophilic polyurethane resin, and an ethylene-vinyl acetate copolymer resin emulsion. The method for applying these resins to the base fabric is not particularly limited, and known processes and methods can be employed.

Therefore, the resin is uniformly coated. Further, since the base fabric of the present invention has good scouring properties, the uniform coating property of the resin by the remaining treatment agent is not hindered, and the resin is uniformly coated. Therefore, the base fabric obtained by coating the base fabric of the present invention with a fluororesin emulsion, a silicone resin emulsion or a water-repellent polyurethane resin is excellent in water repellency and confidentiality.
