Description
Technical field
The present invention relates to processing method, the synthetic fiber of synthetic fiber, spinning method and the spun yarn of synthetic fiber.In recent years, in the spinning of synthetic fiber, in order to realize the reduction of production cost, the raising of productivity ratio, advance to the conversion of high speed ring spinning, the high-speed spinning such as high speed rotor formula free end is spinning, eddy current air is spinning.But when spinning speed high speed, the unit interval becomes many pro rata by fibre weight and the speed of spinning machinery like this, thereby scum silica frost (ス カ system) increases in the accumulation of the mechanical material portion of spinning machinery, and cleaning period shortens, and workability reduces.Thereby the present invention relates to suppress in the high-speed spinning of synthetic fiber scum silica frost synthetic fiber contact and the accumulation of the mechanical material portion of the spinning machinery that passes through to synthetic fiber give the processing method of the synthetic fiber of excellent high-speed spinning, the synthetic fiber that obtain by this processing method, the spinning method of these synthetic fiber and the spun yarn obtaining by this spinning method.
Background technology
In the past, in the spinning of synthetic fiber, conventionally used the various finishes that contain potassium alkyl phosphate.Described finish is known 1) the 2 composition systems (for example, with reference to patent documentation 1) of potassium alkyl phosphate and alkyl amino ether type nonionic phosphoric acid corrective; 2) the 3 composition systems (for example, with reference to patent documentation 2) of the polyoxyethylene compound of potassium alkyl phosphate, the non-ionic phosphoric acid corrective of alkyl amino ether type and high molecular; 3) 2 composition systems of the polyoxyethylene compound of potassium alkyl phosphate and high molecular (for example, with reference to patent documentation 3); 4) 3 composition systems of potassium alkyl phosphate, Emulsification of Paraffin thing and cationic surface active agent (for example, with reference to patent documentation 4) etc.But, while using these existing finishes, there are the following problems: in high speed ring spinning, scum silica frost is piled up in balloon controller (anti-node ring), or be piled up in rotor at the spinning middle scum silica frost of high speed rotor formula free end, and then be piled up in rotating shaft (ス ピ Application De Le) at the spinning middle scum silica frost of eddy current air.Wherein, go out speed with the silk spinning during high speed ring spinning, high speed rotor formula free end are spinning compared with, it is significantly fast that the silk spinning during eddy current air is spinning goes out speed, therefore to pile up this problem large for scum silica frost.When scum silica frost is piled up like this, not only correspondingly cleaning period shortens, workability reduces, and fiber is subject to significantly damage and a strength decreased or white powder, fracture of wire are significantly increased.
