Description

Synthetic fiber treating agents and treating method of synthetic fiber

The present invention relates to a synthetic fiber treatment agent (hereinafter simply referred to as a treatment agent) and a synthetic fiber treatment method (hereinafter simply referred to as a treatment method). In the manufacturing or processing step of the synthetic fiber, in order to impart lubricity and antistatic property to the synthetic fiber, a treatment agent containing a lubricant and an antistatic agent is attached, but when the synthetic fiber is provided to a heat treatment step, for example, a flammable step, In this heat treatment step, it is important to prevent heater contamination due to heat weakening of the treatment agent in order to suppress the occurrence of lint or flakes and to obtain high quality false twisted yarn. The present invention relates to a treatment agent and a treatment method that can effectively prevent such heater contamination.

Conventionally, a mixture of a polyether compound, a polyorganosiloxane compound, and an ionic surfactant has been used as a treatment agent for preventing the above-mentioned heater contamination. As such a conventional processing agent, it is a polyorganosiloxane compound to mix, 1) Polydimethylsiloxane whose viscosity in 25 degreeC is 30 * 10 <^-6> m <2> / s or more, and the surface tension in 25 degreeC is 28 dyne / cm or less. Or fluoroalkyl-modified polydimethylpolysiloxane (special place 54-46923), 2) polydimethylsiloxane (special place 48-53093) having a viscosity at 30 ° C. of 15 × 10 ⁻⁶ m 2 / s or more, and 3) at 30 ° C.

By the way, these conventional treatment agents are insufficient in prevention of heater contamination in the heat treatment step, and particularly in the case of a combustible process such as using a short heater of 300 ° C. or higher, which the heat treatment step has been recently developed. There is a flaw. If the prevention of heater contamination in the heat treatment step is insufficient, lint or chippings may occur, thereby making it impossible to manufacture a high quality processed yarn.

The problem to be solved by the present invention is that, in the heat treatment step, particularly in the combustible step such as using a short heater of 300 ° C. or more, the heater contamination cannot be sufficiently prevented with the conventional treatment agent.

In addition, the present inventors have studied to obtain a treatment agent and a treatment method capable of sufficiently preventing the contamination of the heater in the heat treatment process of the synthetic fiber, especially in the combustion process such as using a short heater of 300 ℃ or more, polyether, As a treatment agent comprising a compound, a specific linear polyether modified polyorganosiloxane, and an ionic surfactant, a treatment agent containing the linear polyether modified polyorganosiloxane and an ionic surfactant in a predetermined ratio, respectively, is exactly suitable. It has also been found that it is precisely suitable to attach this treatment agent at a predetermined rate to the synthetic fibers used in the heat treatment step.
