Description

DETAILED DESCRIPTION OF THE INVENTION The present invention aims to improve productivity and product quality in spinning, I#, elongation and post-processing steps 1 by attaching a raw yarn oil containing a fluorine compound to synthetic wire InK. Extremely effective
Concerning a stain-resistant finishing agent that imparts excellent abrasion resistance and washing resistance to products after scouring and dyeing, while also imparting improved durable water and oil repellency and so-called stain resistance. .

Fabrics, % Pressure Fabrics containing synthetic fibers have strong lipophilic properties and are easy to get dirty, so various improvements have been made! Ta. General If: 11. The surface coach of the aqueous exclusive molecule, the Ing Kai is the parent, the aqueous upper part is grafted, ffl+1
According to 1c, there are two methods: one that makes dirt impervious to dirt and one that makes it difficult for dirt to stick to it. Fluorine compounds have conventionally been known as substances with excellent antifouling effects, and have become widely popular in the field of post-processing using 41IVC fluororesin, and demand for them is increasing. However, fluorine-based compounds are
Since K has a low intermolecular force and has a low surface free energy, it is possible to impart water cleanliness, oil repellency, and mold releasability by attaching K to the surface of a substance. This is a well-known fact. Among these fluorine compounds, fluororesins made from perfluoroalkyl compounds have been developed as materials that create surfaces with the lowest surface free energy and are expected to have good antifouling properties, and are used in carpets, waterproof clothing, and water pressure resistance. It is expected that it will be widely used mainly in the post-processing field for the production of pear materials that require it.

By the way, if the above-mentioned surface treatment process could be applied to bamboo at the spinning-crimping stage by using the thermal energy during the crimping process to impart durable antifouling properties, the price of drifting would increase. In an environment of rising costs, this will greatly contribute to reducing the total energy rookie cost required for product production. And antifouling properties K tf Z at the yarn stage
The following two fields can be considered.

1) A method in which the hollow-circle cross-sectional shape of the Rin #Kasuri constituting the fiber is compressed from the so-called resonance point of the zero-ilhide to make dirt less noticeable due to the diffused reflection of light.

2) From the viewpoint of so-called 1 soil release, a fluorine compound is added to the raw yarn oil, and it adheres during the spinning process and fixes the F component to the surface during the winding heat setting process, thereby reducing blushing energy and preventing stains. How to make it less colored.

It is.

At present, most of the addition of fluorine compounds to HIM is in the field of post-processing, and even if a post-processing agent containing a fluorine resin compound with an antifouling effect is applied at the yarn stage, it has no lubricating ability and cannot be used for spinning. , Hoshin, I@! It is impossible to achieve both productivity improvement and reduction in the -■ stage.

That is, when a post-nuclear finishing agent and an oil having lubricating ability are used together, the resin coating of the mosquito-repelling agent is plasticized by the oil component, resulting in a decrease in Wi, l value strength, and durable antifouling performance cannot be obtained. Furthermore, during the heat centrifugation process, resin components adhere to the nut roller, causing process troubles such as gum-up, fuzz, and wrapping. On the other hand, in order to solve the above problems in the spinning process, fluorine containing perfluoroalkyl groups (lower)
Using r-compound USP 4134839 as an example

(1, USP 4190545, and these methods have shown some degree of effectiveness.

However, the fluorine compounds described in the above specification have a high molecular density, a large specific gravity, and poor emulsion stability. Precipitation occurs, and the temperature is not high enough to fully demonstrate the performance of expensive fluorine compounds.

In order to solve this problem, the present inventors have proposed
As a result, the present invention has been achieved and is a success.

That is, the present invention is an anti-stain finishing agent which contains at least at least one fluorine compound represented by the following formula [T) or [II] to form a rut.

The branched chains or chain-like substances, and the substituted chains in the above general formula, are different even if they are the same. This stain-resistant beard treatment agent has an IvF characteristic of containing at least 43 weight units of the following:

Furthermore, to discuss this, llmK: K, which achieves the stain resistance effect of N1 by attaching an anti-stain finishing treatment agent, is a material that is emulsified into fine emulsion particles while the finishing agent itself exhibits sufficient water and oil repellency. It is important to adhere evenly to #11 fibers.

From this point of view, it is necessary for the finishing agent to have a group in each molecule that exhibits water and oil repellency, and a group that also exhibits intermolecular cohesive force and adsorption force, bonded to the mother nucleus. In this regard, in the present invention, due to the presence of 1000n B groups in the (+) fluorine compound, it adsorbs onto the fiber surface earlier than the oil component used in combination, and the synthetic iron fiber poly! An antifouling film is formed near the surface of the surface, and the oil is distributed in the top layer of the surface of the surface.
