Problems solved by technology

[0003] On the other hand, with the increase in the use of polyol fatty acid esters such as natural raw material components, there is a problem that the treatment agent components are cured at low temperatures due to seasonal factors, etc.
When the cured treatment agent is emulsified in water, the cured component is insoluble in water, and it is difficult to evenly attach the treatment agent to the yarn during yarn making, causing fluff / end breakage, resulting in a decrease in tube fill rate and post-processing Poor weavability / weaving in
Therefore, conventional processing agents for synthetic fibers have the problem of fluctuations in yarn-manufacturability such as fluffing and yarn breakage due to temperature changes such as seasonal factors.

Embodiment 1

[0129] The components described in Table 2 were mixed and stirred until uniform at 70°C to prepare a treatment agent (I). Using each of the processing agents (I) prepared above, the coagulation and the stability of the emulsion were evaluated by the following methods. The results are shown in Table 2.

Embodiment 2～47、 comparative example 1～17

[0131] In the processing agent (I) of Example 1, it evaluated similarly to Example 1 except having changed the processing agent component and its compounding quantity as described in Tables 2-5. The results are shown in Tables 2-5.

[0132] In addition, the figure of the processing agent component of Tables 2-5 shows the weight part of the non-volatile content of a processing agent. In addition, details of the components of the treatment agent are shown in Table 1 and below.

[0133]Table 1 shows the weight ratio of straight-chain fatty acid in the ester component constituting the structure having an ester bond formed by glycerin and straight-chain fatty acid, iodine value, hydroxyl value, acid value, and weight average molecular weight of the ester component. As the ester component, a naturally obtained ester may be purified by a known method, or the purified ester may be further separated and repurified by a known method using a difference in melting point, or a general com...

Abstract

　The objective of the present invention is to provide a synthetic fiber treatment agent capable of suppressing fluctuation in yarn manufacturing properties due to seasonal or other temperature variation, and minimizing fluff, yarn breakage, and the like. This synthetic fiber treatment agent is a compound containing an ester component (A) having a structure in which glycerin and a straight-chain fatty acid are ester-bonded, and at least one ester component (B) selected from an ester component (B1) having a structure in which polyglycerin and a fatty acid are ester-bonded, and an ester component (B2) having a structure in which sucrose and a fatty acid are ester-bonded, the straight-chain fatty acid including linoleic acid and a C14-22 straight-chain fatty acid other than linoleic acid, the proportion of the linoleic acid in the entire straight-chain fatty acid being 5-20% by weight, the total weight ratio of the linoleic acid and the C14-22 straight-chain fatty acid other than linoleic acid being 95% by weight or more, and the ester component (B2) having three or more ester groups within the molecule.

Description

technical field [0001] The present invention relates to a treatment agent for synthetic fibers and its utilization. More specifically, it relates to a synthetic fiber treatment agent used in the production of synthetic fiber multifilament yarn, synthetic fiber filament yarn provided with the treatment agent, and production of synthetic fiber filament yarn using the treatment agent Methods and fibrous structures comprising the synthetic filament yarns. Background technique [0002] Conventionally, mineral oil, esters of monohydric alcohols and fatty acids, and esters of polyhydric alcohols and fatty acids have been used as lubricants for synthetic fiber processing agents (for example, Patent Document 1). In recent years, it has been pointed out that the operating environment is deteriorating due to the fumes of low molecular components such as mineral oil, esters of monohydric alcohols and fatty acids due to the increase in heat treatment temperature and multi-yarn formation...
