The present invention relates to a fiber treatment agent. More specifically, the present invention relates to a fiber treatment agent that imparts a high degree of cohesiveness to fibers in the manufacturing and processing processes of synthetic fibers and is extremely effective in preventing fuzz yarn breakage in each process. In recent years, processes for manufacturing and processing synthetic fibers have become faster and more streamlined. For example, in the false twisting of polyester and nylon, high-speed stretching false twisting of 800 to 1000 meters/minute is now being put into practical use, compared to the conventional processing speed of about 100 meters/minute.
In this process, the fibers run while performing extremely high-speed rotational motion, resulting in intense friction with guides, twisters, etc., and single fibers being violently squeezed against each other, resulting in a dramatic increase in the number of fluffy yarn breakages compared to conventional methods. It has been pointed out that On the other hand, when weaving various fibers, the proportion of so-called non-sizing yarns (NSY) that omit the conventional warp sizing process is increasing, but it is difficult to obtain the same cohesiveness as sizing yarn, so it is a standard product that is easy to weave. The reality is that the application is limited to products. Generally speaking, to solve these problems, polymer oxyethylene/oxypropylene copolymers,
Methods of adding water-soluble polyamides, polyurethanes, and natural or synthetic waxes to spinning oils and fiber finishing oils have been proposed and put to practical use, but as described above, sufficient cohesiveness has not been obtained. Furthermore, the above-mentioned additives often cause problems such as increased friction, tar formation, or shedding of oil residue during processes such as spinning, drawing, knitting and weaving. The inventors of the present invention have arrived at the present invention as a result of intensive studies aimed at developing a fiber treatment agent that imparts a high degree of cohesiveness to fibers and also causes less of the above-mentioned problems. That is, the present invention is based on the general formula HO(A 1 O)l(CH 2 CH 2 CH 2 CH 2 O) n (A 2 O) o H
(1) [In the formula - (CH 2 CH 2 CH 2 CH 2 O-) n has an average molecular weight of 600
~3000 residues of polytetramethylene glycol;
A 1 O and A 2 O are oxyalkylene groups having 2 to 4 carbon atoms; l and n are oxyalkylene groups having 2 to 4 carbon atoms; l and n are oxyalkylene groups in which the sum of A 1 O and A 2 O is 30% by weight or more based on the average molecular weight of polytetramethylene glycol and It is an integer of 1 or more with an average molecular weight of 800 to 6000. (However, the content of oxyethylene groups in the total of A 1 O and A 2 O is 80% by weight or less.)
This is a fiber treatment agent characterized by containing a compound blocked by the following alkyl group, alkenyl group or acyl group. As the compound represented by the general formula (1), a compound having a structure in which an alkylene oxide having 2 to 4 carbon atoms (hereinafter abbreviated as AO) is added to polytetramethylene glycol (hereinafter abbreviated as PTMG) can be used.
Among commercially available PTMG obtained by ring-opening polymerization of tetrahydrofuran, the average molecular weight is
600 to 3000 can be applied. Particularly preferred are those having an average molecular weight of 800 to 2,400. PTMG
Even if one with an average molecular weight of less than 600 is used, the high degree of cohesiveness and prevention of fluff and thread breakage that are the objectives of the present invention cannot be obtained. In addition, the average molecular weight of PTMG is 3000
If it exceeds this range, the resulting compound becomes viscous and wax-like, impairing the smoothness essential to the fiber treatment agent, making it unsuitable for use. The number of carbon atoms represented by A 1 O and A 2 O in general formula (1) is 2 or more
Examples of the oxyalkylene group of 4 include oxyethylene group, oxyisopropylene group and oxyisobutylene group. Preferred oxyalkylene groups include a combination of an oxyisopropylene group and an oxyethylene group, and a combination of an oxyisopropylene group and an oxyisobutylene group. In general formula (1), l and n are the sum of A 1 O and A 2 O.
It is an integer of 1 or more such that it accounts for 30% by weight or more, preferably 40% by weight or more with respect to the average molecular weight of PTMG, and the overall average molecular weight is 800 to 6000, preferably 1100 to 5000. The sum of A 1 O and A 2 O is
If it does not reach 30% by weight of the average molecular weight of PTMG, the compound of general formula (1) has a high melting point and poor compatibility with other components, making it undesirable as a fiber treatment agent. Further, if the overall average molecular weight is less than 800, the focusing property aimed at in the present invention cannot be obtained. Furthermore, if the overall average molecular weight exceeds 6000, tension fluctuations are likely to occur during the spinning and drawing process. When two or more types of AO are used in the present invention, the manner of addition may be either random addition or block addition. However, when using oxyethylene group,
The proportion of oxyethylene groups in the total of A 1 O and A 2 O is 80% by weight or less. If the proportion of oxyethylene groups exceeds 80% by weight, uniform blending with other components becomes difficult. In a compound in which one or both of the terminal OH of the compound of general formula (1) is blocked with an alkyl group, alkenyl group, or acyl group having 18 or less carbon atoms,
Examples of alkyl groups of 18 or less include linear groups such as methyl, ethyl, propyl, octyl, decyl, lauryl, myristyl, cetyl, and stearyl, as well as isopropyl, isoamyl, and 2-ethylhexyl groups. , isotridecyl group,
Examples include branched ones such as isostearyl groups. Examples of the alkenyl group having 18 or less carbon atoms include allyl group, crotonyl group, and oleyl group. In addition, as an acyl group with a carbon number of 18 or less, the number of carbon atoms is
Carboxylic acids of 18 or less with OH removed, such as acetyl group, propionyl group, lauroyl group,
In addition to oleoyl groups, examples include dibasic acids such as adipic acid and succinic acid, with OH removed from one of the carboxyl groups. Among these groups, groups having 12 or less carbon atoms are preferred. When the number of carbon atoms in the above group exceeds 18, the heat resistance of the treatment agent decreases. Specific examples of the compounds described in the present invention include the following compounds. (A) PTMG1000 (EO/PO) random adduct (EO/PO=6/4, average molecular weight 3000) (B) PTMG2000 (PO) (EO) block adduct (EO/PO=3/7, average molecular weight 5000) ) (C) PTMG1000 (PO/BO) random adduct (PO/BO=6/4 average molecular weight 3000) (D) PTMG650 (EO/PO) random adduct (EO/PO=7/3 average molecular weight 1400) ( E) Monolaurate of (A) (F) Monomethylated product of (A) Note 1 PTMG1000 indicates PTMG with an average molecular weight of 1000. Note 2 EO stands for ethylene oxide, PO stands for propylene oxide, and BO stands for isobutylene oxide. Note 3 EO/PO=6/4 indicates that the weight ratio of EO and PO is 6:4. The fiber treatment agent of the present invention (hereinafter sometimes abbreviated as treatment agent) contains the above-mentioned compound, and the content thereof is not particularly limited unless it departs from the purpose of the present invention, but is usually 5 to 50% by weight, preferably is 10-40% by weight
It is. If the content of the above-mentioned compound is small, the convergence will be reduced, while if it is too large, the smoothness will be reduced. In the fiber treatment agent of the present invention, components other than the above-mentioned compounds include compounds conventionally known as fiber treatment agents, such as mineral oil, fatty acid ester,
A smoothing agent component such as EO/PO copolymer polyether, an emulsifier consisting of a nonionic activator or anionic activator, an antistatic agent, and other additives can be used depending on the purpose. The amount of the leveling agent component is usually 10 to 90% by weight, preferably 20 to 80% by weight, and the amount of other activators (emulsifier, antistatic component) is usually 5 to 40% by weight, preferably 10 to 30% by weight. %. Although there are no particular limitations on the target fibers for the treatment agent of the present invention, synthetic fibers such as polyester and nylon are suitable for manufacturing and processing thereof. When using the treatment agent of the present invention, conventional methods can be applied. For example, non-hydrated (undiluted solution)
or in the form of an emulsion emulsified with water, by a conventionally known lubricating method such as a roller lubricating method, a nozzle lubricating method, a spray method, a dipping method, etc., during the yarn-proofing process or any stage before weaving. The amount of the treatment agent deposited is usually 0.1 to 3.0% by weight, preferably 0.3 to 2.0% by weight based on the fiber. The treatment agent of the present invention imparts a high degree of cohesiveness to fibers and is extremely effective in preventing fuzz and yarn breakage in each step of yarn prevention, stretching, and processing. On the other hand, as a fiber treatment agent, it has appropriate smoothness and generates little tar on the hot plate. Furthermore, there is little oil scum or sticky matter falling off, making it possible to operate extremely smoothly, and the quality of the yarn obtained is also good. In particular, when used as a spinning oil for polyester POY-DTY, the oil adheres evenly during high-speed spinning and has excellent heat resistance, resulting in less fuzz during false twisting and a good quality processed yarn. . In addition, when used as a spinning oil or finishing agent for non-sizing yarn, processes such as spinning, drawing and warping proceed smoothly, and the number of stops due to warp yarn breakage during weaving is greatly reduced. The present invention will be further explained below with reference to Examples and Comparative Examples, but the present invention is not limited thereto. Examples 1 and 2 and Comparative Examples 1 to 3 12% aqueous emulsions of the inventive treatment agents and comparative treatment agents of Examples 1 and 2 and Comparative Examples 1 to 3 as shown in Table 1 were prepared and applied to polyester taffeta. Permeability was measured. Next, polyethylene terephthalate was melt-spun at a spinning speed of 3500 m/min, and the above emulsion was adhered to the spun yarn at a purity of 0.4%. The thus obtained 230 denier/36 filament POY (partially oriented yarn) was subjected to false twisting while being stretched using a circumscribed friction false twisting device at a draw ratio of 1.55, a heater temperature of 220°C, and a processing speed of 800 m/min. The degree of scum generation in the heater and the amount of fuzz in the obtained processed yarn were evaluated. The evaluation results are shown in Table-2. Compounds A, B, C, D, E used in Examples
