【0001】
【発明の属する技術分野】
本発明は制電性および解舒性に優れる弾性繊維用処理剤に関する。
【0002】
【従来の技術】
特公昭46−16312号公報には、一級アミンを配合した鉱物油からなる弾性繊維用処理剤が記載されている。特開平7−157969号公報には水溶性多価アルコールのEO付加物含有弾性繊維用油剤が記載されている。
特公昭51−37998号公報には、高級アルコールを添加した弾性繊維用油剤が記載されている。
【0003】
【発明が解決しようとする課題】
弾性繊維用処理剤は、シリコーン油、鉱物油およびエステル油などの疎水性のベースオイルを用いているために制電性を付与するために、極性の強い成分を多量に溶解させることが出来ず、制電剤を少量用いて若干の制電性を付与しているに過ぎない。また、解舒性については、高分子量の極性の強い成分や金属石鹸等の分散により向上させているのが現状である。
【0004】

BACKGROUND OF THE INVENTION
The present invention relates to a treatment agent for elastic fibers having excellent antistatic properties and unwinding properties.
[0002]
[Prior art]
Japanese Examined Patent Publication No. 46-16312 discloses a treatment agent for elastic fibers made of mineral oil containing a primary amine. Japanese Patent Application Laid-Open No. 7-157969 describes an oil additive for elastic fibers containing an EO adduct of a water-soluble polyhydric alcohol.
Japanese Examined Patent Publication No. 51-37998 describes an elastic fiber oil to which a higher alcohol is added.
[0003]
[Problems to be solved by the invention]
Since the treatment agent for elastic fibers uses hydrophobic base oils such as silicone oil, mineral oil and ester oil, it cannot dissolve a large amount of highly polar components in order to impart antistatic properties. Only a little antistatic property is imparted by using a small amount of antistatic agent. In addition, the unwinding property is currently improved by dispersing high molecular weight polar components and metal soaps.
[0004]
[Means for Solving the Problems]
In the present invention, as a base component, at least one selected from silicone oil, mineral oil, and ester oil is used. Water, a lower alcohol having a hydrocarbon group having 1 to 15 carbon atoms, and an alkylene oxide of the lower alcohol ( 1 to 5 mol) A processing agent for polyurethane elastic fibers containing 0.1 to 20% by weight of at least one selected from adducts and 0.1 to 10% by weight of an emulsifier. Moreover, this invention is a polyurethane elastic fiber characterized by the above-mentioned processing agent being 0.1-15 weight%.
[0005]
In the present invention, the base component is selected from ester oil, mineral oil, and silicone oil, and it is necessary to use at least one kind. The treatment agent of the present invention preferably has a viscosity at 30 ° C. of 3 to 30 mm 2 / s. If it is less than 3 mm 2 / s, volatilization of the treating agent becomes a problem, and if it exceeds 30 mm 2 / s, the smoothness is inferior. In this invention, 0.1-20 weight% of at least 1 or more types chosen from water, the lower alcohol which has a C1-C15 hydrocarbon group, and the alkylene oxide (1-5 mol) of this lower alcohol is contained. There is a need to. Preferably, it is 0.5 to 10% by weight. As for carbon number of the hydrocarbon group of a lower alcohol, 1-10 are preferred. The present invention controls the amount of water, lower alcohol and its modified product to deactivate isocyanate on the surface of the elastic fiber and improve the unraveling property of the cheese without substantially reducing the strength and elongation of the elastic fiber. In addition, the inventors have found that the antistatic property is improved by adding a highly polar component to the treatment agent. Specific examples of water, a lower alcohol having 1 to 15 carbon atoms and an alkylene oxide adduct of the lower alcohol used in the present invention include ion-exchanged water, soft water, hard water, methanol, ethanol, isopropanol, and butanol. , Hexanol, octanol, lauryl alcohol, phenol, methanol ethylene oxide 2 mol adduct, butanol ethylene oxide 4 mol adduct, propanol propylene oxide 3 mol adduct, lauryl alcohol butylene oxide 2 mol adduct, etc. . Among them, a low molecular weight compound having a molecular weight of 100 or less is preferable because the number of moles of active hydrogen increases per weight.
[0007]
In the present invention, the emulsifier is contained in an amount of 0.1 to 30% by weight. As the emulsifier, conventionally known various surfactants are used. The amount of the emulsifier added is preferably 0.5 to 15% by weight.
Specific examples of the emulsifier include EO adduct of alkylphenol, POE alkylamino ether, POE alkylamide ether, POE alkyl ester ether, POE dialkyl ester, glycerin monoester, glycerin triester amino-modified silicone, polyether-modified silicone, phosphoric acid Modified silicone, sorbitan monoester, sorbitan triester, PO / EO block diol alkane sulfonate salt, alkylbenzene sulfonate salt, dialkyl sulfosuccinate salt, alkyl sulfate salt, alkyl phosphate salt, POE alkyl ether phosphate salt, quaternary ammonium salt, 4 Grade phosphonium salts and the like.
[0008]
In addition, in order to enhance the smoothness and antistatic effect, 0.01 to 5 parts by weight of a higher fatty acid metal soap may be added to the treatment agent of the present invention. As the higher fatty acid metal soap, known ones conventionally used for elastic fibers can be used, and Ca stearate, Mg stearate, Al stearate, Ba stearate, zinc stearate and the like are preferable.
The treatment agent of the present invention includes conventionally known modified silicones (alkyl-modified silicone, ester-modified silicone, carbinol-modified silicone, carboxy-modified silicone, mercapto-modified silicone, epoxy-modified silicone, MQ silicone resin, MQT silicone resin, T Silicone resins, DT silicone resins, etc.), binders, antistatic agents, antioxidants, ultraviolet absorbers, and other components that are usually used for treating elastic fibers can be blended.
[0009]
The treatment agent of the present invention is usually applied in an amount of 0.1 to 15% by weight with respect to the elastic fiber.
[0010]
【Example】
The present invention will be specifically described below with reference to examples.
In addition, evaluation of each characteristic in a specific example was performed according to the following method.
[Evaluation method for the effect of oil]
Unwinding speed ratio:
In FIG. 1, the cheese (1) of the fiber which gave the processing agent to the unwinding side of the unwinding speed ratio measuring machine is set, and the winding side paper tube (2) is set.
After setting the winding speed to a constant speed, the rollers (3) and (4) are started simultaneously. In this state, there is almost no tension on the yarn (5), so the yarn is stuck on the cheese and does not leave, so the unwinding point (6) is in the state shown in FIG. By changing the unwinding speed, the unwinding point (6) of the yarn (5) from the cheese is changed, and the unwinding speed is set so that this point coincides with the contact point (7) between the cheese and the roller. The unraveling speed ratio is obtained by Equation 1. The smaller this value is, the better the unpacking property is.
[Formula 1]
Unwinding speed ratio (%) = (winding speed−unwinding speed) / unwinding speed X 100
Knitting tension:
In FIG. 2, the elastic yarn (9) vertically taken from the cheese (8) is passed through the compensator (10), the roller (11), and the roller (14) attached to the U gauge (13) via the knitting needle (12). And connected to a speedometer (15) and a take-up roller (16). The rotational speed of the take-up roller is adjusted so that the traveling speed of the speedometer (15) becomes a constant speed (for example, 10 m / min, 100 m / min), and the knitting tension at that time is taken up by the take-up roller. Is measured with a U gauge (13), and the friction (g) between the fibers / knitting needles is measured. The generated static electricity is measured with a Kasuga-type potentiometer (17) at 1 cm from the running yarn.
Roller static electricity:
Set cheese on the unwinding side of the unwinding speed ratio measuring machine, rotate it at a peripheral speed of 50 m / min, and use the Kasuga-type potentiometer to measure the generated static electricity 1 hour after starting rotation. taking measurement.
