Problems solved by technology

[0004] For example, in Patent Document 1, although a processing agent containing a polypropylene glycol-based polyol and a reaction product obtained by reacting a polypropylene glycol-based polyol with an organic diisocyanate compound has been disclosed, the adhesion of the processing agent deteriorates, Insufficient smoothness
[0005] In addition, in Patent Document 2, although a polyurethane elastic yarn winding body for diapers is described, it is characterized in that 2.5 to 5% by weight of mineral oil containing 70 to 90% by weight and polydimethylsiloxane is attached to the elastic yarn. 10 to 30% by weight of oxane treatment agent, but there are cases where the adhesion is insufficient

Embodiment 1～29、 comparative example 1～8

[0143] Reaction of polytetramethylene ether glycol with an average molecular weight of 1600 and 4,4'-diphenylmethane diisocyanate at a molar ratio of 1:2, followed by a dimethylformamide solution of 1,2-diaminopropane For chain extension, a dimethylformamide solution with a polymer concentration of 33% was obtained as a spinning stock solution. In addition, the concentration of the spinning stock solution was 1900 mPa·S (measurement temperature: 30° C.).

[0144] For the case that does not contain metal soap (calcium laurate, magnesium stearate), after mixing the components described in Tables 1 to 3, stir at 20 to 40°C for 30 minutes, for the case containing metal soap (calcium laurate, magnesium stearate), In the case of magnesium stearate), the metal soap after mixing and stirring was pulverized by the above-mentioned wet mill to obtain the elastic fiber treatment agents of Examples 1-29 and Comparative Examples 1-8, respectively. Components used in Examples and Comparativ...

Abstract

Provided are: a treating agent for elastic fibers that are excellent in terms of adhesion to hot-melt adhesives, unwindability, and smoothness; and elastic fibers that are excellent in terms of adhesion to hot-melt adhesives, unwindability, and smoothness. The treating agent for elastic fibers comprises a component (I) which is at least one compound selected from among higher alcohols, polyhydric alcohols having a valence of 3-6, alkylene oxide adducts of higher alcohols, and alkylene oxide adducts of polyhydric alcohols having a valence of 3-6 and a component (II) which is at least one oil selected from among mineral oils and ester oils, the weight proportion of the component (I) in the treating agent being 21-90 wt%.

Description

technical field [0001] The present invention relates to a treatment agent for elastic fibers and an elastic fiber provided with the treatment agent. Specifically, it relates to a processing agent for elastic fibers which is excellent in process passability and adhesiveness with a hot-melt adhesive, which is suitable for use in rubber parts related to sanitary materials such as paper diapers and feminine hygiene products. Background technique [0002] For the rubber part of the hygiene material, the elastic fibers used by bonding the overlapping cloths with a thermoplastic resin need to have good adhesion to hot-melt adhesives. Therefore, if an existing treatment agent is added to improve process passability such as unwinding and smoothness of elastic fibers, there will be problems such as reduced adhesiveness and damage to the function of the rubber part, and it is difficult to achieve both process passability and adhesion. sex. [0003] In recent years, along with the spe...
