Embodiment 1～16 and comparative example 1～7

[0117] (1) Preparation of latex

[0118] The components shown in Table 1 and water were mixed, and the non-volatile components accounted for 20% by weight of the synthetic fiber treatment agent for papermaking in Examples 1-16 and Comparative Examples 1-7, respectively. Synthetic fiber treatment agent for papermaking. The obtained synthetic fiber treatment agent for papermaking was diluted with water so that the weight ratio of the non-volatile matter in warm water at a concentration of 25 to 60° C. was 0.4% by weight, to prepare emulsions. Using the obtained latex, evaluation was performed according to (2) of the following evaluation method. The results are shown in Table 2.

Abstract

Disclosed is a synthetic fiber treating agent for papermaking, which is capable of providing synthetic fibers for papermaking used for a paper-made nonwoven fabric with good dispersibility at low share, while suppressing the formation of air bubbles during a papermaking step. Consequently, the synthetic fiber treating agent for papermaking is capable of providing excellent fiber dispersibility. Specifically disclosed is a synthetic fiber treating agent for papermaking, which contains, as essential ingredients, a component A that is composed of a polyester compound obtained by polycondensing at least one dicarboxylic acid (derivative) selected from among aromatic dicarboxylic acids, aliphatic dicarboxylic acids having 4-22 carbon atoms and ester-forming derivatives thereof, and an alkylene glycol, a polyalkylene glycol or a derivative thereof, and a component B that is composed of a condensation product of a fatty acid and an alkanol amine.

Description

technical field [0001] The present invention relates to a synthetic fiber treatment agent for papermaking, a method for producing a synthetic fiber for papermaking, and a method for producing a nonwoven fabric for papermaking. Background technique [0002] Vinylon, rayon, natural cellulose, polypropylene, and polyacrylonitrile-based fibers have been widely used as synthetic fibers for papermaking. However, in recent years, in order to improve the so-called required performance, papermaking nonwoven fabrics (sometimes simply referred to as papermaking) obtained by making paper from the following synthetic fibers for papermaking with unique softness The raw material is a hydrophobic synthetic fiber such as polyolefin fiber or polyester fiber that has hand feeling, dimensional stability, heat resistance, and low cost. [0003] However, the current status quo is that practical products cannot fully exert the excellent performance of the hydrophobic synthetic fiber itself. Espe...
