[0003] However, synthetic fibers, especially synthetic fibers containing polyolefin-based resins such as polyethylene resins and polypropylene resins (sometimes referred to as polyolefin-based fibers), are hydrophobic, which is different from natural fibers such as cotton and cellulose-based fibers. Compared with rayon, it is less hydrophilic

Embodiment 1

[0121] High-density polyethylene (commercial product) with a melting point of 130°C before spinning, a melt flow rate of 20 g / 10 minutes measured at a temperature of 190°C and a mass of 2.16 kgf in accordance with JIS K6922-1, and a density of 0.952 was used. name: Nipolon Hard OS02H, manufactured by Tosoh Corporation), and polyethylene terephthalate (trade name: HY-01, Hengyi (HENGYI)), spin out polyethylene terephthalate resin and polyethylene terephthalate resin from the spinning nozzle of the discharge hole with a diameter of φ0.35 according to the mass ratio as the core component: sheath component = 60 / 40 The vinyl resin was melt-spun at a drawing speed of 1200 m / min to obtain a core-sheath type composite undrawn yarn with a fineness of 5.4 dtex.

[0122] Next, this undrawn yarn was subjected to a wet drawing treatment at a drawing temperature of 80° C. and a draw ratio of 2.67 times to form a drawn yarn. The two components were mixed at the mixing ratio shown in the col...

Embodiment 2～7

[0124] (Examples 2-7, Comparative Examples 1-6, Reference Examples 1-3)

[0125] As the fiber treatment agent, those prepared by mixing the components at the ratios described in the columns of Examples 2 to 7, Comparative Examples 1 to 6 and Reference Examples 1 to 3 shown in Table 1 were used. Fibers were obtained by the same steps as those used in Example 1 to make thermally bonded non-woven fabrics, and the adhesion of the treatment agent to the surface of the fibers was obtained by the aforementioned method. The results are described in Table 1. It should be noted that, in Examples 6 and 7, the oil agent containing 25% by mass of polyglycerin was used as the polyglycerol of b-3 to prepare the fiber treatment agent, but the ratio and adhesion of the component (b) in Table 1 Quantities are reported based on the amount of polyglycerin, not oil.

Abstract

The purpose of the present invention is to provide a highly hydrophilic synthetic fiber. The present invention pertains to the synthetic fiber in which (a) mannosylerythritol lipid (MEL) and (b) at least one glycerin compound selected from the group consisting of (poly)glycerin, (poly)glycerin fatty acid ester, and (poly)glycerin alkylene oxide adduct are adhered to the surface of the fiber.

Description

technical field [0001] Technologies related to synthetic fibers, fiber treatments and their utilization are disclosed. Background technique [0002] Compared with natural fibers, synthetic fibers have superior mechanical properties and chemical resistance, so they are mainly used in the form of non-woven fabrics as liquid impregnated sheets such as soft wet tissues, wet wipes, and facial masks, cosmetic / medical The surface layer of various hygiene products such as patches, disposable diapers, and sanitary napkins. [0003] However, synthetic fibers, especially synthetic fibers containing polyolefin-based resins such as polyethylene resins and polypropylene resins (sometimes referred to as polyolefin-based fibers), are hydrophobic, which is different from natural fibers such as cotton and cellulose-based fibers. Compared with rayon, the hydrophilicity is low. Therefore, when synthetic fibers are used as the above-mentioned liquid-impregnated sheet or surface sheet for sanit...
