Embodiment 1

[0177] 6024 g of 40% by mass 3-allyloxy-2-hydroxyl-1-propanesulfonate aqueous solution (hereinafter, abbreviated as 40% HAPS) was charged into a 25 L capacity SUS reaction vessel equipped with a reflux cooler and a stirrer , Warming up to the boiling point reflux state with stirring. Then, under stirring, 5670 g of 80 mass % acrylic acid aqueous solution (hereinafter referred to as 80 % AA), 6024 g of 40 % HAPS, and 2128 g of 15 mass % sodium persulfate aqueous solution were added dropwise to the polymerization reaction system in the boiling point reflux state. (hereinafter abbreviated as 15% NaPS) (corresponding to 3.8 g of monomers in 1 mol of monomer components). Based on the time point at which 80% AA was added (0 min), 80% AA was added dropwise between 0 min and 90 min, and 40% HAPS was added dropwise between 0 min and 60 min at a constant rate. 15% NaPS as an initiator was added dropwise at an addition rate of 9.7 g / min, and the addition rate was changed to triple 29.1 ...

Embodiment 2

[0182] Using the fiber treatment agent (1) obtained in Example 1, fiber treatment was performed on polyester fabrics, and evaluations of washing durability and hygroscopicity were performed.

[0183] The results are shown in Table 1.

Embodiment 3

[0185] 350.8 g of deionized water was put in a 2.5-L capacity SUS reaction vessel equipped with a reflux cooler and a stirrer, and the temperature was raised to a boiling point reflux state while stirring. Then, under stirring, to the polymerization reaction system in the boiling point reflux state, 630.0 g of 80% AA, 545.0 g of 40% HAPS, 260.0 g of 100% 2-hydroxyethyl methacrylate (hereinafter referred to as 100% HEMA), 267.0 g of 15% by mass sodium persulfate aqueous solution (hereinafter abbreviated as 15% NaPS) (corresponding to 4.0 g of monomers in 1 mole of monomer components), 133.3 g of 45% hypophosphorous acid Sodium monohydrate (hereinafter, abbreviated as 45% SHP). Based on the time point (0 minute) when the addition of 80% AA was started, 80% AA was added dropwise at a constant rate between 0 minute and 180 minutes. For 40% HAPS, it was added dropwise at an addition rate of 6.06 g / minute between 0 minutes and 30 minutes, and was added dropwise at an addition rate ...

Abstract

The present invention provides a fiber treating agent with which it is possible to impart exceptional moisture absorption and desorption properties, and which excels in washing durability. This fibertreating agent includes a copolymer (A) having structural units (I) derived from carboxyl-group-containing monomers and structural units (II) derived from hydroxyl-group-containing monomers (b).

Description

technical field [0001] The present invention relates to fiber treating agents. Background technique [0002] Recently, there has been an increasing need to use dry fibers such as cellulose fibers and polyester fibers. A technique capable of imparting more excellent moisture absorption and release properties to such conventional dry fibers is required. [0003] Conventionally, techniques for imparting various functions by coating fibers with a fiber treatment agent are known (for example, Patent Document 1). However, fibers imparted with various functions by such coating have problems in that they have poor washing durability and that various functions are greatly degraded by washing. [0004] prior art literature [0005] patent documents [0006] Patent Document 1: Japanese Patent Laid-Open No. 2008-280652 Contents of the invention [0007] The problem to be solved by the invention [0008] An object of the present invention is to provide a fiber treatment agent ca...
