The resultant treating agent is excellent in emulsification and dispersion stability. The aforementioned treating agent is capable of imparting excellent smoothness, etc., to various fibers and preventing fiber strength from deteriorating by resin finish.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a treatment agent for textiles. More specifically, it provides smoothness and flexibility, prevents fiber strength from decreasing due to resin processing,
This invention relates to a treatment agent for fibers used for purposes such as preventing thread breakage during sewing (sewability).

[Prior Art] Fiber processing agents containing fatty acid esters of polyhydric alcohol alkylene Oquinde adducts, polyhydric alcohol fatty acid esters, and fatty acid alkanolamides as essential components of surfactants are conventionally known. (Tokuko Showa 57-
19225 Publication) [Problems to be Solved by the Invention] However, in order to make this emulsion dispersion stable enough to be used as a treatment agent for fibers, the amount of wax contained in the emulsion dispersion must be increased. There was a problem that the amount could not be increased sufficiently, and therefore sufficient properties, especially sewability, could not be imparted.

[Means for Solving the Problems] As a result of intensive studies to solve the above problems, the present invention has been arrived at. That is, the present invention provides at least one wax (A) selected from the group consisting of hydrocarbon waxes, oxides thereof, and animal and vegetable waxes, and a surfactant component (

In consideration of emulsification and dispersibility, glycerin, pentaerythritol, sorbitol, or their intramolecular condensate alkylene oxide (
Containing ethylene oxide in an amount of 50% by weight or more) No. 2
~30 molar adducts (single, random, block adducts)

(b2) is a polyhydric alcohol listed in (b+) and usually has 8 or more carbon atoms (preferably 10 carbon atoms).
Esters (partial or complete esters) of ~28) with saturated and/or unsaturated fatty acids (e.g. caprylic acid, lauric acid, stearic acid, oleic acid, coconut oil fatty acids)
, or two or more of these. Considering good points such as smoothness and flexibility, preferred among these are glycerin, pentaerythritol, sorbitol, and stearic acid or oleic acid esters of their intramolecular condensates.

(b3) is a mono- or dialkanolamine (
Examples include so-called fatty acid alkanolamides, which are condensates of monoethanolamine, jetanolamine, monoisopropanolamine) and the fatty acids listed in (bl), usually having 8 or more carbon atoms. The fatty acid alkanolamide may contain an excess of mono- or dialkanolamine. Among these, in consideration of emulsifying and dispersing properties, preferred are monoethanolamine, jetanolamine, monoisopropanolamine, and fatty acids such as lauric acid, stearic acid, oleic acid, and coconut oil fatty acid. Particularly preferred alkanolamides are fatty acid alkanolamides of jetanolamine, monoisopropanolamine, etc., and lauric acid, coconut oil fatty acid, etc.

Examples of (b4) include compounds represented by the general formula % (1) (wherein R is a fatty acid residue having 8 or more carbon atoms, and m is an integer from 1 to 5). In general formula (1), the fatty acids constituting the fatty acid residue (referring to a fatty acid with a carboxyl group removed) having 8 or more carbon atoms (preferably 10 to 28 carbon atoms) include saturated and unsaturated fatty acids.

Furthermore, the processing agent of the present invention may further contain a surfactant (D) other than the above. By containing (D), compatibility with abasic salts and emulsion dispersion stability when using hard water can be improved.

Examples of (D) include nonionic surfactants such as propion oxide-ethylene oxide block copolymers and polyoxyalkylene alkyl ethers.

The fiber treatment agent of the present invention contains (A), (B) and, if necessary, (C) and (D). (A) and (B

-90: 50-10 (weight ratio). If (A) is less than 30, smoothness tends to deteriorate, and if it exceeds 90, it is difficult to emulsify and disperse.

For the total weight of (B), (C), and (D), (
B) is usually 50 to 100% by weight. Preferably 60
~100% by weight. If the total amount of these is less than 50% by weight, the stability of the emulsified dispersion will be poor.

b4) is usually 0 to 80% by weight, preferably 20 to 70% by weight.

If (b1), (b2), (b2), and (b4) are each outside the above range (normal range), the stability of the emulsified dispersion decreases.

Other additives, such as preservatives and fungicides, sizing agents, etc., can also be added to the fiber treatment agent of the present invention.

The method for applying the fiber treatment agent of the present invention to textile products is the same as that for conventional fiber treatment agents, in which emulsification and dispersion is carried out in advance in a usual manner, and the emulsion dispersion (concentration is 10
~50% by weight) and then diluted with water (concentration is 0.001 to 1.0% by weight in terms of solid content) or diluted with a solvent (concentration is 0.001 to 1.0% in terms of solid content) 1
．． A treatment bath may be prepared using a method such as 0% by weight), and the textile product may be immersed or padded in the bath and then squeezed and dried. The amount when adhering to textile products is usually 00OO1 to 2.0 g in terms of solid content per 100 g of dry textile products.

[Effects of the Invention] When the fiber treatment agent of the present invention is used, for example, as an emulsified dispersion, it has a sufficiently higher wax content than conventional treatment agents, so it has sufficient performance (smoothness and smoothness) compared to conventional treatment agents. etc.) can be given.

Furthermore, since the emulsified dispersion of the fiber treatment agent is extremely stable, the emulsified and dispersed particles are not destroyed by mechanical impact such as forced circulation of the treatment bath using a pump. Therefore, it can always be uniformly processed into textile products using any textile processing machine. It also prevents a decrease in fiber strength due to resin processing.
