Description

[Detailed Description of the Invention] The present invention can impart excellent flexibility and antistatic effect to clothing, etc., even when used in both the rinsing and drying steps in the washing process of textile products, such as clothing. The present invention relates to articles for processing textile products.

Conventionally, a common method for imparting flexibility to clothing has been to add a liquid fabric softener during the rinsing process of washing. However, with the spread of clothes dryers, from the viewpoint of simplifying washing operations and effective use of fabric softeners,
Various fabric softeners, in which an absorbent base layer is impregnated with a softening component, have been proposed as fabric softeners to impart flexibility and antistatic properties when drying damp clothing in a dryer after washing. . For example, an absorbent base layer with a specific absorbent capacity is impregnated with a textile softener having a melting point of 100°F to 170°F (Japanese Patent Publication No. 47-19594), a substrate such as a nonwoven fabric is coated with a waxy matrix, The outside of the fabric is coated with a fabric softener (Japanese Patent Publication No. 47-40120), and the melting point of di-long-chain alkyl-di-short-chain alkyl quaternary ammonium salt, which is one of the main fabric softeners, is lowered to improve usability. For the purpose of
This is an improved composition such as the combined use of a melting point depressant such as 4998). When these are used in a dryer, although they impart flexibility to clothing, they do not provide sufficient antistatic properties. Particularly in dryers, clothing made of synthetic fibers is significantly charged due to repeated friction between clothing, often causing discomfort to the user due to static electricity. It is also said that these softeners can be used in the rinsing process of laundry, but the softening effect is much inferior to that in a dryer, which is inconvenient for the user.

Therefore, the object of the present invention is to provide an article for treating textile products that can impart excellent flexibility and antistatic properties to clothing when used in both the rinsing and drying steps of the washing process. . The object of the present invention is to use a cationic fiber softener and a specific fatty acid amide compound to increase the proportion of voids occupied by these in the absorbent material (
By using a material impregnated so that the void occupancy (hereinafter referred to as "void occupancy rate") is within a specific range, the antistatic effect is improved, and when used in the rinsing process, the cationic fiber softener is facilitated in microparticle formation. This is based on the knowledge that it has the same excellent effect as when used in a dryer.

That is, the present invention provides an absorbent material with (3) a cationic fiber softener and a compound having the general formula (I) (wherein R1 is an alkyl group or alkenyl group having 7 to 15 carbon atoms, and n is 0 or (an integer of 1 to 2o, m is an integer of 1 to 20), and is impregnated with a fatty acid amide represented by: It is an article.

The absorbent material in the present invention may be any material that has a space within itself that can hold the cationic fiber softener and the fatty acid amide compound.

For example, paper, woven fabrics, non-woven fabrics, sponges, etc.

Among these, nonwoven fabrics and sponges are preferred from the viewpoint of usability.

Non-woven fabrics include those made of cellulose, rayon, polyester fibers, etc. treated with a binder, those mixed with polyolefin fibers without the use of a binder,
Spunbond cloth etc. can be used. The sponge is preferably a plastic foam such as polyurethane foam or polyester Baum having open cells. In addition, flexible sheet-like materials are preferable from the viewpoint of manufacturing and use, and in particular, the apparent specific gravity is 0.01 to 0.03, the porosity is 95 to 99%, and
Plastic platforms such as sheet polyurethane foam with a thickness of 1 to 5i+i or 10 to 50fI
/m, and a nonwoven fabric with a porosity of 70 to 90% is desirable.

Component (5) in the present invention can be any cationic fiber softener, various amine salts, quaternary ammonium salts, etc. that can impart flexibility to fibers. Among these, quaternary ammonium salts having two alkyl groups or alkenyl groups having 10 to 24 carbon atoms in the molecule are preferred, such as ammonium salts represented by the following general formulas (II) and (1), and amide ammonium salts. Salt, imidazolinium salt can be extracted.

(In formula 11.I, R2, R, and 3 each have 10 to 10 carbon atoms.
24 alkyl group, β-hydroxyalkyl group or alkenyl group, R4, R, 5 are each an alkyl group having 1 to 3 carbon atoms, hydroxyalkyl group or benzyl group,

It is one kind or a mixture of two or more kinds such as 1-methyl-1-((2-hexadecanoylamino)ethyl]imidazolinium methyl sulfate.

Component (B) in the present invention is a fatty acid amide represented by the above general formula (1). Specifically, lauroyl monoethanolamide, lauroyl jetanolamide,
Myristyloyldiethanolamide, valmitoylgetanolamide, octanoylgetanolamide, coconut fatty acid getanolamide, palm kernel fatty acid getanolamide, N-monosubstituted POE (P=2) coconut fatty acid amide, N-monosubstituted POE (P=10) Coconut fatty acid amide, N, N-disubstituted POE (total P=5) Coconut fatty acid amide, N, N-disubstituted POE (total P=20

Among these components (B), from the viewpoint of antistatic properties, the number of carbon atoms in the fatty acid is 9 to 15, particularly 1.
2 is preferable, and mono- or jetanolamide, N-mono-substituted POE (P=2
~3) Amides are preferred.

One of the features of the present invention is that a cationic fiber softener shown in the composition diagram and a fatty acid amide (component (B)) are used together as a base that imparts flexibility and antistatic properties to fibers. When used alone or in combination with component (5) and stearoyl jetanolamide, which is a compound similar to component (B), the product of the present invention does not produce any excellent effects. When using component (5) and component CB) together, the composition diagram and the blending ratio of (B) (
5) AB+ from 9515 to 40/60, preferably 951
It is desirable that the ratio be 5 to 60/40 (weight ratio).

Another feature of the present invention is that components (3) and (13) are impregnated within a specific volume range of the voids of the absorbent material. This is because if the amounts of components (5) and (B) are outside the range of the void occupancy of the absorbent material from 1 to 50 by volume, when used in the rinsing process of laundry, the same effect as in the dryer will not be achieved. .

When the absorbent material is a nonwoven fabric, it is particularly preferable that the void occupancy is 5 to 50 by volume, and in the case of a sheet-like plastic platform, it is 2 to 30 by volume. The porosity of the absorbent material is determined from the difference between the true specific gravity and the apparent specific gravity of the absorbent material, and then a mixture of component (5) whose specific gravity was measured by a conventional method is added to the mixture with a predetermined void occupancy. It was impregnated so that

The product of the present invention further contains a small amount of POE (P=1-10) alkyl (C8-18) ether, POE (P=1-10
) Alkyl (08-18) phenyl ether, carbon number 1
2 to 30 aliphatic carboxylic acids or esters thereof,
Fluorescent brighteners, dyes, pigments, fragrances, etc. may be added, but in such a way that the mixture of these and component diagram (B) has a void occupancy of the absorbent material in the range of 1 to 50% by volume. It is desirable to do so.

According to the product of the present invention, excellent flexibility and antistatic properties can be imparted to clothing, etc. even when used in both the rinsing process and the drying process of laundry. In particular, it has an excellent antistatic effect on clothing made of synthetic fibers such as acrylic fibers and nylon, and eliminates the discomfort caused by static electricity to the user.
