Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a treatment agent for cellulose fiber products or textile products mainly composed of cellulose fiber products, and particularly to a treatment agent characterized by imparting excellent wrinkle resistance to these products. It is something.

Conventionally, in order to impart wrinkle resistance to cellulosic fiber products or textile products mainly composed of cellulose fibers, for example, the fiber products were treated with a thermosetting resin having a methylol group in the molecule, such as methylol urea or methylol melamine. A treatment method is known, and textile products treated with this treatment have excellent washing resistance and wrinkle resistance, but this method generates formaldehyde, which is harmful to the human body, and this formaldehyde is only generated during the treatment process. Not, but
It occurs gradually at room temperature even after the treated textile products are washed.

For this reason, there was a major problem in that wearing treated items could cause skin irritation.

The present invention relates to a processing agent for textile products that solves the conventional problems as described above, and R3 is +CH2+ OfCH2CH20
R4 (where R4 represents a hydrogen atom or a monovalent hydrocarbon group, m represents an integer of 1 to 5, and n represents an integer of 1 to 100), X and y are each positive integers, provided that 4≦
x + y ≦ 8], and this product not only can provide excellent wrinkle resistance to textile products, especially cellulose fiber products, but also Since it does not have a methylol group in its molecule like other processing agents, it does not generate formaldehyde, which is harmful to the human body, so it has the excellent feature of not causing any hygiene problems when used.

To explain the present invention in more detail, the cyclic siloxane used as the main ingredient in the present invention is represented by the above-mentioned general formula (1), where R1 is a methyl group, an ethyl group, a proyl group, a butyl group, or a vinyl group. unsubstituted monovalent hydrocarbon groups such as phenyl groups, naphthyl groups, or substituted monovalent hydrocarbon groups in which some of the hydrogen atoms of the monovalent hydrocarbon group are substituted with halogen atoms, etc.; , R3 is fCH2−+O
fCH2CH20+R4 (here, R4 is a hydrogen atom or has the same meaning as R1 above, m is an integer of 1 to 5, n is 1
-100, preferably an integer of 5-50).

Moreover, X and y are each positive integers, and 4≦X.
+y≦8.

Such a cyclic siloxane can be easily produced, for example, by subjecting a cyclic alkylhydrodiene polysiloxane to an addition reaction of allyl glycidyl ether and polyoxyethylene allyl ether in the presence of a platinum catalyst.

Specific examples of such cyclic siloxanes include the following.

(X', y' are integers from 1 to 5, provided that 4≦X'+y'≦
(s, n are integers of 1 to 100) The textile processing agent of the present invention is a cyclic siloxane containing, for example, Mg (BF4)2, Zn (BF
4) After adding and mixing at least one catalyst selected from 2. amine compounds and water, the solution may be stirred to obtain a homogeneous solution. , catalyst 4-10 weight ratio, water 95
It is preferable to set the weight to 60.

When treating cellulose fiber products or textile products mainly composed of cellulose fibers using the textile treatment agent of the present invention, for example, the treatment may be carried out in the solution or aqueous emulsion prepared as described above. After soaking the textile product and squeezing it with a mangle,
Preliminary drying may be performed at around 0° C. for several minutes, then heating at approximately 150° C. for several minutes, followed by washing with hot water and water.

It should be noted that various additives such as stable emulsion type processing agents and sizing agents may be added to the processing agent of the present invention as necessary, as long as the purpose of the present invention is not impaired. Examples of the agent include formic acid, acetic acid, polyethylene, polyvinyl acetate, alkylethyleneimine compounds, and polyvinyl alcohol.

The treatment agent for textile products of the present invention is particularly suitable for cellulosic fiber products that tend to wrinkle and textile products obtained by blending or interweaving cellulose fibers with semi-synthetic or synthetic fibers.

The cellulosic fibers referred to in the present invention include natural cellulose fibers such as cotton and hemp, and regenerated cellulose fibers such as rayon, and are required to have hydroxyl groups bonded to kerosene residues of cellulose.

Example Preparation of cyclic siloxane Tetramethyltetrahydride-dienetic tetrasiloxane is subjected to an addition reaction with allyl glycidyl ether and polyoxyethylene allyl ether in various proportions in the presence of chloroplatinic acid, and X and y are each as shown below. Preparation of treatment solution for textile products as shown in Table 1 The cyclic siloxane obtained above, Mg(BF4)2, water, emulsifier (polyoxyethylene alkyl ether) and solvent (toluene) are shown in Table 2 below. A treatment solution for textile products was obtained by uniformly mixing the components in the following proportions (weight ratio).

Experiment 1 Each treatment solution prepared above (S-1 to S-10)
Soak a cotton broadcloth in the water, squeeze it with a mangle (
After wet pick-up (80%), the sample was pre-dried at 100°C for 2 minutes, and then heated at 150°C for 3 minutes.

Next, set this to 0. ! It was soaped in an aqueous solution of Monogen Ill/4 (trade name, manufactured by Daiichi Kogyo Seiyaku Co., Ltd.), then washed with hot water, further washed with water, and then dried to obtain a test cloth.

Next, the wrinkle recovery properties of the thus obtained test cloths in dry and wet conditions were examined in accordance with JIS L1079, and the results shown in Table 3 below were obtained.

Experiment 2 Test fabric treated in Experiment 1 above (Test Fabric Shop 4, 6.8

2 0 t1 After soaping in a household washing machine containing 40 g of Blue Chime (trade name, manufactured by Lion Oil Co., Ltd.), washing in hot water (5 minutes) and cold water (15 minutes),
It was then dehydrated and further dried at 100°C for 1 minute.

When this operation was performed once, three times, or five times, the wrinkle recovery properties in dry and wet conditions were examined according to JISL1079, and the results shown in Table 4 below were obtained.
