Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a novel fiber product soft finish capable of imparting excellent flexibility to various fiber products, environmentally friendly and containing substantially no quaternary ammonium salt. The present invention relates to an agent composition and a method for preparing the same.

[0002]

2. Description of the Related Art Textile products such as clothes become hard and have an unfavorable texture due to repeated wearing and washing. Therefore, in order to improve this, in many households, during washing rinsing cycle, , Is treated with a softening finish. Currently, most of the commercially available finishing agents for household use are aqueous solutions containing a cationic surfactant, most typically a dialkyl type quaternary ammonium salt, for example, di-hardened tallow alkyldimethylammonium salt as a main component. It is a liquid product.

The principle of action of these softening agents is that the cationic surfactant is efficiently adsorbed on the surface of the fiber which is negatively charged in the rinse water, and the lipophilic site in the adsorbed surfactant molecule is used. Due to the lubrication effect, the friction coefficient of the fiber surface is lowered and the flexibility is exerted. Therefore, in order to secure a sufficient adsorption amount, a cationic quaternary ammonium salt has been preferably used.

However, although the above-mentioned dialkyl type quaternary ammonium salt has an excellent effect of imparting softness, its biodegradability when released into the environment is insufficient and the tertiary amine as a raw material is used as a quaternary salt. However, there is a drawback in that the manufacturing cost is inevitably high. Therefore, it is desired to develop a soft finish which does not have such drawbacks.

Although the nonionic surfactants such as glycerin and sorbitan fatty acid ester used in the present invention have good biodegradability, they are not positively charged in the rinse solution like cationic surfactants, and , Can not be adsorbed to the fiber efficiently. Therefore, when these nonionic surfactants are used as the main ingredient of the softening agent for textile products, it is necessary to devise a method for efficiently adsorbing them to the fibers.

As a solution to these drawbacks, Japanese Patent Laid-Open Nos. 56-26071 and 57-1762 are proposed.
In JP 61, a cationic softening agent is combined with a nonionic surfactant such as glycerin fatty acid ester. However, the dilong-chain alkyl-type quaternary ammonium salt as the cationic softening agent used is biodegradable. It is difficult and environmentally unfavorable. Further, the mono long-chain alkyl type quaternary ammonium salt described together has better biodegradability than the di long-chain alkyl type quaternary ammonium salt, but is still insufficient.
Although a protonated ethoxyamine is also used, it is used only in a small amount as a viscosity control agent or a stabilizer.

Further, in JP-A-52-148295, there is disclosed a composition in which a nonionic surfactant is combined with a cationic compound such as a quaternary ammonium salt, a polyamine salt, an imidazolinium salt or a pyridinium salt. Disclosure. However, as described in the publication,
Anion resistance is insufficient only with a non-ionic surfactant and a mono-long-chain alkyl-type quaternary ammonium salt of the above-mentioned cationic compound. It further requires a quaternary ammonium salt.

Further, in JP-A-5-156572, an ethoxylated amine is used in combination with a nonionic surfactant of pentaerythritol fatty acid ester. The nonionic surfactant is a polyhydric alcohol similar to glycerin fatty acid ester. However, it is not preferable because it has quaternary carbon that is difficult to biodegrade.

Furthermore, JP-A-5-195432, JP-A-5-195433 and JP-A-5-19.
In Japanese Patent No. 5436, a combination of a nonionic surfactant such as glycerin fatty acid ester and a mono long-chain alkyl amine salt is disclosed, but in all cases, the main ingredient is a di long-chain alkyl amine salt or a quaternary ammonium salt. And
These are only added in small amounts as auxiliary components.

[0026]

The present invention will be described in more detail by way of examples, which should not be construed as limiting the invention thereto.

Flexibility A commercially available cotton towel was repeatedly washed twice with a commercially available detergent, Hitop [Lion Co., Ltd., Climber trademark], and then rinsed under running water for 5 times to remove the detergent. A treated cloth was prepared. Next, assuming a detergent-derived anionic surfactant to be brought into the rinsing liquid, tap water containing commercially available straight-chain sodium alkylbenzenesulfonate having 12 carbon atoms in an amount of 0.0005 wt% or no additive The softening agent was added to the tap water in 0.022 wt% to stir, and the mixture was stirred at 25 ° C. and a bath ratio of 1/30 for 3 minutes for treatment.

Next, the towel treated by the above method was air-dried in a room and then left in a constant temperature and humidity room at 25 ° C. and 65% RH for 24 hours. The softness of these towels was evaluated by eight skilled panelists based on the following criteria. 4: Equivalent to comparative composition (1) (di-hardened tallow dimethylammonium chloride) 3: Harder than comparative composition (1) and softer than comparative composition (2) (mono-hardened tallow trimethylammonium chloride) 2: Comparative composition Equivalent to product (2) 1: Equivalent to untreated Both Comparative composition (1) and Comparative composition (2) are treatment liquids diluted with tap water without addition of sodium linear alkylbenzene sulfonate, and used for cotton towels. Processed. The higher the score, the better the flexibility.

Example 1 Using the mono-long chain alkyl type amine shown in Table 1, a soft finish having the composition shown in Table 2 was prepared as follows. That is,
A non-ionic softening agent and a mono long-chain alkyl type amine are melt mixed to form a homogeneous mixture, and in the case of a composition containing amine, water containing equimolar hydrochloric acid to the amine is added to this mixture with stirring. In addition, a dispersion was prepared. Then, the softness when treating a cotton towel with a treatment liquid prepared by diluting these softening finish compositions with tap water or tap water containing a linear sodium alkylbenzene sulfonate was judged according to the above criteria. The results are shown in Table 2.

[Table 1]

[Table 2]

As shown in Table 2, in Comparative Compositions (3) and (6), the softening effect was insufficient even with the treatment liquid containing no anionic surfactant, and Comparative Compositions (4) and (5) In contrast, while the softening effect is deteriorated by the addition of the anionic surfactant, the composition (1) of the present invention is excellent in the softening effect regardless of the addition of the anionic surfactant.

Example 2 Using the mono-long-chain alkyl type amine shown in Table 3, a softening finish having the composition shown in Table 4 was prepared in the same manner as in Example 1, and sodium linear alkylbenzene sulfonate was added. The softness when a cotton towel was treated with the treatment liquid diluted with the above tap water was judged according to the above criteria. The results are shown in Table 4.

[Table 3]

[Table 4]

As can be seen from Table 4, when the monoionic long-chain alkyl type amine is used in combination with the nonionic softening agent of the compositions (2) to (13) of the present invention, sodium linear alkylbenzenesulfonate coexists. However, the softening effect is excellent. However, even when a mono long-chain alkyl type amine having a too long polyoxyethylene chain is used together as in the comparative composition (7), the effect of the present invention cannot be obtained. In addition, in this example, a monoalkyl amine (1),
The alkyl group of (4), (5) or (9) to (13)
Even if the stearyl group is changed to an oleyl group or an alkyl group of beef tallow fatty acid, hardened beef tallow fatty acid, palm oil fatty acid, or the alkyl groups of monoalkyl amines (3), (6), (7) and (14) are hardened beef tallow. Even if the alkyl group of the fatty acid is changed to the beef tallow fatty acid, the alkyl group of the palm oil fatty acid, the stearyl group, or the oleyl group, the same excellent softening effect can be obtained. Further, even if sulfuric acid is added in an equimolar amount to the amine instead of hydrochloric acid, hydrochloric acid or sulfuric acid is added to the amine in an amount of 0.
The same excellent effect can be obtained by adding 5 times or 1.5 times mol.

Example 3 A soft finish having the composition shown in Table 5 was prepared in the same manner as in Example 1, and a cotton towel was treated with a treatment solution diluted with tap water containing sodium linear alkylbenzenesulfonate. The flexibility when treated was judged according to the above criteria. The results are shown in Table 5.

[Table 5]

As can be seen from Table 5, in the compositions (14) to (26) of the present invention, mono long-chain alkyl type amine is added to glycerin fatty acid ester, diglycerin fatty acid ester, sorbitan fatty acid ester, sorbitol fatty acid ester, methyl glucoside. When a fatty acid ester or glucose fatty acid ester is used in combination, the softening effect is excellent. Further, in this example, even if sulfuric acid is added in an equimolar amount to the amine instead of hydrochloric acid, or hydrochloric acid or sulfuric acid is added in an amount of 0.5 times or 1.5 times the amount of amine, similarly excellent flexibility is imparted. The effect is obtained.

Example 4 A soft finish having the composition shown in Table 6 was prepared in the same manner as in Example 1, and a cotton towel was treated with a treatment solution diluted with tap water to which sodium linear alkylbenzenesulfonate was added. The flexibility when treated was judged according to the above criteria. The results are shown in Table 6.

[Table 6]

As can be seen from Table 6, a nonionic softening agent or mono-long chain alkyl type amine rich has a small softening effect, but the weight ratio of these components is 7: 3 to 3:
7 shows a good softening effect, and further 4: 6 to
A better effect is obtained than in the case of 6: 4. In addition, even if sulfuric acid is added in an equimolar amount to the amine instead of hydrochloric acid in the examples, hydrochloric acid and sulfuric acid are added in an amount of 0.5 times mol or 1.5 times the amine.
The same excellent softening effect can be obtained even if the amount is doubled.

Example 5 A softening agent having the composition shown in Table 7 was prepared by forming a dispersion in the same manner as in Example 1 and further adding other components, followed by addition of sodium linear alkylbenzenesulfonate. The softness when a cotton towel was treated with the treatment liquid diluted with the above tap water was judged according to the above criteria. The results are shown in Table 7.

[Table 7]

As can be seen from Table 7, even if a viscosity modifier, a stabilizer, a solvent and the like are added to the nonionic softening agent and the monoalkyl type amine, the same excellent softening effect can be obtained.
