DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a flameproofing method for feathers.

[0002]

2. Description of the Related Art From the viewpoint of safety, clothes and bedding using a filling material are strongly required to be flameproofed. However, flameproofing of feathers is hardly practiced in practice, and even though there are patent publications on flameproofing of natural or synthetic fibers, examples of natural fibers include wool, alpaca, cashmere, mohair, and picuniya. , Guanaco, camels, silk,
In fact, it is limited to limbs, leather and human hair, and feathers are not illustrated. The specific volume of feather per g is 10
6.7 cc, whereas synthetic fiber used as the same filling is 90.7 cc and cotton is 87.8 cc. Therefore, the specific volume of the feather is high, that is, the heat retention from the bulkiness. Without the flameproof treatment that does not impair the height of the product, it will not be possible to meet the needs of consumers. However, feathers are extremely fragile, and in particular, the down does not have a feather axis, and the fine and flexible wings have a structure that extends radially, so it has the property of being very easily damaged by processing, The processing of the feather was rather shunned. Many flameproofing methods for mere natural fibers such as wool have been proposed in the past, and among these, flameproofing techniques using a treatment agent close to the present invention are disclosed in JP-B-49-30879 and JP-B-49-30879.

Japanese Patent Publication No. 52-12837 discloses the use of a water-soluble titanium compound and an N-methylol compound. However, once again, these techniques did not have very fragile articles, such as feathers, in mind.

[0003]

The present inventor has previously proposed a washing-resistant flameproofing method as disclosed in Japanese Patent Application No. 3-280808, while maintaining high bulkiness without damaging extremely painful feathers. An object of the present invention is to propose an improved method for further improving the effect.

[0004]

The present invention relates to: (a) a protein selected from the group consisting of collagen, gelatin, egg protein, plasma protein, casein and soybean juice, and (b) potassium titanium fluoride, sodium titanium fluoride and ammonium titanium fluoride. The present invention relates to a flameproofing method for feathers, which comprises treating feathers with a chemical containing a titanium fluoride salt selected from the group consisting of (c) oxycarboxylic acid and (d) an amino acid and / or a salt thereof. The reason why the flameproof performance with washing resistance can be obtained while maintaining the bulkiness of the feather according to the present invention is that the method of changing the titanium fluoride salt into a water-insoluble complex under strong acidity, and absorbing it into the feather, Shows good flame retardancy but no durability. Therefore, in the present invention, a drug that does not inhibit the bulkiness of feathers and does not reduce the flame retardancy was studied, and a protein selected from the group consisting of collagen, gelatin, egg protein, plasma protein, casein and soybean, It has been found that acids and amino acids are effective. When processing the titanium fluoride salt water-insoluble complex into a feather for the purpose of flame retardancy under strong acidity, by mixing an appropriate amount of the protein, the washing fastness is improved, and the bulkiness of the feather is inhibited. There was no adverse effect on flame retardancy. The reason is that when the water-insoluble complex of titanium fluoride is adsorbed on feathers, the protein covers the water-insoluble complex of titanium fluoride adsorbed on feathers, and the amino acids are complex of titanium fluoride. It acts as a cross-linking agent between the protein and the protein, and furthermore, the protein has an affinity for feathers, and it is considered that the adhesive force greatly contributes to the improvement of washing resistance. As described in the comparative examples as evidence, the insoluble matter fixing method using only the potassium titanium fluoride complex clearly shows the effect on the washing resistance. There are six types of gelatin from special grade to five types depending on the degree of purification, and four types of glue from high grade to gum tape. The protein used in the present invention preferably has no odor or coloration. The amount of the protein used is 5% to 80% with respect to feathers.
Is required, and if it is less than 5%, the durability is poor.
% Or more, the bulkiness of the feather becomes difficult. Preferably it is 10% to 50%. On the other hand, as the titanium fluoride salt, potassium titanium fluoride is particularly preferred. The use amount thereof is required to be 3 to 20% by weight, preferably 5 to 10% by weight based on the feathers. Also, the oxycarboxylic acid acts as another complexing agent and a stabilizer in forming a complex between the protein and the titanium fluoride salt in the flameproofing treatment bath, and prevents undesired precipitation,
It has the effect of strengthening deposition on feathers. As the oxycarboxylic acid, for example, citric acid, tartaric acid, malic acid, meso-oxalic acid and glycolic acid can be used as appropriate,
The amount used is 0.5 to 5 wt%, preferably 1 to 3 wt%, based on the feathers. Amino acids act as a cross-linking agent between gelatin and titanium fluoride salt, and this cross-linking action greatly improves washing resistance, and as shown in the data described below, the amount of titanium remaining in feathers The amount increases. As amino acids, α-amino acids, β-amino acids, γ
Any of amino acids, including aliphatic, aromatic, heterocyclic proteinaceous amino acids and non-proteinaceous amino acids, preferably those having 6 or less carbon atoms. Specifically, one amino group contains one carboxyl group, such as glycine and alanine, and one amino group has two carboxyl groups, such as aspartic acid and glutamic acid. Heterocycle-containing type such as histidine, which has multiple amino groups in a cyclic form, and furthermore, in addition to amino group and carboxyl group, types having other active groups, cysteine, methionine and the like can be appropriately used. it can. The salts of amino acid, the carboxyl group, may be mentioned Na, K, NH ₃ and C ₁ amine -C ₆ (methylamine, dimethylamine, trimethylamine, triethanolamine, etc.) and the like salts. For amino groups, mineral acids such as hydrochloric acid, sulfuric acid, nitric acid and phosphoric acid, and aliphatic and aromatic saturated unsaturated monocarboxylic acids and polycarboxylic acids, and similar oxycarboxylic acids and oxypolycarboxylic acids Acid or the like, preferably C
_Six or less acid salts may be mentioned. The amount used is 1.0 to 10.0% by weight, and preferably 2 to 5% by weight, based on the feathers. This treatment is carried out at a temperature in the range of 20 to 130 ° C. and a pH of 4 or less, preferably 2.5 to 3.0.
Is good. Suitable acids for this purpose are hydrochloric acid and phosphoric acid. As a preferred treatment method, at a temperature of 80 to 90 ° C., 4
The treatment is preferably performed for about 5 minutes, during which the exhaust to the feathers is completed, and a treated product having washing resistance is obtained.

【Example】

Example 1 A well-washed goose feather (90% down, 10% small feather) was treated with a solution containing the following agents. Gelatin 40% (w / w feather weight) Potassium titanium fluoride 5% (w / w feather weight) Phosphoric acid (85%) 5% (w / w feather weight%) Glycine 3% (w / w feather weight%) Citric acid 1.7% That is, after dissolving this agent in water 30 times the amount of feathers, the feather is immersed in the solution (in this case, 0.1% or less of a nonionic penetrant is used to compensate for the wetting). When the solution was immersed for 45 minutes, gelatin and potassium potassium titanium fluoride, glycine, and citric acid mostly exhausted to the feathers while forming a complex. Thereafter, the remaining drug was thoroughly washed and removed with water, and then dehydrated and dried. The treated feathers obtained in this way are different from the untreated feathers in terms of touch, bulkiness, color tone, etc., and have no significant change in value, and are extremely high in commercial value. It had flammability and bulkiness. Example 2 A well-washed goose down (90% down, 10% small feather) was treated in the same manner as in Example 1 with the following chemicals. Gelatin 40% (feather weight%) Potassium titanium fluoride 5% (feather weight%) Phosphoric acid 5% (feather weight%) Aspartic acid 3% (feather weight%) Citric acid 1.7% (feather weight) Table 1 shows the obtained results.
