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. Kosho 50-1759

No. 37 publication. In Japanese Patent Publication No. 49-30879,
The use of a complex compound of zirconium and an organic chelating agent or fluoride ion is disclosed in Japanese Patent Publication No. 50-17 / 1985.
No. 596 discloses the use of an aqueous solution containing an anionic titanium complex compound formed with an organic chelating agent or a compound capable of dissociating fluorine ions.
JP-20640 discloses the use of an anionic complex of tungsten under acidic conditions. 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]

An object of the present invention is to provide a washing-resistant flameproofing method which maintains high bulkiness without damaging extremely painful feathers at all.

[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. 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. Thus, in the present invention, a drug that does not inhibit the bulkiness of feathers and does not reduce flame retardancy was studied, and a protein selected from the group consisting of collagen, gelatin, egg protein, plasma protein, casein, and soybean was effective. I found that. 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 salt is adsorbed on feathers, the protein covers the water-insoluble complex of titanium fluoride salt adsorbed on feathers, and the protein has an affinity for feathers. It is considered that the adhesive strength greatly contributes to the improvement of the 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. Also,
The used amount of the protein is required to be 5% to 80% with respect to the feather. If it is less than 5%, the durability is poor, and if it is more than 80%, the bulkiness of the feather becomes difficult. Preferably 10
% To 50%. On the other hand, as the titanium fluoride salt, potassium titanium fluoride is particularly preferred. Its use amount is required to be 3 to 20% by weight based on feathers, and preferably 5 to 20% by weight.
-10 wt%. 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, glycolic acid, and the like can be used as appropriate. The amount of the oxycarboxylic acid is 0.5 to 5% by weight based on feathers, preferably 1 to 5%. 3 wt%. This treatment is performed at a temperature in the range of 20 to 130 ° C. and a pH of 4 or less, preferably 2.5 to 3.0. Suitable acids for this purpose are hydrochloric acid and phosphoric acid.
As a preferred treatment method, treatment is preferably carried out at a temperature of 80 to 90 ° C. for about 45 minutes, during which exhaustion to feathers is completed, and a treated product having washing resistance is obtained.

【Example】

Example 1 A well-washed goose down (70% down, 30% small feather) was treated with a solution containing the following agents. Gelatin 20% (vs feather weight%) Potassium titanium fluoride 5% (vs feather weight%) Hydrochloric acid (35%) 5% (vs feather weight%) Citric acid 1.7% (vs feather weight%) After dissolving the drug in water 30 times the amount of feathers, the feathers are immersed in the water (in this case, it is preferable to use a nonionic penetrant of 0.1% or less to compensate for the wetting), and the liquid is used. When immersed for 45 minutes, gelatin, potassium potassium fluoride, 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 have no significant change in hand, bulkiness, color tone, etc. from untreated feathers, are extremely high in commercial value, and have excellent washing resistance as shown in Table 1. It had flammability and bulkiness. Example 2 A well-washed goose down (70% down, 30% small feather) was treated in the same manner as in Example 1 with the following chemicals. Gelatin 20% (vs feather weight%) Potassium titanium fluoride 5% (vs feather weight%) Phosphoric acid 5% (vs feather weight%) Citric acid 1.7% (vs feather weight%) The results obtained are shown in Table 1. Shown in Example 3 A well-washed goose feather (down 70%, small feather 30%) was treated in the same manner as in Example 1 using the following chemicals. Gelatin 20% (w / w feather weight) Potassium Fluoride 5% (w / w feather weight) Sulfuric acid (98%) 5% (w / w feather weight%) Citric acid 1.7% (w / w feather weight%) It is shown in Table 1. Comparative Example 1 In order to prove the significance of the presence of the gelatin of the present invention, the same treatment as in Example 1 was performed by the following treatment method. Potassium titanium fluoride 10% (w / w feather weight) Hydrochloric acid (35%) 10% (w / w feather weight%) Citric acid 3.5% (w / w feather weight%) The results are shown in Table 1. Comparative Example 2 The feather of Example 1 was treated with the following agent described in JP-B-52-12837. Dimethylol ethylene urea 10 (wt%) Titanium tetrachloride (50% sol.) 5 (wt%) Water 85 (wt%) The results are shown in Table 1.
