JP2923922B2 - Bedding - Google Patents

Description

Description: BACKGROUND OF THE INVENTION The present invention relates to bedding and, more particularly, to bedding in which rot such as feathers and wool and odor are prevented.

[Conventional technology and problems]

Feathers are generally composed of keratin protein whose surface is covered with natural grease.Since this natural grease is easy to get moldy and has a strong smell of birds, when used as a filler for bedding, A natural grease has been removed in advance using a surfactant.

However, the removal of natural grease introduces a new problem that the feathers are more likely to get germs. Penicillium is a representative of molds on feathers,
Aspergillus, Cladosporium (C
Ladospolium, Alternaria, Phoma, etc. all produce pigments. Also,
Pseudomonas aeru (Pseudomonas aeruinosa) is a representative of bacteria that adhere to feathers from which natural grease has been removed.
ginosa, Pseudomonas aeruginosa), Serratia marcesans (Serratia m)
arcescens germs, Alcaligenes bouqueri (Alcalig)
enes bookeri Bacillus subtilis). These are considered to decompose the keratin protein and generate odor and foul odor. The above phenomenon is the same not only for feathers but also for other animal fibers such as wool, alpaca, vicuna and the like containing keratin protein as a main component.

On the other hand, bedding, polyurethane foam, and mattresses using polyethylene foam filled with natural cotton or synthetic fiber have been used for many years due to moisture and waste products radiated from the human body during sleep, and furthermore, the propagation of bacteria. It gives off an unpleasant odor while you are there. Such a phenomenon not only hinders good sleep, but is also unsanitary and causes the durability of bedding to be significantly reduced.

[Means for solving the problem]

The present inventor has conducted intensive studies in view of such circumstances, and as a result, has found that the above problem can be solved by incorporating microorganisms that inhibit the growth of harmful microorganisms such as malodors into bedding, and arrived at the present invention.

That is, the present invention includes a bedding incorporating an aerobic microorganism that inhibits the growth of harmful microorganisms such as odors.

Microorganisms used in the present invention that inhibit the growth of harmful microorganisms such as foul odors include "Bio Magic Powder",
"Bio magic tape" (all trade names, manufactured by L & G Co., Ltd.) and the like can be mentioned. The former is literally powdery and the latter is tape-like.

Examples of the bedding in the present invention include feathers, bedding using animal fibers such as wool, plant fibers such as natural cotton, and chemical fibers such as polyester and polyamide as fillers, mattresses made of polyurethane foam, polyethylene foam and hard materials. So-called health mattresses, etc., which are made by combining polyethylene foam as a flexible material with polyurethane foam or cotton, as well as blankets, sheets,
Pillows, cushions, etc. are also included.

As a method for incorporating aerobic microorganisms that inhibit the growth of harmful microorganisms into bedding, for example, a material obtained by dissolving or suspending biomagic powder in water, a dipping method, a filler such as feathers by a spray method, a polyurethane foam, Foams such as polyethylene foam, as well as side fabric and exterior packaging,
A method of adhering and applying to the surface of a blanket, a sheet, or the like, followed by drying. In this case, carbohydrates, lipids, and other assimilating substances can be added. Alternatively,
An aqueous solution or suspension containing the biomagic powder is applied to cloth, nonwoven fabric, paper, or the like by the above-mentioned dipping method, spray method or the like, and then dried and then placed in a filler. For example, there is a method of sticking it to the surface of the body. In this case, the bio magic tape can be cut into an appropriate size and used as it is. In addition, it can also be incorporated into the inner bag or the side cloth that stores the filler by the above method.

Furthermore, in the case of a pillow, a cushion or the like, it may be incorporated into the filler or the side cloth by the same method as described above.

The bedding of the present invention is a top and bottom set, and further, by using these in combination with a blanket, sheets, pillows, etc.
More effective effects can be obtained.

〔Example〕

Hereinafter, the present invention will be described in more detail with reference to Test Examples and Examples, but the present invention is not limited thereto.

Test Examples I to III It was examined what kind and how many microorganisms exist in feathers. At the same time, biomagic powder and biomagic tape were also examined.

Test method: The test was carried out using a thioglycol medium for bacterial tests (culture temperature of 30 to 32 ° C) and a glucose peptone medium for fungal tests (culture temperature of 22 to 25 ° C) specified in the Japanese Pharmacopoeia Act, 11th revised edition 39 Sterility test method.

A certain amount of feathers was weighed, and cultured using a standard agar medium for measuring the number of viable bacteria (culturing temperature: 36 ° C., 48 hours).

Culture results: shown in Table 1.

Test Example IV Biomagic powder and biomagic tape were used to examine the effects of removing odors caused by bacteria and the effects of preventing the generation of odors.

Using thioglycollate medium I and trypto soy Pui Yung medium, at a temperature of cultivation temperature 30 to 32 ° C., bio Velcro, bio magic powder, feather bacteria respectively enrichment, and culture, about ¹⁰³ U / ml Each of the culture media was added to the bacterial solution so as to be prepared.

i) Odor removing effect Three test tubes containing 15 ml of a germ solution of a stinking feather were prepared, and 1 ml of a biomagic tape solution and 1 ml of a biomagic powder solution were added to each test tube. 1 ml was added.

In the culture solution after 24 hours, 48 hours, and 72 hours, the odor was completely eliminated from the test tube to which the biomagic bacterium was added.

On the other hand, in the test tube to which sterile water was added, the odor did not disappear.

in the ii) malodor prophylactic effect bio Velcro bacteria and bio Magic Powder bacteria are preincubated to 10 ³ U / ml or more and the above two media, the culture solution of from feather added in a 1: 1 ratio After 24 hours, 48 hours and 72 hours, the odor was examined.

 As a result, all samples were odorless.

Example 1 A 20% aqueous solution of biomagic powder was prepared, and feathers emitting bad odor were immersed in the aqueous solution and dried.

The odor has completely disappeared, even after one month.

Example 2 Ten pieces of magic tape having a size of 3 cm × 50 cm were placed in a futon using cotton as a filler emitting an unpleasant odor such as sweat. Examination of the smell 24 hours later revealed that the smell had almost disappeared, and one month later was the same.

Example 3 A 20% aqueous solution of biomagic powder was sprayed on the surface of a polyurethane foam of a health mat composed of a lower layer polyethylene foam and an upper layer polyurethane foam emitting an unpleasant odor such as sweat or polyurethane foam odor. After drying.

Almost no 24-hour-assisted unpleasant odor was observed, and it was the same one month later.

[Action / Effect]

As described above, according to the present invention, it is possible to eliminate the odor peculiar to animal fibers such as feathers, the odor of natural cotton and synthetic cotton, and the unpleasant odor peculiar to synthetic resins, and always keep the bedding clean. can do. Also, when using the bedding of the present invention,
An effect such as relieving the floor deviation is recognized, and it is also suitable as bedding for bedridden elderly and sick people.
