Main characteristics of CRABYON
a. The CRABYON underwear, which 11 testees wore during the clinical test, is made of 30% CRABYON / 70% cotton fabric. Treatment and sewing were done by the process now commercially available on the market.

The test period of January to March, 1996, was dry and cold when people were susceptible to cold, so we must admit that the time was rather unfavorable for us to determine whether the underwear served to alleviate the symptom of atopic dermatitis.
All 11 testees were selected from among those who have relatively stable, slight to less symptomes to atopic dermatitis and who can see the doctor regularly.

b. Among the 11 testees, there was one testee whose symptom subsided considerably, one testee whose skin conditions improved, four testees whose skin conditions improved and two testees whose symptoms of atopic dermatitis could not be evaluated accurately because (1) one of them developed the sympto, of ashtma, being in bad physical condition, (2) one of them changed medicines, making it difficult to determine the effectiveness of the CRABYON underwear and (3) a mother who was too conscious of her child's atopic dermatitis overdosed her child, hoping it might improve the skin condition.
Even after considering the existence of such a mother, more than half of the 11 testees somewhat improved in skin conditions and one testee improved considerably; we think that the underwear is effective in improving the patients of atopic dermatitis.

c. All the CRABYON underwear used in clinical tests was dyed with fluorescent dyes and made with conventional sewing process. Some of the 11 testees parents said that, since the CRABYON underwear was soft to the skin even after repeated washings, they were able to use it without any worry.

Test of plant disease-resistance

Test method
Moistened cucumber seeds were planted on rock wool bed, bark block bed, CRABYON-non-woven fabric bed in a glass-house.
After two weeks plant disease bacteria, Phytophorame Langeae, was inoculated into cucumbers and resistance was checked one week after inoculation.

As is shown in the photograph, CRABYON bed proved to be more resistant to the disease than other beds.

The biodegradability of CRABYON

So long as CRABYON is made of organic material. Chitin/Chitosan and cellulose, its biodegradability is excellent. It begins to be decomposed by bacteria 2 weeks to 2 months after being buried underground, which is almost the same as in the case of natural fallen leaves.
