In the case of white cocoon, the fluorescence colorf are classified as a yellowish fluorescence cocoon (Y.F.C.) and a violet fluorescence cocoon (V.F.C.) by exposing to ultra·violet ray. Accordingly, experiments were carried out to investigate the difference of seriein behaviors between Y.F.C. and V.F.C. by measuring the sericin solubility, surface tension and viscosity of the sericin solution. Also, the reelability of two different type of cocoons was investigated in the silk reeling process. The results were summarized as follows; 1. The sericin solubility of Y.F.C. shell is higher than that of V.F.C. shell with the dissolution trmperature and time. It is shown that the seriein solubility curves of Y.F.C. and V.F.C. are similar in shape, but the difference of sericin solubility between Y.F.C. and V.F.C. is more significant at higher bath temperature. 2. The initial seriein dissolution curves of Y.F.C. and V.F.C. cocoon shell can be devided by four parts within the range of dissolving time from 5 minutes to 60 minutes. The initial dissolution velocity of Y.F.C. shell is faster than that of V.F.C. but the velocity difference is negligible after 30 minutes of dissolving time. 3. The gelation of V.F.C. seriein solution is faster than that of Y.F.C. at early stage(in the range of 15 minutes to 60 minutes). 4. In the silk reeling process, the realability of Y.F.C. is better than that of V.F.C. with about 11%. This is mainly due to the higher sericin solubility in Y.F.C. followed by the fast dissolution velocity.

The web of Atypus coreanus KIM, 30mg had been collected to analyze Chemical properties in Yangsu-ri(Yangpyong-gun) Kyunggi-do, Korea. This is web that was made into purse web. In the result of this quantitative analysis, the web has about the most 14.68% Alanine in 17 amino acids.

Spiders are easily distinguished from all other creatures by behavior of making webs. Among the web building spiders which depend largely on their webs to predation, Atypidae, four species in Korea, uses the purse web which is the most primitive one than other spider`s web in Korea. To analyze the chemical properties of the purse web, 30 ㎎ of Atypus coreanus` web was collected in Joan-myun, Namyangjoo-city, Kyunggi-do. As a result, the purse web of Atypus coreanus mostly consists of Glycine (5.3%), Glutamic acid (8. 26%) and Alanine (14. 17%). Especially the web of Atypus coreanus has more proportion of serine (9.28%), which plays an important role in intricacy, than that of orb webs used by Nephila clavata(4.84%) and Araneus ventricosus(4.84%).
