As a result, 14 people expressed their impression that they felt smooth and gentle on the skin, such as “Wipe your wet hands with this PG-bonded fiber, leaving a smooth feel on your skin.” The remaining one expressed his impression that “I don't feel much”. From this result, it can be seen that the cotton fabric combined with proteoglycan has an excellent texture such as being gentle to the skin.
- Test Example 4 Durability Test The durability of the bound proteoglycan was examined by repeatedly washing the proteoglycan-bound fiber product.
- Proteglycan was bound in the same procedure as in Example 3 except that treatment with 0.1M sodium periodate was 30 minutes, treatment with 1% by weight proteoglycan was 4 hours, and treatment with 0.1M NaBH 4 was 4 hours.

- the texture test was tried about the cotton towel and cotton gauze towel which processed the above. As a result, the smooth feel of the cotton towel and cotton gauze towel was sufficiently retained even when the number of washing treatments was 5 and 10. From this, it is considered that the proteoglycan-bonded fiber product of the present invention has excellent durability because the proteoglycan is stably bound to the fiber even in washing with a washing machine.

実施例2で製造したプロテオグリカン結合ハンドタオルを家庭用洗濯機及び家庭用洗剤を用いて洗濯及び乾燥を繰り返した。洗濯及び乾燥作業の都度、洗濯前の肌触りと比較した風合いを評価した。結果を以下の表2に示す。
縦33cm、横33cmの綿タオル及び綿のTシャツを使用して、以下の手順にてプロテオグリカンが結合したタオル及びTシャツを製造した。
実施例3と同様の手順で0.1M NaIO4(過ヨウ素酸ナトリウム溶液)の処理時間を20分、30分、50分と変化させた。用いた繊維製品サンプルは33×33cmの綿タオル(合計30枚 )、23×23cmの綿タオル(合計30枚)及び綿ガーゼタオル(合計30枚)、木綿生地(さらし)、綿(わた)である。0.1M過ヨウ素酸ナトリウム溶液への浸漬は室温で50分とした。また、1重量%プロテオグリカン溶液での処理時間を4時間とし、0.1MNaBH4による還元時間も室温で4時間とした。いずれの繊維製品サンプルでも損傷は認められなかった。
0.1M過ヨウ素酸ナトリウム溶液での処理を30分とし、1重量%プロテオグリカンでの処理を4時間とし、0.1MNaBH4での処理を4時間とする以外は、実施例3に示す手順と同様にしてプロテオグリカンを結合した綿タオルを作製し、更にそれに以下の手順でプロテオグリカンを結合させた。
実施例3及び実施例4で得られた、各プロテオグリカン結合繊維製品について風合い試験を行った。無作為に成人15人を選び、ぬれた手をプロテオグリカン処理した綿布で拭いてもらった。その結果、14人が、「ぬれた手をこのPG結合繊維で拭うと、肌にスベスベした感触が残る。」など、スベスベしたいい感じ、皮膚に優しい感じ、との感想を述べた。残りの1名は、「あまり感じない」、との感想を述べた。この結果から、プロテオグリカンを結合した綿布は、肌に優しいなどの優れた風合いを有していることが分かる。
プロテオグリカン結合繊維製品を繰り返し洗濯することによって、結合したプロテオグリカンの耐久性を調べた。
