\u00c7in'in Han Hanedanl\u0131\u011f\u0131 d\u00f6neminde ya\u015fam\u0131\u015f bir devlet adam\u0131 olan Cai Lun, 105 y\u0131l\u0131nda k\u00e2\u011f\u0131d\u0131 icat etmi\u015f ve k\u00e2\u011f\u0131t yap\u0131m teknolojisini m\u00fckemmelle\u015ftirmi\u015ftir. Bu icattan \u00f6nce ka\u011f\u0131t kenevir ve ipek liflerinden yap\u0131l\u0131yordu, ancak Cai Lun ka\u011f\u0131t yapmak i\u00e7in biraz farkl\u0131 malzemeler kulland\u0131. Devlet adam\u0131n\u0131n icat etti\u011fi k\u00e2\u011f\u0131t dut ve kenevir liflerine dayan\u0131yordu ve \u00fcretiminde k\u00fcl kullan\u0131l\u0131yordu. <\/p>\n
<\/p>\n
Cai Lun'un ilk k\u00e2\u011f\u0131d\u0131 dut ve kenevir lifleri, pa\u00e7avra ve k\u00fcl kullan\u0131larak yap\u0131lm\u0131\u015ft\u0131, ancak mucit daha sonra k\u00e2\u011f\u0131d\u0131 daha g\u00fc\u00e7l\u00fc, p\u00fcr\u00fczs\u00fcz ve uygulanabilir hale getirmek i\u00e7in ni\u015fasta, bitkisel boyalar, kire\u00e7 ta\u015f\u0131 ve di\u011fer malzemeleri kulland\u0131. <\/p>\n
Tsai Lun y\u00f6ntemini kullanarak ad\u0131m ad\u0131m ka\u011f\u0131t yap\u0131m\u0131: <\/p>\n
[INDENT]- Elastikiyet kazand\u0131rmak i\u00e7in elyaf ve di\u011fer kaba malzemelerin \u0131slat\u0131lmas\u0131;
\n- Liflerin odun k\u00f6m\u00fcr\u00fc ile \u0131s\u0131l i\u015fleme tabi tutulmas\u0131, liflerin \u00f6\u011f\u00fct\u00fclmesi. T\u00fcm bu ad\u0131mlar sel\u00fcloz olu\u015fumuyla sonu\u00e7lanm\u0131\u015ft\u0131r;

Bu sayede yaz\u0131 yazmaya uygun, g\u00fc\u00e7l\u00fc ve esnek bir ka\u011f\u0131t \u00fcretilebildi. Cai Lun 25 ya\u015f\u0131ndan itibaren imparatorluk saray\u0131nda g\u00f6rev yapt\u0131. Eski yaz\u0131lar bize imparatorun ast\u0131n\u0131n ba\u015far\u0131s\u0131ndan o kadar memnun oldu\u011funu s\u00f6yler ki, Cai Lun'a aristokrat bir unvan bile vermi\u015f ve ona yeni yetkiler tan\u0131m\u0131\u015ft\u0131r. Mucit ayr\u0131ca imparatordan kendisini zengin ve sayg\u0131n bir adam yapan bir miktar para ald\u0131. <\/p>\n
Ancak ka\u011f\u0131t mucidinin ba\u015far\u0131s\u0131, Cai Lun'u b\u00fcy\u00fck bir entrikan\u0131n i\u00e7ine \u00e7eken di\u011fer saray mensuplar\u0131 taraf\u0131ndan engellenemedi. Cai Lun'un ad\u0131 karaland\u0131 ve bask\u0131lara dayanamayarak \u00f6l\u00fcmc\u00fcl bir zehir i\u00e7ti. Cai Lun, 50 y\u0131l\u0131nda do\u011fdu ve hayat\u0131n\u0131n 55. y\u0131l\u0131nda b\u00fcy\u00fck bulu\u015funu ger\u00e7ekle\u015ftirdi. Ka\u011f\u0131d\u0131n mucidi ya\u015fam\u0131n\u0131n 71. y\u0131l\u0131nda (121 ya\u015f\u0131nda) \u00f6ld\u00fc. <\/p>\n
K\u0131sa s\u00fcre sonra \u00c7in, \u00fcretimin t\u00fcm s\u0131rlar\u0131n\u0131 dikkatle saklayan ka\u011f\u0131t ustalar\u0131yla zenginle\u015fti. Yedinci y\u00fczy\u0131l\u0131n ba\u015flar\u0131nda Kore ve Japonya'da Cai Lun k\u00e2\u011f\u0131t yap\u0131m y\u00f6ntemi kullan\u0131lmaya ba\u015flanm\u0131\u015f, ard\u0131ndan k\u00e2\u011f\u0131t yap\u0131m\u0131n\u0131n s\u0131rlar\u0131 di\u011fer Asya \u00fclkelerindeki ustalar taraf\u0131ndan da bilinir hale gelmi\u015ftir. Bat\u0131'da ka\u011f\u0131t yap\u0131m\u0131n\u0131n s\u0131rlar\u0131, Araplar\u0131n sekizinci y\u00fczy\u0131lda Semerkant kentinde \u00c7inli ustalardan birini ele ge\u00e7irip ondan t\u00fcm teknolojiyi ve ka\u011f\u0131t tabakalar\u0131n\u0131n \u00fcretimini \u00f6\u011frenmelerinden sonra ortaya \u00e7\u0131kt\u0131. <\/p>\n
Ancak Avrupa'da modern ka\u011f\u0131t on ikinci y\u00fczy\u0131la kadar \u00fcretilmedi - Avrupal\u0131lar Tsai Lun'un icad\u0131n\u0131 \u0131srarla g\u00f6rmezden geldiler. Cai Lun'un ad\u0131 bug\u00fcn hala pek \u00e7ok Avrupa kitab\u0131nda ve referans kitaplar\u0131nda yer almamaktad\u0131r. \u00c7in'de okula giden her \u00e7ocuk ilk k\u00e2\u011f\u0131d\u0131 yapan Cai Lun'un icad\u0131n\u0131 ve kaderini bilir.<\/p>","protected":false},"excerpt":{"rendered":"
