MAQOLA ANNOTATSIYASI

Tabiiy ipak mahsulotlari o‘zining gigiуenik xususiyatlari bilan ularga bo‘lgan talabni yuqoriligi bilan ajralib turadi. To‘qimachilik matolarni bo‘yashda bir tekis ravon ranglarni hosil qilishda turli iflosliklardan (tabiiy, shuningdek yigirish, to‘qish jarayonlarida ishlatiladigin silikon yog‘lar, moylar va boshqalar) tayyorlash jarayonini jadal olib borish orqali gidrofob iflosliklardan tozalashni taqazo etadi. Shuning uchun tabiiy ipakni bo‘yash uchun tayyorlash dolzarb masala hisoblanadi. Tabiiy ipakning asosiy tola hosil qiluvchi komponenti - fibroinning kimyoviy reagentlar ta'siriga sezgirligi tufayli pardozlash operatsiyalarini (xususan, уelimsizlantirish) yumshoq sharoitlarda amalga oshirilishi kerak, shuningdek tolani mustaxkamligiga ta’sir etmagan holda bu kimyoviy moddalardan maksimal darajada foydalanishni talab etadi. Tabiiy ipakni qaynatishning ma'lum usuli (sirt faol moddalar asosidagi sovunli- sodali usul) tolani distruksiyasiga olib kelishi munkin. SHuning uchun ipakni уelimsizlantirish jarayonida biologik katalizatorlar –fermentlarni (enzimlar) qo‘llash ustida ishlar olib borilmoqda. Enzimlar bilan to‘qimachilik matolariga ishlov berish texnologiyalari an'anaviy tayyorlash va pardozlash texnologiyalariga alternativ texnologiya bo‘lib, ulardan foydalanish yumshoqroq, ekologik toza kimyoviy texnologik jarayonlarni yaratish kabi muhim muammolarni hal qilishga yordam beradi. SHuning uchun mazkur ilmiy izlanishlar yangi tabiiy ipakni уelimsizlantirishning fermentativ usulini qo‘llash imkoniyatlarini o‘rganishga bag‘ishlangan bo‘lib, tolani maksimal darajada shikastlamagan holdatayyorlash jarayonini effektivligini oshirishga bag‘ishlangan. Tanlab olingan usullar orqali fibroin strukturasini saqlagan holda ipak sirinsinidan maksimal darajada tozalash uchun neytral ta'sirga ega ferment Протосубтилин Г3х. ishtirokidagi tarkib va texnologik rejim tanlab olindi. Olib borilgan ishlar natijasida tavsiya etilayotgan qaynatishning fermentativ usuli orqali ipak matolarini faol bo‘yovchi moddalar bilan bo‘yashda bzyalgan matolarning rang intensivligi an'anaviy usulga nisbatan yuqoriligi aniqlandi.
