Junning urchuqsimon panjalari
Veretenoobraznыe kletki shersti

Junning urchuqsimon panjalari- jun tolasining yirik molekulyar qobiq ustidagi oxiri uchlik bo‘lgan holalalr bo‘lib (ularning uzunligi – 90 mkm), ko‘ndalang o‘lchami 2…6mkm, ayrim hollarda 10mkm gacha bo‘ladi. Ko‘ndalang fibrilli tutamchalardan, ular o‘z navbatida, keratin makromolekulalaridan iborat. Korteks deb atalishi, tolaning o‘rtacha po‘tsloqli qatlamni shakllantiradi.

Veretenoobraznыe kletki shersti - krupnыe nadmolekulyarnыe obrazovaniya s zaostrennыmi konsami (ix dlina - do 90 mkm), imeyuщie razmer poperechnika 2...6 mkm, inogda do 10 mkm. Sostoyat iz prodolnыx puchkov fibrill, kotorыe, v svoyu ochered, sostoyat iz makromolekul keratina. Formiruyut sredniy korkovыy sloy volokna, tak nazыvaemыy korteks.

Spindle-shaped cells of the hair are large supramolecular formations with pointed ends (their length is up to 90 microns), having a diameter of 2 ... 6 microns, sometimes up to 10 microns. They consist of longitudinal bundles of fibrils, which, in turn, consist of keratin macromolecules. Form the middle cortical layer of the fiber, the so-called Cortex.

Vlagootdacha

Namlikni chiqarilishi- material sirtidan namlikni atrof muhitga bug‘lanishi, uni quritish jarayonining asosiy qismi. Havoning 1000 va 0% nisbiy namligida ushlangan material massasini materialning havoni nisbiy namlikda saqlangandan keyingi massasi bilan quritilgandan keyingi o‘zgarmas massasiga nisbati bo‘yicha hisoblanadi.

Vlagootdacha - isparenie vlagi s poverxnosti materiala v okrujayuщuyu sredu, sostavnaya chast protsessa ego sushki. Rasschitыvaetsya kak otnoshenie raznitsы mejdu massoy materiala posle vыderjivaniya pri otnositelnoy vlajnosti vozduxa 100% i 0% k raznitse mejdu massoy materiala posle vыderjivaniya pri otnositelnoy vlajnosti vozduxa 100% i postoyannoy massoy materiala posle vыsushivaniya

Moisture - the evaporation of moisture from the surface of the material into the environment, an integral part of the process of drying. Calculated as the ratio of the difference between the mass of the material after keeping at a relative humidity of 100% and 0% to the difference between the mass of the material after keeping at a relative humidity of 100% and a constant weight of the material after drying
