Neylon va PP to'quv o'rtasidagi farq: Umuman olganda, neylon to'quv birinchi navbatda to'qiladi va keyin bo'yaladi, shuning uchun kesishdan keyin ipning rangi notekis bo'yash tufayli oq rangga aylanadi, PP to'quv avval bo'yalgan va keyin to'qilgan, shuning uchun u to'qilgan bo'lmaydi. Ip oq bo'lgan hodisa mavjud; farqli o'laroq, neylon to'r PP to'ridan ko'ra porloq va yumshoqroq; yonishning kimyoviy reaktsiyasi bilan ham ajralib turishi mumkin; neylon to'rning narxi odatda PP to'quvidan yuqori.
