Kerugian utama serat polivinil alkohol adalah kemampuan pewarnaan yang buruk, jumlah pewarnaan yang rendah, dan warna yang tidak cerah. Ini karena serat memiliki struktur inti-kulit dan beberapa gugus hidroksil terhalang oleh asetalisasi. Selain itu, ketahanan air panas dari serat polivinil alkohol buruk, dan penyusutan serta deformasi yang jelas akan terjadi ketika suhu melebihi 110-115 \u00b0 C dalam keadaan basah. Kain serat polivinil alkohol akan larut sebagian setelah ditempatkan dalam air mendidih selama 3 hingga 4 jam. Selain itu, elastisitas serat polivinil alkohol tidak sebagus serat sintetis lainnya seperti poliester, dan kainnya tidak cukup kaku, serta rentan kusut selama pemakaian.<\/p>\n
