Isilika yePolyamide yenziwe ngefayibha yepolyamide, ifilament yenylon kunye nesilika emfutshane. Ifilament yenylon ingenziwa ibe yintambo eyoluliweyo, intambo emfutshane ingaxutywa nekotoni kunye nefayibha ye-acrylic ukuphucula amandla ayo kunye nokuguquguquka kwayo. Ukongeza ekusetyenzisweni kwayo kwiimpahla kunye nokuhombisa, ikwasetyenziswa kakhulu kwimiba yemizi-mveliso efana nentambo, ibhanti yokudlulisa, ipayipi, intambo, inethi yokuloba njalo njalo.
Ukumelana nokuguguleka kwe-nylon filament yazo zonke iintlobo zelaphu ekuqaleni, amaxesha amaninzi aphezulu kunezinye iifayibha zeemveliso ezifanayo, ngoko ke, ukuqina kwayo kugqwesile.
I-filament ye-nylon inokuguquguquka okugqwesileyo kunye nokubuyiselwa kwe-elastic, kodwa kulula ukuyitshintsha ngenxa yamandla amancinci angaphandle, ngoko ke ilaphu layo kulula ukulishwabanisa xa ligugile.
I-filament ye-nylon yilaphu elikhaphukhaphu, lilandela kuphela i-polypropylene kunye nelaphu le-acrylic phakathi kwamalaphu okwenziwa, ngoko ke lifanelekile kwiimpahla zokunyuka intaba kunye neempahla zasebusika.
