Ioyile yokwenziwa kwePhospholipid
Ioyile yokwenziwa kwePhospholipid, kwicandelo lokucubungula iikhemikhali zesikhumba, kufuneka ibhekwe ngokuchanekileyo njenge-synthetic phospholipid emulsifier. Yinto ekumgangatho ophezulu kwii-emulsifier zesikhumba zanamhlanje ezidibanisa iimpawu zendalo kunye neempawu zokwenziwa. Yenziwa ngokutshintsha okanye ukuxuba ii-phospholipid zendalo (ezifana ne-soy lecithin) kunye nezinto zokwenziwa (ezifana nee-phosphates zokwenziwa, izithambisi zokwenziwa). Injongo yayo kukunika ulusu ubuthambile obugqithisileyo, ukuthungwa kwevelvet ekhethekileyo, kunye nefuthe elihle lokuzalisa.

Uhlobo lokwenziwa olutshintshiweyo ...
Iiarhente zokutshintsha umbala ezifakelweyo zezohlobo oluthile lokutshintsha umbala zezona ziphambili kusapho lweearhente zokutshintsha umbala ezifakelweyo kwaye zibizwa ngokuba “zizalisa iiarhente zokutshintsha umbala ezifakelweyo”. Ngokungafaniyo neearhente zokutshintsha umbala ezifakelweyo (ezisebenza kakhulu ekusasazeni nasekudibaniseni umbala) ezineziphumo zokusasazeka kunye nokulinganisa, iiarhente zokutshintsha umbala ezifakelweyo zohlobo oluthile zokutshintsha umbala ngokwazo zinamandla amakhulu okutshintsha umbala kwaye zinokuthatha indawo yenxalenye okanye uninzi lweearhente zokutshintsha umbala ezifakelweyo (kautu) kwi-leather shinning. Kwangaxeshanye, zinokunika ulusu ukumelana nokukhanya okungcono, ukuthamba kunye neempawu zokuzalisa.

I-Amino resin
I-Amino resin tanning agent "yingcali yokubumba" kwinkqubo yokuguqula umbala wesikhumba. Ngokuzalisa okukhethiweyo okugqwesileyo, isebenza ngokuchanekileyo kwiindawo ezithambileyo ezifana nemiphetho kunye nemithungo yesikhumba, inciphisa ngempumelelo umahluko wenxalenye kwaye isombulule ingxaki yomphezulu okhululekileyo. Kwangaxeshanye, inika ulusu uvakalelo olukhethekileyo lokugcwala, ukuqina kunye nokuthamba. Ukuba i-acrylic tanning agent inoxanduva "lokuzalisa nokuthambisa", i-synthetic tanning agent inoxanduva "lokulungisa ngokubanzi", ngoko ke i-amino resin tanning agent "kukwakha okuqinileyo kunye nokuzalisa okukhethayo".
