saw fade results of red-weft denim from an overseas brand on social media and found the evolution so interesting that we decide to develop our own version.This dyeing process replaces the white cotton yarn with red yarn,achieving a \"red-core\"fading effect.The red portion uses reactive dye for high color fastness,so as the indigo wears off with use,the underlying red is gradually revealed instead of white.We bagan trails in May this year,went through multiple sampling stages,and have only recently finalized the product for release.While the dyeing theory is straightforward-simply changing the yarn color while keeping the indigo dyeing process unchanged-for a brand with over a decade of experience in raw denim,we still encountered various challenges in production,which slowed down our progress.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp style=\"text-align: left;\"\u003e\u003cspan style=\"color: rgb(0, 0, 0);\"\u003e\u003cimg

reactive dyeing process,subsequent indigo dyeing contaminates the indigo dye vats.Since indigo dyeing requires multiple layers and numerous vats,the contaminated vats and leftover dye must be discarded and thoroughly cleaned after each dyeing cycle.This requires reserving the entire production line of the dyeing mill,and upon completion of one fabric batch,all remaining dye is wasted and vats must be cleaned-resulting in extremely high dyeing costs.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cspan style=\"color: rgb(200, 57,

not as simple as dyeing ordinary fabric.The red yarn core must not be fully penetrated by dye,while the indigo must be applied deeply and repeatedly only on the surface,keeping the red portion clean.Multiple trials resulted in the red yarn being oversaturated and discolored,which would prevent the red from showing through during fading.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cspan style=\"color: rgb(200, 57, 14);\"\u003e\u003cstrong\u003eFabric Challenge 3:\u003c\/strong\u003e\u003c\/span\u003eThis was something we never anticipated:repeated dyeing may alter the toughness and twist strength of the yarn.During weaving on vintage shuttle looms,the proportion of defects increased significantly.While minor imperfections are common and acceptable in old-loom selvedge denim,we discard more severe flaws and only retain those that are slight.However,this red-core fabric exhibited an unusually high defect rate,leading to hundreds of meters being scrapped out of several thousand meters woven-dramatically increasing costs.We will address this issue in future production runs,and these losses will not be passes on to consumers through pricing.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cimg
