Each fabric needs to be treated with specific product before printing to obtain a specific penetration of the inks, avoiding image smudging.\nA high-performance anti-migrating agent for the preparation of textile goods like our Mirox P- Ink (or Mirox CFP in case of pigment inks) allows to obtain a high definition of the printing with same depth and brightness on the whole fabric width, avoids the dyes migration during the drying, doesn’t affect the handfeel, improves the stability of the padding baths by increasing the viscosity and prevents residues formations on the guide rollers in the drying room. Finally, it is easily and completely removed from fabric by rinsing.\n\nThe second phase of pre-treatment consists in providing stability to the dyestuff, especially on cellulosic fibers (rayon viscose and cotton), by prevent the hydrolysis of the reactive inks through an anti-reducing agent like our Isopal GL powder: prevents undesired color changes due to steam, high temperatures and prolonged operation times and also acts as oxidizing agent, stable in strongly alkaline conditions, obtaining a regular oxidation of reducing dyes without over-oxidation.\n\nIn the end, if the printed fabric has been pre-treated, the drying time is reduced and the fixation process is more efficient.\n\nPost-TREATMENT\n\nTo obtain very good fastness and brilliance, we need to remove unfixed dyestuff with specific auxiliaries like soaping, dispersing and fixing agents.\n\nISOPON HDS PLUS is our highly biodegradable specific low foam washing-off agent for printed goods, very effective in the removal of unfixed reactive dyes, even in presence of hard water; it allows a shorter post-treatment, unaltering the shades fastness and their brightness.\nIn case of polyester fibres, ISOPON SPO is our dispersing agent for PES reduction\nclearing step that improves the dyeing fastness prevents oligomers staining \u002F depositing.\n\nLast but not least, we need to properly fix the color by padding. \nOur FISSAT DFI improves the color yield and the crocking fastness values (wet and dry), and doesn’t affect the light fastness.\n\nAll our products for digital printing have an outstanding environmental profile and are approved by the most relevant certification bodies.\n",seo:{description:"Digital printing is way more flexible and cost-saving than traditional printing: it allows print-on-demand, minimizing waste and by-products, and allows a faster introduction of new designs\u002Fpatterns, without the need for cylinders or flat screens.\nThe production time is considerably shorter, resulting in energy and water savings.\n\nThe environmental impact of digitally printed textiles and garments is remarkably reduced.",title:U,_type:x},showIndex:r},{_rev:"0lbiuCz9ttW7FYEm5EWQHV",__i18n_refs:[{_key:_,lang:B,ref:{_weak:r,_ref:_,_type:g}}],_createdAt:"2021-07-23T10:13:22Z",_updatedAt:"2021-10-19T10:34:45Z",showIndex:r,categories:[{title:q,_id:J,slug:{current:p,_type:d},parent:f},{title:D,_id:E,slug:{current:F,_type:d},parent:{_type:h,slug:{current:o,_type:d},title:n}},{title:"Finishing ",_id:"d414cf9d-b8d1-487c-af18-c0f8fb5d96bc",slug:{_type:d,current:"finishing"},parent:{_type:h,slug:{current:o,_type:d},title:n}},{title:"Concrete",_id:"084206ff-9456-442b-aa24-8e8298d0f354",slug:{_type:d,current:"concrete"},parent:{_type:h,slug:{current:$,_type:d},title:aa}},{title:"Plasterboard",_id:"e776e33b-84d5-44f0-b4c6-4e14e5f4319c",slug:{current:"plasterboard",_type:d},parent:{_type:h,slug:{current:$,_type:d},title:aa}},{title:v,_id:t,slug:{current:u,_type:d},parent:{_type:h,slug:{current:p,_type:d},title:q}}],slug:{current:"formaldehyde-issue",_type:d},_id:"72e31f21-4013-4ba0-b9af-eeccf86ca835",content:[{_type:k,index:y,_key:"fa68c862a2fe",title:"Let’s make things clear",content:[{style:c,_key:"8cb4e3f0f1fe",markDefs:[],children:[{_type:a,marks:[e],text:"Formaldehyde is a biological compound generally occurring in nature",_key:"19d5bdee1365"},{_type:a,marks:[],text:": it is naturally produced by all living organisms.
