Product Description 

 

 

DHK291 is a super soft & excellent stable textile softener.  It is comprised of revolutionary silicone molecules to deliver voluminous and silky hand feels to fabric. It provides hydrophilicity to most types of textile fiber or fabric at lower use level than other silicone softeners.  It is very stable in ordinary textile finish process without causing oil spots.

 DHK291 has quaternary function group that can enhance superior affinity and durability to most types of textiles compared to conventional hydrophilic and amino silicone softeners.

DHK291  is able not only to spread on the fiber surface to deliver unusually full and rich hand-feels, but also to deeply penetrate  into the interior of natural fibers to modify each single fiber & make the fabric premium.

 DHK291 is a concentrate softener that can be diluted to any grades. As it is  water-dispersible & pourable, it can be straightly used in textile mills by padding and exhaustion that require outstanding shear stability to avoid finish process trouble such as oil spotting on fabrics.
