NEOLEVE SDX-D, EMILL NW-1570, QUEENFIX NPU-01
(1) | preventing spandex from staining during dyeing. |
(2) | avoiding redeposition of dyes during washing are important. |
Polyester/spandex blends recommended recipe
(1) | Adding Neoleve SDX-D (staining inhibitor) during dyeing prevents disperse dye staining(adsorption) on spandex, and helps its further distribution into polyester. |
(2) | Emill NW-1570 (reduction clearing agent) used in reduction clearing further washes off disperse dyes stains on spandex, leading to good reproducibility and colorfastness (including for washing, dry-cleaning and staining of test liquor). |
(3) | When uneven dyeing occurs because of the high blended rate of spandex, adding 1~2g/L of Newsurf MF-10 (special scouring agent) to the dye bath eliminates the trouble of uneven dyeing of polyester/spandex by emulsifying/dispersing and solubilizing silicone oil attached to spandex. |
Nylon/spandex blends recommended recipe
(1) | Adding Neoleve SDX-D (staining inhibitor) during dyeing forcefully prevents acid dye staining on spandex. |
(2) | Emill NW-1570 (reduction clearing agent) used in soaping further washes off acid dye stains on spandex and prevents redeposition. |
(3) | By using Queenfix NPU-01 (fixing agent) in fixing, excellent fastness can be achieved without color alternation and dullness. Fastness can be improved significantly compared to conventional synthetic tannin type nylon fixing agents. |
(4) | Depending on the type of leveling agent, scum may occur during treatment with QueenfixNPU-01 (fixing agent). In this case, 0.3~0.5g/L of Preventer S (Anti-scum agent for nylon) can be added in the fixing bath or the type of leveling agent can be changed. |
(5) | When uneven dyeing occurs because of the high blended rate of spandex, adding 1~2g/L of Newsurf MF-10 (special scouring agent) to the dye bath eliminates the trouble of uneven dyeing of nylon/spandex by emulsifying/dispersing and solubilizing silicone oil attached to spandex. |
