HT Fine Textile Chemical Auxiliary Agent

1. Strengthen the pre-treatment, especially the process of boil-out bleaching Using a mild non-caustic oxygen bleaching process(such as oxygen bleach accelerator + H2O2) to avoid the  wet rubbing fastness  affected by fiber brittleness, the rough surface of the fabric and the large friction coefficient of the fabric yarn surface in the process of oxygen bleaching. Strict control of water hardness to prevent the formation of surface lakes, causing the rough feel of the dye, increasing the friction coefficient and decreasing the wet rubbing fastness. The chelating agent, Ca2 +, Mg2 + and other metal ions can be added in the water to decrease the wet rubbing fastness. 2. Fabric can not be boiled with alkali soap after dyeing. Whether use mixed alkali fixation or single Na2CO3 fixation, the fabric must be fully washed with acetic acid 1 ~ 2mL / L in order to achieve fully hydrolysis of flooding, otherwise it will affect the effect of soap washing. 3. Control the quality of soap bo...

1.Dye-fixing agent theory. The basic principle is the covering theory, fixing agent is polymer, containing many sulfonic group with nylon fiber end amino bonded, forming a net structure, coated with dye, the color fastness to washing can be guaranteed and improve. 2.Dye-fixing condition In general, dye-fixing agent is as follows: Temp：70-80 ℃ PH：4.0-4.5 Time：20-30 min. Both the higher and lower temperature have negative influence on the dye-fixing effect. When the temperature is too low, the  dye fixing agent  can not be absorbed completely. When the temperature is too high, the dye-fixing agent penetrate too much to the inner of fiber and the covering effect will affected.  So  both of them will effect the result. 3.The reason for nylon color fixing spot The  dyeing Nylon  color fixing spot usually be caused by the following reasons: (1)the excessive hardness (Ca++, Mg++)of water (2)the weak cationic auxiliary residue on the fabric (3)the influence of aci...

【Recommendation】Enke non-formaldehyde dye fixative agent BRIFIX AKS BASE Product brief introduction  It is compounded by quaternary ammonium compound, and have excellent fasting effect. And it can be used to in the color fastening process of activated dyeing, dyeing and printing. Application scope 1. The color fastness process of dyeing cotton, rayon fabric and woven fabric with reactive dyes  2.The color fastness process of dyeing cotton, rayon fabric and woven fabric with direct dyes  Product property 1. Non-formaldehyde, environment friendly 2. The low rate of color change and yellowing in the process of dye-fixing.  3. Do not affect the original fabric hand-feeling and hydrophilic 4. For activated and direct dye, the fastness to washing will be up to 4 grades even 4-5 grades. 5. It has the advantages of wide temperature range. In the process of drying and shaping under temperature 100-170 ℃, it has excellent color fixation effect. The fixing way  1.the mol...

Dyeing and finishing tips│the production of dye-fixing agent Y and application ( The application of auxiliary and development ) Guiding There are different defects on the dye used in the textile industry. For example, the reactive dye lacks of deeper color types, and it is easy to hydrolyze. Which will cause shallow color dyeing and no resistance to chlorine bleaching. After dyeing process, it will be faded when washing. It has bad wet fastness, so we need to do dye-fixing. The types of dye-fixing agent is varied.  Dye fixing agent  Y is brief structural but practical. The dye-fixing agent mainly applied in the acid dye printing or dyeing as fastness agent. When it is used to deal with cotton, silk, human-made cottons, it will enhance the water washing and soap washing fastness. In the process of yarn-dyed fabric warp sizing, using this product will prevent from penetrating and stick colors. Fastness agent Y also used in color lake making and the fastness of paper ...
