Application of low-foaming FMEE end-capped with PO in wool-scouring agent.

The fatty acid methyl ester ethoxide (FMEE) has excellent emulsifying property for animal fat and clearing power of protein fouling. The introduction of PO group into the structure of FMEE can not only reduce the foaminess of FMEE, but also increase lubrication force of FMEE. In the wool washing process, FMEE with PO ends can form a lubricating film on the surface of wool scales, which can reduce the wool intertwine with each other. Using FMEE in PO block as the main component, the conditioner 6501, solvent ethylene glycol tert-butyl ether and osmotic agent sodium primary alkyl sulfonate were mixed to obtain a cleaning, felt-proof and balanced performance wool washing agent. The proportion of FMEE in PO block, conditioning agent 6501, ethylene glycol tert-butyl ether and sodium primary alkyl sulfonate was determined to be 3:2:1 to produce wool washing agent. It can not only remove the grease, protein fouling and metal soap deposited on the surface of wool, but also effectively protect the original elasticity, strength, color and other properties of wool, so that the washed wool is white and loose without felting.
