In order to solve the above-mentioned problems in the field of hygiene products, especially in paper diapers, ES fiber provides a multifunctional ES fiber that can effectively prevent diaper rash. The functional spinning oil is 20-25% by weight of antistatic agent, 15- 20% weight emulsifier, 6% polyacid silicone oil, 0.2% antibacterial agent, 2% antibacterial synergist, 2% acid regulator, the epidermis is made of PE, and the outer layer is cathodic Composition or PP composition, the thickness of the fiber is 1.5-handle, and the length is 30-60mm. In the multi-functional spinning oil, the existing ES fiber spinning oil usually adopts b (hydrophilic-lipophilic balance value) as 9~ Surfactant 15 is used as a hydrophilic component and has good hydrophilicity, but its surface energy is quite different from that of ES fiber cortex PE, and its adsorption is poor. It dissolves quickly when it meets water, and achieves hydrophilicity many times.
The polysiloxane oil in the multi-functional spinning oil, after the es fiber meets water, the polyacid end quickly turns to the water interface. At the same time, the surface energy of the hydrophobic end Si-C is similar to that of the ES fiber cortex PE. The Si-O-Si bonding angle of the chain segment is large, the bonding is long, and it is very easy to rotate. The force between polysiloxane molecular chains is small, which can be firmly adsorbed on the surface of ES fibers, and can be washed, effectively realizing the multiple affinity of fibers. watery. Here, the degree of polymerization of the hydrophobic terminal siloxane and the amount of propane addition number in the side chain polyacid are directly proportional to its adsorption and inversely proportional to its hydrophilicity; The degree of polymerization of the hydrophobic end-capped siloxane of polysilicone oil and the addition number of propane and ethylene oxide in the side-chain polyacid, the number of addition of ethylene oxide in the side-chain polyacid is inversely proportional to the adsorption property, and is inversely proportional to the adsorption property. The hydrophilicity is directly proportional, so that its adsorption and hydrophilicity reach an ideal balance level. In addition, according to the special structure of the above-mentioned polysilicone oil, applying it to the fiber spinning oil can make the manufactured ES fiber and its non-woven fabric have good softness and sliding properties.
