The invention discloses a blending type clothing lining elastic foaming material which comprises a TDI group and an MDI group which are blended, and the mass ratio of the TDI group to the MDI group is 20:(6.5-12); the TDI group comprises the following components in parts by mass: 1000 parts of isocyanate TDI, 100-120 parts of polyether, 2-5 parts of ethylene glycol, 3-5 parts of phenol and 1-2 parts of polysiloxane copolymer, and the isomer ratio of 2, 4-TDI to 2, 6TDI of the isocyanate TDI is 100:(25-35); and the MDI group comprises the following components in parts by mass: 1000 parts of diphenylmethane diisocyanate, 30-35 parts of polyether, 2-5 parts of ethylene glycol, 2-3 parts of phenol, 5-6 parts of silicone oil and 2-3 parts of dichloromethane. The material has the characteristics of high resilience and high elastic recovery degree, is soft and comfortable in contact, has TDI characteristics and MDI characteristics, is washable and anti-deformation, and can prolong the service life of clothes. A blending foaming process is performed after the TDI group and the MDI group are respectively foamed, so that the requirement of fiber uniformity is met, the stable and reliable quality of the elastic foaming material is ensured, the raw material cost of the foaming material is reduced, and the market competitiveness is relatively high.
