A novel conjugate fiber with a fine and an optical interference color-generating function, suitable for application in product fields which require aesthetic qualities, the fiber being characterized by having a structure wherein an alkali-soluble polymer with a thickness of 2.0 μm or greater surrounds an alternating laminated section with a thickness of no greater than 10 μm, comprising alkali-insoluble polymer layers with different refractive indices alternately laminated parallel to the long axis direction of the flat cross-section, wherein the ratio (SP1/SP2) between the solubility parameter value of the higher refractive index polymer (SP1) and the solubility parameter value of the lower refractive index polymer (SP2) is in the range of 0.8-1.1.

The invention belongs to the technical field of water-soluble polymer material, and in particular relates to a preparation method of a high-solid content polypropylene papermaking reinforcing agent. According to the method, raw materials such as acrylamide, crylic acid, ammonium persulfate and sodium sulfite are adopted to prepare a papermaking reinforcing agent through an aqueous solution polymerization technology, so that problems of low solid content and poor water solubility in the prior art are solved. By utilizing the preparation method, the polymer molecular weight and solid content are improved, the transportation cost and production cost are effectively lowered, and the obtained product has reinforcing, retension and dispersing effects and good dissolvability and can be completely dissolved in the water after soaking in the water, so that the utilization rate of the product is increased, and the product has a wide market prospect and an obvious economic benefit.
