Abstract

The invention relates to a preparation method of a spinning new material and specifically relates to a preparation method of a composite elastic fiber. The preparation method provided by the invention comprises the following steps: 1) selecting polyolefin elastomer masterbatch, thermoplastic resin, silicone rubber, a radiation sensitizer and an antioxidant, mixing according to a certain proportion, sending into a twin-screw extruder, and performing extrusion and dicing to prepare polyolefin mixed masterbatch; 2) sending the polyolefin mixed masterbatch into a hopper of a melt spinning machine, spraying out by a spinning jet, cooling by a side air-blowing corridor, and winding onto a bobbin by a winding device to obtain nascent composite elastic fiber; 3) placing the prepared nascent composite elastic fiber under a radiation environment for treatment at the radiation dose of 50-500kGy to prepare the composite elastic fiber. The composite elastic fiber prepared by the method provided by the invention has the advantages of good mechanical properties, elastic elongation and elastic recovery ratio, and can be used for producing products with various specifications according to process adjustment so as to meet the development of various types of fabric.

Description

technical field [0001] The invention relates to a preparation method of a new textile material, in particular to a preparation method of a composite elastic fiber. Background technique [0002] With the rapid development of China's economy and the continuous improvement of people's living standards, people who love fashion feel oppressed by the busyness and competition in the city. Comfort is demanded. In order to meet the comfort of fabrics, designers choose elastic fibers, so the demand for elastic fibers has been in a strong growth stage in recent years. [0003] At present, the types of elastic fibers commonly used are relatively single, and they are only used in sportswear and underwear, which cannot meet people's diverse needs for elastic clothing fabrics. In recent years, scientists have been committed to developing a variety of elastic fibers to meet clothing for various occasions. fabric needs. Contents of the invention [0004] The technical problem to be solv...
