Production process of thermal fabric

The invention discloses a production process of a warm-keeping fabric, belongs to the technical field of fabrics, and optimizes the defect of poor washing resistance of phase change microcapsules of a hollow fiber phase change temperature adjusting fabric prepared by a hollow fiber filling method in the production process of the warm-keeping fabric. In the production process, the water-based fluorocarbon resin modified phase change microcapsule is placed in the middle cavity of the kapok, the water-based fluorocarbon resin can be attached to the surface of a wall material polyurea when being added into the phase change microcapsule, the surface energy of the polyurea is reduced, the surface tension of the polyurea is improved, and therefore the phase change microcapsule is endowed with hydrophobic performance; the hollow fiber phase-change temperature-adjusting fiber phase-change microcapsules are added, the washing durability of the hollow fiber phase-change temperature-adjusting fiber phase-change microcaps
