Problems solved by technology

[0003] With the continuous development of textile technology, the performance of polyester has gradually been improved, and its comfort and warmth have also been improved compared with before. At present, there are also a variety of flame-retardant polyester staple fibers. The flame-retardant properties of polyester fibers are mainly It is endowed by flame retardants, but most of the flame-retardant polyester staple fibers with better performance in domestic use still rely on imports. There are two main ways to impart flame-retardant properties. One is to align them during polyester polymerization. Modification to obtain flame retardancy, but this method is complicated in process, high in cost, and requires a lot of manpower and material resources for research and development; one is to reprocess the fiber in the later stage to endow it with flame retardancy, but this method has flame retardancy The lifespan is short, and its flame retardancy will gradually weaken or even lose after being used for a period of time, and the warmth retention and comfort of polyester fibers treated according to this method will be affected to a certain extent

Abstract

The invention relates to a flame-retardant and heat insulation composite fiber fill and a manufacturing method thereof, and belongs to the technical field of garment fills. The manufacturing method of the flame-retardant and heat insulation composite fiber fill comprises the following steps of preprocessing raw materials; 2, manufacturing a melt-blowing non-woven fabric; 3, conducting opening; 4, conducting carding; 5, laying meshes and spraying adhesives; 6, spraying adhesives to the back face. Immersion treatment is performed on hollow fine staple PET fiber, the excellent fire retardancy and heat insulation performance are achieved, and due to the steps of vacuum drying, opening, carding and the like, the flame-retardant and heat insulation composite fiber fill has the good touch and comfort; meanwhile, the melt-blowing non-woven fabric and the hollow fine staple PET fiber are combined, the fire retardancy and the heat insulation performance of the obtained fill are further enhanced, the obtained fill has the excellent filtering performance and the heat insulation performance, and heat losses can be effectively avoided.

Description

technical field [0001] The invention belongs to the technical field of clothing fillers, and in particular relates to a flame-retardant and heat-retaining composite fiber filler and a manufacturing method thereof. Background technique [0002] Polyester staple fiber, that is, polyester staple fiber, is a short fiber obtained by spinning polyester into tow and cutting it. The general polyester staple fiber is 4D-22D, which can be divided into two-dimensional and three-dimensional according to its crimp. According to textile requirements, polyester staple fiber and polyester filament can be manufactured. Polyester has good wear resistance and water absorption, and its wear resistance is second only to nylon among synthetic fibers, and it has good insulation. It is mainly used in the cotton textile industry, and can be spun alone or combined with cotton , linen, wool and other blends can be used for filling and thermal insulation materials. [0003] With the continuous develo...
