Problems solved by technology

[0005] Natural down has good heat retention, but down is easy to get damp due to the humidity of the environment, improper storage is prone to mildew and mites, and its strength is poor, too much washing will make the down pulverized and clumped, reducing the warmth retention

Abstract

The invention discloses a method for producing down-like fiber, and relates to the technical field of textiles. The down-like fiber is formed by blending, melting and spinning polypropylene, polyether ester and far infrared anionic micro powder with the grain diameter of less than 30 nanometers. The method can spin the novel down-like fiber with health-care and environment-friendly function, high elasticity, high fluffy property, light weight and heat insulation. The down-like fiber can be applied to health-care and warm-keeping filling of down garments, quilts, sleeping bags and pillow inners and applied to decorative fabrics of spun yarns, non-woven fabrics and the like, and the environment-friendly and health-care function of the down-like fiber is favorable for human health and improvement of air quality.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to technical fields such as chemical fiber, melt spinning, warm-keeping clothing, non-woven decorative cloth, environmental protection, and health care. technical background [0002] As we all know, polypropylene fiber has thermal insulation, light weight (0.91g / cm 3 ) non-toxic, odorless, good skin-friendly, anti-mildew, anti-bacterial. The source of raw materials is wide and the price is low, so it should be an ideal warm-keeping material for clothing. However, according to years of research and development, even if polypropylene fiber forms a hollow three-dimensional helical crimp, its compression resilience and bulkiness are far inferior to polyester hollow three-dimensional helical crimp fiber. In polyester (1.38g / cm 3 ), its light weight and warm-keeping properties failed to bring into play. [0003] Polyetherester fiber is a highly elastic fiber with an elastic mechanism...
