Embodiment 1

[0028] PLA resin chips enter the screw extruder for melt-spinning, and go through the extruder zone one, extruder zone two, extruder zone three, extruder zone four, extruder zone five and extruder respectively. Melt in the six zones of the machine (the temperature of the six zones of the extruder and the temperature of the extruder outlet are set to 160℃, 165℃, 170℃, 175℃, 180℃, 185℃, 190℃), and then filtered The components intercept and filter the impurities in the slices, and finally the completely melted melt is ejected from the spinneret, and is drawn by the high-speed hot air stream to form PLA melt-blown ultra-fine short fibers on the mesh curtain of the melt-blown equipment 2. Among them, the melt-blown hot air drafting temperature is 200℃, and the spinning speed is 600m / min; the cashmere is opened on the increased conveyor screen near the spinneret and sent to the roller 1 to be carded into a single fiber state, and the speed is 2000r / min roller 1 throws the carded fib...

Abstract

The invention discloses a composite accompanying environment-friendly imitation goose down thermal material and a method for producing the same.The composite accompanying environment-friendly imitation goose down thermal material is prepared from PLA (polylactic acid) melt-blown superfine short fibers and a type or a plurality of types of cashmere, camel hair, alpaca wool and rabbit hair fibers.The surface density of the composite accompanying environment-friendly imitation goose down thermal material is 50-300 g/m<2>, the thickness of the composite accompanying environment-friendly imitation goose down thermal material is 3-30 mm, a CLO value of the composite accompanying environment-friendly imitation goose down thermal material is 0.8-3, the warmth retention rate of the composite accompanying environment-friendly imitation goose down thermal material is 50-85%, and a thermal resistance value R of the composite accompanying environment-friendly imitation goose down thermal material is 0.5-3.The composite accompanying environment-friendly imitation goose down thermal material and the method have the advantages that shortcomings of bulkiness, easiness in deformation due to water washing, down piercing and the like of the traditional down feather can be effectively overcome; existing melt-blowing equipment is modified, so that the light, thin, environment-friendly and efficient imitation goose down thermal material can be developed and is wide in service range, and development of the thermal material industry can be effectively promoted.

Description

Technical field [0001] The invention belongs to the field of non-woven materials, and relates to a composite associated environmental protection goose down thermal insulation material and a production method thereof. The thermal insulation material with the goose down structure has a good effect of blocking air flow and good thermal insulation effect. It can be used in various environments and is especially suitable for traditional clothing. Background technique [0002] Traditional thermal insulation materials such as clothing, home textiles, and footwear are always unsatisfactory in terms of the balance of warmth and comfort. There are various shortcomings such as moisture absorption, mildew, hardening, allergies and poor hand feeling. With the improvement of people's living standards, people not only require clothing to meet the traditional cold protection function, but also pay more attention to the decorative beauty of clothing. They require clothing that is novel in style,...
