Embodiment 1

[0028] PLA resin slices enter the screw extruder for melt spinning, and go through the gradually heated extruder zone 1, extruder zone 2, extruder zone 3, extruder zone 4, extruder zone 5 and extrusion Melting in the six zones of the extruder (the temperature of the six zones of the extruder and the temperature of the extruder outlet are respectively set to 160°C, 165°C, 170°C, 175°C, 180°C, 185°C, 190°C), and then filtered The components intercept and filter the impurities in the slices, and finally the completely molten melt is sprayed out from the spinneret, and falls on the mesh delivery curtain of the melt-blown equipment 2 under the drafting of the high-speed hot air flow to form PLA melt-blown ultra-fine short fibers. Among them, the drawing temperature of the melt-blown hot air flow is 200°C, and the spinning speed is 600m / min; the cashmere is loosened on the conveyor net curtain added near the spinneret and sent to the roller 1 to be combed into a single fiber state, a...

Embodiment 2

[0031] PLA resin slices enter the screw extruder for melt spinning, and go through the gradually heated extruder zone 1, extruder zone 2, extruder zone 3, extruder zone 4, extruder zone 5 and extrusion Melt in the six zones of the extruder (the temperature of the six zones of the extruder and the temperature of the extruder outlet are set to 163°C, 168°C, 173°C, 178°C, 183°C, 188°C, 200°C respectively), and then filtered The components intercept and filter the impurities in the slices, and finally the completely molten melt is sprayed out from the spinneret, and falls on the mesh delivery curtain of the melt-blown equipment 2 under the drafting of the high-speed hot air flow to form PLA melt-blown ultra-fine short fibers. Among them, the drawing temperature of the melt-blown hot air flow is 230°C, and the spinning speed is 800m / min; the alpaca is loosened on the conveyor net curtain added near the spinneret and sent to the roller 1 to be combed into a single fiber state, and th...

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 nonwoven materials, and relates to a composite accompanying environmental protection imitation goose down thermal insulation material and a production method thereof. The thermal insulation material with goose down structure has a good effect of blocking air flow and good thermal insulation effect, and can be applied in various environments, especially suitable for traditional clothing. Background technique [0002] Traditional clothing, home textiles, footwear and other thermal insulation materials are always unsatisfactory in terms of the balance of warmth retention and comfort. There are various disadvantages of moisture absorption, easy mildew, easy hardening, easy allergy 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, requiring clothing...
