Problems solved by technology

[0003] Although down and cashmere on the market can achieve a certain degree of warmth, the quantity is limited, the market price is high and the price is extremely unstable, and the processing technology is still very complicated. After the product is produced, it is too fluffy, which affects the appearance of the product (such as down jacket)
Although cotton and hemp are natural products, their warmth retention coefficient is low. When the weather is very cold, they cannot play a good heat preservation effect.
Although down has the advantages of lightness, softness, and fluffiness, it ha

Embodiment 1

[0029] 1: Open the hot-melt fiber and tencel fiber separately through the textile opener, and mix the two according to the weight ratio of 16:10;

[0030] 2: Then mix 90% down with the mixed fiber, the mixing ratio depends on the required content of the finished down product, after mixing, it is mixed evenly by a mixer and impurities such as fine feather rods are removed again, and it is called down mixed fiber;

[0031] 3: Flatten the above-mentioned down mixed fiber at the entrance of the cleaning machine and control its entering quantity to 60 kg / hour, and then sew it into a block with duck down thread;

[0032] 4: Carding the sewn lumpy down mixed fiber through the carding machine: the down, tencel fiber and hot-melt fiber can be evenly combined into a network structure, and it is not easy to break; and the blocky down is controlled The thickness of mixed fibers is between 0.3 mm and 0.5 mm;

[0033] In this step, the carding machine must be debugged and operated as follo...

Embodiment 2

[0037] 1: Open the hot-melt fiber and tencel fiber separately through the textile opener, and mix the two according to the weight ratio of 17:12;

[0038] 2: Then mix 90% down with the mixed fiber, the mixing ratio depends on the required content of the finished down, after mixing, it is mixed evenly by a mixer and impurities such as fine feather rods are removed again, and it is called down mixed fiber;

[0039] 3: Spread the above-mentioned down mixed fiber at the entrance of the cleaning machine and control its entering quantity to 70 kg / hour, and then sew it into a block with duck down thread;

[0040]4: Carding the sewn lumpy down mixed fibers through the carding machine: the down, tencel and hot-melt fibers can be evenly combined into a network structure, and it is not easy to break; and control the blocky down mixing The thickness of the fiber is between 0.3 mm and 0.5 mm;

Abstract

The invention relates to a compound thermal insulation material eiderdown flocculus taking eiderdown, mainly duck down and goose down as the main materials and the making process thereof. The compound thermal insulation material eiderdown flocculus is made by the eiderdown, mainly the duck down and the goose down as well as synthetic fabric, wherein the synthetic fabric is made by meldable fiber and tencel fiber in the weight ratio of 13 to 18:6-15; the mixing ratio of the eiderdown and the synthetic fabric is set by the contents required by the finished eiderdown product; and during making, the animal eiderdown is the main material and the meldable fiber and tencel fiber are the auxiliary materials, and the materials are made into the compound thermal insulation material with 65% content of eiderdown according to different ratios. The compound thermal insulation material eiderdown flocculus not only has the thermal insulation characteristic of the eiderdown and cashmere products, but also is environment-friendly, has spinnability and cuttability, rather lower cost, simple and mature process, easiness for operation and big market potential.

Description

technical field [0001] The invention relates to a natural down wadding flake of a composite heat-preserving material made of down mainly including duck down and goose down as main materials and a manufacturing process thereof. Background technique [0002] At present, thermal insulation materials can be divided into two types, natural fibers and artificial chemical fibers (commonly known as chemical fibers). Natural thermal insulation materials are mainly animal hair such as down, cashmere, camel hair, silk, etc., and plant fibers such as cotton and hemp. Artificial compounds are mainly based on oil and other extracts, such as silk cotton. [0003] Although down and cashmere on the market can achieve a certain warmth retention factor, the quantity is limited, the market price is high and extremely unstable, and the processing technology is still very complicated. After the product is produced, it is too fluffy, which affects the appearance of the product (such as down jacke...
