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

[0026] 1: Open the hot-melt fiber and polyester staple fiber separately through a textile opener, and mix the two according to the weight ratio of 16:10;

[0027] 3: 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;

[0028] 4: Flatten the above-mentioned down mixed fiber at the entrance of the light flower machine and control its entering quantity to 60 kg / hour, and then sew it into a block with duck down thread;

[0029] 5: Then remove impurities from the sewn down blended fiber by carding machine (mainly to remove the small feather rods remaining in the down) and control its thickness between 0.3 mm and 0.5 mm;

[0030] 6: Laying the feather silk mixed fiber layer by layer through the net-laying machine, the number of overlapping laying depends on the thickness requirem...

Embodiment 2

[0033] 1: Open the hot-melt fiber and polyester staple fiber separately through the textile opener, and mix the two according to the weight ratio of 17:12;

[0034] 3: Then mix 90% down with the mixed fiber, the mixing ratio depends on the required content of the finished down. After mixing, mix it evenly with a mixer and remove impurities such as fine feather rods again. It is called down mixed fiber;

[0035] 4: Spread the above-mentioned down mixed fiber at the entrance of the light flower machine and control its entering quantity to 70 kg / hour, and then sew it into a block with duck down thread;

[0036] 5: Then remove impurities from the sewn down blended fiber by carding machine (mainly to remove the small feather rods remaining in the down) and control its thickness between 0.3 mm and 0.5 mm;

Abstract

The invention relates to a natural down flocculus made of composite thermal insulation materials, which is made through taking down mainly comprising duck down and goose down as a main material, as well as a manufacturing process of the natural down flocculus. The natural down flocculus made of the composite thermal insulation materials is made of blend fiber and down mainly comprising duck down and goose down, wherein the blend fiber is formed by blending meldable fibers and polyester staple fibers according to weight ratio of (13-18):(6-15); and the blended ratio of the down and the blend fiber is determined according to the requirement of a down product. In manufacturing, animal down serves as a main material while the meldable fibers and the polyester staple fibers serve as auxiliary materials; and the composite thermal insulation material with the down content of above 65% is produced according to different ratios of all materials. The down flocculus has a good thermal insulation property like a down product or a cashmere product, is green and environment-friendly, and also has spinnability and tailorability. The process is relatively low in cost, concise and mature in process and easy to operate, and has a great 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...
