Manufacture process for composite heat insulation material

Abstract

The invention relates to a manufacture process for a composite heat insulation material, which has the steps that: 1, feather is firstly washed by water, sterilized, dried and loosened, and then, feather stems and feather silks are separated; 2, meldable fibers and polyester staple fibers are loosened and are mixed according to a weight ratio of 16 to 19 / 10 to 15; 3, the processed feather silks and the fibers mixed in the second step are mixed and are uniformly mixed through a stirring machine, and in addition, some impurities are removed; 4, the feather silk mixed fibers are sewed into blocky materials by duck down threads via a patterning machine; 5, then, the sewed feather silk mixed fibers are processed into thin sheets with the thickness being 0.3mm to 0.5mm through a carding machine, and the impurities are removed for a second time; 6, the feather silk mixed fibers are overlapped and paved layer by layer by a net paving machine; and 7, the feather silk mixed fibers are baked by an infrared baking oven, the baking temperature is set to 100 DEG C to 140 DEG C, and in addition, the cutting treatment is carried out, so the initial product breadth maintains the constant value. The composite heat insulation material has good heat insulation performance, the environment is protected, the spinnability and the shearing performance are realized, the price is relatively low, the raw material resources are rich, and the market demand potential is huge.

Description

technical field [0001] The invention relates to a manufacturing process of a composite heat-preserving material made of animal feathers (mainly ducks and geese) with feather rods removed as main materials. 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 products such as cotton and hemp on the market are natural products, their warmth retention coefficient is low, and when the weather is very cold, they cannot play a good heat preservation effect. Although natural products such as down and cashmere can achieve a certain degree of warmth retention, they are limited in quantity and the proces...

AI Technical Summary

Problems solved by technology

[0003] Cotton, hemp and other products currently on the market are natural products, but their thermal insulation coefficient is low. When the weather is very cold, they cannot play a good thermal insulation effect.

Although natural products such as down and cashmere can achieve a certain degree of warmth retention, they are limited in quantity and the processing technology is still very complicated. After the products are produced, they are too fluffy, which affects the appearance of the products, such as down jackets, etc., and their market prices are often high. extremely unstable

Feather is an agricultural and sideline product and is the best thermal insulation material in the world. It has the advantages of lightness, softness, and fluffiness. However, feathers have always been used as fillers for clothing and bedding. The style is limited and it is very inconvenient to wash

Moreover, there will be more or less feather odor left on the down, and sometimes it will reveal an uncomfortable odor.

[0004] Although artificial synthetic fibers are low in price, they also have low thermal insulation coefficient and poor thermal insulation effect, and most of them are chemical products, so it is difficult to avoid chemical pollution in the production process
