Description

Quick-drying down filling material and preparation method thereof

The invention belongs to the field of down filling material processing, and specifically relates to a quick-drying down filling material and a preparation method thereof.

Down is a flower-like fluff that grows on the abdomen of geese and ducks, and the flakes are called feathers. Because down is a kind of animal protein fiber, the down ball-shaped fiber is densely covered with thousands of small triangular pores, which can shrink and expand with temperature changes, produce a temperature adjustment function, can absorb the flowing heat of the human body, and isolate the intrusion of cold air from the outside. . From the analysis of the bulkiness test, down is one grade higher than silk, cotton and other warm materials. For example, the minimum standard of 450 degrees fluffy 90 duck down is also better than silk and cotton. So down is simply used as a warm material. Its economic value is much higher than other warm materials.

In addition, natural down also has good moisture absorption and dispersion properties that other warm materials do not have. According to the measurement, the body constantly radiates sweat when sleeping. An adult can emit about 100 grams of sweat overnight. Down can continuously absorb and discharge the sweat released by humans, so that the body does not feel wet and stuffy.

To sum up, because of the unique soft warmth, moisture absorption and good performance of down, it has always been used as a high-quality natural filling material. However, due to the hygroscopicity of down, it is susceptible to being affected by humid environments, damaging its bulkiness and weakening its warmth retention performance.

In view of this, our inventors devoted themselves to further research, and proceeded to develop and improve, in the hope of a better design to solve the above problems, and after continuous experimentation and modification, the present invention came out.

The weight of the above down filling material is equal For 100g.

The quick-drying down filling materials obtained in Examples 1, 2 and 3 and ordinary down were soaked in cold water for 10 minutes. After being completely soaked, they were put into a dryer with a drying temperature of 120°C. Record the weight of the down every 2.5 minutes and calculate the moisture weight. The experimental results obtained are shown in [Table 1] and Figure 1.

[Table 1]: Change of moisture weight in down (g)

According to the data in the table, after averaging the data of the experimental group, curve fitting is performed to obtain Figure 1. It can be clearly seen from Figure 1 that the curve in the experimental group is significantly steeper than that in the control group. The drying time (15min) of the quick-drying down filling material is significantly shorter than the drying time (25min) of the control group, and the quick-drying down filling material obtained by the present invention can greatly reduce the drying time.

After washing the quick-drying down filling materials obtained in Examples 1-3 repeatedly for 10 times, the above drying experiment was repeated, and the results obtained are shown in [Table 2].

Compared with [Table 2], it can be concluded that the drying time of the quick-drying down filling material after washing is basically the same as that of the unwashed quick-drying down filling material. It can maintain good quick-drying characteristics.

Experimental example 2

This experimental example is divided into an experimental group and a control group. The experimental group is a quilt made of the quick-drying down filling material obtained in Example 3, and the control group is a quilt made of 90% white goose down without quick-drying treatment on the market. The specific operations are as follows:

Take 100g of quick-drying down and ordinary down and sew them into a 50*50cm quilt (2*2 grid). The quilt fabric is 60*60 cotton fabric. Put the two quilts into the household washing machine at the same time, using the standard mode Carry out washing, after washing, put it in the outdoor temperature of 40℃ for drying (Shenzhen, summer). After being touched and dried, you can accept it and record the drying time.

The results showed that the outer fabric of the quilt of the control group and the experimental group were completely dried in half an hour, while the down in the control group was completely dried in 1h45min, and the quick-drying down filling material in the experimental group was completely dried in 1h. It shows that the quick-drying down filling material can exert quick-drying performance in actual use and reduce the time of drying.
