Embodiment 1

[0072] see figure 1 – Figure 6 , a method for preparing bionic bird's nest cotton formed by airflow stacking, the preparation method includes sequentially performing an opening and mixing process, a stacking and forming process, a drying and cooling process, and a finished product removal process; the preparation method also includes an airflow conveying process, and the airflow The conveying process is located between the opening and mixing process and the stacking and forming process;

[0073] The opening and mixing process refers to: opening and mixing low-melting point polyester staple fibers and three-dimensional crimped hollow polyester staple fibers to obtain mixed fibers; the composition and weight ratio of the mixed fibers are: low melting point polyester staple fibers 20 –45, three-dimensional crimped hollow polyester staple fiber 55–80;

[0074] The air-flow conveying process refers to: use air-flow to convey the above-mentioned mixed fibers along the feed pipe 1...

Embodiment 2

[0079] Basic content is the same as embodiment 1, the difference is:

[0080] The molding die 2 includes an upper module 3 and a lower module 4 combined upper and lower, and the upper module 3 and the lower module 4 are provided with ventilation holes 22 .

Embodiment 3

[0082] Basic content is the same as embodiment 2, the difference is:

[0083] In the drying and cooling process, the drying operation refers to that hot air is introduced into the vent hole 22 of the upper module 3, and the hot air is discharged from the vent hole 22 of the lower module 4; The vent hole 22 of 3 leads into cold air, and by the vent hole 22 of lower module 4, cool air is discharged. The temperature of the hot air is 180°-230°, and the temperature of the cold air is room temperature.

Abstract

The invention discloses a preparation method of airflow piled formed bionic bird nest cotton. The preparation method comprises an opening and mixing working procedure, an airflow conveying working procedure, a piled forming working procedure, a drying and cooling working procedure and a finished product taking-out working procedure in sequence. In the airflow conveying working procedure, mixed fiber is conveyed through airflow to move forwards along a feeding pipe so as to enter an inner cavity of a forming mold; in the piled forming working procedure, under the effect of airflow, the inner cavity is continuously filled with the mixed fiber, conveying is not stopped until the inner cavity is full of the mixed fiber, and at the moment, the mixed fiber in the inner cavity is piled to form a workblank. When the workblank is dried or cooled, a unique ventilation process can be adopted to improve the drying or cooling ventilation uniformity. According to the design, the processing technological process can be shortened, the utilization rate of raw materials can be improved, meanwhile, the piled forming uniformity of the raw materials can be improved, the drying or cooling uniformity can be enhanced, and the heat retention property, breathability, elasticity and strength of the product can be improved.

Description

technical field [0001] The invention relates to a method for preparing bionic bird's nest cotton, which belongs to the field of nonwoven fabrics, and in particular to a method for preparing bionic bird's nest cotton formed by airflow stacking, which is particularly suitable for shortening the processing process and improving the utilization rate of raw materials. Background technique [0002] Fluffy material is a necessity in people's life, and can be used in furniture, sound-absorbing cotton for speakers, baby products, cushions, bedding products, bra cups, car interiors, sporting goods and other fields. According to the preparation method, bulky materials can usually be divided into four categories: sponge, warp-knitted spacer fabric, three-dimensional elastic woven fabric, and non-woven fabric. [0003] Sponge, a porous material, is a polyurethane foam material with light weight, soft and plump feel and good resilience. Due to its low price and large application volume, ...
