The device comprises a first salt powder bin (1), a first ejector (2), a first nozzle set (3), a second nozzle set (4), a second salt powder bin (5), a second ejector (6), a third nozzle set (7), multiple steam nozzles(8), a temperature control chamber (9) and multiple first pressing rollers (10) and second pressing rollers (13), wherein the first salt powder bin (1) is located above the first ejector (2), the first ejector (2) is connected with the first nozzle set (3) and the second nozzle set (4) separately, the second salt powder bin (5) is located above the second ejector (6), the second ejector (6) is connected with the third nozzle set (7), and the first pressing rollers (10) are horizontally placed in the temperature control chamber (9), and press second to-be-pressed fiber fabric (12) after beingpulled outwards through an external pulling mechanism (14).

Description

technical field [0001] The invention belongs to the technical field of chemical fiber coating equipment, and in particular relates to a device and a coating method for coating salt powder on fabrics. Background technique [0002] The fabric is a flat and soft piece made of textile fibers, which is composed of small and long objects crossed, knotted, and connected. A fabric is formed when many yarns form a stable relationship. Crossing, knotting and linking are three stable structural relationships that yarns can form. Make the fabric maintain a stable shape and specific mechanical properties. [0003] Among the prior art, there are various bonding methods used to apply salt powder on fiber fabrics or other fabrics, which are mainly divided into two categories: chemical methods and physical methods. In the field of chemical methods, it is common to use adhesives to apply salt powder to fabrics or other fabrics and bond them. [0004] There are usually two methods of coati...

AI Technical Summary

Problems solved by technology

[0004] There are usually two methods of coating and spinning addition. The former method mainly uses a special solution to configure special particles into dyes, which can be directly printed or coated on the surface of textiles according to needs. Generally speaking, fuels with relatively strong The viscosity or cross-linking characteristics of the coating can be achieved relatively easily, but due to this characteristic, the printing surface or coating surface is easy to form a layered airtight structure

Especially for sodium chloride, due to the instability of the recrystallization process, the air permeability of the coated surface is also very poor

[0005] The second method is spinning technology, which generally requires sodium chloride particle size to be smaller than micron, which greatly increases the cost of raw material production (the production cost of micron or submicron powder is ten times higher than that of 20-50 microns) above)

Moreover, due to the chemical characteristics of sodium chloride itself, it is difficult to find a suitable spinning solution for making

[0006] In practice, there are many types of fabrics, and their properties are also diverse. The existing methods use chemical methods to take time and difficult follow-up operations. In the existing methods, there is no physical method to apply salt powder to fiber fabrics or other fabrics.
