Production process and production equipment of aerogel glue-sprayed cotton thermal liner
Technical Field
The invention discloses a production process and production equipment of an aerogel glue-sprayed cotton thermal lining, and belongs to the technical field of garment accessory production equipment.
Background
The glue-spraying cotton is also called gunite cotton, which is a kind of non-woven fabric. The principle of the formation of the collodion spraying structure is that the adhesive is sprayed on both sides of the fluffy fiber layer, because of certain pressure during spraying and suction force during vacuum liquid absorption at the lower part, the adhesive can be infiltrated into the interior of the fiber layer, and the fiber layer after being sprayed with the adhesive is dried and cured, so that the junction points between fibers are bonded, and the fibers which are not bonded with each other still have a great degree of freedom.
The thermal insulation and fluffiness of the glue-sprayed cotton are due to the fact that a plurality of gaps containing air exist in the glue-sprayed cotton, so that the glue-sprayed cotton is widely used in the clothing industry, but in outdoor clothing such as outdoor jacket, due to the fact that the glue-sprayed cotton is often affected by cold wind in outdoor activities, the traditional glue-sprayed cotton has very limited thermal insulation effect, and the thermal insulation performance is poor when the cold wind penetrates through the clothing.
