Description
Technical Field
The invention belongs to the technical field of functional textiles, and particularly relates to an aerogel light thermal fabric and a manufacturing method thereof.
Background
China is the largest textile producing country, export country and consumer country in the world, textile export plays an important role in foreign trade in China, and along with the gradual understanding of consumers in various countries on functional textiles, higher requirements are put forward on the functionality of the textiles.
With the increasing of extreme severe weather in recent years, people put forward higher requirements on the heat preservation performance of textiles, and meanwhile, more and more people pursue fashion and love sports, which requires that the heat preservation textiles of people cannot be too thick, heavy and clumsy.
Among the commonly used fiber materials, animal fibers such as cashmere, duck down, goose down and the like have the best warmth retention property, but the materials are obtained in a mode of being exposed to animals by animal protection tissues for many times, so that the use of the animal fibers is reduced by various well-known brands in the world.
Aerogel has relatively low thermal conductivity, and the application of aerogel to textiles to manufacture thermal fabrics has been reported in documents, however, in the existing method, mainly, aerogel particles are filled in the fabrics [ see documents 1 to 4 ]; there are also literature reports of adding aerogel insulation layers to fabrics [ see literature 5 ].
However, both of these methods have limited warmth retention property and cannot achieve lightweight property.

The fineness of the aerogel fiber prepared in the step S1 is 50D to 100D, preferably 75D.
The dyeing and finishing method in the step S3 is as follows:
s31: and soaking the woven fabric in a pretreatment liquid containing sodium carbonate and a refined emulsifier, and treating at the temperature of 80-98 ℃ for 15-40 min.
S32: and (5) performing acid neutralization on the fabric pretreated in the step S31 at the temperature of 20-40 ℃ for 5-20 min.
S33: and dyeing the fabric neutralized by the acid in the step S32.
S34: and (3) carrying out reduction cleaning on the fabric dyed in the step S33 at 80-90 ℃ for 20-30 min, then carrying out acid neutralization at 55-65 ℃ for 10-30 min, finally treating the fabric with crude oil at 20-30 ℃ for 15-20 min, and drying.
Because the aerogel fiber is fast in coloring and easy to color, the dyeing in the step S33 needs to be performed by adding a dye-philic leveling agent for 10-15 min, then adding a dispersing agent and a disperse dye, adjusting the pH value to 4-4.5 by using glacial acetic acid, and finally dyeing for 30-60 min at 120-140 ℃.
The aerogel light thermal fabric manufactured by any one of the methods.
As described aboveThe gram weight of the aerogel light super-warm fabric is less than or equal to 200g/m2。
The thickness of the aerogel light super-warm fabric is 3-5 mm.
The invention has the following positive effects: (1) according to the invention, the aerogel is added into the terylene to prepare aerogel fibers, and the aerogel fibers are directly used as yarns to be woven into the fabric, so that the fabric has high heat retention property and is relatively light. (2) The key technology of the invention is that a dye-philic leveling agent is added in advance during dyeing, so that the dyeing rate of dye can be reduced, and the problem of easy dyeing is avoided.
