Abstract
The invention discloses a kind of polyimide nonwoven fabrics from color changing method, includes the following steps: fabric → processing → drying → colour examining；Wherein, the processing: treatment formulations and condition are as follows: soda ash: 5-7g/L；Sodium hydrosulfite: 10-30g/L；Handle the time are as follows: 10min-15min；Treatment temperature are as follows: 80 DEG C -90 DEG C.The present invention uses polyimide nonwoven fabric, carries out reduction treatment under alkaline condition, and color is shoaled green by golden yellow, and light green color is fixed up, and no longer aoxidizes in air.With the increase of reducing agent dosage, green deepens the present invention.The present invention makes polyimides become green without dyestuff, can produce the manufactured goods such as allochroic clothes, toy, home textile.
Description
Technical field
The invention belongs to textile industry fabric fields, and in particular to a kind of polyimide nonwoven fabric from color changing method.
Background technique
Polyimide fiber (Polyimide Fiber, abbreviation PI fiber).Polyimide fiber is otherwise known as fragrant acid imide
Fiber refers in strand containing the imido fiber of virtue.With the development of polyimides technology itself, synthetic technology is also continuous
Development, the cost of the expansion that synthetic technology is applied in other field, polyimides also reduces.The each technology department of national economy
The development of door, urgently gets up to the needs of the fiber of higher performance.But the included golden yellow of polyimide fiber itself, at present
Original liquid coloring produces limited several colors in spinning process, greatly constrains the application of fiber, and polyamides is sub-
The glass transition temperature of amine reaches to be spent more 300, and dyeing is very difficult.It is fine that existing patent of invention invention is related to a kind of polyimides
The method for tieing up disperse dyeing, comprising: (1) polyimide fiber is put into the solution of degreaser composition, bath raio 1:70~
120, it handles 50~70 minutes, is put into after cleaning in 2~40g/L lye at 50~70 DEG C, bath raio is 1:70~120,70~
90 DEG C are handled 5~15 minutes, then washing drying；(2) at room temperature, the polyimide fiber that step (1) obtains is put into work
In liquid, 120~150 DEG C are warming up to, keeps the temperature 30~60min, then cools to 60 DEG C, washing.The invention dyeing temperature will reach
It 135 degree or more, has higher requirements to device of high-temperature and high-pressure dyeing, is easy to happen explosion, mass production has certain limitation.
Summary of the invention
Goal of the invention: in order to solve the deficiencies in the prior art, the present invention provides a kind of becoming certainly for polyimide nonwoven fabric
Color method.
Technical solution: a kind of polyimide nonwoven fabric from color changing method, include the following steps: fabric → processing → drying
→ colour examining；Wherein, the processing: treatment formulations and condition are as follows: soda ash: 5-7g/L；Sodium hydrosulfite: 10-30g/L；When processing
Between are as follows: 10min-15min；Treatment temperature are as follows: 80 DEG C -90 DEG C.
As further optimization: the specification of the fabric is as follows: 100% polyimides nonwoven fabric is used, square
Mick weight is 120-140g/m2, color is golden yellow.
As further optimization: polyimide nonwoven fabric the drying: being carried out hot-air seasoning, the temperature of drying
Are as follows: 100 DEG C -102 DEG C；The time of drying are as follows: 8min-10min is 10-12% containing damp rate.
The utility model has the advantages that specific advantage of the invention is as follows:
1, the present invention uses polyimide nonwoven fabric, carries out reduction treatment under alkaline condition, color is shoaled by golden yellow
Green, and light green color is fixed up, and no longer aoxidizes in air.
2, with the increase of reducing agent dosage, green deepens the present invention.
3, the present invention makes polyimides become green without dyestuff, can produce the manufactured goods such as allochroic clothes, toy, home textile.
