Abstract
The invention discloses a heat-resistant non-woven fabric. The fabric is characterized by comprising a non-woven fabric base layer and a heat-resistant layer, wherein the heat-resistant layer comprises an upper layer and a lower layer, the non-woven fabric base layer is located between the upper layer and the lower layer, the non-woven fabric base layer is compounded and connected with the heat-resistant layer through a heat adhesive, the upper layer is formed by heat adhesion of polyimide fibers, and the lower layer is formed by heat adhesion of polyphenylene sulfide fibers. With the adoption of the method, the heat-resistant non-woven fabric is unchanged in size at the high temperature, high in thermal decomposition temperature, good in softness and processability and applicable to various high-temperature-resistant clothes and other materials.
Description
Technical field
The present invention relates to nonwoven fabric, particularly relate to a kind of heat-resistant nonwovens.
Background technology
High temperature resistant nonwoven fabric refers to the nonwoven fabric that can use for a long time under more than 180 ° temperature conditions, the physical and mechanical property possessing in the time of maintaining normal temperature under this high temperature or still have MIN physical and mechanical property through longer service time.
Nonwoven fabric is environment-friendly materials of new generation, has the features such as the water of refusing, ventilative, pliable and tough, not combustion-supporting, nontoxic nonirritant, rich color, and along with the development of the sophisticated technologies such as national defense industry, high temperature resistant nonwoven fabric is being brought into play more and more important effect.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of heat-resistant nonwovens, and at high temperature size is unchanged, and heat decomposition temperature is high, and flexibility and processing characteristics good, be applicable to doing various high temperature resistant clothes and other materials.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of heat-resistant nonwovens is provided, comprise nonwoven fabric basic unit and refractory layer, described refractory layer comprises the upper and lower, described nonwoven fabric basic unit is between the upper and lower, described nonwoven fabric basic unit and refractory layer are by hot sticky glue composite joint, and described upper strata is formed by polyimide fiber heat bonding, and described lower floor is formed by polyphenylene sulfide fibre heat bonding.
In preferred embodiments of the present invention, degree of crystallinity more than described polyimide fiber 30wt% is 30%～45%.
In preferred embodiments of the present invention, the diameter of described polyimide fiber is 1～35um.
In preferred embodiments of the present invention, described upper thickness is 0.5～0.8mm.
In preferred embodiments of the present invention, degree of crystallinity more than described polyphenylene sulfide fibre 40wt% is 35%～55%.
In preferred embodiments of the present invention, described polyphenylene sulfide fibre diameter is 0.3～4mm.
In preferred embodiments of the present invention, described lower thickness is 0.3～0.5mm.
In preferred embodiments of the present invention, in described heat-resistant non-woven fabric, the shrinkage factor under 185 ° of conditions is below 4.5%, tensile strength 0.35 (N/cm)/(g/m of weight per unit area
2) more than.
Beneficial effect of the present invention: a kind of heat-resistant nonwovens is provided, and at high temperature size is unchanged, and heat decomposition temperature is high, and flexibility and processing characteristics good, be applicable to doing various high temperature resistant clothes and other materials.
