Embodiment 1

[0152] Prepared for special military uniforms, windbreakers and other thin glue-sprayed flakes, with a weight of 100g / m2.

[0153] The fiber weight ratio is: 50% of mixed polymer fiber (A) of aromatic polyamide and polyaryl sulfone, 25% of wool, 20% of nylon, and 5% of flame-retardant polyester with a melting point of 110°C.

[0154] The four kinds of fibers are evenly opened on the opener, sent to the large bin mixing box through the airflow, transported to the coarse opening and loosening box through the corner nail curtain, and then transported to the fine opening and loosening box, and then enter the cotton storage box. Then it is transported to the double-cylinder double-doffer carding machine through the mesh conveying curtain. In order to ensure that the physical properties of the spray-bonded cotton are consistent in all directions, the carded fiber web needs to be laid by the web-laying machine to the required thickness.

[0155] After the fiber web is output from the...

Embodiment 2

[0159] Prepare medium-thick flakes for electric welding clothes, etc., with a weight of 400g / m2.

[0160] The fiber weight ratio is: 40% of mixed polymer fiber (A) of aromatic polyamide and polyarylsulfone, 33% of fox fur, 20% of flame-retardant polyester, and 7% of flame-retardant polyester with a melting point of 110°C.

[0161] The four kinds of fibers are evenly opened on the opener, sent to the large bin mixing box through the airflow, transported to the coarse opening and loosening box through the corner nail curtain, and then transported to the fine opening and loosening box, and then enter the cotton storage box. Then it is transported to the double cylinder and double doffer carding machine through the mesh conveyor curtain. In order to ensure that the physical properties of the flakes are consistent in all directions, the carded fiber web needs to be laid by the web layering machine to the required thickness.

[0162] After the fiber web is output from the laminating...

Embodiment 3

[0166] Prepare thick glue-sprayed layered structure flakes for forest fire prevention and heat insulation clothing in Daxing'anling area, with a gram weight of 400g / m2.

[0167] The fiber weight ratio is: 45% aramid and polyaryl sulfone mixed polymer fiber (A), 25% rabbit fur, 25% flame retardant viscose, 5% melting point is 120 ℃ low melting point flame retardant polyester

[0168] 1) Preparation of fiber web AD: 45 parts of mixed polymer fiber (A) of aromatic polyamide and polyaryl sulfone and 2.5 parts of low-melting flame-retardant polyester are evenly mixed and opened, and sent to the large warehouse mixing box by air flow, It is transported to the coarse opening and loosening box through the corner nail curtain, and then transported to the fine opening and loosening box, and then enters the cotton storage box. It is transported to the double-cylinder double-doffer carding machine through the mesh curtain. In order to ensure that the physical properties of the sprayed co...

Abstract

The invention relates to high temperature resistant anti-flaming heat-insulation flocculus made of mixed polymer fiber containing aromatic polyamide and polyarylsulfone and a preparation method thereof. The flocculus comprises the mixed polymer fiber (A) containing aromatic polyamide and polyarylsulfone, heat-insulation fiber (B), anti-flaming fiber (C) and low melting point bonding fiber (D). The mixed polymer fiber (A) containing aromatic polyamide and polyarylsulfone is a blend fiber on the basis of the aromatic polyamide and polyarylsulfone and comprises 40 to 98wt% of aromatic polyamide and 2 to 60wt% of polyarylsulfone in a mixed manner. The flocculus has fine high temperature resistance, anti-flaming effect and washing resistance, the elasticity and the heat insulation performance of the flocculus are guaranteed after washing, and the flocculus can serve as a filler of heat insulation uniforms for personnel of electric power, gas stations, coal mines, forest fires, flammable and explosive chemical enterprises on the cold condition.

Description

technical field [0001] The invention relates to a high-temperature-resistant, flame-retardant, heat-insulating and warm-keeping flake of mixed polymer fiber comprising aromatic polyamide and polyarylsulfone and a preparation method thereof. Background technique [0002] In special operation industries in winter or in cold areas, such as electric power, chemical, coal mines, gas stations and other flammable and explosive workplaces, as well as ground operations, operators need to wear high-temperature-resistant and flame-retardant clothing with thermal performance when working . At present, except that the outer fabric of these workers is equipped with flame-retardant fabrics, the thermal insulation materials that can keep warm and keep out the cold are mostly polyester spray-bonded cotton, down and other materials. The above materials can keep warm and keep out the cold, but there is no Flame retardant function, once the ambient temperature is too high, these ordinary heat ...
