Problems solved by technology

[0004] In order to solve the problem that the existing flame-retardant polyester fiber flakes burn droplets when they encounter an open flame, the technical solution of the preparation method of the flame-retardant non-melting flakes of the present invention is to consider that the flame-retardant flakes do not melt during use. Development of characteristics of water washing

Embodiment 1

[0010] Main material: phosphorus-based flame-retardant polyester staple fiber and cotton. The weights are respectively: the weight ratio of phosphorus-based flame-retardant polyester staple fiber to cotton is 90:10. Mix the two main ingredients that have been weighed together and send them into the fiber blending machine. After 30 minutes of thorough mixing, it is sent to a fiber opener for fiber opening, and the fiber is blown and mixed by a blower and sent to a storage box. Get 1740g to make fiber flakes through carding machine carding, send to laying machine and spread into length 2.0m, the certain thickness high bulkiness flake of width 1.5m. Coat the outer surface of high bulk flakes with 30g / m 2 The thin spunlace non-woven fabric enters the needle loom together with the floc for needle punching. The needle-punched flakes are impregnated in a tank filled with a 3% concentration of polyphosphate amine solution, and the impregnation temperature is 35°C. After being roll...

Embodiment 2

[0013] The preparation process is the same as that of Example 1, except that the weight ratio of the main material phosphorus-based flame-retardant polyester staple fiber to cotton is 80:20. The difference is that 1440 g of fiber flakes are obtained by carding with a carding machine, and the needle-punched flakes are impregnated in a tank containing a 4% concentration of polyphosphate amine solution. Produced 500g / m 2 The finished product of flame retardant non-melting flakes.

[0014] The flake sample was sent to the testing center for testing. The test results showed that the combustion characteristics: carbonization; burning time: 9.65S; flame retardant time: 0; damage length: 109mm; standard.

Embodiment 3

[0016] The preparation process is the same as that of Example 1, except that the weight ratio of the main material phosphorus-based flame-retardant polyester staple fiber to viscose staple fiber is 70:30. The difference is that the needle-punched flakes are impregnated in the tank filled with 3.5% polyphosphate amine solution. Made length 2m; width 1m; 300g / m 2 The finished product of flame retardant non-melting flakes.

[0017] Inspection results of flake samples: combustion characteristics: carbonization; burning time: 8.65S; flame retardant time: 0;

Abstract

The present invention relates to a prepartion method of flame-retardant fibre flocculus. Its main raw material includes phosphorus series flame-relardand polyester staple fibre and cotton fibre or viscose staple fibre, and its preparation process includes the following steps: mixing fibres, opening, air-mixing, air-conveying, storing, carding, web-laying, covering, needling, impregnating, mangling and oven drying, said invention also provides the concrete requirements and concrete operation method of every step.

Description

technical field [0001] The invention relates to a method for preparing flame-retardant fiber flakes, in particular to a method for preparing flame-retardant fiber flakes obtained by blending and carding phosphorus-based flame-retardant polyester staple fibers and cotton fibers or viscose staple fibers. The flame-retardant fiber flakes prepared by the method have high-efficiency flame-retardant effects, and have the effect of not producing molten droplets when the fiber flakes burn. Background technique [0002] Fiber wadding is the hard insulation layer of bedding, and its structure is fluffy. It is the most flammable product in textiles, and it is also the most difficult to impart flame retardant properties. At present, there are flame-retardant flakes produced from flame-retardant polyester fibers on the market. Although this flake has a certain flame-retardant effect, it will produce a large amount of pasty high-temperature melt when it is burned in an open flame. This m...
