Problems solved by technology

Currently commonly used fabric flame retardants include inorganic flame retardants, organophosphorus and organic nitrogen flame retardants, inorganic flame retardants mainly include red phosphorus, ammonium polyphosphate, aluminum hydroxide, magnesium hydroxide, etc., such flame retardants Usually, the flame retardant effect can only be exerted when the amount of addition is large, and the compatibility with the fabric is poor, and the mechanical properties of the fabric will be affected if the amount of addition is too large; organophosphorus flame retardants mainly include phosphate esters, organophosphorus Salt, phosphorus and nitrogen compounds, etc., but poor heat resistance and poor compatibility with fabrics; organic nitrogen flame retardants have good thermal stability, but the flame retardant effect is not ideal

Embodiment 1

[0035] Processing of spunlace nonwovens:

[0036] (1) Pulping: first utilize the hydraulic pulper to pulverize the bamboo fiber, and then utilize the refiner and the refiner to refine the pulp to obtain the bamboo fiber slurry;

[0037] (2) Filtration and impurity removal: the prepared bamboo fiber slurry is diluted with water to a mass concentration of 1%, and sent into a slurry tank through a screw pump, and then sent to the impurity removal process through a slurry pump once, using sand removal Filter and pressure sieve to remove impurities, and then sent to high-speed mixer through screw pump;

[0038] (3) flame retardant modification: add flame retardant modifier to the bamboo fiber slurry after filtering and removing impurities, the consumption of flame retardant modifier is 0.5% of bamboo fiber dry weight, and be heated up to 50-55 ℃ high-speed Mix for 10 minutes at a speed of 650 rpm, then continue to heat up to 75-80°C and mix at high speed for 5 minutes at a speed o...

Description

Technical field: [0001] The invention relates to the technical field of spunlace nonwoven fabric processing, in particular to a processing technology of flame-retardant plant fiber spunlace nonwoven fabric. Background technique: [0002] Spunlaced non-woven fabric is a fabric obtained by spraying high-pressure fine water onto one or more layers of fiber webs to entangle the fibers with each other, so that the fiber webs can be reinforced and have a certain strength. The fiber raw materials of spunlace non-woven fabrics come from a wide range of sources, such as polyester, nylon, polypropylene, viscose fiber, chitin fiber, microfiber, tencel, silk, bamboo fiber, wood pulp fiber, seaweed fiber, etc. [0003] The spunlace nonwoven fabric made of plant fiber as raw material itself is not flame retardant. If you want to endow the spunlace nonwoven fabric with flame retardant properties, you must add additional flame retardants. Currently commonly used fabric flame retardants inc...
