Embodiment 1

[0032] Put the perlite ore in a muffle furnace, roast at a high temperature of 950°C for 20 minutes, and cool down to room temperature to obtain expanded perlite. Mix basalt rock powder and expanded perlite at a mass ratio of 1:3 and place them in a planetary ball mill , ball milled for 20 minutes at a rotational speed of 400r / min to obtain the mixed material; in parts by weight, weigh 20 parts of toluene diisocyanate, 30 parts of polyester diol, 30 parts of viscose collagen solution, and 1 part of mixed material , 1 part of nickel sulfide, 1 part of ethylenediamine, and vacuum degassing polyester diol at a temperature of 100 ° C and a pressure of 45 Pa for 1 h to obtain a reactant. ℃, the stirring speed is 100r / min, stirring and reacting for 1h, and the pressure is 45Pa to vacuumize and debubble for 30min to obtain the prepolymer. Add viscose glue, mixed materials and nickel sulfide to the prepolymer. Stir at 300r / min for 20min to obtain a mixed prepolymer, add ethylenediamin...

Embodiment 2

[0034] Put the perlite ore in a muffle furnace, roast at a high temperature of 975°C for 25 minutes, and cool to room temperature to obtain expanded perlite. Mix basalt rock powder and expanded perlite at a mass ratio of 1:3 and place them in a planetary ball mill , ball milling at a speed of 450r / min for 25min to obtain the mixed material; in parts by weight, weigh 25 parts of toluene diisocyanate, 35 parts of polyester diol, 35 parts of viscose collagen solution, and 5 parts of mixed material , 5 parts of nickel sulfide, 1 part of ethylenediamine, and the polyester diol is degassed in vacuum at a temperature of 105 °C and a pressure of 50 Pa for 1 hour to obtain the reactant. Toluene diisocyanate is added to the reactant, and the temperature is 85 ℃, the stirring speed is 150r / min, after stirring and reacting for 1h, vacuumize and debubble under the pressure of 50Pa for 35min to obtain the prepolymer. Stir at 350r / min for 25min to obtain a mixed prepolymer, add ethylenediami...

Embodiment 3

[0036] Put the perlite ore in a muffle furnace, roast at a high temperature of 1000°C for 30 minutes, and cool to room temperature to obtain expanded perlite. Mix basalt rock powder and expanded perlite at a mass ratio of 1:3 and place them in a planetary ball mill , ball milling for 30 minutes at a rotating speed of 500r / min to obtain the mixed material; in parts by weight, weigh 30 parts of toluene diisocyanate, 40 parts of polyester diol, 40 parts of viscose collagen solution, and 10 parts of mixed material , 10 parts of nickel sulfide, 2 parts of ethylenediamine, and the polyester diol is degassed in vacuum at a temperature of 110 °C and a pressure of 55 Pa for 2 hours to obtain the reactant. ℃, the stirring speed is 200r / min, after stirring and reacting for 2h, vacuumize and debubble for 40min under the pressure of 55Pa to obtain the prepolymer. Stir at 400r / min for 30min to obtain a mixed prepolymer, add ethylenediamine to the mixed prepolymer, and stir rapidly at a temp...

Abstract

The invention relates to a production method of a flame-retardant knitted mattress cloth and belongs to the technical field of home textile materials. The production method has the advantages that polyurethane and viscose are blended and the surface of fibers is coated with polylactic acid to allow hairness unevenly arranged on the yarn to fit the yarn, yarn rigidity is lowered, yarn softness is increased, friction coefficient is reduced, and the knitting of the knitted mattress cloth is benefited; the polyurethane is high in mechanical strength and oxidation stability, high in flexibility andresilience and excellent in oil resistance, solvent resistance, water resistance and fire resistance; the moisture absorption of the viscose can meet the physiological requirements of human skin, andthe viscose is smooth, cool, breathable, anti-static, anti-ultraviolet, bright in color, good in color fastness and the like; the polylactic acid is good in heat stability, good in solvent resistance, biodegradable and good in biocompatibility, glossiness, transparency, touch and heat resistance, and the produced flame-retardant knitted mattress cloth is good in mechanical performance and flame retardance.

Description

technical field [0001] The invention relates to a preparation method of flame-retardant knitted mattress cloth, which belongs to the technical field of household textile materials. Background technique [0002] From the perspective of development trend, home textiles have become an overall consumption category, and mattress fabrics occupy an important position in this category. The mattress cloth is wrapped on the outer layer of the mattress and fixed by pins, and its various performances directly affect the quality and grade of the mattress. The mattress cloth covers the upper layer of the mattress, so the bed fabric is quite special. In addition to the beautiful and generous pattern, its requirements are: first, it has good shape retention and covering properties, and has a strong sense of concave and convex; second, it is stronger. Large, can withstand a certain pulling force, and has the ability to resist bursting and tearing; third, it has good moisture absorption and ...
