Abstract

The invention provides a preparation method of flame-retardant cool cellulose fibers for summer curtains. The preparation method comprise the following steps of preparing a composite flame retardant slurry, preparing an ice-cooling agent slurry, preparing a blended spinning solution, and performing spinning. The flame retardant contains magnesium hydroxide microcapsules, and rare earth lanthanum chloride microcapsules are added into the composite flame retardant, so that the flame retardant effect of the flame retardant can be enhanced, lanthanum chloride has a relatively good antibacterial effect, and therefore a curtain prepared from the fiber has a relatively good antibacterial effect. The dry breaking strength of the prepared fiber is 1.86-2.13 cN/dtex, the wet breaking strength is 0.95-1.16 cN/dtex, the limit oxygen index is 28.3-30.6%, the staphylococcus aureus inhibition rate is 99.2-99.9%, the escherichia coli inhibition rate is 98.6-99.9%, the UPF value is 42-44, and the UVA value is 3.92-4.65%.

Description

technical field [0001] The present invention relates to a flame retardant cool cellulose fiber and a preparation method thereof, in particular to a composite cellulose fiber with cellulose fiber as a matrix, which has the functions of flame retardant, cool, and UV protection, and is especially suitable for use in summer A curtain belongs to the technical field of textiles. Background technique [0002] In the hot summer, the sun is dazzling, and the curtains are drawn, which not only blocks the strong light, but also isolates part of the heat. If the curtains are thinner, the effect of blocking light is poor, and it will dazzle the eyes through the curtains. Strong light shines through the curtains, and people in the room can clearly feel the temperature rise. If the curtains are thicker, although the effect of blocking light is good, but more materials are used, the weight of the curtains is heavier, and the disassembly and cleaning are not as convenient as thin materials...
