Embodiment 1

[0027] Flame-retardant viscose fiber and cotton fiber were respectively carded into slivers, and the slivers were blended according to the blending ratio of 20:80. After spinning, yarns with a yarn count of 15 tex and a twist of 700 twists / m were produced. Utilize the air-jet loom to weave the yarn to make a grammage of 150g / m 2 Plain weave. Prepare a dye bath in which the reactive dye concentration is 1% (o.w.f), the sodium sulfate concentration is 10g / L, and the sodium carbonate concentration is 5g / L, and the bath ratio is 1:10. Dyeing was carried out at 50°C, and the dyeing time was 40min. According to the GB 5454-198 test standard, the limiting oxygen index of the dyed fabric is 28%.

Embodiment 2

[0029] Flame-retardant viscose fiber and cotton fiber were respectively carded into slivers, and the slivers were blended according to the blending ratio of 30:70. After spinning, yarns with a yarn count of 20 tex and a twist of 800 twists / m were produced. Utilize the air-jet loom to weave the yarn, and the grammage is 180g / m 2 Twill fabric. Prepare reactive dye concentration as 2% (o.w.f), sodium sulfate concentration as 15g / L, sodium carbonate concentration as the dye bath of 10g / L, bath ratio is 1:20. Dyeing was carried out at 50°C, and the dyeing time was 50 minutes. According to the GB 5454-198 test standard, the limiting oxygen index of the dyed fabric is 29%.

Embodiment 3

[0031] Flame-retardant viscose fiber and cotton fiber were carded into slivers respectively, and the slivers were blended according to the blending ratio of 40:60. After spinning, yarns with a yarn count of 20 tex and a twist of 800 twists / m were produced. Utilize the air-jet loom to weave the yarn, and the grammage is 180g / m 2 Plain weave. Prepare a dye bath in which the direct dye concentration is 2% (o.w.f), the sodium sulfate concentration is 15g / L, and the sodium carbonate concentration is 10g / L, and the bath ratio is 1:20. Dyeing was carried out at 50°C, and the dyeing time was 50 minutes. According to the GB 5454-198 test standard, the limiting oxygen index of the dyed fabric is 29%.

Abstract

The invention relates to a novel flame retardant fabric, a preparation method and an application thereof, particular to a blended yarn weaved fabric based on novel flame retardant viscose, a preparation method and an application thereof. The flame retardant viscose is prepared by blended spinning with nanometer SiO2 and cellulose solution; wherein the blended ratio of the flame retardant viscose and natural fiber is 20:80 to 80:20. The invention also provides the preparation method of the flame retardant blended yarn weaved fabric. As the nanometer SiO2 particles are adopted as inorganic flame retardant, the novel flame retardant blended yarn weaved fabric is good in fire resistance; limited oxygen index is more than 28%, meltdown or dripping can not appear when combusting, only a small quantity of flue gas which is safe and innoxious is produced, and the fabric is washing resistant and chemical treatment resistant. The invention has air and moisture permeability and soft feel. The blended yarn weaved fabric is mainly composed of the flame retardant viscose and cotton fiber, and can be applied to preparation of bedding such as bed sheet, quilt cover, pajamas, etc.

Description

technical field [0001] The invention relates to a novel flame-retardant fabric, a preparation method and an application. In particular, it refers to a blended fabric based on a novel flame-retardant viscose fiber, a preparation method and an application thereof. Background technique [0002] The fire caused by the burning of fiber products has become one of the major disasters in modern society. The results of the investigation of the fatal accidents caused by fire show that the fire caused by interior decorations and textiles occupies the first place. The harmful gas released at the time is much more harmful to the human body than flame-retardant textiles. Therefore, in order to prevent fires, the production of flame-retardant fibers has received more and more attention. [0003] At present, the use of flame-retardant fibers and their products has been required in the form of laws and mandatory regulations at home and abroad. For example, the recently passed "Fire Law" c...
