Problems solved by technology
[0002] With the improvement of people's awareness of protection, especially the needs of individual protection in special industries, there is a large demand for flame-retardant protective functional clothing. The existing flame-retardant yarns used in the production of protective clothing have low strength, itching and burning during use. It is necessary to study and use reasonable fiber combinations with different properties, make full use of the key properties of various fibers, and develop comfortable wearing properties, high strength, flame retardant, carbonized non-melting Drip protective clothing yarn to meet the needs of the production of special flame-retardant protective clothing

Embodiment 1
[0010] Domestic flame-retardant viscose: It is safe and non-toxic, does not produce toxic gas when burned, produces less smoke, has high flame retardancy, and has a long-lasting flame-retardant effect. After carbonization or high temperature of 1100°C, it can maintain its original shape and act as a barrier effect. No melting, no dripping, reducing secondary damage such as burns, and degradable after the end of the service life cycle; bright dyeing, high color fastness.
[0011] The main performance indicators of flame retardant viscose fiber are as follows:
[0012] Fiber linear density 2.2dtex fiber length 51mm Dry breaking strength ≥2.0CN / dtex Limiting Oxygen Index (LOI) ≥35％ Color fastness ≥ grade 4 Alkaline wash resistance ≤2％ Afterburn time ≤2 seconds smoldering time ≤2 seconds smoke density Dm4.0≤5 smoke composition non-toxic molten drip none Safety Ecological Index Class A (OEKO)

Abstract
The invention provides a high-tenacity carbonized flame-retardant yarn and belongs to the technical field of spinning. The high-tenacity carbonized flame-retardant yarn is prepared by the steps of (1)evenly mixing of flame-retardant viscose and aramid 1414; (2) blowing; (3) carding; (4) drawing; (5) roving; (6) spinning; and (7) winding; a flame-retardant viscose fiber, a para-aramid 1414 fiber and a high-strength polyamide filament are blended; producing and processing are carried out according to a blending ratio (in percentage by mass) of 60+ / -3% of flame-retardant viscose, 30+ / -3% of para-aramid 1414 and 10+ / -3% of 30-40D high-strength polyamide filament; and a 14-count yarn is produced by adopting a core-spun yarn production method. A flame-retardant fabric produced by the yarn has good flame-retardant property, is free of melting or dripping in carbonization and has excellent comfort, high dyeing property and high strength.
