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 nontoxic, produces no toxic gas when burning, produces less smoke, has high flame retardancy, and has a lasting flame retardant effect. It can keep its original form after carbonization or at a high temperature of 1,100℃ and play a role in blocking. No melting, no dripping, reducing secondary injuries such as scalding, and being degradable after the end of the service life cycle; Bright dyeing and high color fastness.

[0011] The main performance indexes of flame retardant viscose fiber are as follows:

[0012] Fiber linear density 2.2dtex fibre length 51mm Dry breaking strength ≥2.0CN / dtex Limiting oxygen index (LOI) ≥35％ colour fastness ≥4 grade Alkali washing resistance ≤2％ after flame time ≤2 seconds Smoldering time ≤2 seconds Smoke density Dm4.0≤5 Flue gas composition non-poisonous Melting dripping without Ecological index Class a (OEKO)

Abstract

A high-strength carbonized flame-retardant yarn belongs to the technical field of spinning. Flame-retardant viscose and aramid 1414 are evenly mixed; (2) Blowing; (3) Carding; (4) Drawing; (5) Roving; (6) Spun yarn; (7) Winding; Flame-retardant viscose , para-aramid 1414, and high-strength nylon filament are blended according to the blending ratio of flame-retardant viscose 60±3%, 1414 para-aramid 30±3%, and high-strength nylon 30‑40D filament 10±3% (mass percentage) carries out production processing, adopts core-spun yarn production mode to produce 14 yarns. The flame retardant fabric produced by this yarn has good flame retardancy, carbonization without molten drops, excellent comfort, high dyeing performance and high strength.

Description

Technical field [0001] The invention relates to the technical field of spinning, in particular to a high-strength carbonized flame-retardant yarn. technical background [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 clothing. The existing flame-retardant yarn for protective clothing production has some problems in use, such as low strength, prickling, melting and dripping after burning, single dyeing, etc. It is necessary to study and apply reasonable fiber collocation with different properties, and make full use of the key properties of various fibers, so as to develop protective clothing yarn with comfortable wearability, high strength, flame retardancy, carbonization and no melting drops. Inventive content [0003] The purpose of the present invention is to overcome the fact that the current yarn used for the production of flame-retard...
