Embodiment Construction

[0015] The technical solution of the present invention will be described in detail below.

[0016] The invention discloses an aramid fire-proof and flame-retardant yarn. The aramid fire-proof and flame-retardant yarn is composed of polyisophthalamide m-phenylene diamide fiber with a mass ratio of 93%, and polyterephthalamide fiber with a mass ratio of 5%. P-phenylenediamine, 2% carbon guide fiber composition.

[0017] The preparation method of the aramid fireproof flame retardant yarn of the present invention comprises the following steps:

[0018] a Raw material preparation: uniformly mix 93% poly-m-phenylene isophthalamide fiber, 5% poly-p-phenylene terephthalamide, and 2% carbon fiber in proportion. The method of uniform mixing is to spread antistatic oil and water to cover the plastic cloth, and let the oil and water suffocate for 24-28 hours.

[0019] b Cleaning process: Load the raw materials into the mixing opener, card opener, cotton feeder, vibrating cotton feeder, ...

Abstract

The invention provides a fire-prevention and flame-retardant armid fiber yarn. The armid fiber yarn comprises the following components by weight ratio: 93% of polyisophthaloyl metaphenylene diamine fiber, 5% of poly-p-phenylene terephthamide and 2% of carbon-guiding fiber. The invention also provides a preparation method of the fire-prevention and flame-retardant fiber yarn. The preparation method comprises the steps of a. raw material preparation, b. blowing process, c. cotton carding process, d. drawing and doubling process, e. spinning process and f. post processing process. The fire-prevention and flame-retardant aramid fiber yarn has the beneficial effects that the yarn levelness is uniform, the strength is strong, the yarn hairness and the yarn fault are few, the flame retardant property is good, the aramid fiber yarn has good radiation resisting property, acid resisting property, alkali resisting property and other various chemical properties, cannot be softened and melted under high temperature due to high temperature resistance, and is stable in prolongation due to good mechanical property so as to be completely suitable for fire-prevention and flame-retardant requirements of spaceflight, military use and civil use.

Description

technical field [0001] The invention relates to a yarn, in particular to an aramid fire-proof and flame-retardant yarn and a manufacturing method thereof. technical background [0002] The society is developing and progressing, science and technology are constantly changing with each passing day, and various fields are constantly proposing the need for different types of fire-resistant and flame-retardant fabrics. [0003] At present, general flame-retardant chemical fibers, such as polyester, viscose, acrylic, etc., can only be used in decoration products in some public places such as hotels and automobiles due to factors such as strength and flame-retardant properties. It cannot be used in aviation, aerospace, fire-fighting clothing, flame-resistant gloves, boiler flue gas filter materials, military industry requirements, etc. where the temperature is relatively high, and these fields have certain specific requirements for high-performance fire-resistant and flame-resistan...
