Description
Technical field
The present invention relates to high-strength fire-retarding elastic fabric and preparation method thereof.
Background technology
For the law enfrocement officials such as army's People's Armed Police's public security afield or when meeting with sudden and violent probably attack, attacking for thermal-flame is faced in meet
Hit；When carrying out tactics technology training, significantly limb action is had, therefore if dress materials lack flexibility or clothes knot
Structure is unfavorable for human body flexible motion, will influence the performance of tactics technology action；In operational training, there is stronger activity intensity,
Human body thermic load rises, it is necessary to which clothes have good gas permeability and penetrability, particularly in the season in hot day or more scorching such as summer
The workplace of heat.
The flame protection prepared by fire resistance fibres such as meta-aramids that the occupational staffs such as steel worker, fire fighter are worn
Clothes, the stretch modulus of its material is big, fiber self-deformation ability is small, and the fire-retardant frock of general structure is also not provided with being beneficial to people
The apparel construction of body motion, therefore limb motion is limited by apparel construction and deformability, the limbs that have impact on labourer are lived
The dynamic free degree, the sense of fatigue so as to have impact on operating efficiency, add labourer；Worker has larger thermic load when working, and needs
Want frock ventilation and perspiration function.
In a word, existing fighting uniform or frock, particularly fire-retardant fighting uniform and fire-retardant work clothes, enough elasticity changes are lacked
Shape ability.And be usually to improve fabric intensity and use closely knit fabric construction, lack larger gap between the yarn in fabric

Overall fire resistance is rung, therefore is not applied.
It is the conventional flame-retardant finishing method of bafta that bafta Proban, which arranges (general Shandong benzene arranges), is to use tetra methylol
The low molecule aqueous solution such as sulfuric acid phosphorus, THPC pads in fabric and controls appropriate active constituent content, allows phosphorus
Based compound is penetrated into the amorphous area and gap of cotton fiber, and controls its water content, then by the quantitative stifling of ammonia, is made
NH3It is crosslinked with the methylol in phosphorus system preshrunk body, forms fire-retardant condensate in fibrous inside, and establish the fire-retardant association of phosphorus nitrogen synergistic
Same effect；The oxidized three valent phosphors made in fiber in fire retardant are changed into pentavalent phosphorus again, make the immobilization of fire retardant in the fibre
Further stabilized.Through as above arranging the bafta of processing, after thermal-flame is run into, phosphorus-containing compound decomposes first
Not volatile phosphoric acid or polyphosphoric acid acid anhydride are produced, dehydration occurs with the hydroxyl of cellulose, carbonizes fiber, so as to reach resistance
Fuel efficiency fruit.Fabrics feel soft, fire resistance after the processing of Proban methods is durable, can bear 50 times (or even 200 times) washing,
And remain to keep good fire resistance and the comfortableness of fabric, be suitable for makeing all kinds of protective garments, bedding, adornment with
And fire-retardant nightwear of children etc., be current durable bafta flame-proof treatment important method.But the disadvantage that general Shandong benzene arranges is
Fabric breaking strength after arrangement declines notable, it will usually reach 20% drop it is strong；Particularly tearing strength has significantly
Reduce.Therefore the application of such fire-retardant process technology is had a strong impact on.
Common polyvinyl and high strength vinylon carry out acetalation processing to the hydroxyl of PVA fibers using formaldehyde and are made, and use first
Aldehyde blocks to the hydroxyl in PVA fibers, considerably reduces the hydroxy radical content in fiber, so as to solve PVA fibers appearance
