Flame retardant protective equipment

Flame-retardant protective products include flame-retardant protective
clothing, covering fabrics in flammable environments, etc. Flame-retardant
protective clothing refers to protective clothing that after contact with flames
and hot objects within a certain time can prevent them from igniting, catching
fire and smoldering. It is suitable for the wearer to wear protective clothing
in places with open flames, sparks, operations near molten metal, and places
with flammable substances and fire hazards. Not suitable for flame retardant
protective clothing worn for firefighting.

Experiments show that three kinds of flame-retardant finishing fabrics of
cotton fabrics and four kinds of flame-retardant finishing fabrics of polyester
fabrics meet the requirements of flame-retardant protection Meet the
requirements for afterflame time, smoldering time and scduration. However, since
protective clothing should not have melting and dripping phenomena, and although
the melting and dripping phenomena of the four flame retardant finishing fabrics
of polyester fabrics have been alleviated, they still exist, so the four kinds
of flame retardant finishing fabrics of lacquer fabrics can not meet the
requirements of flame retardant protective clothing. The performance of various
flame retardant finishing fabrics used in protective clothing was evaluated
using the Borda number method. The main evaluation indicators of flame retardant
protective clothing are: limiting oxygen index, heat release rate, specific
extinction area, breaking strength, abrasion resistance index, air permeability,
moisture recovery, moisture permeability, folding recovery angle and Cro value.
, Flame retardant protective clothing has relatively high requirements for flame
retardant performance, and also has certain requirements for breaking strength
and moisture permeabilityness. Therefore, the weight distribution of the five
properties of oxygen index, heat release rate, specific extinction area,
breaking strength and moisture permeability is relatively large.

People usually do not have high requirements for flame retardant fabrics in
their everyday clothing, but in the event of a fire, the clothing has a certain
degree of fire resistance Flammability is of great importance for personal
safety. Children and the elderly in particular find it difficult to move in the
event of a fire, which makes flame-retardant clothing all the more important.
The main rating indicators of clothing are: limiting oxygen index, breaking
strength, abrasion resistance index, drape coefficient, air permeability,
moisture recovery, moisture permeability, fold recovery angle and Cro value.

For clothing, summer clothing and winter clothing focus on different designs,
and the requirements for particular designsgenes are also different, so the
weight distribution of each performance and certain of these properties is also
different. People\'s requirements for summer clothes are mainly strong, good wear
resistance, soft fabric, good air permeability, good moisture absorption and
vapor permeability, and good heat dissipation. Therefore, the weight
distribution of breaking strength, wear resistance index, drape coefficient, air
permeability and moisture permeability is relatively large. Winter clothing has
higher requirements for breaking strength, wear resistance and heat
preservation. The weight distribution of individual performance is relatively
large.
