Discussion on some problems of flame retardant fabrics and flame retardant fabrics (1)

1. Product production The main misunderstandings in product production are: focus on protection requirements and ignore general requirements; focus on internal quality and ignore appearance.

Many manufacturers often ignore general requirements when producing protective equipment. For example, the smoldering time, afterburning time,

The flame retardant properties such as damage length are very good, but the strength is seriously decreased, the hand feel is hard, and the color fastness is poor; the produced insulating shoes have withstand voltage,

The insulation properties such as leakage current are all qualified, but the sole is not wear-resistant, easy to break, the leather of the shoe is thin or aging, etc., the contradiction to the general requirements is covered up by the protective performance.


At present, the biggest opinion of employees about the anti-static cloth for protective equipment is not the poor protective performance, but the poor wear resistance caused by the general performance, which is not suitable for use.

The user unit formulates the use cycle of protective equipment according to the wearing time of general clothing and civilian products, but they cannot operate normally due to the long cycle.

The reason is that the general performance quality of protective equipment is far lower than that of similar civilian products. In order to ensure the safety of employees, it can only run ahead of the cycle,

If it is broken, it will be replaced. Some employees have used the same amount of protective equipment after two years.


According to actual statistics, about 70-80% of footwear protective equipment can not be worn for the period, and 50% can only be worn for half of the period.

Protective equipment such as clothing can only be worn to 80% of the cycle. The fundamental reason why protective equipment is not as durable as similar clothing is that only in the production process of protective equipment

It pays attention to the protective performance, but ignores the general requirements, and even shoddy and cut corners on the raw materials that do not affect the protective performance.

For example, if the soles of rubber soles are considered protective equipment, more reclaimed rubber is used and natural rubber is reduced; the fabrics of work clothes are woven with inferior yarns.


A factory specially took out the proud work clothes produced by its own factory when it received the leaders who inspected labor safety work by the central government and let the leaders wear them to the scene.

When I came back from the scene, I found that there were only two buttons left on my shirt, which made the reception staff very embarrassed. In many labor sites, rubber soles and leaky toes can be seen everywhere.

Clothes, buttons, sleeves, pants open, etc. The appearance quality of protective equipment is generally regarded by people. It is believed that only one protective equipment is required, and the appearance should not be required.

This is not only a prejudice against protective equipment, but also a prejudice against labor and workers, believing that labor can only be condensed and careless.

On the premise of ensuring protective performance and use performance, we should strive to be beautiful, generous, and fit; in order to improve workers' desire to use and pride in their work.


2. Flame retardant fabrics The misunderstanding of the quality inspection of protective equipment in the inspection of anti-static fabric products is: the inspection of flame retardant grades and the inspection of protective performance indicators,

Light inspection of general indicators; put more emphasis on ex-factory inspection and light in-service inspection; pay more attention to national and provincial inspections, and light up inspections by user units.

Most of the inspection stations pay more attention to the protection performance inspection of protective equipment, but despise the general performance inspection, and some departments do not carry out the general performance inspection at all.

There are also some quality inspection departments that do not have the conditions for general performance inspection.

It also does not carry out the inspection of shoe leather; chemical fiber products and plastic products are not subject to aging and physical allergies to the human body, etc.

This phenomenon also contributes to the disadvantage that manufacturers do not pay attention to the general performance quality. Inspection work should include those that really affect worker safety and

Inspection during healthy use, that is, in-service inspection, because after the protective equipment is distributed to workers,


During the whole use cycle, its protective performance varies greatly due to various factors, including the reasons of the protective equipment itself and the external reasons of the environment and users.

For example, when investigating 563 seat belts used by a structural installation team, it was found that 65% of the seat belts were burnt to varying degrees.

As high as 84.2%, the safety ropes of some seat belts broke when two people pulled them. 60%~84% of users figured out that it is easy to remove the locking ring of the hook.

Some users of the anti-ultraviolet fabric do not know the function of the various parts of the seat belt, so they can modify it at will, some remove the locking ring, some remove the harness,


Some cancel the rope cover, etc. There are 63 seat belts used in one unit, and only four are really complete. Overdue service is common, generally as high as 65.5%.

An inspection of a two fall fatality accident revealed that the deceased was wearing a two-year overdue seat belt and a safety rope that was scorched by steam welding.

The flame-retardant multi-functional composite cloth inspected the insulating shoes used on site, and found that 65% of the insulating shoes that had been used for more than half a year did not meet the standard requirements.

Some shoes break down when they are electrified, among them, the soles are not resistant to wear, thin, leak, or break, and the number is 8. %. The 532 pieces of safety nets inspected have "% can not be hung correctly, almost

100% cannot be stored according to the standard requirements after use, and the sampling inspection during use has not been done.


The continued application of these lost and degraded protective equipment greatly promotes the user's fluke and dependence, and increases the insecurity factor.


It is unrealistic to rely on national, provincial and municipal inspection stations for these in-service inspections. Only by fully mobilizing the inspection force of enterprises (users) and implementing national,

The three-level inspection of several provinces (cities) and enterprises fully covers the quality supervision and inspection of protective equipment. The tasks of inspection stations within the enterprise are:

Conduct in-service sampling inspections of protective equipment in use; supervise enterprise supply departments to organize supply according to quality standards;

The general protective equipment not inspected by the provincial (city) inspection station shall be inspected according to the standards for flame-retardant fabrics at all levels; the correct use of protective equipment shall be supervised according to the standard requirements.
