Abstract

The invention provides a manufacturing method of a low-smoke, low-toxicity and antistatic hook-and-loop fastener. The manufacturing method comprises the following specific steps of: firstly, putting anylon hook-and-loop fastener into a dip dyeing machine for cleaning; dyeing the nylon hook-and-loop fastener; dehydrating the nylon hook-and-loop fastener; respectively dipping a hook surface hook-and-loop fastener and a loop surface hook-and-loop fastener; drying the nylon hook-and-loop fastener; coating the hook-and-loop fastener with an antistatic flame-retardant coating adhesive; drying the nylon hook-and-loop fastener; and finishing the nylon hook-and-loop fastener in a gluing machine by using a hot melt adhesive containing a halogen-free flame retardant. The flame retardant performanceof the hook-and-loop fastener is improved through flame retardant finishing agent dipping, coating by an antistatic flame-retardant coating and finishing by the hot melt adhesive containing the halogen-free flame retardant, the added flame retardant finishing agent, antistatic flame-retardant coating and halogen-free flame retardant are all low-smoke and low-toxicity components, and potential safety hazards during combustion are reduced; and meanwhile, the antistatic flame-retardant coating can reduce static electricity generation, accelerate static electricity dissipation and reduce the electrostatic effect, so that the antistatic flame-retardant coating is suitable for flammable and combustible environments.

Description

technical field [0001] The invention relates to the field of manufacturing methods of hook and loop fasteners, in particular to a manufacturing method of a low-smoke, low-toxicity, antistatic hook and loop fastener. Background technique [0002] Velcro is widely used in various industries due to its convenient operability and strong connection. The existing ordinary nylon hook and loop fasteners, because the daily use environment is mostly a relatively suitable environment, and the requirements for the performance of the hook and loop fasteners are not high, it is enough to realize the basic connection function. However, for some special industry clothing, such as firefighting clothing, its use environment involves extreme environments such as high temperature, flammable and explosive, and higher performance requirements are put forward for the hook and loop fastener. [0003] The existing Velcro generally improves the flame retardant performance of the Velcro by adding fla...
