The safety requirements for toys filled with foam particles, in addition to meeting the requirements of sanitation and environmental protection, more importantly, cannot be eaten into the mouth by children under three years old, which is what the toy industry commonly calls "dangerous small parts." -This requires that the seam pulling force of any part of the toy must reach 70 Newtons, to ensure that the plastic particles will not fall out during the normal use and reasonable abuse of the toy by children.
In the production process of toys, the following measures should be taken to ensure that the pull tension of the toys meets the requirements and ensure the safety of the foam particles flowing in the toys. -The following is a brief description of the production process control measures for the particle toy seam tension to meet the requirements of toy standards:
(1) Add reinforcement belt (commonly known as cotton rope) at the sewing position, single-thread sewing, or even double-thread sewing to increase the tensile strength of the product and prevent particle leakage.
(2) According to the characteristics of whether different fabrics are easy to be stacked and easy to slide, the stop of the sewing process is appropriately increased. (Not less than 1 minute and a half or so)
(3) Consider the actual elasticity of the fabric density and the size of the foam particles, and stipulate a suitable needle pitch of the sewing machine.
(4) Select a sewing thread with the same intensity and greater strength as the fabric color.
(5) When sewing the toy pieces, the stitches of the pieces must be turned back and forth to prevent the sewing thread from breaking or loosening.
(6) Strengthen the inspection of semi-finished products, including the inspection of the stop, whether the needle is down, whether the suede has holes or cracks, etc.
After taking the above measures, if the sample inspection is carried out according to the corresponding requirements of GB2828-87, the joint pulling force of the finished particle toy products will meet the requirements of the toy safety standards. -In this way, it is ensured that the filled foam particles in the toy will not fall out during the normal use of children and a reasonable and predictable abuse test, that is, the safety of the filled foam particles is guaranteed.
