3 reasons for you to understand the difference between exteriorly bonded sewing threads and locally bonded sewing threads

First, the difference of production process:

1.exteriorly bonded sewing threads, in accordance with the type and color of the customer's needs, first do a dyeing and finishing process, using a single-line drafting of the plastic processing method, wrapped in a thin layer of transparent glue on the outside of the strand to facilitate the strands Bonding to achieve a bonded effect.

2.internally bonded sewing threads, in the process of twisting, adding a low-melting-point thermal fuse in the middle of the strands, and the thermal fuses wrapped in the middle of the strands are melted after being set by heating to bind the strands together, thereby To achieve the effect of bonded, and finally according to the needs of the customer model, color dyeing and finishing.

Second, the difference between the bonded effect:

Externally bonded plastic threads Because the bonded glue is wrapped on the outside of the wire, the color of the glue is often changed so as to produce color difference. After many times of friction or friction in the sewing process by needles and other external forces, loose strands are likely to appear.

Since the internally bonded sewing threads are internally bonded and then dyed after being bonded, these defects are well prevented.

Third, the difference between sewing sewing effect:

The externally bonded sewing threads are hard and the externally bonded adhesive is also liable to generate dust contamination in the needle car, and the internally bonded sewing threads are soft and smooth, thereby greatly improving the sewing performance of the Bondi cable.

Summary: internally bonded sewing threads greatly advance the production of exteriorly bonded sewing threads in terms of production principle, sewing performance, and production efficiency.
