Preferably, the low-melting copolyester described in the present disclosure is a copolymer composed of terephthalic acid (PTA), ethylene glycol (EG), and sebacic acid.

In various embodiments of the present disclosure, the low melting point temperature region is formed by embroidering a yarn having a low melting point on a cloth on the high melting point temperature region.

In various embodiments of the present disclosure, the high and low melting temperature regions are formed by knitting or woven yarns having high melting points and low melting points, respectively.

Generally speaking, the present disclosure relates to a method for forming textile items (such as shoulder pads, buttons, pockets, etc.) directly from a thermoplastic fabric in a cost-effective manner.

In order to achieve the above purpose, a polymer fiber or a silk thread (for example, a low melting point copolyester or polyethylene terephthalate fiber) is combined to form a yarn, and the yarn can be embroidered through an advance arrangement. ), Knit (knit) and / or woven (woven) and other methods to make cloth, and then produce the desired thermoplastic cloth, which has high and low melting temperature regions. After exposure to heat, a part of the cloth with a low melting temperature region will melt and eventually harden, while a part of the cloth with a high melting temperature region will remain unmelted and have softness, whereby it can be directly A specific three-dimensional space (3D) type of object is formed on the cloth. In addition, the cloth with the hard and soft regions can be selectively folded into the shape of the desired 3D object.

The monomers of polyethylene terephthalate are terephthalic acid (PTA) and ethylene glycol (EG). During the polymerization, terephthalic acid (PTA) and ethylene glycol (EG) are polymerized to form polyethylene terephthalate. However, if there are aliphatic monomers, in addition to the polyethylene terephthalate segment, it may also form between the aliphatic monomer and terephthalic acid (PTA) or ethylene glycol (EG). Based on the foregoing, the block copolymer forms a modified polyethylene terephthalate, which includes a block structure of a copolymer formed of a polyethylene terephthalate / aliphatic monomer.

The degree of decrease in the melting point of polyethylene terephthalate is inversely proportional to the content of the fatty monomer in the copolymer. In other words, the lower the melting point, the higher the content of the fatty monomer in the copolymer. Preferably, the weight percentage of the fatty group monomer in the copolyester is about 1-20% (wt%).
