Fastener tape, slide fastener, skin product, and method of forming fastener tape

A slide fastener comprising a fastener tape, wherein the fastener tape comprises two fabric tapes, which extend in a longitudinal direction, and are made by interweaving high-melting warp yarns and weft yarns in longitudinal and transverse directions, wherein a cross-sectional view shows that the fabric tapes each comprise an outer connecting portion and an inner connecting portion, which are arranged left and right in the transverse direction and are connected by the weft yarns;

• the fastener tape further comprises high-melting fastener teeth and sewing thread;
• wherein the fastener teeth are sewn to an outer side of the inner connecting portion through the sewing thread;
• the outer connecting portion is used for connecting a fabric;
• the inner connecting portion comprises a teeth sewing region bound with the sewing thread;
• a low-melting component is provided in at least the teeth sewing region of the inner connecting portion;
• and the low-melting component thermally welds the sewing thread, the warp yarns, and the weft yarns, such that at least the teeth sewing region is formed into a hardened structure;
• and
• the slide fastener further comprises a slider, wherein the slider is bound with the fastener teeth provided on the two fabric tapes of the fastener tape, and the slider is configured to engage or separate two rows of the fastener teeth.

A method of forming a fastener tape comprising:

• forming two fabric tapes, which extend in a longitudinal direction, and are made by interweaving high-melting warp yarns and weft yarns in longitudinal and transverse directions, wherein a cross-sectional view shows that the fabric tapes each comprise an outer connecting portion and an inner connecting portion, which are arranged left and right in the transverse direction and are connected by the weft yarns;
• the method further comprises forming high-melting fastener teeth and sewing thread;
• wherein the fastener teeth are sewn to an outer side of the inner connecting portion through the sewing thread;
• the outer connecting portion is used for connecting a fabric;
• the inner connecting portion comprises a teeth sewing region bound with the sewing thread;
• a low-melting component is provided in at least the teeth sewing region of the inner connecting portion;
• a melting temperature of the low-melting component is lower than a melting temperature of the fastener teeth, the sewing thread, the weft yarns, and the warp yarns;
• after the warp yarns and the weft yarns of the fabric tapes are interwoven and the low-melting component is arranged, the fastener teeth are sewn through the sewing thread;
• heating the inner connecting portion at a heating temperature adapted to the melting temperature of the low-melting component, such that the low-melting component is melted while the high-melting sewing thread, warp yarns, weft yarns, and fastener teeth are not melted;
• and cooling the low-melting component, such that the low-melting component is hardened and thermally welds the surrounding sewing thread, warp yarns, and weft yarns, thereby turning a region where the low-melting component is provided into a hardened structure.
