[0003] Moreover, the foregoing two pieces of single-sided cloth shall be bonded with glue, and in order to meet basic requirements of the cloth such as repeated cleaning, the glue shall have a strong viscosity. This will cause the glue to become more toxic, and make customers with more sensitive skin prone to allergic problems. In addition, the foregoing glue is a compound, which will lead to environmental pollution if it is improperly discharged to the surrounding environment.
SUMMARY OF THE INVENTION
[0004] The main objective of the present invention is to solve the problem that the double-sided cloth comprising cut-pile fabrics cannot be knitted at one time and needs extra processing.
[0005] The secondary objective of the present invention is to make the double-sided cloth comprising the cut-pile fabrics bond without glue, so as to avoid the harm of glue residues to human health.
[0006] To achieve the foregoing objectives, the present invention provides a method for knitting a double-sided cloth comprising cut-pile fabrics with a circular knitting machine. The double-sided cloth comprising the cut-pile fabrics is composed of a first surface layer and a second surface layer connected with the first surface layer. A plurality of cut-pile fabrics are formed on one side of the second surface layer relative to the first surface layer. The circular knitting machine comprises two correspondingly disposed needle beds. The method includes:
a first surface layer knitting step: operating by one of the needle beds to knit the first surface layer;
a second surface layer knitting step: operating another one of the needle beds to knit a bottom yarn texture and a plurality of loops connected to the bottom yarn texture, and driving a plurality of trimmers disposed on the needle bed which knits the bottom yarn texture and the plurality of loops to cut the plurality of loops to form the plurality of cut-pile fabrics respectively connected to the bottom yarn texture, and constituting of the second surface layer by the plurality of cut-pile fabrics and the bottom yarn texture; and
an interweaving step: operating the two needle beds simultaneously, and connecting the first surface layer with the second surface layer by a plurality of connecting yarns, so as to knit the double-sided cloth comprising the cut-pile fabrics.
[0007] In one embodiment, in the step for knitting the second surface layer knitting, two yarns are fed into one of the needle beds in the knitting process. One of the two yarns is knitted into the bottom yarn texture, and another one of the yarns is connected with the bottom yarn texture and is hooked and hung to form one of the plurality of loops.
[0009] In addition to the foregoing embodiments, the present invention further provides another method for knitting the double-sided cloth comprising the cut-pile fabrics. The method includes:
a second surface layer knitting step: operating one of the needle beds to knit a bottom yarn texture and a plurality of loops connected to the bottom yarn texture, driving a plurality of trimmers disposed on the needle bed which knits the bottom yarn texture and the plurality of loops to cut the plurality of loops to form the plurality of cut-pile fabrics respectively connected to the bottom yarn texture, and constituting of the second surface layer by the plurality of cut-pile fabrics and the bottom yarn texture;
