US 2018/0127901 A1 · METHOD FOR MANUFACTURING HEATING SHEET AND APPARATUS FOR MANUFACTURING SAME

Abstract

The present invention relates to a method for manufacturing a heating sheet, the method comprising the steps of: a) weaving a weft including a carbon-coated weft W1 and a normal weft W2 and a warp including a metal wire into a fabric; b) cutting the woven fabric and connecting a power supply line to an electrode lead part by using, as the electrode lead part, a portion where the metal wire is located at the end of the cut fabric; and c) shielding the entire sheet-type fabric including the fabric and the power supply line by coating the same with an outer sheath, wherein, in step a), the carbon-coated weft W1 and the normal weft W2 satisfy formula 1 below: 0.2≤d1/d2≤0.8 [Formula 1] [In formula 1, d1 is the denier of the carbon-coated weft W1 and d2 is the denier of the normal weft W2.]

A method for manufacturing a heating sheet, comprising:

a) weaving a weft including a carbon-coated weft W1 and a normal weft W2 and a warp including a metal wire into a fabric;
b) cutting the woven fabric and connecting a power supply line to an electrode lead part, wherein a portion of an end of the cut fabric in which a metal wire is located is used as the electrode lead part;
and
c) coating the entire sheet-type fabric, which includes the fabric and the power supply line, with an outer sheath to shield the entire sheet-type fabric from the outside,
wherein, in step a), the carbon-coated weft W1 and the normal weft W2 satisfy the following Equation 1:
0.2≤d1/d2≤0.8 [Equation 1]
wherein d1 represents a denier of the carbon-coated weft W1, and d2 represents a denier of the normal weft W2.
