## Abstract

A care label consists of a strip-shaped fabric band into which an antenna structure is sewn during the production of the fabric band. A small detection plate is fixed to the fabric band next to the fold line in the region of the antenna structure. To form the care label, the fabric band is folded along the fold line such that the antenna structures of the folded sections are superimposed after the folding process. The small detection plate comprises a chip with a coupling loop and together with the antenna structure forms a textile transponder.

## Claims

### Claim 1

A folded and printed care label for textiles, comprising:
an antenna structure woven into a section of a fabric band that forms a care label;
a detector plate attached to the fabric band next to a centrally disposed fold line close to the antenna structure; and
the fabric band being folded along the fold line to create two folded sections that each contain a portion of the antenna structure, said fabric band being folded in such manner that the portions of the antenna structure contained in the folded sections are superposed on one another after the fold is made;
wherein the detector plate is sewn onto the care label.

### Claim 2 (depends on 1)

The care label as recited in claim 1, wherein the antenna structure is arranged to minor symmetrically about the fold line.

### Claim 3 (depends on 1)

The care label as recited in claim 1, wherein the portions of the antenna structure contained in the folded sections lie congruently with one another after folding.

### Claim 4 (depends on 1)

The care label as recited in claim 1, produced by the following process:
a) while an endless, strip-shaped fabric band is being produced as the basic material for the care label, an endless antenna structure made from electrically conductive material is simultaneously woven into the fabric band,
b) the antenna structure is introduced as a warp or weft thread by means of a thread having a conductive element,
c) the antenna structure has a periodically repeating design,
d) the fabric band is furnished with periodically repeating reference marks that define cutting lines,
e) a cut off portion between two adjacent reference marks forms the basis for a single care label,
f) a detector plate comprising a chip and a coupling loop is located close to the antenna structure on the care label for coupling with the antenna structure, and
g) the cut off portion of the fabric band is folded along a central fold line.

### Claim 5 (depends on 1)

The care label as recited in claim 1, wherein the antenna structure is formed by an electrical field transmitter.

### Claim 6 (depends on 1)

The care label as recited in claim 1, wherein a new antenna structure is formed by the folding operation, which new antenna structure enlarges the bandwidth of the transponder.

### Claim 7 (depends on 1)

The care label as recited in claim 1, wherein the detector plate is coupled without contact into the woven and folded antenna structure.

### Claim 8 (depends on 1)

The care label as recited in claim 1, wherein the antenna structure is formed by a conductive dye printed onto the fabric band that has been coated with plastic.

### Claim 9 (depends on 1)

The care label as recited in claim 1, wherein the fabric band is coated with plastic, and the antenna structure in the fabric band is formed by an additional conductive coating.

### Claim 10 (depends on 1)

The care label as recited in claim 1, wherein antenna threads are woven into the fabric band to form the antenna structure, said antenna threads comprising insulated wires.
