Abstract

A method for manufacturing a fastener stringer according to the present invention, include a dyeing step for dyeing a fastener stringer including an element row fixed to a side edge portion of a tape made of fiber, a dye cleaning step for removing excess dye from the fastener stringer, a water repellent treatment step for adhering a non-fluorine-based water repellent agent to the fastener stringer, and a pre-dyeing degreasing step for degreasing oil and fat adhered to the fastener stringer by a wet process.

First claim

What is claimed is:

1. A method for manufacturing a fastener stringer, the method comprising:
a dyeing step for dyeing a fastener stringer including an element row fixed to a side edge portion of a tape made of fiber;
a dye cleaning step for removing excess dye from the fastener stringer;
a water repellent treatment step for adhering a non-fluorine-based water repellent agent to the fastener stringer; and
a pre-dyeing degreasing step for degreasing oil and fat adhered to the fastener stringer by a wet process.

2. The method for manufacturing a fastener stringer according to claim 1 , wherein
in the dye cleaning step, an excess dyeing assistant is removed from the fastener stringer in addition to the excess dye.

3. The method for manufacturing a fastener stringer according to claim 1 , wherein
in the pre-dyeing degreasing step, a degreasing scouring step for removing the oil and fat adhered to the fastener stringer by using a scouring agent is performed, and a scouring agent cleaning step for cleaning the fastener stringer to remove the scouring agent is performed after the degreasing scouring step.

4. The method for manufacturing a fastener stringer according to claim 3 , wherein
the scouring agent includes a surfactant and an alkaline agent.

5. The method for manufacturing a fastener stringer according to claim 3 , wherein
in the scouring agent cleaning step, hot water is used to remove the scouring agent and the oil and fat.

6. The method for manufacturing a fastener stringer according to claim 1 , wherein
the dye cleaning step includes a post-dyeing degreasing-and-cleaning step for degreasing the oil and fat adhered to the fastener stringer and cleaning the excess dye and dyeing assistant by using a soaping agent.

7. The method for manufacturing a fastener stringer according to claim 6 , wherein
the soaping agent includes a surfactant and an alkaline agent.

8. The method for manufacturing a fastener stringer according to claim 1 , further comprising:
a heat setting step for heating the fastener stringer before the pre-dyeing degreasing step.
