Description

The preparation method of arc lace shoulder belt

Technical field

The present invention relates to a kind of preparation method of shoulder straps of bra for ladies, especially a kind of preparation method of arc lace shoulder belt.

Background technology

At present, along with people pursue and are on the increase the individual character on clothes, also more and more higher to the requirement of the moulding of brassiere, outward appearance.Present commercially available many brassieres, not only on cup surface or edge with trimming cloth, and on shoulder belt also with lace.Refer to Fig. 1, it illustrates a kind of brassiere with arc lace shoulder belt, comprise brassiere body 1 and arc lace shoulder belt 2, the edge sewing of the cup 11 on brassiere body 1 has matting 12, on arc lace shoulder belt 2, near the part that connects cup 11 one end, decorates and has arc lace 21.Refer to Fig. 1, this kind of arc lace shoulder belt 2 comprises that two ends are with the degree of tightness shoulder belt body 20 of hasp, be fixedly connected on the arc lace 21 on degree of tightness shoulder belt body 20 along its length, and one end of the end of this arc lace 21 and degree of tightness shoulder belt body 20 is fixed together.

In the prior art, the preparation method of this kind of arc lace shoulder belt comprises the following steps:

Prepare degree of tightness shoulder belt body step;

Prepare arc lace step: lace cloth is cut and obtains arc lace 21 according to sanction plate, refer to Fig. 2, the both sides of this arc lace 21 have respectively straight line 211 and arc-shaped side 212, and it is wide that the shape of this arc lace 1 is narrow centre, two in the longitudinal direction;

Make integrating step: alignd with one end of described arc lace 21 in the one end after described degree of tightness shoulder belt body 20 tensions, then described degree of tightness shoulder belt body 20 is made along its length on the straight line of described arc lace 21, the end infolding certain length then described arc lace 21 and described degree of tightness shoulder belt body 20 being fixed is sewn into seam portion 213.

Refer to Fig. 3, because a pair of arc lace shoulder belt on same brassiere is when making, not of uniform size the causing of pulling force when degree of tightness shoulder belt body 20 is tightened up, cause arc lace 21 different in size show and end width that arc lace 21 is made after seam portion 213 from the end infolding of degree of tightness shoulder belt body 20 different, as shown in Figure 3, in this pair of arc lace shoulder belt, the width K of the shoulder belt seam portion in left side is greater than the width k of the seam portion on right side, when being configured in the both sides of same brassiere, will cause this pair of arc lace shoulder belt the asymmetric defect of arc lace outward appearance of shoulder belt.

Summary of the invention

In order to overcome the defect of above-mentioned prior art, the preparation method that the object of this invention is to provide arc lace shoulder belt, the arc lace shoulder belt outward appearance of this kind of preparation method making is consistent, avoided, because the length of the degree of tightness shoulder belt body arc lace that tightening force difference causes when making after making is different and the different defect of seam portion width, having improved production efficiency and the production yield of arc lace shoulder belt.

For achieving the above object, the present invention by the following technical solutions:

A preparation method for arc lace shoulder belt, comprises the following steps: prepare degree of tightness shoulder belt body step, prepare arc lace step and make integrating step, it is characterized in that:

The detailed process of described preparation arc lace step is: lace cloth is cut and obtains arc lace according to sanction plate, described arc lace comprises curved portions and is positioned at the wide connecting portion of curved portions front end, the both sides of described curved portions have respectively straight line and arc-shaped side, the front end of described connecting portion along the length direction of described straight line from described curved portions extend forward and the width on its bearing of trend identical;

The described detailed process of making integrating step is: by the end part aligning of the connecting portion of the one end after described degree of tightness shoulder belt body tension and described arc lace, then described degree of tightness shoulder belt body is made along its length on the straight line and described connecting portion of described arc lace, then the end while infolding certain length of the connecting portion of described arc lace and described degree of tightness shoulder belt body is sewn into seam portion.

Compared to prior art, the preparation method of arc lace shoulder belt provided by the invention, have the following advantages: because arc lace has after cutting for generation of the curved portions of lace effect and makes the connecting portion of seam portion for infolding, when degree of tightness shoulder belt body is made along its length on the straight line of arc lace, even if the tightening force of degree of tightness shoulder belt body is different, unclamp after degree of tightness shoulder belt body, on arc lace wide connecting portion after shrinking again the width of infolding also can be consistent, guaranteed like this uniformity of seam portion width when each arc lace shoulder belt is made, the outward appearance of a pair of arc lace shoulder belt that guarantees each brassiere is symmetrical, improve production efficiency and produced yield.
