Abstract
The utility model belongs to the technical field of the sewing thread, especially, relate to a sewing thread. It has solved the high technical problem of prior art cost. A sewing thread comprises a main thread and a plurality of auxiliary threads twisted on the main thread, wherein a first flame-retardant layer is arranged in the circumferential direction of the main thread, two adjacent auxiliary threads are mutually leaned together, a second flame-retardant layer is arranged on an arc convex surface of the outer side of each auxiliary thread, which is radially far away from the main thread, and the second flame-retardant layers on the two adjacent auxiliary threads are connected through a triangular flame-retardant layer. The utility model has the advantages that: the first flame-retardant layer is designed on the main line, and the second flame-retardant layer and the triangular flame-retardant layer are arranged, so that the using amount of flame-retardant materials can be reduced, the cost is lower, the flame-retardant requirement can be met, and the design is more reasonable.
Description
Technical Field
The utility model belongs to the technical field of the sewing thread, especially, relate to a sewing thread.
Background
The sewing thread is required by the knitted clothing product, and can be divided into three types of natural fiber, synthetic fiber sewing thread and mixed sewing thread according to raw materials. With the development of the polyester industry, sewing threads are increasingly made of pure polyester fibers.
At present, flame-retardant sewing threads are available on the market, the sewing threads have good flame-retardant performance, and the conventional flame-retardant sewing threads are twisted by polytetrafluoroethylene threads and have good flame-retardant performance, but the threads have high cost.
SUMMERY OF THE UTILITY MODEL
The object of the utility model is to provide a sewing thread that can solve above-mentioned technical problem to above-mentioned problem.
In order to achieve the above purpose, the utility model adopts the following technical proposal:
a sewing thread comprises a main thread and a plurality of auxiliary threads twisted on the main thread, wherein a first flame-retardant layer is arranged in the circumferential direction of the main thread, two adjacent auxiliary threads are mutually leaned together, a second flame-retardant layer is arranged on an arc convex surface of the outer side of each auxiliary thread, which is radially far away from the main thread, and the second flame-retardant layers on the two adjacent auxiliary threads are connected through a triangular flame-retardant layer.
In one of the sewing threads described above, the first flame retardant layer has a thickness greater than that of the second flame retardant layer.
In the above one sewing thread, the number of the sub-threads is 9.
In one of the sewing threads described above, the circumferential length of the second flame-retardant layer is longer than the circumferential length of the sub-thread in which the second flame-retardant layer is not provided.
In one of the above sewing threads, the main thread diameter is larger than the sub thread diameter.
In the sewing thread, the first flame-retardant layer, the second flame-retardant layer and the triangular flame-retardant layer are all made of Teflon material layers.
Compared with the prior art, the sewing thread has the advantages that:
the first flame-retardant layer is designed on the main line, and the second flame-retardant layer and the triangular flame-retardant layer are arranged, so that the using amount of flame-retardant materials can be reduced, the cost is lower, the flame-retardant requirement can be met, and the design is more reasonable.
Drawings
Fig. 1 is a schematic view of a transverse cross-section structure of a sewing thread provided by the present invention.
In the figure, a main line 1, a sub-line 2, a first flame retardant layer 3, a second flame retardant layer 4, and a triangular flame retardant layer 5.
Detailed Description
The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
As shown in figure 1, the sewing thread comprises a main thread 1 and a plurality of secondary threads 2 twisted on the main thread 1, wherein the main thread 1 is made of polyester long fiber materials, and the secondary threads 2 are made of polyester long fibers and short fibers in a blending mode.
Both of the above threads are commercially available.
Next, the number of the sub-lines 2 is 9.
In addition, the diameter of the main wire 1 is larger than that of the sub-wire 2.
A first flame-retardant layer 3 is provided in the circumferential direction of the main yarn 1, and two adjacent sub-yarns 2 are laid against each other, i.e., twisted and pressed and laid against each other.
And a second flame-retardant layer 4 is arranged on the arc convex surface of the outer side of each secondary thread 2 which is radially far away from the main thread 1, because the two adjacent secondary threads 2 are mutually extruded and lean together, then the whole sewing thread is provided with the second flame-retardant layer 4, and the second flame-retardant layers 4 on the two adjacent secondary threads 2 are connected through a triangular flame-retardant layer 5.
The first flame-retardant layer 3, the second flame-retardant layer 4 and the triangular flame-retardant layer 5 are all made of Teflon material layers, and the Teflon material layers are processed in an infiltration or spraying mode.
When the secondary yarn twisting is not performed, the first flame-retardant layer 3 is firstly arranged on the primary yarn 1, and the secondary yarn twisting is performed after the drying.
Further, the thickness of the first flame retardant layer 3 of the present embodiment is larger than that of the second flame retardant layer 4.
Secondly, the circumferential length of the second flame-retardant layer 4 is longer than the circumferential length of the sub-line 2 where the second flame-retardant layer 4 is not provided.
By designing the first flame-retardant layer 3 on the main line 1 and the second flame-retardant layer 4 and the triangular flame-retardant layer 5, the using amount of flame-retardant materials can be reduced, the cost is lower, the flame-retardant requirement can be met, and the design is more reasonable.
The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein may be made by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
