Abstract

The utility model belongs to the technical field of the sewing thread, especially, relate to a fire-retardant sewing thread and line book thereof. It has solved the high technical problem of prior art cost. A flame-retardant sewing thread comprises a main thread and a plurality of auxiliary threads twisted on the main thread, wherein a Teflon layer is respectively arranged on the surface of each auxiliary thread, and two adjacent auxiliary threads are leaned together through mutually matched contact surfaces. The utility model has the advantages that: the usage amount of the Teflon layer material can be reduced, and meanwhile, the main line can be sealed by utilizing a structure that the contact surfaces are leaned together, so that the protection effect on the main line can be improved, and the flame retardant effect is finally realized.

Description

Flame-retardant sewing thread and thread roll thereof

Technical Field

The utility model belongs to the technical field of the sewing thread, especially, relate to a fire-retardant sewing thread and line book thereof.

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.

Secondly, when the line was established on the core, interior line head was difficult fixed, leads to the wire winding efficiency lower.

SUMMERY OF THE UTILITY MODEL

The utility model aims at the above-mentioned problem, a can solve above-mentioned technical problem's a fire-retardant sewing thread is provided.

In order to achieve the above purpose, the utility model adopts the following technical proposal:

a flame-retardant sewing thread comprises a main thread and a plurality of auxiliary threads twisted on the main thread, wherein a Teflon layer is respectively arranged on the surface of each auxiliary thread, and two adjacent auxiliary threads are leaned together through mutually matched contact surfaces.

In the flame retardant sewing thread, the number of the sub-threads is 6-8 and the sub-threads are uniformly distributed on the circumference.

In the flame-retardant sewing thread, the main thread is made of polyester long fiber.

In the flame-retardant sewing thread, the secondary thread is made by blending polyester staple fibers and cotton fibers. The ratio of the two is 1: 3.

The utility model provides a fire-retardant sewing thread book, includes to roll up the core to and around establishing the above-mentioned fire-retardant sewing thread on rolling up the core, roll up core one end and be equipped with the end plate, a calorie of line mouth has been seted up to the other end terminal surface, the interior line head that fire-retardant sewing thread was rolled up in card line mouth in.

In the flame-retardant sewing thread roll, the thread clamping opening is internally provided with the viscose, and the inner thread head of the flame-retardant sewing thread roll is stuck by the viscose and fixed in the thread clamping opening.

The viscose is solid glue.

Compared with the prior art, the flame-retardant sewing thread and the thread roll thereof have the advantages that:

the usage amount of the Teflon layer material can be reduced, and meanwhile, the main line can be sealed by utilizing a structure that the contact surfaces are leaned together, so that the protection effect on the main line can be improved, and the flame retardant effect is finally realized.

The wire clamping opening can facilitate the fixation of the inner wire end so as to further improve the winding efficiency.

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 fig. 1 to 3, a flame retardant sewing thread comprises a main thread 1 and a plurality of sub threads 2 twisted on the main thread 1, wherein the main thread 1 is made of polyester long fiber material. The secondary thread 2 is made by blending polyester staple fibers and cotton fibers.

Preferably, the secondary wires 2 of the present embodiment have 9 and are circumferentially uniformly distributed.

The surface of each secondary line 2 is respectively provided with a Teflon layer 3, the Teflon layers 3 are attached to the surfaces of the secondary lines 2 through infiltration, two adjacent secondary lines 2 are leaned together through contact surfaces 20 which are mutually inosculated, and the two contact surfaces 20 on one secondary line 2 are distributed in an acute angle.

The structure of this embodiment can reduce the amount of teflon layer material used, and simultaneously, it can also play a sealing role to thread 1 to utilize the structure that contact surface 20 relies on together, also can improve the guard action to the thread, finally plays a fire-retardant role.

As shown in fig. 1-4, a fire-retardant sewing thread roll comprises a roll core 4 and the fire-retardant sewing thread wound on the roll core 4, wherein an end plate 40 is arranged at one end of the roll core 4, a thread clamping opening 41 is arranged at the end surface of the other end of the roll core, and an inner thread head of the fire-retardant sewing thread roll is clamped in the thread clamping opening 41.

The thread clamping opening 41 can facilitate the fixation of the inner thread end to further improve the winding efficiency, and secondly, a knotting point is arranged on the inner thread end, and the diameter of the knotting point is larger than the width of the thread clamping opening 41.

The width of the thread catching opening 41 is gradually reduced from the inner side of the winding core 4 to the outer side thereof, and the width of the minimum part of the thread catching opening 41 is equal to the thread diameter of the flame-retardant sewing thread.

Next, an adhesive is provided in the thread catching opening 41, and the inner thread of the flame retardant sewing thread roll is adhered and fixed in the thread catching opening 41 by the adhesive.
