Description

A kind of wear-resistant composite sewing thread

Technical field

The utility model relates to sewing thread technical field more particularly to a kind of wear-resistant composite sewing threads.

Background technique

Sewing thread is line needed for being knitted clothes product, and sewing thread can be divided into natural fiber by raw material, synthetic fibers stitch Thread line and mixing sewing thread three categories.With the development of terylene industrial, sewing thread uses pure polyester fiber as the more next of its raw material It is more.Polyester fiber is a kind of synthetic fibers best in quality, high to suture strength obtained, is only second in all kinds of sutures Nylon wire occupies second, and will not reduce intensity when hygrometric state.Its washing shrinkage very little, is less than by after-contraction of being suitably formed 1%, therefore the stitching sewed can remain flat very beautiful, pucker-free.Wearability is only second to polyamide fibre, and regain is low, has good High temperature resistant, low temperature resistant, light resistance and water resistance.So polyester thread, in many occasions, is taken using extremely wide kind For cotton sewing thread.Polyester thread is widely used, can be used for the garment sewing of cotton fabric, chemical & blended fabric and blended fabric, it is also possible to In seam knitted outerwear.Special polyester thread or the excellent of shoes and hats leather industry uses line.Existing some terylene produced sewing thread knots Structure is single, and wearability is still to be improved, for this purpose, it is proposed that a kind of wear-resistant composite sewing thread solves problem above.

Utility model content

Single purpose of the utility model is to solve structure exists in the prior art, wearability is still to be improved Disadvantage, and a kind of wear-resistant composite sewing thread proposed.

To achieve the goals above, the utility model adopts the technical scheme that

Design a kind of wear-resistant composite sewing thread, including the first core wire and the second core wire, first core wire and the second core Line is opposite and twists to form complete main core line, is equipped with the first wearing layer on the outside of first core wire and the second core wire, and described the Successively winding is equipped with the first winding line, the second winding line, third and winds line, the first winding line, second on the outside of one wearing layer Winding line and third winding line are successively wrapped in the shape of a spiral on the outside of first wearing layer, the first winding line, second The outer wall of winding line and third winding line is fixed with the second wearing layer.

Preferably, first wearing layer and the second wearing layer are polytetrafluoroethylene (PTFE) structure.

Preferably, the quantity of first core wire and second core wire is two, and first core wire is that terylene is long Terylene long fibre structure that is fine or being twisted, second core wire is the quartz fibre structure that quartz fibre monofilament is twisted into, described The twist value of terylene long fibre structure is 3800-3850, and the twist value of the quartz fibre structure is 2500-3000.

Preferably, the first winding line 5 is bamboo charcoal fiber structure, and the second winding line is nylon fibre structure, institute Stating third winding line is polyester fiber structure, and the third winding line is by the blended system of 65% terylene short fiber peacekeeping, 35% cotton fiber At the nylon fibre model polyamide fibre 66.

Preferably, the first winding line, the second winding line, third winding line are helically wound by blended mode It is arranged on the outside of first core wire and second core wire.

The utility model proposes a kind of wear-resistant composite sewing thread, beneficial effect is: by the first core wire and second The mutual cooperation of core wire and its first wear-resisting interlayer of outside setting makes wear-resistant composite sewing thread promote certain wearability With certain high temperature resistance, the multifunctionality of increased wear-resistant composite sewing thread while energy, while being twined by first Coiling, the mutual cooperation of the second winding line, third winding line and the second wear-resisting interlayer, make wear-resistant composite sewing thread obtain wearability It further gets a promotion, is provided simultaneously with the characteristic of antibacterial, ventilating and stretch-proof, improves practical performance.

Detailed description of the invention
