Description

A general-purpose continuously rotatable narrow-band fabric cable and its weaving method

technical field

The invention relates to a narrow-band fabric cable in the technical field of flexible cables, in particular to a general-purpose continuously rotatable narrow-band fabric cable and a weaving method. the

Background technique

The information clothing system is also called a wearable computer. It is a modular and miniaturized design of the computer according to its functional application. It is placed in different positions of the clothing, and each module is connected by a cable to realize the wearable computer. Among them, flexible cable technology is one of the key technologies for the development of wearable computers. It is to prepare traditional computer data cables and power cables into conductive cables, which are used to ensure the signal and energy transmission of various information processing devices connected to information clothing. And appropriately meet the comfort of the cable technology. The common flexible cable technology at this stage is mainly the narrow-width fabric weaving method, which is to use thicker data lines and power lines directly as warp yarns and interweave weft yarns in order to form narrow-width fabrics. The fabric prepared by the method has good electromagnetic shielding performance and good data transmission stability. In the process of use, it only needs to be cut off from the end face, and when sewing different patterns, it will not cause the conductive path to break. However, there is a fatal shortcoming in the application of narrow-width woven flexible cables, that is, overlapping will inevitably occur when turning, which will affect the appearance and comfort of clothing. However, the research on the design of the turning part of the narrow-band fabric is still rare at home and abroad. the

Detailed ways

Below in conjunction with specific embodiment, further illustrate the present invention. It should be understood that these examples are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the teachings of the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims of the present application. the

Embodiments of the present invention relate to a general-purpose continuously rotatable narrow-band fabric cable. As shown in FIG. Composition, the weft yarn is polypropylene fiber; the wire is interwoven with the weft yarn as a part of the warp yarn in order to become a part of the narrow belt and covered; the turning point of the fabric cable is introduced into the long weft yarn instead of the warp yarn to complete the turning of the yarn import. The reed of the fabric cable is 11 per reed, 10 chemical fibers plus one cable (the place ticked in the drawing). Plain weave is used for the selvedge, 2 reeds are used for each reed, and a 30*10.5 reed is used for the steel reed. The universal narrowband cable in this embodiment can be turned. The narrowband cable is a double-layer fabric with conductors sheathed on both sides. the

The sealing part at the turning point is sealed by heat-melting and bonding at high temperature, so as to prevent the yarn from falling off during the weaving process after turning. The narrow-band fabric cable is a flat cable composed of double-layer tissue-coated wires, which improves the fit between the connecting cable and the clothing, thereby improving the appearance and wearing comfort of the information clothing. The polypropylene fiber in the warp yarn is 1000 denier polypropylene fiber, and the weft yarn is 1000 denier polypropylene fiber. The polypropylene fiber has high strength and good wear resistance, and can withstand relatively large tension and friction during the remanufacturing process, and can completely cover the wire , and polypropylene fiber is a thermoplastic fiber, which can be applied to high temperature fusion bonding and is easy to seal. The wire is a copper wire with a cross-sectional area of ^0.12mm2 . Considering that the wire will buckle and protrude after turning, in order to prevent the wire from being exposed on the surface of the fabric, a copper wire with a cross-sectional area of ^0.12mm2 is selected. The fabric cable of the present invention is two types of woven four-core and eight-core cables, which can be mass-produced and meet the needs of various core types.

The weaving method of the present invention is illustrated by taking an eight-core cable as an example. the

①Weaving the straight cable at the front part of the turn. the

②Introduce long weft yarns whose total number is equal to the number of warp yarns, and at the same time remove the wires one by one and turn. the

In this embodiment, five long weft yarns are introduced at a time, and then the weft is beaten. Without changing the parameters of the machine, first six long weft yarns are introduced to make the selvedge yarn after turning, and then five are introduced at a time, and the first wire is pulled out from the back rest. Turn around, introduce five yarns again, repeat this for eight groups, and then introduce six yarns for selvedge yarn. the

③Cut off the warp yarn that is attached to the woven cloth body, remove it, and seal it. the

The method of cutting off the excess yarn part and sealing it is the method of heat and high temperature melting and bonding. Cut off the warp yarn on the cloth body, clamp the cut warp yarn with clips, and then heat and bond at high temperature. The sealing must be sealed to prevent the yarn from falling off during the weaving process after turning. the

④Threading and reeding the long weft yarn according to the parameters of the upper machine. the

Wear it from the front of the machine to the back of the machine. Put the long weft yarn into the heald frame and before the reed, fix the woven front part horizontally on the machine head, and then thread it into the reed tooth and heddle from front to back. The most important thing is to ensure that the long weft yarn is Do not twist or entangle when the fabric is buried, otherwise the subsequent weaving will not be able to open the fabric mouth, and continuous weaving at the turning will not be possible, forming a good transition. the

⑤ Fix the woven cloth body on the machine head. the

Clamp the cloth body at the machine head to keep the cloth body level and balanced on the ground. The cloth body must be kept in balance, so that the yarn in weaving can also be kept in balance, so that the weaving can go on normally. If the cloth body and the yarn are skewed, the opening will be unclear and the beating-up will not be possible. When the cloth body is in balance, the yarn can be tightened to give a certain tension. the

⑥ Weaving turning part

This step is the same as weaving the straight cable before turning, the only difference is that we must always pay attention to maintaining the balance of the cloth body and the yarn during the weaving process. the

It is not difficult to find that the present invention can be used as the connecting cable of each hard module in the information clothing system, the fabric has good electromagnetic shielding performance, and has good data transmission stability, and has strong practicability. At the same time, due to the soft and flat characteristics of the narrow-band fabric, it can realize the natural turning of the same plane especially at the turning point, which is of great significance for improving the wearing comfort of the information-based clothing system. the
