Description

Thermal Wire Weaving Machine {Thermogrid Loom}

The present invention relates to a hot wire weaving machine consisting of a weft feeder and a carrier needle for weaving the covered hot wire into the weft.

Textile fabrics are formed by supporting the threads from each other by weaving or knitting from the threads. Weaving and knitting methods in which the thread is guided up and down the adjacent yarns are different.

Weaving is a fabric in which warp yarns and weft yarns cross each other up and down to form a flat body of a certain width. It is woven with a loom, and there are various fabrics depending on the way of warp and weft crossing.

The woven fabric is a woven fabric made of icicles where the zigzag crosses the local sloping from side to side.

The main motion of the weaving process is shedding motion, which is a process of forming a tunnel called shed by separating the warp into two layers according to the fabric, and between the warp weaving the weft according to the fabric width. It consists of a picking motion to pass through, and a beating motion to push the weft thread through the opening to the front of the woven fabric as a body to complete the weft and warp tissue. In order to continue weaving, the fabric is wound on the rollers by removing the inclined beam from the weaving beam by taking out a certain amount of the fabric from the weaving part as required by the required speed and proper tension to the weaving part. Take-up is necessary.

The closing point is the rotation angle of the loom showing the time when the two up and down slopes are in a straight line. In general, the rotation angle of the loom is defined as 0 degrees when the body needle is made. In most weaving conditions, body needles occur after the closure.

Parameters for weaving include the elastic modulus of the yarn, the diameter of the yarn, the gap between the indentation, the basic tension of the warp, the tension of the cloth, the opening angle, and the friction between the warp and weft yarns.

When warp and weft are woven to form a tissue, there is a local curvature and weaving resistance is divided into elastic effect and friction effect. This elastic effect is mainly related to the bending effect. The coefficient of friction increases than in the case.

Needle loom is a kind of loom, and the weft thread is woven by penetrating the hole of the needle by the needle insertion method.

However, since the weft thread penetrates the needle hole, the weft yarn with a large elastic modulus and friction coefficient such as a heated heating wire is limited to weaving.

An object of the present invention is to solve the problem that the existing weft yarn is limited to weaving the weft yarn with a large elastic modulus and friction coefficient, such as a covered heating wire, which is a problem of the needle loom weaving through the needle hole.

In order to achieve the above object, the carrier needle has a pointed shape at one end of the elongated rod and two bearings 4b in the needle hole 4a on the pointed side, and the bobbin 12 for smooth weft supply. ) And weft feeder 20 is characterized in that it is configured.

The hot wire weaving machine according to the present invention is capable of weaving a weft yarn having a large coefficient of friction and elasticity such as a covered hot wire, a metal wire, and a coated yarn, and thus, the existing needle loom is not limited to the production of a narrow fabric such as a tape. There is an effect that can be activated by other applications to fabrics or functional fabrics.
