Abstract

The present invention relates to production of synthetic resin film yarn, in which during or after the production of synthetic resin mono yarn, synthetic resin mono yarn (2) of 0.15-0.3 mm diameter (W1) is press-processed by a press roller (10) to produce a synthetic resin film yarn (4) having a lateral width (W2) which is 2-7 times the diameter (W1) of the finished mono yarn (2) and tensile strength which is 1-1.8 times of a synthetic resin film yarn of equal denier rating due to the forging effect. As such, the present invention exhibits markedly higher tensile strength in comparison to the conventional synthetic resin film yarn of equal denier rating and also allows the unit production cost of the film yarn to be lowered.

Description

Synthetic resin film manufacturing method and manufacturing apparatus using mono yarn, and synthetic resin film yarn

The present invention relates to the production of synthetic resin film yarns, in particular, the method of manufacturing a synthetic resin film yarn for producing a synthetic resin film yarn having a higher tensile strength than a mono yarn yarn as well as a relatively high tensile strength compared to a film yarn of the same thickness and A manufacturing apparatus and the synthetic resin film company are related.

In general, synthetic film yarns are used for manufacturing various knitted fabrics such as light shielding nets, weeding nets or wrapping nets, packaging nets, construction nets, and the like.

The manufacturing process of the resin film company first melts the synthetic resin raw material and extrudes through a die to make a thin film of plate shape, cut the thin film into a number of strands while cooling the thin film, and then heat and stretch the cut film strands. As a result, the final synthetic resin film yarn is obtained.

Such synthetic resin film yarn has the advantage of increasing the density of the fabric when utilized in the knitting fabric. For example, when the light-shielding net is knitted with black synthetic resin film yarns, it is highly advantageous to secure the light-shielding rate compared to the light-shielding net using mono yarns due to high fabric density.

However, after obtaining the knitted fabric made of a weave with synthetic resin film yarn and using it in an external environment, the knitted fabric used in the external environment is a means of confining water due to the characteristics of the film yarn having the width of the knitted fabric. Due to this water weight, the crushing phenomenon often occurs, and the planting tears, such as to reduce the life of the knitted fabric.

Therefore, if there is a search for a method of manufacturing a film yarn that can be further reinforced with tensile strength on the basis of the same denier synthetic resin film yarn will be a great response from many people involved.

Furthermore, since the installation cost of the film yarn manufacturing apparatus for manufacturing a synthetic film yarn is approximately twice as expensive as that of the mono yarn manufacturing equipment, if a synthetic resin film yarn can be manufactured using a relatively inexpensive mono yarn manufacturing apparatus, Film production costs could be lowered.

lower rollers

12 and 14 at the top of the first and second

lower rollers

12 and 14. The press upper roll part 16 which makes (2) process with the synthetic resin film yarn 4 is provided.

The press upper roll portion 16 is arranged in a row of short rollers 16a, each of which can be accommodated in units of 1 to 20 units of synthetic resin mono yarns 2 so that all mono yarns passing through the press roller 10 receive uniform pressing force. Each press roller 16a is configured such that a press operation cylinder 18 is installed correspondingly.

The preferred number of mono yarns 2 accommodated in the short roller 16a is 5 to 10 in consideration of film yarn processing efficiency and uniform pressing force tolerance.

Since each press roller 16a is provided with a press operating cylinder 18, all of the mono yarns 2 passing through the film yarn processing press roller 10 are press-up roll units irrespective of their positions arranged left and right. It can be processed into a synthetic resin film 4 while receiving a uniform pressing force by (16).

The synthetic resin film yarn (4) thus processed has a left and right width (W2) that is 2 to 7 times the diameter width (W1) of the mono yarn (2), which is a yarn finished product, while the mono yarn (2) is thinly stretched to 0.15 to 0.27 mm. And, due to the forging effect by the pressing force by the film roller processing press roller 10 may have a higher tensile strength than the mono yarn (2) used. And, compared to the same denier synthetic resin film yarns will have a tensile strength of 1 ~ 1.8 times.

Press roller 10 for processing the film yarn according to an embodiment of the present invention by adjusting the pressing force according to the use of the synthetic resin film yarn (4), even though the same denier thickness of the width control or the control of the tensile strength of the present invention (W2) ) And tensile strength range. For example, in the case of black synthetic resin film yarn 4, which should have good shading rate, by increasing the pressing force of the press roller 10 to make the film thickness thin, the yarn width of the film yarn is widened within the range of 0.3 to 2.1 mm (W2). In addition, in the case of the synthetic resin film yarn 4, which should have good tensile strength, the pressing force of the press roller 10 is lowered to narrow the yarn width within the range of 0.3 to 2.1 mm in the left and right width W2, and instead, the film thickness is thickened.

In addition, 150-200 denier-type synthetic resin film yarn, which is almost impossible to make with existing synthetic resin film yarn manufacturing equipment, can be easily manufactured by changing the thickness of mono yarn, and thus, when a tight telescopic fabric such as a mosquito net is squeezed, the space required for the mosquito net It can be manufactured very lightly and inexpensively while maintaining the density.

5 is a photograph showing a representative example of manufacturing a synthetic resin film yarn 4 using a mono yarn (2) as a yarn according to an embodiment of the present invention, 240 denier thickness, 450 denier thickness, 600 denier thickness Film yarns 4.

6 is an example photographic view of a knitted fabric knitted using a synthetic resin film yarn 4 prepared according to an embodiment of the present invention, and the exemplary synthetic resin film yarn 4 of FIG. 6 is inclinedly supplied to a knitting machine 30. The synthetic resin mono yarn is made by processing the press roller 10 of the present invention.

FIG. 7 is an exemplary photographic view of a knitting net fabricated after processing a part of a synthetic resin mono yarn and a mono yarn of the remaining portion to become a synthetic film yarn, in which the right side of the picture is knitted with mono yarn and the left side of the picture is knitted with film yarn One part.

As can be seen in Figure 7, it can be seen visually that the knitting portion by the film yarn is much higher density than the portion knitted by the mono yarn.
