Description

Crimp measuring device

The present invention relates to a device for measuring the crimp property of a crimped yarn, and in particular to measure the length of the skein after a predetermined time after a load dial is placed on a sample that is hooked to a predetermined hook to measure crimpability. This is to reduce the deviation of the actual quality and analysis data, so that the quality of the yarn can be accurately evaluated before weaving during the development of high crimp yarn or the evaluation of flammable yarn.

At present, the development of technology that improves the feeling of wearing by using the high crimp yarns to show excellent stretch characteristics during fabric manufacturing is emerging in the textile manufacturers.

When weaving with various stretched yarns, the surface is smooth and lacks a sense of volume, so it is often flammable separately to impart crimping properties. do.

However, the crimpability measurement method of yarns known in the past consists of yarns in a state of constant denier (3000 deniers) for each variety, and then each load before and after heat treatment is under heavy load + super load (606g) The length of the skein under the middle (6g) is measured, and the method of obtaining data by a predetermined conversion formula is taken.

However, in this way, when winding around the winding reel of 1m circumference to form a standard denier of 3000 denier, when it is wound by a regular multiple, deviation from the standard denier occurs depending on the number of windings.

As a result, the elasticity and aftertaste that appear in the actual weaving process cause a significant difference from the measured value.

And the load correction according to this deviation requires the preparation of a very large number of load weights,

Since the load weight limited to a predetermined weight is used, the data is not fine and accurate, and the accuracy of the calculated data is lowered.

As a result, the deviation between the actual quality and the analytical data is large, and the quality of the yarn can not be accurately evaluated before weaving during the development of high crimp yarns or flammable yarns. Will be done.

The present invention is to solve the problems caused by the conventional crimp property measurement method as described above,

The present invention is to determine the crimp property by measuring the length of the skein after a predetermined time after hanging the load adjustment dial on the sample hanging on a predetermined hook to reduce the deviation of the actual quality and analytical data development of high crimp yarn or quality of false twisted yarn In order to evaluate the quality of yarn before weaving,

In order to achieve the above object, an example of the configuration of the crimp measuring apparatus of the present invention is to measure the crimp property by measuring the skein length after a predetermined time after applying a load adjusting dial to a sample that is caught on a predetermined hook. Referring to the configuration of the present invention in detail based on the accompanying drawings shown as follows.

By adjusting the height of the spring 13 and the hook 14 fixed therein by adjusting the dial knob 12 exposed to the outside of the case 15 fixedly installed on the base 11 A dial-type load control structure 10 to allow adjustment of the load imparted to (S);

A measurement scale 20 vertically entered in a state of being fixed to the base 11;

An upper support 30 which is horizontally rolled on the upper end of the measurement scale 20 and has a hook 31 for hanging a skein-shaped sample S on the bottom;

The load indicator 40 is electrically connected to a load cell (not shown) for measuring the load on the hook 31 of the upper support 30, and the load indicator 40 for displaying and displaying the measured value digitally is configured to be coupled to each other.

In order to measure the crimpability of the sample S using the apparatus of the present invention configured as described above, as shown in FIG. 1, the hook 14 of the dial-type load control structure 10 and the hook of the upper support 30 ( 31) hook the sample S formed in the shape of a skein, and then adjust the length of the spring 13 by using the knob 12 so that the hook 14 connected to the spring 13 is appropriately fitted to the sample S. After applying the tensile force (load) is to measure the crimp through all the conditions of the sample (S) required by the conventional measurement method.

In more detail,

The denier of the sample (S) was approached to the reference denier (3000 denier), and the actual denier was measured, and the calculated actual denier was multiplied by the superload + heavy load (0.202 g / denier) and the super load (0.002 g / denier). The load of the value is given to the sample (S) through the load control structure 10, respectively, and calculated by the following equation and calculated by the existing crimp measurement method.

Crimp property (%) = (L₂- L₃) / L₁ ＊ 100

※ L₁ is the sample length after 2 minutes after giving super load + heavy load to the sample.

※ L₂ is the length of the sample after 2 minutes of giving super load + heavy load after boiling water treatment (100 ℃ * 30 minutes).

※ L₃ is the length of the sample after 2 minutes after removing the heavy load (remaining only the super load) after boiling the sample (100 ℃ * 30 minutes).

Thus, by measuring the crimp property of the yarn by using the apparatus of the present invention, it is possible to accurately evaluate the quality of the yarn before weaving during development of high crimp yarn or evaluation of the quality of the twisted yarn by reducing the deviation between the actual quality and the analytical data.

Features and other advantages of the present invention as described above will become apparent from the embodiments described below.
