Description

[0002] Ramie Raw Material Manufacturing Methods For Fineness Type [0003]

More particularly, the present invention relates to a method for producing raw timbers by fineness, and more particularly, to provide timber timber raw materials by uniform cutting to have a constant length of fiber according to the fineness distribution of the timber timber, The present invention relates to a method for producing raw timbers of different sizes, which can improve the quality and tensile strength of a yarn spun by about 30% or more.

Representative bast fibers such as flax, ramie, hemp, jute, and kenaf are processed into spinning raw materials and mixed with spun yarn or other materials to form spun yarns. .

Despite its advantages as a natural fiber, it is not universally used due to its low stretchability, stiffness, easy creasing, surface brittle, high manufacturing cost, and it is used for high fashion products and functional products. .

Compared to other bast fiber materials, the ramie has a long staple length and fineness even in the raw material processed by the face application (refining and splitting process) It is believed that spinning yarn manufacture is possible.

However, up to now, general spinning techniques have been reported to produce thick yarns of about 30 yarns for blend yarns and less than 20 yarns for 100% wool spinning yarns.

Generally, in order to meet ideal spinning yarn manufacturing characteristics in cotton blend condition, the fiber length should be 250 ~ 600㎜, similar to or longer than cotton fiber, and the fineness should be in the range of 1.3 ~ 2.0denier (diameter 9 ~ 12㎛) Can not be manufactured.

According to the staple fiber spinning theory (based on the Martindale formula), the yarn evenness, which means yarn quality, is statistical meaning, indicating the thickness variation (CV%) in the length direction of the yarn, and the smaller the result, the more uniform quality .

In the case of linen yarn, the thickness variation (CV%) is a measure of yarn quality, which indicates that the tensile strength is increased by decreasing the weak point in the longitudinal direction by minimizing the change in yarn thickness.

Accordingly, the background art of the present invention is to develop a technique for uniformly maintaining the fineness and having a constant fiber length in the production of the cotton-like viscose raw material, so that it is possible to obtain a uniform yarn with high uniformity (CV%) and high tensile strength .

FIG. 1 is a flowchart of a method of manufacturing raw timber according to the present invention, FIG. 2 is a detailed flowchart of step S30, and FIG. 3 is a photograph showing an embodiment of step S30 in FIG.

As shown in FIGS. 1 to 3, the present invention provides a method for producing a mixed yarn with a fineness by finely dividing a filament yarn according to a fineness distribution according to the distribution of fineness at the time of a preliminary firing, The present invention relates to a method for producing raw timbers of fine timber which can improve the quality and tensile strength of timber spun yarn by about 30% or more.

In addition, the present invention provides a method of producing raw timbers of each fineness by individually providing raw timbers of each fineness, thereby increasing the tensile strength by reducing the weak points in the longitudinal direction by minimizing the change in the thickness of the yarns, / 1 > and more than three yarns can be produced.

The method of producing the raw material for each fineness is as follows.

Step S10: First, peel off the fleece, pass it through a rolling machine, and obtain a bundle of the fleece that gives flexibility and splitting effect.

More specifically, the dried fan is passed through a slotted rolling machine to separate the air holes and the skin, and then the hair is peeled to produce the ephemeral hair or the epilating hair is passed through the grooved rolling machine to impart flexibility and fibrillating effect.

Step S20: Remove foreign substances and some pectin present at the time of epilation and refine and bleach to dry.

The refining was carried out by adding 5 g / l of NaOH, 10 g / l of Na ₂ CO ₃ , 1 g / l of scouring agent, 1 g / l of penetration agent and 1 g / l of antioxidant, Bleaching treatment can be carried out by adjusting the ratio of the chemicals and cold water after secondary refining under the same conditions.

Step S30: The bundles are uniformly cut at a distance of 250 mm to 600 mm at the time of drying the dried tongue, thereby manufacturing a plurality of fancy bundles.

In this case, prior to the production of the ephemeral bundle, the surface fineness distribution and the monolayer of the bundle at the time of the ephemeral hair are measured for each virtual section to be cut.

In this case, the 31st step can reduce the virtual section error by length by classifying the ephemeris of 1.7m or less and the ephemeris of 1.7m or more among the ephemeris having 1.5m ~ 2m total length of ephemeris.

As shown in FIG. 3, the bundled ephemera bundle is divided into five virtual sections, and the surface fiber distribution and the monolayer are measured through an optical microscope to determine a cut section according to the fineness distribution.

In Fig. 3, it can be seen that the fineness of the root portion of the Taisho is thick and the fineness thereof is thinner toward the opposite side of the root.

Accordingly, the cut-off time can be selectively determined at intervals of 10, 20, 30, 40, 50, or 10 to 20, 30, and 40 to 50 according to the fineness distribution .

Step S40: Cut the cut bundles at uniform intervals of 25 mm to 40 mm and cut into the size of the surface yarn material.

Step S50: The raw timber of each fineness is prepared through a fibrillation process using a cut-and-dried machine.
The thus prepared raw material was added to the mixing process of the spinning process in accordance with the mixing ratio set in accordance with the surface of the spinning process to obtain 50 water samples (5% ramie), 40 water samples (10% ramie), 30 water samples (30% 55%) can be produced.

The resulting mixed silk spinning yarn has a uniform fineness distribution of the mixed yarn, thereby improving the quality and tensile strength of the conventional yarn spun yarn by about 30% or more. Also, the yarn having a yarn count of 40 & Manufacturing becomes possible.

The prepared raw material was added to the mixing process of the spinning process according to the mixing ratio set in accordance with the surface of the spinning process to obtain a mixture of 50 water (5% rhizome), 40 water (10% rhizome), 30 water (30% rhizome) %), And yarn quality evaluation and tensile strength evaluation were carried out.

(1) Yarn quality evaluation

The yarn quality evaluation of yarn yarns is generally carried out by measuring the mass unevenness (CV _m %) indicating the change in fiber thickness. Using a typical unevenness measuring device USTER Tester 4, the yarn speed is measured at a speed of 400 m / min under standard conditions And the time was 2.5 minutes.

(2) Tensile Strength Evaluation

Tensile strength was measured by using a constant rate of extensibility universal testing machine to determine the strength of the yarn according to KS K 0475-2011. The initial load was set at 7.4 cN (7.5 gf) for 20's, 4.9 cN (5 gf) for 30 s, 3.5 cf (3.5 gf) for 40 s, and 2.5 cf The distance was 200 mm, and each sample was tested 30 times and the average of the measured values was calculated.

The yarn quality test and the tensile strength test were performed on the four kinds of silk blend yarns manufactured by the present invention technique, and the results are shown in Table 1.

Seed Cotton / linen 50's Cotton / ramie 40's Cotton / Mosaic 30's Cotton / Moso 20's Moshi 5%
CM cotton 95% 10%
CM cotton 90% 30%
CM cotton 70% 55%
CD cotton 45% Unevenness (CV _m %) 20.1 16.4 13.9 21.4 Single yarn strength (cN) 14.7 18.7 29.4 36.3

As described above, the moxiblend yarn produced by the present invention showed a slightly higher unevenness than that of a general cotton yarn but no difference in the monofilament strength. This means that it can be utilized even in the same weaving and knitting conditions as the conventional spinning yarn.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. Accordingly, such modifications or variations are intended to fall within the scope of the appended claims.
