Ultra high twist fiber manufacturing method

The present invention relates to a method of producing a fiber, and more particularly to a method for producing a fiber having an ultra high twist.

At present, the TPI used in the high-yield yarns developed by the industry is rarely more than 20.32. The fabrics made by such yarns have serious twisting and entanglement problems and difficulties in weaving, and are also detrimental to the quality of the products. In addition, if the industry's pure cotton fabrics are required to meet the general cool fabric requirements (contact temperature and cold sensitivity value Q-max>0.14), additional chemical agents for coolness processing are required, and there is no chemical agent for cooling processing. In the case of a cotton fabric which has a cool feeling effect, it is necessary to improve the manufacture and handling of high-twist fibers.

The main object of the present invention is to provide a method for producing fibers of ultra high twist.

To achieve the above object, the present invention provides a method for producing a fiber of ultra high twist, comprising: providing at least one single yarn, wherein the at least one single yarn has the same single yarn twist direction and a single yarn twist coefficient And tracking the at least one single yarn in a tracking direction, wherein the tracking direction is the same as the twist direction of the single yarn, and the tracking process is based on a tracking coefficient, wherein the single yarn coefficient And one of the tracking coefficients, the sum of the coefficients is between 7.0 and 9.5.

According to an embodiment of the invention, wherein the sum of the enthalpy coefficients is between 8.0 and 9.0.

According to an embodiment of the invention, the tracking coefficient is based on a tracking degree, and the tracking degree is between 25-35 TPI.

According to an embodiment of the invention, the tracking degree is between 30 and 35 TPI.

According to an embodiment of the invention, the single yarn twist direction and the tracking direction are both Z directions.

According to an embodiment of the invention, the at least one single-strand yarn is two.

According to an embodiment of the invention, the at least one single-strand yarn is made of cotton fiber material.

In order to enable the reviewing committee to better understand the technical contents of the present invention, the preferred embodiments are described below.

The invention adopts a compact spinning machine to carry out an ultra-high twist fiber manufacturing method, but the spinning machine is not the focus of the present case, so it will not be repeated. The part of the raw material, the invention adopts the three requirements of the fashion, the function and the environmental protection, and adopts the selected cotton fiber with long fiber length, high fineness and high strength, and according to the preferred embodiment, the raw material The choice of using higher cotton counts (70-100 sticks) of pure cotton fiber is more conducive to the high twisting process.

Please refer to FIG. 1 for a flow chart of the steps of the present invention.

Step 300: Providing at least one single yarn.

The focus of this case is that the single-strand yarns used for tracking have the same twist direction. According to the embodiment, the single-strand yarns are all in the Z-direction, and the number of single-strand yarns is mainly two, and the physical properties of the single-strand yarn are more Including a coefficient, will be related to the calculations described later.

Step 310: Tracking at least one single yarn in a tracking direction.

The process of tracking is to combine two single-strand yarns into one double-strand yarn. According to the embodiment, the tracking direction and the twist direction of the single-strand yarn are also in the Z-direction. The experimental content and calculation process will be detailed below:

The operating factors of the experiment of the present invention are the yarn count, the fiber twist, and the number of traces of the fiber, and the calculation formula of the twist coefficient used is:

捻 coefficient = twist (TPI) / (yarn count) ^1/2 .

The twist TPI is the twist per inch of each twist, in short, the number of twists per twist of the fiber. The twist of the crepe can be calculated by the above formula using the above formula, and the 捻 coefficient of the 捻 亦 is calculated by the above formula. After countless experiments, it is found that when the twist coefficient of the crepe twist coefficient plus the tracking coefficient is about 7.0-9.5, and the tracking degree is about 25-35 TPI (high-strength 捻), Q can be obtained. -max(W/cm ² ) ≧ 0.18 for the cooling result, the following data are two of the results of several experiments:

According to one embodiment, the 70 yarns used in the experiment have a twist of 31.26 TPI, and the twist coefficient = 31.26 / (70) ^{1/2 is} approximately equal to 3.74; if two single yarns having a twist coefficient of 3.74 are made with a twist of 25.71 TPI Chasing, the tracking coefficient = 25.71 / (70 ^{/ 2} ) ^1/2 is equal to 4.35, it should be noted that because of the double-share merger, in the formula calculation, the part of the count is divided by 2. According to the embodiment, the total number of turns is equal to the twist coefficient of the twisted yarn plus the tracking coefficient = 3.74 + 4.35 = 8.09. After the general processing and weaving finishing, the instrument measures the contact feeling of the warmth and the sense of Q-max (W/cm ² ) is about 0.181.

According to another embodiment, the 70 yarns used in the experiment have a twist of 35.3 TPI, and the twist coefficient = 35.3 / (70) ^{1/2 is} approximately equal to 4.22; if two twisted yarns having a twist factor of 4.22 are twisted at 27.56 TPI For the memorial, the tracking coefficient = 27.56 / (70/2) ^1/2 is equal to 4.66. It should be noted that because of the double-share merger, the part of the count is divided by 2 in the formula calculation. According to the embodiment, the total number of turns is equal to the twist coefficient of the twisted yarn plus the tracking coefficient = 4.22+4.66=8.88. After the general processing and weaving finishing, the instrument measures the contact cooling effect Q-max (W/cm ² ) is about 0.18.

According to still another embodiment, the 90 yarns used in the experiment have a twist of 34.25 TPI, and the twist coefficient = 34.25 / (90) ^{1/2 is} approximately equal to 3.61; if two twisted yarns having a twist factor of 3.61 are twisted at 34.19 TPI For the memorial, the tracking coefficient = 34.19 / (90/2) ^{1/2 is} approximately equal to 5.1, the total number of turns is equal to the twist coefficient and the tracking coefficient = 3.61 + 5.1 = 8.7, after general processing and weaving After finishing the processing, the instrument measures the contact cooling effect Q-max (W/cm ² ) of about 0.187.

The main effect of the fiber made by the fiber manufacturing method of the present invention is that it does not need to additionally add a chemical agent for processing coolness, and it can be brought into contact with the processing agent of the general processing woven fabric to have a contact feeling of warm feeling Q-max (W /cm ² ) ≧ 0.18, which is a property not currently available in commercially available cotton fabrics.

It should be noted that the above is only an embodiment, and is not limited to the embodiment. For example, those who do not depart from the basic structure of the present invention should be bound by the scope of the patent, and the scope of the patent application shall prevail.
