Description
Technical Field
The present invention relates to a polyester yarn, a woven or knitted fabric using the polyester yarn, and a uniform using the woven or knitted fabric. More particularly, the present invention relates to a polyester yarn capable of forming uniform excellent in colorfastness in severe industrial washing, and a woven or knitted fabric using the same.
Background
Washing of work clothes, unification of unification is often handled by industrial washing by washing operators. In particular, washing under severe conditions is required in order to remove stubborn stains and special stains.
In addition, as a recent trend, fashionable garments are also increasing in work clothes and uniforms. This trend is extended not only to commercial uniforms but also to uniforms of medical staff, caregivers (hereinafter, they are collectively referred to as "medical uniforms"), and the like. In particular, in medical uniforms, not only conventional white uniforms but also uniforms having the same shape and rich color changes with different colors, uniforms combining different colors at the positions of sleeves, collars, waist parts, and the like are often used, and various aspects are involved.
In uniforms which are fashionable and have a rich color change, woven or knitted fabrics of polyester fibers are generally used. The woven or knitted fabric of the polyester fiber is excellent in physical properties, can be dyed in a vivid color, and is suitable for a vivid and fashionable uniform. However, even in the case of woven or knitted fabrics using polyester fibers excellent in physical properties, there are cases where problems of color transfer due to washing occur in severe industrial washing. In general, color transfer is easily generated in the case of washing a dark uniform with a white or light uniform in the same bath.
Therefore, in industrial washing, washing is performed as a conventional operation after classification by color, darkness, and the like. However, it is also necessary to consider special stains attached during treatment, surgery, nursing, etc. or contamination caused by some pathogenic factors for medical uniforms, and there is a risk associated with classification operations in industrial washing sites for hygienic reasons.
For this reason, in general, with respect to industrial washing of medical uniforms, a special washing operator performs an operation of putting the medical uniforms, which are distributed from a medical institution or a nursing facility, into a washing machine to perform washing without classifying them. In this case, uniform of various colors and uniform of widely different shades are mixed in the washing bath, and a problem of color transfer due to washing frequently occurs due to severe conditions of industrial washing.
Generally, polyester fibers are dyed after being made into woven or knitted fabrics. In addition, medical uniforms which have a lot of color change and a small production lot are sometimes dyed after they are sewn. Disperse dyes and the like are used for dyeing woven fabrics or knitted fabrics or for dyeing sewn articles, but in consideration of color transfer caused by industrial washing, there are certain limitations in preparing dyes excellent in heat resistance and sublimation resistance, and it is difficult to cover a rich color change of medical uniforms.
Accordingly, as polyester fibers excellent in heat resistance and sublimation resistance as compared with dyed polyester fibers, there are dope-dyed fibers (hereinafter also referred to as "proto-dyed fibers"). The spun yarn is obtained by adding a coloring material such as a pigment to a molten polymer to color the polyester fiber, and spinning the fiber. As the pigment used, a pigment excellent in heat resistance and sublimation resistance is used, and thus, excellent in color fastness is obtained. It is considered that if the spun-dyed fiber is used for medical uniforms, it is possible to prevent color transfer due to severe industrial washing.
Disclosure of Invention
Problems to be solved by the invention
However, the spun yarn is lost during the color change of the spinning device during production, and it is practically necessary to produce the spun yarn in a large scale. Therefore, there is a problem that it is impossible to prepare a fibril capable of covering a large number of colors in correspondence with medical uniforms which are rich in color change and small in production lot.
Accordingly, an object of the present invention is to provide a polyester yarn which can exhibit a wide color change using a limited number of dyed fibers and is excellent in heat resistance and sublimation resistance, and which can produce uniform with little color transfer due to industrial washing, a woven or knitted fabric using the polyester yarn, and uniform using the woven or knitted fabric.
Means for solving the problems
In order to solve the above problems, the present inventors have found that the above object can be achieved by selecting, from among the spun fibers having a limited number of colors, a raw yarn (long fibers which are not processed) or a raw cotton (short fibers before spinning) which are excellent in heat resistance and sublimation resistance in particular, and using these raw yarns or raw cotton directly or in combination at a predetermined ratio, and have completed the present invention.
That is, according to the description of claim 1, the polyester yarn of the present invention is a polyester yarn for a woven or knitted fabric, characterized in that,
the polyester yarn contains only a raw liquid colored fiber whose sublimation fastness performance in the state of raw yarn or raw cotton is evaluated to be 4 to 5 or more in the judgment using JIS L0805 (gray scale spectrum for pollution),
the polyester yarn is obtained by using the dope-dyed fiber of one color or by using the dope-dyed fibers of a plurality of colors in combination and is configured to have a predetermined hue, chroma and lightness.
In addition, according to claim 2, the present invention is the polyester yarn according to claim 1, characterized in that,
regarding the sublimation fastness performance, a polyester white cloth was added to the raw yarn or raw cotton using a sweat tester specified in JIS L0854 (sublimation fastness test method), and a sublimation test was performed in dry heat at 180±2 ℃ for 10 minutes in a state where a pressure of about 12.5kPa was applied.
In addition, according to claim 3, the present invention is a polyester yarn as described in claim 1 or 2, characterized in that,
the single yarn fineness of the raw yarn or raw cotton is 2.222dtex or less.
In addition, according to claim 4, the woven or knitted fabric of the present invention is characterized in that,
the woven or knitted fabric is obtained by weaving or knitting the polyester yarn according to any one of aspects 1 to 3.
In addition, according to claim 5, the uniform of the present invention is characterized in that,
the uniform is obtained by sewing the woven fabric or knitted fabric described in the above-described scheme 4.
Effects of the invention
With the above configuration, the sublimation fastness performance of the polyester yarn of the present invention in the state of the raw yarn or raw cotton alone was evaluated as a liquid-dyed fiber (spun-dyed fiber) of 4 to 5 or more in the judgment using JIS L0805 (gray scale spectrum for pollution). The dope-dyed fiber of one color or the dope-dyed fiber of a plurality of colors is used in combination and is constituted so as to have a predetermined hue, chroma and lightness.
Thus, even if a limited number of primary fibers are used, a rich color change can be exhibited. Further, it is possible to provide a polyester yarn which has excellent heat resistance and sublimation resistance, and which can produce uniform with little color transfer due to industrial washing, because the sublimation fastness of the used spun fiber is 4 to 5 or more.

This can more specifically exert the above-described effects.
In addition, according to the above constitution, the single yarn fineness of the raw yarn or the raw cotton may be 2.222dtex or less. Thus, a thin and soft polyester yarn can be produced, and a uniform having lively, fashionable and rich color change can be provided.
In addition, according to the above constitution, the woven or knitted fabric of the present invention is obtained by weaving or knitting the polyester yarn. This can more specifically exert the above-described effects.
In addition, according to the above configuration, the uniform of the present invention is obtained by sewing the woven fabric or knitted fabric. Thus, a sorting operation at the time of industrial washing is not required to thereby reduce washing operations and reduce the risk of infection to operators.

Detailed Description
Hereinafter, the polyester yarn of the present invention, the woven or knitted fabric using the polyester yarn, and the uniform using the woven or knitted fabric will be described with reference to embodiments. The present invention is not limited to the following embodiments.
The polyester yarn of the present embodiment is used for woven or knitted fabrics. The polyester fibers constituting the polyester yarn may be long fibers or short fibers. In the case where the polyester fiber is a long fiber, a multifilament is formed. In the case where the polyester fiber is a staple fiber, a spun yarn is formed. The type of the polymer (polyester resin) used for the polyester fiber is not particularly limited, and may be polyethylene terephthalate, polybutylene terephthalate, polypropylene terephthalate, or other resins.
The single yarn fineness of the raw yarn (in the case of long fibers) or the raw cotton (in the case of short fibers) constituting the polyester yarn is not particularly limited, but a fiber which is thin to some extent is preferable in order to constitute a uniform of a lively and fashionable design. For example, the fineness of the single yarn is preferably 2.222dtex or less, and more preferably 1.6665dtex or less.
The polyester yarn of the present embodiment contains only the liquid-colored fibers (spun fibers). As described above, the spun yarn is a yarn obtained by adding a coloring material such as a pigment to a molten polymer, coloring the polymer, and spinning the colored polymer. That is, the polyester fiber used in the present invention is not a fiber obtained by dyeing after spinning, is not a fiber obtained by dyeing after weaving or knitting, and is not a fiber obtained by dyeing after sewing.
As the pigment for the proto-dyed fiber, a pigment excellent in heat resistance and sublimation resistance is used in the form of ultrafine particles. The present inventors have made various studies on particle diameters of pigments, addition amounts of polymers, and the like while taking account of single yarn fineness and physical properties of various pigments, and have selected polyester fibers which can be used after coloring of the present invention.
The selection of the proto-dyed fibers used in the present invention was evaluated by using sublimation fastness properties. As a condition of polyester yarn which does not undergo color transfer at the time of industrial washing of medical uniform, the present inventors found the sublimation fastness test method shown below.
First, a sublimation fastness test was performed in a state of raw yarn or raw cotton. In the sublimation fastness test, a sweat tester specified in JIS L0854 (sublimation fastness test method) was used. In this test machine, a composite test piece obtained by adding a polyester white cloth to a predetermined amount of raw yarn or raw cotton was sandwiched between stainless steel plates, and the test piece was fixed in a state where a pressure of about 12.5kPa was applied. The test machine in this state was placed in a dryer at 180.+ -. 2 ℃ with the composite test piece held in the vertical direction, and dry heat treated for 10 minutes. And immediately taking out the composite test piece after the drying treatment, spreading the raw yarn or the raw cotton and the polyester white cloth separately, and naturally cooling.
The evaluation of the sublimation test was performed by using the degree of contamination of the polyester white cloth added to the raw yarn or the raw cotton. Specifically, the contamination level was judged using JIS L0805 (gray scale spectrum for contamination). In the present invention, the contamination degree was evaluated as being at least 4 to 5. The degree of discoloration and fading in the sublimation test may be evaluated for the raw yarn or raw cotton. The present inventors found that the sublimation test method and the evaluation standard have a good correlation with the color transfer of an actual medical uniform due to industrial washing.
Next, the polyester yarn of the present invention is produced using the raw yarn or raw cotton of the polyester fiber selected in this way. In the case where the polyester fiber is a long fiber, the polyester long fiber yarn having a predetermined hue, chroma and lightness is formed by combining selected base yarns of one color or a plurality of colors by cabling. In the case where the polyester fiber is a staple fiber, the polyester staple fiber yarn having a predetermined hue, chroma and lightness is formed by combining raw cotton of one color or a plurality of colors selected by mixed spinning (hereinafter referred to as "blending").
The method of cabling and blending is not particularly limited, and may be carried out by a method generally carried out in polyester fibers. The thickness (fineness or count) of the polyester yarn produced by combining the raw yarn or the raw cotton is not particularly limited, and the polyester yarn may be configured in accordance with the design of the uniform as the final product. In the production of the polyester yarn, an elastic yarn may be produced by compounding an elastic yarn such as a polyurethane yarn with the polyester yarn.
An embodiment of the polyester yarn according to the present embodiment will be described with reference to the drawings. Fig. 1 is a front view (a) and a partial enlarged view (B) of one embodiment of the polyester yarn of the present invention. The polyester yarn 10 of fig. 1 is a polyester blended yarn obtained by blending three color polyester staple fibers 11, 12, 13 at a predetermined blending ratio. In the front view (a), a uniform color can be recognized as in the yarn dyed to one color. On the other hand, in the partial enlarged view (B), polyester staple fibers 11, 12, 13 of three colors are blended.
Fig. 2 is a cross-sectional view (C) of the polyester yarn 10. In the cross-sectional view (C), it can be seen that the polyester staple fibers 11, 12, 13 of three colors are blended. Since the three-colored fibers are uniformly blended in this manner, the polyester yarn 10 can be recognized as a uniform color as a yarn dyed to one color.
Next, the polyester yarn produced in this manner is woven or knitted to produce the woven or knitted fabric of the present invention. The weave of the woven fabric or the weave of the knitted fabric is not particularly limited, and may be configured according to the design of the uniform as the final product. The woven or knitted fabric manufactured in this manner is sewn to manufacture uniform. The design of the uniform to be manufactured is not particularly limited.
Next, the selection of the polyester fiber according to the present embodiment, the polyester yarn obtained by using the selected polyester fiber, and the woven or knitted fabric obtained by using the polyester yarn will be described with examples. The present invention is not limited to the following examples.
Examples (example)
In this example, evaluation and selection of polyester staple fibers, production of polyester yarns, and production and evaluation of polyester woven fabrics are described using raw cotton of polyester staple fibers.
Evaluation and selection of polyester Primary fibers
In this example, polyester protofilament fibers having different colors and single yarn fineness of 1.56dtex were spun. These polyester fibrils were then evaluated according to the sublimation test method and the evaluation criteria described above. Thirteen polyester proto-dyed fibers and evaluation results are shown in table 1. The hue, chroma and lightness of each protodyed fiber are expressed as L * a * b * The manner of each value of the color system is shown in table 1.
TABLE 1
In table 1, the results of sublimation tests on the raw cotton of thirteen polyester raw dyed fibers, except for three raw cotton numbers 10, 12, and 13, all of the pollution performance of the raw cotton were high evaluation results of 4 to 5 grades or more. On the other hand, the discoloration and fading properties were evaluated as high as 4 to 5 grades in all of the thirteen raw cottons. Thus, in this example, ten raw cotton numbers 1 to 9 and 11 were selected.
< production of polyester yarn >
Next, in this example, three kinds of polyester blended yarns obtained by blending the ten kinds of raw cotton were produced. In addition, as a comparative example, two polyester blended yarns were produced by blending unselected raw cotton. The fiber length of each raw cotton was 38mm, the count of the blended yarn was 28, and the spinning was performed by an air spinning machine. The blend ratios of the individual blend yarns are combined in accordance with the desired color of the polyester yarn to be produced.
TABLE 2
The spun yarns blended at the blending ratio shown in table 2 were not obtained by mixing a plurality of raw cotton materials of different colors, and could be evaluated as uniform colors like the yarn dyed to the target color.
Production and evaluation of polyester woven fabrics
Next, using the five kinds of blended yarns produced, fabrics were produced, respectively. The weave of each woven fabric was poplin, and the weave density was set to 115 warp yarns/inch and 65 weft yarns/inch. Next, these five woven fabrics (three examples and two comparative examples) were evaluated by the same sublimation test method and evaluation criteria as those of the raw cotton.
In addition, for five kinds of woven fabrics, a washing fastness test was performed using a representative industrial washing method performed on medical uniforms. First, a 10cm×20cm sample was taken from each woven fabric, and the short sides were sewn together with a polyester white cloth of the same size to prepare a composite test piece. As a washing test machine, a small-sized spin basket dyeing test machine (MINI-COLOR; manufactured by TEXAM technology, inc.) was used, and washing treatment was performed at a bath ratio of 1:8, a rotation speed of 45 times/min, and 80℃for 40 minutes. The composite test piece after the washing treatment was sufficiently washed with water, dehydrated and naturally dried, and then the discoloration and fading of the sample and the contamination of the polyester white cloth were evaluated in the same manner as in the sublimation test. It should be noted that the formulation of the industrial wash used employs two representative formulations. Wash test I is a wash without bleach and wash test II is a wash with bleach (sodium hypochlorite). The bath formulations for each washing method are shown in table 3.
TABLE 3
The evaluation results of the sublimation test and the evaluation results of the two washing tests are shown in table 4 for five kinds of woven fabrics (three of examples, two of comparative examples).
TABLE 4
In table 4, the evaluation of discoloration and contamination by sublimation test of woven fabrics nos. 1 to 3 of examples was good, whereby good results without contamination (color transfer) were obtained in any of the evaluation of discoloration and contamination by washing test I, discoloration and contamination by washing test II. In contrast, the woven fabrics of comparative examples nos. 4 and 5 were rated at 3 or 2 to 3 in contamination in the sublimation test, reflecting this, and contamination (color transfer) was observed in the contamination evaluation in the washing tests I and II.
In this embodiment, sewing to the uniform is not performed. However, according to the evaluation result of the washing fastness of the woven fabric, even when the woven fabric is used for producing uniforms, there is no fear of color transfer occurring in industrial washing of medical uniforms.
Therefore, according to the present invention, it is possible to provide a polyester yarn which can exhibit a rich color change using a limited number of dyed fibers and is excellent in heat resistance and sublimation resistance, and which can produce uniform with little color transfer due to industrial washing, a woven or knitted fabric using the polyester yarn, and uniform using the woven or knitted fabric.
In carrying out the present invention, the present invention is not limited to the above-described embodiments and examples, and various modifications are possible.
(1) In the above examples, ten raw cottons having good results of the sublimation test were selected from thirteen raw cottons. However, the present invention is not limited thereto, and raw cotton having good sublimation test results may be further added. Thus, a polyester yarn having a more abundant color change, a woven or knitted fabric using the polyester yarn, and a uniform using the woven or knitted fabric can be provided.
(2) In the above examples, spun yarns using polyester staple fibers were produced. However, the present invention is not limited thereto, and a polyester filament yarn may be produced using a polyester filament.
(3) In the above examples, woven fabrics using polyester yarns were manufactured. However, the present invention is not limited thereto, and a knitted fabric using polyester yarns may be produced.
