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. In particular, the present invention relates to a polyester yarn capable of forming uniform having good stain fastness in severe industrial washing, and a woven or knitted fabric using the polyester yarn.
Background
Washing of work clothes, uniforms, and the like is often handled by industrial washing performed by a washing operator in a lump. In particular, washing under severe conditions is required to remove stubborn stains and special stains.
In addition, as a recent trend, fashionable clothes are also increasing in work clothes and uniforms. This trend is extended not only to business uniforms but also to uniforms for medical staff and care givers (hereinafter, these are collectively referred to as "medical uniforms"). In particular, there are many aspects related to medical uniforms, such as uniforms that have the same shape and different colors, and that are widely varied, and uniforms that have different colors combined at positions such as sleeves, collars, and waists, in addition to conventional white uniforms.
In fashionable uniforms that are rich in color variation, woven or knitted fabrics of polyester fibers are generally used. The woven or knitted polyester fiber has excellent physical properties, can be dyed to a vivid color, and is suitable for active and fashionable uniforms. However, even when a woven or knitted fabric of polyester fibers having excellent physical properties is used, there is a problem of color shift due to washing in severe industrial washing. In general, color transfer is easily produced in the case of washing a dark colored uniform with a white or light colored uniform in the same bath.
Therefore, in industrial washing, washing after classification by color, shade, and the like is performed as a normal operation. However, in medical uniforms, special stains adhering to the medical uniforms during treatment, surgery, care, and the like, or contamination due to some pathogenic factor must be considered, and for hygienic reasons, there is a risk associated with sorting operations in industrial washing sites.
Therefore, in the industrial washing of medical uniform, it is common to perform an operation in which a dedicated washing operator puts the medical uniform, which is delivered from a medical institution or a care facility, into a washing machine to wash the medical uniform, without classifying the medical uniform. In this case, uniforms of various colors or uniforms having different shades are mixed in the washing bath, and there is a problem that color shift due to washing frequently occurs due to severe conditions of industrial washing.
Generally, polyester fibers are dyed after being formed into woven or knitted fabrics. In addition, in some cases, the medical uniform, which has a large color change and is produced in a small lot, is dyed after being sewn. Although disperse dyes and the like are used for dyeing woven or knitted fabrics or dyeing sewn products, the provision of dyes having excellent heat resistance and sublimation resistance is limited in consideration of color shift caused by industrial washing, and it is difficult to cover a wide color change of medical uniforms.
Therefore, as a polyester fiber having excellent heat resistance and sublimation resistance as compared with a dyed polyester fiber, there is a dope-dyed fiber (hereinafter, also referred to as "as a" spun-dyed fiber "). The spun-dyed fiber is obtained by spinning after coloring a polyester fiber by adding a coloring material such as a pigment to a molten polymer. Since the pigment used is excellent in heat resistance and sublimation resistance, the pigment has excellent color fastness. It is considered that if the primary dyed fiber is used for medical uniforms, it is possible to prevent color shift caused by severe industrial washing.
Disclosure of Invention
Problems to be solved by the invention
However, the spun fibers are produced in large quantities because of the large loss of the spun fibers upon color change of the spinning device. Therefore, there is a problem that a mass-covered raw dyed fiber cannot be prepared corresponding to a medical uniform which is rich in color change and small in production lot size.
Accordingly, an object of the present invention is to provide a polyester yarn that can exhibit a rich color change using a greige fiber having a limited number of colors and is excellent in heat resistance and sublimation resistance so that uniform having little color shift due to industrial washing can be produced, a woven or knitted fabric using the polyester yarn, and uniform using the woven or knitted fabric, in response to the above-described situation.
Means for solving the problems
As a result of intensive studies to solve the above problems, the present inventors have found that the above object can be achieved by selecting a base yarn (unprocessed long fiber) or a base cotton (short fiber before spinning) which is particularly excellent in heat resistance and sublimation resistance from among base dyed fibers having a limited number of colors, and using the base yarn or the base cotton as it is or in combination with the base yarn or the base cotton at a predetermined ratio, and have completed the present invention.
That is, according to the description of the embodiment 1, the polyester yarn of the present invention is a polyester yarn for woven or knitted fabrics, characterized in that,
the polyester yarn comprises only spun-dyed fibers having a sublimation fastness property in the state of raw yarn or raw cotton which is evaluated to be 4-5 levels or more in judgment using JIS L0805 (Gray Scale Spectrum for staining),

The present invention is also directed to the polyester yarn according to claim 1, as described in claim 2,
regarding the sublimation fastness performance, a polyester white cloth was added to the base yarn or cotton using a sweat tester specified in JIS L0854 (dye fastness test method against sublimation), and a sublimation test was performed in dry heat at 180 ℃ ± 2 ℃ for 10 minutes while applying a pressure of about 12.5 kPa.
Further, according to the description of the embodiment 3, the present invention is the polyester yarn according to the embodiment 1 or 2, characterized in that,
the single yarn fineness of the raw yarn or raw cotton is below 2.222 dtex.
Further, according to the description of claim 4, the woven or knitted fabric of the present invention is characterized in that,

This can more specifically exhibit the above-described effects.
In addition, according to the above configuration, the single yarn fineness of the raw yarn or raw cotton may be 2.222dtex or less. Thus, a thin and flexible polyester yarn can be produced, and therefore, active, fashionable uniform with a wide variety of colors can be provided.
Further, according to the above configuration, the woven or knitted fabric of the present invention is obtained by weaving or knitting the polyester yarn. This can more specifically exhibit the above-described effects.
Further, according to the above configuration, the uniform of the present invention is obtained by sewing the woven fabric or the knitted fabric.

Detailed Description
The polyester yarn of the present invention, a woven or knitted fabric using the polyester yarn, and a uniform using the woven or knitted fabric will be described below 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 constituted. In the case where the polyester fiber is a staple fiber, a spun yarn is constituted. The kind of the polymer (polyester resin) used for the polyester fiber is not particularly limited, and may be polyethylene terephthalate, polybutylene terephthalate, polytrimethylene terephthalate, or other resins.
The fineness of the raw yarn (in the case of long fibers) or raw cotton (in the case of short fibers) constituting the polyester yarn is not particularly limited, but a fiber having a certain fineness is preferable in order to constitute an active and fashionable uniform. 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 includes only spun-dyed fibers (spun-dyed fibers). As described above, the spun-dyed fiber is obtained by adding a coloring material such as a pigment to a molten polymer, coloring the polymer, and then spinning the fiber. That is, the polyester fiber used in the present invention is not a fiber obtained by dyeing after spinning, a fiber obtained by dyeing after weaving or knitting, or a fiber obtained by dyeing after sewing.
As for the pigment for the as-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 the particle size of a pigment, the amount of a polymer to be added, and the like, while considering the fineness of a single yarn and physical properties of various pigments, and have selected a colored polyester fiber that can be used in the present invention.
The selection of the as-dyed fibers used in the present invention was evaluated using sublimation fastness properties. As a condition for the polyester yarn that does not undergo color shift upon industrial washing of medical uniforms, the present inventors have found a sublimation fastness test method shown below.
First, a sublimation fastness test is performed in the state of raw yarn or raw cotton. In the sublimation fastness test, a sweat tester specified in JIS L0854 (dye fastness test method against sublimation) was used. In this testing machine, a composite test piece in which a predetermined amount of raw yarn or raw cotton was added with polyester white cloth was sandwiched between stainless steel plates and 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 kept in the vertical direction, and dry-heat treated for 10 minutes. After the drying treatment, the composite test piece was immediately taken out, and the raw yarn or cotton and the polyester white cloth were separately spread and naturally cooled.
Evaluation of the sublimation test was evaluated by the degree of contamination of the polyester white cloth added to the base yarn or the base cotton. Specifically, the degree of contamination was determined using JIS L0805 (gray scale spectrum for contamination). In the present invention, the case where the degree of contamination is not less than 4 to 5 is evaluated as acceptable. The degree of discoloration and fading in the sublimation test may be evaluated for the base yarn or the base cotton. The present inventors found that the sublimation test method and the evaluation criteria had a good correlation with color shift due to industrial washing of an actual medical uniform.
Next, the polyester yarn of the present invention is manufactured using the raw yarn or raw cotton of the polyester fiber selected in this manner. When the polyester fiber is a long fiber, selected raw yarns of one color or a plurality of colors are combined by cabling to form a polyester long fiber yarn having a predetermined hue, chroma, and lightness. When the polyester fiber is a staple fiber, a polyester staple fiber yarn having a predetermined hue, chroma, and lightness is formed by combining selected raw cotton of one color or a plurality of colors by blend 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 may be configured in accordance with the design of the uniform as the final product. In addition, when the polyester yarn is manufactured, an elastic yarn may be formed by combining an elastic yarn such as a polyurethane yarn with the polyester yarn.
Here, 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 partially enlarged view (B) of one embodiment of the polyester yarn of the present invention. The polyester yarn 10 in fig. 1 is a polyester blended yarn obtained by blending polyester staple fibers 11, 12, and 13 of three colors at a predetermined blending ratio. In the front view (a), the same yarn dyed in one color can be recognized as a uniform color. On the other hand, in the partially enlarged view (B), the polyester staple fibers 11, 12, and 13 of the three colors are blended.
Fig. 2 is a sectional view (C) of the polyester yarn 10. In the cross-sectional view (C), it is also known that the polyester staple fibers 11, 12, 13 of the three colors are blended. Since the three-color fibers are uniformly blended in this manner, the polyester yarn 10 can be recognized as a uniform color as a yarn dyed in 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 knit weave of the knitted fabric is not particularly limited, and may be configured in accordance with the design of a uniform as a final product. In addition, the woven or knitted fabric manufactured in this manner is sewn to manufacture a uniform. The design of the uniform to be manufactured is not particularly limited.
Next, selection of the polyester fiber of the present embodiment, a polyester yarn obtained using the selected polyester fiber, and a woven or knitted fabric obtained using the polyester yarn will be described with reference to examples. The present invention is not limited to the following examples.
[ examples ]
In this example, evaluation and selection of polyester spun fibers, production of polyester yarns, and production and evaluation of polyester woven fabrics will be described using raw cotton of polyester staple fibers.
< evaluation and selection of polyester spun fibers >
In this example, polyester spun fibers having a single yarn fineness of 1.56dtex and different colors were obtained by spinning. Subsequently, these polyester-spun fibers were evaluated according to the sublimation test method and the evaluation criteria described above. Thirteen polyester spun fibers and the evaluation results are shown in table 1. The hue, chroma and lightness of each of the greige fibers are expressed by L*a*b*The mode of each value of the color system is shown in table 1.
[ Table 1]
In table 1, the sublimation test results of the raw cotton of thirteen types of polyester raw-dyed fibers were all high evaluation results of grade 4 to 5 or more in the contamination performance of the raw cotton except for three types of raw cotton numbers 10, 12, and 13. On the other hand, regarding the color changing and fading performance, the high evaluation results of 4-5 grades are obtained in all thirteen raw cottons. Thus, in the present example, ten types of raw cotton nos. 1 to 9 and 11 were selected.
Production of polyester yarn
Next, in this example, three polyester blended yarns obtained by blending ten kinds of selected raw cotton were produced. As a comparative example, two types of polyester blended yarns obtained by blending unselected raw cotton were produced. 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 respective blended yarns are combined in accordance with the desired color of the polyester yarn to be produced.
[ Table 2]
Each of the spun yarns blended at the blending ratio shown in table 2 was obtained by blending a plurality of different colors of raw cotton, and was not evaluated as a uniform color as in the case of the yarn dyed with the target color.
< production and evaluation of polyester woven Fabric >
Next, using the five manufactured blended yarns, a woven fabric was manufactured individually. The woven structure of each woven fabric was poplin, and the weaving density was set to 115 warps/inch and 65 wefts/inch. The five woven fabrics (three examples and two comparative examples) were evaluated by the same sublimation test method and evaluation standard as those of raw cotton.
In addition, the five-woven fabrics were subjected to a wash fastness test by a typical industrial washing method performed for medical uniforms. First, a 10cm × 20cm sample was taken from each woven fabric, and the short sides thereof were sewn to each other with a polyester white cloth of the same size to prepare a composite test piece. As the washing test machine, a compact rotary pod type dyeing test machine (MINI-COLOR; manufactured by TEXAM technology, Ltd.) was used, and washing treatment was carried out at a bath ratio of 1:8, a rotation speed of 45 times/min, and a temperature of 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 staining of the polyester white cloth were evaluated in the same manner as in the sublimation test. It should be noted that the formulations for industrial washing used are representative two formulations. Washing test I is a washing method without using a bleaching agent, and washing test II is a washing method with a bleaching agent (sodium hypochlorite). The cleaning bath formulation of each cleaning method is 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 woven fabrics (three examples, two comparative examples).
[ Table 4]
In table 4, evaluation of discoloration, fading, and staining was good in the sublimation test of the woven fabric nos. 1 to 3 of the examples, and thus good results were obtained without staining (color transfer) in both of the evaluation of discoloration, fading, and staining in the washing test I and the evaluation of discoloration, fading, and staining in the washing test II. In contrast, the woven fabric nos. 4 and 5 of the comparative examples were evaluated as 3-grade or 2 to 3-grade in the contamination in the sublimation test, and on the contrary, the contamination (color shift) was observed in the contamination evaluations in the washing tests I and II.
In this embodiment, sewing to the uniform is not performed. However, as is clear from the results of the evaluation of the wash fastness of the woven fabric, even when a uniform is produced using the woven fabric, there is no fear of color shift in industrial washing of medical uniform.
Therefore, according to the present invention, it is possible to provide a polyester yarn which can exhibit a rich color change using a greige fiber having a limited number of colors and is excellent in heat resistance and sublimation resistance so that uniforms having little color shift due to industrial washing can be produced, a woven fabric or a knitted fabric using the polyester yarn, and a uniform using the woven fabric or the knitted fabric.
In carrying out the present invention, the present invention is not limited to the above embodiments and examples, and various modifications are possible as follows.
(1) In the above examples, ten kinds of raw cotton having good results of sublimation tests were selected from thirteen kinds of raw cotton. However, the present invention is not limited thereto, and raw cotton having a good sublimation test result may be further added. Thus, a polyester yarn with a more abundant color change, a woven fabric or a knitted fabric using the polyester yarn, and a uniform using the woven fabric or the 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 to this, and a polyester long fiber yarn may be produced using a polyester long fiber.
