Description

  The present invention relates to a spun yarn, a fabric using polyphenylene sulfite, and clothing using the same.

  Polyphenylene sulfite (hereinafter referred to as PPS) is excellent in heat resistance and flame retardancy, and also in chemical resistance, and is therefore widely used mainly for industrial materials such as bag filters and scrims. On the other hand, since it is also known to have high heat retention, various attempts have been made so far as an autumn / winter material for clothing, but it is difficult to dye and has a weak light resistance, so it is suitable for outer use Is not very suitable.

  In addition, the general physical properties are very similar to those of polyethylene terephthalate-based polyester, so that there is a drawback that pilling is likely to occur, but because of its excellent chemical resistance, there is a problem that this pilling cannot be removed by alkali weight loss. It was. For this reason, it is not very suitable for knitting, and it is easy to generate pilling due to friction with the clothes worn inside as a fabric lining. Patent Document 1).

On the other hand, bundling type spun yarn is known as the untwisted type spun yarn, but the bundling part forms unevenness of the yarn as the yarn structure, so the fabric manufactured using that yarn is If anything, it is more suitable for spring / summer materials because it is more dry-touched than fabrics made using ring yarn, but it is not widely deployed as a fall / winter material.
JP 2005-179849 A

  The present invention provides a spun yarn that solves the above-mentioned problems and solves the pilling problem associated with PPS, and realizes a material suitable for autumn / winter use with a non-twisted spun yarn, and a fabric and clothing using the spun yarn To do.

In order to solve the above problems, the present invention has the following configuration.
(1) A spun yarn comprising 10% by weight or more of polyphenylene sulfite fiber having a single fiber fineness in a range of 0.5 dtex or more and 5.0 dtex or less, and is substantially untwisted.
(2) A fabric comprising the spun yarn according to (1) above, wherein the polyphenylene sulfite fiber mixing ratio is 10% by weight or more.
(3) A garment comprising the fabric described in (2) above.

  By using PPS that has been suffering from pilling without removing the fluff once formed because it is too good in chemical resistance, it can be made of spun yarn with substantially no twist. It is possible to obtain a fabric suitable for the pilling prevention effect while utilizing the heat retaining property. Further, by taking advantage of the high heat retaining property of PPS, it is possible to obtain a spun yarn suitable for autumn / winter use, which was a field where untwisted spun yarn is not good.

  The fiber used in the present invention is PPS having a single yarn fineness in the range of 0.5 dtex or more and 5.0 dtex or less. When fibers of less than 0.5 decitex are used, the cotton openability deteriorates. As a result, the passability in the card process, which is the initial stage of the spinning process, deteriorates, and the sliver quality deteriorates, resulting in a spun yarn with a lot of nep. It becomes a factor of quality deterioration. In the case of fibers exceeding 5.0 decitex, there is no problem that the fiber passes through the spinning process. However, since the untwisted yarn is harder than the ring spun yarn, the single fiber fineness is preferably not thicker than this.

  As a form of the yarn, it is necessary to be a non-twisted spun yarn. The reason is that ring spun yarn cannot twist the fluff that appears on the yarn surface no matter how high the number of twists. As a mode, a bundling type apparatus is preferably used. For example, a spinning method in which fluff on the surface of the yarn is twisted by MVS (MURATA VORTEX SPINNER) of Murata Machinery Co., Ltd. is preferable. Murata Machinery Co., Ltd. MJS (MURATA JET SPINNER) is also preferably used.

  The spun yarn of the present invention preferably contains 10% by weight or more of PPS. This is because if it is less than 10% by weight, the heat retaining effect may not be sufficiently exhibited. The upper limit of the mixing ratio is effective for preventing pilling in this thread form, and is not particularly limited and can be up to 100%.

  Further, the mixing ratio of PPS as a fabric is preferably 10% by weight or more based on the fabric. This is because if the amount is less than 10% by weight, the heat retaining property that can be experienced is not sufficiently developed. On the other hand, the upper limit is effective for preventing pilling in the above thread form, and is not particularly defined and can be up to 100%.

  The form of the fabric is preferably used as a woven fabric or a knitted fabric, but can also be used as a non-woven fabric. Specifically, a 100% Zokki knitted knitted fabric of 10% by weight PPS mixed non-twisted spun yarn or a knitted knitted fabric knitted / woven with other fibers using 10% by weight of 100% PPS untwisted spun yarn is used.

  By using the woven or knitted fabric thus obtained, it is possible to obtain clothing that is difficult to pill and has high heat retention.

  The cross-sectional shape of the PPS fiber and other fibers used in the spun yarn of the present invention had a round shape, a flat shape, a polygon shape including a triangle, a shape having a concave portion, a shape having a convex portion, or a hollow thereof. Any shape such as a cross-section may be used.

  Further, in the present invention, the fiber material in the case of blending, knitting, knitting, and the like, represented by polyethylene terephthalate, polytrimethylene terephthalate, polyester represented by polybutylene terephthalate, nylon 6, nylon 66, aramid, etc. Polyamide, acrylic fiber that is often used as an autumn / winter material, polylactic acid, which is attracting attention as a biodegradable material, polyethylene with high strength and chemical resistance, polyvinyl alcohol with excellent water solubility, and chemical resistance Synthetic fibers such as excellent fluororesins, polyvinyl chloride excellent in flame retardancy, polyurethane fibers excellent in stretchability, cellulosic fibers such as rayon, cupra and polynosic made from cellulose components such as wood and bamboo, Milk protein, peanut protein, soybean protein Regenerated fibers such as protein fibers, semi-synthetic fibers such as acetate, diacetate and triacetate, inorganic fibers such as glass and metal, and vegetable fibers such as cotton and hemp, wool, cashmere, alpaca, Natural fibers such as rabbit, silk and other moving substance fibers can be widely used.

  In addition, when blending the above materials, it is preferably in the range of 0.5 dtex or more and 5.0 dtex or less for the same reason as in the spinnability of the PPS of the present invention.

  In the case of knitting, knitting or arranging the single yarn or composite yarn not containing PPS using the above material and the untwisted spun yarn of the present invention, from the viewpoint of preventing pilling, these are also untwisted spun yarn rather than ring yarn. Is preferred.

  There is no particular limitation on the structure of the woven fabric, and it can be a patterned fabric using a special weaving machine such as dobby or jacquard, as well as Mihara's texture such as plain weave, twill weave, and satin weave. In addition, a woven fabric woven with a pile loom used for a car seat or the like may be used.

  The structure of the knitted fabric is not particularly limited, and may be any of a circular knitting, a flat knitting, and a warp knitting, and it is effective to use it for one of the front yarn and the back yarn. Also, pile knitting used for blankets and the like such as a Mayer knitting machine can be suitably used.

  In consideration of fluffing and pilling, if the density of the woven or knitted fabric is low, the yarns move freely so that the yarns that come into contact with each other rub against each other, and the fluffs rub against each other to cause pilling. However, in the present invention, since the yarn is originally bound, it is difficult to fluff even if they are rubbed together, so there is no need to increase or decrease the cover factor more than necessary.
