Description
本発明は、竹を原料とするレーヨン繊維と長繊維又は超長繊維な綿との混紡糸から作製される織物地又は編物地からなる衣料に関する。とくに、紫外線遮蔽性に優れ、肌に優しく、しかも寸法変化率が低く毛玉の発生が抑制された、竹を原料とするレーヨン繊維と長繊維又は超長繊維な綿との混紡糸から作製される織物地又は編物地からなる衣料に関する。 The present invention relates to a garment made of a woven fabric or a knitted fabric made from a blended yarn of rayon fibers made of bamboo and long fibers or ultra-long fibers. In particular, it is made from a blended yarn of rayon fiber and long fiber or ultra-long fiber cotton made from bamboo, which has excellent UV shielding properties, is gentle to the skin, and has a low dimensional change rate and suppressed generation of pills. The present invention relates to clothing made of woven fabric or knitted fabric.
消費者の製品に対する要求は多用化されており、例えば戸外で着用する衣料では紫外線遮蔽性に優れた衣料が求められている。
そこで、布帛に酸化チタンを含む樹脂をコーティングしたり、紫外線吸収剤及び／又は紫外線遮蔽剤を含有する樹脂を織物表面に被覆し（特許文献１、特許文献２）、あるいは繊維を形成するポリマー中に酸化チタンや酸化亜鉛などの紫外線遮蔽剤を練り込んでおき（特許文献３）、それら布帛あるいは繊維から紫外線遮蔽性に優れた衣料を作製する技術が報告されている。それら衣料は確かに紫外線遮蔽性は優れているが、衣料表面に存在する紫外線吸収剤及び／又は紫外線遮蔽剤が肌には優しくないとの不都合さが残るので、紫外線遮蔽性に優れ、しかも肌に優しい衣料の開発が望まれている。
Consumers' demands for products are diversified. For example, clothing that is worn outdoors is required to have excellent UV shielding properties.
Therefore, the fabric is coated with a resin containing titanium oxide, or the fabric surface is coated with a resin containing an ultraviolet absorber and / or an ultraviolet shielding agent (Patent Document 1, Patent Document 2), or in a polymer forming a fiber. A technique has been reported in which an ultraviolet shielding agent such as titanium oxide or zinc oxide is kneaded into the fabric (Patent Document 3), and an apparel excellent in ultraviolet shielding properties is produced from these fabrics or fibers. Although these clothes are certainly excellent in UV shielding properties, the disadvantage that UV absorbers and / or UV shielding agents present on the clothing surface are not gentle to the skin remains, so they are excellent in UV shielding properties and skin. Development of gentle clothing is desired.
一方、肌に優しい衣料としては、例えば木綿に代表される天然セルロース、又はビスコースに代表される再生セルロース等のセルロース系繊維を利用した衣料が知られており、現在でも多用されている。ところが、当該衣料は、皺になりやすくまた洗濯後に縮みやすい等の問題点がある。そこで、セルロース系繊維にポリエステル繊維などの合成繊維を混紡して作製した材料から衣料が開発されたが（例えば特許文献４）、たしかに、それら衣料の提供により前記問題点は解決されたが、今度は肌触りや風合いが劣るという問題が指摘されている。 On the other hand, as skin-friendly clothing, for example, clothing using cellulosic fibers such as natural cellulose typified by cotton or regenerated cellulose typified by viscose is known and is still widely used. However, the apparel is prone to wrinkles and shrinks after washing. Then, although clothing was developed from the material produced by blending a synthetic fiber, such as polyester fiber, with cellulose fiber (for example, patent document 4), the said problem was solved by provision of those clothing, but this time, Has been pointed out that the texture and texture are inferior.
さらに、繰返し使用や洗濯によっても、風合いを保持し、寸法変化が少なく、毛玉の発生も抑制された衣料は誰しも望むところであり、それらの点を満足する衣料を提供することが出来れば、大変意味のあることである。 Furthermore, anyone who wants clothing that retains the texture even after repeated use and washing, has little dimensional change, and that suppresses the generation of pills is desired, and can provide clothing that satisfies those points. It is very meaningful.
そこで、本発明の課題は紫外線遮蔽性に優れ、肌に優しい衣料を提供することにある。また、紫外線遮蔽性に優れ、肌に優しく、しかも、寸法変化が少なく、毛玉の発生も抑制され、風合いにも優れた衣料を提供することにある。 Then, the subject of this invention is providing the clothing which is excellent in ultraviolet shielding property and is kind to skin. Another object of the present invention is to provide an apparel that has excellent ultraviolet shielding properties, is gentle to the skin, has little dimensional change, suppresses the generation of pills, and has an excellent texture.
本発明者らは、前記課題を解決するために鋭意研究した結果、竹を原料とするレーヨン繊維と長繊維又は超長繊維な綿とから作製された混紡糸から作製される織物地又は編物地からなることを特徴とする衣料は意外にも前記課題が解決できるとの知見を得た。その知見を基にしてさらに研究を進め、遂に本発明を完成させた。 As a result of diligent research to solve the above problems, the present inventors have found that a woven fabric or a knitted fabric is produced from a blended yarn produced from rayon fibers made from bamboo and long fibers or ultra-long fibers. Surprisingly, the present inventors have found that the above-mentioned problem can be solved. Based on this knowledge, further research was conducted and the present invention was finally completed.
以下、本発明を説明する。
本発明でいう衣料は竹を原料とするレーヨン繊維と長繊維又は超長繊維な綿から構成される織物地又は編物地から作製される。
本発明で用いる竹は特に制限されない。日本で生育した竹材を使用できるし、中国や東南アジアの諸国で生育した竹材も使用できる。それら竹材の中では、とくに中国産の竹材が好ましい。竹の種類も特に制限されないのであって、例えば真竹や孟宗竹をはじめとして、篠竹、呉竹、女竹、蓬莱竹、支那竹等の竹を用いることができる。特に、真竹、孟宗竹、しかも中国で育った真竹、孟宗竹を用いると、繊維が強靱であり、品質の良い衣料を作製できるので有利である。
The present invention will be described below.
The clothing referred to in the present invention is produced from a woven fabric or a knitted fabric composed of rayon fibers made from bamboo and long fibers or ultra-long fibers.
The bamboo used in the present invention is not particularly limited. Bamboo materials grown in Japan can be used, and bamboo materials grown in China and Southeast Asian countries can also be used. Among these bamboo materials, Chinese bamboo materials are particularly preferable. The kind of bamboo is not particularly limited, and bamboo such as Shintake, Kuretake, Onnatake, Shochiku, and Chinatake can be used, including, for example, true bamboo and bamboo shoots. In particular, the use of true bamboo, scorpion bamboo, and true bamboo cultivated in China is advantageous because the fibers are strong and high-quality clothing can be produced.
これら竹を原料とした繊維であれば特に制限されないが、特にレーヨン繊維であることが好ましい。竹を原料とするレーヨン繊維は既に知られている。前記レーヨン繊維の繊維長は特に制限されない。また、前記レーヨン繊維の単繊維の繊度としては、０．９〜２０．０ｄｔｅｘであることが好ましく、１．０〜１０ｄｔｅｘであることがより好ましい。繊度が前記範囲を外れたときには、硬さや強度の点等で問題があり不都合である。 Although it will not restrict | limit especially if it is the fiber which used these bamboo as a raw material, It is especially preferable that it is a rayon fiber. Rayon fibers made from bamboo are already known. The fiber length of the rayon fiber is not particularly limited. The fineness of the single fiber of the rayon fiber is preferably 0.9 to 20.0 dtex, more preferably 1.0 to 10 dtex. When the fineness is out of the above range, there are problems in terms of hardness and strength, which is inconvenient.
前記レーヨン繊維としては、竹を原料とするアセテート、トリアセテート、精製セルロース、ビスコースレーヨン、及び、銅アンモニアレーヨン等の繊維が好ましい。これらは、１種単独で使用してもよく、２種以上を併用してもよい。 As the rayon fiber, fibers such as acetate, triacetate, purified cellulose, viscose rayon, and copper ammonia rayon made from bamboo are preferable. These may be used alone or in combination of two or more.
前記セルロースレーヨン繊維の製造方法としては、一般のレーヨン繊維と同様の製造方法が好適に挙げられる。例えば、ビスコースレーヨンは、竹を原料とするパルプをアルカリ及び二硫化炭素に反応させ、苛性ソーダに溶解して紡糸し、セルロースを凝固・再生することにより製造することができる。該ビスコースレーヨン、銅アンモニアレーヨン、アセテート、トリアセテート、及び、精製セルロースの製造方法は、すでに広く知られており、本発明ではその方法を適宜用いればよい。 As a manufacturing method of the said cellulose rayon fiber, the manufacturing method similar to a general rayon fiber is mentioned suitably. For example, viscose rayon can be produced by reacting pulp made from bamboo with alkali and carbon disulfide, dissolving it in caustic soda, spinning it, and coagulating and regenerating cellulose. Methods for producing the viscose rayon, copper ammonia rayon, acetate, triacetate, and purified cellulose are already widely known. In the present invention, these methods may be used as appropriate.
前記織物地又は編物地を構成する繊維として、長繊維又は超長繊維な綿の繊維を採用することに本発明の一つの特徴がある。本発明では長繊維又は超長繊維な綿であれば特に制限されず使用できる。その繊維長は平均値として２８ｍｍ以上であれば使用可能であるが、平均繊維長が３０ｍｍ以上である綿が好ましく、所謂超長繊維といわれる平均繊維長が３５ｍｍ以上であれば更に好ましい。平均繊維長の上限は特に限定されない。前記長繊維又は超長繊維な綿において、単繊維の繊度としては特に制限されないのであるが、例えば１．０〜１０．０ｄｔｅｘである繊維を用いることが好ましい。
本発明で用いる長繊維又は超長繊維な綿としては、例えば、中国、西印度諸島で生産される長繊維又は超長繊維な綿が好ましく、その中でも中国の新疆で生産される新疆綿が好ましい。

本発明では前記竹を原料とするレーヨン繊維と前記長繊維又は超長繊維な綿の繊維とを混紡し、糸を作製することに本発明の一つの特徴がある。原料とするレーヨン繊維と前記長繊維又は超長繊維な綿の繊維とを混紡する手段、方法は、本発明の所期の目的を達成することができるのであれば、特に制限されないのであって、例えば、竹を原料とするレーヨン繊維と前記長繊維又は超長繊維な綿の繊維とを調合し（調合工程）、前記調合処理物を梳毛カードにかけて篠状にし（カード工程）、篠を引き伸ばし、撚りをかけ（精紡工程）混紡糸を得る手段、方法を例示できるが、この方法に何ら限定されない。本発明では前記竹を原料とするレーヨン繊維の繊維長をできるだけ揃えておくと共に、前記繊維長に前記長繊維又は超長繊維な綿の繊維の繊維長を揃えるようにすると、前記調合工程やカード工程をより温和な条件で短縮化することが可能となり、開綿、打綿時の過度な綿の刺激を回避することが出来るので、有利である。例えば、竹を原料とするレーヨン繊維と前記長繊維又は超長繊維な綿の繊維とを人の手で混ぜ合わせ、操作しやすい程度の大きさに丸め込んで並べる工程（この工程を人工調合工程という）を前記調合工程の初めにおくことが有利である。繊維長を揃えておく程度は、用いる材料や作製しようとする衣料によって異なるのであり一概に規定することができないが、例えば、前記竹を原料とするレーヨン繊維の繊維長を±５％程度以下に揃えておくことが好ましく、±３％程度以下に揃えておくことがより好ましい。また、前記綿の繊維の平均繊維長を前記竹を原料とするレーヨン繊維の平均繊維長の±３％程度以下に揃えるようにすることが、優れた特性を有する衣料を作製できるという点で好ましい。 In the present invention, one feature of the present invention resides in that a yarn is produced by blending the rayon fiber made of bamboo as a raw material with the long fiber or the ultra-long cotton fiber. Means and method for blending rayon fibers as raw materials and the above-mentioned long fibers or ultra-long cotton fibers are not particularly limited as long as the intended purpose of the present invention can be achieved, For example, rayon fiber made from bamboo and the above-mentioned long fiber or ultra-long cotton fiber are prepared (preparation process), and the preparation process is applied to the eyelashes card to form a shino (card process). Means and method for obtaining a blended yarn by twisting (spinning process) can be exemplified, but the method is not limited to this method. In the present invention, the fiber lengths of the rayon fibers made from bamboo as a raw material are aligned as much as possible, and the fiber lengths of the long fibers or ultra-long cotton fibers are aligned with the fiber lengths, so that the blending process and card It is advantageous because the process can be shortened under milder conditions, and excessive cotton stimulation at the time of cotton opening and punching can be avoided. For example, a process of mixing rayon fibers made of bamboo and the above-mentioned long fibers or ultra-long cotton fibers by hand, rounding them up to a size that is easy to operate (this process is called an artificial blending process) ) At the beginning of the compounding step. The degree to which the fiber lengths are aligned varies depending on the material used and the clothing to be produced and cannot be specified in general. For example, the fiber length of the rayon fiber made from bamboo is about ± 5% or less. It is preferable to align, and it is more preferable to align to about ± 3% or less. In addition, it is preferable that the average fiber length of the cotton fibers is adjusted to about ± 3% or less of the average fiber length of the rayon fiber made of bamboo as a raw material because it is possible to produce a garment having excellent characteristics. .
