本発明の織編物は、例えば以下の製造方法１または製造方法２により製造することができる。まず、製造方法１は、中間層用繊維として黒原着ポリエステル系繊維Ａを用い、表層用繊維および裏層用繊維として繊維Ｂを用いて、図１に織組織図が示されたダブルサテン組織に従い製織したダブルサテン組織織物、完全三重組織織物、表裏面の結接糸条として黒原着ポリエステル系繊維Ａが配された三層構造編物などを織編成する方法である。
The woven or knitted fabric of the present invention can be produced, for example, by the following
また、製造方法２は、黒原着ポリエステル系繊維Ａが芯部に位置し、一方繊維Ｂが鞘部に位置する芯鞘型複合糸を用いて、通常の織編組織（平織物などの単層組織でよい。）で製編織した織編物があげられる。
In addition, the
その際、芯鞘型複合糸としては、黒原着ポリエステル系繊維Ａが芯部に位置し、繊維Ｂが鞘部に位置する、インターレース加工糸やタスラン加工糸などの空気加工糸、複合仮撚加工糸、カバリング加工糸、合撚糸、意匠撚糸などが例示される。 At that time, as the core-sheath type composite yarn, the black original polyester fiber A is located in the core part, and the fiber B is located in the sheath part. Examples thereof include yarn, covering yarn, synthetic twisted yarn, and design twisted yarn.
かくして得られた織編物において、前記黒原着ポリエステル系繊維Ａが、織編物の全重量に対し２０〜８０重量％含まれることが好ましい。黒原着ポリエステル系繊維Ａの含有量が２０重量％よりも小さいと十分な遮光性が得られないおそれがある。逆に、黒原着ポリエステル系繊維Ａの含有量が８０重量％よりも大きいと、黒原着ポリエステル系繊維Ａが織編物の表面または裏面に沢山露出して外観が損われるおそれがある。 In the woven or knitted fabric thus obtained, it is preferable that the black original polyester fiber A is contained in an amount of 20 to 80% by weight based on the total weight of the woven or knitted fabric. If the content of the black original polyester fiber A is less than 20% by weight, sufficient light shielding properties may not be obtained. On the other hand, if the content of the black original polyester fiber A is greater than 80% by weight, the black original polyester fiber A may be exposed on the front or back surface of the woven or knitted fabric, and the appearance may be impaired.
また、本発明の織編物の表面および裏面において、下記式により求めた、織編物表面積に対する前記黒原着ポリエステル系繊維Ａの露出度が１０％以下であると、外観が損われず好ましい。
黒原着ポリエステル系繊維Ａの露出度＝（ＳＡ／（ＳＡ＋ＳＢ））×１００
ただし、ＳＡは表面（裏面）に露出した黒原着ポリエステル系繊維Ａの総面積（ｍｍ２）であり、ＳＢは表面（裏面）に露出した繊維Ｂの総面積（ｍｍ２）である。
Moreover, in the surface and the back surface of the woven or knitted fabric of the present invention, it is preferable that the degree of exposure of the black original polyester fiber A with respect to the surface area of the woven or knitted fabric obtained by the following formula is 10% or less because the appearance is not impaired.
Exposure degree of black original polyester fiber A = (SA / (SA + SB)) × 100
However, SA is the total area (mm 2 ) of the black original polyester fiber A exposed on the front surface (back surface), and SB is the total area (mm 2 ) of the fiber B exposed on the front surface (back surface).
また、本発明の織編物が織物組織を有する場合、優れた遮光性を得る上で下記式で定義するカバーファクター（ＣＦ）が３０００以上（好ましくは３５００〜４０００）であることが好ましい。また、遮光性としては、ＪＩＳ−Ｌ１０５５−Ａ法により測定した遮光率で９９．９９％以上であることが好ましい。
ＣＦ＝（ＤＷｐ／１．１）１／２×ＭＷｐ＋（ＤＷｆ／１．１）１／２×ＭＷｆ
ただし、ＤＷｐは経糸総繊度（ｄｔｅｘ）、ＭＷｐは経糸織密度（本／２．５４ｃｍ）、ＤＷｆは緯糸総繊度（ｄｔｅｘ）、ＭＷｆは緯糸織密度（本／２．５４ｃｍ）である。
When the woven or knitted fabric of the present invention has a woven structure, the cover factor (CF) defined by the following formula is preferably 3000 or more (preferably 3500 to 4000) in order to obtain excellent light shielding properties. Further, the light shielding property is preferably 99.99% or more in terms of the light shielding rate measured by the JIS-L1055-A method.
CF = (DWp / 1.1) 1/2 × MWp + (DWf / 1.1) 1/2 × MWf
However, DWp is the total warp fineness (dtex), MWp is the warp weave density (main / 2.54 cm), DWf is the total weft fineness (dtex), and MWf is the weft weave density (main / 2.54 cm).
なお、本発明の織編物には、常法の染色加工、アルカリ減量加工が施されてもよい。さらには、常法の吸水加工、撥水加工、起毛加工、紫外線遮蔽あるいは制電剤、抗菌剤、消臭剤、防虫剤、蓄光剤、再帰反射剤、マイナスイオン発生剤等の機能を付与する各種加工を付加適用してもよい。 The woven or knitted fabric of the present invention may be subjected to conventional dyeing processing and alkali weight reduction processing. Furthermore, functions such as conventional water absorption processing, water repellency processing, brushed processing, ultraviolet shielding or antistatic agent, antibacterial agent, deodorant agent, insect repellent agent, phosphorescent agent, retroreflective agent, negative ion generator and the like are added. Various processing may be additionally applied.
次に、本発明の繊維製品は、前記の織編物を用いて縫製された、カーテン、衣服、椅子被覆材、カーシート、傘地などの繊維製品である。かかる繊維製品は、前記の織編物を含んでいるので外観を損なうことなく遮光性に優れる。特に、傘地が好適であり、優れた遮光性を呈しながら、任意の色に着色可能である。 Next, the textile product of the present invention is a textile product such as curtains, clothes, chair covering materials, car seats, umbrellas, etc., sewn using the woven or knitted fabric. Since such a textile product contains the woven or knitted fabric, it has excellent light shielding properties without impairing the appearance.
