Abstract
Description
本発明は、薄地の編地等の通気性を有する布帛に対して通気性を抑えた防風性を付与する布帛の加工方法に関する。 The present invention relates to a method for processing a fabric that imparts a windproof property with reduced air permeability to a fabric having air permeability such as a thin knitted fabric.
衣服等に用いられる布帛では、身体に密着させて着用するために伸縮可能な薄地の編地が使用されたり、ファッション性を高めるために目の粗い織地が使用されることがあるが、こうした布帛では通気性が高くなって保温効果が低下するようになる。そのため、外気温や風の影響により体感温度が低下しやすくなり、着用感が悪化する。 In fabrics used for clothes and the like, thin knitted fabrics that can be stretched to be worn in close contact with the body may be used, or woven fabrics with coarse eyes may be used to enhance fashionability. Then, the air permeability becomes high and the heat retaining effect is lowered. For this reason, the sensible temperature is likely to decrease due to the influence of the outside air temperature and the wind, and the wearing feeling is deteriorated.
通気性の高い布帛に対しては、布帛表面に樹脂コーティングすることで通気性を抑える防風性の付与加工を行うことが提案されている。例えば、特許文献１では、縦方向及び横方向に伸縮性を有する伸縮性生地よりなる衣服において、合成樹脂のダイレクトコーティング加工により伸縮性生地に防風性皮膜を形成した点が記載されている。 For fabrics with high air permeability, it has been proposed to perform a windproof imparting process that suppresses air permeability by resin coating on the fabric surface. For example, Patent Document 1 describes that in a garment made of a stretchable fabric having stretchability in the vertical and horizontal directions, a windproof film is formed on the stretchable fabric by direct coating processing of a synthetic resin.
また、布帛に用いる糸又は布帛の織編組織に関して防風性を付与するものに改良することが提案されている。例えば、特許文献２では、緯糸として弾性糸を１．５倍から５．０倍に伸長した状態で合成繊維の嵩高捲縮加工糸と複合してなる伸縮弾性複合糸をコース方向の編目間に挿入して編成され、編目内で編地空隙を十分塞ぐ程度に伸縮弾性複合糸が拡がった状態に扁平化されている緯糸挿入丸編地が記載されている。また、特許文献３では、沸水収縮率ＳＨＷが負である実質的に自発伸長能を有するポリエステルマルチフィラメント糸を少なくとも１種類以上含むポリエステル異収縮混繊マルチフィラメント糸を経糸及び／又は緯糸に使用してカバーファクター（ＣＦ）が２２００〜４０００となる条件で製織し、次いでアルカリ減量処理を施した後、少なくとも織物の片面に樹脂をコーティングし、フラジール法による通気度が１０ｃｃ／ｃｍ2／ｓｅｃ以上の織物とするコーティング布帛の製造方法が記載されている。 In addition, it has been proposed to improve the yarn used for the fabric or the woven or knitted structure of the fabric to impart windproof properties. For example, in Patent Document 2, an elastic elastic composite yarn obtained by combining an elastic yarn as a weft with a bulky crimped yarn of synthetic fiber in a state where the elastic yarn is extended from 1.5 times to 5.0 times is provided between the stitches in the course direction. There is described a weft-inserted circular knitted fabric that is knitted by insertion and flattened in a state in which the elastic elastic composite yarn is expanded so as to sufficiently close the knitted fabric gap in the stitch. Further, in Patent Document 3, a polyester different shrinkage mixed multifilament yarn containing at least one polyester multifilament yarn having a spontaneous boiling ability and having a negative boiling water shrinkage ratio SHW is used for warp and / or weft. After weaving under the condition that the cover factor (CF) is 2200 to 4000, and then performing alkali weight loss treatment, at least one side of the woven fabric is coated with resin, and the air permeability by the Frazier method is 10 cc / cm 2 / sec or more. A method for producing a coated fabric as a woven fabric is described.
通気性の高い布帛に対して、上述したように、布帛表面に樹脂コーティングすることで通気性を抑える防風性の付与加工を行うことは、防風性は向上するものの樹脂コーティングにより布帛の風合いが硬くなる欠点がある。特に、目の粗い編地の場合には、防風性を付与するために高濃度で樹脂コーティングを行う必要があり、風合いが硬くなって編地本来の特性が失われてしまう。 As described above, applying a windproof property that suppresses air permeability by coating the surface of the fabric with a resin on a highly breathable fabric improves the windproof property, but the texture of the fabric is hardened by the resin coating. There are disadvantages. In particular, in the case of a knitted fabric with coarse meshes, it is necessary to perform resin coating at a high concentration in order to impart windproof properties, and the texture becomes hard and the original characteristics of the knitted fabric are lost.
また、布帛に用いる糸又は布帛の織編組織に関して防風性を向上するように改良することは、布帛の製造に対して技術面及びコスト面で様々な制約を受けることになり、汎用性に乏しい布帛しか得ることができない。 Further, improving the windproof property with respect to the yarn used in the fabric or the woven or knitted fabric of the fabric is subject to various restrictions in terms of technology and cost with respect to the production of the fabric, and lacks versatility. Only fabric can be obtained.
そこで、本発明は、布帛に対して風合いを損なうことなく防風性を付与加工することができる布帛の加工方法を提供することを目的とするものである。 Then, this invention aims at providing the processing method of the fabric which can provide a windproof property without impairing a texture with respect to a fabric.
本発明に係る布帛の加工方法は、高分子材料を含み粘度２，０００ｍＰａ・ｓ〜３０，０００ｍＰａ・ｓに調製した捺染糊を、１インチ当りのメッシュ数が２０メッシュ〜５００メッシュのロータリスクリーン捺染機により塗糊量１０ｇ／ｍ2〜１００ｇ／ｍ2で布帛の片面に印捺して乾燥させる付与工程と、前記捺染糊が付与された前記布帛をカレンダー加工により圧縮加熱する処理工程とを備え、前記布帛に通気性を抑えた防風性を付与することを特徴とする。さらに、前記捺染糊は、前記高分子材料を２重量％〜３０重量％含むことを特徴とする。さらに、前記カレンダー加工は、加熱温度１２０℃〜２５０℃で処理することを特徴とする。さらに、前記布帛が吸水性を有する場合に、前記付与工程の前に前記布帛の表面を吸水阻害処理することを特徴とする。さらに、前記布帛が撥水性を有する場合に、前記付与工程において前記捺染糊に浸透剤を混合して印捺することを特徴とする。 The fabric processing method according to the present invention is a rotary screen printing method in which a printing paste containing a polymer material and having a viscosity of 2,000 mPa · s to 30,000 mPa · s has a mesh number of 20 to 500 mesh per inch. comprising a grant drying and press mark on one side of the fabric in Nurinori weight 10g / m 2 ~100g / m 2 , and a processing step of compressing and heating by calendering the cloth the printing paste has been applied by the machine, The fabric is imparted with windproof properties with reduced breathability. Further, the printing paste includes 2% to 30% by weight of the polymer material. Further, the calendering is performed at a heating temperature of 120 ° C. to 250 ° C. Further, when the fabric has water absorption, the surface of the fabric is subjected to water absorption inhibition treatment before the applying step. Further, when the fabric has water repellency, printing is performed by mixing a penetrant with the printing paste in the applying step.
上記のような構成を有することで、高分子材料を含む捺染糊をロータリスクリーン捺染機により印捺してカレンダー加工により圧縮加熱するので、高分子材料が布帛表面に均一に拡がって防風性を向上させるとともに布帛の風合いを維持することができる。 By having the configuration as described above, printing paste containing a polymer material is printed by a rotary screen printing machine and compressed and heated by calendering, so that the polymer material spreads uniformly on the fabric surface and improves windproof properties. At the same time, the texture of the fabric can be maintained.
本発明に係る加工処理を施す布帛としては、レーヨンに代表される再生繊維、綿に代表される天然繊維、アセテート等の半合成繊維、ポリエチレンテレフタレートに代表されるポリエステル系合成繊維、ナイロンに代表される脂肪族ポリアミド系合成繊維等の吸水加工及び撥水加工が可能なすべての繊維あるいはこれらの混合繊維を用いた薄地の布帛が挙げられる。そして、織物、編物又は不織布等いずれの布帛にも適用することができ、特に限定されることはない。 Examples of the fabric subjected to the processing according to the present invention include recycled fibers typified by rayon, natural fibers typified by cotton, semi-synthetic fibers such as acetate, polyester-based synthetic fibers typified by polyethylene terephthalate, and nylons. For example, all the fibers that can be water-absorbing and water-repellent, such as aliphatic polyamide synthetic fibers, or a thin fabric using a mixed fiber thereof. And it can apply to any fabrics, such as a woven fabric, a knitted fabric, or a nonwoven fabric, and it does not specifically limit.
布帛の片面に対し、高分子材料を含む捺染糊をロータリスクリーン捺染機により全面に印捺して乾燥させる付与工程を行う。付与工程に用いられる高分子材料としては、例えば、アクリル系樹脂、ポリウレタン系樹脂、シリコン系樹脂が挙げられ、これらの合成樹脂のうち複数を混合したものを用いてもよい。 On one side of the fabric, an applying step is performed in which a printing paste containing a polymer material is printed on the entire surface by a rotary screen printing machine and dried. Examples of the polymer material used in the application step include acrylic resins, polyurethane resins, and silicon resins, and a mixture of a plurality of these synthetic resins may be used.
捺染糊には、高分子材料を２重量％〜３０重量％を添加する。捺染糊の粘度は、２，０００ｍＰａ・ｓ〜３０，０００ｍＰａ・ｓに調整するとよく、より好ましくは、５，０００ｍＰａ・ｓ〜２０，０００ｍＰａ・ｓに調整するとよい。２，０００ｍＰａ・ｓより粘度が小さくなると、印捺処理を行う場合に布帛表面から捺染糊が内部に浸透しやすくなり、十分な防風効果を得ることができず、また、風合いの硬粗化も生じる。粘度が３０，０００ｍＰａ・ｓを超えると、メッシュから十分な塗湖量を印捺することができなくなり、洗濯耐久性の低下も生じる。粘度の調整は、一般に増粘剤と称される薬剤で調整することができる。 2 wt% to 30 wt% of the polymer material is added to the printing paste. The viscosity of the printing paste may be adjusted to 2,000 mPa · s to 30,000 mPa · s, more preferably 5,000 mPa · s to 20,000 mPa · s. When the viscosity is lower than 2,000 mPa · s, the printing paste is likely to penetrate into the interior from the fabric surface when performing the printing process, and a sufficient windproof effect cannot be obtained, and the texture becomes hard and rough. Arise. When the viscosity exceeds 30,000 mPa · s, it becomes impossible to print a sufficient amount of coating lake from the mesh, resulting in a decrease in washing durability. The viscosity can be adjusted with a drug generally called a thickener.
また、撥水性の高い布帛の場合には、印捺処理の際に捺染糊が布帛表面に拡がらずに水滴状に付着するため、捺染糊に予め浸透剤を加えておくとよい。浸透剤としては、布帛表面に捺染糊を拡げることができる程度に浸透効果を生じるものであればよく、例えば、界面活性剤、ＩＰＡ（イソプロピルアルコール）、ブチルセロソルブといったものが挙げられる。浸透剤の配合割合は、布帛の撥水性に応じて適宜設定すればよく、捺染糊が布帛表面全体に拡がるように添加すればよい。 In the case of a fabric having high water repellency, the printing paste is not spread on the surface of the fabric during the printing process and adheres in the form of water droplets. Therefore, a penetrant may be added to the printing paste in advance. Any penetrating agent may be used as long as it produces a penetrating effect to such an extent that the printing paste can be spread on the fabric surface. Examples thereof include surfactants, IPA (isopropyl alcohol), and butyl cellosolve. The blending ratio of the penetrant may be appropriately set according to the water repellency of the fabric, and may be added so that the printing paste spreads over the entire surface of the fabric.
なお、捺染糊には、浸透剤以外にも、紫外線吸収剤、抗菌剤、消臭剤、蓄熱加工剤、光触媒、シリカ等の機能加工剤を必要に応じて添加することもできる。 In addition to the penetrating agent, a functional processing agent such as an ultraviolet absorber, an antibacterial agent, a deodorant, a heat storage processing agent, a photocatalyst, or silica can be added to the printing paste as necessary.
高分子材料を含む捺染糊を印捺するロータリスクリーン捺染機としては、例えば、円筒状スクリーン版を用いた装置が挙げられるが、これ以外の公知のロータリスクリーン捺染機を用いてもよく、特に限定されない。円筒状スクリーン版を用いた装置は、金属製の円筒状スクリーン版の内部にスキージを配置し、スキージの先端部が円筒状スクリーン版の内周面に圧接した状態に設定されている。円筒状スクリーン版の内周面とスキージとの間には、捺染糊が供給され、円筒状スクリーン版の外周面には布帛が圧接するようにバックアップローラが配設される。そして、円筒状スクリーン版を回転させることで、捺染糊がスキージにより堰き止められて円筒状スクリーン版から押し出されるようになり、円筒状スクリーン版と同期して回転するバックアップローラにより搬送される布帛の片面に捺染糊が印捺処理されていくようになる。 Examples of the rotary screen printing machine for printing a printing paste containing a polymer material include, for example, an apparatus using a cylindrical screen plate, but other known rotary screen printing machines may also be used, and particularly limited. Not. An apparatus using a cylindrical screen plate is set so that a squeegee is disposed inside a metal cylindrical screen plate and the tip of the squeegee is in pressure contact with the inner peripheral surface of the cylindrical screen plate. Printing paste is supplied between the inner peripheral surface of the cylindrical screen plate and the squeegee, and a backup roller is disposed on the outer peripheral surface of the cylindrical screen plate so that the fabric is in pressure contact. Then, by rotating the cylindrical screen plate, the printing paste is blocked by the squeegee and pushed out of the cylindrical screen plate, and the fabric conveyed by the backup roller that rotates in synchronization with the cylindrical screen plate. Printing paste is printed on one side.
ロータリスクリーン捺染機のスクリーンのメッシュ数は、１インチ当りのメッシュ数が２０メッシュ〜５００メッシュに設定するとよく、より好ましくは、３０メッシュ〜３００メッシュに設定するとよい。メッシュ数が２０より小さくなると、布帛表面に付与された捺染糊の分布が粗くなって高分子材料の均一に拡がらなくなり、防風効果が弱くなる。メッシュ数が５００を超えると、捺染糊が高粘度であるため、塗糊量が著しく減少し、十分な量の高分子材料を付与できなくなる。 The number of meshes of the screen of the rotary screen printing machine may be set to 20 to 500 mesh, more preferably 30 to 300 mesh per inch. When the number of meshes is less than 20, the distribution of the printing paste applied to the fabric surface becomes coarse and the polymer material does not spread uniformly, and the windproof effect is weakened. If the number of meshes exceeds 500, the printing paste has a high viscosity, so that the amount of coating paste is remarkably reduced and a sufficient amount of polymer material cannot be applied.
高分子材料を含む捺染糊の塗糊量は、布帛の片面に１０ｇ／ｍ2〜１００ｇ／ｍ2付与するとよく、より好ましくは、１５ｇ／ｍ2〜８０ｇ／ｍ2付与するとよい。塗糊量が１０ｇ／ｍ2より少なくなると、十分な防風効果を得ることができず、塗糊量が１００ｇ／ｍ2より多くなると、布帛が固くなって柔軟性が損なわれ、また捺染糊の内部まで乾燥するために乾燥時間が長くなる。 Coating glue amount of printing paste comprising a polymeric material may when 10g / m 2 ~100g / m 2 applied to one surface of the fabric, more preferably, may 15g / m 2 ~80g / m 2 to impart. When the coating amount is less than 10 g / m 2 , a sufficient windproof effect cannot be obtained, and when the coating amount is more than 100 g / m 2 , the fabric becomes hard and the flexibility is impaired, and the printing paste The drying time becomes longer because the inside is dried.
吸水性を有する布帛に捺染糊を付与する場合、捺染糊が布帛内部に吸収されてしまい、十分な防風効果が得られなくなる。そのため、捺染糊が布帛内部に吸収されるのを阻害する必要がある。捺染糊を付与する前に布帛表面に吸水阻害処理を行い、捺染糊が吸収されるのを阻害するようにする。 When a printing paste is applied to a fabric having water absorption, the printing paste is absorbed inside the fabric, and a sufficient windproof effect cannot be obtained. Therefore, it is necessary to inhibit the printing paste from being absorbed into the fabric. Before the printing paste is applied, the fabric surface is subjected to water absorption inhibition treatment to inhibit the printing paste from being absorbed.
撥水剤としては、布帛表面の吸水性を阻害する機能を有するものであればよく、例えば、フッ素系樹脂、シリコン系樹脂、パラフィン系樹脂、エチレン尿素系樹脂、脂肪酸系樹脂等が挙げられ、これらを複数混合した樹脂を用いてもよい。撥水剤の布帛への付与は、布帛の吸水性に応じて適宜設定すればよく、好ましくは、０．１％〜１０％の撥水剤をパディング処理により付与すればよい。 The water repellent is not particularly limited as long as it has a function of inhibiting the water absorption of the fabric surface, and examples thereof include fluorine resins, silicon resins, paraffin resins, ethylene urea resins, fatty acid resins, and the like. You may use resin which mixed these two or more. The application of the water repellent to the fabric may be appropriately set according to the water absorption of the fabric, and preferably 0.1% to 10% of the water repellent may be applied by padding.
ロータリスクリーン捺染機により捺染糊が印捺された布帛は、公知の乾燥機により乾燥されて高分子材料が布帛に付着した状態で固定される。乾燥温度は、捺染糊が十分乾燥する温度にすればよい。 The fabric on which the printing paste is printed by the rotary screen printing machine is dried by a known dryer and fixed in a state where the polymer material is adhered to the fabric. The drying temperature may be a temperature at which the printing paste is sufficiently dried.
高分子材料が付着固定した布帛の全面をカレンダー加工により圧縮加熱処理する。カレンダー加工は、公知のカレンダー加工機を用いて行えばよく、加熱されたカレンダーロールの間に布帛を挟持して加圧することで圧縮加熱処理する。この処理により、布帛に付着固定した高分子材料が溶融して布帛の表面全体に均一に拡がるようになり、布帛全体に均一に拡がった高分子材料により布帛表面全体に防風性を付与することができる。また、ロータリスクリーン捺染機により印捺した高分子材料をカレンダー加工により溶融させて薄く延ばすように拡げるので、高分子材料が薄く拡がって布帛自体の風合い（柔軟性）を損なうことがない。そして、カレンダー加工により布帛表面の凹凸が均されてチョークマークに対する改善効果も得ることができる。 The entire surface of the fabric to which the polymer material is adhered and fixed is subjected to compression and heat treatment by calendaring. The calendering process may be performed using a known calendering machine, and a compression heating process is performed by sandwiching and pressing a fabric between heated calender rolls. By this treatment, the polymer material adhered and fixed to the fabric is melted and spreads uniformly over the entire surface of the fabric, and the windproof property is imparted to the entire fabric surface by the polymer material uniformly spread over the entire fabric. it can. Further, since the polymer material printed by the rotary screen printing machine is melted by calendering and spreads so as to extend thinly, the polymer material spreads thinly and does not impair the texture (flexibility) of the fabric itself. And the unevenness | corrugation of the fabric surface is leveled by the calendar process, and the improvement effect with respect to a chalk mark can also be acquired.
カレンダー加工では、加熱温度を１２０℃〜２５０℃に設定して行うとよく、より好ましくは、１５０℃〜２００℃に設定して行うとよい。また、加熱温度以外の処理条件としては、ニップ圧を１ｋｇ／ｃｍ2〜１０ｋｇ／ｃｍ2、処理速度を６ｍ／分〜３０ｍ／分に設定すればよく、処理する布帛に応じて所望の風合い及び防風効果が得られるように各条件を選定すればよい。加熱温度が低くニップ圧が低い場合には、十分な防風効果を得ることができず、加熱温度が高くニップ圧が高い場合には、処理面に見栄えの悪い光沢（いわゆる、アタリ）が生じるようになって布帛の品質が劣化する。 In calendering, the heating temperature may be set to 120 ° C. to 250 ° C., more preferably 150 ° C. to 200 ° C. Further, as processing conditions other than the heating temperature, the nip pressure may be set to 1 kg / cm 2 to 10 kg / cm 2 , and the processing speed may be set to 6 m / min to 30 m / min. What is necessary is just to select each condition so that a windbreak effect may be acquired. When the heating temperature is low and the nip pressure is low, a sufficient windproof effect cannot be obtained, and when the heating temperature is high and the nip pressure is high, an unsightly gloss (so-called “atari”) appears on the treated surface. As a result, the quality of the fabric deteriorates.
なお、上述したように防風性を付与した布帛は、布帛自体が備えていた撥水性を低下させる場合がある。その場合には、捺染糊を印捺後でカレンダー加工前に撥水剤を布帛に付与してからカレンダー加工すればよい。撥水剤としては、上述した撥水剤と同様のものを用いればよく、また、布帛に撥水剤を付与する場合においても公知の方法により付与すればよく、特に限定されるものではないが、好ましくはパディング処理により付与すればよい。 In addition, as described above, the fabric imparted with windproof properties may reduce the water repellency of the fabric itself. In that case, it is only necessary to apply a water repellent to the fabric after the printing paste is printed and before the calendering, and then calendering. As the water repellent, the same water repellent as described above may be used, and even when the water repellent is applied to the fabric, it may be applied by a known method and is not particularly limited. Preferably, it may be applied by padding.
以上説明した布帛の加工方法を行うことで、布帛の後加工により風合いを損なうことなく防風性を付与することが可能となる。 By performing the fabric processing method described above, it is possible to impart windproof properties without damaging the texture by post-processing of the fabric.

Fabric H; Fabric I which performs only the printing paste application process and does not perform calendering; Air permeability (cm 3 / cm) for the fabrics F to I processed as described above, in which neither the application of printing paste nor calendering is performed 2 / second; JIS L1018 compliant) was measured. The measurement results were 12.9 for Fabric F, 9.5 for Fabric G, 17.5 for Fabric H, and 356.2 for Fabric I. The fabrics F and G that have been calendered have a reduced air permeability compared to the fabric H that has not been calendered, and the fabric G has a permeability that is halved compared to the fabric H and is significantly windproof. You can see that it has improved.
＜実施例３＞
布帛として、ナイロン繊維５０％及びポリエステル繊維５０％からなる丸編天竺の編物を用い、染色処理後仮セット工程を行い、上述した捺染糊の付与工程を行った。
<Example 3>
As the fabric, a knitted fabric of circular knitting made of 50% nylon fiber and 50% polyester fiber was used, and after the dyeing treatment, a temporary setting step was performed, and the above-described printing paste applying step was performed.
仮セット工程では、布帛Ｊについては水仕上げを行って１７０℃で１分間熱セットした。また、布帛Ｋについては、シリコン剤（北広ケミカル株式会社製）の１％水溶液をパディング処理により付与し、１７０℃で１分間熱セットした。 In the temporary setting step, the fabric J was water-finished and heat-set at 170 ° C. for 1 minute. For fabric K, a 1% aqueous solution of a silicon agent (made by Kitahiro Chemical Co., Ltd.) was applied by padding treatment and heat-set at 170 ° C. for 1 minute.
付与工程では、捺染糊として、水６０重量％、ウレタン樹脂（第一工業製薬株式会社製）４０重量％（高分子材料である固形分は２０重量％）を混合して調製した。捺染糊の粘度は、７，０００ｍＰａ・Ｓに設定した。実施例１と同様のロータリスクリーン捺染機（１インチ当りのメッシュ数９０）により布帛の片面に捺染糊の塗糊量３８ｇ／ｍ2で全面に印捺した。捺染糊の印捺後布帛を１９０℃で１分間加熱して捺染糊を乾燥させた。 In the application step, 60% by weight of water and 40% by weight of urethane resin (Daiichi Kogyo Seiyaku Co., Ltd.) (solid content of polymer material is 20% by weight) were mixed as printing paste. The viscosity of the printing paste was set to 7,000 mPa · S. Using the same rotary screen printing machine as in Example 1 (90 meshes per inch), the entire surface was printed on one side of the fabric with the amount of printing paste of 38 g / m 2 . After printing the printing paste, the fabric was heated at 190 ° C. for 1 minute to dry the printing paste.
比較のため、未加工の布帛Ｌを用意し、加工した布帛Ｊ及びＫとともに通気度（ｃｍ3／ｃｍ2／秒；ＪＩＳ Ｌ１０１８準拠）の測定を行った。測定結果は、布帛Ｊで１４６．８、布帛Ｋで６６．９、布帛Ｌで１９０．８であった。シリコン剤により撥水処理して吸水を阻害した布帛Ｋは、撥水処理されていない布帛Ｊに比べて通気度が半減しており、捺染糊の付与工程の前に撥水処理を行うことで防風性の大幅な改善を図れることがわかる。 For comparison, an unprocessed fabric L was prepared, and the air permeability (cm 3 / cm 2 / sec; conforming to JIS L1018) was measured together with the processed fabrics J and K. The measurement results were 146.8 for Fabric J, 66.9 for Fabric K, and 190.8 for Fabric L. Fabric K, which has been water-repellent treated with a silicone agent to inhibit water absorption, has half the air permeability compared to fabric J that has not been subjected to water-repellent treatment, and the water-repellent treatment is performed before the printing paste application step. It can be seen that the windbreakability can be greatly improved.
＜実施例４＞
布帛としてポリエステル繊維１００％のバックハーフを用い、染色処理後仮セット工程を行い、上述した捺染糊の付与工程を行った。
<Example 4>
A back half of 100% polyester fiber was used as the fabric, a temporary setting step was performed after the dyeing treatment, and the above-described printing paste applying step was performed.
仮セット工程では、フッ素系撥水剤（日華化学株式会社製）の５％水溶液をパディング処理により付与し、１７０℃で１分間熱セットした。 In the temporary setting step, a 5% aqueous solution of a fluorine-based water repellent (manufactured by Nikka Chemical Co., Ltd.) was applied by padding treatment and heat-set at 170 ° C. for 1 minute.
付与工程では、３つの布帛に対して以下の異なる組成の捺染糊を調製して付与した。
布帛Ｍ；水６０重量％、アクリル樹脂（日華化学株式会社製）４０重量％（高分子材料である固形分は２４重量％）
布帛Ｎ；水５０重量％、布帛Ｍと同様のアクリル樹脂４０重量％、浸透剤（日華化学株式会社製）１０重量％
布帛Ｏ；水４５重量％、布帛Ｍと同様のアクリル樹脂４０重量％、布帛Ｎと同様の浸透剤１５重量％
捺染糊の粘度は、いずれも５，０００ｍＰａ・Ｓに設定し、実施例１と同様のロータリスクリーン捺染機（１インチ当りのメッシュ数６０）により布帛の片面に捺染糊の塗糊量６８ｇ／ｍ2で全面に印捺した。捺染糊の印捺後布帛を１６５℃で１分間加熱して捺染糊を乾燥させた。
In the applying step, printing pastes having the following different compositions were prepared and applied to the three fabrics.
Fabric M: 60% by weight of water, 40% by weight of acrylic resin (manufactured by Nikka Chemical Co., Ltd.) (solid content of polymer material is 24% by weight)
Fabric N: 50% by weight of water, 40% by weight of acrylic resin similar to fabric M, 10% by weight of penetrant (manufactured by Nikka Chemical Co., Ltd.)
Fabric O: Water 45 wt%, acrylic resin 40 wt% similar to fabric M, penetrant 15 wt% similar to fabric N
The viscosity of the printing paste is set to 5,000 mPa · S, and the amount of the coating paste applied to one side of the fabric is 68 g / m using the same rotary screen printing machine (60 meshes per inch) as in Example 1. 2 printed on the entire surface. After printing the printing paste, the fabric was heated at 165 ° C. for 1 minute to dry the printing paste.
比較のため、未加工の布帛Ｐを用意し、加工した布帛Ｍ〜Ｏとともに通気度（ｃｍ3／ｃｍ2／秒；ＪＩＳ Ｌ１０１８準拠）の測定を行った。なお、布帛Ｍについては捺染糊を布帛表面に拡がるように付与できず、通気度の測定を行わなかった。測定結果は、布帛Ｎで１６．５、布帛Ｏで８．５、布帛Ｐで６２．４であった。浸透剤を添加した捺染糊を付与した布帛Ｎ及びＯは、未加工の布帛Ｊに比べて通気度が大幅に減少しており、また、浸透剤を添加していない布帛Ｍでは布帛表面の撥水性により捺染糊の付与ができないことからみて、捺染糊に浸透剤を添加することで捺染糊を布帛表面に付与して防風性の大幅な改善を図れることがわかる。 For comparison, an unprocessed fabric P was prepared, and the air permeability (cm 3 / cm 2 / sec; conforming to JIS L1018) was measured together with the processed fabrics M to O. For fabric M, the printing paste could not be applied to spread on the fabric surface, and the air permeability was not measured. The measurement results were 16.5 for fabric N, 8.5 for fabric O, and 62.4 for fabric P. The fabrics N and O to which the printing paste with the penetrant added is applied have a significantly reduced air permeability as compared with the unprocessed fabric J, and the fabric M without the penetrant has a repellent surface. In view of the fact that the printing paste cannot be applied due to water, it can be seen that by adding a penetrating agent to the printing paste, the printing paste can be applied to the fabric surface to significantly improve the windproof property.
