【発明の属する技術分野】
本発明は、ジアセテート繊維とカチオン可染性ポリエステル繊維から構成の織編物の抜蝕加工品及びその製造方法に関する。
【0002】
【従来の技術】
従来より、抜蝕性を異にする2種に繊維からなる織編物を抜蝕糊で柄状に印捺し抜蝕性の大なる繊維を脆化除去する抜蝕加工はオパール加工ともいわれ、広く知られており、アセテート繊維とポリエステル繊維からなる織編物を抜蝕糊で柄状に印捺してアセテート繊維を除去する抜蝕加工も、特公昭50−15915号公報、特公昭51−49040号公報、特公昭54−36280号公報等で知られている。
【0003】
しかしながら、アセテート繊維とポリエステル繊維からなる織編物の抜蝕加工において、ポリエステル繊維として、アセテート繊維とは異色染めが可能なカチオン染料で染色可能なカチオン可染性ポリエステル繊維を用いる場合は、抜蝕剤にもよるが、抜蝕部に残るカチオン可染性ポリエステル繊維の組織地の破裂強度の低下が生じ、またこの破裂強度の低下が経時的に増大するという問題がある。
【0004】
この抜蝕部のカチオン可染性ポリエステル繊維の組織地の破裂強度の低下は、抜蝕加工時に抜蝕剤に由来する酸が残存しカチオン可染性ポリエステル繊維が加水分解されることによって引き起こされると推定され、抜蝕加工時の印捺、熱処理後に、水洗を強化する手段を採っても残存する酸の完全除去には至らず根本的な問題解決とはなっていない。
【0005】
【発明が解決しようとする課題】
本発明は、アセテート繊維とカチオン可染性ポリエステル繊維からなる織編物の抜蝕加工において、アセテート繊維としてジアセテート繊維を用い、カチオン可染性ポリエステル繊維への影響の少ない抜蝕剤を選定すると共に、カチオン可染性ポリエステル繊維の組織地の破裂強度の低下を防止する後処理工程の採用について検討の結果、なされたものである。本発明の目的は、ジアセテート繊維とカチオン可染性ポリエステル繊維から構成の織編物よりジアセテート繊維が柄状に抜蝕され、抜蝕部でのカチオン可染性ポリエステル繊維の組織地の破裂強度の低下が少ない抜蝕加工品を提供し、またかかる抜蝕加工品を容易に得ることにある。
【0006】
【課題を解決するための手段】
本発明者は、ジアセテート繊維と、共重合成分として5−ナトリウムスルホイソフタル酸或いは更にアジピン酸が共重合されたポリエチレンテレフタレートからなるカチオン可染性ポリエステル繊維から構成された織編物より柄状にジアセテート繊維が抜蝕された抜蝕加工品であって、該加工品を温度70℃、湿度90%の雰囲気下で1週間保持したときの抜蝕部の非抜蝕部とのカチオン可染性ポリエステル繊維の組織地の破裂強度比が35%以上であることを特徴とする抜蝕加工品、
【0007】
及び、ジアセテート繊維と、共重合成分として5−ナトリウムスルホイソフタル酸或いは更にアジピン酸が共重合されたポリエチレンテレフタレートからなるカチオン可染性ポリエステル繊維から構成された織編物を、抜蝕剤として硫酸塩を含む抜蝕糊を柄状に印捺して熱処理し、水洗して印捺部のジアセテート繊維を除去した後、アンモニアを含む水溶液中で加温処理することを特徴とする抜蝕加工品の製造方法、にある。
【0008】
【発明の実施の形態】
本発明の抜蝕加工品における織編物は、ジアセテート繊維とカチオン可染性ポリエステル繊維とからなる織物、編物である。ジアセテート繊維は、酢化度が53.5〜57.5%のセルロースジアセテートからなるアセテート繊維であり、また、カチオン可染性ポリエステル繊維は、カチオン染料により染色可能な改質ポリエステル繊維で、共重合成分として5−ナトリウムスルホイソフタル酸が共重合されたポリエチレンテレフタレート、好ましくは5−ナトリウムスルホイソフタル酸及びアジピン酸が共重合されたポリエチレンテレフタレートからなるカチオン可染性ポリエステル繊維である。
【0009】
本発明の抜蝕加工品は、かかる織編物より柄状にジアセテート繊維が抜蝕された抜蝕加工品である。そして、本発明の抜蝕加工品は、この抜蝕加工品を70℃、90%RHの雰囲気下で1週間保持したときに、即ち約1年間の経日に相当する加速テストをしたときに、下記式でも表すように、抜蝕部の非抜蝕部とのカチオン可染性ポリエステル繊維の組織地の破裂強度比が35%以上であることを特徴とするものである。破裂強度比が35%未満では、抜蝕部のカチオン可染性ポリエステル繊維の組織地での破裂が生じ易く、抜蝕加工品として実用上不満足なものである。
【0010】
破裂強度比(%)=[抜蝕部のカチオン可染性ポリエステル繊維組織地の破裂強度/非抜蝕部のカチオン可染性ポリエステル繊維組織地の破裂強度]×100
式中、破裂強度単位:kg/cm2
【0011】
本発明の抜蝕加工品は、ジアセテート繊維とカチオン可染性ポリエステル繊維から構成の織編物より柄状にジアセテート繊維が抜蝕され、柄部の抜蝕部にはカチオン可染性ポリエステル繊維の組織地のみが存在することから、ジアセテート繊維は分散染料で、カチオン可染性ポリエステル繊維はカチオン染料で、それぞれ異色に着色されていることが織編物の特定の繊維構成上からも好ましいことである。
【0012】
次に、本発明の抜蝕加工品の製造方法について説明する。
本発明の抜蝕加工品は、ジアセテート繊維とカチオン可染性ポリエステル繊維から構成された織編物を、抜蝕剤として硫酸塩を含む抜蝕糊を柄状に印捺して熱処理し、水洗して印捺部のジアセテート繊維を除去した後、アンモニアを含む水溶液中で加温処理することにより製造される。
【0013】
抜蝕糊は、抜蝕剤と糊剤を含んで構成され、抜蝕剤としては、硫酸アルミニウム、硫酸第一鉄、硫酸第二鉄、硫酸銅、硫酸亜鉛、硫酸第一錫、硫酸水素ナトリウム等の硫酸塩、好ましくは硫酸アルミニウム、硫酸第一鉄、特にカチオン可染性ポリエステル繊維への損傷がない点で、硫酸アルミニウムが好ましく用いられる。また、糊剤としては、ローカストビーンガム系、デンプン系、デキストリン系、クリスタルガム系、トラガントガム系、セルロース系等の任意の糊剤の単独或いは2種以上の混合物が用いられる。
【0014】
抜蝕糊には、抜蝕剤では分解されないカチオン染料及び又は分散染料が含まれていてもよく、抜蝕糊にカチオン染料又は分散染料を含むときは、抜蝕と同時にカチオン可染性ポリエステル繊維を染色することが可能であり、いわゆるカチオン染料による発色性を活かした異色染めを行うこともできる。
【0015】
織編物としては、無色地の織編物、又は分散染料及び又はカチオン染料で地染め織編物を用いる。抜蝕糊の印捺には、捺染法、スプレイ法等が用いられ、捺染法としては型枠捺染法、フラットスクリーン法、ロータリースクリーン法、ローラー法等が用いられる。織編物に抜蝕糊を柄状に印捺した後は、適宜乾燥した後、熱処理する。
【0016】
熱処理は、飽和蒸気の場合は100〜140℃、乾熱の場合は100〜220℃、過熱蒸気の場合は130〜220℃で、30秒〜30分行うが、ジアセテート繊維及びカチオン可染性ポリエステル繊維を変色若しくは損傷させない温度及び時間を採用する必要がある。熱処理後は、水洗して印捺部の脆化したジアセテート繊維を除去する。
【0017】
本発明の抜蝕加工品の製造方法においては、水洗後、更に、アンモニアを含む水溶液中で加温処理することが必要であり、かかる処理により抜蝕剤に由来し抜蝕部のカチオン可染性ポリエステル繊維に残存する酸を中和して除去する上で極めて有効である。
【0018】
アンモニアを含む水溶液中での加温処理には、アンモニア水(28%濃度)を1〜20g/リットル含む水溶液が用いられ、50〜98℃で1〜30分浸漬処理する。このアンモニアを含む水溶液中での加温処理に際しては、アンモニアに加えて第4級アンモニウム塩を含む水溶液を用いることは、第4級アンモニウム塩により抜蝕部のカチオン可染性ポリエステル繊維内部への浸透を容易にし残存する酸の中和を促進させることから特に好ましいことである。
【0019】
用いられる第4級アンモニウム塩は、各種含窒素化合物の4級化したもので、アミン誘導体からのカチオン系界面活性剤として知られ、繊維分野では殺菌剤、帯電防止剤、柔軟仕上剤、アルカリ減量促進剤等として用いられるものであり、例えば、マーセリンPEF、マーセリンPES、マーセリンPEL(明成化学工業(株)製)、DYK−1125、DXK−10N(一方社油脂工業(株)製)、カチオゾールNS−11コンク(高松油脂(株)製)、ネオレートNCB(日華化学(株)製)、シルファインPE(センカ(株)製)等が用いられる。
【0020】
アンモニアを含む水溶液中での加温処理後は、水洗して本発明の抜蝕加工品を得る。抜蝕加工品には、織編物が無色地であるとき或いは抜蝕時に着色させないときは、必要に応じ後染めでカチオン染料及び又は分散染料で適宜染色を施す。
【0021】
得られた抜蝕加工品は、抜蝕加工によるカチオン可染性ポリエステル繊維の損傷、脆化が少なく、抜蝕部に残るカチオン可染性ポリエステル繊維の組織地が非抜蝕部でのカチオン可染性ポリエステル繊維の組織地に対して35%以上の高い破裂強度比を有する。
【0022】
【実施例】
以下、本発明を実施例により具体的に説明する。なお、実施例中、抜蝕加工品の抜蝕部の非抜蝕部とのカチオン可染性ポリエステル繊維の組織地の破裂強度比の測定は、抜蝕部と非抜蝕部を含む抜蝕加工布をアセトンに浸漬し、非抜蝕部のジアセテート繊維を溶解除去して行い、抜蝕加工上がりの抜蝕加工布及び温度70℃、湿度90%の雰囲気下で1週間保持後の抜蝕加工布について、抜蝕部及び非抜蝕部の各カチオン可染性ポリエステル繊維の組織地の破裂強度を測定し、破裂強度比を求めた。破裂強度の測定自体は、JIS L−1096 A法に拠った。

TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to a woven and knitted article formed from diacetate fibers and cationic dyeable polyester fibers, and a method for producing the same.
[0002]
[Prior art]
Conventionally, opaque processing is known as opal processing, in which a woven or knitted fabric made of two types of fibers with different erosion properties is printed in a pattern with erosion paste and embrittlement removal of fibers with high erosion properties. Also known is a method of printing a woven or knitted fabric composed of an acetate fiber and a polyester fiber in a pattern with a discharge paste to remove the acetate fiber, and Japanese Patent Publication No. 50-15915 and Japanese Patent Publication No. 51-49040. And Japanese Patent Publication No. 54-36280.
[0003]
However, in the case of using a cation-dyeable polyester fiber which can be dyed with a cationic dye capable of being dyed in a different color from the acetate fiber, in the case of using a woven or knitted fabric composed of an acetate fiber and a polyester fiber as the polyester fiber, However, there is a problem that the rupture strength of the woven fabric of the cationic dyeable polyester fiber remaining in the exfoliated portion is reduced, and that the rupture strength is increased with time.
[0004]
The decrease in the rupture strength of the cation-dyeable polyester fiber tissue at the exfoliated portion is caused by the acid derived from the exfoliant remaining during the exfoliation processing and the cation-dyeable polyester fiber being hydrolyzed. It is presumed that even if a means for strengthening water washing is adopted after printing and heat treatment at the time of the etching process, the remaining acid is not completely removed, and the fundamental problem has not been solved.
[0005]
[Problems to be solved by the invention]
The present invention uses a diacetate fiber as an acetate fiber in a woven or knitted fabric composed of an acetate fiber and a cationic dyeable polyester fiber, and selects a disinfectant having little effect on the cationic dyeable polyester fiber. This is the result of a study on the adoption of a post-treatment step for preventing a reduction in the bursting strength of the fabric of the cationic dyeable polyester fiber. SUMMARY OF THE INVENTION It is an object of the present invention to provide a diacetate fiber that is pitted in a pattern from a woven or knitted fabric composed of diacetate fiber and cationically dyeable polyester fiber, and that the rupture strength of the textured portion of the cationically dyeable polyester fiber at the portion to be removed. It is another object of the present invention to provide a processed product having a small reduction in the surface roughness and to easily obtain the processed product.

Manufacturing method.
[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
The woven or knitted fabric in the processed article of the present invention is a woven or knitted fabric composed of diacetate fibers and cationic dyeable polyester fibers. The diacetate fiber is an acetate fiber composed of cellulose diacetate having a degree of acetylation of 53.5 to 57.5%, and the cationic dyeable polyester fiber is a modified polyester fiber dyeable with a cationic dye. copolymerizing 5-sodium sulfoisophthalic acid as a component copolymerized polyethylene terephthalate, preferably cationic dyeable polyester fiber made of polyethylene terephthalate sodium sulfoisophthalic acid and adipic acid 5 is copolymerized.
[0009]
The exfoliated processed product of the present invention is an exfoliated processed product in which diacetate fibers are exfoliated in a pattern from such a woven or knitted fabric. Then, the processed product of the present invention is obtained when the processed product is held for one week in an atmosphere of 70 ° C. and 90% RH, that is, when an accelerated test corresponding to a day of about one year is performed. As represented by the following formula, the rupture strength ratio of the textured portion of the cationically dyeable polyester fiber to the non-discharged portion of the discolored portion is 35% or more. If the burst strength ratio is less than 35%, the cation-dyeable polyester fiber in the exfoliated portion tends to rupture at the textured area, which is practically unsatisfactory as an exfoliated product.
[0010]
Burst strength ratio (%) = [rupture strength of cationically dyeable polyester fiber tissue at the part to be removed / rupture strength of cationic dyeable polyester fiber tissue at the part to be removed] × 100
In the formula, burst strength unit: kg / cm 2
[0011]
In the processed product of the present invention, a diacetate fiber is eroded in a pattern from a woven or knitted fabric composed of diacetate fiber and cationically dyeable polyester fiber, and a cation-dyeable polyester fiber is formed in the evacuated portion of the handle. Diacetate fibers are disperse dyes, and cation-dyeable polyester fibers are cationic dyes, and it is preferable from the viewpoint of the specific fiber structure of the woven or knitted fabric that only the diacetate fibers are disperse dyes and the cationic dyeable polyester fibers are cationic dyes. It is.
[0012]
Next, a method for producing a processed product of the present invention will be described.
The processed product of the present invention is a woven or knitted fabric composed of diacetate fiber and cationic dyeable polyester fiber, which is subjected to heat treatment by printing a discharge paste containing a sulfate as a discharge agent in a pattern, followed by washing with water. After removing the diacetate fiber from the printing portion by heating, the fabric is manufactured by heating in an aqueous solution containing ammonia.
[0013]
The disinfecting paste is composed of a disinfectant and a paste, and the disinfectant includes aluminum sulfate, ferrous sulfate, ferric sulfate, copper sulfate, zinc sulfate, stannous sulfate, sodium hydrogen sulfate Sulfates, such as aluminum sulfate, ferrous sulfate, especially aluminum sulfate are preferably used in that they do not damage the cationically dyeable polyester fiber. As the sizing agent, any sizing agent such as a locust bean gum type, a starch type, a dextrin type, a crystal gum type, a tragacanth type, a cellulose type, or a mixture of two or more types is used.
[0014]
The discharge paste may contain a cationic dye and / or a disperse dye which is not decomposed by the discharge agent. When the discharge paste contains a cationic dye or a disperse dye, the cationic dyeable polyester fiber is simultaneously discharged and discharged. Can be dyed, and it is also possible to carry out a different-color dyeing utilizing a color developing property by a so-called cationic dye.
[0015]
As the woven or knitted fabric, a colorless woven or knitted fabric or a woven or knitted fabric dyed with a disperse dye and / or a cationic dye is used. A printing method, a spray method, or the like is used for printing of the discharge paste, and a form printing method, a flat screen method, a rotary screen method, a roller method, or the like is used as the printing method. After the woven or knitted fabric is printed with the disinfecting paste in a pattern, it is appropriately dried and then heat-treated.
[0016]
The heat treatment is performed at 100 to 140 ° C. for saturated steam, 100 to 220 ° C. for dry heat, and 130 to 220 ° C. for superheated steam for 30 seconds to 30 minutes. It is necessary to employ a temperature and time that do not discolor or damage the polyester fibers. After the heat treatment, it is washed with water to remove the embrittled diacetate fibers in the printed portion.
[0017]
In the method for producing a processed product according to the present invention, after washing with water, it is necessary to further carry out a heating treatment in an aqueous solution containing ammonia. It is extremely effective in neutralizing and removing the acid remaining in the conductive polyester fiber.
[0018]
For the heating treatment in an aqueous solution containing ammonia, an aqueous solution containing 1 to 20 g / liter of aqueous ammonia (28% concentration) is used, and immersion treatment is performed at 50 to 98 ° C. for 1 to 30 minutes. In the heating treatment in an aqueous solution containing ammonia, the use of an aqueous solution containing a quaternary ammonium salt in addition to the ammonia can prevent the cation-dyeable polyester fiber from being removed by the quaternary ammonium salt. This is particularly preferred because it facilitates penetration and promotes neutralization of residual acids.
[0019]
The quaternary ammonium salt used is a quaternized form of various nitrogen-containing compounds, and is known as a cationic surfactant derived from an amine derivative. In the field of textiles, a bactericide, an antistatic agent, a softening agent, an alkali reducing agent is used. For example, mercerin PEF, mercerin PES, mercerin PEL (manufactured by Meisei Chemical Co., Ltd.), DYK-1125, DXK-10N (manufactured by Yushi Yushi Kogyo Co., Ltd.), and cationthio NS -11 conc (manufactured by Takamatsu Oil & Fats Co., Ltd.), Neolate NCB (manufactured by Nichika Chemical Co., Ltd.), Sylfine PE (manufactured by Senka Co., Ltd.) and the like are used.
[0020]
After the heating treatment in an aqueous solution containing ammonia, the product is washed with water to obtain a processed product of the present invention. When the woven or knitted material is a colorless ground or is not colored at the time of the erosion, the erosion-processed product is appropriately dyed with a cationic dye and / or a disperse dye as needed after dyeing.
[0021]
The resulting exfoliated processed product has less damage and embrittlement of the cationic dyeable polyester fiber due to the exfoliation process, and the texture of the cationic dyeable polyester fiber remaining in the exfoliated area is cationically exfoliated in the non-exfoliated area. It has a high burst strength ratio of 35% or more based on the texture of the dyeable polyester fiber.
[0022]
【Example】

In the examples, the measurement of the rupture strength ratio of the cation-dyeable polyester fiber tissue ground with the non-exposed portion of the extruded portion of the extruded processed product was performed using the extruded portion including the extruded portion and the non-extracted portion. The work cloth is immersed in acetone to dissolve and remove the diacetate fiber in the non-extracted area. The exfoliated cloth after the exfoliation processing and the extraction after holding for 1 week in an atmosphere of 70 ° C. and 90% humidity. With respect to the erosion-treated cloth, the burst strength of the textured area of each cationically dyeable polyester fiber in the extracted and non-extracted portions was measured, and the burst strength ratio was determined. The measurement of the burst strength itself was based on JIS L-1096A method.

(Example 4)
Cationic dyeable polyester fiber consisting of polyethylene terephthalate of 75 denier / 21 denier of diacetate fiber at the front and 2.25 mol% of 5-sodium sulfoisophthalic acid and 5.0 mol% of adipic acid at the middle and back of the fiber. Using a 37-filt / inch, 53-course / inch tricot brushed knitted fabric (front 10/67, middle 10/12, back 23/10) with 36 filaments, the following disinfecting paste is applied to this knit by a flat screen method. The pattern was printed.
[0033]
[0034]
After printing, it was pre-dried at 100 ° C., heat-treated at 135 ° C. for 4 minutes, and washed with water. Next, it was immersed in the following aqueous solution containing ammonia at 90 ° C. for 20 minutes, subjected to ammonia treatment, washed with water, and dried. The obtained exfoliated processed product has a well-patterned patterned pattern, and the obtained exfoliated processed product has a rupture strength of the cation-dyeable polyester fiber tissue in the exfoliated area, The rupture strength ratio of the woven fabric of the cationic dyeable polyester fiber to the non-discharged portion of the portion was determined and is shown in Table 4.

【The invention's effect】
In the processed product of the present invention, the diacetate fiber is satisfactorily eroded in a pattern from a woven or knitted fabric composed of diacetate fiber and cation-dyeable polyester fiber. The rate of reduction of the burst strength of the cationically dyeable polyester fiber in the non-extracted area of the tissue area relative to the tissue area is small, and it is an exfoliated processed product that is less likely to burst in the exfoliated area. It is a processed product that is colored in different colors by the dye applied to the fiber and the cationic dyeable polyester fiber, respectively, and thus is suitable for the field of clothing.
