Description
본 발명은 인체친화적, 친환경소재인 모달섬유사 및 PLA사를 사용하여 제직한 모달―PLA 교직물의 경량성, 부드러운 촉감 및 형태안정성을 향상시키기 위한 친환경 효소가공방법에 관한 것이다. 특히, 본 발명은 대구광역시에 지원하는 " 2022년 친환경 생분해 섬유소재산업 활성화 지원사업" 수행의 일환으로 개발된 것이다. The present invention relates to an eco-friendly enzyme processing method to improve the lightness, soft feel and dimensional stability of modal-PLA cross fabric woven using modal fiber yarn and PLA yarn, which are human-friendly and eco-friendly materials. In particular, this invention was developed as part of the "2022 Eco-friendly biodegradable fiber material industry revitalization support project" supported by Daegu Metropolitan City.
환경과 건강에 대한 관심이 증대되면서 섬유산업에서 고부가가치 시장을 형성하는 섬유소재 분야에 대한 관심이 증대되고 있다. 특히, 천연 섬유의 촉감과 특성을 나타내는 소재 역시 고급화 및 고기능화되고 있는 추세로서 친환경, 인체친화형천연소재분야에 대한 연구가 활발히 전개되면서 초경량성, 쾌적성, 친환경적, 인체친화적인 소재로 만든 섬유제품에 대한 기술적인 요구가 증가하고 있는 실정이다As interest in the environment and health increases, interest in the field of textile materials, which forms a high value-added market in the textile industry, is increasing. In particular, materials that display the feel and characteristics of natural fibers are also becoming more advanced and highly functional. As research into the field of eco-friendly, human-friendly natural materials is actively conducted, textile products made from ultra-light, comfortable, eco-friendly, and human-friendly materials are emerging. The technical demand for
그 중 모달은 너도밤나무 펄프를 연료로 하여 셀룰로오스 연신, 습식방사법을 통해 생산되어 강도와 형태안정성이 우수한 장점을 가지는 레이온섬유의 한 종류로서 면섬유보다 수축이 적고 탄성회복율이 좋아서 질감이 더 부드럽고 윤기가 나는 섬유재료로서 최근 각광을 받고 있다. Among them, modal is a type of rayon fiber that is produced through cellulose stretching and wet spinning using beech tree pulp as fuel and has the advantage of excellent strength and shape stability. It shrinks less than cotton fiber and has a good elastic recovery rate, making the texture softer and glossier. I have recently been in the spotlight as a textile material.
이러한 모달섬유는 천연셀룰로오스보다 결정성이 낮아 흡습성이 크므로 이너웨어용 속옷재질로 사용되며, 모달, 폴리에스터 교직물을 통해 여성 블라우스 및 남성 셔츠 용도로의 사용이 증가되고 있는 추세이다. These modal fibers have lower crystallinity than natural cellulose and are highly hygroscopic, so they are used as underwear materials for innerwear, and the use of modal and polyester cross-woven fabrics for women's blouses and men's shirts is increasing.
한편, PLA (Poly Lactic Acid)섬유는 옥수수등을 발효한 글루코스로부터 얻은 젖산을 탈수하여 축합반응을 거쳐 얻은 섬유로써 폴리에스테르나 나일론과 같은 합성섬유와 같이 용융방사 및 상품화 공정을 통하여 제조되는 섬유로서 미생물에 의해 섬유 내에 도입된 사슬이 절단되어 무기물화될 수 있어 생분해성 섬유로서 폐기되어도 환경문제를 초래하지 않는 장점을 가진다.Meanwhile, PLA (Poly Lactic Acid) fiber is a fiber obtained through a condensation reaction by dehydrating lactic acid obtained from glucose obtained from fermenting corn, etc. It is a fiber manufactured through melt spinning and commercialization processes like synthetic fibers such as polyester or nylon. The chains introduced into the fiber by microorganisms can be cut and mineralized, so it has the advantage of not causing environmental problems even when discarded as a biodegradable fiber.
이러한 친환경, 인체친화적인 섬유소재인 모달섬유와 PLA섬유를 사용하여 경량감과 드레이프성이 우수한 소프트한 촉감을 가지는 침구용원단이나 의류용원단으로 활용할 수 있겠으나, 모우가 많은 모달섬유의 표면특성상 교직물의 경량성, 부드러운 촉감 및 드레이프성이 저하되며, 고온과 습도에 취약한 PLA(Poly Lactic Acid)섬유의 특성상 후가공의 조건이 제약이 많아 모달-PLA 교직물의 후기공에 어려움을 겪는 실정이다.Modal fiber and PLA fiber, which are eco-friendly and human-friendly fiber materials, can be used as bedding fabric or clothing fabric with a soft touch that is lightweight and has excellent drape properties. However, due to the surface characteristics of modal fiber, which has a lot of wool, it can be used as a knitted fabric. The lightness, soft feel, and drapability of the fabric are reduced, and due to the nature of PLA (Poly Lactic Acid) fibers, which are vulnerable to high temperature and humidity, post-processing conditions are limited, making post-processing of modal-PLA cross fabric difficult.
그러므로 본 발명에서는 모우가 많은 모달섬유의 표면특성을 개선하여 교직물의 경량성, 부드러운 촉감 및 드레이프성을 향상시키고 직물수축성의 형태안정성을 부여하는 한편, 고온과 습도에 취약한 PLA(Poly Lactic Acid)섬유사의 강도저하(Strength loss)가 거의 없도록 하여 직물손상이 발생하지 않고, 옷감무게 감소(Weight loss)가 적어 품질 향상 및 형태안정유지가 우수하고, 직물의 염료가 빠져 나오는 것을 최소화하는 친환경 효소가공방법을 제공하는 것을 기술적과제로 한다.Therefore, in the present invention, by improving the surface properties of modal fibers with a lot of hair, the lightweight, soft touch and drape properties of the cross fabric are improved, and the dimensional stability of the fabric shrinkage is provided, while PLA (Poly Lactic Acid) fibers, which are vulnerable to high temperature and humidity, are improved. An eco-friendly enzyme processing method that minimizes the loss of dye from the fabric, prevents damage to the fabric by minimizing the loss of yarn strength, improves quality and maintains shape stability by reducing the weight loss of the fabric, and minimizes the loss of dye from the fabric. The technical task is to provide .
그러므로 본 발명에 의하면, 모달섬유사 및 PLA사를 사용하여 제직한 교직물의 호발·정련공정;Therefore, according to the present invention, the sizing and refining process of the cross fabric woven using modal fiber yarn and PLA yarn;
상기 직물의 모달섬유사의 표면 잔털을 제거하는 모소공정;A hair removal process to remove surface fine hairs of the modal fiber yarns of the fabric;
이후 상기 직물을 셀룰라아제 3~8% O.W.F를 함유하는 효소가공액에 처리하는 효소감량가공 및 수세공정으로 이루어지는 것을 특징으로 하는 모달―PLA 교직물의 친환경 효소가공방법이 제공된다. An eco-friendly enzyme processing method for Modal-PLA cross fabric is provided, which is characterized in that the fabric is treated with an enzyme processing solution containing 3-8% O.W.F. of cellulase followed by enzyme reduction processing and a water washing process.
이하 본 발명을 보다 상세히 설명하기로 한다. Hereinafter, the present invention will be described in more detail.
본 발명은 친인체, 친환경소재인 모달섬유사 및 PLA사를 사용하여 제직한 모달―PLA 교직물의 경량성, 부드러운 촉감 및 드레이프성을 향상시키기 위한 친환경 효소가공방법에 관한 것으로서 크게 호발·정련공정, 모소공정, 효소감량가공 및 수세공정으로 이루어진다.The present invention relates to an eco-friendly enzyme processing method to improve the lightness, soft touch and drapability of modal-PLA cross fabric woven using modal fiber yarn and PLA yarn, which are human-friendly and eco-friendly materials. It mainly involves a desizing and refining process; It consists of moso process, enzyme reduction processing, and water washing process.
본 발명의 가공대상이 되는 모달―PLA 교직물은 모달섬유사 및 PLA사를 사용하여 제직한 교직물로서 모달섬유사를 경사로, PLA사를 위사로 사용할 수도 있고, 반대로 모달섬유사를 위사로, PLA사를 경사로 사용할 수도 있다.The modal-PLA interwoven fabric, which is the processing target of the present invention, is a interwoven fabric woven using modal fiber yarns and PLA yarns. Modal fiber yarns can be used as warp yarns and PLA yarns can be used as weft yarns. Conversely, modal fiber yarns can be used as weft yarns and PLA yarns can be used as yarns. can also be used as a slope.
상기 모달섬유사는 레이온의 한 종류로서 면섬유보다 수축이 적고 탄성회복율이 좋아서 질감이 더 부드럽고 윤기가 나는 섬유재료이다. 이는 천연셀룰로오스보다 결정성이 낮아 흡습성이 크므로 이너웨어용 속옷재질로 사용되며, 폴리에스터와의 교직물을 통해 여성 블라우스 및 남성 셔츠 용도로도 사용된다.The modal fiber yarn is a type of rayon and is a textile material that has less shrinkage and better elastic recovery than cotton fiber, making the texture softer and more shiny. It has lower crystallinity and greater hygroscopicity than natural cellulose, so it is used as an underwear material for innerwear, and is also used for women's blouses and men's shirts through a cross-woven fabric with polyester.
상기 PLA(Poly Lactic Acid)섬유사는 옥수수전분 사용소재를 이용한 친환경섬유소재로 인장강도는 폴리에스터와 유사한 수준이나 고온과 습도에 취약하며, 내마모성이 취약한 특성을 가지고 있다.The PLA (Poly Lactic Acid) fiber yarn is an eco-friendly fiber material made from corn starch. Its tensile strength is similar to that of polyester, but it is vulnerable to high temperature and humidity, and has poor abrasion resistance.
먼저, 상기 모달―PLA 교직물을 효소가공하기 전에 호발·정련공정을 하게 되는데, 일반적인 면직물의 전처리(호발, 정련, 수세) 공정과 유사하게 진행하되, 호발시 호발효소인 아밀라아제를 사용하여 직물내에 존재하는 호부 제거가 중요하다. 이때 직물 조직을 충분히 이완시킴으로써 후에 행할 효소감량가공에서 호부줄이 생기는 것을 방지할 수 있다. 상기 호발효소의 성능 향상을 위해 비이온성 습윤제 또는 분산제를 첨가하여 사용하면 더욱 바람직하다. PLA(Poly Lactic Acid)섬유사는 고온과 습도에 취약하므로 정련시 90~120℃ 이내의 온도설정으로 정련공정을 거쳐야 한다. First, before enzymatically processing the modal-PLA fabric, a desizing and scouring process is performed. It is similar to the pretreatment (sizing, scouring, washing) process of general cotton fabrics, but during desizing, amylase, a desizing enzyme, is used to remove the desizing and scouring process from the fabric. It is important to remove the markings. At this time, by sufficiently relaxing the fabric tissue, it is possible to prevent wrinkles from forming during the enzyme weight loss processing to be performed later. To improve the performance of the desizing enzyme, it is more preferable to add a nonionic wetting agent or dispersing agent. PLA (Poly Lactic Acid) fiber yarn is vulnerable to high temperature and humidity, so it must go through a refining process at a temperature setting of 90 to 120 degrees Celsius.
호발·정련공정완료 후에는 모소공정을 하게 되는데, 본 발명의 목적인 모달―PLA 교직물의 경량성, 부드러운 촉감 및 드레이프성을 향상시키기 위해 교직물의 모달섬유사에 존재하는 표면 잔털을 제거하는 모소공정을 하게 된다. After the sizing and refining process is completed, a brining process is performed. In order to improve the lightness, soft touch, and drapability of the modal-PLA cross fabric, which is the object of the present invention, a brining process is performed to remove surface fine hairs present in the modal fiber yarns of the woven fabric. I do it.
상기 모소공정은 통상적인 면직물의 모소공정과 동일한 방법으로 행하되, 불꽃길이를 1.5~2.5㎜로 조절하여 직물에 존재하는 모달섬유사의 표면의 잔털을 태우는 것이 바람직한데, 불꽃길이 1.5㎜ 미만에서는 모달섬유사의 표면의 잔털을 태우기가 어려우며, 불꽃길이 2.5㎜보다 큰 경우에는 교직물내에 함께 존재한 PLA섬유사가 열변화를 일으킬 우려가 있다.The hair braiding process is performed in the same manner as the conventional cotton fabric wool braiding process, but it is preferable to adjust the flame length to 1.5 to 2.5 mm to burn the fine hairs on the surface of the modal fiber yarns present in the fabric. If the flame length is less than 1.5 mm, the modal fiber It is difficult to burn the fine hair on the surface of the yarn, and if the flame length is greater than 2.5 mm, there is a risk that the PLA fiber yarn present in the cross fabric may cause thermal change.
모소공정이후 상기 직물을 셀룰라아제 3~8% O.W.F를 함유하는 효소가공액에 처리하는 효소감량가공하게 된다. 상기 효소감량가공의 효소인 셀룰라아제는 모달섬유사 표면의 모우를 제거하여 교직물의 경량성, 부드러운 촉감을 향상시키고 직물수축성의 형태안정성을 부여하는 것으로서 PLA섬유사의 강도저하(Strength loss)가 거의 없어 직물손상이 발생하지 않고, 옷감무게 감소(Weight loss)가 적어 품질 향상 및 형태안정유지가 우수하고, 직물의 염료가 빠져 나오는것(Color pull, Shade change)을 최소화할 수 있는 것이 장점이다. 또한, 용수의 pH조정이 별로 필요치 않아 공정시간 절약효과가 있으며, 40℃정도의 저온탕에서 작업가능하므로 에너지 절약효과가 높다. 가공시간은 15 ~ 60분이며, 사용량은 3~8% O.W.F 사용하는 것이 좋은데. 3% O.W.F미만에서는 잔털(모우)제거 및 감량효과가 미약하며, 8% O.W.F초과시에는 잔털(모우) 제거효과는 있으나 인장강도 문제점이 발생할 수 있다.After the moso process, the fabric is subjected to enzyme reduction processing by treating it with an enzyme processing solution containing 3-8% O.W.F. of cellulase. Cellulase, the enzyme of the enzyme weight loss processing, removes hair from the surface of the modal fiber yarn, improves the lightness and soft feel of the cross fabric, and provides dimensional stability of the fabric shrinkage. There is almost no strength loss of the PLA fiber yarn, so the fabric The advantage is that it does not cause damage, has low weight loss, improves quality and maintains shape stability, and minimizes color pull and shade change from the fabric. In addition, there is no need to adjust the pH of the water, so there is a saving effect in process time, and because work can be done in a low temperature bath of about 40℃, the energy saving effect is high. The processing time is 15 to 60 minutes, and it is recommended to use 3 to 8% O.W.F. Below 3% O.W.F, the effect of removing fine hair and reducing weight is weak. If it exceeds 8% O.W.F., there is an effect of removing fine hair, but problems with tensile strength may occur.
상기 효소감량가공후에는 수세공정을 하여 본 발명의 모달―PLA 교직물의 친환경 효소가공방법을 완료하게 된다. 상기 수세공정은 통상적인 면직물의 수세공정과 동일하게 행할 수도 있으며, 보다 바람직하기로는 4차암모늄화합물 7~10중량%, Ethoxylated alcohol 2~4중량%, 1,2-Ethanediol 1~2중량% 및 잔부로서 증류수로 이루어진 섬유유연제 1~3중량%를 추가로 함유하는 수세액에서 수세하는 것이 억센 촉감을 가지는 PLA섬유사를 부드럽게 하여 전체 교직물의 촉감을 부드럽게 하고 드레이프성을 향상할 수 있어 바람직하다.After the enzyme reduction processing, a water washing process is performed to complete the eco-friendly enzyme processing method of the Modal-PLA cross fabric of the present invention. The washing process may be performed in the same way as the washing process of conventional cotton fabrics, and more preferably, 7 to 10% by weight of quaternary ammonium compound, 2 to 4% by weight of Ethoxylated alcohol, 1 to 2% by weight of 1,2-Ethanediol, and Washing in a washing solution additionally containing 1 to 3% by weight of a fabric softener consisting of distilled water as the remainder is preferable because it softens the PLA fiber yarns, which have a rough feel, to the touch of the entire fabric and improves drapability.
상기 섬유유연제의 4차암모늄화합물은 유연성을 증대시키는 작용을 하는 것으로서 트리에탄올 아민 에스테르 쿼트와 같은 것을 셀룰로오스 계통에 사용할 수 있는데, 7중량% 미만인 경우에는 유연성효과가 저하하며, 10중량%를 초과하면 유연제 잔류현상의 끈적거림 문제점이 발생할 수있다. Ethoxylated alcohol은 섬유유연제의 직물내로의 침투성을 향상하는 작용을 하며, 2중량%미만에서는 침투성이 저하하며, 4중량%를 초과하면 약간의 점성 문제점이 발생할 수 있다. 1,2-Ethanediol은 섬유 셀룰로오스 직물의 안정적인 촉감 작용을 하는 것으로서 1중량%미만에서는 안정성이 저하하며, 2중량%를 초과시 직물유연작용에 문제점이 발생할수있다.The quaternary ammonium compound in the fabric softener acts to increase flexibility, and something like triethanol amine ester quat can be used in cellulose systems. If it is less than 7% by weight, the flexibility effect decreases, and if it exceeds 10% by weight, the softener Residual stickiness problems may occur. Ethoxylated alcohol acts to improve the penetration of fabric softener into the fabric. If it is less than 2% by weight, the permeability decreases, and if it exceeds 4% by weight, some viscosity problems may occur. 1,2-Ethanediol provides a stable tactile effect for fibrous cellulose fabrics. If the content is less than 1% by weight, the stability decreases, and if it exceeds 2% by weight, problems may occur in the fabric softening effect.
그러므로 본 발명에 의하면, 친인체, 친환경소재인 모달섬유사 및 PLA사를 사용하여 제직한 모달―PLA 교직물의 친환경 효소가공방법에 의해 경량성, 부드러운 촉감 및 드레이프성을 향상시킴으로써 침구용 소재로 최적화된 교직물을 제공할 수 있으며, 세탁견뢰도 및 마찰견뢰도의 우수성(4~5급)이 확인되어 잠자리에서의 뒤척임이 잦거나 세탁회수의 증가에도 불구하고 형태안정을 유지할 수 있다.Therefore, according to the present invention, the lightweight, soft touch, and drape properties are improved by the eco-friendly enzyme processing method of the modal-PLA fabric woven using modal fiber yarn and PLA yarn, which are body-friendly and eco-friendly materials, and thus optimized as a bedding material. Excellent washing fastness and friction fastness (grade 4 to 5) have been confirmed, allowing shape stability to be maintained despite frequent tossing and turning in bed or an increase in the number of washings.
