Description

미용타월용 복합사의 제조방법{Process Of Producing Composite Yarn For Bath―Towel}Technical Field [0001] The present invention relates to a composite yarn for a towel,

본 발명은 쐐기모양 날개단면부를 가지는 이형단면필라멘트를 가연하여 실크사와 함께 교락하여 닦임성 및 보습성을 가지는 미용타월용 복합사를 제조하는 방법에 관한 것이다.The present invention relates to a method for manufacturing a composite yarn for a cosmetic towel having a wiping cross-section and having a cross-section filament twisted together with a silk yarn to have a wiping property and a moisturizing property.

일반적으로 목욕시에 사용되는 목욕용 타월은 합성섬유사로 표면을 거칠게 직조한 타월이 주로 사용되고 있으나, 이는 우수한 피부 세정효과를 얻을 수 있음에 반하여 마찰을 위한 힘이 과다하게 필요하여 노약자나 영유아용으로는 부적합하였고, 지나친 마찰력으로 인해 피부손상을 유발시키는 문제점이 있다.Generally, a bath towel used for bathing is a synthetic fiber towel, which is roughly woven on the surface thereof. However, since it can obtain excellent skin cleansing effect, it requires excessive force for friction and is used for the elderly and infants There is a problem that it causes skin damage due to excessive frictional force.

따라서, 최근에는 목욕시 표면이 부드러운 수건이나 천 등을 사용하되, 피부 노폐물과 이물질을 쉽게 제거할 수 있는 바디 샴푸 등의 세정효과가 우수한 세제를 사용함으로써 목욕용 때밀이 타월에 의한 피부손상의 최소화를 도모하고 있는데 이 경우에도 수건이나 천 등의 조직 특성상 효과적인 이물질 제거가 어려운 문제점이 있었다.Therefore, in recent years, using a soft towel or cloth on the surface during bathing, but using a detergent having excellent cleaning effect such as a body shampoo which can easily remove skin wastes and foreign matter, minimizes skin damage caused by a bath- In this case, there is a problem that it is difficult to effectively remove foreign matter due to the nature of tissues such as a towel or cloth.

이러한 문제점을 해결하기 위해 대한민국특허공개제10-2006-0116073호에서는 경사는 0.001~0.1데니어의 폴리에스테르 초극세사들로 이루어진 폴리에스테르 멀티필라멘트 또는 그의 가연가공사이고, 위사는 0.001~0.1데니어의 폴리에스테르 초극세사들로 이루어진 폴리에스테르 멀티필라멘트 또는 그의 가연가공사와 비등수수축률이 10~50%인 폴리에스테르 멀티필라멘트(고수축사)와 폴리우레탄 섬유로 이루어진 복합사이며, 직물의 표면에 경사 축방향으로 양류형 굴곡들이 형성되는 것을 특징으로 하는 목욕용 직물을 제시하여 목욕용품으로 사용시 피부노폐물 제거성능이 매우 우수하고, 촉감이 쾌적하고, 피부에 자극이 적어 피부를 손상시키지도 않는 목욕용 직물을 제공하고 있다.In order to solve such a problem, Korean Patent Laid-Open Publication No. 10-2006-0116073 discloses a polyester multifilament made of polyester microfibers having a slope of 0.001 to 0.1 denier or a false-twisting process thereof, and the polyester fiber microfibers having a denier of 0.001 to 0.1 denier And polyester multifilament having a boiling water shrinkage ratio of 10 to 50% and a polyurethane fiber. The composite multifilament yarn is a composite yarn composed of polyester multifilament having a shrinkage ratio of 10 to 50% The present invention provides a fabric for a bath which is excellent in the ability to remove wastes from the skin when used as a bathing product, pleasant in touch, and less irritating to the skin, without damaging the skin.

그러나 이러한 초극세필라멘트를 제공하기 위하여는 특수한 방사구금이 필요할 뿐만 아니라 방사조건을 엄격하게 조절해야 하는 문제점이 있으며, 초극세사의 특성상 피부의 때를 효과적으로 제거하기가 어려운 문제점이 있어 때 미용타월로 사용하기에는 제한적인 실정이며 특히 이러한 합성섬유는 피부미용에 필수적인 보습효과가 없다.However, in order to provide such an ultrafine filament, there is a problem that a special spinning process is required and the spinning condition must be strictly controlled, and it is difficult to effectively remove the skin condition due to the characteristics of the microfibers. In particular, these synthetic fibers have no moisturizing effect that is essential for skin care.

우선, 쐐기모양 날개단면부를 가지는 이형단면PLA필라멘트(1)를 표면이 날카롭도록 하기 위해 가연하는데, 쐐기모양 날개단면부를 가지는 이형단면PLA필라멘트(1)를 도 1에 도시된 바와 같이 제1피드롤러(3)에 통과시키고 제1차히터(4)에서 열처리한 후, 마찰벨트 또는 디스크로 이루어진 가연장치(5)를 이용하여 가연하면서 제2피드롤러(6)를 통과시키면서 연신한다.First, the modified cross-section PLA filament 1 having the wedge-shaped wing cross-section is twisted to make the surface sharper. The modified cross-section PLA filament 1 having the wedge- Passes through the roller 3, is heat-treated in the first heater 4, and then stretched while passing through the second feed roller 6 while being twisted by using a twisting device 5 composed of a friction belt or a disk.

상기 쐐기모양 날개단면부를 가지는 이형단면PLA필라멘트는 도 3에 도시된 공정도와 같이, 단면이 십자형, '＊'형 및 'Ｙ'자형중 어느 하나의 형태인 이형단면 PLA필라멘트를 제1피드롤러를 통과시킨 후, 140∼170℃의 제1차히터에서 열처리한 후, 가연장치로 회전수 250~500 TPM, 장력비(T2/T1) 0.3 ∼ 0.7로 가연한 후, 마찰기구에 상기 이형단면 PLA필라멘트를 장력 0.4~0.7 g/d로 마찰시키면서 제2피드롤러를 통과시키면서 제1피드롤러와 제2피드롤러간의 속도차에 의해 연신비 1.2~1.3으로 연신한 후, 사속 250~350m/분으로 권취하여 제조된 쐐기모양 날개단면부를 가지는 이형단면PLA필라멘트인 것을 사용한다. The modified cross-section PLA filament having the wedge-shaped wing cross-section has a modified cross-sectional PLA filament having a cross-section of a cross shape, a '*' shape and a Y-shaped cross-section as a first feed roller After heat treatment at a first heater of 140 to 170 캜, the resin is twisted at a rotation speed of 250 to 500 TPM and a tensile ratio (T2 / T1) of 0.3 to 0.7 with a false twisting device. Thereafter, The filament is stretched at a stretching ratio of 1.2 to 1.3 by a speed difference between the first feed roller and the second feed roller while passing through the second feed roller while rubbing the filament at a tension of 0.4 to 0.7 g / Shaped cross section PLA filaments having wedge-shaped wing cross-sections.

도 3에서 도시된 바와 같이 쐐기모양 날개단면부를 가지는 이형단면PLA필라멘트는 원사인 이형단면 PLA필라멘트(21)를 제1피드롤러(22)를 통과시킨 후, 140∼170℃의 제1차히터(23)에서 열처리하는데, 실제로 가연장치(24)에서 발생된 트위스트는 열처리구간까지 연속되어 형성되는데, 상기 열처리에 의해 원사의 꼬임이 생긴 상태에서 원사가 연화하여 가공후 가공사의 비틀림이 유지될 수 있다. As shown in FIG. 3, a modified cross-section PLA filament having a wedge-shaped blade cross-section is obtained by passing a modified cross-section PLA filament 21, which is a source, through a first feed roller 22, The twist generated in the false twist device 24 is continuously formed up to the heat treatment section. The yarn is softened in a state where the yarn is twisted by the heat treatment, and the twist of the processed yarn after the processing can be maintained .

상기 열처리후에는 가연장치(24)로 회전수 250~500 TPM, 장력비(T2/T1) 0.3 ∼ 0.7로 가연하여 원사에 트위스트를 부여하여 가공사가 트위스트를 갖도록 하고 비틀림응력을 받게 한다. 상기 쐐기모양 날개단면부를 가지는 이형단면PLA필라멘트는 가연을 한 후, 마찰기구(25)에 상기 이형단면 PLA필라멘트를 장력 0.4~0.7 g/d로 마찰시켜 도 5에 도시된 바와 같이 원사의 단면끝부분이 변형을 일으키도록 한 것이다.After the heat treatment, twist is applied to the yarn by twisting the twisted yarn at a rotation number of 250 to 500 TPM and a tension ratio (T2 / T1) of 0.3 to 0.7 by the twisted yarn device 24 so that the twisted yarn has a twist and receives a torsional stress. As shown in FIG. 5, the modified cross-section PLA filaments having the wedge-shaped blade cross-section are twisted to friction mechanism 25 with the modified cross-section PLA filaments at a tension of 0.4 to 0.7 g / So that the part is deformed.

상기 쐐기모양 날개단면부를 가지는 이형단면PLA필라멘트는 140~170℃의 제1차히터(4)에서 열처리한 후, 마찰벨트 또는 디스크로 이루어진 가연장치(5)를 이용하여 가연비 1.4~1.6로 가연하면서 제2피드롤러(6)를 통과시키면서 연신비 1.2~1.3로 연신하는데, 제1차히터의 열처리온도가 140℃미만에서는 크림프형성이 낮은 문제점이 발생하며, 170℃를 초과하는 경우에는 이형단면PLA필라멘트의 날개단면부가 용융되어 촉감이 딱딱한 문제점이 발생한다. 가연비는 1.4~1.6이 바람직한데, 가연비 1.4미만에서는 크림프형성이 낮은 문제점이 발생하며, 1.6을 초과하는 경우에는 가연공정에서 사절이 발생한 문제점이 발생한다. 연신비 1.2미만에서는 복합사가 늘어나는 문제점이 발생하며, 1.3을 초과하는 경우에는 복합사가 끊어지는 문제점이 발생한다.The modified cross-section PLA filament having the wedge-shaped blade section is subjected to a heat treatment in a first heater 4 at 140 to 170 ° C, and thereafter is fired at a combustible ratio of 1.4 to 1.6 using a false- While the stretching ratio is 1.2 to 1.3 while passing through the second feed roller 6. When the heat treatment temperature of the first heater is less than 140 DEG C, a problem of low crimp formation occurs. When the temperature exceeds 170 DEG C, The wing section of the filament is melted and the touch is hard. The flammability ratio is preferably 1.4 to 1.6. If the flammable ratio is less than 1.4, a problem of low crimp formation occurs. If the flammability ratio exceeds 1.6, a problem of trimming occurs in the flammable process. If the stretching ratio is less than 1.2, there is a problem that the number of composite yarns increases, and when the stretching ratio is more than 1.3, the composite yarn is broken.

본 발명의 복합사의 다른 공급원사인 실크사(2)는 제3피드롤러(7)로 공급하여 상기 쐐기모양 날개단면부를 가지는 이형단면PLA필라멘트(1)와 함께 교락장치(8)에서 교락하게 된다. 상기 실크사는 함께 공급된 쐐기모양 날개단면부를 가지는 이형단면PLA필라멘트(1)와 함께 교락장치에서 교락되어 다층구조로 형성되는 현상을 이루게 되어 닦임성이 우수한 물성을 가지며, 실크사가 함유하고 있는 세리신성분의 보습효과로 인해 피부에 보습을 주어 미용에 도움을 줄 수 있는 복합사가 된다.The silk yarn 2, which is another source of the composite yarn of the present invention, is supplied to the third feed roller 7 to be entangled in the interlocking device 8 together with the modified cross-section PLA filament 1 having the wedge- The silk yarn is entangled in the interlocking device together with the modified cross-section PLA filament 1 having the wedge-shaped wing cross-section portion supplied thereto to form a multi-layered structure, so that the silk yarn has excellent physical properties such as cleanability, The moisturizing effect of the skin to moisturize and help the beauty can become a composite yarn.

It is preferred that the modified cross-section PLA filaments having the wedge-shaped wing cross-section are fed to the entanglement apparatus at an overfeeding rate of 4 to 6%, and the silk yarn is fed to the entanglement apparatus at an overfeeding rate of 1 to 2% If the overfeeding rate of the modified cross-section PLA filaments having a cross-sectional area of less than 4%, there is a problem that formation of a composite yarn is difficult. When the overfeeding rate exceeds 6%, formation of a multi-layered structure becomes difficult. When the overfeeding rate of the silk yarn is less than 1%, it is difficult to form a composite yarn. When the overfeeding rate is more than 2%, the stability of the yarn is decreased and formation of a multilayered structure becomes difficult.
