Description

촉감 및 벌키성이 우수한 이수축 복합사.A biaxial composite yarn with excellent touch and bulkiness.

본 발명은 촉감 및 벌키성이 우수한 이수축 복합사에 관한 것이다.The present invention relates to a biaxial composite yarn having excellent touch and bulkiness.

본 발명의 이수축 복합사는 주로 촉감 및 벌키성이 우수한 원단제조에 사용된다. 지금까지는 주로 저수축사와 고수축사를 공기교락에 의해 혼섬처리한 이수축 혼섬사를 사용하여 촉감 및 벌키성이 우수한 원단을 제조해오고 있다. 이때 고수축사(심사)로는 고배향 미연신사가 주로 사용되며 저수축사(효과사)로는 해도형 또는 분할형 복합사가 주로 사용된다. 이와 같이 고수축사(심사)와 저수축사(효과사)를 공기혼섬한 이수축 혼섬사로 제조된 원단은 열처리 공정에서 저수축사와 고수축사의 수축차를 발현되기 때문에 촉감 및 벌키성이 향상된다. 그러나 상기 종래 방법은 다음과 같은 여러 문제점이 있다.Bi-shrink composite yarn of the present invention is mainly used for fabrication of excellent touch and bulkiness. Up to now, it has been manufacturing fabrics with excellent feel and bulkiness using bi-shrink blended yarns, in which low-shrink yarns and high-shrink yarns are blended by air entanglement. At this time, the highly oriented unstretched yarn is mainly used as the high shrink yarn (examination), and the island-in-the-sea or split composite yarn is mainly used as the low shrinkage yarn (effect yarn). In this way, the fabric made of bi-shrink blended yarn in which the high shrink yarn (examination) and the low shrink yarn (effect yarn) are air-mixed expresses the shrinkage difference between the low shrink yarn and the high shrink yarn in the heat treatment process, thereby improving the feel and bulkiness. However, the conventional method has several problems as follows.

첫째, 양호한 제직 공정성을 위하여 저수축사와 고수축사를 높은 공기압력으로 혼섬해야 하기 때문에 혼섬시 형성된 교락점 중 일부가 염색후에도 풀리지 않아 염반이 발생한다.First, because good weaving process needs to interweave low and high shrink yarns with high air pressure, some of the entanglement points formed during blending do not loosen after dyeing, causing salt spots.

둘째, 저수축사 및 고수축사를 각각 별도의 공정으로 제조한 후, 이들을 또다른 공정으로 혼섬해야 하기 때문에 제조공정이 복잡하고 제조비용이 높다.Second, since the low shrinkage yarn and the high shrinkage yarn are manufactured in separate processes, they must be mixed with another process, and thus the manufacturing process is complicated and manufacturing costs are high.

셋째, 심사인 고수축사가 고배향 미연신사이기 때문에 일반 연신사인 경우에 비해 원사 제조공정상 불량률이 높고, 후가공시 장력 및 열처리온도가 조금만 불균일해도 쉽게 원사변형이 일어나 공정통과성이 저하된다.Third, because the high shrink yarn, which is the screening yarn, is highly oriented and unstretched, the defect rate is higher in the yarn manufacturing process than in the case of general stretched yarn.

넷째, 효과사인 저수축사 극세섬유이기 때문에 공기교락 공정의 조건을 설정하기 어렵다.Fourth, it is difficult to set the conditions of the air entanglement process because it is a low-shrink yarn microfine fiber, which is an effect yarn.

다섯째, 비록 원사 상태에서는 고수축사와 저수축사의 수축율 차이가 크다고 해도 원단 상태에서는 원단 조직에 의한 장력이 발생하므로 고수축사와 저수축사의 수축차가 충분하게 발현되기 어렵다.Fifth, although the shrinkage difference between the high shrink yarn and the low shrink yarn in the yarn state is large, it is difficult to sufficiently express the shrinkage difference between the high shrink yarn and the low shrink yarn because the tension is caused by the fabric structure in the fabric state.

본 발명은 제직 등의 공정통과성이 우수함과 동시에 원단제조시 제조된 원단의 촉감 및 벌키성이 우수하며 염반이 발생되지 않는 이수축 복합사를 간단한 공정으로 제조하고자 한다.The present invention is to produce a bi-shrink composite yarn in a simple process that is excellent in the process passability such as weaving and the like and excellent in the touch and bulkiness of the fabric produced during fabric manufacturing.

본 발명은 원단제조시 제조된 원단의 촉감 및 벌키성이 우수한 이수축 복합사에 관한 것이다. 더욱 구체적으로 본 발명은 아래 식(Ⅰ)의 수축 특성을 만족하며 서로 비상용성인 저수축 분절(1)과 고수축 분절(2)로 구성되며, 원사 단면상에서 상기 저수축 분절(1)들이 고수축 분절 사이사이에 위치하는 것을 특징으로 하는 촉감 및 벌키성이 우수한 이수축 복합사에 관한 것이다.The present invention relates to a biaxial composite yarn excellent in the touch and bulkiness of the fabric produced during fabric production. More specifically, the present invention consists of a low shrinkage segment (1) and a high shrinkage segment (2) which are incompatible with each other and satisfy the shrinkage characteristic of the following formula (I), wherein the low shrinkage segments (1) are high shrinkage on a yarn cross section. The present invention relates to a biaxially conjugated composite yarn excellent in touch and bulkiness, which is located between segments.

1.5 ≤ ≤ 5.0 (Ⅰ)1.5 ≤ ≤ 5.0 (Ⅰ)

이하 본 발명을 상세하게 설명하기로 한다.Hereinafter, the present invention will be described in detail.

도 1은 본 발명 이수축 혼섬사의 분할전 단면도이고 도 2는 본 발명 이수축 혼섬사의 분할후 단면도이다.1 is a cross-sectional view before dividing the biaxial mixed fiber of the present invention, Figure 2 is a cross-sectional view after dividing the biaxial mixed fiber of the present invention.

본 발명의 이수축 복합사는 서로 비상용성인 저수축 분절(1)과 고수축 분절(2)로 구성된다. 이때 상기 저수축 분절(1)들은 도면과 같이 원사 단면상에서 고수축 분절(2) 사이사이에 위치한다.The bishrink composite yarn of the present invention is composed of a low shrink segment 1 and a high shrink segment 2 which are incompatible with each other. In this case, the low shrink segments 1 are located between the high shrink segments 2 on the yarn cross section as shown in the figure.

상기 저수축 분절(1)과 고수축 분절(2)은 아래 식(Ⅰ)과 같은 수축 특성을 만족한다.The low shrinkage segment (1) and the high shrinkage segment (2) satisfy the shrinkage characteristics as shown in Equation (I) below.

1.5 ≤ ≤ 5.0 (Ⅰ)1.5 ≤ ≤ 5.0 (Ⅰ)

또한 저수축 분절의 비등수 수축율(S1)은 3∼30%, 고수축 분절의 비등수 수축율(S2)은 10∼50%인 것이 더욱더 바람직하다. 전체 이수축 복합사의 단면적에 대한 저수축 분절(1)의 단면적 비는 50∼90%인 것이 바람직하다. 저수축 분절(1)의 단면적 비가 상기 범위를 벗어나는 경우에는 저수축 분절이 원단 표면으로 부출되는 효과가 저하되어 촉감 및 벌키성이 저하된다. 저수축 분절로는 폴리아미드가 주로 사용될 수 있고, 고수축 분절로는 폴리에틸렌글리콜(PEG), 디메틸-5-술포이소프탈레이트(DMIS) 및/또는 이소프탈릭 액시드(IPA) 가 공중합된 공중합 폴리에스테르가 사용될 수 있다. 저수축 분절은 섬도 0.5데니어 이하로 극세화하는 것이 촉감 향상 등에 바람직하다.The boiling water shrinkage ratio S 1 of the low shrinkage segment is more preferably 3 to 30%, and the boiling water shrinkage ratio S 2 of the high shrinkage segment is 10 to 50%. It is preferable that the cross-sectional area ratio of the low shrinkage segment 1 with respect to the cross-sectional area of all the biaxially-composite composite yarns is 50 to 90%. When the cross-sectional area ratio of the low shrinkage segment 1 is out of the above range, the effect that the low shrinkage segment is blown out to the fabric surface is lowered, resulting in deterioration of touch and bulkiness. Polyamide may be mainly used as the low shrink segment, and copolymerized poly-polymer copolymerized with polyethylene glycol (PEG), dimethyl-5-sulfoisophthalate (DMIS) and / or isophthalic acid (IPA) Ester may be used. The low shrinkage segment is preferably made finer at a fineness of 0.5 denier or less to improve the feel and the like.

본 발명의 이수축 복합사는 상기 저수축 분절용 폴리머와 고수축 분절용 폴리머를 통상의 분할형 복합방사 장치에서 복합방사하여 제조할 수 있다. 본 발명의 이수축 복합사를 사용하여 직물을 제직한 후 정련, 감량, 열고정, 염색, 파이날 세트 공정으로 최종 가공지를 제조한다. 이수축 혼섬사의 감량은 물리적 마찰방법이나 화학적인 용해방법으로 실시할 수 있다.The bi-shrink composite yarn of the present invention can be produced by complex spinning the polymer for low shrink segment and polymer for high shrink segment in a conventional split composite spinning device. After weaving the fabric using the biaxially conjugated composite yarn of the present invention, the final processed paper is manufactured by refining, weight loss, heat setting, dyeing, and final set processes. Reduction of the biaxially blended yarn can be carried out by a physical friction method or a chemical dissolution method.

본 발명의 이수축 복합사는 상기 정련 및 감량 공정에서의 고수축 분절과 저수축 분절의 비등수 수축율 차이와 열고정 및 파이날 세트 공정에서의 고수축 분절과 저수축 분절의 잔류 수축율 차이에 의해 이수축 혼섬 효과가 발현하게 된다. 감량공정에서 고수축 분절과 저수축 분절이 분할된 후 이들의 비등수 수축율 및 잔류 수축율 차이에 의해 저수축 분절들은 원단 표면으로 부출되고, 고수축 분절은 수축되어 원단 이면에 위치하게 된다. 그 결과 고수축 분절과 저수축 분절은 혼섬 공정없이 자연스럽게 혼섬되어진다. 이와 같이 극세사인 저수축 분절들이 원단 표면으로 부출되기 때문에 원단의 촉감이 향상됨과 동시에 자연스러운 혼섬 효과에 의해 원단의 벌키성도 향상된다. 특히 고수축 분절의 형태가 다형 단면이기 때문에 혼섬의 효과는 더욱 양호하게 된다. 또한 본 발명의 이수축 복합사는 공기교락에 의한 교락점이 없기 때문에 염색시 염반이 발생되지 않아 원단의 품질이 향상된다.The bishrink composite yarn of the present invention shrinks due to the difference in boiling water shrinkage ratio between the high shrinkage segment and the low shrinkage segment in the refining and reducing process and the residual shrinkage difference between the high shrink segment and the low shrink segment in the heat setting and final set process. The blending effect is expressed. After the high and low shrinkage segments are divided in the weight loss process, the low shrinkage segments are ejected to the fabric surface by the difference in boiling water shrinkage and residual shrinkage ratio, and the high shrink segments are contracted and placed behind the fabric. As a result, the high and low shrink segments are naturally blended without the blending process. As the microfiber low-shrink segments are blown onto the fabric surface, the texture of the fabric is improved and the bulkiness of the fabric is also improved by the natural blending effect. In particular, since the high shrinkage segment has a polymorphic cross section, the effect of the blend is better. In addition, since the biaxially conjugated composite yarn of the present invention does not have an entanglement point due to air entanglement, no dyeing occurs during dyeing, thereby improving the quality of the fabric.
