벌키성 지지부재를 구비한 인조잔디의 제조방법{MANUFACTURING METHOD OF ARTIFICIAL TURF WITH BULKY SUPPORT}MANUFACTURING METHOD OF ARTIFICIAL TURF WITH BULKY SUPPORT}

본 발명은 인조잔디의 제조방법에 관한 것이며, 보다 상세하게는 주엽을 지지하는 지지부재를 구비하는 인조잔디의 제조방법에 관한 것으로, 지지부재는 주엽보다 낮은 융점과 연화점의 열특성을 지닌 소재를 사용하고 열처리를 통하여 벌키화시킴으로서 주엽을 지지하는 지지부재를 구비하는 인조잔디의 제조방법에 관한 것이다.
The present invention relates to a method for producing artificial turf, and more particularly, to a method for manufacturing artificial turf having a support member for supporting a main leaf, the support member is a material having a lower melting point and a softening point than the main leaf material The present invention relates to a method for producing artificial turf having a support member for supporting a main leaf by bulking through heat treatment.

인조잔디는 사용중 수회 눌렸을 때 천연잔디와는 다르게 자연적으로 회복되지 않으므로 내구성에 취약한 문제가 있다.Artificial turf is vulnerable to durability because it does not recover naturally unlike natural grass when pressed several times during use.

이 문제를 개선하기 위하여 인조잔디에 규사나 고무칩 등의 충진재를 포설하여 인조잔디를 지지하고 충격흡수제로서 사용을 하고 있으나 이런 지지부재는 고정되어있지 않으므로 유동성에 의해 유실되는 경우가 많아 정기적인 보충을 필요로 하고 환경오염 등의 문제도 유발하였다. In order to improve this problem, the fillers such as silica sand or rubber chips are installed on the artificial turf to support the artificial turf and use it as a shock absorber. However, since these supporting members are not fixed, they are often lost due to fluidity. It also caused problems such as environmental pollution.

본 발명은 주엽(10)을 지지하기 위한 지지체로서 추가적인 소재의 지지부재(20)를 형성되는데, 열처리를 통하여 터프트파일(30)의 지지부재소재(21)를 연화점 이상의 온도에 노출시킴으로서 지그재그형상의 벌키성 요철구조를 형성되어, 주엽(10)을 지지하고 굽힘회복성을 향상시켜 전체적인 인조잔디(2)의 내구성이 좋아지며 또한, 지지부재(20) 자체가 인조잔디(2)로서의 탄성체 역할을 하여 품질을 한층 더 향상시키게 된다.       The present invention forms a support member 20 of an additional material as a support for supporting the main lobe 10, the zigzag shape by exposing the support member material 21 of the tuft pile 30 to a temperature above the softening point through heat treatment. By forming the bulky irregularities of the structure, supporting the main leaf 10 and improving the bending recovery properties, the overall durability of the artificial turf 2 is improved, and the support member 20 itself serves as an elastic body as the artificial turf 2. To further improve the quality.

즉 본 발명은 주엽(10)과 이를 지지하기 위한 한 개 이상의 소재로써 구성된 지지부재(20)로 구비되는 인조잔디(2)인데, 지지부재(20)는 주엽(10)에 비하여 융점과 연화점이 낮은 소재를 사용하여 주엽(10)과 같이 제직하고 열처리하여 지지부재(20)를 벌키성을 띠게 함으로서 주엽(10)의 지지부재(20)가 된다.       That is, the present invention is artificial turf (2) is provided with a main leaf 10 and a support member 20 composed of one or more materials for supporting the same, the support member 20 is melting point and softening point compared to the main leaf 10 Weaving and heat-treating like the main leaf 10 using a low material to make the support member 20 bulky, becomes the support member 20 of the main leaf 10.

벌키성(bulkiness)은 지지부재(20)를 가온하여 지그재그형상의 요철구조로 형성시킴으로서 부푼 형상의 부품성을 의미한다.
Bulkyness refers to a bulge-like part by heating the support member 20 to form a zigzag uneven structure.

실시예 1의 주엽(10)의 재료는 나일론과 폴리에틸렌인데 기본물성은 표 1과 같다.
The material of the main leaf 10 of Example 1 is nylon and polyethylene but the basic physical properties are shown in Table 1.

폴리에틸렌(PE)은 제조방법에 따라 LDPE(Low density poly-ethylene), LLDPE(linear low density poly-ethylene)와 HDPE(High density poly-ethylene)로 구분되는데, Polyethylene (PE) is classified into low density poly-ethylene (LDPE), linear low density poly-ethylene (LLDPE) and high density poly-ethylene (HDPE) according to the manufacturing method.

HDPE는 고밀도 폴리에틸렌으로서 밀도가 높고 강도가 세며, LDPE는 저밀도 폴리에틸렌으로서 HDPE에 비하여 밀도가 낮고 강도가 약하지만 HDPE에 비하여 상대적으로 부드럽고, LLDPE는 선형 저밀도 폴리에틸렌으로서 LDPE와 밀도도 같고 부드럽지만 강도는 LDPE와 HDPE의 중간인데, 폴리에틸렌은 전반적으로 유연성이 좋고 자체적으로 부품성의 특성인 벌키성(bulkiness)이 좋다. HDPE is a high density polyethylene with high density and high strength.LDPE is a low density polyethylene with lower density and weaker strength than HDPE but relatively softer than HDPE. Intermediate between and HDPE, polyethylene is generally flexible and has its own bulkyness, which is part-specific.

나일론은 대표적인 엔지니어링 플라스틱 중의 하나로서, 폴리에틸렌에 비하여 융점과 연화점이 높고 내마모성과 강도가 우수하며 굽힘회복성 또한 범용수지 중 가장 우수하여 인조잔디(2)의 소재로서 많은 장점이 있지만, 부드럽고 풍만한 느낌의 부품성을 주는 벌키성은 폴리에틸렌보다 떨어지는 단점이 있다.
Nylon is one of the representative engineering plastics. It has higher melting point and softening point, better wear resistance and strength, and better bending recovery than general-purpose resins, so it has many advantages as artificial grass (2). The bulkiness giving the part has a disadvantage that it is inferior to polyethylene.

도 2는 나일론 중의 하나인 나일론6를 주엽소재(11)의 주재료로 하고 폴리에틸렌인 LDPE, LLDPE와 HDPE의 조성물로 구성되어 방사되는 PE모노필라멘트를 지지부재소재(21)의 주재료로서 벌키화하여, 주엽(10)의 지지부재(20)로 하는 벌키성 지지부재를 구비한 인조잔디(2)의 제조공정도이다.    2 is a bulk material of nylon 6, which is one of nylon, as the main material of the main leaf material 11, and the PE monofilament, which is composed of the composition of LDPE, LLDPE and HDPE, which is polyethylene, is spun as the main material of the support member material 21, It is a manufacturing process diagram of the artificial turf 2 provided with the bulky support member used as the support member 20 of the main leaf 10. As shown in FIG.

벌키성 지지부재를 구비한 인조잔디(2)의 제조를 위한 과정은 다음과 같다.
Process for the manufacture of artificial turf (2) having a bulky support member is as follows.

주엽소재(11)의 주재료인 나일론6에 첨가되는 첨가제로서 착색제인 마스터배치와 UV차단제를 용융압출기의 호퍼에 같이 투입하여 나이론6의 융점인 220도 이상의 온도에서 용융하고 압출한 후 정밀한 토출이 가능한 기어펌프에 의해 인조잔디(2) 단면형상인 성형노즐을 통하여 방사하여 주엽소재(11)를 형성한다.    As an additive added to nylon 6, the main material of the main leaf material 11, a masterbatch and a UV blocking agent, which are colorants, are put together in the hopper of the melt extruder, melted and extruded at a temperature of 220 degrees or more, which is the melting point of nylon 6, and then precisely discharged. The main leaf material 11 is formed by spinning through a molding nozzle having a cross section of artificial turf 2 by a gear pump.

주엽소재(11)는 100중량% 기준으로 나일론6 88~92중량%, 마스터배치혼합물 8~12중량%를 포함하는데, 마스터배치혼합물은 100중량%기준으로 마스터배치와 UV차단제를 각각 30~70중량%의 비율로 한다.
The main leaf material (11) is based on 100% by weight of nylon 6 88 ~ 92% by weight, the master batch mixture 8 to 12% by weight, the master batch mixture is based on 100% by weight of the master batch and UV blocker 30 to 70, respectively It is made into the ratio of weight%.

지지부재소재(21)의 주재료인 폴리에틸렌도 첨가제인 마스터배치, UV차단제와 같이 호퍼에 투입하고 폴리에틸렌 중 융점이 제일 높은 HDPE의 융점인 135도 이상의 온도로 가온하여 용융하고 압출한 후 기어펌프의 노즐을 통하여 방사하여 PE모노필라멘트로 성형한다.Polyethylene, which is the main material of the support member material 21, is added to a hopper like an additive, a masterbatch and a UV blocking agent, and heated and melted at a temperature of 135 degrees or more, which is the melting point of the HDPE having the highest melting point among polyethylene, and extruded. It is spun through and molded into PE monofilament.

각 성분별 조성비는 PE조성물 100중량%를 기준으로 LDPE 14.3~26.3중량%, LLDPE 52.4~68.4중량%, HDPE 14.3~26.3중량%로 하고 첨가제인 마스터배치혼합물 100중량% 기준으로 마스터배치와 UV차단제는 각각 30~70중량%의 비율로 한다.
The composition ratio of each component is based on 100% by weight of PE composition, LDPE 14.3 ~ 26.3% by weight, LLDPE 52.4 ~ 68.4% by weight, HDPE 14.3 ~ 26.3% by weight, and masterbatch and UV blocker based on 100% by weight of master batch mixture as an additive. The ratio is 30 to 70% by weight, respectively.

방사된 주엽소재(11)와 지지부재소재(21)를 혼섬하여 복합원사(1)를 생성하고 상온수의 저온욕조에 침지하여 안정화하고 고온욕조의 고온침지유에 침지하여 유연제와 대전방지제 처리를 하는데, 고온침지유는 100중량%기준으로 유연제 5~10중량%, 대전방지제 5~10중량%와 물 85~90중량%를 포함한다.Mixing the spun leaf material 11 and the support member material 21 to produce a composite yarn (1), stabilizes by immersing in a low-temperature bath of normal temperature water, and immersed in a high-temperature immersion oil of a high temperature bath to process the softener and antistatic agent, High temperature immersion oil contains 5 to 10% by weight softener, 5 to 10% by weight of antistatic agent and 85 to 90% by weight of water based on 100% by weight.

고온침지된 복합원사를 1:4.5~5.5로 연신하여 분자구조를 결정화함으로서 강도를 증가시키고, 연신 후 방치에 의한 자연수축인 풀림공정을 거쳐서 섬도를 확정한 후 권취한다.
The high temperature immersed composite yarn is stretched from 1: 4.5 to 5.5 to crystallize the molecular structure to increase the strength, and after drawing, the fineness is determined and wound up after winding.

권취된 복합원사(1)를 바탕직물(40)에 제직하여 터프트파일(30)을 형성하는데 터프트파일(30)은 제직 후 바탕직물(40)의 상부측에 놓이는 실질적인 인조잔디(2)로서 역할을 하는 부분이다. Weaving the wound composite yarn 1 on the base fabric 40 to form a tuft pile 30, the tuft pile 30 is a practical artificial grass (2) placed on the upper side of the base fabric 40 after weaving It is part that serves as.

제직 후 바탕직물(40)의 이면에는 터프트파일(30)을 바탕직물(40)에 단단하게 고정하기 위한 백코팅공정에서 접착제 역할의 라텍스(41)를 도포하고 건조하는데, 건조열처리기는 라텍스의 건조와 터프트파일(30)의 지지부재소재(21)에 열처리를 동시에 하므로 라텍스건조온도와 열처리온도를 병행하기 위하여 100℃ 이상으로 한다. After weaving, the backside of the base fabric 40 is coated and dried with an adhesive latex 41 in a back coating process for firmly fixing the tuft pile 30 to the base fabric 40. Since the drying and the heat treatment to the support member material 21 of the tuft pile 30 at the same time to be at least 100 ℃ in order to parallel the latex drying temperature and the heat treatment temperature.

본 발명의 건조열처리기에서 수행되는 열처리는 주엽(10)의 벌키성 지지부재(20)를 형성하는 매우 중요한 공정으로서, 지지부재소재(21)인 PE모노필라멘트를 구성하고 있는 LDPE, LLDPE와 HDPE의 융점과 연화점의 차이를 이용하여 벌키성을 띠게 하는 벌키화공정의 핵심이다.
The heat treatment performed in the dry heat treatment apparatus of the present invention is a very important process for forming the bulky support member 20 of the main leaf 10, and the LDPE, LLDPE and HDPE constituting the PE monofilament, the support member material 21. It is the key to the bulky process that makes bulky by using the difference between melting point and softening point.

상기 표 1 나타난 PE모노필라멘트의 구성성분 각각의 융점과 연화점 차이를 이용하여 지지부재소재(21)를 지그재그 형상의 요철형으로 하는 벌키성을 부여하게 되는데, 연화점이란 고체상태인 플라스틱에 온도를 가함에 따라 VICAT 연화점(이하 연화점) 을 지나면서 액상화기 시작하는 전이온도로 플라스틱의 기계적 강도가 급격하게 저하되기 시작하는 온도이다.Using the difference between the melting point and the softening point of each of the constituents of the PE monofilament shown in Table 1, the support member material 21 is given a bulky property in the form of a zigzag shape. The softening point is applied to a plastic in a solid state. This is the temperature at which the mechanical strength of the plastic begins to drop sharply as it transitions to the liquefaction point after passing through the VICAT softening point (hereinafter softening point).

표 1에 나타나는 PE모노필라멘트의 구성성분의 연화점의 범위는 LDPE : 83~94℃, LLDPE : 92~103℃, HDPE: 124~126℃ 이므로 벌키화를 위한 열처리온도 범위는 83~123℃이지만, 상기 라텍스의 건조와 같이 병행하기 위하여 온도를 100~123℃로 한다. The softening point range of the components of PE monofilament shown in Table 1 is LDPE: 83-94 ° C, LLDPE: 92-103 ° C, HDPE: 124-126 ° C, so the heat treatment temperature range for bulking is 83-123 ° C. The temperature is set to 100 to 123 ° C. in parallel with drying of the latex.

열처리온도를 HDPE의 연화점보다 낮은 온도로 하는 이유는 열처리시 HDPE가 지지부재소재(21)인 PE모노필라멘트의 최소한의 선형구조를 유지하게 하기 위함이고, 이로서 지지부재소재(21)의 부품성인 벌키성이 뛰어난 벌키화가 이루어진다. The reason why the heat treatment temperature is lower than the softening point of the HDPE is that the HDPE maintains the minimum linear structure of the PE monofilament, which is the support member material 21 during the heat treatment, thereby punishing the component properties of the support member material 21. It is bulky with excellent height.

나일론6의 연화점은 142℃로 PE조성물에 비하여 훨씬 높으므로 열처리에 의한 영향을 받지 않고 인조잔디(2)의 주엽(10)으로서 역할을 한다.
Since the softening point of nylon 6 is much higher than that of PE composition at 142 ° C., it acts as the main lobe 10 of the artificial turf 2 without being affected by heat treatment.
