이후, 상기 직물 또는 편물로 전처리단계, 후가공단계 및 열고정 단계를 행한다.Thereafter, a pre-treatment step, a post-processing step, and a heat setting step are performed on the woven or knitted fabric.
상기 전처리단계는 정련으로 이루어진다. Dope-Dyed 모다트릴(Modacryl)과 Spun-Dyed 셀룰로오스섬유로 이루어진 혼합방적사의 구성으로 진행시에는 염색공정단계가 생략된다.The pretreatment step consists of refining. The dyeing process step is omitted when proceeding with the composition of the mixed spun yarn composed of Dope-Dyed Modacryl and Spun-Dyed Cellulose fibers.
경우에 따라 상기 전처리단계는 모소, 정련표백, 머서화공정으로 이루어 질 수도 있다. 모소공정은 Speed 80m/min, 호발제 5g/L, Pick-up율 80%로 진행하며, 충분히 탈호를 시켜야 그라운드 염색시 불균염이 없다. 모소공정이 완료된 후 정련표백공정을 거치게 되는데 NaOH(50°Be') 0.9cc/L, 금속안정제 1g/L, H2O2 5g/L를 사용하여 원단에 손상이 적고 충분한 불순물을 제거한다. 머서화 공정은 원단에 장력을 주면서 견과 같은 광택과 염착성 향상, 치수안정화, 흡습성 증가, 강도의 향상을 도모할 수 있으나, 높은 알카리 처리시 오히려 원단을 손상시킬 수 있으므로 NaOH 7°Be'를 권장한다.Depending on the case, the pretreatment step may consist of a hair-burning, scouring bleaching, or mercerization process. The brushing process proceeds at a speed of 80m/min, a desizing agent of 5g/L, and a pick-up rate of 80%. Sufficient desizing is required to avoid uneven salting during ground dyeing. After the burning process is completed, it goes through a scouring bleaching process. NaOH (50°Be') 0.9cc/L, metal stabilizer 1g/L, H 2 O 2 Using 5g/L, there is little damage to the fabric and enough impurities are removed. The mercerization process gives tension to the fabric while improving nut-like luster, dyeability, dimensional stability, increased hygroscopicity, and strength. .
경우에 따라 염색공정을 추가할 수 있는데, 염색단계는 침염 또는 연속염색, 고착화의 순서로 진행한다. 전처리된 원단은 침염 또는 연속염색을 행하는데, 섬유의 손상 방지 및 Cost 절감을 위해 CPB 방식으로 하는 것이 바람직하다. Cellulose 소재 자체로는 일반 반응성 염료로도 충분히 견뢰도를 낼 수 있다.Depending on the case, a dyeing process can be added, and the dyeing step proceeds in the order of dip dyeing or continuous dyeing and fixation. The pretreated fabric is dyed or continuously dyed, and it is preferable to use the CPB method to prevent fiber damage and reduce cost. Cellulose material itself can achieve sufficient fastness even with general reactive dyes.
후가공단계에서는 텐타에서 Silicon계 유연제 20～30g/L, Hydrophilic 유연제 20～30g/L, 유연제로 인한 난연성 저하를 막기 위한 질소계 인산 난연제 20~30g/L 및 잔부로서 물을 함유한 처리액에 침지한다. 상기 열고정단계는 건열 온도 150~170℃에서 건조하게 된다.In the post-processing stage, 20~30g/L of silicon softener, 20~30g/L of hydrophilic softener, 20~30g/L of nitrogen-based phosphoric acid flame retardant to prevent deterioration of flame retardancy due to softener, and immersion in treatment liquid containing water as the balance in the tenta do. The heat setting step is dried at a dry heat temperature of 150 ~ 170 ℃.
