現今社會對於健康保健逐漸提高重視，也造成了運動的興盛，許多專業的運動因為是高強度及高伸展的運動，為了因應這些需求，許多廠商將製作運動布料複合的彈性纖維含量增加，達到衣物所需的貼身度。當尼龍6.6織物裡含有高含量的彈性纖維時，使用酸性螢光染料染色以及配合其他酸性染料進行複合調色，布面易產生不均染，並在現場大量染色時布面色光不一致的問題，並在染後色牢度不佳達不到客戶的要求等問題發生，進而影響公司的品質控管及耽誤出貨的時間。
本實驗挑出兩種不同含量的彈性纖維之尼龍織物11%及25%進行染色並以不含彈性纖維0%之純尼龍作為基準，使用螢光紅色系的酸性染料配合其他酸性染料進行複合染色，在染色過程中先加入不同離子類型的均染劑及不同濃度染出的樣布，使用 Datacolor分光儀分析布面表觀力度K/S值及布面色光變異，另觀察均染劑對於織物於染色後的均染性，評估高含量彈性纖維之尼龍織物使用酸性紅色螢光染料染色適用於哪一種離子類型的均染劑，以前面的最佳的條件下，再做不同類型的固色劑處理，同時也分別採用三種紫外線吸收劑以提昇日光牢度，經過了這些條件的組合下即能找出最佳染色條件，以期能改善公司的染色異常狀況，同時對織物之光退色變化率進行探討。
在實驗的結果最後，我們發現了在使用陰離子型均染劑可使螢光紅酸性染料達到最佳均染效果，且搭配陰離子型固色劑可有效改善織物的水洗、耐水、耐汗的染色牢度，若搭配使用紫外線吸收劑將使日光牢度明顯提升，確實可達到客戶端的要求。
In order to emphasis on health care, the functional sportswere had been gradually increased. The many professional sports demand high-intensity and high-stretch for sportswere, the nylon 6.6 fabrics contained high amounts of elastic fibers were needed. When high elastic nylon 6.6 dyed with fluorescent acid dye mixed with other acid dye, the uneven surface, color difference and lower colorfastness with be easy to appear.
In this experiment, 11% and 25% of the nylon fabrics with different content of elastic fibers were used and dyed, and the fluorescent red acid dyes were mixed with other acid dyes for this. The fluorescent red mixed with other acid dye was used to study the influence of leveling and fixing agents on the color strength(K/S), levelness, colorfastness colordifference(ΔE) and photorating phenomenon of dyed high elastic nylon 6.6 fabrics.
From results shown the use of anionic leveling agent can achieve the best leveling effect of fluorescent red acid dyes, and with anionic fixing agent can effectively improve the washing, water and sweat resistance of fabrics. Additionally, if used in conjunction with UV absorbers will significantly increase the light fastness, can indeed meet the client's requirements.
