피혁에 사용되는 염료의 종류와
특징을 설명해 주세요
Q
드럼염색에 사용하는 것은 원칙적으로 음이온염료입니다. 통상은 산성염료, 직접염료가 주로 사용된다. 이 양자는 혁의 염색에 사용될 경우, 천의경우처럼 본질적인 차이점은 없고, 어느 쪽도 혁의 산성이 강하면(크롬함량이 큰 경우도 해당)흡수가 빠르고, 표면에 진하게 염색되는 경향이 있습니다. 그러나 일반적으로는 직접염료쪽이 이러한 경향이 강하다. 색조도 약간은 칙칙하다. 양쪽 다 혁의 중화가 강하고, 또한 합성유제 등으로 재유가 많이 되어 있을수록 연한색으로 되는 경향이 있고, 또한 알카리성이 강하게 되면 색이 떨어지는 경향이 있습니다.
함금염료(含金染料)라는 것은 이러한 혁의 산성도에 의해 염착성이 변동하는 경향이 비교적 적고, 따라서 세척견뢰도가 좋고, 내광성도 좋지만 선명한 색조의 것이 적습니다. 반응염료도 산성으로써 혁에 염색되지만, 그 후 알카리에서 처리하면 특수한 화학반응이 있으나, 혁과의 결합이 강고해지고(염료가 고착된다) 세척 견뢰도가 현저히 향상되는 점이 특징입니다. 그러나 고착되지 않고 혁으로부터 용탈되는 염료가 많아서 진한색을 얻기 힘듭니다. 크롬혁은 알카리에 약하므로 이러한 형태의 염료 특징을 발휘하기가 어렵습니다.
이상의 염료와는 전기적으로 정반대인 염기성염료도 약간 사용됩니다. 이러한 염료는 색조가 아주 선명하고 깊지만, 마찰 등에 의해 색이 발하고, 햇빛에 퇴색이 잘되므로 단독으로는 사용치 않습니다. 예로 검정 스웨이드혁에서 색에 깊이를 주기위해 직접염료와 조합하여 샌드위치 염색합니다.
그 외 수용성 황화염료, 건염염료(建染染料)는 착색한 후 적당한 조건에서 산화하면 견뢰도가 향상됩니다. 작용이 강한 화학약품을 필요로 하는 경우가 많기 때문에 혁에서는 특수한 경우에만 사용됩니다.

MMOexp：College Football 25: A Mixed Review
With the release of College Football 25 Coins, excitement was high among fans, some even going so far as to invest in new consoles just to get their hands on the game. As a long-time football video game enthusiast, I have experienced both highs and lows with this latest installment. While College Football 25 excels in on-field action and presentation, several off-field issues diminish the overall experience. Here’s a detailed look at what works, what doesn’t, and what might be improved.
On-Field Excellence
College Football 25 stands out with its impressive graphics and gameplay. EA Orlando has clearly put significant effort into making the on-field action as realistic and engaging as possible. The visuals are striking—players’ sweat, exceptional lighting, and detailed animations all contribute to a more immersive experience. Unique team intros, mascot celebrations, and cheerleader performances add to the game's personality, capturing the essence of college football's pageantry and tradition.
Gameplay has also seen notable improvements. The game runs faster and smoother than its predecessors, with quicker plays and more nimble player movements. The revamped passing system offers a learning curve but rewards precision with a better mix of throw arc and accuracy. For those preferring the familiar Madden controls, they are still available. Throw power now impacts ball speed and force, while pump fakes have been enhanced for more realistic play.
The addition of new features, such as 12 hot route options for receivers and improved custom stem options, further enriches gameplay. A small but significant quality of life change allows the game to automatically run down the clock when taking a knee in a mathematically over game.
Underwhelming Modes and UI Issues
Despite the strong on-field performance, College Football 25 falters significantly with its modes and user interface. The game offers several modes, including Play Now, Road to the College Football Playoffs, Road to Glory, Dynasty, and College Ultimate Team. However, many of these modes feel underdeveloped and lack depth.
The UI, in particular, is a major disappointment. Key information about player wear and tear and stamina is poorly displayed, often making it hard to discern what’s happening on the field. The automated hat count from Madden is missing, and stamina indicators are represented by small, unclear icons. The UI issues extend to the in-game commentary and bugs, such as persistent hot spots in drills and inaccurate commentary, which detract from the overall experience.
Road to Glory, while offering some fun with mini-games and player progression, becomes repetitive quickly. The lack of meaningful in-game cutscenes and limited play call options can make playing as a quarterback feel restrictive and frustrating.
Dynasty mode, a highlight for many, also falls short. It offers a decent foundation for managing a team and recruiting players but becomes tedious due to its repetitive nature. The absence of direct player management or training makes the mode feel more like a series of menu tasks rather than an engaging coaching experience.
Ultimate Team and Tutorials
College Football 25’s focus on Ultimate Team, with its emphasis on microtransactions and slot machine mechanics, is a major point of contention. The replacement of the skills trainer with Ultimate Team challenges, which are more about monetization than education, is a step backward. The lack of useful tutorials and fundamental mechanics guidance means new players will likely have to seek outside resources to understand the game’s deeper systems.
Conclusion
College Football 25 offers a solid foundation with its engaging on-field action and impressive visuals. However, the game’s shortcomings in UI design, mode depth, and tutorial support prevent it from reaching its full potential. If you’re a fan of college football looking for a visually stunning and dynamically engaging game, you’ll find a lot to enjoy. However, if you’re expecting a well-rounded experience with robust modes and user-friendly design, you might be disappointed.
As the game matures and future updates are released, there’s hope that some of these issues will be addressed. For now, cheap NCAA Football 25 Coins stands as a game with great potential but also significant room for improvement.
