1.什么是酶？ 酶是具有催化作用的蛋白质，同时酶具有活化性，但酶不是微生物也不是细菌，没有生命。
​2.酶来自哪里？ 酶来自自然界的各种生物，但商品化的酶是经过微生物发酵而来。

提高整件牛仔附加值的手法，已经越来越集中在手工工艺方面了。整条裤子的价值高低大部分取决于裤子是否美观是否令人有舒服，自然的感觉，再不是以前的那种硬邦邦的东西了。洗水手工工艺分为好多种，靠的是水洗师精湛的技艺和丰富的经验，可不只是个体力活儿！今天，来瞧一瞧最常用的几种手工工艺吧。

During the weaving process, fibers need to be sized to increase their fastness. When dyeing, bleaching, and printing the fabric, the paste needs to be removed, and after printing, the paste also needs to be removed. The quality of desizing directly affects the quality of the finished product, such as hand feel, whiteness, smoothness, color dosage, white core, and strength. Most of them use starch slurry for sizing, and there are many methods for desizing, such as caustic soda, sulfuric acid, hydrogen peroxide, etc. However, these chemical products not only damage the fabric and are difficult to operate, but also pollute the environment.

我们为什么要在固色剂加入洗涤剂呢？其中有什么奥妙吗？
​ 一、固色剂加入涂料，是促进涂料干燥。有时为了一副好看的画画的作品，还真不得不得不想一些奇奇怪怪的方法，而这也是根据科学依据来评判的。此系列涂料称为双组份涂料，因为为了快速干，有些画家不得不加入固色剂，加速它的速度。在建筑中也起到非常不错的作用呢？（施工中加入固色剂，不加固色剂的称为单组份），不加入固色剂的话，涂料实干不了。

What is an anti dye? Generally speaking, anti dyeing agents refer to substances that can prevent the formation of patterns due to dye coloring on fiber fabrics or during the printing and dyeing process. From the analysis of physical and chemical properties, anti dyeing agents specifically refer to anionic surfactant complexes formed by chemical modification of various non ionic surfactants and buffering agents. Has good dispersion and solubilization capabilities.

染色中色光怎么控制？
​ 一、产生色光偏差的原因
​1、不同批次的前处理半成品布，由于其纤维性能白度、毛效程度等存在差异，而引起染色布色光偏差。
