It included enzyme unhairing,sodium hydroxide based fibre opening and pickle and basification-free chrome tanning process.

介绍了一种三步铬鞣山羊面革的加工方法，即：酶脱毛，NaOH打开皮纤维和无浸酸、无提碱铬鞣。

The chrome reduced tannage with resin tanning agent and modified glutaraldehyde pretanning, and combination Al-Cr tanning were investigated.

研究了树脂鞣剂、改性戊二醛鞣剂预鞣，铝－铬结合少铬鞣制轻革的工艺及方法。

The results of research on the factors affecting titanium tannage show that high concentration NaCl medium has larger negative effect on titanium tannage. When the NaCl concentration exceeds 5%, the titanium tanning action is reduced rapiddly. Traditional NaCl pickling is unsuitable for titanium tannage, tanning in water medium directly, the best tanning effect can be obtained, so titanium tanning can not only eliminate chrome pollution, but also diminish salt pollution. The optimum tanning conditions for HPZ-Ti tan liquor are pH3. 5, TiO〓 offer of 7. 5%(based on the weight of 65% moisture pelt), the best Bascity of tan liquor is between 30% and 50%.

以HPZ—Ti鞣液为基础，研究了不同鞣制介质，鞣制pH值，鞣剂用量和浓度，鞣液的碱度，不同提碱剂，不同的预处理和后处理等因素对钛鞣的影响，结果表明：高浓度的NaCl溶液介质对钛鞣有很大的负面作用，当介质NaCl浓度超过5%，革内钛的结合量和革的Ts明显降低，传统的高浓度NaCl浸酸工艺不适合于钛鞣，在水介质中直接鞣制效果最好，所以钛鞣不仅消除了铬污染而且大大降低了盐的污染。

The experiments are as follows: Many times degreasing,short ratio of liquor,unhairing and liming with so- dium sulfide,reliming,bating with mixture enzymes in low temperature,retan- ning with modified glutaraldehyde—chrome,many times fatliquoring partly,and so on.

陕西猪皮质量常比我国南方猪皮质量差，为了提高它的使用价值，我们做了大量的试验与观察，找出了合理地制造服装革的方法，如多工序分次脱脂，少浴硫化钠脱毛浸灰，复灰，混合酶低温软化，改性戊二醛-铬结合复鞣，多工序分次加油等，生产出&薄、轻、软&的服装革。

The result showed that some of properties of the leather made by this new technique are better than the ones made by normal process. The new technique without pickling not only leave pickling and basifying out of consideration, but also reduce chrome and clears up the pollution of salt brought from pickling to the environment.

结果表明，与常规浸酸铬鞣法相比，采用C-2000铬鞣剂及相应工艺鞣制的蓝湿革与成革的某些性能得到了提高，可以省去浸酸工序，简化工艺操作，减少酸和盐的污染，降低生产成本。

Comparing 10 kinds of fat liquors, the penetrability of fat liquoring agents in the chrome-free pigskin garment leather, and the physical-mechanical properties of fatliguored chrome-free leather were studied.

对比研究了磺化油加脂剂STO、SEO、SHO、KS-1和6种常用加脂剂在无铬鞣猪皮服装革中的渗透情况及其加脂后坯革的物理-机械性能。

Compared with 6kinds of single component in fat liquors,the penetribility of 4 kinds of sulfonated fat liquoring agents STO,SEO,SHO,SS-1 in the chrome-tanned leather,and the physical-mechanical properties of chrome-tanned leather after fat liquoringwere studied.

以6种常用加脂剂单一组分为参比，研究了四种磺化油加脂剂STO、SEO、SHO、SS-1在铬鞣革中的渗透情况及其加脂后坯革的物理-机械性能。

Chrome-tanned and finished leather clicking waste represents several hundreds thousand tons per year annually world-wide.

铬鞣革和涂饰革在世界范围内每年带来成千上万吨的废弃物。

Through orthogonal test, chrome-free tanning technology of goatskin shoe upper leather with chrome-free tanning agents such as modified glutaraldehyde,modified vegetable tannin and syntans was studied.

采用改性戊二醛、改性栲胶、合成鞣剂等无铬鞣剂，通过正交试验，优化出了多种鞣剂结合鞣制山羊鞋面革的无铬鞣制工艺。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。
