Preparation and Application of the Hydrophilic Amino-Silicone softener by Emulsion Polymerization

Advances in Chemical Engineering and Science 2020年第1期10卷 1-23页

作者： Ruza Artikboeva Yue Wu Mingxing Yang Chen Jie Quan Heng Chemistry Department Wuhan Textile University Wuhan China

The amino poly-siloxane was modified with self-made polyether silicones by the crafts of emulsion polymerization. We studied the emulsifier, the dosage of emulsifier initiator, polyether/silane coupling agent, pH value. There are some results of the research indicated in the following. First, there are many factors for the hydrophilic amino-silicone softener both on the polymerization process and the performance, such as the proportion and amount of emulsifier, initiator dosage, the mass ratio of the polyether and hydrogen silicone oil, the choice of silicone coupling agent, and the ratio and dosage of polyether silicones silane coupling agent. Second, the amount of hydrogen of the hydrogen silicones and the choice of catalyst are the key points on the synthesis of polyether silicones. The amount of hydrogen should be low and the catalyst must be economical and efficient and its introduction should be small and times, other more the holding time is not too long. The next one is that, in the process of hydrolysis of silane coupling agent, we need some acid to adjust pH value, or they will be broken down. The most important one but not the last is that the epoxy group can improve the products low-temperature supple and the persistence of the finishing fabric, furthermore it can reduce yellowing and has a good stability of the inorganic salt, however, it will be destroyed if the reaction temperature for epoxy is too high. What’s more, it is very economical and environmental that the process of emulsion is simple and with less emulsifier.

Observation of a Chemical softener’s Effects on Stem-Specific Lignocellulosic <i>Brassica napus</i>(Type: Canola) (Cultivar: HYHEAR 3) Fiber Quality

引用

Chemical softener (Cepreton UN) is used to soften the cellulosic fiber (cotton) in the textile industries to make clothes better to touch. Therefore, this study investigated the effects of Cepreton UN on both physical (length, aspect ratio, contact angle, and moisture regain) and mechanical (load at break, elongation at break, tensile stress, young’s modulus, and tenacity) properties of the lignocellulosic canola (HYREAR 3) fibers extracted from narrow, medium, and wide stems. ANOVA showed that fiber diameter had strong effects on elongation at break, load at break, tensile stress, young’s modulus, and aspect ratio for all fibers. Corrgram values showed that tensile stress, young’s modulus, and aspect ratio were negatively correlated to fiber diameter whereas load at break and tenacity were mostly positively correlated to fiber diameter. The fibers were treated with 2% and 10% Cepreton UN and compared with control fibers. In most cases, the fiber diameter was decreased in both 2% and 10% treated medium stem fibers. The mean values of elongation at break, load at break, tenacity, and contact angle were decreased for 10% and increased for 2% and the mean values of tensile stress, young’s modulus, and aspect ratio were decreased for 2% and increased for 10% treated medium stem fibers. Moisture regain (%) mostly decreased for 2%, and increased for 10% treated fibers. Low pH (4.5) had an almost similar effect on fibers as 2% Cepreton UN. Overall, 2% Cepreton UN treatment is found to be better than 10% to make canola fibers less stiff and low pH was found to be an alternative softener treatment strategy.

The Study of Handle Improvement of Low Quality Cashmere

引用

Journal of China Textile University(English Edition) 1998年第4期15卷 51-55页

作者：朱泉吴婵娟戴瑾瑾

To improve low quality cashmere (sheep cashmere) has received special attention. This report shows how the sheep cashmere fabrics can be modified for an extremely soft handle similar to high quality cashmere to meet par-ticular market requirements. This enables the sheep cashmere fiber to be used in a much broader range of products. In order to get very soft handle products, the most effective processes are to give a chlorination pre-treatment followed by the polyurethane and the aminosil-icone treatments under suitable conditions.

关键词： cashmere handle improvement softener pre-treatment chlorination.
