Description

[根据细则37.2由ISA制定的发明名称]　天然印花增稠剂[Name of invention established by ISA in accordance with Rule 37.2] Natural printing thickener 技术领域Technical field
本发明属于染色助剂应用领域，具体涉及一种天然印花增稠剂。The invention belongs to the field of dyeing auxiliary applications, and in particular relates to a natural printing thickener.
背景技术Background technique
天然多糖增稠剂由天然多糖及其然生物构成，历史悠久，品种众多，几乎适用于所有染料的印花工艺，具有低环境污染的优点。但是与合成增稠剂相比，其印花糊具有不耐剪切性和年度易于下降的确定，并且当用于涂料印花时还存在用量大和在织物表面残留量高的问题，影响了印花织物的手感和色牢度。多糖增稠剂适用于大多数类别的染料印花，但大多不适合活性染料印花。这是因为分子中大量的羟基会与活性染料反应，造成印花织物手感差及染料利用率低的问题。另外，还有些增稠剂的黏着力不够且韧性不足，使得烘干后糊料薄膜硬脆易脱落。这些问题均在一定程度上影响了印花效果。The natural polysaccharide thickener is composed of natural polysaccharides and its natural organisms. It has a long history and many varieties. It is suitable for printing processes of all dyes and has the advantages of low environmental pollution. However, compared with synthetic thickeners, the printing paste has the characteristics of not being resistant to shearing and easy to fall in the year, and when used for paint printing, there is also a problem of large amount and high residual amount on the surface of the fabric, which affects the printed fabric. Feel and color fastness. Polysaccharide thickeners are suitable for most types of dye printing, but most are not suitable for reactive dye printing. This is because a large amount of hydroxyl groups in the molecule react with the reactive dye, resulting in a problem of poor hand touch and low dye utilization. In addition, some thickeners have insufficient adhesion and insufficient toughness, so that the paste film is hard and brittle after drying. These problems have affected the printing effect to some extent.
印花色浆一般是由增稠剂、染料和各种印花助剂(缓冲剂、吸湿剂、表面活性剂、分散剂等)物理共混而成的有色黏稠体系。该体系中，既有高分子的增稠剂，又有小分子的染料；既有带不同电荷的表面活性剂，又有pH值不同的缓冲剂，组分间的相互作用不可避免。不仅如此，色浆与纤维间也存在各种相互作用，如氢键、范德华力、共价键等。这些作用力在印花的各阶段均有体现。例如:在印花前，色浆要具备一定的化学稳定性，放置数日不可分层或絮凝；在印花过程中，染料与色浆中其他组分的亲和力要小，才有利于染料从色浆中释放，获得高的上染率；在印花结束后，增稠剂与纤维间的亲和力要小，才有利于色浆的洗脱，获得手感柔软的印花织物。Printing paste is generally a colored viscous system which is physically blended with thickeners, dyes and various printing auxiliaries (buffering agents, hygroscopic agents, surfactants, dispersants, etc.). In this system, there are both thickeners of polymers and dyes of small molecules; there are surfactants with different charges and buffers with different pH values, and the interaction between components is inevitable. Not only that, but there are also various interactions between the color paste and the fibers, such as hydrogen bonds, van der Waals forces, covalent bonds, and the like. These forces are reflected in all stages of the print. For example, before printing, the color paste should have certain chemical stability, and it should not be layered or flocculated for several days. In the printing process, the affinity of the dye and other components in the colorant is small, which is beneficial to the dye from the color paste. In the middle release, a high dye uptake rate is obtained; after the printing is finished, the affinity between the thickener and the fiber is small, which is beneficial to the elution of the color paste, and a soft printed fabric is obtained.
淀粉及其衍生物，包括玉米淀粉、糊精及印染胶他们在印花后淀粉糊难以从织物表面清除，造成隐花植物手感硬挺性和色泽不均匀的问题；植物性胶，包括海藻酸钠、醚化植物胶及树胶，海藻酸钠作为糊料印花时给色量高渗透性良好，印制精细花纹时候轮廓清晰，印花得色均匀，但是海藻酸钠遇水易与水中的金属离子产生络合现象而发生沉淀，降低染色牢度。Starch and its derivatives, including corn starch, dextrin and printing and dyeing glue, they are difficult to remove from the surface of the fabric after printing, resulting in the problem of the firmness and uneven color of the cryptic plant; the vegetable gum, including sodium alginate, Etherified vegetable gum and gum, sodium alginate as a paste printing, the color yield is high and the permeability is good. When the fine pattern is printed, the outline is clear and the printing color is uniform, but the sodium alginate is easy to form with the metal ions in the water. Precipitation occurs when the phenomenon is combined, and the color fastness is lowered.
