Improvements in or relating to bleaching textile materials

Textile materials not containing wool are bleached with an aqueous solution of permonosulphuric acid or a salt thereof at a temperature up to 80 DEG C. The pH of the solution may be above 7 for natural cellulosic fibres, e.g. cotton or jute, but below 7 for cellulose acetate fibres, nylon or perlon.

Multi-component encapsulated reactive formulations

The present invention provides a multi-component encapsulated reactive formulation comprising a mixture of two or more dry powder components, where each dry powder component is formed from a phase inversion process involving vigorous mixing. The dry powder is stabilized by hydrophobic colloidal particles, which assist in generating stable "dry water" microdroplets. One dry powder component comprises hydrophobic colloidal particles encapsulating microdroplets comprising an aqueous solution of one reactant, and the at least one other dry powder component comprises hydrophobic colloidal particles encapsulating microdroplets comprising an aqueous solution of another reactant. When the encapsulated formulation is agitated such that the encapsulates are broken, the encapsulates rupture and the two aqueous solutions undergo a reaction upon contact.

Process for the treatment and the coloration/dye of hides, proteicheproteiche fibers, and the wool in the combed or rebuked fiber form.

Oggigiorno il trattamento e la tintura dei prodotti tessili prevede come da tempo immemore l’applicazione di composti organici ed inorganici sul supporto tessile attraverso l’ausilio dell’acqua come solvente. L’acqua è quindi il solvente principale e di uso comune nel trattamento dei tessili in generale. In acqua vengono disciolti sostanze per la preparazione dei substrati alla tintura dei tessili e della pelle, materie coloranti e composti ausiliari per la tintura o stampa, per finire all’applicazione di resine o altre sostanze atte al cambiamento morfologico del substrato nella fase del finissaggio degli stessi. Negli anni sono stati fatti tentativi di sostituzione dell’acqua vista come bene primario per l’umanità di cui ne conosciamo l’importanza come risorsa sempre più scarsa a causa del continuo incremento di utilizzo da parte dell’uomo e dell’industria.

Patent IN155377B

Cotton fabric enzyme oxygen, which moves back, boils drift short-flow pre-treating process

本发明涉及一种棉织物酶氧退煮漂短流程前处理工艺，包括如下步骤：配置酶氧退煮漂整理液；烧毛后的棉织物在酶氧退煮漂整理液中两浸两轧，轧液率80％‑90％；汽蒸，100℃、45分钟；水洗，95℃、2格，85℃、3格，冷水、2格；烘干；所述的酶氧退煮漂整理液由果胶酶1.5‑3Kg、纤维素酶0.5‑1Kg、螯合分散剂5‑7Kg、双氧水4‑6Kg、双氧水稳定剂1.5‑2Kg、渗透剂1‑2Kg、自来水500Kg配制成。短流程前处理，节水、节电、节约蒸汽、节省时间；减少烧碱、双氧水用量；工艺简单，方便操作。

Process for bleaching textiles made from artificial fibers

Bleaching and shive reduction process for non-wood fibers

本发明涉及煮练和提高非木材纤维亮度的方法。该方法包括：形成非木材纤维的混合物，将该混合物暴露于煮练液和包含氧气的煮练剂以形成煮练混合物，以及通过使煮练液径向循环经过整个煮练混合物来煮练该煮练混合物，以提供经煮练的纤维。

Cotton fabric bleaching method using polyoxometallate

本发明属于纺织技术领域，公开了一种多金属氧酸盐漂白棉织物的方法。本发明先将棉织物用乙醚和pH为5～6的含螯合剂的酸性溶液清洗，去除棉织物表面表面的油脂和蜡质以及附带的金属离子；然后在30～70℃温度条件下以浴比1:(5～30)浸泡在pH为6～12的含有多金属氧酸盐、过氧化氢、精炼剂和渗透剂的漂液中10～40min，再加入硅酸钠继续处理10～30min，后取出洗涤并烘干。本发明提供的漂白棉织物避免了现有技术中高温高碱条件下进行漂白时过氧化氢会产生分解，进而导致生产成本提高和对棉织物造成氧化损伤的问题，所需时间短、对环境污染小。

Oxygene bleaching

The invention relates to a method for the chlorine-free bleaching of celluloses having an alpha -cellulose content of more than 90%, preferably of bucked or kiered cotton linters, in which more than a 75% degree of whiteness is achieved by means of oxygen in a one-step process, characterised in that bleaching is carried out with oxygen which has been obtained by disproportionation of peroxo compounds in the pH range 6-13 and the bleaching time is between 15 and 150 min, depending on the bleaching temperature of 35 DEG C to 15 DEG C.

Bleaching and shive reduction process for non-wood fibers

The present invention is directed to a method of increasing the brightness of non-wood fibers. The method comprises forming a mixture of non-wood fibers and exposing the mixture to a brightening agent, the brightening agent being a permanganate compound, an acid, or a combination of the permanganate compound and the acid. The resulting brightened fibers have a brightness greater than the fibers of the mixture before exposure as measured by MacBeth UV-C standard.
