Abstract
The present invention relates to a boiling and bleaching method of flax roving, which is mainly characterized in that the boiling and the bleaching of flax roving are completed once at normal pressure. The method comprises the following technological processes: water washing, acid washing, boiling, water washing, oxygen bleaching and water washing. Because no sodium chlorite is used in the process of boiling and bleaching, the method has no toxicity, no pollution and no explosion danger. In addition, the method can satisfy the condition requirements of a fine yarn spinning technology, and yarn strength is enhanced greatly. The method can satisfy the quality requirement of universal yarn on the international market. The method has the advantages of stable technological parameter and reliable technology, and the operating environment can be improved greatly.
Description
The invention belongs to flax spinning technology field, particularly belong to flax roving boiling and bleaching process field.
The existing roving boiling and bleaching of present domestic flax spinning factory adopts inferior oxygen bleaching process, purpose is that part removes pectin, lignin, removal pigment impurity etc., increase fiber division degree, help spun yarn processing, its technical process is: and pickling → Asia floats → washes → and oxygen floats → washes, sodium chlorite owing to employing in this technology belongs to strong oxidizer, very easily fire explosive, bring very big inconvenience for transportation, keeping and use, and often have the chlorine dioxide generation to cause environment abominable in the operation, it is healthy directly to endanger the operator.And the rove behind the half deguming makes finished product yarn brute force can not reach the expection requirement because sodium chlorite causes cellulose damage (being referred to as chlorine damage).Chinese patent application number is 92105486 bibliographical informations with twice hydrogen peroxide boils to float and replaces sodium chlorite of the prior art and boil to float to boil with hydrogen peroxide and float, but always not in factory application, the Western European countries adopt the dioxygen bleaching process mostly at present.
The present invention seeks to develop a kind of practical roving boiling and bleaching process that is suitable at the deficiency of above-mentioned existing roving boiling and bleaching process, the present invention not only satisfies spun yarn spinning process conditional request, and yarn strength increases substantially, can satisfy the general yarn quality requirement in international market, technological parameter is stable, technology is reliable, and improves operating environment greatly.
Technical scheme of the present invention is that the flax roving normal pressure boils and floats one-step method, and its technical process is: and washing → pickling → boil floats → and oxygen floats → washes, and detailed process is:
