| titleOfInvention | Technique for producing dissolving pulp from whole cotton stalks |
| abstract | The invention relates to the technical filed of a dissolving pulp, in particular to a technique for producing a dissolving pulp from whole cotton stalks. The technique comprises the steps of adding a hydrolysis accessory ingredient a into cotton stalks; performing pre-hydrolysis at a certain temperature for a certain time; carrying out KP/AQ cooking for the hydrolyzed pulp; performing OHP bleaching on the cooked pulp in three stages; and adding a hydrolysis accessory ingredient b into the bleached pulp for post-hydrolysis to obtain the dissolving pulp. According to the technique for producing the dissolving pulp from whole cotton stalks, hemi-cellulose is greatly dissolved out from the cotton stalks with the help of the pre-hydrolysis of the added accessory ingredient firstly; finally the content of the hemi-cellulose in the cotton stalks is further reduced by the post-hydrolysis of the added accessory ingredient; the processes of KP/AQ cooking and OHP bleaching are combined to prepare the cotton stalk dissolving pulp which is high in alpha-cellulose content, low in pentosan content, low in hemi-cellulose content and high in reactivity; and the adopted chemical products are clean and environment-friendly by utilization of the technique provided by the invention for processing whole cotton stalks. |
