Embodiment 1

[0056] Dissolve PMA, CA, and SHP with a molecular weight of 600 in distilled water at a weight ratio of 2:5:3 at room temperature to obtain a crosslinking agent solution. The content of PMA in the crosslinking agent solution is 40g / L, and the content of CA is 100g / L, the content of SHP is 60g / L. Immerse the cellulose fibers in the above crosslinking agent solution, soak for 10 minutes to obtain mixed fibers, preheat the mixed fibers, and control the preheating temperature at 70, 80, and 90°C respectively, and then heat the mixed fibers at 170°C for 8 minutes. Wash and dry. The wet friction values ​​and mechanical properties of the obtained fibers are listed in Table 1.

Abstract

The invention discloses a cross-linking agent composition, an antigen fibrillating solution spinning cellulose fiber, and preparation methods thereof. The cross-linking agent composition comprises low poly polybasic acid of which the molecular weight is 400-1000, and C2-C6 polyatomic acid; the weight ratio of the low poly polybasic acid to the C2-C6 polyatomic acid is 1:(1-5). The multi-anhydride containing an anhydride bond is easily formed between the low poly polybasic acid and a carboxyl functional group (-COOH) in polybasic acid in a high-temperature heating process of crosslinking reaction. Thus, reaction with hydroxyl of the cellulose is easily carried out, and more crosslinking structures are formed. The crosslinking agent composition has a prominent role in improvement of the antigen fibrillating performance of the fiber.

Description

technical field [0001] The invention relates to the field of fiber processing, in particular to a crosslinking agent composition, an anti-fibrillation solution-spun cellulose fiber and a preparation method thereof. Background technique [0002] The cellulose is dissolved in an appropriate solvent to form a cellulose solution, and then the solution is extruded into a spinning coagulation bath, where the cellulose is coagulated and regenerated, and then stretched to form fibers. The above method is called "solution spinning", and the resulting fibers are solution spun cellulose fibers. The representative of the known solution-spun cellulose fiber is viscose fiber, but the huge environmental pollution and energy consumption problems hinder its further expansion of production scale. [0003] In order to solve this problem, both U.S. Patent US4246221 and Chinese Patent CN94190487.3 have proposed a method of using a new solvent to prepare cellulose fibers, that is, dissolving cel...
