Embodiment 1

[0041] Immerse the fiber in the prepared cross-linking solution, the concentration of butanol-etherified melamine in the cross-linking solution is 8%, the concentration of dinonyl naphthalene disulfonic acid catalyst is 1%, two dipping and two rolling, and the pass ratio is controlled at 120% After curing for 30 minutes at a certain curing temperature, washing with water three times, and drying at 85°C, the lyocell fiber with anti-fibrillation ability was obtained. The obtained fiber was measured for wet wear value, and the blank sample was the fiber without cross-linking treatment. The results are shown in Table 1.

Embodiment 2

[0046] Immerse the fiber in a cross-linking solution with a certain concentration of butanol-etherified melamine, with a methanesulfonic acid catalyst concentration of 1%, three dips and three rollings, and the scrapping rate is controlled at about 140%, cured at 120°C for 5 minutes, and washed four times , and dried at 95°C to obtain lyocell fibers with anti-fibrillation ability. The obtained fiber is measured for wet wear value, and the blank sample is the fiber without cross-linking treatment, the results are shown in Table 2:

[0049]

[0050] With the increase of the concentration of butanol-etherified melamine, the wet wear value gradually increased. When the concentration of butanol-etherified melamine reached 6wt%, the wet wear value reached 802.92. Compared with the blank sample, the wet wear value increased by 1330.47%. Far exceeds the wet abrasion value...

Embodiment 3

[0052] The fibers are immersed in the prepared cross-linking solution, the concentration of butanol-etherified melamine in the cross-linking solution is 4%, the concentration of HMMM is 4%, and the concentration of the mixed catalyst of p-toluenesulfonic acid and dodecylbenzenesulfonic acid is 1 %, two dipping and two rolling, the excess rate is controlled at about 160%, curing at 150°C for a certain period of time, washing twice, and drying at 85°C to obtain lyocell fibers with anti-fibrillation ability. The obtained fiber is measured for the wet abrasion value, and the blank sample is a fiber without cross-linking treatment, and the results are shown in Table 3:

Abstract

The invention provides an antigen fibrillation cross-linking agent for lyocell fibers. The antigen fibrillation cross-linking agent comprises a cross-linking agent active material as shown in a formula (I) and a strong acid catalyst. The invention further provides the lyocell fiber. The invention further provides a treatment method for fibrillation of the lyocell fiber antigen. According to the invention, the specific antigen fibrillation cross-linking agent is adopted to treat the lyocell fibers, such that the lyocell fibers can have strong antigen fibrillation ability so as to create the space for providing the diversified lyocell fibers.

Description

technical field [0001] The invention relates to the technical field of lyocell fibers, in particular to an anti-fibrillation crosslinking agent for lyocell fibers and an anti-fibrillation treatment method for lyocell fibers. Background technique [0002] Lyocell fiber is known as the green fiber of the 21st century. It is a regenerated cellulose fiber used in wet spinning with N-methylmorpholine-N-oxide as a solvent; its main composition is the same as that of cotton or viscose The same is cellulose, its molecular weight and crystallinity are between cotton and viscose. [0003] Lyocell fiber products will produce obvious fibrillation phenomenon under the action of mechanical external force friction in wet state. This phenomenon is manifested by the separation of finer fibrils in the longitudinal direction of the fibers and hairiness on the surface of the yarn. Easy fibrillation is one of the characteristics of ordinary Lyocell fibers. Fibrillation refers to the splitting o...
