The Research Of Rabbit Hair Fiber’s Performance Optimization By Plasma And Nano Cellulose

Rabbit hair (RH) is a huge important kind of animal protein fiber, but it’s so hard to produce and easily gets itself dropped in the process of wearing and washing that rabbit hair gets great hinder in the clothing function. This paper uses several methods to change rabbit hair fiber (RHF)’s performance such as plasma treatment(PT)、 nano-cellulose modification(NCCM)、 low temperature plasma/nano-cellulose fibers modification,etc, aiming to improve RHF’s processing and wearing ability, widening its application district and value.The PT experiment machine developed by Shanghai Textile Research Institute is applied to optimize the performance of RHF, it changes the friction’s coefficient of cis-scale and inverse-scale and increase its processing ability and pre-hair loss ability.As the experiment confirms, PT makes micro pit and bump in the surface of RHF, improves RHF’s friction coefficient, however, influencing little on tensile properties. The friction the coefficient reaches the its maximum after3minutes in the PT when the static coefficient of friction gets improved by59.25%and22.91%than the original rabbit fibers, in the same moment, in the same moment, the cis-scale friction’s coefficient is narrowing, which helps to reduce RHF’s shaking resistance. However single PT causes the RHF feel dry,rough, like the dry hair lack of water.Microcrystalline cellulose was prepared for nano-cellulose fiber in this paper and was applied to RHF modification. We can see that apparently the nano-cellulose fiber attached on the surface of RHF and scattered mainly near the tip and the motch of scales, improves RHF’s friction coefficient in some extent. RHF’s forward friction coefficient reached its maximum, improved27.34%compared with the original RHF, but the inverse friction coefficient only increased5.53%. Due to the experiment, the RHF’s friction coefficient after NCCM goes smaller than PT RHF, but the nano-modified cellulose fibers maintained soft, smooth waxy feel of the rabbit hair. PT/NCCM united with joint RHF combined with the advantage of PT and NCCM, not only enhanced RHF’s friction coefficient, but also contains RHF’s mechanical performance, as well has soft and slippy feel.Through orthogonal experiment, we came to the final plan A1B1C2, which is0.5%mass fraction of nano-cellulose,30minutes of soaking time,3minutes of PT. Optimal process verified again, static forward friction coefficients were0.2208,0.2483, improved32.7%,11%than the original RHF, breaking strength loss rate was merely1.21%, fracture elongation was37.8%.
