For exploiting the advanced functional fiber and new cellulose-based materials,a new cotton fiber modified with collagen protein was prepared through limited selective oxidation of cotton thread by sodium periodate,followed by reacting with the solution of collagen protein.Through analyzing the micro-morphology and the aggregation structure of cotton fiber treated with collagen protein,the changes in the micro-structure of cotton fiber coated with collagen were studied.The analysis suggested that the imine structure bonds were formed between collagen molecule and oxidized cotton fiber,and the treated fiber exhibited little change in crystallinity and marked enhancement in thermal stability.

Nitrogen adsorption is more effective than transmission electron microscope(TEM) in the study of pore structure of cotton fiber.It can be applied to a lot of samples,and more information of pore structure parameters can be acquired.By use of nitrogen adsorption isotherm and of density function theory(DFT) analysis,the pore structures of cotton fiber,such as micropore volume and pore size distributions,were characterized.The results show that cotton fiber contains open pores,the maximum value of pore size distribution appears at 2.2 nm.The pore volume with diameter ranging from 2.0 to 4.0 nm makes up 68.16% of the total,and larger than 5.0 nm,18.49%.

Film morphology and molecular orientation of N-β-aminoethyl-γ-aminopropyl polysiloxane(ASO-1) on cotton fiber were investigated by field emission scanning electronic microscope(FE-SEM) and X-ray photoelectron microscope(XPS).The experiment results indicated that the ASO-1 formed a uniform,some smooth film on the treated cotton fiber surface,especially as the working distance(WD) of FE-SEM is more than 200 nm.The XPS analysis showed that most of the N atoms from amino functional polysiloxane were fixed onto the interface between the cotton fiber and ASO-1.All of these suggests that the molecular orientation of ASO-1 on natural cotton fiber substrate is in such a manner that the silicon methyl groups project outward into air,while Si—O dipole bonds as well as amino groups point to the fiber interface.

The cellulose pulp was pre-treated with electron beam irradiation technology.The infrared(IR) spectra testing,the surface and void analysis and the wide angle X-ray diffraction(WAXD) experimentation of the cellulose pulp before and after the treatment were carried out by using FT-IR spectrum,scanning electronic microscope and X-ray diffraction apparatus respectively,and the degrees of polymerization of the cellulose pulp before and after election beam irradiation treatment were measured by the method of copper ammonia solution.The results show that electron beam irradiation results in the degree of polymerization of cellulose decreasing,molecular weight distribution narrowing and appearance of carbonyl in molecular chain of the cellulose.Electron beam irradiation has insignificant influence on crystallinity,whereas the accessibility and the reaction activity of cellulose increase greatly after the treatment.

Fibroin/polyamide blend fibers were electrospun with the mixture of 9% fibroin and 12% polyamide 6/66 copolymer formic acid solutions at 15 kV voltage and 15 cm distance from the tip of capillary to collecting screen(C-SD).The effects of polyamide content on the diameter and crystal of fiber and the mechanical properties of fiber mat were investigated.After being treated by ethanol,the morphology and performance of electrospun fibroin/polyamide fibers were analyzed.The results indicated that addition of polyamide in the fibroin formic acid solution not only decreased the diameter of fiber,but also improved its crystal and breaking strength of fiber mat.Electrospun fibroin/polyamide fibers treated by ethanol exhibited even swelling and higher crystallinity than as-spun ones,and the fiber mat was stronger and more stable in water.

The stress relaxation properties of yarns are studied.Based on the superposition principle of Boltzman,the elongation-stress relaxation process of yarns is analyzed using the standard linear solid model.Theoretical equations of the elongation-stress relaxation process are deduced.The elongation-stress relaxation experiments of polyester/rayon and regenerated bamboo fiber/cotton blended yarns are performed under such conditions as constant stress and different elongation rates and constant elongation rate and different stresses.The regressive equations of stress relaxation and correlation coefficients of the yarns are calculated.Theoretical expectations display very good agreement with the experiment observations.It indicates that the standard linear solid model can be used to describe the stress relaxation properties of yarns under lower strain conditions.It is found from the experimental and theoretical results that the higher the strain or the elongation rate,the lower the relaxation time and more apparent the relaxation phenomenon.

In order to enhance the sizing behavior of starch,a series of cynaoethyl starch with different degree of substitution were prepared by using acrylonitrile as etherifying agent and varying the feed ratio of acrylonitrile to cornstarch for changing the degree of substitution of the starch ether.The influences of the modification method and extent on the behavior of starch film and adhesion to fibers were studied.The experimental results demonstrate that the starch etherification can improve the breaking strength,breaking elongation,flex resistance and wear loss of starch film.As the degree of substitution increases,the adhesion of cynaoethyl starch to cotton fibers initially increases and then decreases.A maximal bonding strength can be achieved when the degree of substitution is 0.047.However,the adhesion of the modified starch to polyester and polyester/ cotton fibers decreases as the degree of substitution increases when the degree of substitution exceeds 0.017.

Two kinds of anti-setting agents synthesized in the laboratory were used in cashmere fibers simulation dyeing process under different conditions.Their protective effects were evaluated in terms of length,diameter,elongation at break and breaking strength of both the treated and untreated fibers.Experiment results show that the two kinds of anti-setting agents have remarkable protective effect for cashmere fibers during dyeing process.The fibers dyed in presence of anti-setting agents were superior to those dyed in absence of the agents in terms of all properties.The hydrophobic agent with high active functional group is better than the one with low active group.The longer the dyeing time,the shorter the fiber length,the coarser diameter,and the worse the tensile properties.When the anti-setting agents used in the range of 3% ~8%(o.w.f) during dyeing,it is beneficial to reducing the damage of cashmere fibers with increase of dosage.
