Method for preparing modified starch tanning agent

The invention discloses a method for preparing a modified starch tanning agent, comprising the following steps of: firstly, degrading corn starch; in the presence of HRP (Horse Radish Peroxidase)/ hydrogen peroxide (H2O2), grafting and modifying the degraded starch with sulfanilic acid, gallic acid and nekal; and then oxidizing the grafted starch with periodic acid. The invention has the innovation points that a nekal structure unit is introduced in the starch structure so as to improve the permeation wetting function of the modified starch tanning agent; the gallic acid structure unit is introduced to improve the tanning properties of the modified starch tanning agent, the sulfanilic acid is introduced to increase the dispersivity of the modified starch tanning agent, and dialdehyde action is used for improving the tanning properties of the modified starch tanning agent. The preparation method of the invention is peculiar and practical, and the obtained tanning agent is an environmentally-friendly leather tanning agent and is suitable for primary tanning and retanning. The shrinkage temperature (Ts) of pickled leather after primary tanning can be improved to 75-80 DEG C; and the retanned product has the advantages of wash resistance, high absorption rate on dyes and fatting agents and the like, is soft and plump.

Natural down flocculus made of composite thermal insulation materials and manufacturing process of the natural down flocculus

The invention relates to a natural down flocculus made of composite thermal insulation materials, which is made through taking down mainly comprising duck down and goose down as a main material, as well as a manufacturing process of the natural down flocculus. The natural down flocculus made of the composite thermal insulation materials is made of blend fiber and down mainly comprising duck down and goose down, wherein the blend fiber is formed by blending meldable fibers and polyester staple fibers according to weight ratio of (13-18):(6-15); and the blended ratio of the down and the blend fiber is determined according to the requirement of a down product. In manufacturing, animal down serves as a main material while the meldable fibers and the polyester staple fibers serve as auxiliary materials; and the composite thermal insulation material with the down content of above 65% is produced according to different ratios of all materials. The down flocculus has a good thermal insulation property like a down product or a cashmere product, is green and environment-friendly, and also has spinnability and tailorability. The process is relatively low in cost, concise and mature in process and easy to operate, and has a great market potential.
