The invention relates to a method for preparation of a colored special-shaped elastic multifilament fiber by polyether ester/PTT (polytrimethylene terephthalate) composite spinning. The colored special-shaped elastic multifilament fiber is prepared by subjecting 80-95% of PTT, 5-20% of polyether ester, 2-5% of an interface modified amphiphilic polymer, 5-10% of masterbatches, and 0.5-1% of an antioxidant to blending, melt extrusion and stretching. The filament number is 1-5detx, the multifilament breaking strength 1-5cN/dtex, and the elongation at break is 10-40%. The preparation of the multifilament fiber provided by the invention can be finished on conventional spinning equipment, tow tops are dry and even, and after weaving, the color distribution is uniform. The colored special-shaped elastic multifilament fiber provided by the invention can be widely used in the clothing field and the decoration field, and the obtained fabric has soft handfeel and very good elastic resilience.

The invention relates to a single-component anti-bacteria anti-yellowing colored silicone sealant for a fish tank and a preparation method of the single-component anti-bacteria anti-yellowing colored silicone sealant. The sealant is composed of, by weight, 100 parts of dihydroxy polydimethyl siloxane, 5-10 parts of quaternary ammonium salt end group modified dimethyl polysiloxane, 0-10 parts of pigments, 8-15 parts of fillers, 5-10 parts of acyloxy silane crosslinking agent, 1 part of coupling agent and 0.1 part of catalyst. By adding the bright-colored pigments, the attractiveness and practicability of the product are improved, and the product is easier to meet the demands of the market. By selection and matching of the viscosity of the 107 adhesive and addition of the coupling agent, a system is further reinforced, the elongation is controlled within a reasonable range, and the adverse effect on the sealant properties due to addition of the pigments is avoided. The method that an original silicone sealant adopts common dimethicone is changed to the method which adopts quaternary ammonium salt end group modified dimethyl polysiloxane so that the silicone sealant for the fish tank can keep colored for a long time, moreover, mildewing and bacteria breeding are not prone to occurring, the sealant is environmentally friendly, and the fish tank can keep clean and attractive for a long time.

The invention provides a method for dying wool by using natural raw materials, and applications of produced wool. The method comprises the following steps: twisting non-shrinkable wool into woolen yarn with thickness of 2-5mm, then winding the woolen yarn into a coil with the circumference of 20-30cm, bundling the coil into coils with diameters of 30-50cm before dyeing; grinding and adding colored matter-containing natural raw materials into boiling water, and evenly stirring to obtain a dye system, wherein the natural raw materials are selected from mineral raw materials and plant raw materials; adding the non-shrinkable wool into the dye system, then adding dyeing auxiliaries, dyeing for 3-12 hours under boiling status; placing the dyed wool into room-temperature water and soaking and continuously washing to remove flooding and impurities; and drying at 30DEG C below and blowing cold wire.
