Method for preparing functional composite woolly elastic fiber

The invention relates to a method for preparing functional composite woolly elastic fiber, comprising the following steps: (1) preparing uvioresistant fine-denier polyester pre-oriented yarn (a) with the method of adding uvioresistant masterbatch; (2) carrying out composite spinning with low viscosity polyester (PET) or modified PET and polyethylene terephthalate (PTT) to prepare fully-drawn self-winding composite elastic fiber (b); and (3) stretching and false twisting the uvioresistant fine-denier polyester pre-oriented yarn (a) on a false-twisting texturing machine, converging the uvioresistant fine-denier polyester pre-oriented yarn (a) and the fully-drawn self-winding composite elastic fiber (b) in the position of a second roller, combining the uvioresistant the fine-denier polyesterpre-oriented yarn (a) and the fully-drawn self-winding composite elastic fiber (b) through an interlacing machine, shaping the uvioresistant the fine-denier polyester pre-oriented yarn (a) and the fully-drawn self-winding composite elastic fiber (b) through a second heating box, and winding the uvioresistant the fine-denier polyester pre-oriented yarn (a) and the fully-drawn self-winding composite elastic fiber (b) into a composite yarn, contracting the PET / PTT self-winding composite elastic fiber with the elasticity and the contractibility in the core layer of the composite woolly elastic fiber to show the elasticity of the composite yarn, and making the uvioresistant fine-denier polyester pre-oriented yarn to float on the surface layer of the composite yarn to show the uvioresistant performance of the composite yarn. Therefore, the uvioresistant composite woolly elastic fiber is prepared.

Preparation technology of far-infrared cotton fiber

The invention discloses a preparation technology of far-infrared cotton fiber. The preparation technology comprises the steps of preparing raw materials, treating the raw materials, preparing a far-infrared mixed solution, carrying out coating treatment and spinning. The preparation technology is simple in method; the far-infrared coating mixed solution is prepared by mixing far-infrared ceramic powder with a resin bonding agent, a cross-linking agent, a dispersing agent and the like; the treated raw material fiber is coated with the far-infrared coating mixed solution, and the far-infrared coating mixed solution is firmly combined with the raw material fiber, so that the far-infrared fiber is good in effect. An ultraviolet light absorber is also added to the far-infrared coating mixed solution and is dipped into the cotton fiber, so that the finished product fiber has an ultraviolet resistant function. The cotton fiber is refined by alkaline biological enzyme, and alkali treatment is replaced, so that the preparation technology is low in damage to fiber and is beneficial to maintaining fiber strength; apocynum venetum fiber and activated carbon fiber are added into the raw material fiber for use, so that the finished product fiber also has a good antibacterial effect.

Anti-ultraviolet unidirectional-moisture-permeable fiber composite and preparing method thereof

The invention belongs to the field of functional micro-nano fiber composites, and particularly relates to an anti-ultravoilet unidirectional-moisture-permeable fiber composite and a preparing method thereof. The fiber composite comprises a polypropylene layer and a hydrophilic polymer and ultraviolet absorber mixture layer which are integrally combined. Polydopamine deposits on and adheres to thesurfaces and the interiors of the polypropylene layer and the hydrophilic polymer and ultraviolet absorber mixture layer. The preparing method includes the steps of dissolving an ultraviolet absorberand a hydrophilic polymer in an organic solvent to form a spinning solution, conducting static spinning and then hot-pressing treatment with a melt static spinning polypropylene fiber material as thereceiving substrate, and placing the material in a Tris-HCl buffer solution with dissolved dopamine for impregnation modification to prepare the anti-ultravoilet unidirectional-moisture-permeable fiber composite. The material has good unidirectional moisture-permeable and anti-ultraviolet functions and is stable in integration structure, simple in composition and structure, simple in preparing process and wide in application prospect.
