The present invention relates to a breast cancer early warning chip for measuring I type theymine deoxyriboside kinase gene protein (hTK1) easily and rapidly. The invention is characterized in that the breast cancer early warning chip is composed of the following components: a strip fiber chromatography solid phase carrier NC film which is encapsulated with an anti-hTK1 monoclone antibody (numberfor 2A6-McAb) that is expressed and prepared by eukaryon at one end and is encapsulated with rabbit anti-mouse IgG monoclone antibody at the other end, a filtering sample paper, a water-absorbing glass fiber paper, and a polyester diaphragm which is marked with colloidal gold and secondary antibody hTK1 monoclone antibody (number for 3E8-McAb) bonder and the like components which are adhibited ona white PVC plastic piece. The invention has the characteristics and advantages of trace quantity, high speed, sensibility, accuracy, easiness, good stability, high repeatability, strong specificity,without special equipment or device, low detecting cost, measurement to single share or a plurality shares of specimen respectively, convenient carrying and convenience for site or field general investigation or physical examination.

The invention relates to the technical field of a textile finishing agent, and concretely discloses a fiber dyeing deepening agent. The textile finishing agent is prepared from the following formula raw materials in percentage by mass: 5.0.0 to 10.0 percent of emulsifiers, 10.0 to 20.0 percent of aliphatic amine, 25.0 to 35.0 percent of aliphatic amine derivatives, 3.0 percent of acid, 5.0 to 8.0 percent of aliphatic alcohol, 3.0 to 5.0 percent of urea and the balance deionized water. The fiber dyeing deepening agent has the advantages that the coloring effect on spandex (lycra) and nylon is extremely good; no allergy, no teratogenesis, no mutagenesis and no carcinogenesis are caused; no toxic and side effects are caused on the human body; the energy is saved; the environment is protected.

The invention relates to the technical field of textile printing and dyeing materials and particularly discloses an acidic leveling agent and a preparation method thereof. The acidic leveling agent is prepared from the following components by weight percent: 10.0%-20.0% of an emulsifying agent, 20.0%-45.0% of fatty amine, 8.0%-10.0% of sulfamic acid, 5.0%-8.0% of fatty alcohol, 3.0%-5.0% of urea and the balance of water. The preparation method comprises the following steps: adding the raw materials except water into a reaction kettle in sequence according to the formula and stirring; when adding each type of raw material, stirring for 20-25 minutes; weighing the water amount needed in the formula and adding into the reaction kettle; stirring and reacting for 1 hour; and after finishing, standing and filtering and discharging materials. The acidic leveling agent disclosed by the invention has extremely good diffusivity and mobility, so that dye molecules are uniformly combined with fiber molecules in a dyeing process; the acidic leveling agent is wide in applicability, good in effect and environmentally friendly; and compared with a traditional formula, the agent has the advantages that 10%-15% of the cost is reduced.

The invention relates to a prescription of an anti-yellowing agent and in particular relates to a prescription of a anti-yellowing agent for fibers (such as nylon and nylon elastic fiber). The anti-yellowing agent is characterized by comprising the following components in parts by weight: 10.0-20.0 parts of an emulsifying agent, 20.0-50.0 parts of sulfonic acid, 10.0-40.0 parts of alcohols and the balance being 40.0-10.0 parts of water. The cost of the prescription of the anti-yellowing agent is low and reduced by 10-15% in comparison with the cost of imported finished products, and the anti-yellowing agent has a good anti-yellowing effect. The anti-yellowing agent has the advantages of no formaldehyde, no heavy metal ions, no teratogenesis, no mutagenesis, no carcinogenic actions, no toxic side effect on a human body, conforms to the requirements of the EU (European Union) OeKo-TEX Standard 100 and the requirements of the REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) standard, and can well keep the whiteness and the vividness of fabrics.
