The invention discloses a mud spot cleaning composition containing sodium octyl sulfonate and a preparation method of the mud spot cleaning composition. The composition comprises the following components in percentage by mass: protease, lipase, sodium dodecyl benzene sulfonate, sodium octyl sulfonate, cocamidopropyl betaine, tetradecyl dimethyl amine oxide, sodium polyacrylate, tetrasodium glutamate diacetate and deionized water. Through the synergistic decomposition effect of protease and lipase and in combination with the strong decontamination ability of the anionic surfactant, organic stains and inorganic particles in the mud spots are efficiently removed, and through sodium polyacrylate, dirt is prevented from being redeposited, and hardening of the washed fabric is reduced. The preparation method comprises the steps of heating and dissolving, compounding and stirring, adding an enzyme preparation at low temperature, adjusting pH and the like, and the prepared composition has the characteristics of strong detergency, mild clothing protection, hardening resistance and good environmental protection performance, and is suitable for cleaning mud spots of various fabrics.

The invention discloses an enzyme-organic silicon synergistic decontamination type furniture cleaning agent and a preparation method thereof. The core is a porous organic silicon microsphere integrated system loaded with compound enzyme and weak light response type photocatalytic particles. The porosity of the porous organic silicon microspheres is 60%-70%, enzymes and photocatalytic particles are loaded in double modes of chemical bonding and physical adsorption, the enzymes efficiently decompose organic stains during cleaning, the photocatalytic particles generate active oxygen under weak light to resist bacteria and remove odor, the pH value of the system is 6.5-7.5, and the multifunctional furniture cleaning agent is suitable for various furniture materials and free of damage. The cleaning agent realizes decontamination-antibacterial-residue-free dynamic synergy and light-enzyme relay synergy, the preparation process is mature and easy to scale, and the problems of single function, easy enzyme inactivation and material damage of a traditional product are solved.

This utility model relates to the field of lens technology and discloses a multi-point defocus lens, comprising: a base layer; a composite functional layer, including a reflective layer, an anti-fouling layer, and a wear-resistant layer arranged sequentially; and a defocusing structural layer, embedded in the base layer or the composite functional layer, including a honeycomb microlens array arranged in a honeycomb pattern, wherein the density of the honeycomb microlens array is ≥500 / cm². 2 The defocusing amount increases gradually from the center of the lens to the edge. Under ultraviolet light, the TiO2 coating in the anti-fouling layer can decompose more than 95% of organic stains (such as fingerprints and grease). After 1000 wiping tests, the light transmittance decreases. The nano-SiO2 coating has a hardness of 9H (pencil hardness) and excellent scratch resistance. Through plasma pretreatment, the composite functional layer has high adhesion to the base layer and is not prone to delamination even under large temperature differences. The composite layer solves problems such as anti-fouling and anti-scratch, and achieves synergy of multifunctional composite coating with excellent performance.

The invention relates to the technical field of sofa antibacterial fabric preparation, and particularly discloses a preparation process of a self-cleaning antibacterial fabric for an intelligent sofa, and the preparation process comprises the following steps: step 1, fabric substrate pretreatment: performing cleaning and surface activation treatment on a textile fabric substrate; step 2, preparation of an antibacterial finishing agent: preparing an antibacterial finishing liquid containing a nano antibacterial material and an adhesive; and step 3, functional finishing: dipping the fabric substrate pretreated in the step 1 into the antibacterial finishing liquid prepared in the step 2, and uniformly attaching the finishing liquid to the surface of the fabric fiber by adopting a padding process. According to the preparation process of the self-cleaning antibacterial fabric for the intelligent sofa, through the synergistic effect of the contact antibacterial function of nano-zinc oxide and the visible light catalysis self-cleaning function of the nitrogen-doped titanium dioxide coating, instant and long-acting dual dynamic protection is provided, organic stains can be effectively decomposed, bacterium breeding can be inhibited, and the cleaning and maintenance frequency is remarkably reduced.
