S5, coiling, namely coiling the spun-laced non-woven fabric;
S6, bleaching, namely bleaching the spun-laced cloth by using a bleaching auxiliary;
The application relates to a preparation method of a spunlaced non-woven fabric with a function of balancing microecology, which comprises the following steps:
s7, washing, namely placing the water-spun-bonded non-woven fabric subjected to the desizing (or the water-spun-bonded non-woven fabric subjected to the desizing treatment obtained by the conventional process treatment) into a working tank for water washing neutralization treatment;
s8, soaking, namely after water washing is finished, continuously adding water and functional additives into the working tank, so that the spun-laced non-woven fabric is soaked into an aqueous solution containing the functional additives;

S11, winding and cutting, namely winding and cutting the water-jet non-woven fabric which is qualified in inspection to obtain the all-cotton water-jet non-woven fabric with the balance micro-ecological function.
After the spun-laced non-woven fabric passes through the washing step, the step of continuously soaking by using a washing working tank is utilized, and it can be understood that the effective components in the functional processing auxiliary agent can be completely soaked in the all-cotton spun-laced non-woven fabric by putting water and a certain content of functional auxiliary agent into the working tank, so that the all-cotton spun-laced non-woven fabric with the balanced micro-ecological function is prepared.
Further, in the washing step S7, the amount of water used for washing is 8 times the weight of the whole roll of spun-laced non-woven fabric; in the impregnating step S8, an aqueous solution containing a functional auxiliary agent with the mass fraction of 10% is used for carrying out impregnating treatment on the non-woven fabric after the water washing neutralization treatment; of course, in some embodiments, the non-functional non-woven fabric can also be impregnated and sprayed with functional auxiliary agents to prepare the all-cotton spunlaced non-woven fabric with the function of balancing microecology.
Specifically, in the washing step S7, alkaline substances existing in the previous bleaching process can be removed through washing, so that the effect of neutralizing PH is achieved; in the soaking step S8, a certain content of functional treatment auxiliary agent is used, so that the effective components in the functional treatment auxiliary agent can be completely soaked in the non-woven fabric after water washing neutralization treatment;
Specifically, the functional auxiliary agent disclosed by the application comprises the following raw materials in percentage by mass:
Activonol-LevaNA, octanoyl hydroxamic acid 5-15%, ethylhexyl glycerol 5-10%, octyl glycol 5-10% and water in balance.
Wherein Activonol-LevaNA is mainly chitosan, purchased from korea An Diang company, for promoting growth of beneficial bacteria and providing moisturizing function.
Octanoyl hydroxamic acid, an organic acid with strong fungus inhibition effect, purchased from chemical company, inc. of Shanghai, can exert bacteriostatic effect in neutral or acidic environment.
Ethylhexyl glycerol, purchased from chemical company of Shanghai, has moisturizing, growth and proliferation inhibiting, antiseptic and antiseptic effects.
The octyl glycol is purchased from chemical Co-Ltd of the Shanghai, and has the characteristics of conditioning skin and hair and the effects of preventing corrosion, preventing corrosion and improving efficiency.
The functional auxiliary agent is obtained by compounding the four raw materials in percentage by mass. Among the functional aids, the ethylhexyl glycerol and the octanoyl glycol can promote the antiseptic and bacteriostatic functions of the octanoyl hydroxamic acid, and Activonol-LevaNA can promote the growth of beneficial bacteria. Therefore, the functional auxiliary agent has low broad spectrum, can inhibit the growth of harmful bacteria, slow down the propagation of the harmful bacteria and promote the growth of beneficial bacteria. In addition, the octanoyl hydroxamic acid has high-efficiency chelation, inhibits active elements required by harmful bacteria, limits the environment required by the growth of the harmful bacteria, and can better inhibit the growth of the harmful bacteria when being dispersed in a product in an undissociated state, so the octanoyl hydroxamic acid needs to exert antibacterial efficacy in a neutral or acidic environment. Preferably, the functional auxiliary agent exerts a better antibacterial effect in an environment with a pH of 5-6, and the pH of the aqueous solution of the functional auxiliary agent is adjusted to 5-6 by adding citric acid, which is purchased from Shanghai chemical Co., ltd.
