The real silk fiber has the reputation of 'fiber queen' in the past, and is favored by people who are ancient times with the unique charm. Modern people also endow the silk fabric with health-care fibers, wherein the silk fabric contains 18 amino acids which are necessary for human bodies, and the amino acids are almost the same as the amino acids contained in human skins. Therefore, it is also called "second skin" of human. Meanwhile, tryptophan and tyrosine in silk protein can absorb ultraviolet rays, prevent the radiation of the ultraviolet rays, enhance the activity of skin cells on the body surface and promote the metabolism of the skin cells, and the natural function that the artificial fiber is not dust-resistant and can not reach also lays a precious value and a nonsubstituted status of silk products. Especially silk home textile products are favored by people. The silk fabric is suitable for manufacturing high-grade fabrics which are in direct contact with skin, such as clothes, scarves, eyepatches, masks, sun-proof masks and bedding. However, in the process of using and wearing the silk fabric, the silk fabric is easy to stick flying hair and dust like other common fabrics, and can adsorb dust-like dry dirt like mascara, powder cake, blush and eye shadow, thereby affecting the make-up of ladies.

The bath ratio of the water-repellent and oil-repellent finishing agent in the step 2) is 20g/L, and the bath ratio of the dry-pollution-prevention finishing agent is 30g/L; the water-repellent oil-repellent finishing agent and the dry-stain-proof finishing agent are mixed according to the mass ratio of 1:1.5 addition.
The anti-dry-pollution finishing agent in the step 2) is a polysiloxane derivative.
The anti-dry-pollution finishing agent is a finishing agent BAYPROTECT DSR.
The weak acid is acetic acid or citric acid.
And 2) the water-repellent and oil-repellent finishing agent is a BAYGARD CLEAN.
The drying operation in the step 3) is as follows: drying at 90-100 ℃.
The padding working solution in the step 2) is specifically operated as follows: the speed of the process is 20 to 25m/min, and the temperature of the working solution is 20 to 30 ℃ by adopting a one-dip-one-roll mode.
The temperature of the tentering and setting in the step 3) is 120-130 ℃, and the vehicle speed is 30-35m/min.
Preferably, when the working solution is padded in the step 2), the temperature difference between the temperature of the real silk fabric and the temperature of the working solution is less than or equal to 20 ℃. And (3) when the temperature of the fabric is monitored, inserting a thermometer into the real silk fabric rolled in the step 1), and measuring the temperature of the real silk fabric.
Preferably, the equipment used in steps 2) and 3) is a tenter setting machine; the working solution is placed in the liquid tank; the liquid tank and the tentering setting machine are designed in a split mode, and the liquid tank is arranged in front of the tentering setting machine; alternatively, the liquid bath is connected to the front end of the tenter setting machine. And (3) carrying out step 2) padding of the working solution by the cooled fabric through a liquid tank, and then carrying out step 3) so as to realize continuous operation of the steps 2) and 3).
Compared with the prior art, the finishing process of the pollen-proof and anti-dry silk fabric and the preparation method thereof have the beneficial effects that:
1. the silk fabric obtained by the process is not easy to adsorb dry dirt of dust and pollen, and the dust and the pollen can be removed by lightly beating the silk fabric. Firstly, the applicant adopts high-temperature drying in the step 1) to ensure that the internal tissues of the silk fibers are loose and the surface micro-voids are increased, and the adhesion amount and the adhesion firmness of the anti-dry-stain finishing agent and the water-repellent and oil-repellent finishing agent on the surfaces of the silk fibers are improved during subsequent padding of working solution, so that the pollen-proof and anti-dry-stain characteristics of the silk fabric can be improved. Secondly, the applicant adds an anti-dry and anti-pollution finishing agent and a water and oil repellent finishing agent in the formula for combination; compared with the single use of the anti-dry-pollution finishing agent, the working solution is compounded with the anti-dry-pollution finishing agent and the water-repellent and oil-repellent finishing agent, so that the pollen-proof and anti-dry-pollution effects of the silk fabric can be obviously improved, and the washability of the fabric is also improved.
2. The silk fabric obtained by the process has good washability, and the luster of the surface of the silk is not damaged after finishing. Firstly, the fabric is different from other fabrics, the real silk fabric has special soft gloss, and the washing fastness and the gloss sense of the real silk are contradictory due to the using amount of the finishing agent; the finishing agent is excessive in dosage, the pollen-preventing and anti-drying effect is good, but the fabric is dull in luster and loses the fabric style peculiar to real silk; the finishing agent dosage is too small, and the effect of preventing pollen from drying and polluting is not obvious. The applicant confirms through research that the optimal dosage is 18 to 25g/L of the bath ratio of the water-repellent and oil-repellent finishing agent, and the bath ratio of the anti-dry finishing agent is 18 to 50g/L; the water-repellent oil-repellent finishing agent and the dry-stain-proof finishing agent are mixed according to the mass ratio of 1:1 to 2, the addition of the additive can ensure that the silk fabric has a good pollen-preventing and anti-drying effect and can keep the unique soft luster of the silk fabric. Secondly, the problem that the gloss of the surface of the silk fabric after finishing is apt to be mottled is confirmed by research of the applicant, and the problem is not obvious in indoor scattered light because the anti-dry-dirt finishing agent and the water and oil repellent finishing agent after padding are anti-stained on the silk fabric, and the mottled gloss of the surface of the silk fabric after finishing can be observed in an environment with a single light source or bright outdoor light. Further research confirms that in the prior art, the silk fabric dried in the step 1) is immediately padded with working solution, and even the working solution is placed in a liquid tank behind a dryer; when the dried high-temperature silk fabric is padded with the working solution, the finishing agent BAYPROTECT DSR heated at high temperature has strong adhesiveness and fluidity, so that reverse adhesion is generated in the subsequent process, and the gloss of the silk fabric is mottled, which is difficult to repair and can cause the silk fabric to be degraded or scrapped. Therefore, the applicant designs that in the step 2), the temperature of the real silk fabric is reduced to 15-45 ℃, the temperature of the working solution is 15-25 ℃, the temperature difference between the real silk fabric and the working solution is less than or equal to 20 ℃, the problem that the finished fabric has mottled gloss is avoided, and the adhesion of the finishing agent BAYPROTECT DSR to the fabric in the temperature range is good.
