And the other side can be woven by other common fibers, such as cotton, modified polyester fibers and the like. Therefore, the radiation protection function is realized, the discomfort caused by the direct contact of the metal fiber and the human body when the functional knitted fabric is worn is avoided, and the serviceability and the comfort of the functional knitted fabric are improved. The method of double-sided weaving can adopt a conventional weaving method, such as: the double-sided multi-track circular knitting machine is used for weaving and the like, so that the two sides of the circular knitting machine display front side coils, fisheye line graphs and the like, and the warm-keeping effect is enhanced.

Wherein, the nylon filament selected by the silver-plated fiber is 65D, the silver-plated fiber prepared after the silver-plating process is finished is 70D, and the content of the silver fiber is 30-32 percent.
However, since cotton has water shrinkage, special treatment is required at a later stage.
Example 2

The fabrics produced in the above examples 1 and 2 are oxidized even after being left in the air for a long period of time after being used, and even deteriorated by corrosion due to acidic substances such as sulfurous gas or nitric oxide remaining in the air. The common antioxidant treatment process is complex, high in cost and poor in effect. In order to improve the oxidation resistance, on the basis of the examples 1 and 2, a metal layer is formed on the surface of the silver fiber surface of the fabric in the form of ion plating (the ion plating can be magnetron sputtering, multi-arc ion plating and the like), and the metal layer is a titanium or titanium alloy layer; wherein, the ion plating is preferably multi-arc ion plating.

Wherein, the nylon filament selected by the silver-plated fiber is 65D, the silver-plated fiber prepared after the silver-plating process is finished is 70D, and the content of the silver fiber is 30-32 percent. The cotton yarn can be selected from 100% high count combed cotton yarn with count of 28S～80SE.g. 36S，40S，50S，60SAnd the like.
However, since cotton has water shrinkage, special treatment is required at a later stage.
Example 4
The double-sided knitted fabric is woven by using silver-plated fiber filaments and porel yarns and a double-sided multi-track circular knitting machine, wherein one side of the double-sided knitted fabric is woven by the silver-plated fiber filaments; and the other side is woven by using porel yarns which are called ultra-imitation cotton and have the functions of moisture permeability and temperature regulation. The Porel yarn is modified polyester short fiber, adopts a capillary cavity structure, and introduces hydrophilic groups and flexible chain segments simultaneously, so that the Porel yarn has the function of automatically adjusting moisture and heat balance. The porel yarn is available from tokyo fibers technologies development ltd, south kyo. Referring to fig. 1, in fig. 1, the 3 rd and 6 th paths are Porel yarns, and the 1, 2, 4 and 5 paths are silver-plated fibers.
Wherein, the nylon filament selected for the silver-plated fiber is 70D, the silver-plated fiber prepared after the silver-plating process is finished is 75D, and the content of the silver fiber is 35 percent.
The fabrics produced in the above examples 3 and 4 are oxidized even after being left in the air for a long period of time after being used, and even deteriorated by corrosion due to acidic substances such as sulfurous gas or nitric oxide remaining in the air. The common antioxidant treatment process is complex, high in cost and poor in effect. In order to improve the oxidation resistance, on the basis of the examples 3 and 4, a metal layer is formed on the surface of the silver fiber surface of the fabric in the form of ion plating (the ion plating can be magnetron sputtering, multi-arc ion plating and the like), and the metal layer is a titanium or titanium alloy layer; wherein, the ion plating is preferably multi-arc ion plating. Through the treatment, the metal titanium ions are plated on the surface of the silver fiber radiation-proof fabric to form a titanium protective film, so that the fabric is sweat-resistant, salt mist-resistant, oxidation-resistant, corrosion-resistant and anti-tarnishing, achieves the special performance of permanence and no deterioration, and greatly enhances the radiation-proof performance. The antioxidant treatment may be included in any process after the manufacture of the raw fabric, as long as the process conditions allow.
Example 5
The gray fabric woven in the embodiment 3 is firstly subjected to the anti-oxidation treatment, and then is subjected to pre-setting, pre-treatment and secondary qualitative treatment to obtain the finished fabric.
Example 6
The grey cloth woven in the embodiment 4 is firstly pre-shaped, pre-treated and secondarily qualified, and then is subjected to the anti-oxidation treatment to obtain the finished fabric.
Silver is an unstable element, so that the fabric is easily corroded in air or pretreatment liquid, and the fabric is blackened and hardened. Therefore, the pretreatment step of the invention is to add the auxiliary agent into the purified water in a closed overflow dyeing machine and treat the mixture for 30 to 60 minutes at the temperature of between 50 and 80 ℃.
In general, soft water is generally adopted for pretreatment of common fabrics, and considering that the fabrics of the invention contain unstable elements such as silver, acidic substances contained in air and pretreatment liquid are easy to corrode, so that the fabrics turn black and become hard. In order to avoid the above situations, the invention selects the purified water to carry out pretreatment processing on the fabric. The silver fiber is not acid-resistant and is easy to oxidize at high temperature, so that the low-temperature high-efficiency degreaser is selected.

The dyeing and finishing solves the following problems
1. Solves the problem that silver fiber fabric is easy to be oxidized
The radiation-proof finished fabric can be oxidized even if left acidic substances in the air such as sulfuration gas or nitric oxide and the like are corroded and deteriorated after being placed in the air for a long time, and in order to facilitate the permanent storage of the fabric, an arc-standing ion source welding technology is adopted in the aspect of after-finishing oxidation and deterioration resistance. The arc ion source welding technology is to weld metal titanium ions on the surface of the silver fiber radiation-proof fabric to form a titanium protective film, so that the fabric has the special performances of sweat resistance, salt mist resistance, oxidation resistance, corrosion resistance and discoloration prevention, and is permanently and nondegradable.
2. Improves the repeated washing fastness of the silver fiber fabric
After the radiation-proof fabric is washed by water, the radiation-proof performance is reduced, after the fabric is washed by water for many times, the radiation-proof performance is slightly obviously reduced, but after the fabric is subjected to waterproof finishing, the washing performance is enhanced. Multiple experiments show that the washing fastness of the fabric subjected to waterproof finishing is enhanced by 3-4 times compared with the fabric not subjected to finishing. The waterproof finishing process adopts a coating technology, and a permanent waterproof agent is applied to carry out secondary processing on the fabric, so that the permanent waterproof and washable performances are achieved.
