Description

Technical Field

[0001] The invention relates to the technical field of fabric preparation, and in particular to a process for preparing corrosion-resistant and anti-fouling composite fiber fabric. Background Art

[0002] The fiber fabric is a small ingot knitted structure, woven on a large circular knitting machine. After weaving, the grey fabric is first dyed, and then processed by a variety of complex finishing processes such as napping, combing, and shearing. The front side of the fabric is napped, and the back side is sparse and evenly napped, with short fluff, clear texture, and good fluffy elasticity. The fiber fabric is generally 100% polyester, soft to the touch, and has been the preferred product for keeping warm in the past two winters in China.

[0003] Dyeing polyester fabrics usually requires the use of some special dyes and processes. Since polyester is a synthetic fiber, its surface is not easy to absorb moisture and dyes, so pre-treatment is needed to increase its dyeing performance. First, polyester fabrics need to be pre-treated to remove surface grease, impurities and other substances. This can be achieved through methods such as heat treatment or alkali washing. Next, polyester fabrics need to be pre-treated, that is, chemicals are used to increase their hydrophilicity and surface tension. This helps the dye penetrate into the fiber, thereby achieving a uniform dyeing effect.

[0004] Although the existing composite fiber fabrics have certain corrosion resistance and antifouling functions, their corrosion resistance needs to be improved, and their wear resistance also needs to be improved. Therefore, a corrosion-resistant and antifouling composite fiber fabric preparation process is proposed to solve the above problems. Summary of the invention

[0007] In a preferred embodiment, in step S2, the antioxidant is a hindered phenol antioxidant, the UV stabilizer is a benzotriazole, and the mildew inhibitor is a silicone mildew inhibitor.

[0008] In a preferred embodiment, in step S2, a mixer is used to mix the masterbatch 1 with a large amount of polyester fiber raw material, and a spinning machine is used for spinning. The speed of the mixer is set to 220-260 r / min, and the temperature of the mixer is set to 30-45°C.

[0009] In a preferred embodiment, in step S3, the nano material is nano silicon dioxide, and the anti-friction agent is polytetrafluoroethylene powder.

[0010] In a preferred embodiment, in step S3, a mixer is used to mix the masterbatch 2 with a large amount of polyester fiber raw material, and a spinning machine is used for spinning. The speed of the mixer is set to 300-320 r / min, and the temperature of the mixer is set to 40-50°C.

[0011] In a preferred embodiment, in step S4, the speed of the composite spinning machine is set to 20-25 m / min, and the setting temperature of the composite spinning machine is set to 160-180°C.
