A kind of production technology of anti-ultraviolet sportswear Jin ammonia air-covered silk

Abstract

The invention discloses a production technology of chinlon spandex air-coated yarn used for anti-ultraviolet gym suits. The chinlon spandex air-coated yarn produced by the technology is provided with good ultraviolet resistance performance and breathable and relaxing experience can be kept for a long time; the generation and aggregation of static electricity can be effectively reduced so that the skin is protected and therefore the production technology is promoted and applied in outdoor gym suits fabrics.

Description

Technical field

[0001] The invention relates to the technical field of chemical textiles, in particular to the technical field of a production process of nylon ammonia air-coated silk for anti-ultraviolet sportswear.

Background technique

[0002] With the continuous expansion of the demand for textile fabrics, various special fibers, special processing techniques, and special-style yarns have emerged. Nylon ammonia air-covered yarn is a popular special yarn in the market in recent years. It is made of spandex yarn as the core, which is wrapped and compounded with nylon filament. The interweaving of spandex and nylon not only enables the fabric to be dyed at normal temperature and pressure, avoiding damage to the fabric due to high temperature and high pressure, but also makes the knitted fabric moisture-absorbing, breathable, soft, elastic and resilient, satisfying people's desire for comfortable clothing. , close-fitting and maintaining the same shape requirements, are...

Embodiment Construction

[0018] A kind of production technology of the present invention's anti-ultraviolet sports wear Jin ammonia air-coated silk, comprises the following steps successively:

[0019] Step 1: Feed nylon slices, titanium dioxide, charcoal fiber, polyethylene wax, zinc chloride and sodium sulfate into the silo under nitrogen protection, enter the extrusion system, and heat through various sections in the extruder, at 265-285 ℃ melting and stirring to make nylon stock solution and keep it warm;

[0020] Step 2: The nylon stock solution prepared in step 1 is filtered through coarse sand and fine sand and then sent to a metering pump. The metering pump transports the nylon stock solution to the spinning box, and the spinning box sprays the nylon stock through the spinneret;

[0021] Step 3: Cooling the nylon raw yarn prepared in step 2 by side blowing, the cooling air temperature is 20-22°C, the ambient humidity is 70-79%, and the cooling wind speed is 0.8-1.0m / s;

[0022] Step 4: Evenly...
