Embodiment 1

[0009] Production of inorganic nano-photoresponsive self-cleaning polyester fibers with a denier of 1.56 (dtex).

[0010] Add the specially-made inorganic nano-photoresponsive self-cleaning functional masterbatch to polyester chips at a weight percentage of 12%, and carry out vacuum drying. First, keep the temperature at 60°C for 1 hour, then raise the temperature to 80°C for 1 hour, and then heat up Heat at 100°C for 2 hours, heat up to 120°C for 2 hours, heat up to 160°C for 3 hours, gradually raise the temperature to 200°C and hold until dry crystal slices are obtained. The drying process generally takes 14 hours. Use the existing spinning equipment, that is, spin on the LHV451 spinning machine, and then wind and shape it into virgin fibers. The spinning temperature is 278°C, and the winding speed is 1250m / min. Drafting on the drafting machine, the draft ratio is 3.6 times, to obtain 1.56dtex inorganic nano photoresponsive self-cleaning polyester fiber.

Embodiment 2

[0012] Production of hollow inorganic nano light-responsive self-cleaning polyester fibers with a denier of 6.67 (dtex).

[0013] Add the special inorganic nano light-responsive self-cleaning functional masterbatch to the polyester chip at a weight percentage of 16%, and then vacuum-dry it. First, keep the temperature at 60°C for 1 hour, and then raise the temperature to 100°C for 2 hours. , heat up to 120°C for 2 hours, heat up to 160°C for 3 hours, gradually raise the temperature to 200°C and keep warm until dry crystal slices are obtained. The drying process generally takes 14 hours. With the existing spinning equipment, that is, spinning on the LHV451 spinning machine, the spinning spinneret used is a hollow spinneret, and then wound into as-spun fibers, the spinning temperature is 276 ° C, and the winding speed is 1300 m / Min, the raw fibers of the first sound were bundled and drawn on the LHV903 post-drawing machine with a draw ratio of 3.4 times to obtain a 6.67dtex hol...

Embodiment 3

[0015] Production of inorganic nano-photoresponsive self-cleaning polyester fibers with a denier of 7.78 (dtex).

[0016] Add the special inorganic nano light-responsive self-cleaning functional masterbatch to the polyester chip at a weight percentage of 15%, and vacuum-dry it. First, keep the temperature at 60°C for 1 hour, and then raise the temperature to 80°C for 1 hour. , heat up to 120°C for 2 hours, heat up to 160°C for 3 hours, gradually raise the temperature to 200°C and keep warm until dry crystal slices are obtained. The drying process generally takes 14 hours. Use the existing spinning equipment, that is, spin on the LHV451 spinning machine, and then wind and shape it into virgin fibers. The spinning temperature is 280°C, and the winding speed is 1250m / min. Drafting on the drafting machine, the draft ratio is 3.4 times, to obtain 6.67dtex inorganic nano photoresponsive self-cleaning polyester fiber.

Abstract

The invention provides a production method of inorganic nanometer light response type self-cleaning polyester fiber, comprising the following steps of: firstly specially producing visible light response type photochemical catalyst and easily-dispersed functional self-cleaning master batch, mixing the specially-produced functional master batch with polyester chip, and producing the inorganic nanometer light response type self-cleaning polyester fiber by a polyester fiber production technology. On the premise that the physical and chemical properties and the spinnability of the conventional fiber are not changed, the inorganic nanometer light response type self-cleaning polyester fiber has the characteristics such as bacteriostasis, air cleaning, self-cleaning function of easily desorbing greasy dirt, wide reaction condition, economical efficiency and the comprehensive treatment on pollutants. The various textiles made from the fiber, such as curtains, tablecloth, sofas, bedclothes and clothes, just like automatically running air cleaners, can be widely used in places such as bedrooms, hotel rooms, hospital wards, office, shopping malls, restaurants, indoor recreation grounds, etc.

Description

technical field [0001] The invention relates to the textile industry, in particular to a method for manufacturing inorganic nanometer light-responsive self-cleaning polyester fibers in the field of synthetic fiber production. Background technique [0002] With the continuous improvement of the quality of life and the deepening of health awareness, people have higher and higher requirements for ambient air quality. However, the overall pollution of the atmosphere is becoming more and more serious, and various viruses such as influenza spread by droplets are rampant. Most of the time people spend time indoors, and a large number of heating and cooling equipment is used to make indoor life tend to be "closed", resulting in poor air circulation and easier spread of viruses. In addition, the extensive use of chemical building materials and decoration materials has aggravated the deterioration of indoor air, and it is imminent to improve indoor air quality. The various textiles i...
