Embodiment 1

[0031] Prepare a thermochromic masterbatch capable of changing from red to colorless at about 37°C. Then dry the thermochromic masterbatch at 80°C for 2 hours, and dry the polyester resin chips at 120°C for 4 hours, then weigh 3% of the thermochromic masterbatch, 60% of the core material polyester, and 60% of the skin polyester. Resin 40%. It is mixed evenly, melt-spun, drawn, stretched, and wound into filaments. The spinning speed is 900m / min, and the temperature of each zone of the spinning machine is as follows: zone 1, 250°C; zone 2, 255°C; zone 3, 260°C; zone 4, 265°C; head temperature 265°C, host speed 12r / min , the traction speed is 4000r / min, and finally a polyester fiber that can change from red to colorless at 37°C is obtained.

Embodiment 2

[0033] Prepare a thermochromic masterbatch capable of changing from golden yellow to fluorescent yellow at about 27°C. Then dry the thermochromic masterbatch at 80°C for 2 hours, and dry the polyester resin chips at 120°C for 4 hours, then weigh 3% of the thermochromic masterbatch, 50% of the core material polyester resin, and 50% of the polyester resin in the skin layer. 40% ester resin, 0.5% antistatic agent, mix the thermochromic masterbatch and the core material polyester resin evenly, mix the antistatic agent and the cortex evenly, then melt spinning, pulling, stretching, and winding into filaments . The spinning speed is 880m / min, and the temperature of each zone of the spinning machine is as follows: zone 1, 235°C; zone 2, 255°C; zone 3, 265°C; zone 4, 270°C; head temperature 270°C, host speed 13r / min , the traction speed is 3800r / min, and finally the polyester fiber that can change from golden yellow to fluorescent yellow at about 27°C is obtained.

Embodiment 3

[0035] Prepare thermochromic powder that changes from purple to blue at about 30°C. Dry the thermochromic masterbatch at 90°C for 2.5 hours, dry the polyester resin chips at 100°C for 5 hours, then weigh 5% of the thermochromic masterbatch, 40% of the core material polyester resin, and 40% of the skin layer polyester 45% resin, 0.5% antistatic agent, mix the core material and thermochromic masterbatch evenly, melt spin according to the skin-core structure, draw, stretch, and wind into filaments. The spinning speed is 1000m / min, and the temperature of each zone of the spinning machine is as follows: zone 1, 245°C; zone 2, 255°C; zone 3, 265°C; zone 4, 270°C; head temperature 270°C, host speed 13r / min , the traction speed is 3500r / min, and finally a polyester fiber that can change from purple to blue-yellow at about 30°C is obtained.

Abstract

The invention provides a thermochromic polyester fiber and a preparation method thereof.The thermochromic polyester fiber is prepared from 1%-5% of thermochromic masterbatch, a polyester fiber material and other auxiliaries.The thermochromic polyester fiber can be of a skin-core structure, wherein a skin layer accounts for 40%-60% of the cross section area of the fiber, the cross section area ratio of the skin layer to a core layer is (4:6)-(6:4), and therefore the strength and the color and luster of the fiber can be guaranteed.A melt spinning method is adopted as the preparation method of the thermochromic polyamide fiber and comprises the steps that the thermochromic masterbatch, polyester chips and the other auxiliaries are fully dried, a core material and the thermochromic masterbatch are mixed to be uniform in proportion, the mixture and the skin layer are melted separately, and the fiber with the skin-core structure is formed through a spinneret.The thermochromic polyester fiber can be applied to various textiles such as garments, home textiles, industrial fabrics and the like and is very wide in application range.

Description

technical field [0001] The invention relates to a fiber and a preparation method thereof, more specifically to a thermochromic polyester fiber and a preparation method thereof. This thermochromic fiber can change color at a certain temperature. Background technique [0002] In real life, polyester fiber occupies a very important position in the textile field. At the same time, more and more smart textiles have entered people's lives, and temperature-sensitive and color-changing textiles have gradually appeared in people's vision. Nowadays, thermochromic textiles are mostly obtained by thermochromic coating or thermochromic paste printing on finished fabrics. This method limits the application range of thermochromic materials to a large extent, and Coating or printing will affect certain properties of textiles to a certain extent. Contents of the invention [0003] The present invention aims at inventing a polyester fiber capable of temperature-sensing and discoloration,...
