Embodiment 1

[0032] This embodiment discloses a method for preparing photochromic fibers, specifically:

[0033] The photochromic fiber is a fiber with a skin-core structure prepared by a blending melt spinning method, and the mass of the core layer is 35% by weight of the mass of the photochromic fiber, wherein the raw materials of the skin layer include polyester resin and polyester resin. Antioxidant with a resin mass percentage of 5%; the core layer raw materials include polyester resin, photochromic particles with a mass percentage of 3% of the polyester resin, and an oxidant with a mass percentage of 8% of the polyester resin . The antioxidant is antioxidant 1010.

[0034] Specifically, the photochromic particles are indoline spiropyran.

[0035] Specifically, the blending melt spinning method comprises the following steps:

[0036] 1) Add the raw material of the skin layer to the single-screw extruder for extrusion; the temperature of each zone of the single-screw extruder is: 12...

Embodiment 2

[0045] This embodiment discloses a method for preparing photochromic fibers, specifically:

[0046] The photochromic fiber is a fiber with a skin-core structure prepared by a blending melt spinning method, and the mass of the core layer is 40 wt% of the mass of the photochromic fiber, wherein the raw materials of the skin layer include polyester resin and polyester resin. Antioxidant with a resin mass percentage of 5%; the core layer raw materials include polyester resin, photochromic particles with a mass percentage of 7% of the polyester resin, and an oxidant with a mass percentage of the polyester resin of 6% . The photochromic particles are indoline spiropyran. The antioxidant is antioxidant 1010.

[0047]Specifically, the blending melt spinning method comprises the following steps:

[0048] a) Add the raw material of the skin layer into the single-screw extruder for extrusion; in step a), the temperature of each zone of the single-screw extruder is: 123°C in zone I, 12...

Embodiment 3

[0057] This embodiment discloses a method for preparing photochromic fibers, specifically:

[0058] The photochromic fiber is a fiber with a skin-core structure prepared by a blending melt spinning method, and the mass of the core layer is 45 wt% of the mass of the photochromic fiber, wherein the raw materials of the skin layer include polyester resin and polyester resin. Antioxidant with a resin mass percentage of 6%; the core layer raw materials include polyester resin, photochromic particles with a mass percentage of 8% of the polyester resin, and an oxidant with a mass percentage of 7% of the polyester resin . The photochromic particles are indoline spiropyran. The antioxidant is antioxidant 1010.

[0059] The blended melt spinning method comprises the following steps:

[0060] 1) The skin layer raw material is added to the single-screw extruder for extrusion; the temperature of each zone of the single-screw extruder in step 1) is: 121°C in zone I, 125°C in zone II, 130...

Abstract

The invention discloses a method for preparing photochromic fabric. The photochromic fabric is formed by interweaving of warps and wefts. The warps are photochromic fiber and polyester fiber blended yarn which comprises 45-65 wt% of photochromic fiber, the wefts are polyester fiber and cotton fiber blended yarn which comprises 45-65 wt% of polyester fiber, and the specification of the warps and the wefts is 100-135 dtex / 40F. The color of the photochromic fabric changes along with the change of the light condition, so that the fabric has more colors; besides, through pattern arrangement and color design during weaving, the situation that the style of a traditional set of printed home textiles is changeless is changed, and the aesthetic fatigue of consumers on the product is reduced.

Description

technical field [0001] The invention relates to the field of textiles, in particular to a photosensitive fiber and its application in home textile products. Background technique [0002] With the improvement of people's living standards, the pursuit of home textile products is not only for keeping warm, but people's requirements for its beauty and comfort are also constantly improving. At present, the bedding products on the market mainly meet the needs of consumers by changing the design of product patterns and styles. In my country, home textile products are used for a long time, which will inevitably cause visual fatigue. [0003] Nowadays, people have successfully developed a chemical fiber that can automatically change color by using the principle and high technology of bionics, which is called photochromic fiber. It is a method of introducing a photochromic compound into the fiber, or synthesizing a polymer spinning method that can change color. For example, sulfur d...
