Problems solved by technology

However, the preparation process of this method is long, and the prepared heating fiber has high requirements on equipment, and the process is complicated, resulting in an increase in cost
In addition, there is also a technology to design the fabric structure of textiles, using the textile material to absorb moisture and heat while using the structure of the fabric to achieve heat preservation. In this technology, the moisture absorption and heat generation temperature of the fiber material and the scope of application have great limitations.

preparation example Construction

[0039] A method of preparing a photopolymer textile, a textile is a fiber, a yarn, a woven fabric, a knitted fabric, and a nonwoven fabric. Includes the following steps:

[0040]Preparation of S1, photopolymerized compound powder

[0041] The natural powder was stirred in a mixed solution of the alcohol organic solvent and water, and then the photon heat generating nanom material was added for 30 to 120 min, and the stirring temperature was 25 ~ 90 ° C, and the filtration was taken in sequence, and washed multiple times. Drying treatment at 60 ~ 120 ° C to obtain a photopolymerized compound powder;

[0042] Specifically, the mass ratio of the photoelectric heat generating nanomaterial and the natural powder is 0.15% to 25%, and the natural powder is a wool powder, silk powder, cotton powder and lignin powder. The photoconductive nanomaterial is one or more of graphene, carbon nanotubes, oxide oxide, MXENE, boron nitride, polypyrrole, polyaniline, and polyoxamine. The amount of the...

Embodiment 1

[0053] This embodiment provides a method of preparing a photopolymer textile, and a textile is a polyester yarn, and specifically includes the following steps:

[0054] Preparation of S1, photopolymerized compound powder

[0055] The silk powder was placed in a mixed solution of ethanol and a water volume ratio of 1: 5, and then the oxide graphene nano material was added for 40 min, the stirring temperature was 60 ° C, filtered, washed multiple times, 90 ° C Dry treatment to obtain a grapy oxide inkylene silk photoreficiency compound powder;

[0056] Among them, the mass ratio (OWF) of the oxide oxide and the silk powder is 3%, and the yolstone oxide inkylene silk photoresist composite powder and the bath ratio of the mixed solution are 1:50.

[0057] Preparation of S2, Photoelectric Slurry

[0058] The chitosan was added to the deionized water to dissolve, then the binder was added to the uniform, and finally the oxide in graphene silk photoresist heat generating compound obtaine...

Embodiment 2

[0070] Example 2 provides a method of preparing a photopolymer textile, compared to Example 1, in which the mass ratio (OWF) of graphene and silk powder in step S1 is 1%, the rest is Example 1 is roughly the same, and details are not described herein.

[0071] See Figure 5-6 Distance Figure 5 An electron microscope diagram of the photopolymerized compound prepared for Example 2, Image 6 The photopolymer polyester yarn electron microscopy is prepared. from Figure 5 It can be seen that the composite effect of silk powder and graphene nano material is better; Image 6 The polyester yarn surface load OWF is 1% oxide in graphene silk photoresist heat composite powder, and its load effect is better.

[0072] See Figure 7 Distance Figure 7 A light reflectance result diagram of a 1% oxide oxide silk powder in Example 2 in Example 2 in Example 1. It can be seen that the silk powder has the strongest absorption capacity of the light. From the experiment, although the soil powder has high abs...

Abstract

The invention provides a preparation method of a photo-induced heating textile, the preparation method comprises the following steps: loading a photo-induced heating nano material on natural powder to obtain photo-induced heating composite powder, and finishing the photo-induced heating composite powder on the textile in a padding manner under the action of a thickener and an adhesive to obtain the textile with photo-induced and photo-thermal functions. The natural powder is beneficial to the adhesion of the photoinduced heating nano material on the surface of the textile and the absorption of light so that the hygroscopicity and the comfort of the textile are improved; the photo-induced heating nano-material not only enables the textile to realize efficient photothermal conversion, but also can improve the strength, wear resistance and toughness of the textile and prolong the service life of the textile due to good strength and toughness of the photo-induced heating nano-material. The photo-induced heating textile prepared by the method has high photothermal conversion efficiency and good use performance, and overcomes the defects of the traditional heating textile; and the method is short in process period, low in production cost, wide in application range and high in practicability, and has a relatively good industrial application prospect.

Description

Technical field [0001] The present invention relates to the field of fabrication of functional textiles, and more particularly to a method of preparing photopolymerized textiles. Background technique [0002] Textiles refer to fibers and fiber products, specific as fibers, yarns, fabrics, and composites thereof. "Fiber and fiber products" indicate that the textile is both a raw material for textile machining, and another product is a fiber aggregate processed by textile machining. Textile materials are an important part of soft material materials, which are widely used in clothing and daily use of textiles. [0003] With the development of society and the improvement of living, people are increasingly required for clothing and daily textiles, not only require clothing to have aesthetic, comfort and wear resistance; also requires more specific functions, of which Includes fever thermal insulation. Heating costumes have great advantages in winter, and the cold and other aspects can...
