Technical Field

The invention belongs to the field of textile processing, and particularly relates to a preparation method of a cool feeling enhancing fabric.

Background

Along with the development of social economy and the change of life style, people put forward higher and higher requirements on the comfort of fabrics, particularly the heat and humidity comfort, wherein cool fabrics are widely concerned because the cool fabrics can bring cool experience to human bodies in hot summer. At present, the method for preparing the cool fabric on the market mainly comprises cool fiber and cool after-finishing. The former mainly obtains instant cool feeling by adding mineral materials such as mica stone and the like in the spinning process to improve the thermal conductivity of the fiber, but the effect of continuous cool feeling is difficult to realize, and the spinning method has higher cost; the traditional after-finishing is mainly to prepare a cool feeling finishing agent by using factors which absorb heat and retain moisture when meeting water, such as xylitol, erythritol, menthone, silk fibroin and the like, and finish the cool feeling on the fabric, but the fabric is easy to lose effectiveness when washed by water, and the volatility of partial substances greatly shortens the use time efficiency and influences the wearing experience of a human body, so that the fabric which can bring cool experience to the human body for a long time is urgently needed. In the prior art, the slow-release microcapsule greatly prolongs the duration time of the cool feeling effect because the slow-release microcapsule slowly releases the cool feeling factors and can be effectively combined with clothes, and on the other hand, the slow-release microcapsule absorbs heat in cooperation with the phase transformation of the phase-change microcapsule, so that the instant cool feeling and the continuous cool feeling effect of a human body can be effectively increased.

In the actual use process, the single cool finishing is not enough to relieve the sticky feeling and the skin-sticking uncomfortable feeling of the fabric caused by high-humidity weather or a large amount of sweating. In order to improve the situation, people usually prepare the moisture-absorbing and sweat-releasing fabric by increasing the evaporation area and increasing the water guide channel, so that the human body can quickly drain the moisture of the fabric in a high-humidity environment or under a large amount of sweat-releasing conditions, and the cooling and comfortable feeling of the human body can be improved. Patent CN201911408050.2 discloses a method for preparing a knitted fabric combining moisture absorption, sweat releasing and cool feeling, which can increase water guide channels by designing a fabric weave structure while finishing cool feeling, thereby enhancing the cool feeling effect. However, the research on enhancing the cool feeling effect by utilizing moisture absorption and sweat releasing is rare at present, and the development is lagged. At present, a lot of cool fabrics in the market only have instant contact cool performance, but do not have a lasting cool effect; the effect of cool feeling is insufficient due to single action mode or limited loading amount; because sweat and heat generated by the human body cannot be taken away in time, the sticky dampness and sultry discomfort caused by the sweat and heat cannot be relieved.

Therefore, the cool feeling enhancing fabric is developed and applied to sportswear, casual clothes, protective clothing, hats and socks and the like, has a long-time efficient cool feeling effect, and can enhance the cool feeling effect in a synergistic manner by enhancing the loss of moisture, so that the cool feeling enhancing fabric has important significance for enhancing the cool experience and the overheat protection of a human body in severe environments.
