Moisture-absorbing and heating knitted fabric with long-time controllable heating temperature and preparation method thereof

Abstract

The invention relates to a moisture-absorbing and heating knitted fabric with long-time controllable heating temperature and a preparation method thereof. The preparation method comprises the following steps of taking a three-layer moisture-absorbing, uniform and slow-heating fabric with a moisture-absorbing gradient as a basic fabric; and preparing the moisture-absorbing and heating knitted fabric with the long-time controllable heating temperature by adopting a fabric padding-fabric single-side printing composite finishing process or a cheese dipping-fabric double-side printing composite finishing process. According to the fabric, under the environment conditions of constant low temperature and constant high humidity, the time for continuous heating and temperature rising to the highest temperature rise value is 510 s or above, and the synchronous rate of moisture absorption and heating achieved through moisture storage to the highest temperature rise value and the highest moisture storage amount is 95% or above; and under the constant environmental conditions of low temperature and gradual low humidity to high humidity, the time for continuously heating and raising the temperature to the highest temperature rise value is more than 260 seconds, and the heating area higher than the average temperature rise value when the temperature is raised to the highest temperature accounts for 70% or above of the total heating area. The method is simple, effective and wide in application range.

Description

technical field [0001] The invention belongs to the technical field of high-quality heat-humidity comfortable textiles, and relates to a moisture-absorbing and heat-generating knitted fabric whose heating temperature can be controlled for a long time and a preparation method thereof. Background technique [0002] Textile materials, as the second skin of the human body, establish an adjustment system between the outdoor environment and the human skin, so that the comfort requirements of the human body wearing clothing focus on the fact that the clothing can be sensitive to the skin in any active state. The temperature and humidity changes in the environment are quickly sensed and responded in a timely manner, repairing and establishing the heat and humidity balance of the microenvironment where the human body is located, and providing the human body with a suitable experience of heat and humidity comfort. [0003] In recent years, people uphold the concept of green life and p...

Problems solved by technology

[0010] The purpose of the present invention is to aim at the method for controlling the temperature of fabric moisture absorption and heating to rise slowly and evenly in the prior art except spinning and weaving fields, and there is no method of weaving, dyeing and finishing combined effect to delay the delay of moisture absorption and heating Feasibility and heating uniformity control technology under the premise of slow heating, and the resulting moisture absorption and heating fabrics still heat up too quickly, causing the fabric to heat up rapidly, and the moisture storage function is not fully realized, resulting in difficulty in delaying heating, concentrated heating, localized heating To solve the problem of uneven heat, a kind of moisture-absorbing and heating knitted fabric based on long-term controllable heating temperature and its preparation method are provided; the moisture-absorbing and heating knitted fabric with long-term controllable heating temperature of the present invention has inner layer - diffusion , The middle layer-strong moisture storage, the outer layer-a "ladder" type three-layer composite structure that guides uniform moisture absorption and heat generation, combined with the composite effect of textile and dyeing and finishing, and finally achieves the long-term controllability of the moisture absorption and heat generation temperature of the fabric
