A kind of method for preparing fabric with gradient water retention function

Abstract

The invention discloses a composition for preparing coating slurry and a preparation method of a fabric. Three compositions for preparing the coating slurry are prepared according to different coating modes; the reverse side of a cotton-containing base fabric is coated through three coating techniques including a roller, mould or plain net technique, a foam coating technique and a spray coating technique, wherein the vehicle speed is 15 to 30m / min; the application amount of the coating slurry is 25 to 35 percent of the weight of the fabric; baking is performed for 1.5 to 3.5min at the baking temperature of 150 to 170 DEG C; finally hydrophilic setting is performed by adopting a setting machine, wherein the vehicle speed of the setting machine is 15 to 20m / min, and the drying temperature for setting is 150 to 170 DEG C. By adopting the fabric prepared by the technique provided by the invention, a gradient water-retaining function of the fabric in the thickness direction is realized, a siphon-like effect can be realized through the water-retaining power difference, so that a persistent one-way moisture conducting function is formed, when a human body sweats, moisture on the fabric can realize gradient transfer from inside to outside, so that the fabric is ensured to have the functions of quickness in perspiration and comfort in wearing.

Description

technical field [0001] The invention relates to the field of fabrics, in particular to a method for preparing fabrics with gradient water-retaining functions. Background technique [0002] The invention relates to a fabric with a moisture control function, which can control the water content to form a gradient distribution in the thickness direction of the fabric, reduce the wet feeling of the pro-wear part and improve the evaporation efficiency, so as to achieve the purpose of improving comfort. [0003] Cotton-containing products are very popular because of their good comfort. However, cotton products have been criticized in this regard for their poor wearing comfort after moisture absorption and the fact that they are not easy to dry. How to improve the comfort of cotton products after moisture absorption has always been the goal pursued by textile practitioners. At present, the most commonly used technology is one-way moisture transfer, that is, printing or spraying on t...

Problems solved by technology

[0004] However, this method has the following limitations: due to the partial hydrophilic design, and the proportion of hydrophilic points is usually below 15%, and more than 85% are water-repellent points

Therefore, sweat can only find hydrophilic points and be absorbed after forming larger sweat droplets; if no larger sweat droplets are formed, the water will not be absorbed in time due to the water repellency of the fabric itself. Adsorption, thereby forming a sweat film on the skin, affecting the comfort of the wearer; in addition, the water repellent agent achieves the water repellent effect by relying on its own small interfacial tension, but the interfacial tension is easy to break due to the molecular water repellent chain during friction It is damaged, which leads to the weakening of the water repellency of the part, but its water retention has not been greatly affected, which is why the water repellent fabric will also be soaked and washed.

Therefore, the one-way moisture guide is only effective in the early stage of sweating, and will be completely soaked in the later stage like ordinary fabrics, which also affects the comfort of wearing
