With consumers’ constantly increasing demands for the comfort of summer clothes, the functionality of textiles has gradually extended from the traditional moisture absorption and breathability to a more intuitive wearing experience. Among them, “cold sense” is becoming an important selling point for summer clothes, sportswear fabrics, knitted products and functional textiles.
For dyeing mills, textile mills and textile chemical purchasing enterprises, developing cold sense fabrics is not merely about imparting the fabric “cool” handle, but also requires simultaneous consideration of tough cold sense, hydrophilicity, color stability, auxiliary compatibility and adaptability to mass production. Dyeing mills need to control the risks of rework and customer complaints. Purchasing department should take into account product performance, environmental protection requirements and supply management. Engineers, on the other hand, need to pay attention to whether the cold sense son işlem maddesi can stably work on the machine, its compatibility with existing auxiliaries and its actual performance in the stentering process. Therefore, a cold sense finishing agent with touch cold sense, hydrophilicity, low yellowing, good compatibility and processing stability is more in line with the production demands of modern functional textiles.
Why Do Fabrics Need to Have Cold Sense Finishing?
Summer clothing and close-fitting textiles will directly contact with human skin when worn. When the skin contact with fabrics, the heat transfer between fabric and human body can affect consumers’ perception of whether the fabric is “cool” or “hot”.
The cool experience of traditional textiles is usually related to the type of fibers, fabric structure, thermal conductivity, moisture absorption and breathability. For example, some light, thin and breathable fabrics can improve wearing comfort through good air circulation and moisture transfer.
However, for ordinary fiber fabrics, just relying on the characteristics of fibers themselves is difficult to continuously meet the market’s demand for functional cold sense products.
Therefore, to impart fabrics touch cold sense by finishing becomes an effective method for dyeing mills to develop functional summer fabrics.
Compared with the re-development of special functional fibers, finishing has the characteristics of flexible application and convenient process adjustment. For textile enterprises that already have mature dyeing and stentering production lines, they can add cold sense finishing process on their existing production basis, thereby further developing summer fabrics with differentiated functions.
What Is Tough Cold Sense of Fabrics?
Cold sense does not equate to a decrease in the temperature of the fabric itself.
When human skin comes into contact with fabric surface, if the fabric can remove part of the heat from the skin surface in a short time, the human body will feel instant coolness. This cold sense that occurs instantly upon contact is closely related to the heat transfer process between the fabric and human body.
Therefore, for functional clod sense fabrics, judging whether it is “cold” merely by handle is not sufficient to serve as a complete performance evaluation.
In the textile industry, the instant touch cold sense can usually be evaluated through relevant testing methods, among which qmax (touch cold sense coefficient) is one of the important performance indexes.
Aiming at the instant cold sense of textiles, GB/T 35263-2017 Test ve Evaluation of the Instantaneous Touch Cold Sense of Textiles provides corresponding test and evaluation basis.
For dyeing mills’ engineers who hope to develop cold sense fabrics, it means that choosing a cold sense finishing agent not only needs to focus on the actual touch but also needs to verify the functionality after finishing through standardized tests.
Why Does It Need to Pay Attention to both Cold Sense and Hydrophilicity Simultaneously?
For summer textiles, cold sense is not the only important function.
The human will easily sweat at high temperature. Therefore, summer clothing, sportswear, casual wear and close-fitting fabrics usually also need to have good moisture absorption, hydrophilicity and comfort performance.
If the finishing agent can bring a certain cold sense but at the same time reduce the hydrophilicity of t fabric, it may affect the water absorption rate of fabric and the wearing experience.
Therefore, an excellent cold sense finishing agent should try to achieve a balance between cold sense and hydrophilicity as much as possible.
For sports fabrics, the fabric needs to quickly process the sweat produced by human body during exercise. For summer knitted fabrics, good hydrophilicity helps to improve wearing comfort. For close-fitting clothing and home textile products, hydrophilicity is also an important factor affecting the user experience.
Thus, when conducting cold sense finishing, we should not only focus on qmax, but also comprehensively evaluate the hydrophilicity, handle and final performance of the fabric.
Low Yellowing and Low Shade Changing Are Also Important to Cold Sense Fabrics
Functional finishing usually requires heat treatment processes such as drying and stentering. Therefore, the thermal stability of finishing agent itself and its impact on the color of fabric are key issues that dyeing mills need to consider when choosing products.
Especially for white, beige, light gray and other light-colored fabrics, any obvious yellowing may affect the appearance of the final product.
For export-oriented textile enterprises, such problems may further lead to rework, re-finishing and even customer complaints.
Thus, in addition to providing stable functional effects, cold sense finishing agents should also minimize their impact on the original color of fabric as much as possible.
Finishing agent with lower yellowing and low shade changing is more suitable for white, light-colored fabrics and functional textile products with high requirements for color stability.
This is particularly important for dyeing mills to develop high-quality export orders, as functional products not only need to meet performance indicators but also maintain good appearance quality.
Why Does the Compatibility of Cold Sense Finishing Agents Affect Mass Production?
In actual production, dyeing mills usually do not just use one auxiliary chemical alone.
To achieve the ideal softness, color fastness, hydrophilicity or other functions, engineers may need to use cold sense son işlem maddesi together with silikon yağı ve sabitleme maddesivb.
Therefore, the compatibility of cold sense finishing agent will directly influence the process design.
If different auxiliaries are prone to precipitation, delamination or other unstable phenomena, it will increase the difficulty of working solution management and production adjustment, and even affect the appearance and function of the final fabric.
In contrast, products with good compatibility can be more easily integrated into the existing finishing system.
Especially nonionic cold sense finishing agents usually have good compatibility flexibility in practical applications, which can be formulated and combined with other finishing agents according to different fabrics and customer requirements.
Of course, the actual compatibility among different auxiliaries still needs to be tested according to specific products and production conditions, and cannot be judged merely by ion types.
Why Is Padding Process by Stentering Machine an Important Application Method for Cold Sense Finishing?
For most dyeing mills, stentering machines are important equipment in finishing production.
By evenly applying the cold sense finishing agent to the fabric surface through padding process, followed by drying and stentering, functional finishing can be integrated into the existing production process.
Compared with the finishing method that requires adding independent process, the padding process on stentering machine has the characteristics of high production efficiency, mature technology and convenience for continuous production.
For engineers, whether the cold sense finishing agent is suitable for padding process on stentering machine requires to pay more attention to the stability of working solution, product compatibility, evenness of the liquid on fabric, and the functional performance after heat treatment.
Especially in mass production, the effect of laboratory sample is only the first step. Products that have true commercial application value also need to maintain a stable cold sense effect, color performance and fabric quality during continuous production.
Cold Sense Finishing Brings New Product Value to Ordinary Fabrics
With the constantly increasing development of functional textile market, cold sense finishing is no longer merely a simple finishing technique, but has also become a way to upgrade the functions of ordinary fabrics.
By reasonable functional finishing, pamuk, polyester, nylon and other applicable fibers can be further used in summer clothing, sportswear, casual wear, beddings and other textile products that emphasize comfortable experience.
For textile enterprises, this method does not necessarily require mending the original fiber system, instead, it can imparts fabrics new functional selling points through finishing.
Of course, different fibers, fabric structures and production process have different responses to cold sense finishing agents. Therefore, in the actual production process, it is necessary to have small sample tests in combination with specific fabrics, and comprehensively judge the final finishing effect based on qmax, hydrophilicity, shade changing, handle and other customer indicators.
