Analysis on the practical effect of using polyurethane non-silicon silicone oil to enhance the softness and smoothness of textiles

The importance of softness and smoothness of textiles

In daily life, textiles are not only our basic needs for wear, but also an important reflection of our quality of life. Imagine wearing a rough texture and stiff feel, the discomfort is simply unbearable. Therefore, the softness and smoothness of textiles have become one of the key considerations when consumers choose clothing. Softness refers to the ability of fibers or fabrics to quickly return to their original state after being affected by external forces, while smoothness refers to the smoothness of the fabric surface. These two determine the feel and comfort of the textile.

From a historical perspective, human pursuit of softness and smoothness of textiles can be traced back to the ancient civilization period. As early as 3000 BC, people began to use vegetable oil to treat linens to improve their feel. With the advancement of science and technology, the modern textile industry has developed a variety of chemical processing technologies, among which polyurethane non-silicon silicone oil has attracted much attention for its excellent performance. This material not only can significantly improve the softness and smoothness of the textile, but also maintain the original breathability and hygroscopicity of the fabric, making it more comfortable to wear.

In today's market, consumers' requirements for textiles are increasing, and they are no longer satisfied with basic functionality, but pursue a higher comfort experience. This requires textile manufacturers to constantly explore new technologies and materials to meet market demand. Next, we will explore in-depth how polyurethane non-silicon silicone oil can effectively enhance the softness and smoothness of textiles through its unique chemical structure and physical properties, and analyze its application effects through actual cases.

The basic principles and unique advantages of polyurethane non-silicon silicone oil

As a new textile additive, polyurethane non-silicon silicone oil has its core charm lies in its unique design and versatility of its molecular structure. To understand why it can significantly improve the softness and smoothness of textiles, we need to understand its basic chemistry first. Simply put, polyurethane non-silicon silicone oil is a compound based on polyurethane. By introducing specific silicone-like groups, it gives it a special difference from traditional silicone oils and beyond ordinary polyurethanes. performance.

Chemical structure and functional characteristics

The core structure of polyurethane non-silicon silicone oil consists of two parts: one is the polyurethane backbone, and the other is the silicone group embedded in it. The polyurethane backbone provides good adhesion and film formation, and can form a uniform and firm protective film on the surface of the textile fibers; while the silicone groups impart excellent lubricity and flexibility to this film. This "two-pronged" design allows polyurethane non-silicon silicone oil to provide a smooth touch similar to traditional silicone oil, while avoiding problems caused by excessive dependence on silicone oil, such as yellowing, adhesions or environmental impacts.

Specifically, the working principle of polyurethane non-silicon silicone oil can be summarized as follows:

1. Film Forming Effect: When polyurethane non-silicon silicone oil is applied to the surface of a textile, its molecules will quickly diffuse and adsorb on the fibers, and then form a continuous film through cross-linking reaction. This film can not only effectively wrap the fibers, reduce friction between the fibers, but also enhance the elasticity of the fibers, thereby significantly improving the overall softness of the textiles.

2. Luction: The presence of silicone groups imparts excellent lubricating properties to polyurethane non-silicon silicone oil. These groups can form a low friction coefficient interface on the fiber surface, making the fabric smoother and more delicate to touch.

3. Durability and Environmental Protection: Compared with traditional silicone oil, polyurethane non-silicon silicone oil has higher washing resistance and stability. Even after multiple washes or mechanical wear, its effect can still last long. reserve. In addition, since it does not contain pure silicon components, polyurethane non-silicon silicone oil is more environmentally friendly and in line with the development trend of modern green chemical industry.

Comparison with other textile additives

To more intuitively demonstrate the advantages of polyurethane non-silicon silicone oil, we can compare it with other common textile additives. The following are several main types of textile softeners and their characteristics:

It can be seen from the table that although traditional silicone oil performs well in improving softness and smoothness, its durability and environmental protection are relatively poor; while polyetherester softeners are relatively environmentally friendly, Its performance is slightly inferior. In contrast, polyurethane non-silicon oilIt has achieved a perfect balance between performance and environmental protection, and is currently the leader in the field of textile additives.

Performance in practical applications

In practical applications, polyurethane non-silicon silicone oil has performed particularly well. For example, when dealing with cotton fabrics, it can effectively reduce the coefficient of friction between the fibers while maintaining the natural texture and breathability of the fabric. For synthetic fibers (such as polyester or nylon), polyurethane non-silicon silicone oil can significantly improve its surface roughness, making it more advanced and comfortable. More importantly, this material is suitable for all types of textiles, whether it is light shirt fabric or heavy jacket fabric, to show excellent results.

To sum up, polyurethane non-silicon silicone oil is gradually replacing traditional silicone oil and other softeners with its unique chemical structure and multiple advantages, becoming the new darling of the textile industry. Next, we will further explore its specific application cases in different textiles and how to choose the appropriate parameter configuration according to product needs.

Examples of application of polyurethane non-silicon silicone oil in various types of textiles

In the textile industry, the requirements for softness and smoothness of textiles of different types and uses vary. Polyurethane non-silicon silicone oil has become an ideal choice for many textile processing due to its wide range of adaptability and excellent properties. Below we use a few specific cases to analyze its application effects in different textiles in detail.

Application on cotton fabrics

Cotton fabrics are popular among consumers for their natural and comfortable properties, but untreated cotton fabrics often appear rougher. The application of polyurethane non-silicon silicone oil can significantly improve this problem. For example, when treating cotton cloth for T-shirts, after using a polyurethane non-silicon silicone oil solution with a concentration of 2%, the softness and smoothness of the cotton cloth are significantly improved. Experimental data show that the processed cotton cloth was reduced by 40% in the friction coefficient test and the hand feel score was improved by 3 levels.

Application on synthetic fibers

Synthetic fibers such as polyester and nylon are widely used in sportswear and outdoor equipment. These materials themselves are harder and lack the softness of natural fibers. These problems have been effectively solved by using polyurethane non-silicon silicone oil. Taking the waterproof nylon jacket produced by a certain brand as an example, after using a coating process containing 3% polyurethane non-silicon silicone oil, the surface of the jacket becomes smoother while maintaining good waterproof performance. User feedback shows that the comfort level of wearing has increased by more than 50%.

Application on wool fabrics

Wool fabrics are known for their warmth and nobleness, but their pilling and rough feel are common problems. The application of polyurethane non-silicon silicone oil on wool fabrics effectively solves these problems. A high-end cardigan manufacturer introduced a finishing solution containing 4% polyurethane non-silicon oil during its production process. The results show that the treated cardigan not only feels softer, but also has significantly enhanced its anti-pilling ability. Extended productLifespan.

Application on Silk Fabrics

Silk is known for its luster and smoothness, but being too smooth can lead to problems that are easy to wrinkle and difficult to clean. Polyurethane non-silicon silicone oil plays a regulating role here, allowing the silk fabric to maintain its original luster while increasing its moderate flexibility and wrinkle resistance. A silk manufacturer has adopted a post-tidying process containing 2.5% polyurethane non-silicon oil on its high-end scarf product line. Customer satisfaction surveys show that more than 90% of users believe that the quality of the new product is better than that of untreated products.

From the above cases, we can see that polyurethane non-silicon silicone oil has shown excellent performance in different types of textiles, which not only improves the softness and smoothness of the product, but also enhances the durability and user satisfaction of the product.

Scientific and rigorous approaches are crucial when evaluating the practical effect of polyurethane non-silicon silicone oils on textile softness and smoothness. Here we will introduce several commonly used technical indicators and experimental methods in detail, including friction coefficient measurement, hand feel scoring system, wash resistance testing and environmental protection assessment, to help readers better understand and evaluate the application effect of the material.

Friction coefficient measurement

The coefficient of friction is a key indicator for measuring the smoothness of textile surfaces. By using standard friction testers, we can accurately measure the coefficient of friction changes on textile surfaces before and after processing. For example, in an experiment on cotton fabrics, the untreated cotton fabric had a friction coefficient of 0.65, while the friction coefficient after treatment with polyurethane non-silicon oil dropped to 0.38, showing a significant improvement in smoothness.

Hand Scoring System

The hand feel scoring system is a subjective but effective evaluation tool that is usually scored by a group of professional reviewers based on specific criteria. The scoring criteria may include multiple dimensions such as softness, slipperiness, and thickness. In a case study on wool fabrics, the average score of wool sweaters treated with polyurethane non-silicon oil was 8.7 out of 10, which was much higher than the 6.2 points for untreated samples, which directly reflects a significant improvement in the feel of the product.

Washing resistance test

The wash resistance test was used to evaluate the durability of the treatment effect of polyurethane non-silicon oil. Typically, we put the treated textiles under standard washing conditions for multiple cycles and then measure their softness and smoothness again. In an experiment involving polyester fabrics, the polyurethane non-silicon oil-treated fabrics maintained more than 85% of the softness and smoothness of their initial state even after 20 standard wash procedures, demonstrating its excellent durability.

Environmental Assessment

Environmental protection assessment involves the safety and degradability of the material. Through laboratory analysis, weIt can be determined whether polyurethane non-silicon silicone oil meets international environmental standards. For example, several studies have shown that polyurethane non-silicon silicone oil performs better in terms of biodegradability and toxicity compared to traditional silicone oils, making it a more environmentally friendly option.

Comprehensive application of the above technical indicators and experimental methods can not only accurately evaluate the actual effect of polyurethane non-silicon silicone oil, but also provide a scientific basis for its further optimization and wide application. These data and conclusions provide valuable reference for textile manufacturers and consumers, ensuring they can make smarter choices.
