Characteristics of chemical fiber fabrics

Comfortability

In the early stages of development, chemical fiber had three major advantages: < /p>

First, it is strong and durable

Second, it is easy to care for and has anti-wrinkle and non-ironing properties

Third, it can be industrialized and mass-produced, unlike natural fibers. Land, processing is time-consuming and labor-intensive, and output is limited.

However, these traditional advantages of chemical fiber are no longer "scenery".

First, people nowadays pay attention to comfort and fashion when dressing. With the change of consumption concept, the durability of chemical fibers has become useless

Second, with the development of textile technology , natural fibers can still be easy to care for after finishing.

Third, people have realized that petroleum resources are non-renewable, and the chemical fiber industry that relies on petroleum resources will one day face "extinction" "Disaster.

When the traditional advantages are no longer popular, the weaknesses of chemical fibers such as poor hygroscopicity, poor comfort, and poor feel have become prominent. Therefore, starting from the comfort of natural fibers and using natural fibers as the "blueprint" to simulate and transform chemical fibers, it has become the driving force for the advancement of chemical fiber technology.

The most typical example is the advancement of polyester imitation silk technology. At the beginning, technicians imitated the triangular cross-section and fineness of real silk to make polyester yarn. The woven fabric produced aurora and was not like real silk. Therefore, by using matting agents and inventing the "alkali reduction method" to treat the surface of polyester silk, the polyester silk-like fabric looks very similar to real silk. Next, scientific and technical personnel used ultra-fine fiber technology to make the polyester imitation silk fabric feel the same as real silk. They also used plasma technology and laser technology to make the polyester fabric emit the same "silk sound" as real silk when rubbed. Voice". At this point, polyester imitation silk technology has finally reached a relatively complete level after several generations of evolution. However, scientific and technical personnel are not satisfied. Polyester silk-like technology has developed from simulation to super-real. Through the formation of grooves on the fiber surface, chemical fibers have better hygroscopicity than natural fibers; through the use of chemical grafting and polymerization methods, polyester can be The hygroscopicity of the fiber itself is increased hundreds of times, even exceeding that of natural fibers such as cotton and silk. As a result, a fabric that looks and feels exactly like silk, but is more comfortable, easy to care for, and dyed fresher than silk was created. In Japan, the price of kimonos made of super-simulated chemical fibers is much higher than that of real silk kimonos.

Functionality

In the long process of development, humans have found and actually utilized only a few or more than a dozen types of natural fibers. When mankind entered the era of chemical fibers, hundreds of new varieties of chemical fibers were invented in just a hundred years.

As a man-made polymer, chemical fiber can be pre-designed for functionality during the production process. For example, adding antibacterial agents makes it have antibacterial function; adding mineral micropowder makes it have low radiation function or far infrared radiation function. This is obviously easier, more economical and more effective than modifying natural fibers.

In addition to being able to more easily give new functions to chemical fibers in design and production, the properties and characteristics of the polymers that make up the chemical fibers themselves also have functional factors. For example, the macromolecular structure of acrylic fiber is very stable and has the ability to withstand ultraviolet radiation. In addition, acrylic fiber is dyed with cations, which not only has bright colors, but also has extremely high light fastness. Therefore, people use acrylic fiber fabrics as sunshade products. Its functionality and practicality are fully utilized.

Similarly, the wear resistance of nylon makes it widely used in sportswear, the high strength of para-aramid makes it used in bulletproof clothing, and the high-temperature resistance of chlorine fiber and meta-para-aramid makes them It is widely used as flame retardant products.

High sensitivity: the personalized direction of chemical fiber

Fundamentally speaking, natural fiber is the product of natural selection, so it has a comprehensive nature. That is to say, if we comprehensively evaluate all aspects of a fiber, no chemical fiber can compare with natural fiber. However, from the evaluation of local indicators, the performance of many chemical fiber varieties exceeds that of natural fiber.

As people’s living standards improve, the consumption requirements for textiles are also changing. The wearing comfort often mentioned in the industry is a combination of a series of specific technical indicators.

For example, touch includes the softness, drape, pressure contact, hot contact, cold contact, etc. of textiles. With the development of textile material science, the requirements for the technical indicators of fibers are becoming more and more detailed. For example, those related to fiber strength include elastic modulus, acute elastic deformation, slow elastic deformation, tensile strength, shear strength, tensile strength, etc. Strength and a series of technical indicators. It was discovered during the study that if the molecular weight, degree of polymerization, degree of orientation, as well as the fineness, cross-sectional shape and length of the chemical fiber are changed, the physical and chemical properties of the fiber can be changed. Therefore, the so-called differentiated chemical fiber stands out and becomes the development direction of chemical fiber.

In response to the changes in the textile consumer market, the Japanese textile industry refers to differentiated fibers as highly sensitive fibers. In fact, it is the design and production of a series of chemical fibers with outstanding local advantages, and then through modern textile processing technology, the properties of different chemical fibers can be complemented by each other, and a variety of textiles can be produced that have comprehensive properties that exceed those of natural fibers. The development direction of Japan's chemical fiber industry has been recognized by consumers around the world, so the differentiation rate of Japanese chemical fiber products has already reached over 40%.

Advantages and Disadvantages of Chemical Fiber Fabrics

Advantages of Chemical Fiber Fabrics

In China, probably no one agrees that chemical fiber fabrics are better than natural fiber fabrics. But in developed countries, the view is exactly the opposite: most consumers believe that chemical fiber fabrics have more superior functions in terms of comfort, functionality, and high rationality.

Comfort: Chemical fiber has three major advantages in the early stages of development: first, it is strong and durable; second, it is easy to care for, has anti-wrinkle and non-iron properties; third, it can be industrialized and mass-produced, unlike natural fibers. Fiber takes up land, processing is time-consuming and laborious, and output is limited.

Functionality: As an artificial high molecular polymer, chemical fiber can have its functionality planned in advance during the production process. For example, adding antibacterial agents makes it have antibacterial function; adding mineral micropowder makes it have low radiation function or far infrared radiation function. This is obviously simpler and more economical than modifying natural fibers, and the effect is more obvious.

High rationality: Regarding the changes in the textile consumer market, the Japanese textile industry refers to differentiated fibers as highly rational fibers. In fact, it is the planning and production of serialized chemical fibers with outstanding advantages in certain areas. Then through modern textile processing technology, the functions of different chemical fibers can be combined to complement each other, and a wide range of textiles with comprehensive functions superior to natural fibers can be produced. The development direction of Japan's chemical fiber industry has been recognized by consumers internationally, so the differentiation rate of Japanese chemical fiber products has already reached over 40%.

Disadvantages of chemical fiber fabrics

1. Chemical fiber fabrics have poor wear resistance, heat resistance, hygroscopicity and air permeability. They are easily deformed when exposed to heat and generate static electricity. They are prone to long-term use. Harmful to human body.

2. Chemical fiber fabrics have poor adsorption properties and cannot "adsorb" to silk well. Since silk cannot be integrated with the tire cover, after a period of use, the silk will shrink into a ball, affecting the use effect.

So, why do some businesses like to use chemical fiber fabrics as silk quilt fabrics? This is because:

1. The cost of chemical fiber fabrics is low, preferably only a few yuan per meter. Even the price of the most common cotton cloth is inferior.

2. Chemical fiber fabrics can be made into silk-like effects, which can easily lead some customers to mistakenly think "real silk" and spend their money.

Monthly Summary of Polyester FDY Chemical Fiber Factory

As the New Year approaches, the new year is about to begin. In this wonderful season of new beginnings and renewal of everything, the work in my workshop in January has come to an end. Looking back on the work content in January, the workshop implemented various production management tasks one by one according to the plan and strictly implemented the company's management requirements. The specific work summary in January is as follows:

1. Communicate and organize employees to carefully study the company's year-end summary report. All work sections and teams are required to study the content of the meeting carefully and implement it in their work. In particular, we must work closely around the "two improvements, two guarantees, and two reductions" proposed by the chairman. At the same time, based on the current situation of our workshop and combined with the work requirements put forward in the general manager's report, the workshop made detailed plans for important tasks such as spindle management, inspection of key equipment, market segmentation, adjustment of the four management activities and assessment content.

2. Ensure the quality of product market segmentation work and steadily improve the quality of products in the entire workshop. The workshop thoroughly cleans the side blowing stencils and drawer stencils of each spindle and replaces them with non-woven fabrics. In addition, in response to the 61/24 quality problem, the workshop conducted testing and tracking on 87 spindle positions for the production of this variety, including: tracking the dyeing status of all stockings at the spinning position; and making test records of the side blowing conditions and the temperature of the hot roller. In good condition. The spindle line numbers where the customer reported quality issues were actually F5 and 6 lines, so the above inspections and tests were also conducted on the 18 spindle positions of these two lines.

3. On January 15, the raw material for chip spinning was changed from Yizheng chips to Liaohua Kunlun chips. The product batch number was changed from R-07 to R-08. The workshop conducts isolation work before and after material change. The excessive silk is made in a separate batch number R-100, and the color of the paper tube is snow-green.

4. On January 16, Mingyang switched filters. After replacing the filter, the number of wool filaments and broken ends increased significantly, the fixed length rate decreased, the consumption increased, and the production status dropped sharply. The main reason is that the filter Mingyang replaced this time has been used too many times. At 9:30 a.m. on the 21st, the filter was replaced again, and now production is gradually returning to normal. In addition, on the 27th, Mingyang's evaporator failed and the vacuum system fluctuated, which had a certain impact on production.

5. Organize and arrange the teams in each section to do pre-holiday sanitation cleaning work.

6. Do a good job in registering smoking employees in the workshop. After the fifteenth day of the first lunar month, anyone found carrying cigarettes or smoking will be fined 5,000 to 10,000 yuan.

7. Organize regular workshop meetings and conduct publicity and division of labor for the four activities. In addition, in response to the problem of poor mental state of spinners, the workshop held a separate meeting to emphasize the issue and required each operation squad leader to strengthen management work. At the same time, the workshop increased the compensation and deduction for managers.

8. In order to further strengthen spindle position management, stabilize production, process continuous wool and other quality spindles, and improve various production indicators, in addition to weekly spot checks in the workshop, the workshop also conducts large-scale spot checks on spindle positions. Arrange workshop cadres to implement the lump sum system and conduct daily spindle inspections.

9. Organize workshop management cadres to inspect and accept the pre-holiday sanitation work in the entire workshop. Correct existing problems immediately and arrange for another review.

In February, we will continue to conscientiously implement and implement various company management requirements. Steadyly improve various production data, strengthen various management tasks in the workshop, and conduct production management in an orderly manner according to the detailed plans formulated by the workshop. The specific work plan is as follows:

1. During the festival, we must do a good job in all production management links to ensure stable production and complete various production indicators.

2. Strengthen four basic management tasks. In particular, we will strengthen self-examination in workshops to prevent production accidents.

3. Modify the assessment plan and implement waste silk measurement assessment.

4. Intensify efforts to inspect and deal with disciplinary violations such as late arrival and early departure, smoking, sleeping on duty and other employees. In addition, employees are required not to bring snacks and sundries into the workplace.

5. Pay close attention to the attendance system to prevent employees from taking turns taking turns to ensure the number of people on the job and ensure normal production.

6. The outer iron sheet of the outdoor melt transportation pipeline between the workshop and Mingyang has rotted for many years, and a new rain shelter needs to be built. Prepare to start this work after the beginning of the new year.

7. Strengthen product quality self-examination, self-inspection and random inspection. Prevent quality accidents and prevent substandard products from flowing into the hands of customers.
