Is chemical fiber fabric harmful to human body?
Chemical fiber fabrics are harmful to human body. Chemical fiber fabrics are harmful to human body. Anyone who has bought chemical fiber fabrics knows that chemical fiber fabrics are easy to generate static electricity when worn, such as cotton fibers. The static electricity carried is relatively strong, which may cause functional heart rate imbalance, which is not good for health. In addition, chemical fiber fabrics are allergic to some skin, which is more irritating to children.

Polyester fabric is a kind of chemical fiber clothing fabric widely used in daily life. Its biggest advantage is good wrinkle resistance and shape retention, and it is suitable for making outerwear clothing. Polyester fabric has the following characteristics. Polyester fabric has high strength and strong elastic recovery ability, so it is durable, wrinkle-resistant and non-ironing.
Polyester fabric has poor hygroscopicity. Wearing it feels sultry, but it is also easy to carry static electricity and pollute dust. Affect aesthetics and comfort. However, it is very easy to dry after washing, and the wet strength hardly decreases, and it does not deform, so it has good washing resistance and wear resistance.
Which fabric is better, chemical fiber or polyester?
Compared with polyester fabric, chemical fiber fabric is superior to polyester fabric. It's more crisp and less wrinkled. It may look more advanced, mainly depending on personal preferences.
Is the chemical fiber fabric good
As a new type of fabric developed in modern times, chemical fiber fabric has a wide variety and has been widely used in clothing, curtains, home accessories and many other fields. The quality of chemical fiber fabric is determined by the characteristics of chemical fibers woven into it. Let's look at the price of chemical fiber fabrics.
What is chemical fiber fabric?
Chemical fiber fabric is a fabric made of pure chemical fibers, which is spun, blended or interwoven. Fabrics blended or interwoven with natural fibers do not belong to chemical fiber fabrics. There are many kinds, mainly tiger kapok, strong rayon, polyester, nylon, acrylic, polyvinyl chloride, vinylon, spandex and so on.
Is the chemical fiber fabric good
At home, most people think that chemical fiber fabrics are not as good as natural fiber fabrics, while abroad, most consumers think that chemical fiber fabrics are more comfortable, functional and sensitive. However, the reality is that chemical fiber fabrics use modern high technology, from simulation to surrealism, and constantly show new advantages, which are widely used in clothing, home accessories, daily necessities and other fields.
1.
Polyester has the same appearance and feel as natural fiber, and even its comfort, easy beating and dyeing freshness have surpassed natural fiber. Therefore, the price of some advanced chemical fiber fabrics has exceeded that of natural fibers.
2.
The function of chemical fiber fabric is superior. Adding antibacterial agent to chemical fiber fabric can increase its antibacterial function. Mineral micropowder is added to make it have low radiation function or far infrared radiation function. In addition, many chemical fiber fabrics also have the functions of ultraviolet protection, wear resistance and high temperature resistance.
3.
Chemical fiber fabrics are more personalized. Through modern textile processing technology, we can learn from each other's strong points and produce all kinds of textiles with comprehensive properties exceeding natural fibers. Such as the production of flame retardant fiber, high temperature resistant fiber, elastomer fiber, etc.
The price of chemical fiber fabric
Chemical fiber fabrics have different prices because of their different scientific and technological contents, characteristics, grades, functions and types. The following is the approximate price of chemical fiber fabrics. The prices of polyester fabrics range from 4 yuan to 74 yuan, spandex fabrics from 8 yuan to 60 yuan, and acrylic fabrics from 12 yuan to 85 yuan.
After reading my introduction, do you have a deeper understanding of chemical fiber fabrics? Are you good at chemical fiber fabrics? You must already know the price of chemical fiber fabrics. Nowadays, chemical fiber fabrics are everywhere in our lives. Pay attention to the fabric around us and see what kind of chemical fiber fabric it contains.

summary
Chemical fiber fabrics are harmful to human body. If you wear underwear with chemical fiber fabric for a long time, it will lead to microbial reproduction and corruption, and induce allergies and eczema. A large number of trace chemical elements are mixed in the production process of synthetic fibers, which will do great harm to people with skin allergies.
Characteristics of chemical fiber
In our country, I'm afraid no one agrees that the performance of chemical fiber fabrics is better than that of natural fiber fabrics. But in developed countries, the view is just the opposite: most consumers think that chemical fiber fabrics are superior in comfort, functionality and high sensitivity.
Characteristics, advantages and disadvantages of chemical fiber fabrics
Characteristics, advantages and disadvantages of chemical fiber fabrics
Characteristics of chemical fiber fabric
comfortable
Chemical fiber has three advantages in the early stage of development:
First, it is strong and durable.
Second, it is easy to take care of and has the characteristics of wrinkle resistance and no ironing.
Third, industrial mass production can be carried out, unlike natural fibers, which occupy land, processing is time-consuming and laborious, and the output is limited.
But these traditional advantages of chemical fiber are no longer "scenery".
First of all, people now pay attention to comfort and fashion in their clothes. With the change of consumption concept, the durability of chemical fiber becomes useless.
Secondly, with the development of textile technology, natural fibers can be easily treated after finishing.
Third, people have realized that oil resources are non-renewable, and the chemical fiber industry developed by relying on oil resources will face the disaster of "extinction" one day.
When the traditional advantages are gone, the weaknesses of chemical fiber such as poor hygroscopicity, poor comfort and poor hand feel are highlighted. Therefore, starting from the comfort of natural fiber and taking natural fiber as the "blueprint", the simulation transformation of chemical fiber has become the driving force to promote the technological progress of chemical fiber.
The most typical example is the progress of polyester silk-like technology. At the beginning, technicians imitated the triangular section and fineness of silk to make polyester yarn, and the woven fabric was not like silk because of aurora. Therefore, by using matting agent, the "alkali deweighting method" was invented to treat the surface of polyester silk, which made the polyester silk-like fabric very similar to real silk in appearance. Then, by using superfine fiber technology, technicians make silk-like polyester fabric have the same feel as real silk, and by using plasma technology and laser technology, polyester fabric can also make the same "silk sound" as real silk when rubbing. At this point, after several generations of evolution, polyester silk-like technology has finally reached a relatively perfect level. However, scientists and technicians are not satisfied. Polyester silk-like technology has developed from simulation to surrealism. By forming grooves on the fiber surface, the hygroscopicity of chemical fiber is better than that of natural fiber. Through chemical graft polymerization, the hygroscopicity of polyester fiber itself has been improved by hundreds of times, even exceeding natural fibers such as cotton and silk. In this way, the appearance and feel are exactly the same as those of real silk, but the comfort, easy beating and dyeing freshness are higher than those of real silk fabrics. In Japan, the kimono made of super-simulated chemical fiber is much more expensive than the silk kimono.
function
In the long process of human development, only dozens of natural fibers have been discovered and really utilized. Mankind has entered the era of chemical fiber, and hundreds of new varieties of chemical fiber have been invented in just a hundred years.
As an artificial polymer, chemical fiber can be designed in advance in the production process. For example, adding antibacterial agent to make it have antibacterial function; Mineral micropowder is added to make it have low radiation function or far infrared radiation function. This is obviously easier, more economical and more effective than transforming natural fibers.
In addition to endowing chemical fiber with new functions in design and production, the characteristics and characteristics of polymers that constitute chemical fiber itself also have functional factors. For example, the macromolecular structure of acrylic fiber is very stable and has the ability to resist ultraviolet rays. In addition, acrylic fiber dyed with cation not only has bright color, but also has high light fastness. Therefore, people use acrylic fabric as a sunshade product, and its functionality and practicality are fully exerted.
Similarly, the abrasion resistance of nylon makes it widely used in sportswear, the high strength of para-aramid makes it widely used in bulletproof vests, and the high temperature resistance of chlorine fiber and meta-aramid makes it widely used in flame retardant products.
High sensitivity: the personalized direction of chemical fiber
Fundamentally speaking, natural fiber is the product of natural selection, so it has all-encompassing properties. That is to say, from the comprehensive evaluation of a fiber, no chemical fiber can be compared with natural fiber, but from the local indicators, the performance of many chemical fiber varieties exceeds natural fiber.
With the improvement of people's living standards, the consumption requirements for textiles are also changing. Comfort is a combination of a series of specific technical indicators. For example, the sense of touch includes softness, drape, pressure contact, hot contact and cold contact of textiles. With the development of textile materials science, the requirements for fiber technical indicators are becoming more and more detailed, such as elastic modulus, acute elastic deformation, slow elastic deformation, tensile strength, shear strength, tensile strength and a series of technical indicators related to fiber strength. It is found that if the molecular weight, degree of polymerization and orientation of chemical fibers are changed, as well as the size, cross-sectional shape and length of chemical fibers, the physical and chemical properties of the fibers can be changed, so the so-called differentiated chemical fibers will stand out and become the development direction of chemical fibers.
In view of the changes in the textile consumer market, the Japanese textile industry calls differentiated fibers high-sensitivity fibers. In fact, it is to design and produce a series of chemical fibers with outstanding advantages in some fields, and then through modern textile processing technology, the performance of different chemical fibers will learn from each other's strong points to produce various textiles with comprehensive performance exceeding that of natural fibers. The development direction of Japanese chemical fiber industry has been recognized by consumers all over the world, so the differentiation rate of Japanese chemical fiber products has already reached more than 40%.
Advantages and disadvantages of chemical fiber fabric
Advantages of chemical fiber fabrics
In China, I'm afraid no one agrees that the function of chemical fiber cloth is better than that of natural fiber cloth. But in developed countries, the concept is just the opposite: most consumers think that chemical fiber fabrics are superior in comfort, functionality and high rationality.
Comfort: chemical fiber has three advantages in the early stage of development: first, it is firm and practical; Second, it is easy to take care of and has the characteristics of anti-wrinkle and non-ironing; Third, it can be industrialized and produced on a large scale, unlike natural fibers, which occupy land, processing is time-consuming and laborious, and the output is limited.
Functionality: As an artificial polymer, chemical fiber can be planned in advance in the production process. For example, adding antibacterial agent to make it have antibacterial function; Mineral micropowder is added to make it have low radiation function or far infrared radiation function. This is obviously simpler, more economical and more effective than transforming natural fibers.
High rationality: In view of the changes in the textile consumption market, the Japanese textile industry calls differentiated fibers high rationality fibers. In fact, it is planning to produce a series of chemical fibers with outstanding advantages in some parts, and then through modern textile processing technology, the functions of different chemical fibers will complement each other to produce textiles with various inductive functions beyond natural fibers. The development direction of Japanese chemical fiber industry has been recognized by international consumers, so the differentiation rate of Japanese chemical fiber products has already reached more than 40%.
Disadvantages of chemical fiber fabric
1, chemical fiber fabrics have poor wear resistance, heat resistance, hygroscopicity and air permeability, and are easy to deform and generate static electricity when heated, which is harmful to human body after long-term use.
2. The chemical fiber fabric has poor adsorbability and can't "adsorb" silk well. Because silk can't be integrated with the tire cover, it will shrink into a ball after being used for a period of time, which will affect the use effect.
Then, why do some merchants like to use chemical fiber fabrics as silk quilt fabrics? This is because:
1, the cost of chemical fiber fabric is low, preferably only a few yuan a meter, which is not even as good as the price of the most common cotton cloth.
2. Chemical fiber fabrics can be made into silk-like effects, and it is easy for some customers to mistake it for "real silk" and pay the bill.

Monthly summary of polyester in FDY chemical fiber factory
With the approach of the new year, the new year is about to begin. At the beginning of the new year, in the beautiful season of Vientiane renewal, the work of our workshop in June 5438+10 has come to an end. Looking back on the work of 5438+ 10 in June, the workshop carried out various production management work one by one according to the plan and strictly implemented the management requirements of the company. The specific work of 5438+ 10 is summarized as follows:
1. Communicate and organize employees to seriously study the company's year-end summary report. All sections and teams are required to seriously study the contents of the meeting and truly implement it in their work. In particular, we should work closely around the "two proposals, two guarantees and two reductions" put forward by the chairman. At the same time, according to the current situation of our workshop and the work requirements put forward in the general manager's report, the workshop has made a detailed plan for spindle position management, key equipment inspection, market segmentation, adjustment and assessment of four management activities.
2. Ensure the quality of product market segmentation and steadily improve the product quality of the whole workshop. The workshop thoroughly cleaned the side blowing screen and drawer screen of each spindle and replaced the non-woven fabric. In addition, in view of the quality problem of 6 1/24, the workshop has detected and tracked 87 ingots producing this variety, including: all ingots fall off silk and follow up the dyeing situation; Test and record the temperature of side blower and hot roller. In good condition. The customer's spindle line numbers reflecting quality problems are actually F5 and 6 lines, so the above inspection and test are also carried out for the 18 spindles of these two lines.
No.3.65438+10/Oct.65438 +05, the raw material of chip spinning was changed from Yizheng chip to Liao Hua Kunlun chip. The product batch number was changed from R-07 to R-08. Before and after refueling, the workshop should be isolated. Excess silk should be made separately with the batch number of R- 100, and the color of paper tube should be snow blue.
On June 65438+10/October 65438+June 6, Yang Ming changed the filter. After replacing the filter, the hairiness and broken ends increased obviously, the fixed length rate decreased, the consumption increased and the production situation decreased sharply. The main reason is that the filter replaced by Yang Ming has been used too many times. 2 1 The filter was changed again at 9: 30 am, and now the production is gradually returning to normal. In addition, on the 27th, Yangming evaporator failed and the vacuum pump system fluctuated, which had a certain impact on production.
5, organize and arrange each section team to do a good job of cleaning up before the festival.
6. Do a good job in the registration of smoking employees in the workshop. After the fifteenth day of the first month, anyone who finds cigarettes and smokers on his body will be given a treatment of 5000 to 10000 yuan.
7. Organize workshop meetings on a regular basis to publicize and divide the four activities. In addition, in view of the poor mental state of the spinners, the workshop held a separate meeting to make an important emphasis, requiring the operation squad leaders to strengthen management, and at the same time, the workshop increased the salary of managers.
8. In order to further strengthen spindle management, stabilize production, handle high-quality spindles such as continuous wool and improve various production indicators, the workshop conducts spot checks on spindles every week, arranges workshop cadres to implement contract system, and conducts spindle inspection every day.
9. Organize workshop management cadres to check and accept the pre-holiday health work of the whole workshop. Immediately correct the existing problems and arrange the second review.
In February, we will, as always, earnestly implement the requirements of corporate governance. Steadily improve production data, strengthen workshop management, and conduct production management in an orderly manner according to the detailed plan formulated by the workshop. The specific work plan is as follows:
1, during the festival, special attention will be paid to various production management links to ensure stable production and achieve various production indicators.
2, strengthen the four basic management work. In particular, strengthen the self-inspection work in the workshop to prevent production accidents.
3, modify the assessment plan, the implementation of waste silk measurement assessment.
4. Strengthen the inspection of employees who are late and leave early, smoking, sleeping on duty and other disciplinary phenomena, and deal with them seriously. In addition, employees are also required not to bring snacks and sundries into their posts.
5, pay close attention to the attendance system, put an end to the chaotic rotation of employees, ensure the number of people on the job, and ensure the normal production.
6. The outer iron sheet of the outdoor melt conveying pipeline between the workshop and Yang Ming has rotted for many years, so it is necessary to build a rain shelter again. Prepare to start this work after the new year.
7. Strengthen product quality self-inspection, self-inspection and sampling inspection. Prevent quality accidents and prevent unqualified products from flowing into customers' hands.
