How are textile fibers classified?

Fibre soft and slender substance with length to diameter ratio at least 10:1,  the cross-sectional area less than 0.05mm2. For textile fibers, the ratio of length to diameter is generally greater than 1000:1. 

About textile fibers: Natural fiber, such as cotton, hemp, wool, silk and so on; Chemical fiber refers to natural or synthetic polymers as raw materials, through chemical methods and mechanical processing made as fiber.

 

1) According to the source of raw material: Regenerated fibre and Synthetic fibres

  • Regenerated fibre also be called as synthetic fiber, using natural polymers or lost textile processing value of fiber raw materials through a series of chemical treatment and mechanical processing be fiber again, the chemical composition of the fiber and original polymer is alomost same. Including Regenerated cellulose fibre (such as viscose fiber, copper ammonia fiber), Regenerated protein fiber  (such as soy protein fiber, peanut protein fiber), regenerated inorganic fiber (such as glass fiber, metal fiber)  and regenerated organic fiber (such as chitin fiber, seaweed gum fiber).
  • Synthetic fiber is made of natural low molecular compounds such as petroleum, coal, limestone, natural gas, salt, air, water and some agricultural and sideline products as raw materials, through chemical synthesis and processing be fibers. There are seven common types of synthetic fibers: polyester fiber (polyester), polyamide fiber (nylon), polyacrylonitrile fiber (acrylic fiber), polyvinyl formaldehyde fiber (vinylon), polypropylene fiber (polypropylene), polyvinyl chloride fiber (chlorinated fiber) and polyurethane elastic fiber (spandex), etc. 

     

     

    2) Classification by morphological structure: Continuous filament and Staple fibre

    • Continuous filament 

      During chemical fiber manufacturing process, spinning fluid (fusant or melt) after spinning forming and post-processing, the length of fiber is caiculated in kilometers is called chemical fiber filament. Chemical fiber filaments can be divided into monofil, multifilaments, twisted fibers, double twisted fibers, cord fibers and Textured filament.

      Monofilament: A single continuous fiber of very long length.

      Multifilaments: A filament composed of two or more single filaments joined together. Complex filaments of chemical fibers are generally composed of 8 to 100 single fibers.

      Twist yarn: twist Multifilaments  becomes twist yarn.

      Double twist yarn: Two or more strands of twist yarn are combined to be double twist yarn.

      Cord wire: composed of more than one hundred to several hundred single fibers, used to make tire cord fabric.

      Textured filament yarn: The chemical fiber filament is deformed and processed so that it has the appearance characteristics of curling, spiral, ring and so on, showing fluffy and flexible filament.

      • Staple fibre

        The product of the chemical fiber is cut into few centimeters to dozen centimeters in length, it is called staple fiber. According to the different cut length, staple fibers can be divided into cotton type, wool type and medium long staple fibers.

        The length of Cotton type fibre is 30 ~ 40mm, the linear density is about 1.67dtex, the fiber is fine, similar to cotton. The length of Wool type fibre is 70 ~ 150mm, the linear density is 3.3 ~ 7.7dtex, the fiber is thicker, similar to wool; Mid fibre has a length of 51 ~ 65mm and a linear density of 2.2 ~ 3.3dtex, between cotton type and wool type.

         

        3)  Classification by fiber manufacturing method

        Chemical fibers can be divided into two categories according to the basic manufacturing methods,  melt spinning fibers and solution spinning fibers (i.e. dry spinning fibers and wet spinning fibers).

        • Melt spinning is polymer melt is pressed out of the spinneret hole, melt is solidified into silk in the surrounding air (or water).
        • Dry-spinning is polymer concentrated solution is pressed out from the spinneret hole form as trickle, solvent evaporates rapidly in hot medium and solidifies into silk. 
        • Wet spinning is polymer concentrated solution is pressed out of the spinneret hole and solidified into silk in a coagulation bath.

           

          4) Classification by composition within a single fiber

          • Single-component fibers: Fibers composed of the same polymer are called single-component fibers, and most conventional fibers are single-component fibers, such as polyester.
          • Multicomponent fibers:Fibers composed of two or more polymers are called multicomponent fibers, such as acrylic fibers. 
          • Composite fiber:the components are arranged regularly along the fiber axis and form a continuous interface fiber.
          • Blended fiber: components are randomly dispersed or more evenly mixed fiber

             

            5) Classification by fiber difference

How many kinds of functional knitting products?

Knitting products are widely used in the three major fields of wear, decoration and industrial use, forming a relatively complete knitting industry chain. Functional knitting products include sports apparel, medical assistance products, military defense supplies & fashion apparel developed through the integration of high-tech material with knitting technology, which not only meet the increasingly diverse needs of people,but also innovate in combination with cutting-edge technology. With the rapid development of science and technology,various functional & diversified products combining traditional textile technology emerge in endless stream. According characteristics of knitted fabrics, functional knitting products, as an important product combining textile technology and scientific innovation, are gradually becoming new focus of the development of the textile industry. At the same time,with the development of green functional knitting products, functional knitwear is not only the result of technological innovation, but also embodiment of market demand and sustainable development trends.

1. Hygroscopic and perspiratory knitted products

The wetting process of sweat involves the contact and penetration between sweat and fiber and fabric surface. The water in this process mainly depends on the capillary action between fiber and yarn to move, and the water finally evaporates rapidly through the fabric surface to achieve the quick-drying effect. Moisture wicking fabric can effectively reduce the retention time of sweat on the skin surface, keep the skin dry and reduce the growth of bacteria, improve the wearer's comfort. Related applications in sports products include cycling clothing, yoga clothing, sports underwear, sports shoes, etc.

 

2. Antibacterial knitting products

Antibacterial knitted fabrics can realize antibacterial function through five ways: natural antibacterial fiber, regenerative antibacterial fiber, synthetic antibacterial fiber, modified antibacterial fiber and antibacterial agent finishing and processing. On this basis, combined with organizational structure design, product performance can be further optimized and bacterial growth can be effectively inhibited. At present, antibacterial knitting products are used in daily use, medicine and other fields.

 

3. Uv protection knitted products

Uv protection can be achieved through functional yarns or functional finishing (sunscreen reagents, functional coatings). Anti-ultraviolet function products can effectively block ultraviolet radiation, make the wearer feel more comfortable, extend the service life of the product, in outdoor, use, automotive materials and other fields have been developed and applied.

 

4. Waterproof knitting products

Waterproof knitted products are made by functional yarn or special finishing technology, which can effectively prevent water from penetrating into the interior of knitted products, prevent stains, fading and fabric deformation caused by water, and improve the durability and quality stability of products. At present, waterproof functional knitting products are used in outdoor sports, daily protection and other fields.

 

5. Electromagnetic shielding knitting products

Electromagnetic shielding knitting products are used in daily use, military defense and other scenarios. Electromagnetic shielding fabric is an excellent shielding material made of functional yarn with both light weight, flexibility and strength. It is widely used because of its thin and light, good surface adhesion and a large number of grid structures. At present, the design principle of electromagnetic shielding fabrics is mainly to use the conductivity of the material to metalize the surface of the fabric to form a metal conductive layer, or to make conductive filament and conductive yarn first, and then weave into the fabric, so that the metal conductive grid is formed inside the fabric.

 

6, Smart responsive knitting products

Intelligent response technology provides more possibilities for the development of functional knitting products, in addition to the traditional clothing field, intelligent response knitting products can also be applied to medical, sports, military and other fields. Through intelligent components, knitting products can achieve a variety of functions such as health monitoring, position tracking, and temperature regulation.

 

7. Warm knitting products

Warm knitting products can be used to form a static air layer inside the fabric through the selection of functional fibers or yarns with warmth, combined with the tissue design, to reduce heat loss, and can also be adjusted by the weaving process parameters (such as density, thickness, etc.) to improve the thermal performance of the fabric. A wide range of warm knit products, including warm underwear, warm coats, warm knee pads and so on. The composite fiber prepared by special process not only makes up for some performance shortcomings of natural fiber, but also shows superior thermal performance. The knitted products prepared by it can also have other properties, such as antibacterial, antistatic, breathable and so on, while having warmth.

 

8. Stab-proof and cut-proof knitting products

Stab-proof and cut-proof products are widely used in military, medical, sports and other fields, including anti-cut neck guard, stab-proof clothing, stab-proof vest, cut-proof gloves and other products. Among them, flexible stab-proof clothing can not only meet the requirements of special occupations for protective performance, but also suitable for daily wear because of its comfort, which is a research hotspot in recent years. Bulletproof textiles made from high-strength fibers such as ultra-high molecular weight polyethylene (UHMWPE) or aramid provide some protection against projectiles such as shrapnel and ammunition fragments. The traditional full overlay design limits the energy absorption of the composite during ballistic impact. In contrast, the checkerboard design formed by polycarbonate (PC) film and aramid can effectively improve the ballistic performance. The bullet-proof performance of the checkerboard PC film also increases with the increase of the number of spacer layers.

 

9. Other functional knitting products

Other functional knitting products also include fire retardant, anti-static, anti-mosquito and other products.

Why the choice of dyeing machine crucial to the quality of dyed products?

There are numerous factors that influence the quality of dyed products, chief among them being equipment, dyes and chemicals, processes (procedures, formulations, conditions)  and operational factors. Occasionally, defects in dyeing can also arise due to chance occurrences. Therefore, when analyzing the root causes of quality issues, it's imperative to consider all aspects thoroughly to pinpoint the actual cause, allowing for resolution and prevention of recurring issues. According experience, product quality control measures can be implemented.

 

In this context, let's delve primarily into the impact of dyeing equipment on the quality of dyed products.

 

To achieve superior dyed products, not only must suitable dyes be selected based on the type of fiber and fabric, but also must appropriate textile dyeing machine be paired with customized and rational dyeing processes. Despite advancements in production technology and the continuous improvement of dyeing machinery, quality issues stemming from equipment are still not entirely avoidable.

fabric

The primary concern related to yarn dyeing machine and fabric dyeing machine is its operational stability, efactors such as machine speed, drying condition, temperature ramp-up and ramp-down rate, and pressure control. When these parameters are tightly controlled, the dyeing and finishing machinery can ensure consistent color reproduction and reproducibility.

 

Textile dyeing machine pivotal role in achieving even dyeing. To this end, the following requirements are crucial:

 

1. **Strong Dyeing Process Adaptability**: dyeing machine must be capable of accommodating a wide range of process parameters like temperature, pressure, speed, and treatment time, as well as adjustment to dyestuff and chemical, ensuring compatibility with new processes and technologies. This ensures uniform dyeing and meets other quality standards.

 

2. **High Automation Level**: Automated detection and adjustment of key process parameters minimize human errors, enhancing precision control. This ensures the repeatability of processes and stabilizes product quality.

 

3. **Versatility for Multi Processing**: Given the limited resources in dyeing plant and ever-changing market demands,  fabric and yarn dyeing equipment should be versatile, allowing for cost-effective processing of various fabric and yarn types while maintaining dyeing uniformity and meeting other quality criteria.

 

4. **Low-Tension or Loose Running**: Tension is a significant factor affecting dyeing evenness. High or uneven tension can easily lead to quality issues. Hence, dyeing equipment should operate with minimal or uniform tension, preferably in a loose-running mode. It is related with the design of dyeing machine structure.

In addition to the processes and operations defined, the color matching and dyeing levelness of products are intimately tied to the dyeing equipment chosen. The selected equipment must cater to the requirements of various dyeing processes, handle diverse product types, produce high-quality outputs, and be safe, durable, economical, high-speed, efficient, continuous, automated, low-energy consuming and environmentally friendly. In essence, the equipment must guarantee the quality of dyed product.
