Acrylic, known as "Orlon" in the United States and "Acrilan" or "Cashmilon" in other countries, it is the commercial name for polyacrylonitrile in China. It's one of three major types of synthetic fiber, ranking third in production after polyester and nylon. Soft, lightweight, warm, corrosion-resistant, and lightfast short fiber similar to wool, with lower density than wool, earning its nickname "artificial wool."

 

PERFORMANCE OF ACRYLIC

Form

The form varies with solvent and spinning method. The longitudinal surface of acrylic fiber has a few grooves. Fibers spun by the dry method have a dumbbell-shaped cross-section, while those spun by the wet method (using NaSCN as the solvent) are round.

 

Strength, Elongation,Elasticity

Acrylic fiber is fluffy, curly, and soft with good elasticity. However, it has large residual deformation after multiple stretches, making the cuffs and collars which is knitted or woven by arcylic prone to deformation.

Compared to wool:

• more than 10% lighter but more than twice as strong.
•  resilience is approximately equal to wool when stretched slightly.
•  Wool's resilience exceeds acrylic during wear.

 

Moisture Absorption and Dyeability

Due to its tight structure, acrylic fiber has low moisture absorption, with moisture regain of about 1.2-2.0% under normal atmospheric conditions. Its dyeability is poor but improves with the introduction of second and third monomers.

 

Thermal Conductivity and Heat Resilience

Heat Resilience:Rapidly cooling fiber under tension condition, fixing it with large internal stress, fiber is latent shrinkage when exposed to heat, that is heat resilience.

High-Shrinkage Acrylic Fiber:Fibers forced to stretch thermally under external force and possess heat elasticity.

 

Acid and Alkali Resistance

Acrylic fiber is acid-resistant but relatively sensitive to alkalis.

Lightfastness

Acrylic fiber excels in lightfastness and weather resistance, ranking best among common textile fibers. After one year of outdoor exposure, its strength decreases by only 5%, and its resistance to sunlight is twice that of wool and ten times that of cotton. Therefore, acrylic fiber is ideal for outdoor fabrics.

 

Other Properties

Acrylic has good heat resistance, with ironing temperature of 130-140°C. It with mold-resistant and insect-proof, but it has poor wear resistance and dimensional stability. Acrylic with relatively low density.

 

 

ACRYLIC FABRIC

100% Acrylic Fabric

Made entirely of acrylic fiber. For example, worsted acrylic women's suit fabric made of 100% wool-type acrylic fiber has loose structure, vibrant color, soft and elastic handfeel, and texture that is neither loose nor worn out, suitable for making mid-to-low-end women's clothing. Using 100% acrylic bulk yarn as raw material, plain or twill acrylic bulk coat fabric can be produced, featuring full handfeel and the characteristics of a wool-like fabric that is warm and lightweight, suitable for making coats, casual wear, etc., for spring, autumn, and winter.

Note: if dyeing high bulky acrylic hank yarn need use cabinet hank yarn dyeing machine; if dyeing solid acrylic hank yarn can use normal temperature hank yarn spray dyeing machine

 

Acrylic Blended Fabric

Fabric blended with wool-type or medium-staple acrylic fiber and viscose or polyester. It includes acrylic/viscose gabardine, acrylic/viscose women's suit fabric and acrylic/polyester tweed. Acrylic/viscose gabardine, also known as Oriental gabardine, is a 50/50 blend of acrylic and viscose, featuring thick and tight fabric body, durability, smooth and soft surface similar to wool gabardine, but with poor elasticity and easy wrinkling, suitable for making inexpensive pants. Acrylic/viscose women's suit fabric is an 85/15 blend of acrylic and viscose, often woven in crepe weave, with slightly hairy surface, vibrant color, lightweight, good durability and poor resilience, suitable for making outerwear. Acrylic/polyester tweed is 40/60 blend of acrylic and polyester, processed in plain or twill weaves, featuring flat and stiff appearance, durability and wrinkle resistance, but poor comfort, making it suitable for making mid-range outerwear and suits.

 

 

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.

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.

 

Cotton cone yarn dyeing,  process mainly consists of the following five steps:

PRETREATMENT

This step primarily removes natural impurities (cottonseed hulls, waxy substances, etc.) and pigmentum from the yarn, enhancing its whiteness and capillary effect to create conditions for dyeing processing.

 

DYEING

Each type of fiber has its unique dyeing characteristics, and yarn dyeing process is formulated based on  properties of cotton fibers (cellulose fibers) and reactive dyes. The process of package yarn dyeing involves applying pressure to dye solution in cone yarn dyeing machine using a pump, allowing the dye solution to penetrate from inner layer to outer layer of package yarn, thereby achieving uniform dyeing.

 

SOAPING

After dyeing, a large amount of hydrolyzed and unreacted dye remains on the surface of the yarn, which must be removed by adding soaping agent and washing under high temperature conditions (known as soaping). The role of soaping is to remove the floating dye on the yarn, improve the color brightness, and meet the fastness requirements of customers.

 

COLOR FIXATION

After soaping, for dark and medium color, fixing agent is added to achieve the processing requirements of subsequent finishing. The function of fixing agent is to form a protective film on the surface of the yarn to prevent dye from falling off during subsequent finishing processes.

 

SOFTENING

During the dyeing process, natural waxy substances on the yarn surface are destroyed, making the yarn feel harder. Therefore, after dyeing, a certain compound is added to the yarn to reduce friction between yarns, facilitating winding and subsequent weaving processes.

Whether a transparent backpack is a good design is indeed a controversial topic.

 

Proponents argue that this transparent design allows users to see what's inside without unzipping, providing a clear view at a glance. Have you ever been about to leave home and start your trip, only to suddenly wonder if you've packed something important (like keys, driver's license, wallet, etc.)? If you use a transparent backpack, you wouldn't need to open it to check again.

Moreover, this unique design might attract more attention. According to our market research, backpacks in this transparent style are more popular among children, especially little girls. Perhaps this pure design style is more appealing to little girls' hearts.

However, some people believe that this kind of backpack does not protect privacy since everything inside is visible, and the special backpack itself is more eye-catching. I think many introverted people might not like it when others' gaze lingers on their bag and counts the items inside while they are shopping.

 

Regarding privacy issues, using this kind of backpack in special occasions (such as sports events, large-scale activities) should be a good idea, as it allows staff to quickly check items and reduce potential risks, especially in popular large-event venues.

 

Ultimately, this unique design cannot please everyone, and this is true for most designs. So, do you think this transparent-style backpack is suitable for you?

 

The materials used directly determine the waterproof performance of a backpack. Previously, In the article "Which material is best for laptop bags?", we previously introduced some commonly used waterproof materials. However, the overall waterproof performance of a backpack depends not only on the materials but also on the waterproof capabilities of the zippers.

Zippers are one of the weakest points in any waterproof gear. If designed poorly, water can seep in, compromising the integrity of the equipment. Therefore, high-quality zippers are essential for maintaining waterproof standards, especially in outdoor environments. The two common types of zipper waterproofing treatments are waterproof zippers and water-resistant zippers.

Understanding the difference between waterproof and water-resistant zippers is crucial. Water-resistant zippers are usually treated with a coating that helps repel water, making them suitable for light rain or splashes. In contrast, waterproof zippers are designed to completely prevent water from entering. These zippers typically feature a sealed or taped construction to ensure comprehensive protection against moisture.

 

Types of Waterproof Zippers

1.Coated Zippers: These zippers have a waterproof coating that helps repel water and are commonly found in many outdoor products.

2.Taped Zippers: Taped zippers have waterproof tape covering the seams, sealing the zipper and preventing water ingress. This type is often found in high-end outdoor gear.

Additionally, some designs of waterproof backpacks also enhance waterproofing, such as fabric flaps covering the zippers, effectively preventing rainwater from entering.
