FAQ

Yercan Textile shares two commonly used methods for identifying yarn fibers:

I. Tactile and Visual Inspection Method

This method involves touching the fibers with your hands and observing them visually, relying on experience to determine the fiber type. This method is simple and requires no instruments, but it demands extensive experience from the inspector.

1. Feel and Strength: Cotton and linen feel relatively stiff, while wool is very soft. Silk, viscose, and nylon have a moderate feel. When pulled apart, silk, linen, and cotton feel very strong; wool and viscose fibers feel weaker.

2. Elongation: When stretching the fibers, cotton and linen have a relatively small elongation; wool and acetate fibers have a relatively long elongation; silk, viscose, and most synthetic fibers have a moderate elongation.

3. Length and Uniformity: Natural fibers have poor length and uniformity, while chemical fibers have better length and uniformity. Cotton fibers are fine and soft, and very short. Wool is longer, crimped, soft, and elastic. Silk is long and fine, with a unique luster. Linen fibers contain gum and are stiff.

4. Weight: Cotton, linen, and viscose fibers are heavier than silk; nylon, acrylic, and polypropylene fibers are lighter than silk; wool, polyester, and vinylon acetate fibers are similar in weight to silk.

II. Burning Method The burning method is a common method for identifying yarns, utilizing the characteristics exhibited by textile fibers during combustion.

Cotton: Ignites easily near a flame, burns relatively quickly, leaves ash with a paper-like smell, very little ash, soft, and black or gray in color.

Wool: Melts and burns, difficult to continue burning, self-extinguishes, smells like burning feathers, ash is brittle and black in color.

Silk: Makes a hissing sound when burning, difficult to continue burning, self-extinguishes, and splatters when burning, smells like burning feathers, ash is brittle and black in color.

Linen: Ignites easily near a flame, makes a popping sound when burning, continues burning and produces smoke, leaves ash, and the ash is black or gray in color.

Adhesive: Ignites easily near a flame, burns extremely quickly with no ash, produces a chemical odor when burning paper, and leaves no ash except for those without luster.

Yercan wool spinning feather yarn, also known as eyelash yarn, dog hair yarn, pine yarn, long tail yarn, etc., is woven by a crochet machine. The raw materials can be nylon, polyester, polyester-nylon blends, wool-nylon, etc. It consists of warp-core yarn and weft-feather yarn (feathers are formed after the weft yarn is cut by a blade). It is mainly used for knitted sweaters, scarves, gloves, socks, accessories, and carpets.

Feather yarn is very popular with women because of its soft feel and abundant down.

Below, we will discuss some points to note regarding the twisted nylon feather yarn that has become popular in recent years.

(1) Choose suitable raw materials and treat them specially.

The raw materials must be made from imported nylon chips to prevent color variations and color differences. The raw materials must be steam-heat-set beforehand; otherwise, curling and color variations will occur.

(2) Replace the cutting blade in a timely manner.

If the blade is not replaced or inspected in time, it will result in severe shedding and uneven feather length. This applies to all feather yarns. (3) Finished Product Inspection.

The finished feather yarn may contain lint-free yarn or oil-stained yarn. These must be inspected by a designated person to remove substandard yarn. Oil-stained yarn can only be dyed in dark colors or treated by the dyeing factory before dyeing.

(4) Twisting and Rewinding.

The twisting should be large, and the frame length should be long to facilitate rewinding later. Otherwise, rewinding will be difficult, resulting in significant waste. The weight of the twisting should ideally be less than 0.25 kg; otherwise, the nylon will become uneven. During the later rewinding process, pay attention to the direction of the lint; the direction of the lint should be consistent.

(5) Dyeing Control.

1. Because nylon raw materials dye quickly, it is difficult to dye evenly, easily resulting in uneven color and color difference. Therefore, during dyeing and finishing, the temperature must be raised slowly with a retarder, and the temperature drop must be well controlled. Different batches of nylon raw materials should not be mixed for dyeing, as this will result in uneven dyeing.

2. Dyed feather yarn should not be dried too much using a drying machine. Over-drying will cause problems such as loose lint, color difference, and poor hand feel. Pujiang Yercan Textile Technology Co., Ltd., formerly known as Zhejiang Zhenai Wool Textile Co., Ltd., was established in 1995 and is now located in Gutang Industrial Zone, Yiting Town, Yiwu City, Zhejiang Province.

It is a key enterprise in the wool textile industry in Zhejiang Province. Daily output is 6 tons, annual output exceeds 2,000 tons, and annual sales reach 50 million yuan. It can undertake various customized orders both domestically and internationally.

More and more modern urbanites prefer to wear clothing made of natural materials such as cotton, linen, and wool because they are environmentally friendly and healthy. Now, the editor from Yercan Wool Textile will share with you how to wash cotton sweaters to prevent fading.

1. The main characteristics of cotton clothing are comfort, breathability, sweat absorption, and harmlessness to the human body. Cotton has good dyeing properties, but dyed cotton yarn will fade to some extent, especially darker colors. When washing, it should be separated from other cotton clothes, and the soaking time should not be too long. Mix the pure cotton detergent and solution evenly before soaking the clothes; otherwise, the fading will be uneven.

2. The optimal water temperature for washing is 30-35 degrees Celsius. Soak for a few minutes, and after washing, air dry in a cool, ventilated place. Do not expose to direct sunlight to avoid fading.

3. It is recommended to use alkaline detergents (such as soap) because cotton yarn is dyed in an alkaline environment, so alkaline detergents will accelerate fading. Using a detergent specifically for pure cotton would be even better.

4. Adding 1-2 tablespoons of salt to the detergent during washing can also prevent clothes from fading.

5. When drying, turn the sweater inside out, with the lining facing the sun and the outer layer in the shade. Sunlight can cause the dye to change color.
