What to do when fabric pilling? Several ways to prevent pilling

What about fabric pilling? There are several methods for anti-pilling finishing, and there are many methods for anti-pilling. The methods before dyeing and dyeing are like changing the structure, composition and properties of the fiber, changing the spinning process and fabric structure of the yarn, changing the dyeing and finishing process, etc. However, we are generally used to finishing cloth and clothing after dyeing, the methods are: 1, bio-polishing (biological enzyme finishing) Bio-polishing is a process for improving the surface of cotton fabrics with cellulase to achieve long-lasting anti-pilling effect and increase the smoothness and softness of the fabric. Bio-polishing removes fine fibers protruding from the surface of the yarn, and the surface of the fabric has large fluff. Reduce, become smooth and not pilling. (The hydrolysis of the enzyme and the mechanical impact together remove the fluff and fiber ends of the fabric surface, making the fabric structure clearer and brighter.) The method is effective in reducing the pilling effect, because the tip of the fiber is removed rather than covered in the original place, but it should be noted that this method will have some loss of fabric strength and partial weight loss. For cotton and polyester/cellulosic fiber blend fabrics, cellulase is used; wool or polyester/wool blend fabric is polished with a suitable bio-protease. Therefore, the process conditions must be strictly controlled, otherwise the enzyme inactivation or serious damage, serious weight loss, and large-volume fabrics are not suitable (there are cylinder differences), so some knitted fabric dyeing and finishing factories are not willing to apply this method. 2, light fluffing method (mainly used for wool fabrics, such as sweaters, wool knitwear) After the knitwear such as sweater is lightly fluffed, the root of the wool fiber is felted in the yarn, and the fibers are entangled with each other, thereby enhancing the friction coefficient between the fibers, so that the fiber is not easy to be subjected to friction. The yarn is slid out, which in turn reduces the pilling of fabrics such as sweaters. At present, fabrics such as worsted sweaters are generally lightly fluffed to improve their anti-pilling effect. The process is: sweater infiltration - mild fluffing - cleaning - dehydration - drying. 3. Resin finishing method 1 principle Resin is a kind of polymer, which uses the function of resin to form a film on the surface of the fiber, so that the surface of the fiber is covered with a wear-resistant resin film, which makes the slip of the fiber weaken. At the same time, the tree refers to The evenly interlaced chain condenses on the surface layer of the yarn, so that the fiber end adheres to the yarn, and it is not easy to pilling when rubbed, thereby effectively improving the pilling resistance of the sweater. 2 resin selection The selected resin must have a large adhesion to the fiber, and it should also have a certain strength. It should have better elasticity and smooth and non-sticky feel after finishing. The adhesive film does not affect the color of the dye. Fastness and gloss. No irritation to human skin. No odor; tree refers to stable performance, convenient, reliable and low price. At present, the general resin (acrylic self-crosslinking type tree finger) can not meet the high requirements of customers for fabrics, because some anti-pilling agent (resin) has a hard feel after treatment, and the strength is lowered, and the processed object is colored. Some changes have occurred, and some resins must also be subjected to high temperature baking and the like. The foreign countries have gradually phased out and gradually developed a new generation of anti-pilling pilling agent. Its main products are polyurethane-based polymers and silicone resins. Now these products have been produced domestically and have been widely used in the production of knitwear. Anti-pilling finishing.

Cutting mattress fabrics more efficiently

Many manufacturers of mattresses in order to improve production efficiency, and the cutting of mattress fabrics in the entire production process is a lot of manpower and time, to improve efficiency, first of all, from the cutting process,

Mattress fabric cutting equipment needs to meet the following characteristics:

1. Fast cutting speed: It must have rich experience in R&D design and manufacturing. The cutting speed of the equipment developed by the industry should be leading, and the active round knife cutting is generally 20%~30% faster than similar products;

2. Typesetting and material saving: Extremely automatic and close typesetting function, which minimizes material waste and improves fabric utilization;

3. Cutting tool: configuration active round knife tool, single layer cutting fabric, imitation leather or other fabric materials without film, can also be equipped with vibrating knife tool to achieve multi-layer cutting;

4. It is convenient to change the scale: it can quickly change the size for personalized customization, convenient and fast, and save the type data permanently;

What is the material of the down fabric? What are the characteristics?

Down cloth is generally a thin knitted fabric with a relatively small density value or a relatively high density, because it is usually used as a fabric for down duvets, a down garment, and can prevent the feather from flowing outward, which is also called a feather-proof cloth. flannel.

Down fabrics are usually made of pure cotton or polyester. The down fabrics are usually woven with plain weave. The warp and weft yarns are generally used on yarns with a lower density of the combing wire, usually in the range of 10-29 tex. between. The warpness of the warp direction is usually above 73%, the weft tightness is usually above 53%, the total tightness is above 80%, and the tightness of the fabric is usually high.

The use and characteristics of downcloth:

The structure of the down fabric is very tight, shiny, breathable and anti-feather, firm and wearable, smooth and smooth. The fabric is cleaned by anti-feathering, etc., which can reduce the vacancy between the warp and weft of the knitted fabric, and further prevent the feather from being drilled. In addition, the medium-tight knitted fabric can be treated with a chemical coating to prevent the feather from being drilled.

Analyze the specific application of knitted fabric

Knitted fabrics can be woven into grey fabrics and then cut and sewn into various knitwear; they can also be directly woven into fully formed or partially formed products such as socks and gloves. In addition, knitted fabrics are widely used in the fields of industry, agriculture, and medical care, in addition to underwear, outerwear, socks, gloves, hats, sheets, bedspreads, and curtains.

First, the flexibility of knitted fabrics

Knitted fabrics have good stretchability, and can minimize seams, pleats, splicing, etc. designed for styling during model design. Secondly, knitted fabrics are generally not suitable for the technique of recursive and hot pressing. Instead, the elasticity of the fabric itself should be used to suit the human body curve, and the knitted garment must be designed according to the fabric structure used. If it is a particularly elastic fabric (related to the yarn and structure used), not only can it be left loose when designing the model, but its model size can be the same as the human size, and the elastic coefficient can also be considered. Reduce its size.

Second, pay attention to the disengagement of knitted fabrics

Knitted fabrics are different in style and characteristics from woven fabrics. The style of their garments not only emphasizes the advantages of fabrics, but also overcomes their shortcomings. Due to the shortcomings of individual knitted fabrics, it is necessary to pay special attention to the use of some knitted fabrics in the design and production of prototypes. Do not use too much exaggeration techniques, and do not design provincial and cutting lines as much as possible. Too much to prevent the occurrence of the disengagement of the knitted loop and affect the takeability of the garment. The most correct way is to use simple and soft lines to harmonize with the soft and versatile style of knitwear.

Third, pay attention to the curling of knitted fabrics

The curling property of the knitted fabric is the edge fabric wrapping phenomenon due to the disappearance of the stress in the edge coil of the fabric. It should be noted that the curling property is a disadvantage of the knitted fabric, which may cause unevenness of the seam of the garment piece or a change in the size of the edge of the garment, which ultimately affects the overall styling effect of the garment and the size of the garment. However, not all knitted fabrics have curling properties, but fabrics of individual structure such as weft knitted fabrics; for this fabric, the fabric can be edged and framed by adding and sizing. Ribs or piping and inlays on the edges of the garment.
