The dyeing and finishing production process of cotton-knitted fabrics includes scouring, bleaching, dyeing, printing, finishing, and other processes. It plays an important role in improving the appearance of knitted fabrics, improving performance, improving product quality, and increasing varieties of designs and colors. 1. Scouring and bleaching The main processes of scouring and bleaching of cotton knitted fabrics are: scouring, bleaching, alkali shrinkage, waxing, etc. Among them, the processing principles and agents of scouring and bleaching are the same as those of cotton cloth, and will not be repeated. However, cotton knitted fabrics are connected by loops, and the gaps between the yarns are large, which are easy to deform and cannot withstand large tensions. Therefore, loose processing equipment must be used during processing. The following is a brief introduction to the processes of alkali shrinkage and waxing. POLYESTER/SPANDEX SHINNINGFABRIC 31SP002 1) Alkali shrinkage: Alkali shrinkage of cotton knitted fabrics is the process of treating cotton knitted fabrics with concentrated alkali in a relaxed state. Cotton fiber expands in concentrated caustic soda, the fabric shrinks, and the fabric density and elasticity increase. For the processing of fabrics such as loose jersey, alkali shrinkage includes three steps, namely padding with lye, stacking shrinkage, and washing to remove alkali. 2) Waxing: after scouring and bleaching of cotton knitted fabrics, after the oil and wax substances of cotton fibers are removed, the friction between fibers increases. When sewing, because the fibers do not easily slip, the needles are easy to break the fibers and cause needle holes in the fabric, which affects the wearing fastness. To solve this problem, in addition to strictly controlling the process conditions, softening treatment, that is, waxing, is carried out at the same time. The dehydrated fabric is dipped in paraffin emulsion, and then dehydrated and dried. 2. Dyeing and printing The dyeing and printing of cotton knitted fabrics are the same as those of cotton fabrics and will not be repeated here. Loose processing equipment such as rope dyeing machines should be used for dyeing. Prints are hand-printed or lithographed. 3. Finishing The finishing of cotton knitted fabrics mainly includes shrink-proof finishing and pile finishing. Cotton knitted fabrics are susceptible to stretching and accumulated deformation during dyeing and finishing. Once washed, the accumulated deformation of the fabric will retract, causing dimensional changes. Anti-shrinkage finishing is the forced retraction of the fabric in the state of damp heat relaxation so that the size of the fabric is stable. Cotton-knitted flannelette needs to be piled up. Fleece finishing is pulling out the fibers in the floating threads of the knitted gray fabric to form and fluff, to make the fabric soft. Thin feel with enhanced warmth. Different types of cotton knitted fabrics have different dyeing and finishing processes.

1. Bamboo fiber blended fabric Bamboo fiber is a new type of regenerated cellulose fiber, which has the characteristics of good strength, high wear resistance, good moisture absorption and moisture conductivity, good air permeability, and good antibacterial performance. The dyeing and finishing processing method of bamboo fiber/fine denier polyester/cotton blended knitting yarn, its technological process is: gray fabric preparation→alkali weight reduction→bleaching→dyeing→softening finishing→post-treatment→finished product. The purpose of alkali reduction is to improve the wearability of fabrics, NaOH20-35g/L, 125℃ for 35-45min; dyeing with dispersing and reactive dyes; softening with 4% softener SGS, 35-45℃ for 30-40min; The post-treatment adopts calendering and setting, 95-100 ℃, overfeeding 13-15%, so that the bamboo fiber blended knitted fabric has a unique style of smooth, soft, waxy and cool. 100% POLYESTER TRICOT BRUSHED 33P012 2. Mercerized wool light fabric For 25rex single warp and single weft mercerized wool light and light fabric, IA0 bio-enzyme has the best desizing effect, and the size will be completely removed, which is beneficial to dyeing and finishing. A reasonable selection of dyes and auxiliaries is an important measure to overcome the fast color absorption and easy dyeing of mercerized wool. In the oxygen bleaching process, wool protectants can be selected, which can alleviate the damage of wool and give the wool fabric a plump and elastic feel.

One is clothing made of functional fabrics for outdoor sports. This type of fabric is mainly mountaineering clothing, ski clothing, and assault clothing. Has a protective effect. The other is clothing made of outdoor leisure functional fabrics, which are defined as outdoor activities outside the house. This type of fabric is mainly casual and fashionable, with fine workmanship, soft hand feeling, and comfortable wearing. It is suitable for tourism, outdoor activities, etc.. 1. Clothing made of this fabric is very comfortable, and we don't feel the discomfort caused by sweat during exercise; 2. This kind of fabric can make the sweat on the body drain to the surface of the clothes faster; 3. It uses a special weave method to export excess sweat from the skin surface to the outer layer of the fabric; 94% NYLON 6% SPANDEX SATIN FABRIC MFD-002 UV protection fabric 1. There is no need to worry about the skin being sunburned when wearing clothing made of this fabric; 2. This fabric has an anti-ultraviolet function (UPF 30+), which can better protect the skin from ultraviolet rays; 3. Woven or knitted sunscreen materials rely on the transfer, absorption, and reflection of UV rays Hyvent of the fabric; Waterproof and breathable fabric 1. Wearing clothes made of this fabric for outdoor sports, even if it rains heavily, there is no need to worry about getting wet; 2. Polyurethane (PU) coating, rainproof and breathable; 3.

Polyester super soft velvet fabric is a type of synthetic fabric that is known for its soft, smooth, and luxurious feel. It is made from polyester fibers, which are synthetic fibers that are known for their strength, durability, and resistance to creasing and wrinkling. Polyester super soft velvet fabric is typically made with a short, dense pile that creates a smooth, velvety surface and is known for its resistance to wear and fading. It is also relatively easy to care for, as it is machine washable and resistant to wrinkling and shrinking. Some other characteristics of polyester super soft velvet fabric include: It is lightweight and flexible, making it comfortable to wear and easy to drape. It has good resistance to fading, meaning that it retains its color well over time. It is resistant to moisture, making it a good choice for use in garments that may be worn in damp or humid environments. It is relatively inexpensive, making it a budget-friendly option for a wide range of applications. It is easy to care for, as it can be machine washed and dried on a low heat setting.
