Spinning process process of UV-protected fabrics

UV-protected fabric production technology

Ultraviolet light has a bactericidal function on bacteria, but it can also bring harm to human skin.

Human skin can undergo two different photobiological reactions after being exposed to UV light, one being immediate tanning.

the second is late onset tanning spots, the former being caused by long-wave UVB UVA and visible light, with melanin distributed at the base of the skin.

The latter is caused by shorter wavelength UVB irradiation, where melanin is distributed throughout the base and causes epidermal thickening, damaging skin cells and DNA.

How to prevent UVB damage to the human body, the most effective way is to develop and develop fabrics with UV protection function, using UV protection fabrics to design and make different personalities of shirts, swimwear, outerwear, special class and many other garments.

UV-protective fabrics, from spinning to weaving, are basically the same process as the conventional anti-yarn and weaving methods.

Spinning process flow and process characteristics 

Process flow 

Polyester: cotton → combing → pre-combined → mixed with a → mixed with two and → mixed with three and → roving 

Cotton: clear cotton → combing → pre-combined → strip roll → combing → spinning → winding → twisting → winding

Process characteristics 

①Cotton clearing process: UV resistant polyester staple fiber and cotton fiber are processed separately, each into a roll, and the volume quantification of UV resistant polyester fiber is similar to the volume quantification of conventional polyester fiber.

②Combing process: The carding process requires meticulous combing to solve the abnormal phenomenon of fiber winding around the sill, doffer, cover, etc., and to reduce the bent hook fibers that generate cotton knots. In order to adapt to the UV-resistant polyester fiber processing, should be used to light quantitative, multi-transfer process measures.

③ and coarse process: and coarse process is the key to control the polyester pure and quantitative, to solve the anti-UV fiber material due to the addition of winding flowers and static electricity.

In order to make the production go smoothly, the roller speed should be lowered and the drafting times should be reduced, so that the mouth of the couch is clean and the fiber channel is free of oil burrs, and the roving weight is lighter than that of conventional spun yarns of the same count.

④Fine yarn process: fine yarn process mainly solve the problem of winding roller, leather roller, in order to increase the strength of the yarn, because the anti-UV polyester fiber is a general strong and stretch type fiber, so the strength is low, and because the fiber is easy to wind, easy to stick, so, the draft multiple of the fine yarn machine is lower than the same count yarn, while requiring the yarn channel is clean, leather roller is clean, the back roller separation distance is larger, in order to reduce the strength loss of fine yarn.

⑤ in the operation: spinning part of the main grasp of the machine cleaning work, so that the yarn channel clean, not blocked, each process using the container to clean, clean ground without oil.

In the spinning process no longer increase around the tin forest, dawning, cover, roller and other acquired factors. 

Weaving process flow and characteristics of each process flow

Process Flow 

Warp: Winding → warping → sizing → reed drawing → weaving → inspection → finishing → storage 

Weft: Winding cylinder → weft winding → yarn steaming → weaving → inspection → finishing → storage

Process characteristics of each process 

①Winding process: The main purpose is to control the tension of yarn and keep the tension of single yarn and piece yarn small and even.

The winding machine uses electronic yarn clearer, the winding machine speed is 2200-2400 rpm, the warping machine line speed is 240 m/min, the winding cylinder adopts small tension, the tension circle weight is 90 g.

②Sizing process: As the warp yarn of UV-protected poplin is high count, high warp density and easy to elongate, therefore sizing is the key process of weaving production.

Sizing to be mainly covered, penetration as a supplement, sizing to choose a high enhancement low stretch low viscous high density sizing to achieve enhanced stretch reduction, hair feather applique, smooth twisting, head reduction, the purpose of reducing the shadow.

③ weaving process: UV protection poplin warp yarn density, in the weaving process to prevent warp yarn adhesion to each other, weft cross file, weaving to use large tension, high back beam, small double layer double tread plate opening weaving process, so that the loom opening clear, reduce friction, to obtain a rich fabric, good appearance style, less blemishes, good quality weaving effect.

UV protection poplin fabric warp and weft yarns are used low proportion of anti-UV polyester fiber and cotton fiber blend of high count combed strands, and woven with high density.

Thus the fabric has fine, light, smooth, breathable, cotton sexy fabric style, after half bleaching, full bleaching, dyeing and finishing process processing, can be made with anti-UV function of senior men's and women's shirts and golf clothing fabric.
