3·2 Antibacterial and hygroscopicFabric(Cloth)FinishingProcess
(a) Bleached cloth
Turn Seam printing → singeing → deboiling → bleaching → mercerization → pre-styling → moisture absorption and perspiration finishing → whitening and soft shaping → pre-shrinking → finished product
(b) Full-color cloth
Seam-turn printing → singeing → deboiling → bleaching → mercerization → pre-styling → dyeing → antibacterial, deodorant and hygroscopic finishing → soft shaping → pre-shrinking → finished product
(c) Yarn-dyed fabric
Seam-turning printing → singeing → alkali oxygen deboiling and bleaching → mercerization → pre-styling → antibacterial, deodorant and hygroscopic finishing → Soft shaping → pre-shrinking → finished product

Padding working fluid (20-40℃; liquid rolling rate 70%) → hot air Drying (80-110℃ 6-10 points)→Tenter (160-170℃, 30 seconds)→wash→dry
Notes: Due to Hygroscopic finishing agent has the same crystalline form as the polyester molecular unit. It can produce a crystallization reaction at high temperatures, causing a hygroscopic layer on the polyester surface, making it hydrophilic. In the finishing process, the softener used is very important. Hydrophilic softeners must be used to make polyester-cotton fabrics have excellent hydrophilic effects. For some softeners with water-repellent effects, adding them will block the grafting channels of the hydrophilic agent and form a water-repellent film.
4、Fabric(Cloth)Test results
At present, there is no unified standard for hygroscopic comfort in China, but based on the fact that sweat first wets clothes, then penetrates to the surface, and dissipates heat through evaporation, we use capillary effect and water droplet diffusion to detect the hygroscopic effect .
The characteristic indicators for evaluating the wearing comfort of fabrics include three points: the heat transfer performance of textiles, the transfer performance of fabrics to moisture, and the transfer performance of textiles to air. This The three factors have different weights for different seasons and different layers of clothing fabrics. For winter underwear, the two factors of heat transfer and air transfer are focused, and for summer outerwear, the moisture transfer and air transfer are focused. These two factors.
(1) Capillary effect test results
Capillary effect: greater than lOcm/3Omim (samples were taken on the fabric respectively Three parts on the left, middle and right, and then take the average value)
(2) Water droplet instantaneous diffusion experimental results
Method: on the cloth Place 5 pieces of water permeability test paper underneath, drop 5ml of water on the sample cloth, calculate the time (sec) required for the water droplets to completely penetrate into the fabric, and conduct 10 tests, and then take the average value.
(3)Antibacterial test results
(a)Anti-mite performance test results: The test results show that the repellent rate of anti-mite and antibacterial fabrics against dust mites, leather mites and chiggers is greater than 99%.
(b) Antimicrobial spectrum measurement results: The results show that the anti-mite antibacterial finished fabric can completely kill Staphylococcus aureus, Staphylococcus epidermidis, Bacillus cereus, Streptococcus, Pneumococcus, Meningococcus, and Neisseria gonorrhoeae , Escherichia coli, Shigella dysenteriae, Typhimurium, Pneumoniae, Pseudomonas aeruginosa, Bacillus subtilis, Epidermophyton floccosum, Trichophyton gypsum, Candida albicans, Penicillium, Aspergillus niger and other harmful bacteria.
(c) Washing resistance of anti-mite and antibacterial fabrics: The repellent rate of dust mites, leather mites and chiggers reaches more than 95% after 50 washes. Neisseria gonorrhoeae (941748 domestic epidemic strains), Neisseria gonorrhoeae (WHO Q6 international standard drug-resistant strain), Staphylococcus aureus (ATCC 6389), Escherichia coli (ATCC 8099), Candida albicans (ATCC l0231), Microsporum gypsum , Epidermophyton floccosum, Trichophyton rubrum, Bacillus subtilis black variant spores (ATCC 9372), etc. do not grow at all on antibacterial fabrics that have not been washed or washed 30, 50, and 100 times, and the antibacterial rate reaches 99% As mentioned above, the anti-mite and antibacterial finishing cloth has excellent washing resistance.
Conclusion
PolycottonFabric (Cloth)Through moisture-wicking, antibacterial and anti-odor finishing, makePolyester-cotton blendedFabric “>(Cloth)This A traditional product has been fundamentally improved in terms of comfort performance, improved moisture absorption, improved hygienic conditions, and has better strength, stiffness and dimensional stability than cotton fabrics, giving the fabric outstanding hygroscopicity and antistatic properties And soft touch, excellent washability and easy stain removal. High-end shirt fabrics that have become famous brands.
