3·2 Antibacterial and hygroscopic fabric (cloth) finishing process
(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
Turning and printing → singeing → deboiling → bleaching → mercerization → pre-styling → dyeing → antibacterial, deodorant and moisture-absorbing finishing → soft shaping → pre-shrinking → finished product
(c)dyed fabric
Turning printing → singeing → alkali oxygen deboiling and bleaching → mercerization → pre-styling → antibacterial, deodorant and hygroscopic finishing → soft shaping → pre-shrinking → finished product
3.3 Process prescription
SCJ-8915Og/L
Moisture wicking finishing agent SW40-50g/L
Penetrant 2 g/L
Polyester whitening agent 0～3g/L
Softener (hydrophilicity) 30g/L
3·4 Process Flow
Padding working fluid (20-40℃; padding rate 70%) → hot air drying (80-110℃ 6-10 minutes) → tenter (160-170℃, 30 seconds) → water washing → drying
Note: Since the 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 to form on the surface of the polyester, 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 moisture transfer performance of fabrics, and the air transfer performance of textiles. These three factors have different weights for different seasons and different levels of clothing fabrics. For winter underwear, we focus on the two factors of heat transfer and air transfer. For summer outerwear, we focus on moisture transfer and air transfer. These two factors are sex.
(1) Capillary effect test results
Capillary effect: greater than 1Ocm/3Omim (samples are taken from three parts of the fabric, the left, middle and right, and then the average value is taken)
(2) Results of water droplet instantaneous diffusion experiment
Method: Place 5 pieces of water permeability test paper under the cloth, 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 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, Neisseria gonorrhoeae, and Escherichia coli , dysentery, typhoid, pneumonia, 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: after 50 washes, the repellent rate against dust mites, leather mites and chiggers reaches over 95%. Neisseria gonorrhoeae (941748 domestic epidemic strains), Neisseria gonorrhoeae (WHOQ6 international standard drug-resistant strains), Staphylococcus aureus (ATCC6389), Escherichia coli (ATCC8099), Candida albicans (ATCC10231), Microsporum gypseum, and flocculent epidermis Ringworm, Trichophyton rubrum, Bacillus subtilis black variant spores (ATCC9372), etc. do not grow at all on antibacterial fabrics that have not been washed or washed 30 times, 50 times, and 100 times. The antibacterial rate reaches more than 99%. This anti-mite Antibacterial finishing cloth has excellent resistance to washing.
Conclusion
The polyester-cotton fabric (fabric) is finished with moisture-wicking, antibacterial and deodorant finishing, which fundamentally improves the comfort performance of the traditional product of polyester-cotton blended fabric (fabric), improves the moisture absorption effect, improves sanitary conditions, and is better than cotton fabrics. It has better strength, stiffness and dimensional stability, giving the fabric outstanding hygroscopicity, antistatic properties and soft feel, excellent washability and easy stain removal. High-end shirt fabrics that have become famous brands. 8elywMDx
