Grass cloth washing - often appears the problem Music in Japan

A, washing time is too long

towel washing in the washing machine, most of the time is constantly rolling up and down, rub, rub are produced by movement. The rub, friction movement is an important factor of towel to clean, because it is dirty towels soaked in lotion is unable to wash, the rub, friction movement both play a role of a clean towel, also wear the fiber at the same time, reduces the fastness of towel. Therefore, reasonable control of the washing time can reduce unnecessary wear and tear, thus ensuring the normal washing towel.

2, dehydration when multiple high speed high

high part of automatic washing off so quickly, the dewatering machine speed is too high, too strong centrifugal force makes the towel, cotton fiber larsson as we use hand wring dry towel overexert, loosely woven structure, or in the middle of this cause towel overall osteoporosis is damaged, the normal damage usually starts from the side.

3, drying temperature is too high, the time is too long

some dryer air cooling is broken, can cause excessive and dry towel. As a result of the cotton fiber wet strength is higher than dry strength, therefore baked too dry, cause towel fastness of decline. Textile spinning workshop control requirements for air humidity is high, the air is dry, slightly has broken yarn, the spinning workers busy beheaded, has affected the normal production. Towel if baked overheating will cause fiber brittle, towel fastness decreased obviously.

4, look for reasons from the aspects of chemical

in the process of washing water is not clear, the residue chemicals within a fiber of towel.

1, alkaline chemicals residual

although alkaline chemicals in the process of washing of cotton fiber is safe, not injury fiber towel, but water is not clear to make alkaline detergent residues within a fiber towel, towel drying, can make a gray towel to harden and softness. As is known to all, towel and linen tablecloths, the actual use of state is completely different, linen tablecloths and is used in the static condition, and towels are used in dynamic conditions and regular fold knead, twists requirements must be soft towel, towel from any cause to harden can reduce towel fastness.

2, residual chlorine bleaching agent

chlorine bleaching agent is one of the more strongly in washing chemicals, its bleaching function make the pigment on the distribution of most parts can be removed when rinsing, but has some of the damage to the cotton fiber is, the quantity is reasonable, the humidity control ideally is perfectly normal. But on the excess, improper control of temperature and the water is not clear, form of chlorine residue, that for fabric, damage is no doubt about it.

3, pickling, improper

sometimes in order to solve the bad water quality causes such as towel hair grey, yellow, often use strength strong oxalic acid for pickling, to resume the whiteness of towel, but this towel is susceptible to damage, the cotton fiber acid not alkali, acid pickling, usually used as the service life of towels may be significantly reduced.

neutralizer is normal washing process in the last program on chemicals, before dropping can neutralize after several washing procedure and after water residue in the cloth in small amounts ( Not more than 10 PPM) Alkaline chemicals and chlorine bleaching agent, dissolve and some metal ions in the water, the correct quantity can make cloth pieces of PH adjustment in 5. 5 - 6. Between 5, with human skin PH value, is safe, the fabric will remain the normal service life period. But not the local extensive use of neutralizing agent, can make the fabric partial acid, reducing fabric fastness.

4, towels, problems of its own

countries about the quality of the towel is hierarchical, different level reflects the different quality. Towel quality on the market at present the good and bad are intermingled. Towel the quality problem of reason is various, the multiple links, such as raw materials for production of cotton towel, cotton yarn of the raw materials for cotton. If the cotton is chaos phenomena, such as cotton quality can't guarantee. There have been some hotel towel quality is bad, towel washed a few times it broke.

5, laundry tank quality whether qualified

the washing tank is made of stainless steel welded together, coaming on small holes, in the manufacturing process should be carried out on the back of the hole deburring processing, but if the quality of this process is unqualified, saved a lot of burr or individual burr untreated, it will cause the phenomenon of hook fabric; Another V may be due to bladder muscle with coaming connection place has clearance to cause, the variant in the washing tank will be due to the heat bilges cold shrink, some of the tank often small clearance due to expand when heated, fabric in washing or drying to the cause, uneven clearance, when the fabric by gap big sandwich, with bladder turn to clearance by extrusion force through small, easy to tear the fabric loss.
