Description

Rapid humidifying device for loose fibers

Technical Field

The invention relates to a humidifying device, in particular to a loose fiber rapid humidifying device, and belongs to the technical field of textile machinery.

Background

Textile materials have a certain moisture absorption capacity, so that the moisture regain of various textile materials is uniformly regulated both internationally and domestically in order to meet the requirements of weight and price checking in the trade of textiles. Effective control of the moisture regain can provide a significant economic benefit to the textile mill. Secondly, the control of the moisture regain in the fiber can also reduce the damage to the fiber in the production process, for example, in a combed cotton process, when the moisture regain of the fiber is too high, the cotton roll is easy to stick to the roll and form neps through kneading, so that the yarn quality is influenced; when the moisture regain of the fiber is too low, the combed sliver is hairy, the fiber is easy to break during combing, short fibers and flying are increased, combed noil is increased, the cost of cotton use and the weight of combed sliver are uneven, and the evenness of sliver is deteriorated. The realization of the accurate control of the fiber moisture regain is an important subject in the textile industry.

Xinjiang is an important cotton planting area and a high-yield area, the yield of seed cotton is about 500 million tons at present every year, the seed cotton accounts for 80% of the national yield, the proportion of mechanically picked cotton is higher and higher along with the great increase of the cost of manually picking cotton, the impurity content of the mechanically picked cotton is generally much higher, and in order to remove the complex impurities, an over-drying mode is adopted by a cotton ginning mill to conveniently remove leaves, grass thorns and the like. When the excessively dried seed cotton is subjected to cotton seed removal on a cotton gin, the damage to cotton fibers is large, the neps are more, and the clothing loss is high; therefore, the cotton fiber can be quickly humidified and remoistened after impurity removal, and the quality and the yield of the cotton fiber are improved.

Chinese patent publication No. CN 104963132 a discloses a fiber humidifier, which includes: an upper humidifying mechanism, a lower humidifying mechanism and a product channel between the upper and the lower humidifying mechanisms. The technical scheme disclosed in the patent can play certain help to the promotion of fibre moisture regain, nevertheless can not guarantee the homogeneity of humidification, also can not reach the requirement of retrieving the dust removal, more can not satisfy the demand of different fibre to different moisture regain.
