Description

Improved garment processing technology

Technical Field

The invention relates to the technical field of garment fabric processing, in particular to an improved garment processing technology.

Background

Leather is taken as a main garment material, which is closely related to people in daily life, leather products are increasingly favored by people due to excellent performances of durability, dirt resistance and the like, the processing of the leather garment material comprises a series of complex processing processes, each process plays a crucial role in the quality, appearance and the like of the leather material, particularly, the tanning process has the greatest influence on the leather material, the existing tanning process for the raw leather material comprises putting the raw leather into a rotary drum containing a tanning agent solution, and tanning is carried out through the rotary drum, and the leather grain surface is rough and the leather surface is possibly damaged due to the fact that the raw leather is thrown, collided, rubbed, extruded and the like continuously; another way of tanning is to immerse the hides in a solution with tanning agents for tanning, which is preferred by leather manufacturers, since it does not subject the hides to a great deal of impact forces like a drum. For example, patent document 1 discloses a method for tanning leather, in which a belt 3 is tensioned by a tanning roller and a loading/unloading roller provided at both ends, the leather sheet is fixed on the belt 3, that is, the belt 3 is wound on the tanning roller, and at the same time, the tanning roller is placed in a tanning tank 2 with tanning liquid, thereby tanning the leather sheet, and at the same time, a pressure roller driven by an oil cylinder is provided above the tanning roller, thereby squeezing and releasing the leather sheet, thereby fully immersing the tanning liquid into the leather sheet, and further improving the tanning effect of the leather sheet, but in the tanning method, the belts wound on the tanning roller are in contact with each other, so that the leather sheet can be contacted with the tanning liquid only at the side surface, the area of the leather sheet absorbing the tanning liquid is limited, the leather sheet cannot be uniformly contacted with the tanning liquid, and the tanning effect is reduced; on the other hand, the tension of the leather fixed on the belt is fixed, and the tension of the leather in the tanning liquid cannot be adjusted, so that the tanning effect is influenced; because the leather sheet is directly placed on the belt and is tightly attached to the belt, the leather sheet is possibly adhered to the belt during tanning, and the leather sheet is possibly torn due to adhesion to the belt when the belt is taken out of the tanning roller; meanwhile, because the leather is soaked in the tanning liquid when the leather is discharged, a large amount of tanning liquid is retained in the discharged leather, and the dosage of liquid medicine used in the subsequent treatment process is increased; as another example, patent document 2 discloses a processing technology of a washable garment, in the tanning technology, a first hand winding wheel 6 and a second winding wheel 7 are provided, and a fur skin is tensioned and arranged on the two hand winding wheels, after the fur skin 61 is led out from the first winding wheel 6, the stirring mechanism 5 is pushed by the electric push rod 4 to go deep into the stirring frame 2, and the fur skin 61 is tanned by the stirring mechanism 5, but the fur skin can only be subjected to single stirring and tanning by the stirring mechanism 5, the tanning time is short, the fur skin 61 cannot be sufficiently tanned, and the fur skin fixed between the two hand winding wheels is a fur skin which can only tanne a fur skin with a certain length and a complete size, and the leather processing range is narrow; as another patent document 3, it discloses a raw hide processing process, which achieves the purpose of shortening the processing process by fixedly disposing raw hides in a telescopic frame to fully spread the hides when performing the corresponding processing process, facilitating full contact of chemicals to the surface of the hides, however, the telescopic frame is used in a dedicated bowl-shaped container 20, and its function is only to enable the hides to be fully spread, and it does not specifically disclose the specific working process of the telescopic frame, nor can those skilled in the art determine the specific driving manner thereof, etc.
