Later-stage processing method of fabric and special equipment thereof

Abstract

The invention discloses a later-stage processing method of fabric and special equipment thereof. The special equipment comprises one or a plurality of cylinders, an expander and an ironing machine which are arranged in sequence along the running direction of the fabric, wherein an inlet device and an outlet device are arranged at the inlet and outlet of each cylinder respectively; each inlet device and each outlet device respectively comprise an upper pressurized water roll, a lower pressurized water roll and a power device used for driving the pressurized water rolls; a sponge water absorbing roll is adopted as the pressurized water roll of the final outlet device; the ironing machine comprises a first rotary drum and a second rotary drum the gear ratios of which can be adjusted; and the expander takes the shape of an inverted trapezoid, and is arranged on a conveyer belt at the feeding port of the first rotary drum of the ironing machine. The special equipment disclosed by the invention can be used for simultaneously processing elastic fabric and non-elastic fabric, and the processed elastic fabric has flat and smooth surface and good elasticity.

Problems solved by technology

[0002] In the current dyeing and finishing equipment, the methods and machines usually used are suitable for dyeing and finishing of non-elastic fabrics. When finishing elastic fabrics, especially high-elastic fabrics, it includes dyeing, washing, drying and setting. , often can not be handled: because warp elastic fabric or two-way warp and weft elastic fabric will be deformed after entering water, the size will be reduced, and the size and elasticity cannot be fixed when drying; In the existing technology, rope-like cloth feeding is generally used, that is, the elastic cloth is twisted into a rope shape and sent into the machine. However, if rope-like cloth feeding is used for dyeing, when the fabric is opened, the fabric must be flattened, resulting in uneven dyeing; The elastic force in the weft direction cannot be controlled, and the weft direction cannot enter the drying tunnel, and after the rope-like knot, the weft direction size can no longer be estimated; and it may no longer be possible to open and make flat

The existing technology and equipment all use the method of warp and weft two-way force traction to make the fabric flat. Using this method must face the problem of uncontrollable tension, because first, the weft shrinkage rate of the elastic fabric after water entry cannot be predicted, so it cannot be adjusted. Determine the tensile strength and size of the weft direction; the second is that the warp direction will become shorter, because all the existing downstream equipment is in the form of tension traction. When the fabric is conveyed, the fabric is also completely pulled apart. Or other drying methods, the fabric is shaped and no longer elastic. That is to say, if the size of the fabric is fixed by increasing the tension in the warp and weft directions, then the elasticity will not be controlled, and the elasticity of the fabric will be damaged.
