Disclosed are a continuous mercerizing machine for braids and a processing method thereof. The mercerizing machine is composed of an alkali steeping reaction area, an alkali extraction area, a reflux dealkalization area and a baking area in sequence, wherein a retractable roller is used to control the tensile stress of fiber braids in the alkali steeping reaction area, the stepped reverse-rinsing of a dealkalization groove is used in the reflux dealkalization area, a strong alkali liquid, a weak alkali liquid and hot water are successively used to remove the alkali liquid carried by the fiber braids, and a hot air baking machine is used to bake the fibers in a baking system. The mercerizing machine achieves continuous mercerizd production of fiber braids, provides an equipment foundation for the industrialized application of fiber mercerizing, and at the same time has the features of a large yield, simple operation, saving of water resources, reduced sewage discharge and high mercerizing quality.

Disclosed are a process for mercerizing cotton strips and a mercerization device therefor, belonging to the technical field of textiles. The process is as follows: a. pre-treatment of the cotton strips: wetting the cotton strips, and dewatering or wringing, so as to prepare wet cotton strips having a certain liquid loading; b. reeling of the cotton strips: reeling the wet cotton strips on a hank reeling machine, and fixing the cotton strips with tie bands; c. coating: coating the tied cotton strips with a wrapper, such that the cotton strips are integrated with the wrapper; d. mercerization: mercerizing same by concentrated spraying and instant squeezing. The cotton strips are effectively mercerized by the wetting of the cotton strips and the addition of powerful and concentrated spraying and instant squeezing, such that the base loading on the cotton strips is always under control, thereby preventing the cotton strips from being dissolved due to over-swelling and solving the problem that the cotton strips cannot be mercerized in an untwisted state. The mercerized cotton strips are glossy and bright, are fluffy to the touch, and have a 20-30% increase in the colour yield of dyeing.

Disclosed is a processing unit for cellulose fibre mercerization, relating to the dyeing and finishing field. The processing unit comprises one squeezing roller (1), two drawing rollers (2, 4), a base-spraying device and a water-spraying device, with the squeezing roller (1) positioned at the side of and above either one of the drawing rollers (2, 4), and moving in the opposite direction to that of the drawing rollers (2, 4). The base-spraying device is positioned on the press-in port of the mercerization material at the interface between the squeezing roller (1) and the drawing rollers (2, 4), and the water-spraying device is near the mercerized material. The processing unit for cellulose fibre mercerization of the present invention effectively mercerizes the cellulose fibres by concentrated spraying and instant squeezing, such that the base loading on the fibres is always under control, which prevents the fibres from being dissolved due to over-swelling and solves the problem that mercerization cannot be carried out when the cellulose fibres are untwisted.

The present invention relates to an environmentally-friendly textile process and device. A great deal of waste water and waste lye is generated in a mercerization procedure of mercerized yarn. The technical solution provided by the present invention is as follows: room-temperature rinsing waste water is used as a middle-temperature water supply, middle-temperature rinsing waste water is used as a high-temperature water supply, a condensed fluid separated from high-temperature rinsing waste water through a lye separator is added to a room-temperature water supply, the separated condensed lye is recycled as mercerizer lye after the alkali content is adjusted, hot water produced by the lye separator is used for heating the high-temperature water supply and the middle-temperature water supply through a heat exchanger. The present invention achieves zero discharge, realizes energy recovery, and has beneficial effects such as a simple apparatus, simple operation, and low costs.
