Embodiment Construction
[0027] The technical solutions in the present invention are clearly and completely described below in conjunction with the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0028] A preparation method for UV-resistant printing and dyeing cloth, comprising the following steps:
[0029] Step 1: Singeing the hemp fabric at the burner port of the singeing machine for 2 forward and 2 reverse singes, and extinguishing the fire with steam;
[0030] Step 2: roll the hemp fabric rolling working solution A at room temperature of 25°C and stack it for 20-25 hours. The working solution A contains: 10g / L of compound desizing enzyme and 2g / L of penetrating agent;
[0031] Step 3: Wash the linen fabric at 85-90°C for 2-3 grids, roll the working solution B, and steam for 2-3 minutes. The temperature of the steamer is 9...

The invention relates to a preparation method for an ultraviolet-proof dyeing cloth and belongs to the field of bast fiber fabric after-treatment. The technological process is as follows: singeing, enzyme cooling reactor, low-temperature enzyme oxygen bleaching, steam whitening, ultraviolet-proof waterproof treatment, baking, air soft finishing and shrink-proof treatment. For solving the technical problems in development of ultraviolet-proof waterproof bleaching fiber dyeing cloth, the invention strives to make technological breakthrough at the aspects of fabric pretreatment, ultraviolet-proof treatment, water-proof agent, bleaching color fastness, and the like, settles the contradiction between thread count and ultraviolet-proof effect of summer clothing material and the contradiction between ultraviolet-proof treatment and waterproof settlement, solves the problem of bleaching color fastness and the problem of material wearing comfort, maintains the original excellent characteristics and overcomes the defects.
Description
technical field [0001] The invention belongs to the field of post-treatment of hemp fabrics, and in particular relates to a preparation method of an ultraviolet-proof printing and dyeing cloth. Background technique [0002] With the development of industry, industrial waste gas leads to atmospheric pollution and ozone layer destruction. In the past, it was considered as a sunbathing for the pursuit of health, but now it has become a ruthless "sun killer" that threatens human health. The ozone layer is destroyed, the ultraviolet transmittance increases, and the probability of human beings suffering from skin cancer increases. Some experts predict that by the end of this century, the incidence of skin cancer will leap to the top of various diseases and become the number one killer of human beings. Therefore, people are vigorously researching ultraviolet radiation protection products, and now the sales of anti-ultraviolet cosmetics and daily necessities are increasing sharply...
