Abstract
The invention relates to a method for processing excimer laser irradiation, which is used for modifying textile surface, which comprises following steps: firstly, placing an object which will be processed, secondly, regulating the distance between the excimer laser irradiation and textile, thirdly, regulating the pressure strength in an excimer laser irradiation processing chamber, fourthly, processing by irradiating, and irradiating the object which will be processed for 0.1-0.5min. The method of the invention for modifying the surface of the textile is highly effective and convenient. The hydrophilicity of the textile surface which is modified is greatly increased, the appearance dying depth is also improved, and the influence for warp and weft breaking strength is not big.
Description
Technical field
The invention belongs to the textile surface modifying field, particularly relate to method and device thereof that a kind of quasi-molecule ultraviolet source is handled textile surface modifying.
Background technology
The clearer production technology of anhydrous dyeing and finishing is the problem that people explore for a long time always, also is the idealized model of 21 century weaving processing.The history in existing about 30 years of the anhydrous activation processing technical research of textile surface of developing at present, the method that adopts has conventional incoherence ultraviolet source irradiation (low pressure, middle and high pressure mercury lamp, xenon arc lamp etc.), Excimer UV laser irradiation and plasma glow discharge.The ultraviolet light light efficiency of conventional incoherence ultraviolet source is low, and a little less than the light intensity, process velocity is too slow, does not have very big practical value; Excimer UV laser is because itself technical restriction also is difficult to realize industrialization in the recent period on textile treatment; Plasma glow discharge can be carried out good treatment to textiles, but its equipment and processing cost are all very high.
Quasi-molecule ultraviolet source is a kind of 20 years historical novel high-strength incoherence monochromatic ultraviolet light sources that only have, compare with the ultraviolet source of routine, the intensity of quasi-molecule ultraviolet source is the former tens of times, emission spectrum is that bandwidth is the narrow bands of a spectrum of 10nm, and the textiles serialization that can be made into high-efficiency and low-cost does not have water treatment facilities.Compare with the textile surface treatment technology of Excimer UV laser and plasma glow discharge, the cost of its processing and technology expend greatly and reduce.Therefore this technology is a kind of cleaning, wide, quick, the energy-conservation state-of-the art technology processing method of adaptation.
Wool is a kind of good natural fabric, yet the outermost epidermal area of its surperficial scale structure and its cuticle cell is rich in C
21Be main aliphatic acid, give the wool surface with hydrophobicity; The appearance cortex is rich in cystine, and the covalent cross-linking of the disulfide bond of cystine between the big molecule of wool makes the density on wool surface increase, and this has influenced wool dyeing and finishing chemical process to a certain extent and has taken performance.Therefore successful surface modification not only can be improved the surface property of wool fabric, also is the effective way that improves wool dyeing and finishing crudy.
Aramid fiber is a kind of high-performance fiber, characteristics such as, resistance to chemical attack heat-resisting, fire-retardant and be widely used in space flight and military field with it, but its fiber surface polar group content is lower, the macromolecular end carbonyl of fiber influences its infiltration to resin, adhesive property in fiber surface enrichment to some extent simultaneously.Therefore be necessary fiber is carried out surface modification, to improve its application performance and field.
Summary of the invention
Technical problem to be solved by this invention provides a kind of quasi-molecule ultraviolet source treatment method and device thereof that is used for textile surface modifying, to improve the surface property of fabric, enlarges its Application Areas.
Technical scheme
