A kind of kapok textiles and process technology thereof with natural anti-mite function
Technical field
The invention belongs to technical field of textile processing, be specifically related to a kind of process technology with the natural textiles that drives mite function, particularly relate to a kind of process technology with the natural kapok textiles that drives mite function.
Background technology
Acarid is a kind of arthropod, and build is small, and generally in about 0.1~0.5mm, people's naked eyes cannot see, the dead skin coming off by human body and sweat, grease are made a living.Acarid usually survives in pillow, mattress, coverlet, quilt cover, bed clothes, sofa, spring mattress, carpet, woollen blanket, the toy that becomes mildewed, fur, mat etc. and locates.Interrelated data demonstration, the quilt not shining for three months, has 6,000,000 of acarids above it.The secretion of acarid, metabolin are strong sensitization sources, can cause the diseases such as allergic asthma, allergic rhinitis and allergic dermatitis, very harmful to children and anaphylaxis crowd.Along with the raising of people's living standard, anti-mite function textile is more and more subject to consumer's favor.Because anti-mite effect characterizes with driving mite rate conventionally, be also known as and drive mite function textile.
At present, the anti-mite of selling on market or drive mite textiles and mainly contain three classes: the one, adopt anti-mite finishing agent to carry out rear arrangement processing to fabric and obtain drive mite fabric; The 2nd, mite-proof medicine is joined in fibre-forming polymer, make the goods of anti-mite fiber through spinning; The 3rd, by superfine fibre and the highly dense physical anti-mite fabric making of weaving, this method can not repellent or is killed acarid, only depends on braiding tightness prevent the intrusion of acarid or pass through, and plays the effect of isolation acarid.Above method all has limitation to a certain degree.The anti-mite material adopting in first and second kind of method is all chemical products, not only its manufacture has harm to environment, if and in using on textiles residual anti-mite chemicals exceed standard and also can bring potential safety hazard to human body, and second method is only only applicable to chemical fibre.The third method is because textiles in use needs experience wearing and tearing, washing, and yarn attenuates the hole in textiles is increased, thereby progressively loses anti-mite effect.
Bombax cotton is the fruit fiber of several plant in Malvales Bombacaceae, has high hollow, the outstanding feature such as light, thin, soft, is a kind of new type natural fiber of developing of needing.Simultaneously, bombax cotton has the well natural specific functions such as mite of driving, press GB/T24253-2009 " the anti-mite performance evaluation of textiles " method test, the mite rate of driving of natural kawo fiber generally all more than 95%, is driven when mite rate is greater than 60% and is assert that sample has anti-mite effect.Kapok textiles, can absorbing carbon dioxide and prevent erosion due to this fiber production process, environment is had everything to gain and nothing to lose, in use to human body without negative effect, be real green low-carbon textiles.
But, we study discovery, current textile process technology to bombax cotton to drive mite functional lesion very large, dyeing and finishing processing method resembles decocting herb, bombax cotton after being processed by dyeing and finishing becomes the Chinese medicine slag through " decoction ", makes the mite rate of driving of existing kapok BLENDED FABRIC generally less than 50%; And containing the true qualities yarn of kapok 20% or the mite rate of driving of grey cloth all more than 80%, illustrate spins weave that processing do not affect kapok drive mite effect; Bombax cotton 40 minutes rear-guard mite rates of high-temperature baking in the gaseous medium of 140 DEG C are not almost lost, the conventional dry finishing technique that textiles is described to bombax cotton to drive mite function effect little.Therefore, we research and develop following new process technology, and this technology should not damaged the natural function of bombax cotton, can meet contemporary consumer to healthy, green, with the get along pursuit of textiles of natural harmony.
Summary of the invention
Technical problem to be solved by this invention is to provide natural mite function textile and the process technology thereof of driving of a kind of kapok, and this textile product has the natural mite function of driving, and can make up defect and the deficiency of prior art, meets the demands of production and living.
In order to solve the problems of the technologies described above, the invention provides a kind of kapok textiles with natural anti-mite function, it is characterized in that, comprise natural kawo fiber 10%~90% and other fiber 10%~90% by weight percentage; Described other fiber is any one or a few in other natural fabric and chemical fibre.
Preferably, described other fiber is any one or a few in cotton fiber, viscose, bamboo oar fiber, wool, cashmere fiber, ramee, linen fibre, hemp, terylene, polyamide fibre, spandex and chitin fiber.
Preferably, when described kapok textiles is non-white, other fiber or chemical fibre are colored fibre.
The present invention also provides the process technology of the above-mentioned kapok textiles with natural anti-mite function, it is characterized in that, comprises the steps:
Step 1): by after natural kawo fiber and the mixing of other fiber opening, adopt RING SPINNING or Revolving cup spinning equipment to make kapok blended yarn in proportion;
Step 2): by step 1) the kapok blended yarn that makes is pure knits or make knitted fabric or woven fabric with other yarns interwoven;
Step 3): by step 2) knitted fabric that makes or woven fabric be successively through kapok grey cloth, kiering or soap, after the processing technology of softener arrangement, dehydration, oven dry, tentering setting, make product.
Preferably, described step 1) in kapok blended yarn coloured yarn that is non-white time, other fiber is colored fibre.
Preferably, described step 3) in the technological parameter of kiering be: concentration of lye is 0.1-30g/L, and temperature is 10-100 DEG C, and duration is 10-250min.
Preferably, described step 3) in the technological parameter of soaping be: the temperature of soaping is 10-60 DEG C, and the duration of soaping is 10-100min.
The mite rate of driving of natural kawo fiber provided by the invention is more than 95%; Containing the yarn of kapok 20% or the mite rate of driving of grey cloth, more than 80%, what spinning weaved that processing do not affect kapok drives mite effect; Bombax cotton 40 minutes rear-guard mite rates of high-temperature baking in the gaseous medium of 140 DEG C are not almost lost, the conventional dry finishing technique of textiles to bombax cotton to drive mite function effect little.
The invention has the beneficial effects as follows: (1) does not add chemical anti-mite reagent and just can realize the anti-mite function of textiles, and Product Green environmental protection, without the side effect of chemicals; (2) the high hollow structure of bombax cotton and surface texture make fabric contain a lot of still airs, and the feel of kapok product is fine and smooth, soft, fluffy, good warmth retention effect; (3) after, arrange processing and adopt low temperature, low acid base concentration, short flow processing, can significantly reduce the resource consumptions such as water, electricity and gas chemicals.
