Abstract
The pretreatment of silk fibre is degumming through stirring in degumming container containing degumming liquid at 40-80 deg.c and the degumming liquid consists of sodium hydroxide 1-3 portions, whitening agent 0.5-1.5 portions, and water 94.5-98.5 portions. Non-woven fabric of the treated silk is non-toxic, stimulationless, white, soft, elastic, washable and excellent in warming property and it consists of protein fibre containing 18 kinds of amino acids and has skin care effect.
Description
The invention relates to a kind of pretreating process and goods thereof of natural fabric, more particularly about a kind of pretreating process and goods thereof of cocoon fiber.
Real silk, particularly coming unstuck of silk fiber is a problem that is worth research to those skilled in the art always, the mono bath that discloses a kind of silk in Chinese patent application 90100855 is come unstuck and discoloration method, the degumming agent of its use also contains other surfactant of 10～55% except that containing 1～4% paraffin sulfonate, generally speaking these surfactants are high molecular polymers.
Research according to modern science, as far back as 1960's, the Japan scientist is to the cotton analysis and research of silk, think that the important composition of forming the silk cotton is silk many peptides (SilkPolypeptide), have another name called a peptide, its molecular weight height, be water-soluble substances, and further analyze consisting of of peptide of silk 18 kinds of amino acid useful to human body are arranged approximately, the cotton contact very easily with human body skin of silk is absorbed, serine in the good health care effect, particularly component is played in nutrition that can skin care, lysine, arginine, aspartic acid, glutamic acid and histidine all are people's skin, the nutrient that hair etc. are necessary.
The health-care function of silk cotton also is to utilize the ultra violet radiation treatment skin disease of silk fiber, example is arranged: the silkworm cotton of drying with sunshine, because raw material (particularly butyric acid) has absorbed ultraviolet ray, carries out moisture absorption when wearing or cover, radiation can reach sterilization gradually simultaneously.
For skin; moisture remained on 10～20% o'clock in the cuticula; skin anxiety and high resilience; it is comparatively ideal state; this is also very important to the infant; the cuticula of skin possesses natural damping factor; and it is by amino acids; pyrrolidones carbonic acid; lactate; urea; carbohydrate; organic acid; materials such as polypeptide are formed; wherein important composition also has polypeptide (silk peptide); so it can be natural damping factor; reason is the silk-fibroin of solubility; the plain water-based scope of numerous polarity is arranged on its polypeptide chain; make that moisture content is passed to horny layer of epidermis and the water content in the skin is adapted in the body; make skin flexible; smooth and soft; not only and the silk-fibroin of solubility through test to the no abnormal stimulation allergic phenomena of skin, leucine and histidine can also play very remarkable result to skin wound healing in its component, can protect the skin exposed parts not chap; crowfoot cracks etc.
Studies have shown that the silk cotton can also suppress melanin generation in the skin effectively, can keep skin delicate, because the melanin in the skin forms mechanism, be mainly derived from the angle protein tyrosine in forming, but and the activity of silk peptide restraint of tyrosinase and then suppresses the generation of dermal melanin effectively.
One of purpose of the present invention provides a kind of pretreating process of cocoon fiber.
Two of purpose of the present invention provides a kind of through pretreated cocoon fiber goods.
Three of purpose of the present invention provides the cocoon fiber bonded fabric product that a kind of water acupuncture manipulation produces.
These and other objects of the present invention will further embody by following description and detailed description.
In the present invention, the pretreating process of cocoon fiber comprise come unstuck, step such as oven dry, wherein the prescription of degumming baths is: caustic soda 1～3 weight portion, brightening agent 0.5～1.5 weight portion, water 94.5～98.5 weight portions.Further, at first sleave is placed in the container that comes unstuck, puts into degumming baths, stirring and temperature is come unstuck when being 40～80 ℃, to thread in matrix originally taken off till.To take off real silk rinsing in clear water of glue then, to washings PH=7, dehydration (80%) then, oven dry.
Especially, when being used as nonwoven fabric, pretreated cocoon fiber can adopt following steps if need with of the present invention:
At first press as mentioned above, sleave or inferior silk are come unstuck, dry, make keen-witted and capable, and then make the long 6～10cm of tow with the opener shredding, use the carding machine combing then, making it does not have caking, combing is between 10～30 ℃ of temperature, and 30～80% of humidity are carried out, and adopts air-cooled then or the lapping of air lay method.
Real silk net after becoming to net can be by the typing of spray glue, and and then hot pressing rolling is come according to making 25～200g/m
2Real silk cotten non-woven cloth.
Real silk net after becoming to net also can be by acupuncture, and the quilt mode of rolling then comes according to making 80～300g/m
2Real silk cotten non-woven cloth.
Real silk net after becoming to net also can comprise by the typing of water thorn uses water jets under high pressure with the fine water flow jet fiber web of high speed, and simultaneously, the interspersed double action of bounce-back through holder lace curtaining water column makes fiber tangle mutually according to making 20～300g/m again
2Real silk cotten non-woven cloth.
Real silk net after becoming to net also can come according to making 60～200g/m by the mode of impregnation, hot pressing, rolling
2Real silk cotten non-woven cloth, at this, impregnation adopts one to soak three and roll, pressure is 6～8Kg, temperature is 140～170 ℃, the temperature of hot pressing is 100～180 ℃, pressure is 3～8Kg.
In the present invention, the glue that impregnation and spray glue adopt is conventional market adhesive on sale, is applied on the nonwoven fabric after itself and water are mixed by 1: 2～5, and amount of application based on nonwoven fabric heavily generally can be 5～15%.
In the present invention, all equipment is that textile industry uses always, further, can adopt commercially available cotton spinning, silk spinning and pre-processing device.
Especially, in the present invention, alleged real silk can be pure silk cocoon silk, tussah silk, wild silk yarn, can be a kind of separately, also can be its mixture, can certainly use the mixture of real silk and cotton and natural fabric or synthetic fiber.What optimum the present invention used tells, cuts mouth, mouse mouth cocoon, husks, macula lutea and yellowish-white recotti, pin slag etc. as remaining sleave and leftover bits and pieces behind the silkworm firefly silk, particularly silkworm firefly filature as length.
Nontoxic, non-stimulated with the prepared bonded fabric product that goes out of method of the present invention to human body, by mass area ratio can be divided into 20,30,60,90,120,150,200,250,300g/m
2Etc. several, tasteless, the no spot of appearance white, variegated, soft, warmth retention property is fabulous, flexible, no interlayer adhesion after the rolling does not have damaged.The nonwoven fabric that the water acupuncture manipulation produces has intensity height, high-hygroscopicity and gas permeability, be difficult for walking hair, soft, drapability good, particularly adhesive-free is free from environmental pollution.For silk cocoon silk content for the made nonwoven fabric of silk cocoon silk greater than 98%, the ultimate strength warp-wise is not less than 30N, broadwise is not less than 6.5N, the elongation at break warp-wise is not more than 11%, broadwise is not more than 13%, bursting strength is not less than 500kpa, and the wash resistant number of times is not less than 12 times, and Air permenbility is greater than 1.0m
