Abstract

The present invention discloses pretreatment technology of natural silk fiber, which comprises the steps of degumming, drying, etc., wherein degumming liquid has the formulation of 1 to 3 weight shares of caustic soda, 0.5 to 1.5 weight shares of whitening agents and 94.5 to 98.5 weight shares of water. Floss silk is first placed in a degumming container, degumming liquid is filled, and the floss silk is stirred and degummed at the temperature of 40 to 80 DEG C until the glue in the floss silk is fundamentally degummed. A nonwoven cloth product has the advantages of innocuity and no stimulation to a human body, white and tasteless appearance, no spot, soft hand feeling, elasticity, washing and excellent heat insulation performance. Due to the fact that the nonwoven cloth product is composed of protein fiber, and therefore, the nonwoven cloth product contains 18 kinds of amino acid components, and has a protective function to the skin of a human body.

Description

The pretreating process of cocoon fiber and goods thereof

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: with sun-cured silk cotton, 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 is possessing 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 still 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 wise man in vain, 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 skin melanocyte 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.

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, and combing is between 10～30 ℃ of temperature, 30～80% of humidity are carried out, and adopt 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 perverse by pin, 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 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, with itself and water by 1: be applied on the nonwoven fabric after the 2-5 mixing, 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 60,90,120,150,200g/m ²Etc. several, appearance white is tasteless, no spot, variegated, soft, warmth retention property is fabulous, flexible, no interlayer adhesion after the rolling does not have damaged.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 ³/ m ², s.

Real silk cotten non-woven cloth of the present invention selects for use real silk to do raw material, but not only cutting but also can wash is fibrous by true protein, contains 18 seed amino acid compositions, and human body skin is had protective effect.Have loose, the soft natural true qualities of pure silk, and can wash and comply with the need cutting, can replace metal wool and various nonwoven fabric of synthetic fibre, also can make wallpaper, carpet etc.Be the best article of resisting cold, warming, ventilative, the moisture absorption.

Below further specify the present invention by specific embodiment, embodiment only be used for the explanation and can not limit the scope of the invention.If not refer in particular in the present invention, all percentage, part all is weight percentage weight portion.
