Description
Technical field:
The present invention relates to environmental protection skin care product scope, be specifically related to the manufacture method of subsides skin class health that a kind of environment-friendly type silk fiber is raw material, health care and protection nonwoven fabric.
Background technology:
Silk belongs to natural protein fibre, is rich in 18 seed amino acids, and its composition forms very similar to the skin of human body.Silk has the advantages that other fiber does not possess: silk has outstanding humidity absorption and release, moisture and sweat vapour that skin comes out can be absorbed, then be discharged in extraneous air, assist the physiological regulatory action of skin, eliminate gloomy humidity, make people still feel Clean and comfortable in sultry weather; Because of at the simultaneously stability of humidity absorption and release or distribute heat, temperature can also be relaxed and sharply change the impact brought to skin; Compared with synthetic fiber, the hygroscopicity of silk is very strong, so be not easy to produce electrostatic, the discomfort such as stimulation, dust suction thus avoiding electrostatic to bring.Silk has outstanding high heat insulating ability, and microfibre structure makes silk inside containing large quantity of air, and thus silk is soft, and good springiness is cool in summer and warm in winter.Silk has outstanding flame retardancy, fine can not to soften like that as conjunction when silk meets high temperature, melting, burning, releasing poison gas, be therefore more suitable for the manufacture craft of spunlace non-woven cloth.In addition, even if silk burning also can not be attached on skin.Silk has outstanding fungi-proofing deodorizing effect, and silk is the fiber that bacterium is difficult to grow, and absorbs the effect of pernicious gas, smelly eliminating deodorization in addition.
Subsides skin class (directly contacting with human body skin) health, health care and protection nonwoven fabric are the conventional indispensable daily necessitiess in mankind's daily life.As: the sanitary napkin in disposable sanitary articles, protection pad, baby diaper and diaper, adult-incontinence articles; Extensive wound gauze in medical material, bandage; And the facial mask, wiping face-cloth, makeup removing towel etc. in cosmetic skincare product.Particularly the consumption consumption of sanitary napkin, protection pad, baby diaper and diaper, adult-incontinence articles and mask product, wiping face-cloth, makeup removing towel etc. is quite huge, sphere of consumption extend over the entire globe.
With regard to the manufacturing nonwoven fabric of disposable sanitary articles, mainly contain high hydroscopic resin (SAP), breathable films and non-weaving cloth at present.What wherein directly contact with human body skin is non-weaving cloth, the nonwoven fabric that namely it has often been said.It directly utilizes high polymer section, staple fibre or long filament that fiber is become net by air-flow or machinery, then through water thorn, and acupuncture, or hot rolling is reinforced, and eventually passes the cloth without braiding of Final finishing formation.Have the fibre of softness, ventilative and planar structure, advantage does not produce Soft flocks, tough, durable, silkiness is soft, is also the one of reinforcing material, and also have the sensation of cotton.At present main or based on artificial fibre and chemical fibre for the manufacture of the fibrous raw material of nonwoven fabric, or also have a small amount of product to adopt silk to be raw material.
The currently used technological process control of manufacture of nonwoven fabric mainly contains: water acupuncture manipulation, heat seal, air laid, wet method, spun-bond process, meltblown and needle point method etc.Water jet process be by fine for high pressure water flow jet on one or more layers fiber web, make fiber mutually entangled, thus fibre web reinforced and possesses certain brute force.
Be seen in although existing report and media disclosure or disclosed silk non-woven fabric as with the product ommercialization case such as the sanitary napkin of the direct contact material of human body skin, protection pad, infant's diaper, adult incontinence product, facial mask and face-cloth, but these silk non-woven fabric applied wherein still also exist the hidden danger and the inducement that cause human body skin allergy and worsen contact wound.
Reason is as follows: the first operation that silk fiber is produced is exactly extracted by the silk in silk cocoon, for this reason, first silk cocoon must be carried out unwinding process of coming unstuck.Unwinding object of coming unstuck makes the abundant swelling of the silk gum between silk and is partly dissolved, and reduces or reduce the deadlocked power of silk gum, make silk be easy to dissociation.Cocoon cooking is then the means realizing unwinding object.Unwinding object makes silk be easy to dissociation.
Silkworm weave silk cocoon time, why silk sequentially can be made cocoon layer successively and closely not disorderly, be because the silk gum of silk periphery is mutually deadlocked in turn it; In addition, due to factor impacts such as storage and cocoon dryings during large cocoon results, so that it is very deadlocked, and the deadlocked power between silk is stronger, thus result in silk cocoon adds man-hour silk dissociation difficulty at filature, in the industry also referred to as unwinding difficulty.Data show: containing the silk gum of about 13% ~ 23% in silk.Primary and foremost purpose in silk filature industry manufacturing procedure reduces the deadlocked power between this silk, under current process conditions, utilize the effect of water, heat or some chemical assistants etc., by suitable for the silk gum of silk periphery swelling be partly dissolved, to reduce the deadlocked power between silk, enable silk continuously dissociation successively, this process is exactly cocoon cooking.
The alkali of high level, hydrogen peroxide and chemical assistant must be used in traditional and existing cocoon cooking production technology, silk fiber after unwinding process inevitably exist chemical residue may, this causes the above-mentioned main hidden danger that allergy and wound deterioration occur with skin that is direct body contact.And up to now, silk filature industry manufacture field still fails to propose more pollution-free, clean unwinding technique and scheme.
