What calls spinning stick non-woven cloth? What is the difference with non-woven fabric?

Affiliation: spunbonded non-woven fabric is a kind of non-woven fabric.

Non-woven fabric is a kind of fabric that does not need to be spun. It is just a directional or random support of short fibers or filaments to form a fiber net structure, and then reinforced by mechanical, thermal bonding or chemical methods. Simply put: it's not made up of strands of yarn interwoven and knitted together, but fibers glued together physically, so when you reach for the adhesive scale inside your clothes, you'll find that there's no thread to pull out. Nonwovens break through the traditional textile principle, and has a short process, production speed, high yield, low cost, wide use, raw material sources and so on.

Its main uses can be roughly divided into:

(1) Medical and health cloth: surgical clothes, protective clothing, disinfectant bags, masks, diapers, women's sanitary napkins, etc.;

(2) home decoration cloth: wall cloth, tablecloth, bed sheet, bedspread, etc.;

(3) with cloth: lining, fusing lining, floc, shaping cotton, all kinds of synthetic leather bottom cloth;

(4) Industrial cloth: filter material, insulation material, cement packaging bag, geotextile, coated cloth, etc.;

(5) Agricultural cloth: crop protection cloth, seedling raising cloth, irrigation cloth, insulation curtain, etc.;

(6) Others: space cotton, heat preservation and sound insulation materials, linoleum, cigarette filters, tea bags, etc.

Classification of non-woven fabrics:

Spunlaced non-woven fabric: spunlaced process is the high pressure micro water jet to a layer or multi-layer fiber net, so that the fiber tangled together, so that the fiber net can be reinforced and have a certain strength.

Two, thermal bonding non-woven fabric: thermal bonding non-woven fabric refers to the addition of fibrous or powdery hot-melt bonding reinforcement material in the fiber net, fiber net after heating melting cooling reinforcement into cloth.

Three, pulp air flow into the net of non-woven fabric: air flow into the net of non-woven fabric can also be called dust-free paper, dry paper non-woven fabric. It is the use of air flow into the net technology of wood pulp fiberboard loose into a single fiber state, and then use air flow method to make the fiber agglutinate on the net curtain, fiber net and then reinforce into cloth.

Four, wet non-woven fabric: wet non-woven fabric is placed in the water medium of fiber raw materials loose into a single fiber, at the same time to make different fiber raw materials mixed, made of fiber suspension slurry, suspension slurry transported to the network mechanism, fiber in the wet state into a network and then reinforced into cloth.

Five, spunbond non-woven fabric: spunbond non-woven fabric is in the polymer has been extruded and stretched to form a continuous filament, filament laid into a net, fiber net after its own bonding, thermal bonding, chemical bonding or mechanical reinforcement method, so that the fiber net into non-woven fabric.

Six, melt-blown non-woven fabric: the process of melt-blown non-woven fabric: polymer feeding -- melting extrusion -- fiber formation -- fiber cooling -- into a net -- reinforcement into cloth.

Seven, needle-punched non-woven fabric: needle-punched non-woven fabric is a kind of dry non-woven fabric, needle-punched non-woven fabric is the use of needle puncture effect, the fluffy fiber net reinforcement into cloth.

Eight, woven non-woven fabric: woven non-woven fabric is a dry non-woven fabric, woven is the use of warp knitting coil structure of fiber net, yarn layer, non-textile materials (such as plastic sheets, plastic thin metal foil, etc.) or their combination to reinforce, to make non-woven fabric.
