Definitions

  • the invention relates to the technical field of wipes, and in particular to a wipe with abrasion resistance and anti-fuzzing surface for personal care and infant care and a manufacturing method thereof.
  • Wipes are often used in daily life, such as when parents change diapers for babies, or when dining in a restaurant, or when putting on make-up and skin care. Because the wipes are quite convenient to carry and store, and are convenient to use, they are popular among consumers. Therefore, wipes are more and more widely used in personal care and infant care.
  • the wipes can be spunlace non-woven products or spunbonded non-woven products. More traditional cloth wipes have convenient production methods, low prices, and can be used dry or wet.
  • wood pulp is often added to the wipe to improve the moisture absorption and decontamination ability of the wipe.
  • the wood pulp fibers are natural short fibers. The fibers are short and are not affected by temperature and are not easy to be consolidated together. They are only fixed by spunbonding or spunlace processes. When in use, the wood pulp will be rubbed several times. Short fibers are easy to fall off, causing hair loss, which affects service life.
  • the purpose of the present invention is to provide a wipe and its manufacturing method for preventing surface fluffing and linting, and to overcome the defects of existing products and production methods.
  • a wiper the upper and lower layers of the wiper are meltblown fiber webs, and the middle layer is a wood pulp fiber web, wherein the surface of the meltblown fiber web and the inside of the meltblown fiber web adjacent to the surface are both An adhesive is attached, and the melt-blown fibers of the melt-blown fiber web are interspersed in the wood pulp fiber web.

  • the difference between the melting point of the high melting point resin and the low melting point resin is ⁇ 20°C.
  • the fiber with low melting point resin on the fiber surface is a single-component melt-blown fiber, a two-component melt-blown fiber or a mixture of the two.
  • the two-component melt-blown fiber is a two-component sheath-core melt-blown fiber, a two-component orange petal-type melt-blown fiber or a two-component side-by-side melt-blown fiber.

  • the weight of the wood pulp fiber web accounts for more than 50% of the total weight of the wipe.
  • the percentage of the weight of the wood pulp fiber web to the total weight of the wipe is 65% to 80%.
  • the wood pulp fiber web contains hot melt adhesive material.
  • the hot-melt adhesive material is low-melting polyester fiber, ES short fiber, two-component spunbond long fiber or a mixture thereof.
  • a method for manufacturing wipes includes the following steps:
  • thermoplastic resin is heated and melted, and the melt stream of the thermoplastic resin sprayed from the spinneret is blown into fiber bundles with a fiber diameter of less than 10um by using high temperature and high-speed hot air flow.
  • the airflow forms a meltblown fiber web, and it intersects with the two sides of the wood pulp fiber web to form a multi-layer structure fiber web with a meltblown fiber web on both sides and a wood pulp fiber web in the middle;
  • the multi-layer structure fiber web is consolidated by the heating device to form the upper and lower layers of meltblown fiber web, the middle layer is a wipe of wood pulp fiber web, and the meltblown fiber Adhesive is attached to the surface of the mesh and the inside of the meltblown fiber mesh adjacent to the surface.
  • the two thermoplastic resins whose melting point difference is greater than or equal to 20°C are heated and melted, and the thin stream of the thermoplastic resin melt sprayed from the spinneret is blown into fibers by using high temperature and high-speed hot air flow.
  • Fiber bundles with a diameter of less than 10um are accompanied by hot air flow to form a melt-blown fiber web, wherein the melt-blown fiber web contains fibers with a high melting point resin on the fiber surface, fibers with a low melting point resin on the fiber surface, or a blended fiber of both.
  • the spinneret contains two-component spinneret holes.
  • the two-component spinneret holes on the spinneret are of skin-core type, orange petal type or side-by-side type.
  • the heating device is a hot air oven, a hot roll or a combination of both.
  • the wood pulp is loosened and dispersed by an opening roller, mixed with the hot-melt adhesive material, and then formed into a wood pulp fiber web containing the hot-melt adhesive material through a nozzle under the action of an auxiliary airflow.
  • the wiper manufacturing method of the invention can be applied to make the wiper of the invention. Because the meltblown fiber web of the wiper of the invention has small fiber denier and densely arranged, it can effectively prevent the wood in the middle layer. The fall of short pulp fibers.
  • adhesive is attached to the interior and surface of the meltblown fiber web, so that the meltblown fiber web forms a layer of adhesive film, so that the wipes can prevent the surface meltblown fibers from being exposed to external forces due to multiple frictions.
  • the phenomenon of fluffing and fluffing caused by the mutual separation and bonding under the action also further prevents the short fibers of the wood pulp in the middle layer from falling out, and the problem of "fluffing" during use and unclean wiping.

Abstract

L'invention concerne une lingette. Des couches supérieure et inférieure de la lingette sont des bandes de fibres de fusion-soufflage (13, 14), et une couche intermédiaire de celles-ci est une bande de fibres de pâte de bois (12), un adhésif étant fixé aux surfaces des bandes de fibres de fusion-soufflage (13, 14) et à leurs parties intérieures qui sont adjacentes aux surfaces, et la fibre de fusion-soufflage des bandes de fibres de fusion-soufflage (13, 14) pénétrant dans la bande de fibres de pâte de bois (12). L'invention concerne également un procédé de fabrication de la lingette. Ledit procédé peut être utilisé pour la fabrication d'une lingette absorbant l'eau. Comme l'adhésif est fixé aux parties intérieures et aux surfaces des bandes de fibres de fusion-soufflage, les bandes de fibres de fusion-soufflage forment une couche de film adhésif. Par conséquent, lorsque la lingette est utilisée, des phénomènes d'aspect gonflant et de boulochage sont empêchés, de tels phénomènes étant provoqués par un désengagement mutuel de la cimentation entre les fibres de fusion-soufflage sous l'action d'une force externe puisque les fibres de fusion-soufflage de surface sont soumises à de multiples instances de frottement.
