The disclosure discloses a positioning laser 3D four-layer air thermal ventilation channel fabric and a method for processing the same. The disclosure is characterized by comprising a closed face cloth layer and a closed bottom cloth layer, wherein the closed face cloth layer comprises face base cloth, a pu environmental-friendly glue layer and a differentiated TPU polyurethane film from top to bottom, the closed bottom cloth layer successively comprises the differentiated TPU polyurethane film, the pu environmental-friendly glue layer and bottom lining cloth from top to bottom, and the face base cloth is provided with laser cutting points for laser visual recognition. During the processing, the closed face cloth layer and the closed bottom cloth layer are prefabricated, then channels on the fabric are glued, and finally patterns and ventilation points are cut by using laser. The disclosure has the advantages that down feathers are replaced with air in the channels, so the fabric of the disclosure is light and has no down feather running phenomenon, the cost is lower, and the air can be collected and freely released and is convenient for storage.

Provides a four-layer structure screen protective film and a manufacturing process thereof, comprising films arranged in sequence, from bottom up: bottom layer release film, single-sided silica gel segmented composite release film, single-sided silica gel hardened practical film, and top layer protective film; composite release film has break lines arranged along length direction, which segment composite release film into pieces; low-viscosity silica gel layer is fixedly arranged on lower surface, whose lower surface is bonded to upper surface of bottom layer release film; lower surface of single-sided silica gel hardened practical film has silica gel layer fixedly arranged, whose lower surface is bonded to composite release film. Being able to move on screen repeatedly during film-adjusting process, avoiding large area of silica gel exposing after whole face of release film is peeled off, thus avoiding from sucking dusts or cilia in air.

Disclosed is an acid-modified flour and a method of making the acid-modified flour. The acid-modified flour is desirably prepared using a dry milling process. A starting flour is combined with a strong acid to form a mixture. The mixture is heated. A neutralizer is added to increase the pH of the mixture. If desired, the mixture can be dried and any agglomerates can be removed. The acid-modified flour can be used as a binder in a slurry for preparing one or more gypsum layers in a gypsum board.

A method for manufacturing metal parts with split ends joined. An end of a metal plate or solid metal rod is split. The length of the incision is adjusted and a smooth split face is formed. A metal plate is secured by pinching both sides with a clamping device, or a solid metal rod is pinched on opposite portions on the periphery with a clamping device. The plate/rod is split longitudinally by slitting or cleaving the plate/rod by pressing a slitting or cleaving punch against the face of one end of the plate/rod. The splitting is advanced by repeating the operation of pressing the punch against the cleft of the splitting. In each splitting operation, the position of the clamping device is moved in advance of the next pressing by a stroke corresponding to the distance from one end of the plate/rod, to the distal end of a split-desired portion.

The present invention relates to a method of producing a coherent growth substrate product formed of man-made vitreous fibres (MMVF), comprising the steps of (vi) providing MMVF; (vii) providing an uncured binder composition; (viii) providing a superabsorbent polymer; (ix) forming a mixture of the MMVF, the uncured binder composition and the superabsorbent polymer; (x) curing the uncured binder composition in the mixture to form the coherent growth substrate product; wherein the uncured binder composition comprises at least one hydrocolloid.

This invention relates to a washable multi-component floor mat. The floor mat contains a textile component and a base component. The textile component and the base component are attached to one another by at least one surface attraction means and at least one edge attachment means. The textile component is designed to be soiled, washed, and re-used, thereby providing ideal end-use applications in areas such as building entryways. The present invention eliminates the need to wash the base component of the floor mat which results in environmental, cost and labor conservation.

A light emitting device can further improve light extraction efficiency. A method of manufacturing such a light emitting device can also prove advantageous. The light emitting device includes a light emitting element, a light-transmissive member which is disposed on a light extracting surface side of the light emitting element, and a reflecting layer disposed on an element bonding surface of the light transmissive member where the light emitting element is disposed and adjacent to the light emitting element. The light-transmissive member, in a plan view, has a planar dimension greater than the light extracting surface of the light emitting element.

A system and method are provided for implementing relatively low temperature joining processes, including displacement/vibration welding techniques and/or heat staking techniques, in a process of building up laminate layers to form and/or manufacture three-dimensional objects, parts and components in additive material (AM) manufacturing systems. A multi-stage 3D object forming scheme is described involving steps of laminate cutting (with lasers or other cutting devices); laminate transport between processing stations (including using one or more of conveyors, robotic pick and place devices and the like); laminate stacking, clamping and adhering through comparatively low temperature welding or other mechanical joining (including displacement/vibration welding or heat staking); and mechanical surface finishing (via CNC machining or other comparable process).

A method for producing elasticized composite side panels and non-elasticized side panels, comprising: feeding a continuous web of a first non-extensible material having longitudinal side edges along a first direction parallel to a longitudinal axis of said web, forming in said web, in a position within said longitudinal edges, and at a pitch, a plurality of oblong openings having a major axis substantially parallel to the longitudinal axis of said web, each opening having a maximum transverse dimension with a first length, a maximum longitudinal dimension with a second length, and two longitudinal end zones, forming a plurality of rectangular elements of elastic material having in a relaxed condition two minor sides with a first dimension greater than said first length and two major sides with a second dimension at least equal to said second length of said oblong openings, said elements of elastic material being elastically extensible at least along the first dimension, transferring each of said rectangular elements of elastic material in a relaxed condition onto said continuous web at each oblong opening and in a substantially centered position with respect thereto, welding each rectangular element to said continuous web along at least the respective longitudinal edges superimposed on the longitudinal edges of each oblong opening, so as to form a continuous composite web, making transverse cuts at predetermined intervals on said continuous composite web so as to remove transverse portions from said continuous composite web comprising the longitudinal end zones of each oblong opening and the corresponding minor sides of each respective rectangular element of elastic material, to form alternately individual elasticized composite panels comprising said elastic material and individual non-elasticized panels not comprising said elastic material.

Aspects of the present disclosure relate to methods and apparatuses for manufacturing absorbent articles, wherein discrete zones of protrusions may be formed on a substrate. In some configurations, the protrusions may be formed as hooks. When forming the discrete zones of protrusions, localized speed variances may be imparted to the advancing substrate to ensure the adequate time to form the protrusions is provided. As such, protrusions may be formed on portions of the substrate that have been temporarily stopped or slowed to relatively slow speeds. The substrates with zones of protrusions may then be incorporated into products, such as assembled absorbent articles, so as to place the protrusions in desired positions on the absorbent articles. As such, the methods and apparatuses herein allow for the use of hook forming techniques on substrates in article manufacturing processes that provide flexibility in such configurations without sacrificing desired manufacturing speeds.
