摘要:
The invention provides novel integral man-made vitreous fibre batt products having a core section in which the concentration of an additive material is greater than the concentration in each of the face sections. Three novel processes are provided which can be used to produce such a product. One in particular comprises forming a primary web of product, applying additive to the centre region of the primary web and cross-lapping the web to form a secondary web so that the centre region to which additive has been applied mainly forms the core section of the product.
摘要:
A method for authenticating a textile product wherein a colorless composition is applied to at least one portion of at least one thread of the textile product. The composition includes one of a pair of colorformer (A, B) and an activator (22) which react when mixed to produce a spectral response (23). The textile product is authenticated as genuine by applying the other of the pair of colorformer and activator to at least one portion of the at least one thread to produce the spectral response. The textile product may be a thread (21) or a woven label (20).

A method of producing a mineral fiber-insulating web comprises the steps of firstly producing a first non-woven mineral fiber-web being a loosely compacted mineral fiber web of a low area weight. The first material fiber web contains mineral fibers arranged generally in the longitudinal direction of the mineral fiber web. Secondly, the first material fiber web is moved in the longitudinal direction of the web and folded transversely relative to the longitudinal direction and parallel with a transversal direction of the first mineral fiber web, so as to produce a second mineral fiber-web containing mineral fibers arranged generally perpendicular to the longitudinal and transversal directions. Thereupon, the folded mineral fiber web is cured for bonding the mineral fibers together so as to produce the mineral fiber-insulating web comprising a central body containing mineral fibers arranged generally perpendicular to the longitudinal direction of the mineral fiber web.

An air laying forming station (ALFS) forms a nonwoven substrate from a first material and a second material having at least one physical characteristic substantially different from the first material. The ALFS includes a forming chamber and a forming screen, moving relative to the forming chamber, for receiving deposit of the first and second materials. A first distributor supplies the first material. A vacuum source provides an air flow which deposits the first material onto the forming screen. A second distributor delivers the second material, independently from the first material between the first distributor and the forming screen, by gravity along one or more baffle members.

The present invention relates to a process for making a multi-layered absorbent composite web. The web comprises at least a primary material and a secondary material. The primary material comprises apertures wherein fibers from the secondary material are inserted for fluid capture and transport. The secondary material may form a layer on the primary material once the apertures of the primary material are filled. That is, the secondary material may form a layer of material placed adjacent to the bottom surface of the primary material.

An hydraulic treatment apparatus (10) and method is provided for finishing and upgrading the quality of filament cloth materials. The fabric (12) is supported on a member (52, 54) and impacted with a uniform, high density jet, fluid curtain (34, 70) under controlled process energies. Low pressure/low energy treatments spread filaments in the fabric to reduce air porosity and provide improved uniformity in material finish. High pressure and energy treatments increase fabric bulk and porosity. Fluid treated fabrics of the invention demonstrate substantial improvement in at least two of uniformity, cover, opacity, increased or decreased bulk, increased or decreased air permeability, abrasion resistance, tensile strength, edge fray, and seam slippage.

A glass fiber mat (104) includes glass fibers impregnated with a binder and then cured. A predetermined pattern of relatively high and low concentrations of binder is formed throughout the length of the glass fiber mat. The pattern includes at least one portion (106,108,110) of the mat having a relatively high concentration of binder adjoining a portion (112,114) of the mat having a relatively low concentration of binder and is produced either by selectively applying liquid binder to the glass fibers via an applicator or selectively removing liquid binder from the glass fibers via a vacuum before curing. The cured mats can be cut along an area of high binder concentration to produce cut edges which resist breaking and tearing. Shingles formed from such glass fiber mats have improved tear resistance and pliability.
