The invention pertains to a method of monitoring the quality of a mattress during its lifetime, wherein the mattress is an assembly of multiple separate parts, wherein the parts are mechanically interconnected, the method comprising during its lifetime, assessing at least one property of the mattress, determining whether or not the property meets a predetermined specification, and when the property does not meet the predetermined specification, identifying a part of the said multiple separate parts that corresponds to the property, removing the identified part from the assembly and optionally replacing the removed part with a replacement part, wherein the mattress that is monitored is manufactured by forming the mechanical interconnection with an adhesive, which adhesive has a first order phase-transition temperature between 80&#xb0; C. and 180&#xb0; C., at which temperature the adhesive undergoes a solid-liquid transition, and wherein before the said removing of the identified part, the adhesive with which this part is interconnected with other parts in the assembly is heated to a temperature above its phase-transition temperature, whereafter the identified part is grasped and pulled out of the assembly. The invention also pertains to a method of manufacturing a mattress suitable for use in this monitoring method.

Method of monitoring the quality of a mattress

The present invention pertains to a method for manufacturing a laminated textile product comprising providing a first intermediate product comprising a primary backing having a front surface and a back surface, and yarns stitched into the primary backing, the yarns extending from the front surface of the backing material, feeding the intermediate product along a body having a heated surface, the back surface being pressed against the said heated surface, to at least partly melt the yarns present in the intermediate product to bond the yarns to the backing, wherein the part of the back surface that is pressed against the heated surface has a relative speed with respect to the heated surface, so as to provide a second intermediate product having a calendered back surface, providing a dimensionally stable carrier sheet or secondary backing, and connecting the second intermediate product to the carrier sheet by providing a hot melt adhesive between the calendered surface and the sheet, and pressing the sheet to the second intermediate product to form the textile product.

The invention relates to two-component chemical fastening systems, the A-component containing an unsaturated polyester and a reactive diluent, and the B-component containing a peroxide and an extender, wherein the extender is either a monomeric component according to formula 1(A&#x2014;CH&#x2550;CH&#x2014;O)&#x2014;R &#x2003;&#x2003;(formula 1)or a resinous compound comprising, in a covalently built-in manner, a component having vinyl ether group(s), and the content of the peroxide in the B-component is from 0.5 to 99 wt. %. In the formula A, R and n are specified as hydrogen or Calkyl; C(hetero)-aliphatic with hydroxyl or amino groups, or poly(C)glycol with 2&#x2013;120 glycol units; and 1 to 4, respectively. The resinous compounds with built-in vinyl ether group(s) (0.5 to 50 wt. %, calculated as indicated) are obtained by reaction of a mixture of appropriate amounts of: The invention also relates to methods for preparing (the B-component) of such two-component chemical fastening systems, as well as to use of the systems for chemical fastening.

Two-component chemical fastening systems

The invention relates to peroxide compositions comprising a reactive diluent for the peroxide, wherein the diluent is either a component containing one or more vinyl ether group(s) and having a monomeric structure according to formula 1, (A&#x2014;CH&#x2550;CH&#x2014;O)&#x2014;R, or is a suitable resinous compound comprising, in a covalently built-in manner, a component containing one or more vinyl ether group(s). In the formula The resinous compounds comprising, in a covalently built-in manner, a component containing one or more vinyl ether group(s)are obtained by reaction of: The invention also relates to the preparation of such compositions and to the use of such reactive diluents for peroxides in radically curing of unsaturated polyester resins for structural applications.
