СПОСОБ ПОЛУЧЕНИЯ ПРЯЖИ

Способ может быть использован для получения пряжи с повышенной объемностью и позволяет улучшить ее теплозащитные свойства. Согласно способу в сформированную пряжу вводят латексное связующее во вспененном состоянии с последующей термообработкой пряжи. После термообработки пряжу полностью раскручивают в направлении, противоположном начальной крутке, и ворсуют. Термообработка пряжи с введенным в нее вспененным связующим обеспечивает образование наибольшего числа склеек при наиболее уплотненной структуре пряжи, что способствует сохранению деформационных свойств пряжи при ее последующем раскручивании и ворсовании. При полном раскручивании пряжи с сохранением в ней склеек достигается увеличение ее поперечника, снижение плотности, увеличение объемности и повышение теплозащитных свойств пряжи.

Ворсовая нить и способ ее получения

Изобретение относится к производству фасонной ворсовой нити и способу ее получения и позволяет расширить ассортимент ворсовой нити за счет придания ей фасонного эффекта. Ворсовая нить содержит стержневую нить с закрепленным на ней по периметру волокнистым ворсом, который на неравномерно расположенных по ее длине участках вьтолнен из ворсовых волокон разной длины и тонины, одного или разного цвета, с различной их плотностью и различным направлением расположения. Ворсовую нить получают путем проведения покрытой клеем заземленной стержневой нити под натяжением через электростатическое поле высокого напряжения, подачи в него ворсовых волокон разной длины и тонины и одного или разного цвета и нанесения их в поле на стержневую нить по ее периметру с последующей сушкой нити перед ее намоткой. При проведении стержневой нити через эле к- тростатическое поле изменяют напряжение поля и/или натяжение стержневой нити, и/или количество подаваемьгх в поле ворсовых волокон. 2 с,п. ф-лы, 3 ил.

Singeing and warping machines

... 335,916. Triggs, W. W., (Standard- Coosa-Thatcher Co.). June 29, 1929. Stop-motions.-In a, combined singeing and warping machine, an electric stop-motion is operated and the burners turned off when the yarn breaks or when a measured length of yarn has passed through the machine. On breakage of a yarn, a detector completes a circuit which operates a mercury switch, and causes a relay to disconnect the mains supply. This stops the motor, and de-energizes an electromagnet which controls a. latch holding the bracket 62 against the tension of the chain 63; thus the weight 65 causes the lever 61 to rotate. The lever, through a series of links, rotates the burners to an inoperative, position. The circuit to the mercury switch is also completed, and the stop-motion operated when a given length of yarn has passed through an attached measuring machine, or when a switch is closed manually.

Suture anchoring assemblies and methods of use

A suture anchor assembly and methods of use will now are disclosed for the repair of human or animal tissue defects. The suture anchor assembly is capable of being inserted into a tissue or bone while also being able to create an expanded profile when subjected to a retrograde force. This expanded profile anchors the assembly into the tissue or bone by a changing of position of elements of the assembly relative to other assembly elements. Embodiments of the suture anchor assembly and methods are capable of precisely positioning assembly elements in the tissue or bone to effectively repair the defects.

Tissue anchor insertion system

A tissue anchor insertion system for inserting a tissue anchor into a body tissue such as bone, comprising a cutting device having a sharp leading end to create an aperture in the bone for insertion of the tissue anchor therein. The cutting device is deployed through a sleeve which is a close fit with the cutting device. The distal end of the sleeve is typically configured to penetrate the tissue in which the tissue anchor is to be inserted. A tissue anchor is also deployed through the sleeve, after the sleeve is in position, on a delivery device configured to support the tissue anchor during its insertion into the tissue. Typically the leading end of the sleeve is embedded within the tissue when the tissue anchor emerges from the distal end during the insertion process, so the tissue anchor is not damaged by insertion through the tissue.

Knotless suture anchor for securing soft tissue to bone

A suture anchor for anchoring a length of suture to bone, the suture anchor comprising: an elongated expandable body having a distal end surface, a proximal end surface, an exterior sidewall extending between the distal end surface and the proximal end surface, and an interior passageway extending between the distal end surface and the proximal end surface; and an actuator comprising a distal end, a proximal end and a shaft extending between the distal end and the proximal end, the distal end of the actuator comprising a suture capture mechanism movably disposed relative to the elongated body; wherein the suture capture mechanism comprises a diamond-shaped structure configured to provide an opening into the interior thereof.

Methods and devices for soft tissue and joint repair

Disclosed herein are methods and devices for tissue and joint repair. Devices as disclosed herein can be used during surgical procedures, for example, to repair biceps tendons, elbows, shoulders, and knees. Methods disclosed herein relate to methods for repairing the same using the disclosed devices.

Bioabsorbable suture anchor system for use in small joints

A bioabsorbable suture anchor for anchoring soft tissue to a bone is provided. The suture anchor is configured to toggle and anchor itself inside a bone cavity of a small joint. The anchor comprises an elongate body defined by a longitudinal axis, a first, leading end and a second, trailing end. The elongate body also has two opposed surfaces between the first and second ends, and a plurality of sidewalls extending between the two opposed surfaces. Extending from one of the sidewalls is a flared portion that is formed on the second end of the elongate body. A suture channel extends between the two opposed surfaces. The suture channel is formed in the elongate body for passage of a suture strand therethrough, such that pulling on an attached suture strand effects toggling of the anchor inside a bone cavity.

Bone anchor

A bone anchor comprises a screw body and a flange, which are joined together in a way to keep their rotation independent from each other. In implanting the screw body into a bone, the flange does not rotate to prevent twisting and/or snarling of the suture in wounded bone from occurring.

Surgical Filament Snare Assemblies

A surgical filament snare assembly including an anchor capable of being fixated in bone and having a filament engagement feature. A first filament has a noose with first and second noose limbs connected, preferably slidably, to the filament engagement feature. The first and second noose limbs emerge from the anchor as first and second free filament limbs that are capable of being passed through tissue to be repaired and then passable through the noose. The noose is capable of receiving the free filament limbs and strangulating them when tension is applied to at least one of the free filament limbs and the noose to enable incremental tensioning of the tissue after anchor fixation. Preferably, the snare assembly further includes a flexible sleeve joining at least some portion of the first and second free filament limbs to facilitate passing of the free filament limbs as a single unit.

Multi-loop adjustable knotless anchor assembly, adjustable capture mechanism, and method for repair

An apparatus for use in internal fixation of acromioclavicular joint dislocations of a shoulder , the shoulder including a clavicle , a coracoid process and an acromium , the apparatus comprising:a first suture anchor;a second suture anchor, the first and second suture anchors being adapted for engagement in or on the clavicle and the coracoid process, respectively;a flexible coupling mountable, in use, between the first and second suture anchors; anda needle releasably securable to at least one of the first and second suture anchors, in which the first and second suture anchors each have at least first and second apertures and the flexible coupling is a first suture which is double looped through the first and second suture anchors.2. The apparatus according to claim 1 , in which the flexible coupling is a first suture which is fed claim 1 , in use claim 1 , through a first aperture of the second suture anchor claim 1 , and through claim 1 , in turn claim 1 , the second and first apertures of the first suture anchor and through claim 1 , in turn claim 1 , second and first apertures of the second suture anchor claim 1 , and through claim 1 , in turn the second and first apertures of the first suture anchor and through the second aperture of the second ...
