Abstract
Abstract Apparatus and process for simultaneous crimping and commingling of continuous filament yarns are provided. The yarn is introduced as feed into a contact chamber in which the yarn is contacted with a heated fluid, such as steam, at an angle of not greater than about 85* with respect to the yarn passage axis, and at a fluid velocity sufficient to vibrate the yarn and cause it to impact upon an impacting surface. The impacted yarn, together with the heated fluid, is then directed into an energy tube wherein the impacted yarn absorbs heat from the heated fluid. The heated yarn then passes into a stuffer tube wherein the flow of yarn is impeded, thereby establishing a yarn plug from which crimped and commingled yarn is subsequently removed.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
148 words
A process for simultaneously crimping and commingling continuous filament yarn, which comprises: a. feeding the yarn into a contact zone; b. contacting the yarn in said contact zone with heated fluid at an angle of not greater than about 85* with respect to the axis of yarn passage through said contact zone, said heated fluid having a fluid velocity sufficient to vibrate the yarn and to cause the yarn to impact upon an impacting surface; c. passing the impacted yarn and heated fluid into a heat absorbing zone wherein the yarn absorbs at least a portion of the heat from said heated fluid; d. directing the yarn under the action of heated fluid into a texturizing zone wherein the flow of yarn is impeded, thereby establishing a yarn plug; e. exhausting heated fluid from said texturizing zone; and f. removing crimped and commingled yarn from said yarn plug.
Claim 2
Dependent Claim
148 words
A process for simultaneously crimping and commingling continuous filament yarn, which comprises: a. feeding the yarn into a contact zone; b. contacting the yarn in said contact zone with heated fluid at an angle of not greater than about 85* with respect to the axis of yarn passage through said contact zone, said heated fluid having a fluid velocity sufficient to vibrate the yarn and to cause the yarn to impact upon an impacting surface; c. passing the impacted yarn and heated fluid into a heat absorbing zone wherein the yarn absorbs at least a portion of the heat from said heated fluid; d. directing the yarn under the action of heated fluid into a texturizing zone wherein the flow of yarn is impeded, thereby establishing a yarn plug; e. exhausting heated fluid from said texturizing zone; and f. removing crimped and commingled yarn from said yarn plug.
Claim 3
Dependent Claim
12 words
A process according to claim 1 wherein said heated fluid is steam.
Claim 4
Dependent Claim
39 words
A process according to claim 1 wherein the yarn is contacted in said contact zone with heated fluid at an angle of not greater thAn about 45* with respect to the axis of yarn passage through said contact zone.
Claim 5
Dependent Claim
30 words
A process according to claim 1 wherein said contact zone conically converges in the direction of yarn passage therethrough and defines a conical angle of not greater than about 85*.
Claim 6
Dependent Claim
13 words
A process according to claim 1 wherein said contact zone is substantially cylindrical.
Claim 7
Dependent Claim
45 words
The process according to claim 1 wherein the yarn is fed to the contact zone substantially along the longitudinal axis of said zone and wherein the yarn is contacted in said contact zone with heated fluid at an angle of between about 5* and 45*.
Claim 8
Independent Claim
119 words
An apparatus for simultaneous crimping and commingling continuous filament yarn, which comprises: a. a contact chamber assembly including a contact chamber, yarn inlet means for feeding yarn into said contact chamber and fluid supply means for introducing heated fluid into said contact chamber substantially along an axis which forms an angle of not greater than about 85* with the axis of yarn passage through said contact chamber; b. an energy tube wherein the yarn absorbs heat from said heated fluid, said energy tube communicating with said contact chamber; and c. a stuffer tube assembly including a stuffer tube for texturizing said yarn and a stuffer receiver, said stuffer tube and said stuffer receiver communicating successively with said energy tube.
Claim 9
Independent Claim
119 words
An apparatus for simultaneous crimping and commingling continuous filament yarn, which comprises: a. a contact chamber assembly including a contact chamber, yarn inlet means for feeding yarn into said contact chamber and fluid supply means for introducing heated fluid into said contact chamber substantially along an axis which forms an angle of not greater than about 85* with the axis of yarn passage through said contact chamber; b. an energy tube wherein the yarn absorbs heat from said heated fluid, said energy tube communicating with said contact chamber; and c. a stuffer tube assembly including a stuffer tube for texturizing said yarn and a stuffer receiver, said stuffer tube and said stuffer receiver communicating successively with said energy tube.
Claim 10
Dependent Claim
35 words
An apparatus according to claim 7 wherein said contact chamber defines a passage which conically converges in the direction of yarn passage therethrough and which defines a conical angle of not greater than about 85*.
Claim 11
Dependent Claim
45 words
An apparatus according to claim 7 wherein said fluid supply means is adapted for introducing heated fluid into said contact chamber substantially along an axis which forms an angle of not greater than about 45* with the axis of yarn passage through said contact chamber.
Claim 12
Dependent Claim
15 words
An apparatus according to claim 7 wherein said contact chamber defines a substantially cylindrical passage.
Claim 13
Dependent Claim
68 words
An apparatus according to claim 7 wherein said yarn inlet means is adapted for feeding yarn into the contact chamber substantially along the longitudinal axis of said chamber, and wherein said fluid supply means is adapted for introducing heated fluid into said contact chamber substantially along an axis which forms an angle of between about 5* and 45* with the axis of yarn passage through said contact chamber.
