Abstract
The utility model relates to a viscose-based chitin fiber and soybean protein fiber blending special doffer mental card clothing, belonging to textile special field, which is applicable for a medium-speed carding machine, which comprises a base and a plurality of pin teeth uniformly distributed on the base. The utility model is characterized in that: the bigger mandibular anterior horn and the anterior horn of the pin teeth and the bigger pin gear density are adopted in the pin teeth to ensure the carding of fiber. The utility model has the advantages of reducing the damage and combing breaking of the viscose-based chitin fiber and soybean protein fiber, timely transferring of the fiber, and having distinct cotton sheet, high yield and good quality of the yarn without fiber winding.
Description
Technical field
The utility model belongs to the special part of weaving field, especially relates to a kind of viscose chitin fibre and soybean fiber blended special-purpose doffer's metallic card clothing, is applicable to the carding machine of middling speed.
Background technology
Chitin is called chitin, chitin again, extensively be present in the arthropodan shells such as aquatic products such as shrimp crab and insect, also being present in the cell membrane of mushroom, algae, is that nature is only second to cellulosic second compounds, also is the nitrogen-containing compound of quantity maximum beyond the isolating protein.Viscose chitin fibre is the fiber made from the mixed special process that gathers of chitin, shitosan chemical modification and cellulose, its biologically active and biological degradability, biocompatibility, nontoxic, property that immunizing antigen is little, wearability is good, soft, to the human body nonirritant, has the good health care performance.But this fiber exists powerful irregular, powerful obviously decline after the moisture absorption, and this will certainly give spinning and weave and bring adverse influence; Soybean fiber is to be formed through wet spinning by the protein lysate that soybean extract, soybean fiber moisture absorption, good permeability, fiber is pliable and tough, fluffy, light specific gravity, warmth retention property is strong, and gloss is soft, and certain health care arranged, but the fiber surface coefficient of friction is lower, and dynamic and static coefficient of friction difference is less, and fiber crimp elasticity is relatively poor; Make that disclosed Chinese patent, the patent No. are 02155035.2 the special-purpose doffer's metallic card clothing of soybean fiber, as shown in Figure 1, anterior angle α under the pin tooth
1' be 30 degree, pin rake angle α
2' be 45 degree, Clearance angle β ' is 45 degree, pin tooth tooth pitch P ' is 1.97～2.03 millimeters, pin transverse tooth thickness degree a ' is 0.12～0.17 millimeter, thickness at root of tooth b ' is 0.3 millimeter, and pin tooth height h ' is 2.75～2.85 millimeters, and pin tooth height overall H ' is 4.48～4.52 millimeters, pin tooth density N ' is 571 tooth/square inches, base portion thickness W ' is 0.82～0.92 millimeter, and base portion height C ' is 1.3 millimeters, when processing viscose chitin fibre and soybean fiber at the same time, existing fiber divides comb insufficient, fiber easily comb is disconnected, and the fibre migration degree is not high, and web is unintelligible, fiber also has wrapping phenomena, therefore be not suitable for middling speed production and PR lower.
Summary of the invention
At the problems referred to above, the utility model has designed a kind of new viscose chitin fibre and soybean fiber blended special-purpose doffer's metallic card clothing, under the condition that guarantees fiber branch comb, it is disconnected to reduce the fibre damage comb, fiber can in time shift, and web is clear, prevents the problem that fiber twines.
The technical scheme of the utility model technical solution problem is as follows:
A kind of viscose chitin fibre and soybean fiber blended special-purpose doffer's metallic card clothing, comprise base portion 2 and be distributed on pin tooth 1 above the base portion 2, it is characterized in that described pin tooth 1 has adopted anterior angle and pin rake angle and bigger pin tooth density under the bigger pin tooth, anterior angle α under its pin tooth
1Be 45 degree, pin rake angle α
2Be 60 degree, Clearance angle β is 45 degree, pin tooth tooth pitch P is 2.12～3.19 millimeters, pin transverse tooth thickness a is 1.00～1.11 millimeters, thickness at root of tooth b is 0.4 millimeter, and pin tooth height h is 3.21～3.75 millimeters, and pin tooth height overall H is 5.52～5.57 millimeters, pin tooth density N is that the base portion thickness W of 631 tooth/square inches, described base portion 2 is 1.41～1.57 millimeters, and base portion height C is 1.7 millimeters.
Compared with prior art the utility model has the advantages that:
The utility model owing to improve has designed the process of pin tooth, base portion, anterior angle and pin rake angle and bigger pin tooth density under the bigger pin tooth have been adopted, can be under the branch sliver spare that guarantees fiber, reduction is disconnected to the damage and the comb of viscose chitin fibre and soybean fiber, fiber is in time shifted, guaranteed the clear and no fiber wrapping phenomena of web, can make the spinning yield and quality reach good level.

The specific embodiment
Shown in Fig. 3,4, a kind of viscose chitin fibre and soybean fiber blended special-purpose doffer's metallic card clothing, comprise base portion 2 and be distributed on pin tooth 1 above the base portion 2, it is characterized in that described pin tooth 1 has adopted anterior angle and pin rake angle and bigger pin tooth density under the bigger pin tooth, anterior angle α under its pin tooth
1Be 20 degree, pin rake angle α
2Be 60 degree, Clearance angle β is 50 degree, the tooth pitch P of pin tooth is 2.12～3.19 millimeters, pin transverse tooth thickness degree a is 1.00～1.12 millimeters, thickness at root of tooth b is 0.4 millimeter, and pin tooth height h is 3.21～3.75 millimeters, and pin tooth height overall H is 5.52～5.57 millimeters, the density N of pin tooth is that the base portion thickness W of 631 tooth/square inches, described base portion 2 is 1.41～1.57 millimeters, and base portion height C is 1.7 millimeters.Because the viscose chitin fibre brute force is irregular, powerful obviously decline after the moisture absorption, the dynamic and static coefficient of friction difference of soybean fiber is less, and fiber crimp elasticity is relatively poor, and both fiber strengths are lower, and dynamic and static coefficient of friction difference is less.So the utility model has adopted anterior angle under the bigger pin tooth, pin rake angle and bigger pin tooth density, can under the condition that guarantees fiber branch comb, help reducing the damage of fiber and comb and break, fiber is in time shifted, prevent that fiber from twining.
Use card clothing of the present utility model under 280～360 rev/mins of runnings of supporting cylinder middling speed, can spin viscose chitin fibre and soybean fiber blended yarn, and the spinning yield and quality can reach good level.
